Douluo Dalu: Yin and Yang Judgment

Yechen and Xu Tianchen talked for about half an hour, but no one knew exactly what they talked about.

During this period, Yechen also stuffed a tiny object into the opponent's hand, and after the conversation, he joined Liu Yaxuan, and the three of them came to the cafeteria together and simply ordered some things.

"Brother Tianchen, you must keep in mind what we talked about today. In the event of an accident in the future, that thing can save your life." Ye Chen reminded with a solemn expression, the matter is of great importance, and he must ensure that his plan is foolproof.

If Xu Tianchen died, no matter how many things he did, it would be useless.

Xu Tianchen's expression was equally heavy, and he nodded to show that he understood that the plan Yechen just said, even he, the prince of the Sun and Moon Empire who was used to schemes, had to admit that it was strict and cautious.

Even Yechen has already made a detailed plan for the road ahead, and even if there is a mistake in a certain link, there are other ways to deal with it.

What Xu Tianchen has to do now is to follow this plan.

In fact, Yechen didn't want to reveal everything, so when he told the plan, he held back a little bit.

After all, this matter is no different from treason. The fewer people who know about it, the better. Even though Xu Tianchen has initially passed his test, human nature is really hard to say.

Xu Tianchen has a huge weakness, emotion.

As long as he finds a way to catch Liu Yaxuan, no matter how determined his will is, Bao Buqi will still reveal his plan.

On the way back to the laboratory.

Yechen unleashed his spiritual power and kept observing every move of the people around him.

Half a month ago, he had seen the mysterious black-haired boy here, so he wanted to see if he could meet him again.

But the result disappointed Yechen, not to mention the other person, even the extremely evil aura back then did not reveal the slightest bit.

Yechen knew that the other party might have used that almost weird disguise ability, but a person's aura cannot be easily changed.

The evil aura on the young man's body is so strong, Ye Chen can't believe that there is no trace of it that can be disguised, even if ordinary people can't find it, he has a corresponding attribute in his body, it's impossible not to notice it at all.

From this point of view, the other party did not appear here.

Yechen shook his head. There is no rush for this matter right now, so he can only pay more attention in the future.

Looking at the two people holding hands and showing sweetness in front of him, he not only thought of the person who was thousands of miles away: "I don't know what happened to Dong'er."

It's been nearly twenty days since he left Shrek, so many things have happened in this short period of time, Yechen has too many things he wants to tell the other party, but he has a heavy responsibility on his shoulders, so he can't help him to make a choice.

...

Unknowingly, the sun skipped due south, and the light deviated from due west.

In the first room on the left hand side of the laboratory, Yin Fan was sitting in front of the experimental table, playing with a piece of dark blue rare metal in his hand.

"Deep Sea Emperor Crystal?" At this moment, a suspicious voice sounded in the room.

On the other side, the door was not closed, and Yechen's young figure appeared in sight.

"You come in first.

"Yinfan was not surprised that the other party returned to the academy. After all, there were records of entering and leaving the laboratory. After checking it for a while, he knew that Yechen had returned to the laboratory in the morning.

Yechen stepped forward, smiled without any scruples and said, "I'm back, old drunkard."

For some reason, he suddenly wanted to call him that.

Yinfan smiled instead of anger, besides the soul guide, the most inseparable thing in his life is alcohol, so it's okay to call him an "old alcoholic".

Others are drunk, but he is just the opposite. Sometimes a subject can't be solved, and often a pot of the most common wine can make him find inspiration.

"Don't talk about this first, tell me, how did you recognize that this is the Deep Sea Emperor Crystal?" Yin Fan stared at Ye Chen with burning eyes, and his eyebrows were furrowed together, fully revealing his inner doubts.

The reason why he was surprised was because the deep sea emperor crystal was used as the core formation material of the ninth-level soul tool, and even the soul engineers below the eighth level in the Sun Moon Empire didn't know much about it.

But Yechen, a boy from Shrek Academy, called out his name the first time he saw it.

Yechen had a flash of inspiration, and a sly look appeared on his face: "Of course I know that in Shrek Academy, there are many such materials, and they are piled up in the warehouse. Not only this material, but also other materials. It's just that we lack the most important technology to make it into shape."

Having said that, Yechen focused his attention on the Deep Sea Emperor Crystal in Yinfan's hand: "And I also know that the darker the color of the Deep Sea Emperor Crystal, the better the quality. The piece in your hand is only of a medium level."

Immediately afterwards, Yechen described the characteristics and functions of the deep sea emperor crystal, and even explained the origin clearly.

Following these explanations, Yin Fan became more and more startled. At first he simply thought that Ye Chen was bragging, but when he saw that Ye Chen knew so much about the Deep Sea Emperor Crystal, he couldn't help becoming suspicious again.

"I don't know how to make a draft if I'm talking big. Do you know how precious the deep sea emperor crystal is? It's piled up like a mountain. I believe you are the only one!" In the end, Yinfan still chose to believe his own common sense, thinking that the situation Yechen said was wrong. may appear.

It is true that Shrek Academy has a profound background, and he also believes that it can collect a large amount of rare metals, but you must know that the only remaining deep sea emperor crystals in the mainland are almost all in the hands of the Sun Moon Empire, and even if some are occasionally spread, the number is extremely limited.

But what Yechen said later made him hesitate again: "If you don't believe it, you can go to Shrek City to have a look. I believe that you will never be disappointed."

A strong self-confidence emerged from Ye Chen, but Yin Fan looked crazy on the surface, but he was actually very shrewd in his heart, and quickly understood what Ye Chen meant.

"Okay, I won't listen to your nonsense anymore, if you have nothing to do, hurry up and don't disturb my research on soul tools."

Yechen shook his head helplessly, there is a saying that is true, you can never wake up a person who pretends to be asleep, Yinfan is obviously playing sloppy with him.

"Hey, these days, to be honest, I don't even believe it. Forget it, Teacher Yinfan has something else to do. Although we came back, we didn't bring back any research results this time. Look..." After thinking about it, he still Going to ask.

Yinfan had already guessed his intention, waved his hand, and said impatiently: "You don't have to worry about these things, I have already arranged them, so that old bastard won't find out."

The corner of Yechen's mouth twitched a few times, this old drunk really didn't know any scruples, there was no doubt that the old bastard he was talking about was definitely Jing Hongchen.
