Qi Yuancheng and the tiger joined forces to attack the illusion and found a metal door.

"This, this is the door to the passage?" Kwon Sung-ho quickly went to the door to take a look and came back, a little incredulous.

At this moment, a long, low sound came clearly from the other end of the door. The whole ruins trembled slightly, and everyone noticed that dust was falling from above.

"It's the monster!" Quan Chenghao's face changed greatly, and he couldn't help but take two steps back, "Is this here going to collapse?" ”

Qi Yuancheng looked at the tiger who was still lying on the ground and couldn't get up, and said to Liu Dachao beside him: "Brother Liu, the tiger boss's condition is still unstable, so I have to trouble you to stay and take care of it first." I'll go and investigate first, so that I don't have too many dreams at night. Then, he said to the tiger: "Tiger boss, you can recover here with peace of mind first, and come to us when you have the strength!" ”

The tiger struggled to get up, but he couldn't move, so he had to nod slightly.

Liu Dachao also: "Yuancheng, don't worry." In case anything goes wrong, I'll do my best to get out of here with the Tiger Boss. Right, do you have any problems with Yuancheng's past investigation? ”

Kwon Sung-ho hesitated, still: "I, it's okay for me to inquire about the situation, but if it really starts a fight, I ......"

Qi Yuancheng: "Don't worry, we will investigate secretly and try to avoid fighting." If you are in danger, you will flee back here with all your might. ”

, Qi Yuancheng and Quan Chenghao came to the metal door. I saw that the door was rusty, and the original pattern was no longer visible. It's just that in the center of the door is a seven-sided crystal pattern.

Qi Yuancheng took a deep breath, pressed the hand that fused the source stone on the door, and pushed it slightly.

To their surprise, the door opened easily in both directions without great resistance.

When the door opened, a large cavern appeared in front of the two of them. Instead of being as dark as expected, the cave was shrouded in a faint yellow glow, revealing the scene inside.

Qi Yuancheng and Quan Chenghao were stunned by the scene behind the door. The two looked at the cave and saw that the cave was the size of two football fields, and the height was dozens of floors and nearly 100 meters high. And in the middle of the cavern, a huge creature crouched on the ground.

The creature was the size of three heavy trucks, covered in a metallic blue sheen, and had a strangely streamlined spindle-shaped head. Its body shrunk into a ball, and the shape of the body could not be seen, but Qi Yuancheng and Quan Chenghao's hearts had sunk. Because the appearance of this monster is too familiar to them, it is the strange snake that once fought with them - the ghost Jiao in the mouth of the source stone.

"Sure enough, it's the ancestor of this monster!" Kwon Sung-ho's voice trembled and said, "Yuancheng, do we really want to fight this monster?" Do you want to slip over while it's asleep? ”

Qi Yuancheng said in a deep voice: "Let's not act rashly first, I'll check it with Gu Mist first." With that, he stretched out his hand to release a wisp of dark red Gu mist, silently floating towards the giant ghost Jiao that was still sleeping.

Qi Yuancheng released several clouds of Gu mist one after another, and soon the surroundings of the ghost Jiao were filled.

"This monster is bigger than what we see." The results of the exploration made Qi Yuancheng also a little frightened, "Its body is clumped together, and once it stretches out, it will be at least one-third of the length of this cave." ”

"At the moment, though, he shows no signs of recovery. The chirp we heard just now was probably just an unconscious cry from a deep sleep. Qi Yuancheng said, and his words made Quan Chenghao breathe a sigh of relief.

"Yuancheng, since there is no danger, leave it to me next, let me go down and investigate." Kwon Sung-ho volunteered.

Before Qi Yuancheng could speak, Quan Chenghao had already jumped towards the ground below.

Qi Yuancheng saw that Quan Chenghao was so impulsive, and he also sweated for him in his heart. But he couldn't be as reckless as him, so he had to continue to release Gu mist and spread around the big ghost Jiao, just in case.

When Quan Chenghao came to the field, he did not approach rashly, but stayed cautiously in the distance, and slowly approached the sleeping big ghost Jiao with extremely slight movements.

Qi Yuancheng's Gu mist was already all over the big ghost Jiao's body, and judging from the reaction of the Gu mist, the ghost Jiao had no tendency to wake up. He had a whim, thinking that if the Ghost Jiao was a biological weapon made by Langmu, it might also be able to be controlled by his own Gu Mist.

In fact, since Qi Yuancheng accidentally obtained the corrosive ability from the Source Field Force Locust Swarm, he had rarely used Gu Mist's original ability to invade and control living beings.

Qi Yuancheng secretly said that he was too careless, so much so that he forgot about his book. He manipulated the Gu mist to invade the Great Ghost Jiao's body from various positions in its body. The infiltration of the Gu mist was unexpectedly smooth, and the sleeping ghost Jiao's defense against the outside was almost zero.

Soon, Qi Yuancheng's Gu mist walked to the upper half of the ghost Jiao's body. He found that the structure of the body in the ghost Jiao's body was completely different from that of modern creatures, not only did it have no muscles and body fluids, but it was replaced by a thick frame similar to bones to support its body, and the connection between the skeletons was some tangible and intangible chains that shimmered with ghostly light, and there were some shiny balls of light at the intersection of the chains. At the core of the ghost Jiao's head, there was a huge light cluster suspended in it, and several light chains stretched out from the light cluster to connect the light balls in various parts of the ghost Jiao's body.

"This was the most powerful weapon of the Langmu people at that time. It is also a masterpiece of their technical pinnacle. The source stone, which had been silent, suddenly connected to Qi Yuancheng and said in an emotional tone.

"Old-timer, in this case, this ghost Jiao is not a living organism?" Qi Yuancheng exclaimed, he hurriedly stabilized the Gu mist in the ghost Jiao's body, so as not to touch the mechanism by mistake.

"You're doing the right thing. Those balls of light are the core power of the Ghost Jiao's combat weapons, and once the energy is triggered, they will make the Great Ghost Jiao wake up. Source Stone affirmed, "The things you released are very wonderful, and they didn't have this kind of source field power in the Langmu era. It can be seen that you humans are indeed very different from the Langmu people of the past. When I go out, be sure to do some research. ”

Qi Yuancheng was shocked into a cold sweat. He calmed down for a moment and began to manipulate the Gu mist in the ghost Jiao's body to slowly withdraw.

"Did that companion of yours go down there? It's better to get him back. Until you are fully prepared for battle, angering this monster will only lead you to a terrible death. Yuanshi reminded.

Qi Yuancheng hurriedly looked down, only to see that he didn't pay attention, Quan Chenghao had already come to the front of the ghost Jiao, and was looking around at the huge head of the ghost Jiao.

Qi Yuancheng was anxious. He couldn't make a loud reminder, so he could only watch Quan Chenghao slowly approach the ghost Jiao.

"Heart! Don't shine on the head of the ghost Jiao! Yuanshi said suddenly.

Qi Yuancheng hurriedly put down the searchlight in his hand, he originally planned to use the light to warn Quan Chenghao.

"That's it! I'm sorry Brother Quan! Qi Yuancheng said secretly in his heart, and then he manipulated the Gu mist that was originally scattered around the ghost Jiao to enter the Zheng of Quan Chenghao's body

Kwon Sung-ho in the audience was about to reach out and touch the ghost Jiao's body curiously, but he was horrified to find that his body could not move.
