The four of them disappeared into the depths of the cave, and Li Yunmu didn't have much hope for this scene, after all, the guide bee had already gone in to reconnoiter before that.

Even this small and nimble high-speed flying creature has never looked back, and most of the fate of these four people will not end well.

But now I can't think of any way for the time being, and I can only fight for the accident.

However, to Li Yunmu's surprise, in less than a week, all four of them came out alive, and they didn't have any problems except for their haggard looks.

"Yan Ya, right? Tell me what's going on in the depths of the cave?" Among the four people, the leader who has more right to speak, his name is Yan Ya, he is in his early twenties, a barbarian, he is quite tall, close to two meters and three meters tall, as for his strength, he can barely be regarded as passing.

At least, Yan Ya was stronger than the other three, and his ranking in the stone house in the fifteenth district was more than one hundred and twenty, with nineteen ox strength and seventy-three string strength.

If the strength of the top 150 rankings in the 15th district can only be regarded as a middle-level implementation level in this district, then the 120th place belongs to the upper middle level, but this is useless in front of Li Yunmu, whose strength has risen sharply.

It is no exaggeration to say that with Li Yunmu's current fifty bull strength, even if he doesn't use his string strength, just pure physical strength, one hand, and one leg, he can beat a hundred or dozens of people like Yan Ya.

That's right, the gap is so big, don't just look at the strength of thirty bulls, but if you take ten bulls as a section, this is already three sections apart.

There is simply no comparison.

Therefore, now Li Yunmu is not afraid of any careful thinking and tricks played by the four of them.

"The cave is very deep, very deep, we didn't encounter any creatures in it, not even a small plant, and we wanted to continue to investigate, but we saw that there seemed to be no end to it, so in order not to make you wait any longer, we returned. Yan Ya and the others looked at Li Yunmu cautiously.

I'm afraid that their detectives this time will dissatisfy this fellow disciple who was originally just a slightly stronger ordinary disciple and kill them at once.

Li Yunmu didn't say anything after hearing this, but just looked at the four of them silently for a while, until the four of them were sweating, then nodded and withdrew his gaze.

"Yes, you have done a good job, go down and rest, since I have made an agreement with you before, then I will not embarrass you, Zhang Ru, I will give them a wild horned sheep. Li Yunmu waved his hand and let them leave.

The four of them hurriedly nodded their heads and thanked them, and retired happily, in the past few months, because the four of them were forbidden to enter the forest, they all ate huge coconut meat and drank coconut water.

Now when I smell meat to eat, I immediately don't care about anything.

"Lord, do you really believe everything they say?" He Miao said with great skepticism.

"Therefore, we must give them good food and drink, let them relax to their heart's content, and only then will they have a chance to expose the truth. Li Yunmu replied.

"I see, then give them two more bottles of Goth's Bar. He Miao nodded and immediately went down to work.

After the people around him left, at this time, Li Yunmu said to himself: "Did they tell the truth just now?"

"Basically, most of them are telling the truth, but when they say that there is nothing in it, their heartbeat and breathing rate are unconsciously a little faster, and their usual behavior habits are slightly unnatural. The voice of the system appeared in Li Yunmu's mind.

"In other words, the depths of the cave inside, are not as they say, there is nothing at all?" I have to say, this is the embodiment of the system after the upgrade, which is becoming more and more powerful.

You must know that in front of Li Yunmu, although the strength of the four is average, they are not any characters.

But in any case, the four of them are also the martial artists of this world, and in a world where most of the main world is made up of people and civilians, they are the big shots.

These people have experienced a lot of scenes, and their psychological quality is strong enough compared to ordinary people, and it is not easy to test whether they are lying or not.

The heartbeat and respiratory rate mentioned by the system are a small beat faster, but in fact, this small beat is already a very subtle perception and capture.

If it is really described as a test heartbeat, with Yan Ya's psychological quality, his one-minute heartbeat is the same as usual, and there is no difference at all.

However, the system analyzed the details to a more subtle level, so it still detected a trace of abnormality from the other party's calm answer.

In addition, in the past three months, the system has already collected all the physical characteristics of the four people, so when they compare, it is so clear, even if the other party has some very few, almost unrecognizable details with unnatural expressions or movements, through this database that collects them in advance.

The truth came out.

The assistance of these details, which does not seem to have much effect, is always full of very practical things, and sometimes, it is often a detail, which is enough to change everything.

"Yes, at least at this point, they are not telling the truth. ”

"That's fine, after all, there are still two discovery breakthroughs. Li Yunmu's mood finally improved slightly.

Next, a few days passed, and in the past few days, Li Yunmu really fulfilled his promise and made some improvements in the living conditions of Yan Ya and the others.

Another three days passed, and Li Yunmu called them to the front again.

"This time, I still need you to go into the depths of the cave to reconnoitre, stay longer, and try to trace the end of the cave as much as possible. ”

When the four of them heard this, they were slightly startled at first, and then they didn't say much, and honestly entered the cave again and were responsible for exploring the way.

"How's that?" Li Yunmu asked again.

"After hearing that the host asked them to enter the depths of the cave again, the minds of two of them were much more active than usual. The system replied.

What does this mean?

Li Yunmu understood, it seems that these four guys really got some benefits from entering the depths of the cave for the first time, otherwise they wouldn't be excited all of a sudden.

Although the performance of the four people is very sophisticated, and they are completely silent on the surface, they have a system to monitor all their physical functions, plus the good life hospitality of the past few days.

Obviously, two people finally relaxed their vigilance, and there was finally a loophole in their emotions, but this loophole that ordinary people couldn't catch at all made the system grasp it tightly.

"Then let's go, let's go along and see what big secrets are buried in the depths of this cave. Li Yunmu nodded to Li Yun and Li Mei.

I have to say that since Li Yun gained the recognition and inheritance of this island, there are actually not many places in the entire island plane space that can make Li Yun, the inheritor, scruple to enter.

The only one is this underground cavern.
