As soon as Huang Lao's words fell, Lin Tiancheng and the man in black walked towards the entrance of the cave at the same time, both of them were unhurried and did not feel nervous at all.

After coming to the entrance of the cave, the man in black stopped first and said to Lin Tiancheng on the side, "Are you advanced or am I first?"

Lin Tiancheng glanced at the other party with interest, and then spread out his hands, looking harmless: "I don't care!

After hearing this, a trace of cruel gaze flashed in the man's eyes, and after taking a deep look at Lin Tiancheng, he didn't speak again, raised his feet and walked towards the cave, and disappeared from everyone's sight in an instant.

Lin Tiancheng didn't follow up in a hurry, but stopped at the entrance of the cave for five minutes before stepping into the cave.

After entering the hole, there is a curved tunnel inside, stretching downward, under the illumination of the flashlight, it can be clearly seen that this corridor has been some years, from time to time there are water droplets dripping from the top of the cave, accompanied by the sound of ticking to the ground.

Lin Tiancheng didn't walk fast, he walked slowly in a walking attitude, and his mental head was also highly concentrated.

There are two things here that Lin Tiancheng needs to pay attention to, one is in this unknown place, and no one knows if there will be any danger.

In addition, you must always be wary of the man in black who came in before, and the plan when I came was to prepare to kill that guy at the first opportunity, but I can't keep it that way, and people think the same way, in case I don't do it before I get it by the other party, it's not a strong x not a counter-**!

Lin Tiancheng walked while thinking, and unconsciously walked for almost half an hour, but still didn't see the end of this road, Lin Tiancheng couldn't help frowning, and estimated in his heart that his position should be dozens of meters deep from the mouth of the cave.

After looking around again, I found that there was nothing special, and the only difference may be that the width of the corridor has become narrower than when I came.

"If you come, you will be safe!" Lin Tiancheng muttered in his heart, he could only move on!

More than half an hour passed, and just when the road had become so open to only one person that Lin Tiancheng finally saw the end.

Standing at the end, Lin Tiancheng was greeted by a spacious hall in front of him, and there was a flash of fire around this hall, which set off a hint of mystery in this hall.

After observing the surroundings, he didn't find anything abnormal, and he didn't see the man in black who came in before, Lin Tiancheng didn't hesitate and entered the hall directly.

After a closer look, he found that this hall was very empty, there was nothing, and the only thing that attracted Lin Tiancheng's attention was that there seemed to be some murals carved on the walls on both sides.

And the content of the mural is very strange, it seems that people of two races are fighting each other.

One side looks very similar to a human being, while the other side looks very strange, obviously not a human being, and what makes Lin Tiancheng most curious is that on the human side, there is a sword flying in the sky, constantly harvesting the heads of people on the other side.

Just looking at the content in the mural, Lin Tiancheng could imagine how bloody the scene was at that time, and it is estimated that it would not be able to pass the review if it was made into a TV series...

As he looked at the pictures one by one, Lin Tiancheng seemed to have understood something.

This story should be about the war between two races, and the time should last for a long time, and it can be seen from the content on the mural that neither of these two races seems to be ordinary people, and from the scenes on the mural, they seem to be similar to the current cultivators.

Because in it, Lin Tiancheng saw a lot of cultivators' methods, and even saw the picture of spells and spiritual weapons flying.

And the focus is on the next few paintings, the main content of which is that the flying sword before seems to have been hit hard by some force, and it has split into nine swords.

Seeing this, Lin Tiancheng had a throbbing feeling in his heart, as if the content of this painting had something to do with himself, but he couldn't grasp that trace of inspiration, which made Lin Tiancheng very confused, and he stood in front of the mural and thought for a long time and didn't come up with one, two, three.

Since I couldn't figure it out, I stopped thinking about it, so I looked at the last picture.

The content of this picture is also rich in connotation, according to Lin Tiancheng's understanding, it should be the war between the two sides to the end, it seems that the human race has won a tragic victory, and the other party does not seem to be slaughtered, but as if the entire race has been sealed.

This made Lin Tiancheng very puzzled, the battle between the races, to say that the tragic point is the battle of extermination, since it is victorious, why do you want to seal it? Isn't this a super nuclear bomb that will explode for future generations that does not know when it will explode!

According to Lin Tiancheng's idea, that is, to eliminate the evil and leave no future troubles.

"I don't understand, I don't understand. But why haven't I heard of this myth before, I'm studying history anyway, could it be that I happened to skip class when I took this paragraph?"

Lin Tiancheng laughed at himself helplessly.

After looking at the murals, Lin Tiancheng looked at the innermost part of the hall and found that there were five holes there.

After observing in front of each cave, I didn't find anything different, they were all the same, and there were black holes inside, and I couldn't see anything clearly, obviously it was the kind of tunnel when I came.

But there were four openings here, and they must lead to four places, and he was confused as to which way to go.

He definitely didn't know where these four roads led, but it definitely didn't lead to one place or maybe the experience was different, otherwise, who would have made four roads so painfully.

"Which way did the man in black got?" Lin Tiancheng had to wander back and forth in front of the four cave entrances to observe, muttering in his mouth.

Lin Tiancheng wanted to confirm which one the other party was taking, he was good to follow behind, a praying mantis to catch cicadas, and the yellow finch was behind, if there was a special situation inside, and he would be even happier if he was pitted at a critical moment.

But now there is no way, faced with multiple choice questions, Lin Tiancheng has no choice but to use his usual formula:

"Three long and one short selection is the shortest, three short and one long selection is the longest, the length is different and the selection is b, the uneven selection is D, the same long selection A, the same short selection C, mainly copying, supplemented by Mongolia, combined with Mongolian copying, must pass!"

This is the mantra he used to make when facing exams in school, and he will use this method whenever he is faced with a choice, and he will turn evil into good luck every time.

After Lin Tiancheng observed these four holes again, he found that there was a slight difference between these four holes, that is, the size of the holes was somewhat different.

So Lin Tiancheng used the principle of choosing D if it was uneven, and decisively walked towards the last hole...
