The two have had a tacit understanding for many years, and Chen Feng naturally knew that Li Cheng was worried about himself so he took over the job of exploring the way. As a brother, Chen Feng naturally won't say much, and he is also quite confident in Li Cheng's defense, at least, among all the professionals at the moment, this guy is the strongest MT, of course, this strongest is only on the surface, as for those masters hidden in the crowd, it is unknown.

As soon as he walked into this building, Li Cheng felt as if he had passed through an invisible barrier, and the scene in front of him also surprised Li Cheng.

It doesn't look as small as it looks from the outside, and when you look at this building from the outside, it's probably only the size of a house of more than 30 square meters, but when you walk in, you find that the space inside is much larger than what it looks from the outside, at least nearly 100 square meters. And from the outside, there is nothing in this sandy land, and after Li Cheng came in, the original sandy land became a round inscription stone slab, and this stone slab is a whole, without any splicing gaps.

Chen Feng and Fang Lei, who were standing outside the building, were also frightened, because Li Cheng stepped into the scope of the building and disappeared in front of the eyes of the two, and Chen Feng, who was in a hurry, immediately wanted to follow and take a look, if Fang Lei hadn't hurriedly grabbed him, he was afraid that he would have rushed in.

"Boss, don't be impulsive, wait first." Fang Lei reminded.

Due to the magician's sensitivity to magical energy, Fang Lei didn't find any disordered magic fluctuations when Li Cheng entered the building, so he believed that Li Cheng didn't necessarily have something wrong.

He ...... This ......" Chen Feng was so anxious that he didn't know what to do.

"Don't worry, the magic fluctuations just now are very smooth, and there shouldn't be any danger. Let's wait for a while, if Boss Li hasn't come out in five minutes, it's not too late for us to go in. Fang Lei grabbed Chen Feng's shoulder and said.

What's funny is that as soon as Fang Lei's words fell, Li Cheng jumped out of the gap between the stones.

"That's awesome." Li Cheng said with some excitement.

"Dead fatty, why did you just disappear? I'm scared to death, what the hell is in there? Chen Feng said angrily in shock.

"Disappear? Can't you see me? But I can see you. Hey, don't talk about it, let's go in and have a look, it's so mysterious. Li Cheng didn't explain too much, pulled Chen Feng and ran towards the building.

"Look, there's a lot of space in here than it looks outside, and besides, this ground, you see, what kind of stone is this, such a big piece is actually a complete stone. Although I don't recognize the inscription carved on the ground, I'm sure it's definitely some kind of formation. And you look at the middle of this. Li Cheng pulled Chen Feng to the middle of the round stone slab, pointed to the ground and said.

Chen Feng looked at it, there were three circular holes on the ground, the holes were about the size of a baby's fist, the three holes were arranged in an equilateral triangle, and there were three inscription lines connecting the three holes together, it was obvious that there were three spherical objects missing here.

"Brother Feng, look, these three holes, I guess they must be put some spirit stones or something, and then they can open the formation. Just don't know what to put in. Li Cheng said.

"Well, but we can't be sure that this must be a teleportation array, if it's any other formation, if it is accidentally opened, it will be worth the loss." Chen Feng said.

"Boss, have you noticed that this is ...... It seems to be dry. Fang Lei on the side said suddenly.

"Huh? If you don't say it, I really didn't pay attention. Chen Feng squatted down and touched the floor, there was really no moisture at all, and the inscription stone on the ground was also dry.

"So, the place we just came in should also have a barrier to isolate the seawater." Chen Feng said.

"Not only that, here we can see the scene outside, but the outside can't see the inside, just like that ......" Li Cheng couldn't remember for a while, what this thing looked like, and paused.

"One-way mirror." Fang Lei added.

"Yes, it's like the one-way mirror on TV in the interrogation room where the police interrogate prisoners." Li Cheng gave Fang Lei a thumbs up and said.

"Also, you can't use Waralliance communication yet. I just tried it and sent a message to those at the mouth of the canyon, but no one responded. Fang Lei continued.

"Huh? So godly? Could it be that this place belongs to a separate space? Can't be counted as a secret area? Chen Feng said in surprise.

"Then I don't know. But, Boss, isn't it time for us to move on? It doesn't seem like there's much use in staying here. The people outside are still waiting for our news. Fang Lei said.

"Yes, you can't waste time here, let's go." Chen Feng nodded in response.

Although there are nearly 100 square meters of space here, it can be seen at a glance, and after not finding anything valuable, the three of them walked out from the place they had entered before, and at this moment, no one found that two light blue inscription imprints the size of thumbs were quietly imprinted on the backs of Chen Feng and Li Cheng, but the two did not feel the slightest.

But as soon as they stepped out of the teleportation array, two sharp blades of light slashed down on the top of the trio's heads.

"Be careful...... Chen Feng and Li Cheng reacted almost at the same time, and issued a warning loudly.

Li Cheng, who was a little late, only had time to raise his shield to block, but Chen Feng kicked Fang Lei out of the side with one kick, and then raised his knife to block.

"Wow......"

The two impacts overlapped, and Li Cheng was hit by the light blade and almost didn't catch it in one breath, but fortunately, he only took half a step back.

On the other side, Chen Feng was not so lucky, although the light blade hit the wind knife and was cut in half by the blade, the castration was still unabated, and it slashed at Chen Feng's body, fortunately, Chen Feng had already put all the red armor on his body after entering the first bend of the canyon, and with the protection of a full set of armor, this blow was blocked by the red armor, but the powerful impact still made Chen Feng feel a tingling pain from the sternum cone.

At this time, Fang Lei, who was kicked to the side and was lucky enough to dodge the light blade attack, got up from the ground. Two humanoid monsters holding three or four meters long giant axes stood ten meters away from the front of the strange building, and the giant axes in their hands were still slowly being withdrawn.

Seeing this scene, Fang Lei didn't say a word, raised his hand and threw it at the feet of the two monsters, and then Fang Lei's hands were sealed, ready to start using the gravity technique to restrict the actions of the two monsters.

Chen Feng was blasted away by the light blade and directly hit the boulder outside the strange building, and Li Cheng had just recovered his strength, the two humanoid monsters holding the giant axe did not seem to be affected by the swamp technique at all, and after putting away the giant axe, they raised their feet and walked towards Fang Lei.
