It took the Poplar Iron Bull nearly a whole day to finally determine that the towering peak was where the Immortal Cave was located.

After that, it took nearly a day to find the thorny ravine that had led up the mountain first.

Considering that they would have to pass through the extremely dangerous vampire bat cave, the brothers wanted to tie up a few torches and bring them with them, but Poplar noticed something unusual at the entrance to the ravine, as if someone else had entered the ravine.

"We passed by here a few days ago, and at that time we only pulled the thorn vines in the ditch out of the place where they settled! But in the past few days, these thorn vines should have climbed to the bottom of the ditch again! But you see these thorn vines, obviously they have just been pulled, so someone must have entered the ditch, and it won't take long to get in!" Poplar explained to Tie Niu.

"So you say, have other inverted fighters come in looking for the Immortal Cave?" said Iron Bull.

"It's hard to say!" Poplar shook his head, suddenly remembering something, and couldn't help but change his face, "It's not good, let's go into the ditch and have a look!"

"What's wrong?" Iron Bull was puzzled.

"Don't forget that Master Qiu has left a few disciples outside to answer, maybe those disciples haven't received news from Master Qiu for a few days, and they came in to look for them according to the mark of their own door! These people don't know how powerful the vampire bat cave is, if we can't stop them, I'm afraid they will die a miserable death!"

As he spoke, Poplar jumped into the bottom of the ditch, following the newly opened foothold at the bottom of the ditch, and quickly moving forward.

The Iron Bull naturally followed him closely.

Those footholds are scattered among the thorns and thorns, but with the ability of the poplar iron ox, it is naturally not difficult to walk.

Soon, the two of them bypassed a bend in the mountain, and saw that on the rocky rock in front of them, there were indeed two figures climbing upwards with difficulty.

And the direction they climbed was suddenly where the vampire bat cave was.

"Stop, don't climb up!" shouted Poplar.

The two figures on the top immediately turned around to look down, and the one below shouted, "Is it the White Hero and the Iron Hero?

As soon as Bai Yang heard it, he knew that the person who asked the question was Gao Daoren, a disciple of the three elders of the Kaishan faction.

I was about to open my mouth to answer, but unexpectedly, the mountain rock was so steep that even Master Qiu didn't dare to climb it at will.

The kung fu of these two disciples is naturally not the same as that of Master Qiu, and they barely managed to climb up with all their might.

Now turning around and talking to Bai Yang, Gao Daoren's feet slipped, and he couldn't help but exclaim, and his whole body rolled down the stone rock.

Bai Yang hurriedly flew over, took a few steps to the side of the Gao Dao man, stretched out his hand to grab the Gao Dao man, and directly led him down to the bottom of the ditch to put down.

Gao Daoren's face turned pale with fright, and Bai Yang had no time to pay attention to him, so he re-ascended to Shiyan and took Liu Daoren from above.

Sure enough, these two Taoists hadn't received a message from Master Qiu for a few days, so they followed his unique mark as a mountain opener and entered the mountain.

As for how Master Qiu sent them a message in this primeval forest, the two Taoist gods mysteriously refused to say more, and Poplar didn't ask, but just told them to quit the ravine and wait, and he and Tie Niu went to rescue Master Qiu and the others.

The two Taoists knew that they were too far behind Baiyang Tieniu, so they could only repeatedly beg Baiyang Tieniu to rescue Master Qiu and a few senior brothers, so they reluctantly withdrew from the ravine. The Poplar Iron Bull tied up a few torches and climbed the rocky rock into the vampire bat cave.

There was a smoke from the torches, so that the vampire bats did not dare to approach, and the brothers passed through the vampire bat cave safely, and then walked through the wooded Rakshasa Valley.

Those primitive Rakshasas already knew the power of the Poplar Iron Bull, and they didn't dare to harass it anymore, and the brothers arrived at the foot of the mountain where the Immortal Cave was located.

In addition to the two injured mandrills in the fairy cave, I don't know if there are any other monsters that have not appeared, so Poplar guards the rope on the edge of the cliff, and the iron ox follows the rope down to the edge of the black stone forest.

It is naturally impossible for Tie Niu to cross the Black Stone Forest alone, but the Black Stone Forest is only a thousand meters away, Tie Niu let go of his throat and shouted a few times, and immediately came a cheer response from Xiang Aiguo and others.

After that, Tie Niu climbed a large stone pillar and held a flashlight to guide the way to Xiang Aiguo and others.

Xiang Aiguo and the others smoothly passed through the black stone forest to meet the iron bull, and then climbed the rope up the cliff more than 20 meters high.

Xiang Aiguo and the others had already eaten all their dry food, but the translucent small fish in the dark river was not only non-poisonous, but also delicious and sweet, so the four of them did not starve.

So a few people didn't have to do another rest, they directly followed the poplar iron ox out of the fairy cave, went down the steep peak through the Rakshasa Valley, and then made torches to enter the vampire bat cave.

Vampire bats are indeed afraid of fireworks, and each of the six people in the group held two torches in their hands, but not a single vampire bat attacked from beginning to end.

After passing through the thorny ditch and meeting with Liu Daoren and Gao Daoren, Liu Daoren and Gao Daoren heard that the other four brothers were all dead, and they couldn't help but cry bitterly.

A group of eight people walked through the primeval forest and reached the edge of the forest, where they were greeted by the other two mountain pioneers who were responsible for answering.

Ten people arrived in Meixian safely, and the head of Qiu ordered a few disciples to return to the main altar of Kaishan first, and he still took Xu Daoren, who was waiting in Meixian, to Xi'an with Baiyang Tieniu.

Ding Lingling and Hongxing's bodies have completely recovered, and when they heard that Poplar Tie Niu was back, they were excited to welcome them out.

From the two of her, she learned that Chen Xiaopang had been discharged from the hospital, but her body had not fully recovered, so she temporarily returned to her hometown to recuperate.

waited until Ding Sicheng met Master Qiu, and Poplar Tieniu entered the office to report to Ding Sicheng.

What Bai Yang didn't expect was that when he talked about the alien bones found in the bronze box and the written records about aliens found from the inner wall of the sarcophagus, Ding Sicheng's face changed drastically, and he stood up and paced around the room.

Bai Yang had to ask, "Uncle Ding's appearance, could it be that he has also encountered something about aliens?"

"I haven't encountered it, but ......" Ding Sicheng paused for a moment before finishing his words, "Ten years ago, the Shaanxi archaeological team found a strange tomb, which was on the top of an extremely steep stone peak. This pinnacle stands straight on all sides, just like a large stone pillar standing upright, not to mention ordinary people, even the top martial arts masters, it is impossible to climb up! However, the height of this pinnacle is limited, and from the edge of the cliff of a nearby peak, you can see the situation on this pinnacle. A member of the Shaanxi archaeological team, when he was investigating in the mountains, accidentally found that there was a not too small building on this stone peak from the edge of the cliff. This is a very strange and very important discovery, imagine that it is still difficult for modern humans to climb this stone peak, who and when actually built such a building on the top of this stone peak?"

Ding Sicheng paused a little when he said this, causing Tie Niu to speak: "It's really strange enough, if I see it, I have to climb the stone peak to find out anyway!"

"Yes!" Ding Sicheng nodded, "The archaeological team member who discovered this strange scene at that time was also full of curiosity and excitement, but he could never climb the stone peak, so he could only go back and report to the leader." In the end, after the leader took several experts to conduct field investigations, he invited a rock climbing expert from abroad, first asked the expert to use rock climbing tools to climb the stone peak, and then the archaeological team members climbed the stone peak along the rope left by the rock climbing experts, and conducted a field investigation of the buildings on the peak. It was quickly determined that it was an ancient tomb, and the year of its construction should have been a thousand years ago, during the Song Dynasty. The burial chamber is arched and circular, and the indoor area is not large, only a dozen square meters. The whole burial chamber is made of stones, but the stones are large and small, round and square, and between the stones, there is not even a thin blade that can be inserted......

That's all he said, as Poplar exclaimed, "How is this possible?"

"Yes, how is this possible?" Ding Sicheng shook his head and sighed, "At that time, all the archaeologists were stunned, just like you, they unanimously thought that it was impossible! Not to mention the Song Dynasty, even modern people are not capable of putting these large and small round stones together so closely and building them into an arched tomb! This tomb alone has refreshed the cognition of the archaeological community and subverted all the archaeological consensus from ancient times to the present!"

Ding Sicheng paused again. Poplar had to ask, "What about then?"

Ding Sicheng shook his head and said, "The strangest thing is still in the tomb! There was originally a white marble sarcophagus in the tomb, but the inside of the sarcophagus was empty, and the lid of the sarcophagus was smashed into pieces......

"That must have been done by the bastard in black, and he is the only one who has the ability to climb the stone peak!" Iron Bull blurted out.

"Yes, now we think it was the man in black who did it, but at the time, no one knew what was going on!" Ding Sicheng sighed and shook his head.
