After Jiang Chen entered the cave, it was pitch black at first, and he couldn't see his five fingers when he stretched out his hand, and he couldn't see anything.

He didn't know that there was a second seal outside, and from time to time he turned around to be vigilant to the rear.

As he went deeper and deeper, light began to appear in front of him.

There is no such thing as a cave.

After walking nearly 100 meters, the brightness was no different from the outside world, like daylight.

There was a line of inscriptions on the stone wall, Jiang Chen approached and looked at it very cautiously.

When he finished reading it, he let his guard down.

The inscription was left by Lin Luohan when he left, and the two seals on the outside were set by him in order to prevent prehistoric humans from entering here.

In addition to the inscriptions on the stone wall here, there are also more than ten meters ahead.

Jiang Chen stepped forward to check, and the inscription was as follows:

Two hundred meters in front of the stone wall on the left, there is the thaumaturgy of the Qimen Dunjia left by the sages, and those who are destined can study it.

"Qimen Dunjia?"

Jiang Chen's face changed slightly.

In fact, he had always been curious about why Lin Shuai was able to set up a seal in the A-36 mountainous area, after all, there were few people in the world who knew about seals, and he had never heard of any sealers or anything like that.

Now he understands!

Jiang Chen ran forward quickly, and there were two roads at the end, one turned left and the other turned right.

On the left turn is the word 'sheng'.

On the right corner is the word 'death'.

The font is ancient characters, apparently not left by Lin Luohan.

There is also a line of inscription below the word 'death' at the right turn, which was left by Lin Luohan, and the inscription reads as follows:

There is an unnamed exercise on the stone wall of 50 meters to the right, and the exercise is a fragment, if you can't find the rest of the continuation within the specified time, you will die violently.

Study with caution!

The last five words are much larger than the previous inscriptions.

Jiang Chen turned left and looked at Qimen Dunjia on the stone wall.

Maybe it's because he can sense aura, when he looks at these fonts, these words seem to be alive, and his mind is automatically demonstrating the mystery of Qimen Dunjia.

All kinds of formations and seals were deeply rooted in Jiang Chen's mind.

Jiang Chen felt that it was only ten minutes of effort, and he was out of this state.

But when I looked at the time on the military watch, 24 hours had passed!

A rush of hunger followed.

Jiang Chen glanced around, there were some wild vegetables and mushrooms, there was no shortage of water, and there was a dripping spring.

After checking, the mushroom is not poisonous.

So he picked up some grass and trees, Jiang Chen drilled wood to make fire, roasted mushrooms and ate them.

When he was roasting the mushrooms, he saw that there were still some characters under the Qimen Dunjia characters, which were also ancient characters, not carved by Lin Luohan.

The text reads as follows:

Seeing is fate.

If the font breaks, it can be inherited.

If the font is in good condition, only one person can study it.

Heavenly reincarnation, don't deceive yourself.

Seeing this, the doubts in Jiang Chen's heart were solved, it turned out that it was not because Lin Shuai did not leave a legacy, but because of the words here.

From this point of view, Lin Shuai is a trustworthy person and worthy of admiration.

Jiang Chen gulped down the mushrooms, although they were not salty or light, but they were hungry.

"Go and look to the right."

Jiang Chen got up, and at the moment when he got up, a sudden change occurred.

"Click......"

Cracks appeared in the text of Qimen Dunjia on the mountain wall, and they all fell off to the ground and turned into powder.

On the mountain wall, there are only seven big characters left: the top of the triple can be a teacher.

In other words, when Jiang Chenqimen Dunjia reaches the level of threefold, he can teach it to others.

Jiang Chen can understand this sentence, now he has a very clear understanding of those formations and seals in his mind, but he doesn't know how to express it, if he teaches it to others now, it will only harm others.

"First of all, no matter which sage left it, your old man can let me teach this mastery, and I am also a great benefactor of all mankind, I will kowtow to you three times on behalf of all mankind."

After speaking, Jiang Chen knelt down and kowtowed three times.

Then he came to the right, which was full of stones, not even a single plant, and lifeless.

It really answered the dead word.

On the stone wall, there are some ancient characters engraved, but they are not complete.

At the bottom is Lin Luohan's inscription:

It's the twilight of my life again.

Studying this method is really helpless.

2452, August.

Jiang Chenweileng: "This is the year before the defeat of prehistoric humans?" Could it be that Lin Shuai only studied in 2452? ”

There is also a line of inscription below:

The last time I came here, if I couldn't find the rest of the exercises after studying this exercise, the deadline was one year.

In the future, those who are destined to learn it carefully.

2453, August 23.

Jiang Chen frowned.

Lin Shuai was sealed on August 24, 2453 in the mountains of A-36 and died.

No wonder Lin Shuai didn't leave this exercise, it turned out to be a remnant of only one year!

Lin Shuai did not die of serious injuries, but ...... I didn't find the rest of the exercises!

Jiang Chen returned to reality, and his face became solemn.

His situation at this time was different from Lin Shuai, Lin Shuai's prehistoric humans outside were not so strong at that time, and he could rely on the formation and sealing technique in Qimen Dunjia to leave.

But what about Jiang Chen? He didn't even have the strength of a first-level ancient martial artist, and the formations and sealing techniques he used were effective against prehistoric humans?

But......

Even a big hero like Lin Shuai couldn't find the rest of the story, how could he find it?

Taking a deep breath, Jiang Chen looked at the nameless exercises on the stone wall.

He didn't have a choice.

The only things that could be eaten in the whole cave were wild vegetables and mushrooms, and the amount of food that was enough for two days at most, after which he would go hungry.

If you want to go out, you can only learn this nameless exercise.

If you learn, you can live for another year.

If you don't study, you won't even survive for a week!

He can't die.

He must live!

If you don't find the rest of the article, it doesn't matter, and it doesn't matter if you die after a year!

But Jiang Chen had to study Qimen Dunjia to the third level and then teach it to others.

This will be crucial for the war a year later!

Having made a decision, Jiang Chen immediately took action.

Probably because of the fragments, these words are not as wonderful as Qimen Dunjia, and they automatically evolve in his mind, but rely on Jiang Chen's own understanding.

To put it bluntly, most of the fragments on the stone wall are exercises to condense aura.

The remaining few are incomplete moves, only half a move.

Jiang Chen began to condense the aura according to the requirements of the nameless exercises, and at the moment when he condensed, the surrounding aura all rushed towards his body.

In less than a few seconds, the aura in his body had accumulated to the standard of a first-level ancient martial artist.

But......

He didn't break through to the second-level ancient martial artist.

The aura is still blindly rushing into the body, and the body has a feeling that it is about to explode.

Jiang Chen was a little anxious, could it be that the way he practiced was wrong? If this aura explodes and sacrifices in the body, it will be a big joke.

At the same time, the cave is more than 20 meters away.

The faces of the nine prehistoric human elders changed in unison, and they could clearly sense that the aura around them was rioting, and it was surging towards the cave.
