The three of them found the same cave as the night before, which further confirmed Chen Cheng's conjecture, there was no trace of man-made repair in the cave, and it was completely natural.

The two naturally formed and symmetrical caves, the vine-covered caves that resemble nostrils, and the lakes in the shape of mouths, no matter how magical nature is, cannot be so seamless.

Chen Cheng couldn't figure it out, Bingyan and Li Wei were even more so, the three of them chatted for a long time, exchanging their respective opinions, and finally failed to discuss the reason, so they could only judge from the next discovery.

Looking for the companion who disappeared a year ago, although he didn't say it explicitly, several people were already hopeless, if it wasn't for Chen Cheng, it was not certain whether Bingyan and the two would survive until now, let alone the previous batch of special department members.

The only thing that makes people not give up is that where do people go without the equipment on their bodies, this suspicion cannot be explained clearly, and the final conclusion cannot be drawn.

Falling asleep with countless speculations, after waking up, Li Wei excitedly followed him out of the cave, and it was much safer to be with Chen Cheng than to stay outside alone.

Since coming here, Li Wei has felt that he is the most useless one, it is simply a drag oil bottle of the three-person team, if it weren't for him, Chen Cheng and Bingyan would have been much easier, Li Wei didn't want to do this, he had a way to deal with people, but in the face of these almost invisible, colorless, and tasteless fogs, Li Wei really didn't have any tricks at all.

Before entering the nostril cave, Chen Cheng took out a newly carved defensive magic weapon and handed it to Li Wei, in the process of refining the mist, and then taking care of Li Wei's safety, it would definitely affect the speed, and at the same time it might bring danger to himself, with this magic weapon, even if Li Wei touched the fog, he would not have to be afraid in the short term.

With better protection, Li Wei's confidence has increased greatly, he was originally an elite member of the special department, and after two days of grievances, he finally no longer has to worry about self-preservation, maybe he can help Chen Cheng at a critical moment.

With yesterday's experience, Chen Cheng knew that the further he went, the more fog he had, and the vicinity of the cave entrance was almost not much different from the outside, and he would rarely encounter fog.

Chen Cheng cooperated with Ice Flame, refining a ball of ordinary-sized mist would take four hours at the earliest, Ice Flame did not have much pressure to absorb cold energy, the speed mainly depended on Chen Cheng, if Chen Cheng reached the cultivation of foundation building, refining mist was estimated to be a matter of minutes.

For the sake of safety, Chen Cheng didn't dare to take the two of them away, so he found a place for the two of them to wait for him, and he ran inside alone, attracting a cloud of mist and then cooperating with Ice Flame to refine.

Using the same method, after completing it three times in a row, the vitality in Chen Cheng's body could no longer meet the needs of the next time, because the current speed was nearly twice as fast as before, and the speed of vitality consumption was very fast.

"Bingyan, let's get here today, it's not early, I need to take a good rest. Chen Cheng said.

Bingyan also knew that Chen Cheng's refining was not easy, so he immediately nodded in agreement, and Li Wei had a chance to interject and said, "You two practice to upgrade, I've been hungry all day, I won't be like this tomorrow, right?"

"Let's go back to the cave and rest first, and then I'll talk about it tomorrow, if you have the strength to resist the fog, I'd like to take a look inside, maybe I'll find something else." Chen Cheng patted Li Wei on the shoulder and said.

"This ...... Or I'll get out first. Considering his situation, Li Wei replied dejectedly.

"Let's talk about it later!"

After returning to the cave, after discussing for a long time, he didn't decide on the next good way to deal with it, Chen Cheng just wanted to go back to Linglong Tianfu to replenish his vitality, so he hastily ate something and went back to the tent to rest.

After midnight, Chen Cheng took advantage of the two of them to escape into the Linglong Heavenly Mansion, with hairballs to guard for him, so he didn't have to worry about his secret being exposed.

He didn't practice for two days, and after entering the space, Chen Cheng wanted to sit down and practice immediately, but Lao Jin ran over and circled around him.

Lao Jin has lived in the space for more than a year, although he can't speak, he can understand Chen Cheng's human language, and his wisdom is no worse than that of ordinary **-year-old children, when Chen Cheng was cultivating, he had never been harassed, so today's performance is a little abnormal.

"What do you want? Chen Cheng didn't understand what Lao Jin meant, and thought that he had a peculiar smell on his body, so he raised his arm and sniffed it as he spoke.

"It can't be because of refining demonic qi!" Seeing Lao Jin crying at him, Chen Cheng's heart moved, and such a thought suddenly popped up in his brain.

If Lao Jin reacted to the demonic energy, he should have behaved when he was released yesterday, and it really made people wonder why Lao Jin reacted so strongly.

"Maoqiu, is there anything different about me than usual?" Seeing that Lao Jin's expression was abnormal, and Maoqiu also came to join in the fun, Chen Cheng took the opportunity to ask.

After the hairball circled around Chen Cheng, he said, "It's the same, maybe Lao Jin hasn't seen you for two days." ”

Chen Cheng didn't speak, but he understood that Lao Jin would never be as Mao Qiu said, and it was the same if he didn't take care of Lao Jin for a few days before.

After trying to communicate with Lao Jin for a while, Chen Cheng still couldn't find the crux of the problem, Lao Jin finally left after pestering for a while, and Chen Cheng could finally cultivate with peace of mind.

"Huh?" Holding the spirit stone in his hand, as soon as he began to cultivate, Chen Cheng immediately noticed the difference from the past, he found that the speed of absorbing the spiritual energy was much faster, and it was easy to refine and absorb, Chen Cheng couldn't help but be overjoyed.

I have always been dissatisfied with the speed of promotion, mainly because the speed of refining spiritual energy cannot keep up, there are tens of thousands of spirit stones in the space, Chen Cheng does not need to worry about cultivation resources in the short term, as long as he can build a foundation as soon as possible, everything else is secondary.

Time passed quickly, before dawn, Chen Cheng used up two spirit stones, and the vitality in his body could be considered saturated, and his cultivation was also one step closer to the seventh layer of qi training, if nothing else, at most, in one month, he would be sure to successfully break through.

The unexpected gain made Chen Cheng always smile on the corner of his mouth, and before leaving the space, Lao Jin ran over again, screaming and jumping non-stop, until Chen Cheng promised to take him out later.

Coming out of the space, it was still pitch black all around, just after completing his cultivation, Chen Cheng did not feel the slightest sleep, lying on the moisture-proof mat and recalling the encounters of the past two days, guessing the origin of those strange fogs.

The terrain here is indeed very similar to a huge head, if the place where it lives is made of ears, the proportions of the ear canal don't seem to be right, and this kind of thinking Chen Cheng always feels too crazy, a head is so big, isn't the body more than ten kilometers long, how is it possible.

If you really want to find out these secrets, you either have to enter the brain, or clean up all the covering on the ground, but no matter which way, it is not something that Chen Cheng can do, and the only hope is to try to go down the cave during the day to see if he can find out any secrets.

Unconsciously, another two hours passed, Chen Cheng heard the sound of Bingyan and the two of them washing outside, Chen Cheng was there, the living utensils were quite complete, except for not being able to take a bath, almost everything else could be satisfied, after eating, Li Wei once again proposed the idea of evacuating first, Chen Cheng did not object, as he himself said, staying is also a burden.

With Chen Cheng's magic weapon for self-defense, as long as Li Wei does not approach the several places where the fog appears, there is absolutely no problem in surviving in the jungle, so the two sides agreed on a place to meet, and for three days, Chen Cheng handed him a bag of food and drinking water, and then left with Bingyan with confidence.

"Let's go inside a little further and see if we can find anything else, but we really can't come back and continue refining the mist. After returning to the cave, Chen Cheng said to Ice Flame.

Ice Flame nodded, "If that's what you think, wouldn't we fall into the giant's mouth if we penetrate here?" ”

"If I had this ability, I would have drilled into my brain by now, and I don't have to think about it, I know that there will be good things in that place, and the brains of giants have already become spirit stone mines. Chen Cheng said exaggeratedly.

"What is a spirit stone?"

"Uh...... Let's go, I'll explain it to you when I have time. ”

Chen Cheng continued to walk forward with the ice flame, he knew that the end of this road was connected to the Hu Bo outside, and he walked on the other side to search again to see if there were any mistakes or omissions.

What disappointed Chen Cheng was that it took nearly two hours to shake off the entanglement of countless clouds of mist, but the two of them didn't find anything, so they had no choice but to return to the starting point to refine the mist honestly, but before refining, he ran out alone, and only returned after more than ten minutes, and Bing Yan did not doubt Chen Cheng, because Chen Cheng had a chance if he wanted to harm her.

After cultivating for a night, the speed increased a little when refining the mist again, Chen Cheng was also a lot smarter, every time he finished refining a cloud of mist, he would hold the spirit stone in his hand and restore it to the best state, and the ice flame only then knew what the spirit stone was.

Cycle after week, at the end of the day, Chen Cheng and Bingyan actually refined six clouds of mist, and then they returned to the Ear Cave to rest again.

This was the first time Chen Cheng had been alone with a girl in the wild, and Bingyan was still an absolute beauty, but Chen Cheng didn't have the heart to think about it, almost the moment he finished eating, he got into his tent without even a second of delay.

"Maoqiu, you said that after we leave, Lao Jin will not be in danger, right?" After getting into the tent, Chen Cheng couldn't help but ask.

Even if you both have something, Lao Jin is sure to be fine, you haven't seen the speed at which the guy absorbs the mist, almost as soon as he pouts, the mist is all inhaled into the stomach, there is no need to refine it at all, and he doesn't know where to hide it when he gets in, it's the same as no reaction.

During the day, Chen Cheng ran out once, that is, to release Lao Jin at that time, because the nostrils cave corresponded, Chen Cheng and Bingyan only chose one side, so Lao Jin on the other side Bingyan didn't know the situation at all.

Daring to let Lao Jin go in alone, it was also Chen Cheng who dared to do this after seeing this guy's ability, but he didn't expect Lao Jin's appetite to be so big.

"I didn't expect to be picked up by this guy, I knew that I had this ability, and I should have let Lao Jin out on the first day. Chen Cheng smiled beautifully.

Whether it is a hairball or Lao Jin, they are Chen Cheng's good helpers, their strength has increased, and the help to Chen Cheng is even greater, he has been troubled because he can't find something useful to Lao Jin, and now he happened to be sleepy and met the pillow, what do you want.

There was nothing to say all night, when the next morning, Chen Cheng and Bingyan entered the cave again, and until they reached the end, that is, the place connected to the lake, they didn't encounter a cloud of fog, Chen Cheng smiled and didn't say anything, but Bingyan wondered, she had seen countless fog the day before, he and Chen Cheng were forced to only dodge, why did they say no overnight.

Bingyan didn't pay attention, Chen Cheng's face suddenly became nervous, "Maoqiu, are you sure that Lao Jin is not in the passage on the other side?"
