The cliff cave is not deep, Zheng Chen has traveled less than twenty meters before he reaches the end, and at the end of the cliff cave are three forks, and three holes on the left, middle and right appear in front of Zheng Chen.

Faced with the choice, Zheng Chen did not toss a coin or rely on intuition, but squatted down to look at the road surface of the three holes, and after a moment of observation, Zheng Chen directly chose the right hole.

The reason is that the road surface at the right entrance of the cave is the most dusty, and more dust means that few people are moving, with Zheng Chen's current strength, the fewer people, the safer.

After making his choice, Zheng Chen resolutely walked towards the hole on the right, and Zheng Chen walked quickly and carefully along the way.

I was anxious because I wanted to finish exploring this mysterious cave as soon as possible, and I was careful that I was afraid that I would make too much noise to attract the people of the Demon Sect, and if I was found in this kind of place, I wouldn't be able to run.

In this mood, Zheng Chen walked for about three minutes, and at this time, he found that the originally narrow cave began to become wider, and the originally rough cave walls were gradually replaced by smooth bluestone slabs.

With the change of the surrounding environment, Zheng Chen's heart became more nervous, and after walking for about a minute, Zheng Chen suddenly stopped.

In front of Zheng Chen, a wide hall suddenly appeared, the area of the hall was the size of one-third of a football field, and the walls around the entire hall, including the ground and the top, were all made of bluestone.

At this moment, Zheng Chen's ears sounded the sound of the system's prompt.

"Players have discovered the Demon Sect Yaojin Branch, and the contribution of the personal version progress has been improved, temporarily ranking first in China!"

Hearing the system prompt, Zheng Chen hurriedly opened the ranking system, clicked on the version progress contribution list, and saw that his name really appeared in the first place.

Player Name: Bangfeng.

Current ranking: No. 1.

Personal version progress contribution: 3%.

So many players were tired and killed so many Demon Sect believers to advance the progress by 3%, and they didn't expect that they would directly contribute 3% just by discovering a Yaojin Branch.

It seems that the advancement method of this version cannot only rely on simply killing mobs, but more importantly, discovering and exploring!

Seeing that his efforts were rewarded, Zheng Chen felt that his efforts for more than ten hours had not been in vain, and after readjusting his mood, Zheng Chen tightened the face towel on his face, held the handle of the lone wolf with his right hand and was ready to pull the knife out of the sheath at any time, and slowly stretched out his right foot on the bluestone slab in front of him and nodded, and stepped on it after making sure that there was no problem.

In the empty hall, there were no people, and there was no movement, only the candle flames on the wall were constantly beating, but the more Zheng Chen was nervous, this is the Yaojin branch of the Demon Sect, how could there be no one, what about the two Demon Sect believers just now? And the previous female demon sect messenger?

Could it be that they are all in the other two holes**?

This hall is also a part of the Yaojin Branch, so no matter how important it is, someone should guard it, right?

Zheng Chen carefully watched the wind and grass around him, and kept walking towards the depths of the hall, and when he reached the end of the hall, he found that there was a bronze door on the bluestone wall at the end.

Because the two colors are close, I didn't notice it at the entrance of the hall just now.

The bronze door is not very large, the side length of the left and right sides is about two meters, the door is double-open, there is no pull ring or handle on the door, the gap between the two doors fits extremely perfectly, and it is estimated that not even a single hair can be inserted.

Zheng Chen stretched out his hands and gently groped for the door a few times, then tried to push it hard, and he was surprised to find that the door seemed to move.

Zheng Chen tried to increase his strength again, and with a slight friction sound, the bronze door was pushed open by Zheng Chen, and Zheng Chen didn't dare to open it too much, only opened it a little.

Seeing that the door was opened, Zheng Chen hurriedly leaned his head over and looked inside with one eye, and inside the bronze door was a dark world with no light.

This made Zheng Chen hesitate, he didn't dare to trespass if he couldn't see the situation inside, in case it was a demon boss's bedroom, wouldn't he be a sheep?

But Zheng Chen thought about it, and immediately rejected his idea, which boss would design his bedroom like this? There was no one guarding the door, and it was still dark inside, Zheng Chen observed at the door for more than two minutes, and after making sure that there was no sound inside, he used his hands again to open the bronze door a little half.

Zheng Chen still didn't rush in, but took out the fire fold, and after carefully blowing it, Zheng Chen put his left hand holding the fire fold into the bronze door.

Relying on the faint light of the fire fold, Zheng Chen finally saw some of the conditions inside the bronze door, and he saw some wooden shelves, similar to bookshelves, which were full of all kinds of medicine bottles.

It's a pill!

At this moment, Zheng Chen's whole heart was about to explode with excitement, and the shelves inside were actually full of pill bottles, whether it was an attribute pill or another pill, if it was an attribute pill that permanently increased the attribute value, then wouldn't he be going to heaven.

At this moment, even Zheng Chen's mind could not resist the temptation of attribute medicine, he dodged and got into the crack in the door, and after entering, Zheng Chen did not rush to close the door, but looked at the surrounding environment again with the help of the light of the fire fold.

If there is any accident, you can run out as soon as you get close to the gate.

As Zheng Chen kept moving the fire fold in his hand, he saw rows of wooden shelves, the shelves were full of pill bottles, Zheng Chen took a few deep breaths and hurriedly turned around to close the bronze door, and then walked to the nearest shelf to him and picked up a pill bottle and opened it.

Inside the bottle were several small red pills, and after Zheng Chen poured the pills into his hand, he found that this was not a drug that increased the attribute value, but an ordinary antidote.

"Day!"

Zheng Chen scolded in a low voice and put the pill back into the bottle, and then put the pill bottle back in its original position and set it up.

Could it be that all the medicines here are this kind of elixir? With so many pills, isn't there an elixir that permanently increases the attribute value?

Zheng Chen began to rummage carefully without believing in evil, but to Zheng Chen's disappointment, he didn't find any pills that could permanently increase his attribute value.

Zheng Chen, who had been rummaging for most of the day, decided to give up, there was no pill in the pill library of this Demon Sect Yaojin Branch Hall that permanently increased the attribute value.

In the end, Zheng Chen casually stuffed a few painkillers and planned to leave here after holding the principle that thieves do not go empty, but as soon as he walked to the bronze door, the whole person froze.

Because he heard footsteps outside the door, and there was more than one!

"It's really bloody! Why are you so greedy? Leaving early doesn't stop there! How good is that? I actually became a turtle in an urn! ”

Zheng Chen scolded himself for being greedy in his heart, and hurriedly extinguished the fire breaker, and then walked to the innermost part of the pill warehouse in the dark according to his memory.

Zheng Chen had just hid behind a medicine shelf and stood against the wall when he heard the sound of the bronze door being opened, and at the same time, he saw a black-robed Demon Sect envoy walking in with a lantern.

The Demon Sect envoy who walked in seemed to know that there was someone inside, and actually came straight in the direction where Zheng Chen was hiding.

Seeing the Demon Sect envoy getting closer and closer, Zheng Chen felt that his nervous hairs were about to stand up, and this nervousness was much more than the first time he went to the ring to fight.

What should I do?

Continue to hide?

What if I get discovered?

He shouldn't find me, right?

At this time, Zheng Chen's brain was in chaos, and he didn't know how to solve the situation in front of him.

The Demon Sect Envoy was getting closer and closer to him, and the moment the Demon Sect Envoy came to the medicine shelf where Zheng Chen was, a cold light suddenly flashed, and Zheng Chen actually made a move that he couldn't even believe at this critical moment.

He actually drew his sword and attacked the Demon Sect Emissary!

And what's even more unbelievable is that he actually succeeded!

This knife directly cut the throat of the Demon Sect Envoy, and actually achieved the effect of a fatal blow.

This is "Top of the Sky", in order to make the game world as realistic as possible, the game company uses a large number of AI algorithms here, all monsters, whether it is a boss or an ordinary beast, or even a fish swimming in the water.

With the blessing of powerful AI algorithms, each monster has become more realistic, they are no longer a bunch of data that only knows how to run programs, they have become smarter and more flexible, and at the same time more changeable and full of uncertainty.

The downside is that they have lost the necessary skill of ordinary online game monsters - the vigilance range.

Anyone who has played online games knows that wild monsters have a warning range, and as long as you enter the warning range, wild monsters will find you, but there is no such setting in "Top of the Sky", because the game company hopes that the wild monsters in "Top of the Sky" are truly flesh-and-blood intelligent creatures.

Today, in 2045, AI technology is very mature, and AI intelligence can imitate all creatures in the world to the greatest extent, including humans.

Although the Demon Sect Envoy was very powerful, he never dreamed that there was still a person hidden in the elixir vault of this Yaojin Branch, you must know that there was no trace of player activity within a hundred miles centered on the Yaojin Branch, how could there be anyone here?

In complete unsuspecting, he died, and his death was unknown.

"Players who successfully kill the Demon Cult Messenger will receive a reward chest, and the contribution of the personal version will be increased, and it is currently at the top of the list in China."

Zheng Chen didn't have time to check the reward chest he had just obtained, and seeing that the Demon Sect Envoy was about to fall, Zheng Chen hurriedly stepped forward to hold his corpse to avoid making a sound, and then slowly dragged him to the back of a medicine rack to hide it.

Looking at the corpse of the Demon Sect Messenger, Zheng Chen's eyes narrowed, and he actually squatted down and took off the clothes on the Demon Sect Messenger, and after a while, Zheng Chen actually put on the black robe and hat of the Demon Sect Messenger.

This thing is actually planning to pretend to be a demon messenger himself!
