Xiao Hei pierced into the ground, skimmed through the pitch-black soil, searched carefully, and after dozens of minutes, it was blocked in its way. In front of him is an artificially built bluestone, Xiao Hei can't pass through, so he turns around this bluestone, which is a road that stretches down diagonally.

Xiao Hei followed the edge of the bluestone road, deep into the ground, until a few hundred meters later, the road was connected to a huge object made of bluestone, which could not be entered, and Xiao Hei had to tell Chen Mian what it saw.

"Can't get in? Then you look for the entrance of the Yongdao", Chen Mian frowned slightly, Xiao Hei's virtual body skills have always been invincible, but he didn't expect to encounter obstacles this time, Chen Mian wanted to wait for Xiao Hei to find it and directly teleport her in, but now it can't be done.

After a while, Xiao Hei appeared on the magic flying carpet, and Chen Mian followed Xiao Hei's instructions and came to the sky above the entrance of the Yongdao, "Dig more than ten meters down from here to get to the entrance, but there is a stone gate there that can't be opened", Xiao Hei said.

Chen Mian estimated that this door needed something specific to open, she didn't know anything about it, and Gu Yanzhi didn't mention anything about it.

She had to wait for Gu Yanzhi and them to find this place, this place is halfway up the mountain, and there is no difference from other places on the mountain, Xiao Hei said that there is an oval bluestone under the fallen leaves here, which is the same as the material of the road.

Seeing Gu Yanzhi and them passing by countless times, Chen Mian couldn't wait to tell them directly, and after thinking about it, while they were sleeping at night, Chen Mian evenly picked up a layer of fallen leaves here, revealing a little tip of the bluestone.

The next day, the shortest of the seven, nicknamed Bang, walked through the area, his foot just touching the tip of the bluestone, and the hard touch stopped him.

Bangzi squatted down and picked up the fallen leaves around him, and even dug up a lot of soil, but still did not completely dig out the bluestone, and the part hidden in the ground became larger and larger.

He quickly took out the walkie-talkie on his body, "Do you think that stone will be buried in the ground?" ”

"It's possible", "Then we won't dig the mountain again", "The stones will definitely not be small, and don't let go of the small stones in the ground"...... After a while, Gu Yanzhi's voice came, "Bangzi, did you find something?" ”

Bangzi was still digging the surrounding soil, digging deeper and deeper, "Boss, come quickly, I seem to have found it." ”

All the people scattered in the mountains gathered here to help dig up, and the stone gradually revealed its full appearance. It is an oval bluestone, standing upright, with a base underneath.

They moved the tent here and continued to dig, and Chen Mian waited very expectantly until they dug the bluestone gate.

This door is unpretentious, and there are not even patterns on it, let alone words. The bluestone used in a large area feels like an ordinary stone, and I can't see anything special, I don't know if it's the stone itself or something else that makes Xiao Hei's virtual body skills hit a wall.

Gu Yanzhi and the others were also helpless against this door, they couldn't push it open, they couldn't smash it, and they couldn't blow it up. A group of people stood in front of the door, looking for possible mechanisms.

"Where's the old fishman?" "Old fish, where are you...... The old fish suddenly disappeared in front of the door, startling the whole team, and their shouts went unanswered.

At this time, the old fish who suddenly appeared in the bluestone corridor was also frightened, he just accidentally scratched his hand on the stone gate, but found that his blood was sucked into the stone gate, and then in the blink of an eye, he arrived in this oblique downward corridor.

The small stone on the top emitted a milky white light, illuminating the stone steps deep into the ground, and there was no end in sight, and before he had time to look more, the old fish heard the call of his teammates from behind.

The stone door behind him looked the same as outside, and still couldn't be pushed open, Lao Yu shouted, "I'm here, ...... with blood" The only thing that responded to him was the echo in the corridor and the voice of his teammates calling him outside the door, and even the intercom was a murmur.

The old fish was very anxious, although there was no danger for the time being, but he didn't carry much food with him, he shouted that he was tired, he sat on the stone steps at the door and thought bitterly, "How can I get out...... That's right, blood", he slapped his thigh, quickly cut open the wound that had congealed again, and pressed it to the stone door.

The blood soaked into the stone gate, and the old fish disappeared into the corridor.

"I'll go, I'm scared to death", Bangzi was knocked away by the old fish that suddenly appeared, "Old fish, what happened to you just now"......

The old fish that came out quickly explained the situation, and everyone scratched their fingers and tried it once.

"Go up first and bring the supplies", Gu Yanzhi made arrangements in a loud voice.

Chen Mian was already wearing a ratskin cloak at this time, hiding in front of the bluestone door, she quietly bit her finger and pressed it on the stone door, and the crow who stayed behind the stone gate did not see the blood stains that suddenly appeared and disappeared in the corner of the stone gate.

After entering the corridor, Chen Mian wanted to call Xiao Hei out of the attached space, but found that there was a layer of obstacles, Xiao Hei and Xiao Gelin could not come in, but other things could be taken out, and even she herself could enter the attached space and reappear in place.

"Is it because it's not human, or because it's not bloody?" Chen Mian thought about the difference between Xiao Hei and his own, and after using blood to go out, let Xiao Gelin, who could be invisible for a long time, try to see if he could enter with blood.

Xiao Gelin's blood was not absorbed by the bluestone gate, but fell to the ground in repulsion, "Do you need human blood?" Chen Mian took Xiao Gelin back to the attached space and entered alone again.

Chen Mian was worried that there would be a mechanism, so he clinged to the wall of the corridor, using his hands and feet together, and went down the stone steps, it was difficult for him to occupy only the corner of the edge of the corridor with the size of a human, if only humans could enter, then walking from the edge was the safest for Chen Mian, who was now a small mouse.

After walking dozens of steps in one breath, Chen Mian faintly heard footsteps behind him, stood on his two hind legs and looked back, the seven people seemed to have already come in, and they also chose to walk against the wall like themselves, the speed was very slow, and they were always vigilant around.

The time for the stealth technique was limited, so Chen Mian didn't care about them anymore and hurriedly accelerated down. The road was bottomless, but there were no accidents along the way, and even the seven-person team behind them was not harmed in the slightest.

Although the speed of those seven people was not fast, Chen Mian was now a small short leg, and the height of the steps was not convenient for her current size, and the speed of moving forward was not much faster than them.

When he turned around, he couldn't see the stone gate that came in, but the figures of the seven people were still faintly visible in the milky white light.

Before the stealth effect disappeared, Chen Mian returned to the attached space, and after taking off the cloak, he put a light body technique on himself, increasing his agility by four points, and then used the stealth again to put on the cloak and return to the corridor.

After this delay, the people behind her were closer to her, but after four more points of agility, Chen Mian's speed was much faster, and the distance was a little farther away.

I don't know how long I walked, but Chen Mian finally faintly saw the end, a doorway slightly smaller than the Yongdao, with glowing stones inlaid on both sides.
