17 Time Chamber and training.

"Hmmm..., Someone is blocking contact with the otherworld." Trunks said as he understood the weight of this sentence. The Otherworld is probably in danger.

He has a few ideas on who may be doing that, and if it really is him, then he's far from ready to confront him, heck even approaching there might be dangerous.

"Yes, unfortunately I can't be much of help, so is there anything else ?" Baba replied to Trunks who was in a big shock.

"Can you send someone there ? Of course you don't have to go yourself !" Trunks knew baba didn't like danger.

"Hmm, I can try but it will exhaust me, but I think I can. If you want to go there, it will be risky even for you !" baba replied fiercely.

"Oh you don't have to worry, I won't go, at least for now, I will train first." Trunks was now looking very confident. He would make preparations to go to the time chamber and head there tomorrow.

"If that's all, you owe me a million Zenis." baba said.

Trunks seemed to have prepared for that and handed her a bag of money. Of course he wasn't obliged to pay but he did out of respect and it's not like this money is a lot for his mother.

"Hmm, much appreciated, you're a good boy, finally Roshi raised a fine student, hehehe !"Baba was smiling happily while caressing her bag full of money.

"Okay Bye, grandma !" Trunks replied and quickly left to dodge all the nagging baba would have done about calling her a grandma.

The next day,

"Trunks it's ready !" Bulma said as she held a box. 

It was a box full of Capsules, Trunks asked her to make preparations as he was going in training in the time chamber, he of course explained it to her, she was a bit sceptic to let her son grow so abnormally but she didn't stop him.

"There are 20 Capsules." Bulma said as she explained how she distributed all the food and water among the capsules.

"Thank you very much mom, see you in two days, and two years for me." Bulma bid him farewell and Trunks was gone again.

Trunks was now heading to Kami's lookout and was ready to enter the time chamber, He was ready to give his all. He wanted to be as strong as possible to be ready to face any menace.

Since He knew that was the real world, any menace could pop up anytime wether it is the canon from the manga or non canon.

Cell was already out in the wild and there is no guarantee he won't find another way to gain his final form, or even finish his growth much earlier.

'I need to get stronger much, much faster.' Trunks accelerated his fly speed to arrive much faster on the lookout. 

In matters of seconds Trunks was there, he then looked for Mr Popo.

"I'm here Trunks !" Mr Popo said while standing behind Trunks.

"How ?! You always seem to be behind me every time I arrive here." Trunks said a bit dejected that his senses are not keen enough to spot Mr Popo even Though he is this remarkable. "Ugh.."

"It doesn't matter, it seems you came back, May I know why ?" Mr popo dismissed.

"I came here for the time chamber. I need to train !" Trunks looked very serious. 

"Okay, please wait a few minutes, I will prepare it." Mr Popo replied.

"Ah yes, and no need for the food, I already have some with me." 

A few minutes later, Mr Popo came back and asked me to follow him, as he conducted me to the time chamber.

We arrived in front of the door," Have a safe training training trunks." Mr Popo said.

"Thank you Mr Popo."

I made my way inside and closed the door. It was magnificent. 

This place seemed peaceful and was the same as drawn in the manga. It seemed a bit too white but other all it really was a great place for training.

I left my belongings on the bed and immediately started training.

I took off my jacket and was now left with a white shirt.

I will start by continuing trying to master Super saiyan as I stopped at third grade super saiyan with Gohan who also achieved it.

I now must achieve the full power super saiyan. It is achieved by being able to stay super saiyan all the time which I already started and had little results. I can stay at least ten hours with super saiyan still active but it is nowhere near enough, goku and Gohan stayed 9 days, and didn't even detransform until the end of the battle against cell.

Trunks then got into position, his hands clenched, his back slightly lowered and shouted with all his might.

"AAAAAAAAAAHHHHHHHHH!!!!!!!!!"

A golden Aura shone in this space. His aura was immense and rose very high. His long and purple slowly turning to a bright gold color. His eyes shining a brilliant blueish-green. 

What Trunks did was release all his power, then calmed and almost seemed to be absorbing his own aura. He was trying to avoid a leak of energy, which he was quite familiar with now.

Trunks then put on a dispositive he asked his mother to make. It was in a capsule, it was made to reproduce the effects of the time chamber, and Trunks activated it at 400 times earth's gravity and started training, he stood on one finger and started doing push ups.

(Time Chamber - 1 week after entering)

After a week of training Trunks had finally been able to increase his time in super saiyan to 12 hours, which is very great.

He will continue this until he's able to stay super saiyan all the time, so he continued training, again and again.

Trunks understood one thing since he came in this world, he likes getting stronger, not just because of his saiyans instincts but he sincerely enjoy training, he takes joy in it and thinking more and more about it, he also had another goal in this world, he of course would like to save it but becoming the strongest doesn't sound so bad, right ?!

(Time Chamber - 6 months after entering)

Finally trunks was able to stay a whole day without detransforming. From there it became easier and easier and Trunks also gradually increased the gravity of the device and continued his training, basics and other things like tanking his own kikoha beam. He also continued revising the techniques taught by Roshi.

The technique he used was instead of all his body becoming big, he condensed all the energy boost in the fist. This was the technique he used against the cyborgs, It was frighteningly efficient and strong. It also increased the speed of the user.

Technically he could condense it whatever part of his body but the fist was the most simple and easy.

After a few days, Trunks still hadn't detransformed, he achieved it, he could now stay in ssj all the time so he continued honing his power and finally after a few weeks he achieved the full power ssj form. 

Trunks was very happy but there was now a much bigger wall in front of him, the Super saiyan 2.

It was achievable through training but trunks didn't know how long it would take him. But he was still very motivated.

And if he wanted to be able to protect the world, super saiyan 2 couldn't be his limit so he steeled his resolve once again.

"Let's go, if I can't achieve it before I get out, all this training would be meaningless !"

(Time chamber - 1 year and 7 months after entering)

"haaa, sigh, even after More than 1year I can't achieve super saiyan 2 !" Trunks was no longer meditating in the air and started complaining.

'I feel like I'm close but I can't quite pinpoint it.'

Trunks had grown a lot. He had surpassed the original Trunks in height and was standing at 6 feet1( 185 cm)

His body was almost 16 and his body was very well maintained, his hair was now very long, arriving at on his back. 

( He looks like Trunks at his prime but taller, ps idk how to insert pics.)

He decided to try another method. He would try getting it being angry. But how, he should just imagine but it isn't as simple as that. But he had an idea.

In the show Bulma died at the hands of goku black. He would try to imagine it.

He would hurt himself to the limit first, he still has the Senzu beans with him and hasn't abused the Zenkai boost very much. He just used them when he was getting hurt a little too much. If it doesn't work he can still heal himself.

So he starts, 

"KAAA..... MEEEEE.....HAAAA.....MEEEE...HAAAAAAA !!!!!" Trunks launch a tremendous Kamehameha and launches it. He then rushes to the other side and places himself in front of it

"AHHHHHHHH" The Kamehameha, hits him and he's very hurt.

"This is no joke...." Trunks was on the break of passing out, maybe should ha have not Done that, his clothes were torn but he still resisted most of the impact or he would have turned to dust.

Then he starts, images of his mother getting killed.

When he first thought of this method he thought it wouldn't work and it was embarrassing to do that, but he didn't know his saiyan part would amplify the emotions.

It was as if it was happening in front of him, his mother getting grabbed by the collar, then getting killed by black.

Then it happened, Trunks was enraged by those, it was as f it was a flashback more than imagination, the future....

Then an aura quickly invaded the space.

(Unmei no hi Tamashi vs tamashi starts playing in your head)

His hair rose up and mini lightnings strings were stranding around him, 

Tears, flowed on Trunks face.

"I didn't know it would be this efficient, I mustn't let that happen. I will definitely be strong enough !"

The transformation didn't last very long and Trunks was in bad condition, he immediately took a Senzu bean and continued training.

He trained so he could master ssj2 and continued to hone his techniques. He also trained with his sword but was not that much of a swordsman, maybe should he learn swordsmanship.

....

(Time Chamber - 2 years after entering)

------------------------------------------------------------------------------------------------------------------------

Trunks emerged from the time chamber. 

After bidding farewell to Mr Popo, he headed towards his home. It had been only two days outside but for him, it was 2 years, he missed his mom.

"Let's go then !" Trunks screamed before taking off at high speed.

It was just a matter of seconds before Trunks arrived at capsule corp. 

He was approaching and passed through the back door, employees came back as peace came back, so capsule corp became active.

"Mom !" Trunks called his mother, he started searching for her and went to her lab. There she was.

"Mom, I'm back !" Trunks stated, Bulma turned to face him and obviously was shocked, her son was now taller and older. she ran up to him and hugged him.

"Oh my, you really trained a lot, your body is really well built !" Bulma said while grinning."I wouldn't be impressed if you start breaking girls heart."

Trunks blushed, he was embarrassed. Bulma continued rambling about how he had grown and asked if he wanted to cut his hair.

"No thanks mom, I like it this way." Trunks replied as he preferred this look.

After a while, Trunks was now in his room and wondered what ho would now, he just had to wait 2 years now. Of course he would train but for now it's boring there really isn't anything to do now. Babidi won't find about earth for a while, they appeared after trunks defeated the androids and cell. Trunks was already 18 at the time so they aren't coming here for now.

But the energy from Super saiyan 2 may attract them into coming here.

"Ah ! I remember !" Trunks remembered the frieza ship when frieza came to earth to defeat Goku and he also remembered his mom taking some parts of it. He should ask her to look for planets record, maybe he would find about planet yardrat !

So he did just that.

"Hmm, planet record, what ? you want to go into space ?" Bulma asked.

"Yes, there is a certain planet Gohan told me about from his father, a planet where people learned strange techniques !" Trunks replied. 

"Hmm, okay, give me 2 months, I'll decrypt it and search information in it, and of course if you want to go there you should have a decent ship." Bulma said with enthusiast.

"Thanks mom !" Trunks was excited, he was desperate to find a way to go on planet yardrat. He could learn instant transmission but also helps him better control his power but above all, learn forced spirit fission, which would help him beat the foe in the otherworld if he really is who he thinks he is.

Trunks with that was more than motivated, and continued his training outside of the time chamber and came back to his gravity room, he continued to further enhance his mastery of super saiyan 2.

So after 2 weeks, Bulma had finished decrypting the Informations of frieza ship. It was possible Yardrat informations were there, so Bulma then passed onto making his ship, there was the ship goku used to go to namek but it was in bad shape. His mom would repair it and update it.

He had no choice but to wait so of course he continued his training.

Till one day, Trunks as usual was training in his gravity room but was interrupted by a strong energy approaching the earth, although this energy was not that strong, this person was incomparably powerful for an earthling. 

He wasn't that alarmed but that person was heading towards him and he didn't want to take risks.

"Mom, I'm going out for a bit !" Trunks said to Bulma. "Okay, be careful ! even though I don't know what you would be afraid of !" Bulma said while laughing. She knew of her son progress and knew of the super saiyan 2 a transformation even Goku hadn't achieved.

"Let's get out of town !" Trunks quickly flew and headed towards the plains a bit far from the city.

As he landed and waited he finally saw what was headed toward him, a capsule, and he knew the design of it, it resembled the capsules of frieza.

"I may know who it is, the only person that could come here at this time should be him."

The capsule landed not far from him and someone came out.

A young man with short spiky black hair, a blue detector, and a saiyan armor with a monkey tail.

Trunks who it was, it was table vegeta's brother !

'I shouldn't know who it is but this is my uncle I think, he is older than he was on the show, but he still looks fairly young, but that's normal. He came far later. But he doesn't seem to have his so called wife.'

As tarble was getting out he headed towards me.

"Hi ! My name is Tarble. I came towards you because you had the strongest Power level but you are not the one I thought you would be. Do you know by any chance someone called vegeta." Tarble addressed Trunks.

"Oh, hi ! Yes I know Vegeta, But he is no longer here. He is Dead" Trunks replied.

"Oh... I see,-" Trunks interrupted him "But do not worry, I am his son."

"What ?! My older brother had a son !"Tarble was shocked when he heard this. His brother was a proud saiyan and he knew his brother was ruthless. So to know that his brother had a son with a woman who was not saiyan, was a bit strange for him to hear.

"But I don't think you can help me. There are people pursuing me and they are very strong. With your Power level being only 5000, I don't think you can defeat Them." Tarble replied to Trunks "I think it's better if I flee, I will cause trouble for your planet !" he was ready to get back to his ship but I stopped him.

"Don't worry Uncle, I might not seem like it but I'm very strong !" Trunks smiled and started raising his power level.

"What, Your power is rising and at an incredulous speed !" Tarble was shocked by the strength of his tall nephew who seemed bottomless as the scouter finally exploded.

"Don't worry Uncle, I think I can take them on !" Trunks said knowing who Tarble was talking about, Avo and Cado.

They are not that strong and can be defeated with a simple super saiyan. 

"O-Okay, then, they will arrive here in a few hours." Tarble warned his nephew but still had a few doubts.

"Then before they come let me take you to see my mom, you sister in law , haha !" Trunks laughed, it seemed a bit weird to have an uncle but he liked having company.
