Lao Wen's disciples are no longer in the mood to chat with Yu Ziqing these days.

Because Lao Wen's temper became increasingly irritable, he couldn't answer a question, couldn't keep up with the rhythm at all, and just scolded him. He even kicked a student to another department to study fertilizer treated in waste gas barrels.

Lao Wen is basically the kindest head of the house on weekdays. This situation occurs simply because his patience, which is considered particularly strong among the heads of the house, has been worn away.

Of course, this patience specifically refers to patience with students.

When Lao Wen studies something by himself, no matter how difficult it is or how little progress he makes, he can still remain calm and clear-headed.

But there are so many studies and so many complicated things that it is impossible for one person to handle them all.

Seeing that Lao Wen was getting more and more irritable, Yu Ziqing didn't ask about the progress. When they met and could say a few words, Yu Ziqing just said a few words of relief, took out some food to replenish his body, and let him rest.

Take a break.

The more this happened, the more Lao Wen couldn't rest.

Yu Ziqing was right. For such a head of the school, it doesn't matter if he gets the sponsorship. Anyway, everyone is used to it. Most of the time, cutting-edge research is just to lay the foundation for future success.

But the key information was not dug out by them, but given by sponsors, so something was wrong.

If they can't come up with something further, what if they let the parallel imports of the second knife sponsor it and push it one step further.

Do you still want this face? Ah?

When he thought about how he personally took charge and made no progress for so long, but allowed a group of people who were at most similar to his disciples to make progress suddenly, he wondered if it was because his disciples were working behind closed doors and had too little practice, so they were punished.

Wasted.

The less anxious Yu Ziqing is, the better his attitude is, but the more anxious Yu Ziqing is, the more anxious he becomes.

As a result, Lao Wen took matters into his own hands and worked non-stop, almost killing those students.

Now, when those students were scolded, they had no choice but to do it. Regardless of their talent, they even worked harder than their teachers. They really had no excuse to excuse themselves when they were scolded.

Yu Ziqing hung out here, going around the Yin Demon Realm every day and quietly watching the Yin Demon plant its seeds.

As time passed, he also thought, this kind of thing is just like that.

The germination rate is appallingly low, otherwise it would be enough for one person to plant once, so why be so busy.

Then, he began to wonder if these demons had planted seeds and had other effects.

It’s not just about planting a seed, preparing for it to take root and sprout in the future, and to transform your inner demons.

In the dark night, Yu Ziqing took Zi Zaitian, Lou Huai, and Xie Jun with them. They covered their figures, used special amulets to block the sense of evil spirits, and squatted on the eaves to pretend to be divine beasts.

While watching, Yu Ziqing said to Xie Jun.

"It's hard to tell at the moment, and what purpose it has. Even they don't know it. I can only rely on you to sneak in and learn about it later.

I guess it must be very important, otherwise, we wouldn't have lost so many Yin Demons in the past few years, but we are still sending Yin Demons to do this.

If you go there, you must have the identity of a demon on the surface.

You must not accidentally become a seed-producing demon."

Yu Ziqing rambled on, but Xie Jun didn't think there was anything wrong in saying such things that he already knew. No matter how careful he was, he couldn't be too careful.

They squatted on the roof to imitate the mythical beasts, and in the meantime, they asked the two demons to take the evil king and sneak into the Yin demon's lair twice to collect information.

A month later, Wen Lingyou found Yu Ziqing with red eyes.

"Let your men quietly bring this thing into the Yin Demon's lair."

Wen Lingyou gave Yu Ziqing a dozen palm-sized discs. In the center of the discs, something made of the seven yin bones was inlaid. The specific function was unknown.

"This is?"

"I should have experimented once first, but as soon as I did the experiment, it would alert the snake.

Furthermore, it is possible to injure civilians who fell into the Yin Demon Realm after falling asleep.

The Yin Demon only moves in the Yin Demon Realm. He has never been seen outside and cannot be brought out alive.

Then we can only target the Demonic Realm.

Its lair is misty and chaotic, like an illusion, and it must also be a domain.

This is a one-time treasure specially used to destroy the Yin Demon Realm. Using the Seven Yin Bones as a guide, it will definitely be useful.

However, the specific power has not been tested and can only be estimated.

A dozen or so, probably enough to cause the domain that the nest was transformed into to collapse.

Catch all those evil spirits in one fell swoop."

Wen Lingyou was obviously a little anxious. In the past, he would have looked down on this simple and crude handling method.

Study the evil spirits thoroughly, extract their essence and remove their dross, and turn them into stones from other mountains, laying a foundation for the monk's practice that did not exist originally.

Furthermore, we need to study how to use the evil spirits after they are killed, and how to use them if they are not killed.

In fact, this kind of threat is not a particularly big species. Squeezing out its benefits and using them for my own use is the orthodox way.

Of course, Yu Ziqing did not say these words.

He just took over a dozen discs with some surprise.

"Senior, thank you for your hard work. The results are coming so soon. Okay, I'll let my people try it."

Wen Lingyou breathed a sigh of relief and said.

"This is just a preliminary result. Let's try it first. If we can suppress the demon, we can continue to study other things later.

This evil spirit is also a good thing. It would be a pity to completely eliminate it.

Some of the materials have been put into it now, and they are very wonderful, far better than most demonic materials.

The most ideal situation is to prevent the harm of evil spirits and prevent them from becoming extinct."

Yu Ziqing smiled sincerely and nodded repeatedly.

On the same day, he continued to squat on the roof with others to pretend to be mythical beasts.

"The Yin Demon's Nest is also a domain, so there is no problem with this.

Lao Wen knows that someone like me can sneak into the Yin Demon's lair, so it's not a problem.

The problem is, judging from Lao Wen's appearance, he is probably underestimating the power of this magic weapon.

If more than a dozen of them were used together, they wouldn't be able to collapse the Yin Demon's lair, and he would probably be embarrassed to leave it to me.

Therefore, we need to take our time with this action.

It is best to kill most of the Yin Demons, especially the target Yin Demon. It is best to kill all the Yin Demons.

It would be best to kill the big demon that produces seeds.

It doesn't matter to those evil demons who have no ability to reproduce and travel with little cars.

I have heard that it is a good material, so there must be a way to extract it.

This time I want to create opportunities for Lao Xie, not really to destroy the evil demon in this nest.

Do you remember everything clearly?

If it doesn't work, I will leave my body and go there myself."

"No, not so..." Lou Huai and Zizaitian rarely agreed on the same point of view, and they stopped Yu Ziqing together.

If Yu Ziqing really let the Yin God out of his body, except for that big demon, the remaining Yin demons would not be enough for Yu Ziqing's Yin God to kill.

But if you risk going to such a ghost place for the sake of evil spirits, if you get lost, you will really lose your blood.

It would be better for the two demons to go. They are really lost. They won't die for a while. With Yu Ziqing here as a beacon, maybe they can come back.

If they really can't come back, with Yu Ziqing's temperament, it's impossible to really ignore them. There will always be a way to save them in the future.

But if Yu Ziqing gets lost, they may not be able to save him.

Evil Lord also hurriedly stopped Yu Ziqing. The big strategic goal was to infiltrate from the inside and finally seize the road.

The goal of this operation is just to do something to make room for Lao Xie to sneak in.

It doesn't matter how many demons you kill.

The three of them persuaded him together, but Yu Ziqing could only listen to others' advice and gave up the idea of ​​having the Yin Shen leave the body and go there himself.

He really wanted to see it for himself.

On the one hand, understand that kind of domain, on the other hand, see if there is any inspiration.

Forget it, the mission goal is the most important.

Zi Zaitian and Lou Huai, along with Evil Lord and a dozen round magic weapons, followed a Yin Demon and quietly sneaked into the Yin Demon's lair.

Even though it was not their first time here, the two demons were still a little uncomfortable looking at the confusing and changing illusion here, with no sky and no ground, chaotic directions, and strangely colored lairs.

If it weren't for the talisman, it would be impossible for them to move here and they would get lost in the lair.

According to Yu Ziqing's instructions, they first went to the area where the Evil Lord's target, the Yin Demon, was located, and planted four magic weapons in one go. Then they quietly sneaked into the vicinity of the big demon, and used seven magic weapons to surround the city in a half circle and wrap it up.
