This time, Yang Yu didn't ask "how do you know" again.

Because Li Yu has already shown many specificities, she, as a person next to the pillow, has gradually become one with his interests, and she also knows these peculiarities.

She just asked, "What can we do with that?"

Li Yu said, "That brain god may be in control of all grievances, deaf spirit...... and even the key to the magic soldiers.

Mastering it is equivalent to mastering the followers of the Demon Emperor, all attachments outside of their own strength!

Now that your father is acting more and more perversely, he is in danger of going mad at any moment.

If it really reaches the point of no return, we can counter the brain and deal with the worst-case scenario."

"You mean to say that if he goes completely mad, then the brain god is the means to seal the town?"

Yang Yu showed a look of surprise on her face.

"Hmm."

Li Yu didn't deceive her, but there are still some details that are not explicitly said that it is not so much a closure as a rewriting of memories.

From time to time, Emperor Delong will lose his memory and forget himself.

This performance is similar to the beautiful head after the brainwashing of the god and demon Lunyin.

Concubine Wu Li (Wu Yan) is also stuck in this step and is in the predicament of gradual amnesia.

But Emperor Delong had a way to reverse it.

Perhaps, it is also closely related to the mastery of the brain.

……

Early the next morning, Li Yu came to the study.

After observing Ruyue as usual and confirming that the deaf spirit in her body had not moved for the time being, he began to look through all the letters, notes, secret files and other things related to the Brain Divine Awakening Yuanzi, looking for clues.

In fact, Li Yu has never seen the brain god Jue Yuanzi, but he only learned from Li Xin's notice in the past that Jue Yuanzi is a word and a minute, and the shape is one inch and one minute, and the color is white.

To put it simply, it's a thumb-sized person.

Just as the Eyes and Void Prisoners need to rely on the eyes of demons to nourish themselves, the Brain Consciousness Yuanzi also needs to settle in the human brain and store it in a suitable container.

"Huh? Tiangang Hall has also studied similar things, often tinkering with some human heads or brains and other objects?"

Suddenly, Li Yu successfully found the relevant clues.

When you think about it, this is not surprising.

After all, Tiangangtang was originally an institution closely related to Emperor Delong, and had been ordered to conduct many studies.

A lot of things are handled by them personally.

"Thanks to my previous dealings with them, I have a little knowledge of the yamen, warehouses, and distribution of places used for research outside Tiangang Hall.

Just go and see it in person."

Soon after, Li Yu left and began to trace it according to his own memory.

Just as the Demon Suppression Division has offices everywhere, Tiangangtang also has an expatriate agency similar to the Lantai Institute, which is convenient for finding medicine and alchemy, or researching some things that are inconvenient for people to know.

The location where the demon soldiers were found before is one of them.

Li Yu's actions at the moment are a bit like looking for a needle in a haystack.

But Li Yu was not in a hurry, and walked through the first, second, and third places as if he were watching flowers......

By the time he had roughly stepped on all those locations and had made sure that he knew what to expect, the time had already come to evening.

Only then did he quietly go back to rest and check the recovery of the snake demon's body.

After devouring the vitality of life with the Fuping Divine Pen, this great demon's body has withered a lot.

"Why does this thing look a little wilted?

It stands to reason that demons are immortal, and if you can't suck it clean, you can always recover, right?"

The snake demon's body trembled slightly, as if it was writhing restlessly.

But Li Yu did not have the slightest pity, and slipped it out again, spread out the pen and paper, and asked his own questions.

"Where is the current hiding place of the Brain Sense......

With the flow of treacherous power, the ink-black handwriting appeared on the white paper.

"West

The city is far away, next to the Yunjing Temple, ......"

Because he had just stepped on it during the day, Li Yu immediately knew what it was.

Huaiyuan Fang, outside the Great Cloud Temple, one of the workshops is disguised as a dwelling, in fact, there is a cave where the Tiangangtang workshop is located!

At first glance, it seems that it is the place where some strange machines are produced and strange weapons are made, but I didn't expect that there is something hidden inside.

It really has its own secrets that it wants to find!

"Li Ya, you put it away."

Li Yu quietly pointed to the snake demon who had fallen into a state of malaise again, and ordered.

Then he went out again and rushed to the Tiangangtang workshop next to the Yunjing Temple.

……

At night, the sky was dark and the house was full of shadows.

Because it was past curfew, there was darkness and silence all around, except for the occasional sound of barking dogs and babies crying in the distance, which was very clear in the night.

Li Yu walked expressionlessly in the shadows of the streets and alleys, as quiet as a ghost.

With the ability to see night as day and walk like a galloping horse, he soon came to his destination, and when he looked up a little, he could see all the guards and hidden sentry posts.

After briefly confirming the direction, he dived in quietly.

There was not even a means of trickery here, and after a while, Li Yu used the ability to shuttle through the void beyond the imagination of ordinary people, and went directly to the ground, and came to a relatively empty corridor.

It is clear that some of the experience of the construction of the mausoleum is borrowed here, and the overall design is conducive to defense.

In the entire underground space, there is only one path that can be allowed to enter and exit, and the security along the way is so heavily guarded that almost no one can enter and exit it silently.

Li Yu looked at the artificially built underground palace again, it seems that there are some hard rock formations, if it is not eroded and excavated with treacherous power, I am afraid that it is impossible to build it by manpower.

After realizing this, Li Yu also understood why they had to set up the experimental site here.

The selection of these bases is not untargeted, and all of them take into account the convenience of the terrain.

However, these protective measures can only be effective against ordinary Inhumans, and they are useless in the face of the Transcendent Void Realm.

Ordinary people may also be unable to catch due to their lack of control of the power of the Trick Domain, and they can't hide in the Trick Domain for a long time, just like ordinary people can't dive for a long time, and they always have to come out for breath.

However, Li Yu's mastery of the Trick Domain is far more sophisticated than in the past, and he can be called completely at ease.

Moreover, he fully understood that even if Tiangangtang had enough manpower, it would be impossible to spend all the time and energy of the master here.

Being able to send two or three Inhuman masters to alternate and patrol from time to time is already tight enough.

Sure enough, after lurking for about two moments, those stationed in the garrison patrolled the gap, and the defense finally showed a flaw.

Li Yu immediately appeared out of thin air, passed quickly without alarming anyone, and hid in the tunnel on the next floor.

Somewhat surprisingly, there were no more guards
