I don't know how long it took, Li Yu woke up from a drowsiness. When I opened my eyes, it was pitch black all around, and there was only one direction where some light came through, and I could vaguely tell that I was still in the stone chamber where Fan Wuxian was. The assassin's instinct made Li Yu not hesitate in the slightest, he rolled over, flashed behind a cabinet, and with the short sword in his hand, listening intently to the sounds outside.

In the direction of the entrance of the cave, there was a rumbling sound, and along with these sounds, fresh air from outside kept pouring in, driving away the poisonous gas in the stone chamber, and it was because of this that Li Yu came to his senses. In the rumbling sound, Li Yu could still hear some human voices, which seemed to be talking about something:

"It's been blowing for so long, it should be almost, right?"

"I don't think the air in this cave seems to be so stuffy, it smells quite refreshing, maybe there is a hole in it."

"Okay, turn off the blower first, you wait here, I'll go and have a look first."

"Teacher Yang, how can you go in first, or me and Senior Brother Gong go in first."

"That's right, Mr. Yang, you're old, let's go in first."

"It's okay, Xu Yingying, Gong Zhenya, you two go in first to have a look, if the situation is not right, come out quickly, don't stay. Also, it is enough to bring a micro-photoshooter, not strong light. If there are artifacts in the cave, they will be damaged under strong light......"

"Hehe, senior brother, you have to protect me......"

The sound of footsteps and the voices of a man and a woman growing closer and closer, all the way into the stone chamber. A ray of light swept through the stone room, and Li Yu hurriedly hid his figure. At this time, I heard the female voice screaming, it turned out that I saw the sitting statue of Fan Wuxian on the platform, and I didn't know what medicine this old man used.

"Ahh

"Senior sister, don't make trouble, this is just a sitting body...... However, such a well-preserved body is an important archaeological discovery that must not be destroyed. The man said with excitement.

"Senior brother, why do I feel a little dizzy, is it a lack of oxygen?" The woman muttered.

"Dizziness? No, I also feel a little weak...... Sister, sister! No, Mr. Yang, Mr. Yang, the hole is poisonous! The man shouted twice, and then fell down with the woman.

There was chaos outside, and the man who was previously known as Teacher Yang was shouting, "Withdraw out, can't go in!" Find a gas mask and go in and save people! ”

Don't leave now, but when.

Li Yu immediately recognized the shape. Obviously, there was a group of people outside who had made a special trip to visit the Medicine Master's Cave, and their conversation made Li Yu feel a little unfamiliar, and he didn't know what the origin was. The two people who came first were poisoned by the "thousand-year-old drunk" remaining in the stone chamber and had fainted. The people outside did not dare to come in lightly, and they were preparing some tools to save people.

This kind of hectic time is the most suitable for Li Yu to fish in troubled waters and escape from the Medicine Master Cave. Otherwise, when the people outside calm down, calmly blow away the filth in the hole, and then come in with the lamp, Li Yu can only end up being caught in the urn. I don't know whether the other party is friend or foe, but in any case, exposure to others is a very risky thing.

Taking advantage of the fact that the people outside had not yet come in, Li Yu quickly packed up his things and picked up the wooden box that he took out of the closet. Just as he was about to close the closet, Li Yu hesitated slightly, took out a cloth bag from his backpack, indiscriminately packed the medicinal herbs and bottles and jars in the closet, and carried them on his back. He had previously thought about not touching Fan Wuji's collection, but now he had changed his mind. This old thing, what kind of thousand-year-old drunkenness trapped himself in this hole, I don't know how many hours have passed, and it is difficult for Li Yu to get out of the evil anger in his heart if he does not go along with his things.

After waiting for a while, Li Yu heard footsteps coming from outside the cave again, and through the faint light in the other party's hand, Li Yu could see that there were six or seven people coming in, each with a strange mask on their face, and they were wearing heavy armor-like clothes. When they found the two men who had come in on the ground, they picked them up and hurried out. The cave was twisted and turned, and stretchers could not be used, so they had to carry people out to rescue them.

The dim light gave Li Yu an opportunity, and he quietly leaned forward, pretending to be one of the rescuers, clinging to them, and blending into the entrance of the cave. Seeing that the two people were rescued, the people outside didn't care about anything else, and rushed up, some shouted the names of the poisoned, and some shouted to take the stretcher quickly, Li Yu rushed out with an arrow, and before the others could react, they had already burrowed into the bushes on the side.

"Hey, who ran away just now?" The sharp-eyed man looked in the direction of the bushes and asked his companion blankly.

"Is there one?" Most people don't even notice this.

"Maybe someone is in a hurry, so it's convenient to go, right?" Someone speculated.

"Phew, these boys are really not particular, they look quite regular at school, and they ...... when they get to the wild."

"What are you thinking, why don't you go and see how you welcome them!"

“……”

Li Yu crouched quietly behind a bush, observing the group through the gaps in the branches and leaves. He was surprised to find that the clothes of these people were very different from his own cognition, both men and women, they were all dressed shortly, especially those young girls, wearing short shirts and shorts, revealing their white arms and calves, which made Li Yu look frightened. The hairstyles of these people are also very novel, and the men all have short hair, some of them are less than half an inch short from the scalp. Although the women have long hair, no one has a bun, but it is tied at the back of the head, fluttering, but it looks quite rich.

Looking at the equipment of these people, it is even more beyond Li Yu's imagination. There were several wheeled devices at the scene, like extremely luxurious carriages, but the animals pulling the carts were not visible. The sound of the machine that Li Yu heard earlier had resounded, and Li Yu followed the sound to see that it was just a game the size of a rice bucket, and something in the middle was spinning at high speed, spewing a strong air flow into the hole. Many people are holding a small object less than the size of a palm, faintly emitting some fluorescent light, I don't know what magic weapon is.

"No, this is a place of right and wrong, and I must leave immediately."

Li Yu said to himself secretly. He couldn't figure out where these people came from, and he was even more terrified of their ability to manipulate machinery. The duty of a killer is to judge the situation and never fight against opponents who can't see through the details. Since the skills of these people are incomprehensible to Li Yu, then his best way to deal with them is to avoid their edge and run away first.

Thinking of this, Li Yu slowly stepped back without making a sound. He retreated until he couldn't see the other at all, then he turned around and ran wildly out of the valley.

After running for four or five miles, I have come to the mouth of the Yakushi Valley. Li Yu stopped, took advantage of the cover of the woods, and examined the surrounding environment, and couldn't help frowning.

This road was once walked by Li Yu, according to Li Yu's memory, but it was the first day. However, when Li Yu opened his eyes to look for the markers he was familiar with, he found that everything had changed.

On the cliffs on both sides, I don't know when many pine trees grow. On the top of the cliff, Li Yu also saw a tall pillar with several strange things on the top, and four words were written on the pillar: China Mobile. He remembered that before entering the valley, he had made a mark on a neem tree with a thick cup, but when he found this sign, he found that the neem tree had grown to the thickness of the mouth of a bowl, and if it wasn't for the mark carved by himself, he almost suspected that he had found the wrong target.

"This ...... Could it be that one day in the cave, a thousand years have passed in the world! ”

Li Yu stroked the already vague marks on the trunk of the tree, and his heart seemed to sink to the bottom of the sea.
