After Zhuge Liang accompanied Liu Chan to live in Jixia Academy, he visited many of his senior brothers and sisters and praised their achievements. Zhuge Liang especially loves Sun Bin's time shuttle, and discusses various issues related to time travel with Sun Bin every day.

"Senior brother, although your time shuttle can only travel to the future at present, I believe that in the near future, you will definitely be able to travel to the past, and then meet the people you want to meet and do the things you want to change." Zhuge Liang encouraged Sun Bin Dao.

"Thank you for Brother Kong Ming's encouragement, if you want to travel to the past, then you will have higher requirements for equipment. But then again, even if you do travel to the past, if you change something in the past, how does that affect the present? Maybe it's bad, maybe it's good, or maybe it doesn't have any effect. Therefore, before understanding the impact, we should be cautious and think twice. Sun Bin said.

"Senior brother, what you said is not unreasonable, there are indeed too many uncertain factors in this. But we can infer this by comparing analogies. For example, every time you travel back into the future and come back, carefully record and compare the subtle changes that have occurred around you before and after the crossing. If it really has a bad impact on the present, then we really have to think twice about traveling to the past. Zhuge Liang said.

"Senior brother, what I said is that it is indeed the best way to predict the impact of records and then re-compare." Sun Bin said.

"This is just a shallow idea of the senior brother, I hope the junior brother will consider it." Zhuge Liang waved his feather fan and replied with a smile.

Liu Chan was extremely curious about everything in Jixia Academy, and he found that everyone had their own inventions and unique skills. He was especially obsessed with Master Luban's invention. Lu Ban had been improving his new invention and had no time to talk to Liu Chan, while Lian Po had nothing to do, so he acted as his commentator.

From the flying wings of the organs, aircraft carriers, thunderbolts, giant bird guns, to the Yuanqi cannons, human-powered aircraft, and the mechanical armor that Lu Ban is working on, they all explained to Liu Chan one by one, and Liu Chan listened with relish, and paid full attention.

"Master Lian Po, can you tell me more details, what is Master Luban's mechanical armor, do you know, this time I came to your academy, I also brought my own mechanical armor, it was jointly created by my father and me, a armor that can go to the front line to kill the enemy." Liu Chan said.

"What kind of powerplant are yours?" Lian Po asked.

"It's a spring-loaded way of accumulating energy, and I have to work hard to tighten the spring before each use." Liu Chan said.

"My junior brother Luban's mechanical armor is completely controlled by electricity, there is no need to wind it, people wear it to walk, walk like flying, and the power is so great that it can lift something weighing a thousand catties." Lian Po said.

"Really, when will I see you?" Liu Chan asked expectantly.

"I have to wait for two days, when my junior brother Lu Ban is studying things, he is most annoyed that others will disturb him. Every time my sister brings him food, she always puts it at the door and leaves. Lian Po said.

"Master Lian Po, where has Master Luban studied now?" Liu Chan asked.

"He's now installing a Thunderbolt on the Mech, which will greatly increase the destructive power of the Mech." Lian Po said.

"Then Master Lianpo, what is your most powerful invention?" Liu Chan suddenly asked.

Liu Chan's question really stopped Lian Po, after all, Lian Po didn't like to calm down and invent something.

"Just invent these little things and leave them to the juniors and disciples. As their elder brother, of course, I am more focused on improving my own cultivation, and I can show you that. Lian Po said calmly.

Liu Chan was puzzled, and followed Lian Po to a corner of the academy grounds, Liu Chan saw that Lian Po walked in front of a pile of boulders, lifted a boulder, and then threw it high into the air, just when the boulder fell down, Lian Po clenched his fists and directly hugged the boulder in front of his chest, and in an instant, the boulder split apart and scattered all over the ground.

Immediately afterwards, Lian Po kicked his legs again and again, kicking several boulders nearby beside him with all his might, and kicked them into the air one by one. Just as the boulder fell to the same height as Lian Po's chest, he saw Lian Po roar, and the air was shaken by the true qi, and then several boulders around him were shattered again and again and scattered around him.

When Liu Chan saw the scene in front of him, he almost dropped his jaw in shock, ran to Lian Po's body, and kept looking around to see what was wrong with Lian Po's body, which could easily shatter the boulder.

"Master Lian Po, is your body an impregnable wall, it is so hard to the touch, I feel that my armor can be shattered by your punch, what was that move you just had, can you teach me?" Liu Chan cast an envious glance at Lian Po.

"This trick is my housekeeping stunt, it's called justice bombardment, it's not something you can practice casually, I have practiced this trick for ten years. Not only that, but ordinary swords have no effect on me at all. Lian Po said complacently.

"Ten years? Forget it, I don't have the perseverance to memorize the articles written by the military advisor, let alone practice one of your tricks for ten years. When Liu Chan heard this, Fang Cai's impulse suddenly cooled.

"Haha, in this world, there is no such thing as a free lunch. If a person doesn't work hard, then he can't do the best in everything, what do you say? Lian Po said.

"Master Lian Po taught me that when I find something that suits me, I will definitely work hard to persevere." Liu Chan is a serious way.

"Well, that's good." Lian Po nodded and patted Liu Chan on the shoulder.

"Then let's go to Master Luban and have a look, maybe he has come out of the house." Liu Chan said.

"Okay, let's go. Continuing with the topic just now, before you work hard, you have to eat yourself a little fatter, understand, see you're about to lose weight like a monkey, how can you have any strength to wear a mechanical armor. Lian Po wrapped his arms around the short Liu Chan's shoulders, looked Liu Chan up and down, and teased him with a smile.

"My appetite has been getting worse and worse since my father's death, but when I get to the land of Jixia, I feel that my appetite has grown a lot." Liu Chan said.

It seems that this child is also a poor person, the country is ruined and the family is dead, and the wind and rain are shaking the rivers and lakes, and Lian Po is worried.

When the two of them chatted and walked back to the Luban experimental base, they happened to meet Luban coming out of the experimental base.

"Senior brother, I just wanted to find you." Luban Road.

"Are you hungry? I'll ask your sister to cook for you. Lian Po asked.

"No, I've already installed the Thunderbolt Armor, and I want you to help me put it on." Luban Road.

When Lian Po heard this, he was overjoyed and said with a smile: "Senior brother, you have been researching and modifying all morning, and you have been working very hard, and you haven't eaten lunch, and there are more suitable candidates than you for the trial armor." ”

Lu Ban frowned slightly and asked, "Who?" I really want to take a break, my arms are so sore that I can't lift them now. ”

"Hehe, this person is far away in the sky, close in front of him." Lian Po deliberately sold Guan Zidao.

"You? But your physique can't fit it. Lu Ban mistakenly thought that Lian Po was talking about himself.

"Your senior brother and I are invulnerable, do you need any battle armor, I mean Liu Chan, he himself has a set of battle armor, he has a certain level of proficiency in the operation of the mechanical battle armor, and he is thin, he can wear your battle armor, what do you think of him?" Lian Po asked.

"That's great, I just don't know Liu Chan, do you agree?" Lu Ban asked Liu Chan.

"Master Luban, I have heard of your reputation for a long time, and the battle armor you personally built, of course I am willing to give it a try." Liu Chan learned the tone of an adult and replied respectfully.

"Okay, that's it." Lu Ban was pleased.

"Hey, you kid, you will also pretend to be a hypocrisy, sycophants, I knew you were a flatterer, I shouldn't have helped you, let you beg someone to go." Lian Po joked at Liu Chandao.

When Liu Chan heard this, he touched the back of his head and smiled awkwardly.

Then, the three of them walked into the experimental base, Lian Po and Lu Ban helped Liu Chan put on this, and Lu Ban spent a long time to create the power mechanical battle armor.

The muddy body of the mechanical armor is glowing with silver phosphorescence, and every subtle concave surface is personally created by Lu Ban Quenching, and there is a kinetic energy conversion device inside the armor, which will store the acidic pool tank full of electricity, miniaturized into blocks, and spread all over the non-stressed parts of the mecha, and the kinetic energy generated by the mecha's own movement will also be converted into electrical energy to a certain extent, stored in the acidic tank, so that the lasting combat effectiveness of the mechanical armor will be extraordinary.

The limbs of the mecha also have the function of energy storage, when the limbs swing, it will convert the torque force into the energy storage of spring compression through the gears, that is, every once in a while, the mecha will trigger a gravity strike, which is more than 5 times the power of an ordinary blow. In terms of protecting the user, the part of the mecha that comes into contact with people is made of several layers of rhinoceros leather stitched together, and the outer layer of the rhinoceros leather and the outer layer of the mecha are connected by a large number of fine buffer springs, which will greatly reduce the impact caused by external forces when the user encounters an external attack or unfortunately falls to the ground.

On the left arm of the Mecha, there is a Thunderbolt Shell and a red trigger device on the wrist joint, which can be used when facing powerful enemies or chasing them.

When Liu Chan put on this mechanical battle armor specially designed for battle, Liu Chan's face was full of glory, although the mechanical battle armor was heavy, but when Liu Chan walked, he did not feel the slightest feeling of weight. Jumping on the spot can easily jump onto the three-meter-high courtyard wall, and the speed of the fast run can be comparable to that of a cheetah. A normal punch can easily shatter a 30-centimeter-thick boulder, and when a heavy blow is triggered, five stacked 30-centimeter-thick boulders can be completely shattered.

When Lu Ban informed Liu Chan of the specific operation knowledge and skills, Liu Chan quickly mastered and skillfully used them.

"Senior brother, your mechanical armor is simply specially created for Liu Chan." Lian Po sighed with emotion after seeing Liu Chan's near-perfect control.

"Yes, senior brother, I didn't expect him to master the control skills so quickly." Lu Ban agreed with him.

"By the way, junior brother, I don't know how strong your armor is, I still remember the armor of the Jarda, after the sword, there was no scar left." Lian Po said.

"The armor that Liu Chan is wearing now is made of Erda armor." Lu Ban said calmly.

Lian Po couldn't believe his ears, and he turned sideways and asked, "Then how did you cut their armor?" ”

"It's not a cut, I'm using the flame hedron I picked up from the volcano to melt the armor and rebuild it." Luban explained.

"Flame Crystal?"

"Well, this is the idea that Mr. Master helped me come up with." Luban Road.

"I really didn't expect to be able to melt their armor on our planet." Lian Po sighed.

"Senior brother, after all, the brine points tofu, is it a thing to drop a thing?" Luban Road.

The next day, Liu Chan showed the mechanical armor to others to watch, and when Guan Yu and Zhang Fei saw it, they shouted and cheered for it again and again.

"Third brother, Chan'er has really grown this time, he can operate such a complex battle armor designed by Master Lu Ban so well, if the eldest brother knows about it, he will definitely be very happy." Guan Yu said with a lot of emotion.

"Yes, if I had known this, the military advisor should have brought him here earlier." Zhang Fei said.

"I thought that Jixia Academy would not treat us very well, but I didn't expect... I was narrow-minded at first. Guan Yu said.

"Second brother, don't talk about it, look at Zen'er, not only can you break thousands of pounds of heavy stones with one punch, but you can also fly on the roof and walk on the wall." Zhang Fei pulled Guan Yu's arm and said hurriedly.

"The mechanical armor looks like it weighs hundreds of pounds, and it can walk like a fly on the roof, and the tiles will not be broken because of this, not only must it be fast enough, but it also has high requirements for the grasp of the center of gravity, well, good, good." Guan Yu praised again and again.
