The next day the city lord gave his first lesson and it flabbergasted all of them with the exception of Atrog and Broly. The lesson was about the pathways of the so-called meridians, who run through their whole body, transporting the ki where they wanted it to be. It was so surprising for them because they didn't know those paths existed. It just came natural to them. On second thought there had to be some way to guide your energy through your body. After thinking that way, they quickly recovered from their initial shock.
But for Atrog it was no surprise, as a Troll, which are not genetically gifted for ki usage, trained and used his unusual intelligence, to find those pathways and control his ki. Broly on the other hand was somewhat aware of meridians through his past life experience, he remembered reading novels about those kinds of cultivators.
They learned that using ki for many races is a difficult thing, having to train arduously to be able to use it throughout the body, hence most aren't even aware of them and are using cannons to fight.
The city lord went on with how to meditate to increase their ki and gain a feel for the meridians. It wasn't long before the lesson was over, and the kids were in deep thoughts. The city lord told them that they had to study their meridians on their own, since every person and race was a bit different. They would just need to circulate their ki throughout the body and try to feel the pathways. They needed to develop an inner eye. By learning where exactly the meridians are, coupled with their natural affinity to it, they would gain a much higher degree of control. This would allow them to learn techniques even faster.
The second point in this lesson was like a wake-up call for Broly. The city lord reminded them, to train their body to be at least on par with the ki, they accumulated. By training their body they could increase their ki, since the body is essential a vessel for it. If they only meditate, it would fill their body to the brim and they would be stuck at that level for some time. Ki has an ability to strengthen your body to a degree and with time your body would be able to handle more ki.
But meditation coupled with physical training the strengthening process would accelerate by many times. So, they were advised to balance their training, as it would be the fastest way to increase their overall strength.
When Broly heard that, he decided to ask some question after the lesson to clarify some thoughts he had. After the others went to the training rooms Broly went up to the city lord and asked.
"Can some people automatically accumulate ki without meditation?"
"Oh, you have questions? Let me think. Hmmm. Not that I have heard of. After most reach adulthood they have a consistent level of ki, if they don't use it. But using ki in battle for example strains the body. Over time the body adapts to the usage and their ki reserves increases. That's how most increase their ki and strength. But just by using it, the ki in the body only grows slowly.
Therefore, it is clever to meditate to increase your ki and then use it in battle or train your body to adapt to this new power."
'As I thought that somewhat explains the Zenkai Boost. As it was said in the series, the body will imprint on the injuries. After having survived a lethal wound, the body strengthens to the point it could receive the same attack which caused the wound. Therefore, automatically increasing the upper limit of ki they can store, and the Senzu Bean just filled Goku and the rest up with energy.'
"What happens if the ki constantly increases to the point it would overflow?"
"Overflow? Before overflowing it would probably go rampage in the body, trying to reach every part of your body. It would mess with your head until it destroys all your organs. Ki has strengthening properties but too much would just destroy the cells as they wouldn't be able to hold the energy. Essentially bursting out of the cells until it would overflow to the surroundings.
You would need to quickly use up the excessive energy, which would defuse the problem for a moment, but to solve it, you would still have to excessively train your body to offset the imbalance."
'F*ck me! That's why Broly in the series was such a maniac! Having his ki suppressed probably messed with his brain as his ki still grew but couldn't release it unless Paragus let him.'
"Are there any techniques for body strengthening?"
Since the questions pointed to the same thing, it dawned to the city lord why Broly asked him all those questions. A 3-year-old winning a tournament against other races, most of them 5 years older than him, it should be obvious that his body was unique.
"Broly you probably realized after I told you, how dangerous that kind of body type is. We need to do something the earlier the better. I have a feeling that only strengthening your body wouldn't be enough. Come here for a second. I will envelop you with my ki and try to sense your ki as best as I can. I have to get a better understanding of your ki before I can help you."
Broly knew he wouldn't be able to solve this easily on his own. The city lord was the best in controlling ki. With his experience he would be able to help Broly understand his situation better, maybe even solve his predicament.
"Alright. I will be in your care."
The city lord enveloped Broly with his bluish aura. "Alright stop suppressing your power."
After Broly stopped his suppression, the city lord could clearly feel Broly's ki. "Now power up to your fullest!"
Broly's ki instantly flared up, pushing the ki of the city lord outward. For 10 minutes the city lord asked Broly to control his ki in different ways. The more the city lord observed the worse his face became.
"Alright, that's enough."
"So, how is it?"
