Three hours later, Lu Chengchuan took a car to the military base airport outside the city.

After filling up the plane's fuel tank, everyone took their equipment and flew the plane deep into the distant West.

After flying for several hours, the plane arrived at a secret military base in Xizhidi Province in the afternoon. This was not their destination, as the source of the signal was still far away.

"The source of the signal comes from a mountainous area. The exact location has not yet been found. You must be careful."

The commander of the base received them and personally told them some intelligence.

The exact location of the signal source is unclear, but it is located in a mountainous area that is desolate and uninhabited, with only wild animals surviving.

"We'll be careful. It's almost evening. We'll leave at seven tomorrow morning."

They will rest at the base tonight and take a helicopter to the source of the signal tomorrow morning.

“The conditions here are quite difficult.”

In the evening, Lu Chengchuan and others took a walk in the military area, and Qian Xiaoling couldn't help but mention it.

Xizhidi Province is a plateau area with high altitude, low temperature and thin air. The soldiers who come here have to endure many physical and mental tests.

It’s also because they have excellent physical fitness, otherwise they would be lying in the infirmary receiving oxygen now.

After walking around, everyone went back to rest.

The next morning, around six o'clock, the soldiers got up for morning exercises, and they woke up too. They went to the canteen first, had breakfast, and then went to the helicopter square.

"Hope everything goes well."

The army commander came to see them off personally and did not leave until the helicopter took off.

The helicopter flew for more than two hours and arrived at the desolate mountainous area at around nine in the morning.

The pilot skillfully took them to the location where the previous three teams had landed. After all six people landed, the helicopter turned around and returned to the military base.

It is already autumn in the desolate mountains. It is not cool in Guangnan Province at this time of year, but here in autumn, the wind is already biting.

Lu Chengchuan is not afraid of cold or heat, but it still has some impact on the other five people.

Fortunately, they were well equipped and the temperature did not affect them.

"See if you can find any traces of the first three teams. Be careful, this place might not be safe."

After landing, everyone stayed on guard for a while, and then Zhou Yaning prepared to look for the traces of the first three teams. The last missing team entered the mountainous area four days ago, and might have left some traces.

The plateau mountains are very quiet, with desolate stones and some withered weeds all around.

Not to mention other people, they couldn't even see a mouse.

Lu Chengchuan walked slowly forward with them, his mental power spreading rapidly around. In just half a minute, his mental power spread to more than ten kilometers away.

In an instant, he took in the entire scene within a radius of more than ten kilometers. In the desolate mountainous area, he only saw an animal with irregular black spots all over its body.

He took a quick look and found no useful information.

"Captain! There are footprints here!"

He didn't find any detailed clues on the ground, but Chen Long and his team did.

On the gravel ground, Chen Long and his team found a row of unclear footprints. After careful identification, they determined that the footprints were left not long ago.

"They went deep into the mountains, just ahead."

Chen Long stood up and pointed forward. Before they became psychics, they were already experts in reconnaissance, and the traces on the ground were quite conspicuous in their eyes.

"Follow me, be careful."

The traces spread forward, with Zhou Yaning leading the way and Lu Chengchuan protecting the team from behind.

At noon, the team came to a valley that led to an unknown area. This was the only way out, so they rested for a while, picked up their equipment and entered the valley.

They walked to the middle of the valley, and suddenly Lu Chengchuan smelled a special smell, like the smell of blood.

"I smell a bloody smell, right under the cliff in front." Lu Chengchuan pointed forward. The smell was coming from the front, there was no doubt about it.

"Let's go and take a look." Zhou Yaning took the lead and ran forward.

The five people ran to the foot of the cliff and soon found a pool of black blood. The blood was completely dried and stuck to the rock.

"It looks like there was an accident."

The footprints extend all the way here, so the investigation team probably encountered an accident here.

"There's no body, no lost items. Is it a monster... or a human?"

There is too little information and the specific situation is unclear, so it is difficult to determine whether it was done by a monster or humans. Judging from the situation here, it is most likely a monster.

"careful!"

Lu Chengchuan was observing his surroundings from behind, thinking that nothing would happen here, but suddenly a sense of abnormality came from the ground, and he clearly sensed that something was about to come out.

As soon as he finished speaking, something suddenly jumped up from behind Zhou Yaning and him.

Three figures emerged from the ground, and there was another figure behind him, with weapons in their hands. The figures that emerged from the ground screamed and swung their weapons at them.

Lu Chengchuan's internal energy exploded, knocking the figure behind him away. At the same time, he raised his hand and shot out several streams of internal energy, knocking the three people in front to the ground.

The four figures screamed and fell to the ground, unable to struggle.

"What are they?!"

Chen Long and his companions were shocked. These people were naked, wearing only a pair of tattered shorts. Their faces were ugly, and their bodies were dark gray, as if they were covered with dust.

They looked very human, which was also what surprised them.

How could there be people in this godforsaken place? Moreover, these people can even burrow underground. Most importantly, they are most likely the murderers who killed the investigators.

"Who knows, control them!"

Zhou Yaning used telekinesis to control the four people, and Chen Long and others went up to tie them up. The four guys were injured by Lu Chengchuan and temporarily had no strength to speak.

"Are they human?"

After tying the man up, Zhou Yaning came over to ask Lu Chengchuan.

These things looked like humans, but the aura on them was very strange, and she was a little undecided.

Lu Chengchuan's eyes turned white. In the vision of the Qi-gazing technique, the Qi in the bodies of these four people appeared black. They did not look like humans, nor did they look like those who had absorbed the divine blood stone.

"He looks human on the outside, but inside... I'm afraid he's a monster."

He didn't understand much about this, and since it was his first time seeing it, he didn't have much information.

"I'll go wake him and the others up, and you guys can interrogate them."

It’s better to ask directly than to think too much. He walked forward and sent a strand of internal energy into the bodies of these four unknown creatures.

After the internal energy entered their bodies, the four guys slowly woke up. After waking up, they immediately began to struggle, trying to break free from the restraints on their bodies.

"Who are you!"

Lu Chengchuan released a trace of his aura and suppressed the four struggling people.

Chen Long came up and questioned them in a cold and harsh tone.

The four people who were trembling with fear did not answer. Their eyes were bloodshot and their expressions were ferocious. Even though they were suppressed, they could not hide the cruelty in their eyes.

"Captain, they don't seem to be able to speak." After asking for a while, Chen Long gave up without getting an answer.
