'Qi' [Semi-analytical chapter, feel free to skip if you dislike it]

Ki was a concept in the world of Dragon Balls.

Based on the information Son Gohan had browsed through on various forums in his previous life, combined with his own analysis and reflection, he had summed up a rough idea of it.

Many people who had just started watching Dragon Balls would think that ki was proof of whether one's energy was powerful or not. In truth, that was not correct.

First, to use the simplest example, androids possessed enormous energy, but Son Goku and the others could not sense any ki from them at all.

But some people might ask, Cell was also an android, so why could they sense ki from him?

First of all, this was another misunderstanding people fell into when they did not watch the plot carefully. Cell was an android, but if one paid attention to the plot, one would discover that this guy was born from an egg.

For that, one could look at the giant eggshell in Trunks's time machine during the Android Saga.

Android 17 and Android 18 were actually living human beings who had been modified, so the existence of ki could not be felt from them.

Therefore, ki was not equal to the strength of energy, but if ki was powerful, then the energy inside the body would basically be very strong.

Ki was actually a form of expression created from the combination of a living being's physical body, energy, spirit, and so on.

Since childhood, Son Goku had trained his body under the Son Gohan who found him, and while training under Master Roshi, he had also awakened the ki inside his body.

Master Roshi had taught them how to use ki, and they had learned things like flying by controlling ki.

In the world of Dragon Balls, if ordinary people wanted to awaken the ki inside their bodies and then use it, it was extremely difficult.

Perhaps many people would say, why could Krillin, Yamcha, Tien Shinhan, and the others all use ki?

But had anyone ever thought about how many humans there were on Earth in the world of Dragon Balls, and how many martial artists there were?

Just taking those who had participated in the past World Martial Arts Tournaments, how many of them could use ki?

Ki might actually be vitally important in the world of Dragon Balls.

Ki could also serve as a means to lock onto a target. Son Goku had relied on locking onto ki, combined with Instant Transmission, to travel through all the places in the universe where he could lock onto the aura of life.

At the same time, as one of Goku's ultimate techniques, the Spirit Bomb allowed all life in the universe to share its ki, combining it into an ultimate move capable of destroying evil villains.

Therefore, comprehending ki, using ki, controlling ki, and fusing ki were all vitally important to Son Gohan.

However, Son Gohan was not worried at all. The Saiyan physique determined that they could awaken the ki inside their bodies very early on, and could even use it very skillfully.

Sure enough, in his battle with Mr. Popo, Son Gohan directly awakened and erupted with ki.

The ki eruption greatly enhanced Son Gohan's combat power. He was not surprised by this, because this was the activation of the energy contained within his cells.

The Saiyans' unique S-Cells (I understood it as SUPER, and would refer to them collectively as Super Cells from now on) gave them a starting point far higher than Earthlings, and the ki they were naturally capable of containing and awakening was also not something ordinary humans could compare to.

Back to the point, in short, as long as he awakened ki, it meant Son Gohan had already stepped onto a fast track to becoming stronger.

He decisively took out half a Senzu Bean from his chest and tossed it into his mouth, chewing it up and swallowing it amid a crunch.

The next moment, Son Gohan immediately felt his previous exhaustion vanish completely, and a sense of fullness spread throughout his entire body.

Phew~!

Son Gohan slowly let out a breath and looked at Mr. Popo again. The intense battle intent in his eyes was already extremely obvious.

Mr. Popo would not refuse either. He, who did not seem to know fatigue at all, was very willing to help Son Gohan improve his strength.

Five days later, Son Goku rode the Flying Nimbus to Karin's place, only to be told that Son Gohan had already been sent to God.

But when Son Goku arrived at Kami's Lookout, he saw Son Gohan engaged in an intense battle with Mr. Popo.

Yet none of that was what shocked him the most. What surprised Son Goku the most was the ki on Son Gohan's body, which was on a completely different level from before.

In fact, before he had arrived at Kami's Lookout, Son Goku had already sensed this ki. It had felt very familiar, but he had never expected it to be his son's ki.

This ki had even already surpassed that of his good friend Krillin. It truly made Son Goku find it a little hard to believe, but in the end, seeing was believing.

"Dad." Seeing Son Goku, Son Gohan stopped his rhythm of attack.

"You..." For a moment, Son Goku did not know how to ask.

"This is all thanks to Mr. Popo. Under his training, my combat power has improved by leaps and bounds!" Son Gohan said truthfully.

"This is not entirely Popo's credit. Mr. Gohan's progress was very fast as well," Mr. Popo said.

"All right, looks like Gohan's talent is really high." Son Goku scratched his head and laughed heartily.

He was simply that pure. After all, his son's strength improving by leaps and bounds was not a bad thing. On the contrary, it made Son Goku extremely happy.

"Goku." Just then, God suddenly spoke up and called out.

"God." Goku immediately turned around and responded.

"It seems your son did not tell you about that matter," God said, looking at Son Goku's expression and instantly judging that much.

"What matter?" Looking at God's grave expression, the smile on Goku's face also disappeared.

"Dad, I had a dream that not long from now, an evil alien will come to Earth and destroy things everywhere!" Son Gohan immediately said.

Hearing this, God's eyes moved slightly, but he did not speak.

"This might only be a dream, but why would you take it seriously, God?" Son Goku asked again.

Even if God were a fool, he knew that Son Gohan had kicked the ball to him. After all, having it come from his mouth and having Gohan say it himself were two different concepts.

Helpless, Kami could only say, "Last night, I also sensed an evil presence heading toward Earth, so that might not have been just a dream."

"He's strong?" Son Goku asked, his eyes narrowing.

Son Gohan thought it over, and in the end decided to speak. "I dreamed that he defeated both Piccolo and you, Father. And at the end, I even dreamed that you and he died together!"

"What!?" This time, even Kami was shocked.

Everyone present knew Piccolo's strength. Even the current Son Goku could not say for certain that he could defeat him. But if the two of them joined forces, they could only take the enemy down with them?

"But there isn't enough time now," Son Goku said helplessly.

He did not blame Son Gohan for not saying it sooner, because if not for Kami's corroboration, he would at most have taken it as nothing more than one of Son Gohan's nightmares.

"No, you have enough time!" Kami's slightly hoarse voice rang out.

"What do you mean?" Son Goku asked, puzzled.

"Goku, do you still remember the place you entered when you were a child?" Kami raised his staff and pointed in one direction of Kami's Lookout.

Son Goku looked in the direction he indicated. After thinking for two seconds at first, his eyes immediately widened. "You can't mean that place called the Hyperbolic Time Chamber, can you!?"

Kami lowered his staff and nodded. "That's right. Right now, only that place can give you enough time."
