The meeting didn't last long, only about two hours before it was adjourned.

"Master, the little ancestor is missing." Slov stepped forward with his head held high.

Slov waited in the lounge for fifteen minutes but Cheng Yu didn't come back. He took his men to search the entire building but still couldn't find him.

To go up and down this floor, a pupil scan is required, but Slov looked through all the surveillance footage and only saw that Cheng Yu went into the bathroom and never came out.

"The little ancestor went into the bathroom and never came out. I checked and there was no passageway to the bathroom, and no one else had gone in."

Bai Yan observed the entire bathroom and found nothing unusual.

The black ribbon at the corner of the wall caught Bai Yan's attention. It was tied by Bai Yan himself for Cheng Yu in the morning.

He took the energy gun from Slov's waist and turned the energy to maximum.

Fired a shot at the wall.

Bang!

The walls of the entire building are made of special materials, so ordinary energy guns shouldn't be able to leave even a trace.

However, the entire wall shattered into pieces like glass, and a hole half a person's height was exposed to everyone.

He guessed right. If Cheng Yu had untied the ribbon herself, it would not have fallen to the ground unless the wind blew it to the ground.

Bai Yan's eyes darkened as he scanned the dark passage inside the cave. He pursed his lips slightly, obviously completely enraged.

Slov immediately understood his master's intention and hurried forward. "I've asked someone to retrieve the internal structure diagram of the entire building to detect the location of this secret passage."

Bai Yan walked towards the cave entrance without saying a word, his black eyes as sharp as a falcon's. "No need, I'll go myself."

He wanted to see who it was that could come and go freely in the central building.

He took out a small flashlight from his storage ring, calmly looked at the situation inside the cave, and stepped into the secret passage without hesitation.

Slov knew that it was useless to stop him, so he could only follow closely.

The passage was dimly lit and the air smelled faintly of dust. The remaining grooves on the wall seemed to be traces of some equipment installed, indicating that this was obviously not a randomly dug escape passage.

"This should have been dug recently." Slov touched the inner wall of the passage. A thin layer of dust fell where his fingers passed. It was obviously dug out in a hurry recently.

Upon hearing this, Slov's heart trembled. He immediately nodded to Bai Yan and tightened his grip on his weapon. The two of them continued along the passage, maintaining a high level of vigilance at all times.

The air ahead gradually became damp and cold, mixed with a faint metallic smell.

When we reached the end of the passage, a secret door appeared in front of us. The door was covered with complex patterns, and it seemed to be a special device used to block scanning.

Bai Yan knocked lightly on the door twice, then stepped back and squinted his eyes to observe the reaction of the door lock.

Sure enough, the door lock emitted a faint green light and then automatically opened a gap.

The two looked at each other in silence. Bai Yan smiled coldly, "It seems that this door is not designed to protect us at all."

He pushed the door open and saw a spacious underground room. The corners were filled with various monitoring equipment and data terminals, and there was a faint smell of medicine in the air.

But the room was empty.

"Follow this road and check for me."

It is impossible for such a big person to disappear quietly, and there are no signs of fighting, let alone struggle.

Orange Yu is resistant to ordinary anesthetics and they are completely ineffective.

Either someone knew this in advance, or Cheng Yu was sober and followed them.

He walked slowly to the instrument and fiddled with it a few times. The screen suddenly lit up, showing a series of weak pulse frequencies.

Bai Yan locked onto the rapidly jumping signal on the screen, and Slov immediately understood and quickly retrieved the detailed data of the pulse signal.

"Human body data collection?" Bai Yan's tone was as cold as ice, with a storm of rage suppressed between his brows.

Ace mentioned before that Cheng Yu's glandular fluid has special therapeutic effects, but Cheng Yu already has a contracted beast, so the glandular fluid cannot be extracted. I don't know what the other party's purpose is.

"Master, the other party should not act blindly. They need to know in advance that you will come to the central building, but..." Bai Yan knew what he meant.

Either there is a traitor in the Bai family, or someone in the alliance leaked the information.

"Keep your eyes on this road and don't miss any trace," Bai Yan ordered in a low voice, his eyes as deep as the bottom of a pool.

"If they dare to touch Cheng Yu, they must have made plans."

"Yes!" Slov immediately accepted the order and arranged for additional personnel.

A villa one hundred kilometers away.

"Long time no see, little one."

The gentle voice was like a spring breeze, and the air was filled with a faint medicinal fragrance.

The surrounding environment gradually became clear in his sight. It was an elegantly decorated villa with several exquisite oil paintings hanging on the walls.

The floor is covered with soft carpets, and the whole space exudes a warm and peaceful atmosphere.

Cheng Yu tried hard to open her eyes and saw a tall and elegant man.

There was tenderness and concern in his eyes, which made him feel indescribably at ease.

"Who are you..." Cheng Yu's voice was a little soft, like a faint echo forgotten in the darkness.

nice.

The man did not answer his question, but sat down next to him.

"Is Bai Yan good to you?" He gently brushed aside the silver hair in front of his forehead, and his fingertips ran through the hair, as gently as playing a piano.

He patiently combed the somewhat messy silver hair, his movements slow and meticulous, as if he was treating a precious work of art.

"It should be good, he took good care of you, unlike before..."

His voice became smaller and smaller, and Cheng Yu did not hear what he said next.

Cheng Yu was slightly startled, a vague memory flashed through his mind, and he felt that the man's face was somewhat familiar.

"Remember my words. Don't let your tears fall into the hands of others. Give this letter to Bai Yan."

The man spoke a little quickly, as if he was in a hurry.

His eyes were filled with concern, the kind of concern an elder has for a younger person.

In his chaotic thoughts, Cheng Yu lost consciousness again.

*

"Cheng Yu, Cheng Yu, wake up."

Bai Yan's anxious voice sounded in his ears, like a flash of lightning, piercing Cheng Yu's consciousness.

"Yanyan..." Cheng Yu murmured, his consciousness gradually becoming clear.

This is the pier of the lake island.

"Are you feeling unwell?"

Cheng Yu felt the familiar warmth from him and shook her head slightly.

Bai Yan breathed a sigh of relief, held Cheng Yu's hand tightly, and his eyes revealed an unconcealable concern.

Cheng Yu slowly sat up, his mind still a little confused, and tried hard to recall what had just happened.

"letter......"

Cheng Yu took out a note from his pocket and handed it to Bai Yan.

What era is it?

Interstellar has long entered the paperless era, and paper has almost become a rare commodity.

Bai Yan opened the letter, read ten lines at a glance, and his brows furrowed more and more.
