Having just seen Lei's attack, Genn paid great attention to his power this time. He tried his best to hit the center of the iron plate, and the speed of his punch also slowed down a bit. He could even predict that this time it would be.

Will not break.

"Click~"

Gen still had a smile on his face, but when his fist landed on the target, he was stunned. Even if he controlled the force, the iron plate easily split into two halves, falling to the ground with a clang, and then

After being waved by Ling to regroup again, Lei gloated beside him and laughed with his belly in his hands. It was obvious that his effect just now was worse, and he didn't know where he got the face to laugh at Gen.

"Failed, and I said you have to go all out. You don't need to use the energy of the mind wave, but at least you have to exert your maximum physical strength. But you just stopped your strength and slowed down a bit, so I thought I couldn't see it."

Ling pointed out Gen's mistake very strictly. She was waving a peach branch in her hand and pointing. She looked completely different from before. The smile on her face disappeared and her expression became very cold and serious.

"Sorry, I subconsciously held back my strength." Genn admitted without much quibble.

"It doesn't matter." Ling waved his hand, "I also think you can pass it the first time. Try more. You have to figure it out on your own. I won't give you too many pointers on this basis. Since you come in based on your strength.

Yes, you should have this talent."

"I'll try again." Lei stood up, "I was too fast just now."

"It doesn't matter, you can try it one by one."

In this way, Gen and Lei spent the whole afternoon here, until it was almost dark. The lantern masks came out one by one to hang paper lanterns for lighting in the small courtyard, and the sound of clanking iron was heard in the small courtyard.

It echoed in the courtyard for a long time, but neither Lei nor Gen could figure it out in the end, no matter how many times they tried.

Every line on the two iron plates has only an extremely small connection. Even a normal person with a little strength can break it, let alone the likes of Gen and Lei.

Compared with humans, they are not considered masters, but they can be regarded as strong opponents outside. Genn didn't know about Lei's condition, but he himself was also a person who had gone through the road of dueling, and his physical fitness was unknown how much higher than ordinary people.

For him, this training is like chopping wood on top of tofu. To make the tofu unscathed, the wood must be chopped off at once, which is almost impossible... Genn has experienced many tests.

Whether it was the secret realm of the blood clan or the zenith code left by the giant dragon, he used his wisdom to crack it one by one, but this time he could never find a way, not only him, but also Lei.

Ling looked down at the two apprentices from the eaves, her eyes becoming more and more solemn, and she shook her head from time to time, showing her dissatisfaction in her heart.

The two of them had been standing here for a long time, sweat dripping down their foreheads and tapping on the bluestone bricks under their feet, but Genn still didn't think of a solution, which made him a little frustrated.

Ling's expression didn't change much. She seemed to have known that he would be like this. The black iron plate cracked the last time and she didn't recover. Instead, she clapped her hands and jumped down from the eaves.

"That's it for today. Tomorrow is the official start, and you haven't accepted the ceremony yet, so I just want you to be mentally prepared and go back to rest." Ling waved her hand, and when the practice was over, she changed her serious tone.

Her appearance returned to her previous smiling state, which made Gen feel a little dazed.

"What? Are you still reluctant to leave?" She stood up on tiptoes and reached out to touch Gen's head twice.

"To be honest, I still feel a little unwilling, and I still want to keep trying," said Gen.

"Ah... come on, I'm already hungry. It's too boring to toss with these two pieces of scrap metal..." Lei was already giving up, "If it doesn't work out, we can go get some food and come back."

"Eat, eat, eat... Why didn't you die just now?" Genn complained in a low voice before continuing back to the courtyard.

Ling had already gone back to the house to rest, and instead of helping him restore the iron plates, Guen picked them up and restored them with his own hands, and then punched them again and again. Even if there was no progress, he still persisted. Guen used up all of them by himself.

The scattered thoughts were placed close to the iron plate and stood in front of him. The light thoughts clung to the surface of the iron plate like water attached to it. Gradually, Gen seemed to have discovered something.

The holes and lines on the black iron plates are not meaningless. They are arranged together in a certain pattern. Some lines are connecting points and will break when they are stressed, while some are just carved on the surface, like

Genn didn't know the meaning of some strangely shaped star maps before, but it seemed clear after he attached his light thoughts to them.

They had never discovered this before, because the condition Ling gave them was not to break the iron plate. In this way, they would reduce the power as much as possible. It was best not to use the power of thought waves. Unexpectedly, this was exactly wrong.

...Indeed, how is it possible to do this under normal circumstances? You must use thought waves. You just instinctively use thought waves to strengthen your power. Can you find a way to weaken the power? Cover it with light thoughts and use the power you exert.

All absorbed and offset.

Genn started to try with this idea. Even though he was very tired, he was still very excited after the breakthrough, as if he didn't know he was tired at all.

Just do it, Genn released a layer of light thought to cover the iron plate, like a thin film that needed to be completely wrapped. However, at this time, Genn discovered another problem. This iron plate was very unusual.

He couldn't wrap it up completely.

The strange lines and patterns on it have a strange phenomenon. Once Genn's light penetrates into those grooves, it will flow out along its trajectory. There is no way to completely wrap it up. Genn doesn't know what it is.

The principle may be that it is a structure made by some special refining method. The light thoughts that are guided out are completely controlled. They will flow along the direction of the lines, and finally pass through those few lines.

A fragile connection.

Even if the power is directed out, it will only delay time, and will still be cut off by the light thoughts flowing back in the end...

Now the problem changed from a technical problem to a mathematical problem. Genn had to think about how to arrange the light lines so that their forces would collide with each other and completely cancel each other out before reaching the connection point.

"Ah... why are you doing these things? I hate this kind of question the most." Genn had a headache, but he had to do what he had to do. He used a branch to pull it up on the ground and removed the strange things on the iron plate.

All the patterns were copied and drawn.

He had been playing all afternoon. Although he was very energetic, he did not want to waste energy by trying and making mistakes over and over again. He tried to figure out the answer to the problem on the drawing, but a dozen conjectures in a row were not correct. On this board

The star image is carefully designed, and it will always block a key road. If you use another way to solve the problem, it will block another road. Genn repeatedly thought about many solutions, but in the end he still

There is a small section that rubs against the connection point and ruins the whole scheme.

"What the hell is this!" Genn scratched his short hair irritably. In his rage, he suddenly remembered something.

By the way, since this iron plate will react to light thoughts, what about shadow thoughts? Will there be a different reaction or will it not work? Or it may be no different from light thoughts, as long as it has a reaction or has no effect.

Well, there are ways to solve it.

This is equivalent to adding a huge variable to the unchanging puzzle. Using the hedging of different reactions of light and shadow may be able to achieve the effect that Guern wants. Just try it. Guern stood the board up and inserted it into the sand.

He can no longer support it with light thoughts. He must control the variables within the smallest range. Any slight movement may make the result completely different.

Genn first closed his eyes and concentrated on feeling the flow of air. Then Genn placed his fists on both sides of his body. The light and shadow blended in the body and separated again, and merged into his two hands respectively. Genn tried hard to control the amount of air.

Keeping it as small as possible, even the uncontrollable shadow thoughts were stretched by him into thin threads. Of course, they were not as delicate as the silk threads of light thoughts, but they were as thin as twine.

Looking at the extremely familiar board in front of him, Genn hit the energy and punched out with both fists at the same time! The points he chose to focus on were also very precise, right at the two depressions in the center of the board, like the cores of two nebulae.

Average!

After the punch fell, the lines on the iron plate flickered for an instant. Two different energies, white and black, swam in the thin grooves, flowing according to the trajectory calculated by Gen. The speed of the lines was very fast.

Quickly, it kept flowing back and forth on the iron plate, like the wakes of comets dancing in the galaxy. The white and black comets kept colliding, and then flew away separately. In the end, those complicated lines left behind

A deep mark!

Genn was like looking at a shaking lottery ticket box. Every little movement made his heart beat faster. Success or failure depended on this. The two arcs of light and shadow flew faster and faster, and every trajectory was deeply penetrated into Genn's heart.

In his mind, he held his breath and stared at the deep mark on the iron plate, and finally——

The last two lines returned to the central concave point, like a comet that has been orbiting the star for countless years and finally returned to its original point. They collided together for the last time, completely canceling out the remaining power... The entire

The iron plate seemed to come alive, and at that moment it trembled slightly like a heart.
Chapter completed!
