Just as Xu Jianguo was daydreaming, the masters of Bureau 749 were already ready to enter the third stone gate of the underground space of Langge Village, Dianzhou.

Because during the preparation time before starting the mission, the investigators from Bureau 749 stationed in Lange Village had entered the underground space many times to investigate the situation.

After several attempts, everyone was at a loss as to how to open the third stone door because it was located underground. Considering the structure and cultural relic protection issues, no one dared to use explosives. So, they had no choice but to ask for help from the bureau.

Not long after the telegram for help was sent, Bureau 749 sent four more people. Two of them were professors of archaeology who had attended the meeting before, and the other two were said to be descendants of the Mojin Xiaowei and the Fachou Zhonglang Jiang from the four major tomb-robbing factions.

On the day when the four people arrived at Lange Village, good news came from the underground space, saying that the two tomb-robbing experts had found a way to open the third stone door.

…

Turn your attention back to the present.

Just as the group was about to enter the third stone gate, the chief investigator leading the team suddenly issued an order, asking everyone except the tomb raiders and the descendants of the Fa Qiu to turn around.

After everyone turned around, the two tomb-robbers walked up to the stone gate.

No one knew how they operated it, but the old Taoist priest only heard a crisp "click" sound, followed by the sound of gears turning, and then he felt an extremely cold and gloomy breath coming from behind him.

As the leader gave the order to "turn around" again, everyone turned around.

But when they saw the scene behind the third stone door, they were stunned.

When everyone turned around, a cold breath hit them in the face.

Inside the third stone door, there was extremely thick gray fog, and the gray fog seemed to be blocked inside the door by an invisible wall. Although it kept rolling, not a single bit of fog spread outside the door.

Before the stone gate opened, the two tomb-robbing masters had already left their original positions and returned to the team.

Seeing this, everyone turned on their high-intensity flashlights. The light scattered in the fog and could only barely illuminate the area a few steps away.

The director-level investigator who was in charge of the team picked up a stone from the ground and gently threw it into the thick fog.

The stone disappeared instantly after being thrown into the fog.

"This fog is a bit strange. Everyone, tie the connecting ropes tightly and don't get separated after you go in." The team leader frowned and whispered.

"Yes!" Upon hearing this, everyone immediately began to tie the connecting ropes around their waists.

“Check the air quality!”

As the leader gave the order again, two soldiers wearing gas masks and carrying instruments immediately ran over from the team at the rear.

They threw the connector connected to the air duct into the thick fog, and then turned on the instrument in their hands.

A moment later, a green light flashed on the instrument, indicating that the air in the thick fog did not contain toxic gases.

Seeing this, everyone breathed a sigh of relief.

But for some reason, when the old Taoist Xuanjue saw the fog, he suddenly had a very bad feeling in his heart.

He glanced at the little Taoist boy beside him. Seeing this, the little Taoist boy nodded slightly and immediately sent the news here to Xu Jianguo.

After receiving the message, Xu Jianguo opened the permission through the system and presented the scene seen by the little Taoist boy in his mind in real time through the system.

A similar function was used when Xu Jianguo asked Xu Yan and Xu Li to search for the geological expedition team in the cave of Peacock Lake.

Just as the scene that the little Taoist boy saw appeared in his mind, Xu Jianguo suddenly felt the burning sensation in his chest appear again.

He was slightly startled, opened his all-seeing eyes and looked down at the tattoo pattern, and found that the eyes of the great god Zhong Kui had turned scarlet, and the word "Netherworld" on the ancient seal also emitted a faint light.

After feeling this extremely cold and yin aura, the old Taoist Xuanjue immediately practiced the Taiqing Jue mental method. When the mental method was running, he felt his mind become clear and the coldness in his body gradually dissipated.

After everyone was connected to the safety rope, the team leader said, "This fog is not ordinary. Everyone, follow my steps closely and don't wander around."

After saying this, he took the lead and walked into the thick fog inside the third stone gate. Seeing this, the others hurriedly followed.

The first feeling everyone had after entering the thick fog was cold, and this cold was different from the cold in winter. It was a kind of coldness that came from the bones.

The investigators from Bureau 749 were not so bad, after all, they were not ordinary people, but the soldiers following behind them suffered.

Ever since entering the thick fog, the soldiers' bodies began to sway involuntarily.

Apart from the sound of everyone's footsteps and the chattering of teeth, there was no other sound around. In addition, the fog was so thick that one could only see a distance of two or three meters in front, behind, left and right. So after walking for a long time, everyone felt lonely.

The leader of the team was named Zhang Daochen, a Taoist priest with white hair and beard, but looking only in his fifties or sixties. He came from the Tianshi Mansion in Longhu Mountain. In fact, he and the old Taoist priest Xuanjue were of the same origin, because they were both from the Zhengyi School, and Zhang Daochen was considered orthodox, while Xuanjue was a branch.

Although he looked young, the old Taoist Xuanjue knew that this man was definitely more than fifty or sixty years old, and might even be a few years older than himself.

Since it was impossible to tell the direction in the thick fog, the middle-aged man leading the team could only move forward in the direction indicated by the compass in his hand.

He was holding a compass in his left hand and a high-intensity flashlight in his right hand. He also had two swords on his back, one of which was a peach wood sword, and the other was wrapped in coarse cloth. The old Taoist had seen it before, and it was a copper coin sword.

Knowing in advance that there was a strong magnetic field, Zhang Daochen wasn't using an ordinary compass, but one once used by their Longhu Mountain founder, Zhang Daoling. Legend has it that it contains three drops of the blood of the mythical Xiezhi (Xiezhi), a beast capable of distinguishing right from wrong, good from evil, loyalty from treachery, and even dispelling delusion and revealing the righteous path. Therefore, Zhang Daochen believed that the direction indicated by this compass would help them find the missing villagers of Langge Village.

At this moment, there was a sudden noise from the team at the rear. Zhang Daochen and a group of investigators from Bureau 749 who were walking in front immediately stopped and turned to look back.
