Chen Fei's face suddenly darkened, his feet were faster, and he ran wildly forward.

Not long after, a small stone chamber appeared in front of him, which was similar to the entrance of the first pass just now. On the stone wall, there was also an arched pattern, and the stone patterns in the pattern also formed a complex formation.

"This is the second level." Seeing this, Chen Fei moved his heart and immediately began to observe the formation, while thinking about breaking the formation.

About a minute later, Chen Fei's eyes moved, a light flashed, and then he immediately activated the true energy breath and injected it into the stone wall along a specific pattern.

Soon, the light lit up and formed a special pattern. The formation was cracked and the stone gate rumbled open.

Without any hesitation, Chen Fei jumped and rushed directly into the passage behind the stone gate.

After a distance, some rewards such as weapons and herbs appeared. Chen Fei glanced at him and took all the things he could use with one big move, then continued to move forward and began to break the formation.

However, when Chen Fei unexpectedly came to the stone gate of the third level, the thick and mechanical sound rang again, reminding someone that he had broken the third level.

After a slight pause, Chen Fei immediately seized the time to break the formation. A few minutes later, he successfully broke the formation and entered the passage.

In this way, Chen Fei broke through the formation all the way, put away the reward items, and then rushed to the next break of the formation.

The formation of each level is more difficult than the last one. But for Chen Fei, it is not a big problem. After careful consideration, you can break the formation.

Moreover, as we broke through the barrier, although the thick and mechanical prompt sound kept ringing, it meant that someone was faster than Chen Fei.

However, Chen Fei was not panicked because he had broken the fifth level at this moment. Although he was still behind that unknown character, the time interval between the two was getting smaller and smaller.

After breaking the fifth level, Chen Fei had only less than a minute before the sound of the sound.

Moreover, the formation of the fifth level was already very complicated. Chen Fei broke it and thought for more than ten minutes. The four levels behind will only become more and more complicated, and Chen Fei will be able to catch up with the other party at that time.

Chen Fei was very confident about this. After all, his knowledge of formations was learned from the old man on Tianwu Mountain. The old man once boasted that there was no formation in this world that he could not break through by Xuanyuan Jiangshan.

Although the old man is usually a little unreliable, Chen Fei never doubts the old man's strength.

In this way, Chen Fei ran along the passage and finally arrived at the entrance of the sixth level, preparing to break through the pass and enter.

But at this moment, the thick and mechanical voice sounded, "Someone has passed the sixth level, and there are three levels left before the Dragon Tomb Treasure."

Hearing this sound, Chen Fei couldn't help but shake his whole body, his pupils tightened, and he showed a look of surprise.

Judging from the speed of the two men breaking the formation just now, although the opponent's formation level is very high, it should be lower than Chen Fei. Otherwise, Chen Fei would not have been constantly pulled closer.

But in this sixth level, the opponent's speed was unexpectedly fast, which really made Chen Fei unexpected.

However, Chen Fei did not immerse himself in shock, but quickly came back to his senses and began to study the formation of the sixth level, preparing to break the formation.

This time, when Chen Fei saw the pattern formation on the stone wall of the Sixth level, he was shocked.

Because of the formation on the stone wall, Chen Fei felt very familiar, and he seemed to have seen it before.

After thinking for a while, Chen Fei immediately thought about it. The pattern formation of the sixth level was actually very similar to the formation he cracked at the stall by Yangui Lake.

Thinking of this, Chen Fei couldn't help but feel shocked, "Does that stall owner and the four formations he asked me to break, have anything to do with the Dragon Tomb?"

Thinking of these almost instinctively in his heart, Chen Fei felt that this trip to the Dragon Tomb seemed not that simple.

However, there was not much time to think about it. Chen Fei carefully checked the formation pattern of the sixth level, and found a cracking method in less than ten seconds. After all, this formation was very similar to what he had cracked on the stall. Although some of the details were different, they were the same root and the principle was the same, so the cracking speed was very fast.

After breaking through the sixth level, Chen Fei continued to run wildly, packed up the reward items, and quickly rushed to the stone wall of the seventh level.

When I looked closely, the pattern formation on the stone wall was still very similar to one of the four formations on the stall.

Without any hesitation, Chen Fei immediately began to think about breaking the formation.

Just as Chen Fei was thinking, the prompt sound rang again and someone broke the seventh level.

"Is this mysterious passerby the stall owner or his close person?" Chen Fei thought in his heart, but the speed of breaking the formation was not much affected, so he thought quickly.

In less than a minute, Chen Fei successfully broke the formation and successfully passed the seventh level.

Then there was the eighth level, and the similar pattern again made Chen Fei almost sure that the stall owner who set up a stall on the banks of Yangui Lake was not an ordinary person.

The eighth level was broken, and the opponent was still ahead, but it was less than ten seconds before Chen Fei.

Then, we reached the last level, the ninth level.

It is still a pattern similar to the original stall formation, but there are a lot of changes this time.

Chen Fei did not waste time, so he immediately stared at the pattern formation and began to think about breaking the formation.

About five minutes later, Chen Fei's eyes lit up, his hands joined forces to move, and a wisp of true energy aura was injected into the formation, drawing into a complex and beautiful pattern, and finally flashed for a moment, and the formation broke open.

At the same time, a thick and mechanical sound sounded again, "Someone broke through all the nine passes of the dragon tomb and found the treasure of the dragon tomb."

Almost the moment the last stone door opened, Chen Fei flashed and rushed into the passage.

This time, the dark passage was not long. Chen Fei jumped for a distance and soon noticed a light ahead. He rushed out and suddenly lit up. A huge hole underneath appeared in front of Chen Fei.

The hollow is very high, and there is a cave at the highest point, from which the sun shines in.

Just below is an extremely clear pool. In the middle of the pool, there is a bluestone slab protruding from the water. On the slab, there is an old wooden box one meter long.

Seeing this, Chen Fei couldn't help but his eyes lit up, "This is the treasure of the Dragon Tomb!"

Just as Chen Fei was about to rush towards the treasure, a dark hole suddenly appeared on the mountain wall on the other side of the hollow, and then a figure rushed out in a flash.
