The black unicorn took Lin Changsheng to the stone wall of the Death Gate of the Bagua Palace.

It sniffed around with its nose, then took a few steps forward, pressed its front paws against a floor tile, and looked back at Lin Changsheng.

Lin Changsheng strode forward, and the black unicorn removed its front paws.

He looked at the floor tiles, and then knocked and probed, there was no hidden grid mechanism here, and looked back at the black unicorn, the black unicorn 'looked expectant', as if waiting for Lin Changsheng to open it quickly.

Lin Changsheng's eyes narrowed slightly, although there was no hidden grid mechanism here, it was impossible for the black unicorn's sense of smell to go wrong, it felt that there was something here, then there must be!

Moment......

Diancang used his fingers, and his two fingers pierced into the floor tile, and Lin Changsheng pulled out the floor tile with all his might.

Underneath is a black stone, about the size of a palm, carved with strange and intricate patterns, and I don't know what it is for.

Lin Changsheng carefully took out the black stone, and after observing it for a while, he didn't understand what it was.

Could it be that this is the Immortal Stone that Bolair said?

But no, even if the Immortal Stone is really in the Underground Tomb, it should be in the main tomb, how can it be in this place?

Lin Changsheng just wanted to call Ye Lin to help take a look, but when he turned around, Ye Lin and the others were all awakened at this time.

Obviously, they were woken up by the sound of Lin Changsheng pulling out the floor tiles.

Ye Lin thought something was wrong, and asked anxiously, "What's the matter, Changsheng?" ”

Lin Changsheng shouted: "I found something, come and take a look." ”

In addition to Boller, Ye Lin and the others ran quickly towards this side.

"The ghoul is healed?"

Qiu Yihan stared at the black unicorn for a while, and said, "Okay, this vitality can be compared to Xiaoqiang!" ”

When the black unicorn heard that Qiu Yihan didn't call its name, he immediately bared his teeth.

Qiu Yihan was a little confused, he didn't provoke the ghoul dog, what's going on?

Lin Changsheng gave him an answer: "I just gave it a name, it's called Black Qilin. ”

Qiu Yihan immediately said to the black unicorn: "Call your name next time." ”

When the black unicorn heard this, he gave up.

Ye Lin was stunned when he saw the black stone, and asked, "How did you find this thing?" ”

"The Black Kirin found it."

Lin Changsheng replied truthfully.

"Stones?"

When Bolair heard the stone, he immediately got up and ran over and asked loudly, "I'll see if it's an immortal stone." ”

Ye Lin didn't want to show him, but it was too late, and Bolair had already seen it, he sighed in disappointment and said, "It's not ......"

Immortal Stone is not like this at all.

Chen Xue asked, "Ye Ju, do you know what this thing is?" ”

"I don't know."

Ye Lin shook his head, looked at the black stone, and continued: "But this stone should not be an ordinary stone. ”

"You're talking nonsense......"

Qiu Yihan rolled his eyes and said, "How can the things buried in the Bagua Hall be ordinary?" Maybe this thing was hidden by Qiu Chuji, since he can calculate the matter between Liu Bowen and Hou Ye in the future, then he must also be able to calculate that Hou Ye can find this stone, right? ”

Uncle Dog nodded in agreement and said, "You finally have an IQ online once." ”

Qiu Yihan said helplessly: "Uncle Dog, are you praising me or scolding me?" ”

"It doesn't matter what it is, let's take it with you."

After Chen Xue finished speaking, Ye Lin felt reasonable, so he asked Lin Changsheng to put it in the equipment bag.

The people were a little hungry, and they sat down around and began to eat and drink.

The black unicorn could also eat other things, and Lin Changsheng fed it more than a dozen packets of compressed biscuits and two bottles of mineral water before feeding it a two-point full.

Although it was hungry, it did not eat.

The Black Qilin was very smart, it knew the importance of food and water in the Underground Tomb, and instead of continuing to waste Lin Changsheng's food, it was better to wait until it came across the white-haired corpse to eat enough.

After all, there's no shortage of stuff here.

After eating and drinking, everyone cleaned up the garbage and continued to walk.

There was only one way to the front of the Bagua Palace, and when he came to the entrance of the passage, Qiu Yihan once again took out his mechanical mouse to explore the way.

In less than two minutes, the mechanical rat was back.

After observing the route on the remote control, Qiu Yihan looked at Lin Changsheng and said, "Master Hou, this passage is almost a straight line, about six or seven hundred meters long, and up to seven meters wide. ”

"Okay."

Lin Changsheng nodded.

Qiu Yihan replaced himself with a slow-moving mechanical mouse and continued to explore the way.

Soon, the slow-moving mechanical rat also returned, Qiu Yihan observed the traces on the mechanical mouse, got up and said, "There are no traps." ”

Ye Lin asked, "Is it accurate?" ”

Along the way, almost every passage was in danger, and suddenly there was no danger, and he was a little uncomfortable.

Uncle Dog burped and said, "Ye Ju, it's good to be cautious, but if you're too cautious...... It's a bit too much. ”

"Let's go, it's still the old rule, I'll go ahead."

Lin Changsheng strode into the passage, and the Black Qilin, Ye Lin and the others followed.

The stone walls in this passage are polished very smooth, and after nearly two hundred meters, murals begin to appear, showing a group of people on the grassland, some with bows and arrows in their hands, and there are many eagles in the sky, and they are preparing to bend their bows and shoot eagles.

The mural lasted for nearly three hundred meters, and after reading it, Ye Lin said: "It's a condor drawing, but there is no main owner in this picture." ”

The main person here is naturally Genghis Khan.

Soon, the crowd reached the end of the passage, but there was no way to the end!

This time, the way out is not blocked by a stone wall, but ...... Scar!

Lin Changsheng stepped forward and glanced below, the cliff didn't know how deep it was, it was definitely not man-made.

The whirring wind came out from the cliff, but the strange thing was that they didn't hear the wind in the passage, and as soon as they left the passage, the wind was unusually harsh.

About 20 meters in front of this cliff is the continuation of the tomb.

Chen Xue asked softly, "Was this cliff caused by the change in terrain after the construction of the tomb, or was it there before?" ”

"It's been before."

Uncle Dog opened his mouth and continued: "Before I came, I saw the topography of Liupan Mountain, and it didn't change much, if this cliff was changed after the construction of the tomb, such a big cliff, the outside will definitely be more obviously affected. ”

Lin Changsheng said: "This is the use of natural hazards, although they all belong to the earth tomb, but there are natural hazards across the road, just like the 'moat' outside the royal city." ”

Qiu Yihan asked, "Master Hou, that is to say, as long as we pass here, we will enter the central area of the Earth Tomb?" ”

"Soon, after all, in addition to the 'moat', there is also the 'city wall' blocking the way, and only after the 'city wall' can you reach the central area."

Lin Changsheng nodded, looked at Uncle Dog, and said, "It's time for you to appear." ”
