In fact, the easiest way to return is to use a personal teleportation stone, but this thing, now with one piece less than one piece, unless it is an emergency, it will not be used easily. Because even if they are such a big alliance as the Light of the Last Days, there are not many teleportation stones left, not to mention, this time the team is full of more than fifty people, if they use teleportation stones, it will be a waste of more than fifty.

There was no need to waste such an important material, Chen Feng decided to kill all the way back. But fortunately, everyone has already broken through this road once, and it can be regarded as a familiar road to deal with.

It took about half an hour for everyone to pass through the nearly five-kilometer-long open land and come to the canyon, and when they passed through the canyon, Chen Feng stopped everyone, because he still had something to make sure again.

In the middle of the canyon, in front of the strange building.

"Brother Feng, are you sure you want to do this?" Ding Qingyue asked.

"Don't worry, there are so many of us here, you can still see us after you go in, as long as you find that there is a fight outside, you can come out." Chen Feng patted Ding Qingyue's shoulder and said.

"I didn't mean that, I mean, what if your guess is wrong, and as soon as I go in, there is more than one giant axe monster that comes out of the outside?" Ding Qingyue said with some concern.

"Don't worry, in order to prevent this, I let them all stand outside the entrance, before I came in with the second grandmother and Fang Lei, and only refreshed the two giant axe monsters, now the three of us stay here, with the BUFF blessing of Yiyi, even if we brush out three giant axe monsters, we can carry it for a while, and when you come out, let them come in to help, three giant axe monsters, more than fifty of us can't handle it." What's more, if I'm not mistaken, I'll definitely only come up with one. Chen Feng said.

"Alright then, you two are ready, I'm in." Ding Qingyue took out the blue feather crossbow, glanced at the two of them, and walked into the strange building.

Seeing Ding Qingyue disappear, Chen Feng and Li Cheng hurriedly turned around and became fully vigilant. Time passed, and after about a minute, a vague figure suddenly appeared in front of the two of them out of thin air, Chen Feng and Li Cheng glanced at each other, and without saying a word, they raised the sword and shield in their hands and rushed forward.

The tragic giant axe monster, before he could even see the enemy in front of him clearly, was stunned by Li Cheng's shield strike, and then Chen Feng followed it with a few knives and split it into a pile of parts. The giant axe monster that has been sneaking up on everyone until he dies never thought that he would be attacked one day.

"It seems that I guessed correctly, this thing, only people above level forty will brush it out, and moreover, how many people go in, it will brush out as many as it is, it seems that this thing, what kind of test or something like that." Chen Feng said.

"It must be, or this giant axe monster won't explode anything, only this thing." Li Cheng pointed to the stone that was still floating in the air and said.

When Ding Qingyue saw the two of them doing it, he had already reflexively ran outside, but all he saw was the scene of the giant axe monster being rubbed and abused, and when Chen Feng picked up the unknown guardian crystal dropped by the giant axe monster, Li Cheng finally remembered what this thing looked like.

"Wait, Brother Feng, could this thing be the stone to be used in that teleportation array?" Chen Feng was about to put the Guardian Crystal into the ring, when Li Cheng grabbed his hand and shouted.

"When you say that, it's a bit like that." Ding Qingyue also came up, looked at the guardian crystal and said.

"Whether it's true or not, try it and find out." Chen Feng took the Guardian Crystal and turned around and walked towards the strange building.

"Eh, wait...... Are we just going to go in? Li Cheng pulled Chen Feng and asked.

"Isn't that what happens? Waiting for dark? Or wait until you're done eating? Chen Feng tilted his head and asked.

"I'll go, you know what I'm talking about." Li Cheng said with a look on his face, I am convinced of you.

"It's okay, just the three of us go in, no matter how you brush it, just brush the three giant axe monsters out, let Haozi and them stay outside, it'll be fine." Chen Feng said as he beckoned to Yang Tianhao, who was watching from the entrance.

When everyone arrived, Chen Feng explained to them, and then took Li Cheng and Ding Qingyue into this strange building again.

It wasn't the first time the three of them had been here, so they didn't pay any attention to their surroundings, but walked directly to the center of the inscribed floor. Chen Feng took out a Guardian Crystal and made a gesture on the three holes in the center, and then gently put it in.

"Click......"

A soft sound came from the ground, and the Guardian Crystal, which was originally the color of a stone, suddenly lit up with a faint blue light. The three of them glanced at each other, although they didn't speak, but their eyes were already full of joy, Chen Feng took out the other two guardian crystals from the ring without hesitation and put them on.

The moment the Guardian Crystal was put up, the entire Deep Sea Path suddenly shook. The shock was not so strong that even some distracted people didn't notice it. But on this inscription stone slab, Chen Feng and the others clearly felt the vibration from the ground.

Immediately after, the three guardian crystals lit up at the same time, and three blue lines, like liquid, flowed out of the guardian crystals, scattering along the inscriptions on the stone slabs, and in less than five breaths, the entire stone slab was filled with blue liquid.

After the blue liquid filled the last inscription, the stone slab on the ground suddenly cracked, turning into three concentric circles, Chen Feng and the three of them stood on the concentric circle in the middle, and the second concentric circle began to rotate clockwise. The third concentric circle rotated counterclockwise, and the slate rotated faster and faster, and the three of them were at a loss.

Suddenly, the surrounding area of the central stone slab was full of light, and a circle of light rose up to the sky, enveloping Chen Feng and the three of them inside.

People outside the building only saw that a pillar of light rose from the center of the building and disappeared in a flash, but they didn't know what happened, after the pillar of light disappeared, Wang Xiaoling asked Fang Lei to go in to investigate, and the results made everyone surprised, Chen Feng and the three disappeared.

At the entrance of the canyon, thirteen tired figures sat together and rested for more than an hour, and everyone's spirits finally recovered.

"Where do they go, you say?" Lin Bei said out loud with a gentle wipe of the dagger in his hand.

"Where to go? We haven't been to the other side of the canyon, and who knows where they've gone. Xie Tielin said.

"You say, will they kill all the way to the boss of the secret realm final clearance?" Lin Beiyong asked again.

"I admit that Chen Feng has a strong team and good discipline, but that doesn't mean they are invincible. You must know that even the last level of the Tomb Abyss requires the alliance of all major war alliances to break through, this is a stronger secret realm than the Tomb Abyss, how can he only rely on more than fifty people to break through. Wu Jie said lightly.

"But, after so long, if they don't have the ability to go to the end, it's almost time to turn back." Bai Lingwei leaned on her companion and looked at the entrance of the canyon and said weakly.
