Tianjin Fan didn't expect Dr. Brieves to be so easy to speak, it seems that his previous worries were superfluous, after all, the doctor is an adult, and he will not be as willful as a girl like Bulma, so why refuse on the grounds of "I'm still busy dating, I don't have time to help you research this and that". Pen ~ fun ~ pavilion www.biquge.info

"I've got some devices that I want the doctor to build for me. I heard that Ph.D., you are very proficient in space? Tianjin Fan asked.

"Huh? I'm proficient in the energy side. The doctor gave him a strange look, "It seems that you don't know much about my research direction." ”

"Huh? Isn't the principle of the capsule to compress space and shorten the distance between atoms and molecules to achieve the effect of shrinking? Tianjin Fan touched his nose in embarrassment. In my previous life, when I was exposed to physical chemistry in junior high school, I had a whim, maybe the capsule was made by using the huge gap between atoms, right?

"Hahaha~!" The Doctor let out a loud laugh, "Indeed, a lot of people think so. But no, I'm using the principle of energy conversion. ”

Tianjin Fan was aroused by curiosity, and couldn't help but ask the doctor: "Why?" Isn't it a space compression technique to hold such a huge object in a capsule? No matter how much energy is converted, it is impossible to achieve such an effect, right? ”

"It's not what you think. When I first started researching, I also planned to use the principle of spatial compression to make convenient capsules. But I found that if that's the case, the amount of energy required is very large, and it may be easy for gases to reduce the distance between atoms, but it will be very difficult for many solids and even metals, and it will require too much external energy to exert pressure. It simply can't be made into a convenient and portable capsule; The second is that even if an object is compressed and reduced to the size of a capsule, its own mass does not change, but because of the increase in density, a small capsule will have a lot of weight. Imagine that if you hold a car in the capsule in your hand, then you are equivalent to lifting a car in the air with your bare hands, how can a normal person have such strength. So I ended up concluding that the method of spatial compression basically doesn't work. The doctor said, gesturing his hands.

"So later, I turned to the energy aspect. Because energy is not massive. If I can work out a principle for transforming matter and energy, and create a device that instantly converts a house into a kind of energy for storage, then even an old man can easily grab the capsule. ”

Tianjin Fan imagined it for a while, but he really couldn't imagine what kind of device could achieve the function of converting matter and energy into each other at will, and suddenly felt that the Dragon Ball world was worthy of being a world of miracles, and such incredible things could be invented.

Tianjin Fan is not a scientist, so he does not bother with the principle of capsules. However, it would be even better if the doctor was proficient in energy, and it is no wonder that Dr. Brieves was able to develop a hypergravity chamber in the original book, so he directly put forward his own idea: "In fact, the device I want to make is also related to energy and matter. I want to make a room where you can adjust gravity at will, and I don't know much about that, but I think you should be able to complete this device, right? ”

Dr. Brieves groaned.

"If you can use energy to create something like a black hole, then you should be able to generate extremely strong gravity, right?" Tianjin Fan said his own thoughts.

A strange look appeared in the doctor's eyes: "If the principle of capsule making is to convert - matter into energy and store it - then it seems feasible to convert energy into matter and increase the gravitational force of objects. Well, the study is interesting, and I think I should be able to achieve it. But what are you building this kind of room for? Such a room is of no use at all, is it? ”

"I want to work out in hypergravity. When I was cultivating in a place with four times the gravity, my strength increased quite quickly, but recently the growth rate of my strength has slowed down. Whether it's weight-bearing or quadruple gravity, it's no longer enough for me to cultivate. So I'm hoping to make a higher multiplier of the Hypergravity Room so that it can help me improve my strength. Tianjin Fan said quietly.

"Is that so? You martial artists are really hardworking, obviously you are already so powerful, but you still want to keep improving yourself. The doctor said with emotion, and glanced at Yamucha thoughtfully. It seems that martial artists are indeed a group of guys who just want to get stronger.

"Gravity? You can actually think of improving your strength through this, what an imaginative martial artist. I'm curious how powerful you really are right now. Yamucha's eyes flashed with a flame called battle intent: "I feel like I can't wait for the martial arts meeting anymore, I want to compete with you now!" ”

"Really?" Tianjin Fan looked at Yamu tea.

The short hair stood up in the sky, with a hint of grandeur rooted in his nature, and it seemed that the psychological wound from the last time had been completely repaired; Even at home, he was wearing a martial arts uniform of the Turtle Immortal Stream, and he seemed to be preparing to cultivate all the time; On the resolute face, a scar ran from the center of his forehead to his right eye, and slashed diagonally to the right cheek, showing that he had not only buried his head in hard training in the past three years, but also experienced many dangerous situations.

"Then let's fight!" Tianjin Fan may not have fought with anyone for a long time, and looking at the opponent in front of him, he suddenly felt his blood churning.

"Can you fly?"

"Hmph." As if feeling underestimated, Yamucha flew directly towards the outside of the house.

Tianjin Fan said hello to everyone, and also flew to the suburbs outside the city with Yamucha.

Although the Bulma family also has a practice room specially prepared for Yamucha, after all, it is only prepared for ordinary exercise, and if there is a fierce battle, it is obviously not enough to withstand the strength of the two.

"Really, I obviously said that I was going to go shopping together, and I just came back, so I went to fight with people again." Bulma said to Lan Luo depressedly.

"Ha~! Man! Fighting is their romance~! Lan Luo said with a fluttering eyebrow.

Bulma covered her face with a depressed face: "Alas, why do all the people I know are such battle maniacs......" Think about Goku, who I met at the beginning, and later my lover Yamucha, and Klin, all of whom are guys who like to fight. Of course, she didn't know it at this time, and in the end, the person she married was a prince who lived entirely in battle.

The doctor was smoking a cigarette in the cab, holding the steering wheel with one hand, holding the back of the chair with the other, and turned back to Bulma and said, "Actually, I'm also quite curious, what kind of people have to be to be so powerful that they can conquer the royal capital by ignoring the army?" If Tianjin Rice can destroy such a demon king, how powerful should it be? ”

"Haha! Look at it, old man, my Ah Tian is the strongest human being! Lan Luo looked proud.

"Huh!" The airship landed on the gravel ground by the river, making an exhaust sound. Docked steadily, the group walked out and looked at the two people standing in the distance.

"It's here~" Tianjin Fan waved his hand and turned his head to smile at the people by the river.

Yamucha also raised her hand to signal, but her eyes were still fixed on Tianjin Rice, and the flames in her eyes were burning brighter and brighter.

"I didn't expect you to learn the Sky Dance Technique." Tianjin Fan looked at Yamucha and said with interest. The Yamucha in front of him has a calm momentum, and in his opinion, he is already a rare opponent.

Compared to the Yamucha who had not seen the Great Demon King of Bick in the original book, he was already much stronger at this time. After all, he is a man who wants to become a martial artist, and after encountering such a setback, once he regains his fighting spirit, he is full of desire to improve his strength, so he has not wasted it at all in the past three years, and has been practicing all over the world.

The two bowed and saluted, each assuming a posture to meet the enemy.

Feeling the momentum of the man in front of him, Yamucha was awe-inspiring in his heart. His strength has long been different from what it used to be, but in front of this person, he still doesn't feel any flaws. However, if there is no flaw, will you not make a move?

If there is no flaw, then there is a flaw!

Yamucha took the lead.

As soon as he made a move, it was the wolf tooth wind fist that he was proud of.

The claw shadow in the sky tore all the air in front of him, and the chaotic air current, with his high-speed running, attacked Tianjin Rice together.

Tianjin Fan is not in a hurry, no matter how fast the fist speed is, if it does not have the matching movement speed, it is impossible to hit himself at all.

His right foot was a little on the ground, like a fallen leaf, falling to the left. Then he stepped on the ground with his left foot, like a squeezed spring, and bounced back to punch Yamucha at a faster speed.

Yamucha smiled confidently. I understand that close range is the best distance for the Wolf Tooth Wind Fist, and I use this most powerful move, just to force the other party to make a move in front of the close, as long as there is a move, there will be a flaw, such as at this moment!

The shadow of the claws in the sky vanished.

The right fist accurately grabbed the punch that came from Tianjin Rice. The left fist clenched and struck him in the abdomen.

Tianjin Fan grinned, flicked his legs on the ground, instantly turned over and rose into the air, and jumped upside down to the top of Yamucha's head. The tightly grasped fist twisted, and instantly held Yamucha's wrist with the other hand, and with a strong back, he shook it violently, throwing Yamucha away.

Then he fell heavily to the ground, squatted down with his legs, his right fist and left palm against each other, his right elbow was like a sharp arrow, and the whole person popped out like a sharp arrow, crashing into the air blocking him, and shooting towards Yamucha who was in mid-air.

Yamucha rolled in the air and controlled her body, but her back was in the direction of Tianjin Fan, as if she didn't notice his attack.

Suddenly, the blue light lit up, and as Yamucha turned around, the light became more and more dazzling, and the blue light cluster was already in Yamucha's arms.

"Wave!"

As Yamucha drank softly, a blue qigong wave erupted.

With such a close distance, Tianjin Rice seems to be unable to react.

But I didn't expect that the qigong wave seemed to pass through the body of Tianjin Rice, but it was like penetrating the air, and it did not have the effect of life, but flew straight towards the river.

A huge amount of water rushed into the sky, and with the explosion, it splashed in all directions, turning into a flood of water droplets, and the water droplets fell like a heavy rain.

The doctor and the others standing by the river were drenched.

"Bastard Yamucha! You almost on us, you know!? Bulma was taken aback, just now he thought that the qigong wave would directly hit him and the others, and at this time he roared at Yamucha with his teeth and claws.

Half of the cigarette fell to the ground, and the doctor was stunned to look at the two figures in the distance, and then looked at the huge pit at the bottom of the river behind him, and finally saw the power of the martial artist for the first time.

"What an unscientific power, a mortal can actually grasp such a ferocious energy on his own." The Doctor exclaimed.

"Come on! Ah Tian! Lan Luo waved her right hand to cheer up her sweetheart: "If you kill him, I will never call you sweetheart again!" ”

Even in the midst of the fierce fight, a drop of sweat clearly appeared on Tianjin Fan's forehead. This mother-in-law actually shouted her most hated name in front of outsiders.

However, it seems that this word will never be heard again. Because, defeating the person in front of you is simply an inevitable end, but I don't know how much strength I have to use.
