Vegeta was going to stay for a week there at the base. He first planned to make a training regime for all the girls at the base to get their powers up to the max they could withstand.
He made a plan for Momo, where with the help of Bulma and Dr Briefs, he designed some targets that can move at the speed of light but have to use his Ki to coat them so that they don't encounter any resistance while moving. Which is easy to solve as he will be leaving 5 clones at base that can recharge them at any time.
Bulma, Momo and Toru will be using the same training plan as they are gunslingers. Momo and Bulma rely more on Gunslinging whilst Toru relies on gunslinging and Assassination. Toru's assassination could be trained with Scathach who was a weapons expert anyway.
He taught a set of his own martial arts to Tio and asked Ophis to practice with her. Kratos looked at Vegeta like he wanted to drink his blood when he saw the hardships Vegeta put on Ophis but Vegeta persuaded him with reason and he agreed reluctantly.
Rest of the DxD girls and Nejire were instructed to work out in the Gravity Chamber to enhance their perseverance, endurance, strength and help them grow their energy reserves. Especially DxD girls, who couldn't take advantage of this world's strength growth had to spend more time in Gravity chamber and at higher settings to grow effectively.
After finishing these girls, He shifted his attention to all the parents at the base. He designed their individual training programs. His parents had creation skills, so they were given theory books and some action mangas to read. Imagination is the best tool for Creation skills. With the action manga, they can get variety of different ideas to help them enhance their strengths.
Toru's parents were trained in the same way as her to become natural and the best assassins. Covert tactics, various enhanced firearms and other things to make sure they have really good arsenal. Capsule technology was fully used for them to store various weapons and ammunition, all over their bodies.
Nejire's parents also had varying degrees of energy manipulation. Not as strong as Nejire but they could work around it. Nejire's mom couldn't use energy for projectile attacks but could clad her body in energy to make it stronger. Her dad had the same problems but he could change the nature of it.
They were taught suitable martial arts and were instructed to participate and fight with multiple enemies at the same time. Of course, they had to start with one-on-one then slowly expand their instincts and fight multiple at the same time. This thing was actually done by all the people on the base except Vegeta and Kratos cause they were already used to it.
Vegeta practices this with his clones and fights multiple enemies at the same time. But against absolute strength, all kinds of fancy tricks become useless sometimes. It can make some distractions and a bit of breathing room but won't do much else when the force is too strong to withstand.
Suddenly, Vegeta had a little thought in his mind. Could he create a black hole. Black hole is an entity which has mass compressed so tight that it literally starts to make strong gravitational pull around it. Vegeta had the idea to try compressing a heavy Iron ball into the most compression he could get.
He took everyone out of the base and into a deserted area on the continent. A ball of iron which was the size of a house was there. Vegeta excavated this Iron from a mine on the continent. The continent had everything that a normal continent would have. Mines, petroleum, etc it was just a matter of finding it.
He first covered everyone with a barrier that was very sturdy and isolated the outside forces from them except Gravity. He covered the iron ball with barrier and started to compress the barrier slowly. The compression first went smoothly till the ball started to make nuclear fusions and compressed into a star, the size of a Basketball.
The temperature in the surroundings suddenly rose tremendously but due to the barrier, it was isolated inside the barrier immediately. This time, the compression slowed down to a crawl. It was really slow as the mass of iron had become a star and the nuclear fusion inside was opposing Vegeta's compression.
Vegeta immediately went Super Saiyan and the compression sped up a bit. Seeing that it was still quite slow, he transformed into Super Saiyan 4 and continued Compressing it at the fastest speed that he could. The basketball sized Star slowly compressed more and more and started to become smaller.
When the star was becoming around 5mm in diameter, The star collapsed and an intense gravitational pull broke out with a black hole as the centre. Vegeta looked at his creation in marvel. Due to the barrier, outside world couldn't feel anything but inside the barrier was another matter.
Vegeta looked at the Blackhole up close in fascination. Dr. Briefs immediately came out of the barrier and sprinted in front of Vegeta and looked at the Block hole like he found his long lost lover. He was looking at the Black hole really seriously without blinking an eyelid.
"Vegeta, Can you make this again in my lab. I want to study it, can you?" He grabbed Vegeta by the shoulders and there was an intense light in his eyes. He was looking at Vegeta like a hungry ghost. Vegeta backed off a little from him.
"I can, my clone can create it anytime. Go bother him". Vegeta said and immediately got inside the barrier to cuddle with his girls. He was still getting Goosebumps from Dr. Briefs gaze at him.
(A/N: Okay guys, I thought that I should write another Fanfic after this one and the New one would be on Douluo Dalu.
Just want a suggestion.
I want to give my character just one martial soul unlike others where the martial souls get ridiculously many.
Either he gets the Martial Soul of a Dung beetle. Dung beetles can lift 1141 times their body weight or base strength for that matter. Meaning a very Op Martial soul. Most of the Soul abilities will be kind of passive.
or
Hercules Hammer. A tool martial spirit that multiply attack power. It would have a multiple of 1500 times by the end of the MC journey. Very Op martial spirits.
What would you guys choose. Nyahahaha)
