After swearing sovereignty, Yu Zehai looked at the Grand Canyon in front of him with a smile.

The canyon is full of trees, grass and flowers, as well as flocks of sika deer, fluttering butterflies and hard-working bees...... The whole canyon gives a lively scene. In the air, there is not only the aura of heaven and earth that makes Yu Zehai intoxicated, but also filled with bursts of fragrance, the fragrance of a hundred flowers, and at the same time, it is also mixed with a strong medicinal fragrance.

What a treasure!

Yu Zehai looked left and right while wandering around the Grand Canyon.

In the deepest part of the canyon, on the cliff wall on the bank of the pool, there is a square cave. The location of the cave is about five meters from the ground, and the careful Yu Zehai found that there is a row of potholes on the cliff wall from the bottom of the valley to the entrance of the cave.

Above?

Still not on?

Yu Zehai stood under the cliff and looked back, climbing the five-meter cliff was easy for him at the fourth level of qi refining, not to mention, there were potholes dug by predecessors on the cliff, so it was undoubtedly easier to travel up and down.

Moreover, after this circle is turned, in addition to the pool next to him, there is only this cave in front of him. There is no doubt that if you want to solve the mysteries of this canyon, there will be something in the cave!

"Matou, help Baba see if there is any danger in this cave?" Yu Zehai patted Matou's head and pointed to the cave in front of him and said.

The heart of defense is indispensable.

No!

It should be said that it is indispensable to prevent beasts!

The cave is about five meters above the ground, and although the invasion of most wild beasts has been eliminated, it cannot be ruled out that there are such small creatures as snakes, insects, rats, bats, spiders, etc., and these small creatures will never be stumped by a mere five-meter cliff.

And.

The most important thing is that if this cave is really the retreat of any of its predecessors, no one can guarantee that there are no traps or other security measures in the cave?

"Xiu~Xiuxiu......"

Yu Zehai could only roll his eyes helplessly at the pomp head's shout, he didn't understand!

However, fortunately, judging from Ma Tou's reaction, it was quite normal, and he did not show any uneasiness or fear. You know, animals are naturally sensitive to mysterious and unknown dangers, which is a racial talent, just like some human beings' sixth sense that comes and goes, and 'seeking good fortune and avoiding evil' is their ability to survive under the law of the jungle.

Especially pockmarks!

Since following Yu Zehai, the spiritual spring in the space in the tower has not been drunk, and the food rich in spiritual spring has not been eaten. In fact, not only the hemp heads, but also the little ones in the family, have become more spiritual, more intelligent and witty. Therefore, when he saw that Matou did not show any restlessness, Yu Zehai was not only relieved.

In this way, the cave is at least safe enough to explore!

"Let's go play by yourself, Baba is going to the cave to find out!" Yu Zehai grabbed a fish from the space in the tower and threw it to the other party, and then he couldn't wait to walk towards the bottom of the cave.

For rock climbing, Yu Zehai is no stranger to it.

In fact.

Not to mention rock climbing, that is, climbing trees and climbing electric poles, Yu Zehai did not do it less when he was a child, for this reason, he was beaten by his parents back then. Farm children, with short knowledge, information blockage, and never know much about electricity, do not know the harm that high and low voltage electricity can cause to human beings. Therefore, when they climbed the telephone pole, on the one hand, they felt fun, and on the other hand, they also had the intention of comparing themselves with each other and not admitting defeat.

"My baby can climb trees!"

"Cut! What is it to be able to climb trees? My baby can still climb telephone poles......"

Climbing trees and telephone poles is easy to see.

Therefore, this is not only the case for children, but also occasionally in the hometown.

The entrance of the cave is not wide, only two or three people can pass through, at first glance, the cave is slightly dim, but there is a faint light emanating, it looks quite a bit of mystery.

The cave seems to be man-made, but there is no trace of an axe. Of course, there may have been traces of knives at the past, but because the time is too old, those traces of chisels have been weathered by time, and then they have become very blurred.

"Huh, I strangled the grass! Is this the legendary pearl of the night?"

After just a few steps, Yu Zehai made a new discovery. On the cliff wall at the top of the cave, almost every few meters there is a stone the size of a dragon's eye, and the stone emits a faint light, trying to drive away the darkness in the cave.

Yu Zehai had seen a lot of crossings in his previous life, so when he saw these stones above his head, he immediately remembered the Night Pearl. In fact, Yu Zehai only later realized that these things were not night pearls, but the most primitive fluorescent stones.

Fluorescent, also known as noctilucent stone, is actually an ore containing luminescent substances, which is formed by the initial magma eruption and the subsequent geological movement, which accumulates and absorbs a large number of mineral elements. If this kind of stone containing rare luminous elements is artificially processed, it becomes what is often called the pearl of the night.

After walking more than ten meters, the scene in front of him couldn't help but surprise Yu Zehai!

What caught his eye at this moment was a spacious space similar to a cave, the entire space was about four or five meters high, and the area was more than thirty square meters.

The spacious space in front of me is called the 'Hall', with a stone table in the center of the hall and two stone benches on the side, but other than that, the hall is empty. Moreover, what made Yu Zehai wonder was that although the hall had gone through vicissitudes, it was surprisingly not a trace of dust and dirt.

Even, even the stone tables and stone benches, Yu Zehai reached out and wiped them one by one, spotless, clean as new!

"Is anyone there?"

Yu Zehai shouted in a ghostly voice, but the only thing that responded to him was infinite silence.

What the hell!

Yu Zehai muttered something in a low voice, and then began to look around the hall.

If it comes, it will be safe.

Yu Zehai is not the kind of person who likes to drill the horns of the bull, if there is any danger, he will come to the door, he just needs to improvise. He is a man in two lives, and he has received national higher education in both lives, Yu Zehai thinks that if he talks about fighting wits and courage, his wisdom will not be inferior to that of the ancient sages.

Of course.

If there's no danger, then explore with peace of mind.

Compared to the passage outside, the hall in front of it is multiplied with glowing stones, illuminating the entire hall. Despite this, Yu Zehai, who was cautious and subtle, took out a flashlight from the space inside the tower and searched carefully.

However.

To Yu Zehai's disappointment, the rock walls on all sides of the hall were as smooth as mirrors, except for the stone table and two stone benches, it could basically be said that there was nothing here, and the four walls, the top, and the bottom were all smooth cliffs, and there were no passages and secret passages...... It seems that the hall in front of you may be all that the entire cave has.

"Something is wrong!"

Yu Zehai rubbed his chin and whispered to himself.

Although it seems that the 'facts' in front of him are like this, Yu Zehai doesn't think so in his heart.

According to the habits of human thinking, it is impossible to dig such a large cave with great effort, and it is impossible to get a stone table and two stone benches to sit down and drink tea? Since it is a cave house, what about the place where the tip is settled? What about the place where the fire is lit and cooked? As long as it is a human being, it is impossible not to rest, it is impossible not to eat, and it is impossible to sit here all day and drink tea!

In this way, this stone chamber has a secret, and it is a big secret. It's just that Yu Zehai hasn't found it so far.

Yu Zehai held a flashlight in one hand, and carefully groped on the stone wall inch by inch with the other. Touched and knocked and knocked and touched, and then from this side to the next, and from the next cliff back to this side...... Repeated so many times, Yu Zehai's face was full of helplessness.

There are quirks in this stone chamber!

He'd already decided that, but what was going on?

After a few laps, even Yu Zehai, who had excellent patience, was a little unhappy at this time.

Because the stone chamber was so large, whether it was the top, the ground, or the cliffs on all sides, he had carefully searched inch by inch, but he didn't find anything.

"It shouldn't be!"

Yu Zehai paced as he rubbed his chin and thought.

The stone chamber was spotless, clean as new, and the furnishings inside were pitiful, except for the stone table and two stone benches, which could almost be said to be none, so where were the secrets and secrets of opening hidden?

"Furnishings, huh, stone tables, stone benches?"

Yu Zehai seemed to remember something, and suddenly slapped his palms suddenly, and scolded even more angrily in his mouth: "Damn! The feeling is that the owner of this cave is playing with the master and me in the dark!" Speaking of this, Yu Zehai turned his head suddenly, and his two eyes were staring at the stone table and stone bench in the center of the hall.

"It's a place that's the size of a palm, and it's still bare, if it weren't for the fact that the owner of the cave was playing with the dark, it would be really hell!"

Coming to the stone table and stone bench again, Yu Zehai made a new discovery, the stone table and two stone benches in front of him are integrated with the entire mountain. However, Yu Zehai was not discouraged, since the general direction is right, then the answer is only a matter of time.

Really!

Hard work pays off!

After a series of repeated explorations, observations and attempts, Yu Zehai finally found something strange as he wished.

It turned out that on the base of the stone table, there was a small mechanism similar to a "drawer". It's just that this small mechanism is not only very exquisitely set up, but also carved so vividly that it is almost impossible to tell that there is a small mechanism hidden there.

Therefore, when the 'drawer'-shaped mechanism was opened, Yu Zehai was excited!
