After staying at Mutants Academy for three days, Rick and his younger brother Professor X said goodbye, took Liu Li to the air and flew towards Kama Taj.

You need to ask Liu Li to go back to learn magic and read more magic books.

Rick himself actually doesn't want to stay in Mutants Academy for too long. Although Professor X is here, once the mutant-related plot is triggered, it makes the copy of Doctor Strange, which is already difficult to pass, more complicated.

A few hours later, Rick and Liu Li returned to Kama Taj.

That night, I had a meal with the mages of Kama Taj.

After living in Mutants Academy for a few days, now I go back to Kama Taj. Although Kama Taj's food has improved compared to before, both Reek and Liu Li have not had much appetite.

The living standards here are poor.

So Liu Li returned to Kama Taj and didn't mainly want to eat, so she began to study the many magic books in Kama Taj's library.

As for Rick, he still practices his sword every day with a mahogany sword in Kamataj's magic training ground.

On the morning of the third day, Rick was practicing swords, and the bald Ancient Master came over.

"You practice swords in my magic practice place every day. Those who don't know think you are here to make trouble. Other disciples are secretly paying attention to you, the person who practices wooden swords." Gu Yi said helplessly.

"There's no way. I want to learn your spells, but unfortunately I can't learn them. Your spells are too difficult. Otherwise, you can teach me some simple and easy-to-get-hand spells alone." Rick said, temporarily retracting the wooden sword, preparing to rest, and waiting for Gu Yi to leave before practicing.

"Did you go to find a helper a few days ago? How about it? Are you confident in dealing with the Domamu brother and sister? Are you going to fight against Domamu or his sister at that time?" Gu Yi asked.

"I'll be responsible for dealing with Domaum. Domaum's sister Oma left for Strange." Rick said after thinking about it.

After all, I have read the form and some attack moves in the original work, and I have some understanding of them.

As for Dormam's sister Oma, Rick knows exactly what kind of attack method and strength it is.

That unknown enemy, Oma, is left to Doctor Strange who possesses the time gem.

Anyway, Doctor Strange can create a closed loop of time, and when the time is reset infinitely, he will not die.

Moreover, Doctor Strange went to talk about conditions with Domaum's sister Oma. Maybe the two of them could fall in love with each other. If they could become partners, it would be a great blessing.

Rick thought that his fellow disciples could have found a reliable home for Dr. Qiyi.

"Rick, what are you laughing at? Are you thinking of something good?" Gu Yi, the bald man beside him, asked.

Rick was brought back to reality by Gu Yi's question and no longer wanted to find a girlfriend for Dr. Qiyi.

"Nothing! Master Gu Yi, can you teach me magic?" Rick said.

Exchange good books and follow the vx official account. [Book Friends Base Camp]. Follow now and you can receive cash red envelopes!

"You are not suitable for learning, and teaching you is just a waste of our time, you can't learn it." Gu Yi said.

"Then what did you accept me for your disciples before?" Rick asked back.

When Gu Yi heard Rick's words, he became angry, "You have to join me. Think about what you did before you become a disciple!"

Rick thought about it and it seemed that it was true. He came to find Gu Yi on his own initiative.

However, the first stage of the main mission of Zhutian Online was required to join Strange in the ancient sect, and it would not be possible to complete it.

"I have worshipped my disciples. I can't learn magic. Please find me some powerful magic jewelry. There should be a lot of collections in your wizard school." Rick tried to ask, stretching out his left hand to ask Gu Yi for something.

"No, your collection in the Heavenly Palace is no less than mine!" Gu Yi refused directly, and then quickly turned around and left.

This bald Gu Yi was too stingy, Rick thought.

When Strange is in charge of the family in the future, ask Dr. Strange for it yourself.

After Gu Yi left, Rick continued to practice swordsmanship.

The sword-controlling technique is profound and profound, and there are many sword-making moves. Rick has only mastered his sword moves these days, but he is far from being able to master the ability to use them at will.

Just one sword can have power, but if you want to use half of your sword move, Rick can't do it.

As for the flying sword, the level of sword control is still too low and cannot be used.

Relying on one's own understanding and practicing sword control skills slowly, Rick probably won't be able to perform sword control flights in decades, and it would be good if the Ten Thousand Swords Art is there.

Fortunately, this sword-controlling technique can be upgraded and stronger as long as it kills the enemy.

Become a player online in the world, powerful enemies will not be lacking, and Rick is in no hurry to find an opponent to kill.

Continue to practice the basic sword moves of sword control and lay a solid foundation for yourself.

Even after upgrading the sword-controlling skills, at the same level, the player's sword-controlling realm and understanding of moves are different, and the power of the sword-controlling skills he uses is also a huge difference.

Rick knew the late power of sword-controlling techniques. Now the ordinary sword-controlling techniques are worthy of his energy to practice.

Time passed day by day, and Rick practiced in Kamataj for more than a month, which was quite leisurely.

Today, Lake received a call from Tony. The design drawings and modeling of the Black Technology Great Wall rail gun have been completed, and he needs to go there.

That night, Rick controlled the Iron Man armor again, and accelerated with the Thor's hammer, and flew to Tony's laboratory.

During the experiment, a long metal pipe was modified on a virtual three-dimensional display screen and an animation modeling surround the Great Wall in the Asian region.

This pipeline is the shell acceleration tube of the Black Technology Great Wall rail gun.

And I walked around the Great Wall, and the starting point and the ending position were very close.

The pipe terminates, and is raised towards the air, like a circular missile launch silo.

This Great Wall rail gun barrel has a total of thirteen special devices for accelerating shells.

"There are detailed design drawings of the Great Wall rail gun in this USB disk. This Great Wall is modeled around the Asian region according to your description. Even if the Great Wall location is changed, it doesn't matter, the track can be fine-tuned. Now I will tell you the most critical point of the Great Wall rail gun being able to fire. How do you concretely change the laws of physics to improve energy conversion. Simply put, you need to charge the Great Wall rail gun and fire the gun." Tony said.

Rick nodded, thinking it was quite simple.

Tony, on an electronic screen, began to tell Rick the process of using realistic gems to change the laws of physics and convert energy.

After listening to it, it was like a book of heaven. It was like a bunch of physical symbols and laws. I had heard of the names myself, but I didn't know the meaning at all.

It seems a bit difficult to use realistic gems to convert energy and change these physical laws and laws...

"It's very simple. I've finished talking, and there is nothing I don't know!" Tony turned around and asked Rick after ten minutes of speaking.

Rick smiled, "It's the one who reduces friction!"

"I don't understand this one, you have a good understanding. I'll tell you about the effect of reducing friction, which can accelerate the shells faster. This is very simple!" Tony said.

Rick waved his hand, "No, I understand the need to reduce friction. I don't understand anything else you said, such as magnetic fields, entropy changes, quarks, etc." Rick said truthfully.

Hearing Lake's words, Tony looked at Lake in a daze.

"How much do you have in technology?" Tony asked Rick.

"According to your world, it seems like a university!" Rekto said a little. In fact, he had not graduated from university yet.

And I am not a major in advanced physics and energy mechanics.

After listening to Lake's answer, Tony felt it was difficult.

"Forget it, wait for me for a few minutes, I'll think about it, and think of it for you to have a simpler and quick result." Tony closed his eyes and began to think quickly.

Rick heard that there was a quick success, this one was great!

This Iron Man Tony is indeed very powerful, and he has to do it quickly. He has learned it for too long and he can't remember it.

A few minutes later, Tony opened his eyes, "Okay, I thought it was too complicated before, and I had a high expectation from you. In fact, you have a realistic gem, so don't think about the process. Just think about the result, you skip the transformation process of the energy of the laws of physics. As long as you think about it, you fire the gun and take one shot, the shell will accelerate in the Great Wall rail gun, and the speed of the shell will reach a rapid speed, which you can understand, exceeds the speed of light. Because the shell speed is too fast, the shell will enter subspace, the shell will disappear in the atmosphere where you are, and then the shell will appear again in front of the target. The flight process of the shell in space, just like passing through space, will eventually hit the target."

Tony slowed down this time and said to Lake.

This time Lake understood a little.

"You mean, after the shell is fired, it will disappear in the atmosphere and then appear in front of the target?" Reek asked in surprise. If this happens, the Great Wall rail cannon will be stronger than he expected, and it will be difficult for the enemy to avoid it in the range.

Tony took out a piece of white paper and demonstrated it to Rick.

Tony drew a straight line on the white paper and two dots on the straight line.

After that, the white paper is folded and the two dots overlap.

Tony directly used a pen to penetrate these two points.

"Yes, just like this, the space can be twisted and folded. You don't need to understand the principle, just imagine the target you are attacking as another point on this white paper. Your shell is equivalent to the tip of the pen. The shell will break away from the dimensional space where the white paper is located and disappear on the white paper. In front of the target, the tip of the pen will appear and hit it." Tony told Lake.

After reading it, Rick felt that he had an epiphany.

"My Great Wall Rail Cannon shell can reach rapid speed in the atmosphere after being fired. After the shell reaches rapid speed, it can jump in space, indestructible and powerful. You can hit whoever you want! Just let the shell fly for a while and hit the target, no matter how far the target is." Rick said.

After hearing this, Tony thought about it and nodded, "Yes, you can just think about it. Let the shells fly for a while and you can hit it."

"I want to give it a try? Can I build a small Great Wall for me?" Rick asked Tony.

"I'm afraid it won't be tested. If you want to test, you need to build a Great Wall around the Asian region, and there are thirteen artillery shell acceleration points. This project is too huge. Even if our company's financial resources cannot support your project. The reduced version can be enough, but it is meaningless to test in the reduced model. Once the shell pipeline becomes shorter, the speed will be reduced and the speed will not reach the speed of traveling into subspace. In this way, you will see the result after launch, which will affect your idea of ​​using realistic gems to be concreted when you actually build the Great Wall rail gun in the future. Once you see the result of failure, it will limit you to use realistic gems to be concreted next time." Tony said.

Listening to it, it seemed that there was something to do. I don’t know if Tony was lazy and didn’t like to build the Great Wall for himself.

Fortunately, as long as you pass the copy and return to the main world of the earth, there is a Great Wall that has been built around the Asian region.

At that time, just install rail gun barrels and accelerators on the Great Wall.

If there are detailed drawings provided by Tony, the scientific researchers and engineering teams from the main world of the Earth should be able to complete the construction of the Great Wall rail gun.

"Okay!" Lake said to Tony. Lake was quite satisfied with the deal with Tony Iron Man.

"By the way, Thunder God Rek, since you have been to the future, will our Earth face powerful enemies in the future? Can you tell me how about if I build many Iron Man armors and arm most of the Earth's warriors to the teeth?" Tony asked Rek.
To be continued...
