The data on the life detector is gone.

"How is this possible, the detector just now showed that there are at least tens of thousands of people active there. Cao Gui couldn't believe this fact.

In just over an hour, the data on the life detector disappeared without warning, and what made people feel even more strange was that the data on the detector showed no signs of movement.

"Did they disappear out of thin air?"

The detector in Wang Si's hand could detect any vital sign within a radius of hundreds of miles.

Previously, the detector showed that within a radius of hundreds of miles, only this one place showed signs of vital activity, and in just over an hour, those vital signs disappeared cleanly.

"Could it be that there is a problem with the detector?" Chen Chunan guessed.

"Impossible, this is the most advanced life detector in my Datang Kingdom, there are runes engraved by saints on it, even if there are saints in the other camp, it is not necessarily that they can interfere with this detector in my hand. ”

Li Ba was very confident, the runes in the detector in his hand were engraved by an old saint of the Tang Kingdom.

It was an old antique that had been sanctified for a long time, and it was a mythical existence in the entire Tang Empire.

"If it weren't for the problem with the detector, what would happen to tens of thousands of people disappearing out of thin air?" Chen Chunan felt incomprehensible.

No one can explain this.

Call!

Suddenly, a strong wind rose and the wind and sand filled the sky.

The icy and piercing breath came from behind Zhang Ruochen and the others, and the cold air made Chen Chunan can't help but think of the black crack again.

"Could it be the black crack that swallowed them?"

Chen Chunan guessed in his heart, this guess startled him, it was tens of thousands of people, and everyone was at least a monk above the Qi Realm, and there were many powerful and terrifying powerhouses among them.

If they were really swallowed by the Black Rift, it would at least show that the Steppe Tribal Alliance was not united with the Underworld.

"By the way, do you think there is a problem with this desert?" asked Chen Chunan.

"Nonsense, so many things have happened along the way, even a fool can see that something is wrong with this desert. Cao Gui's tone was rude, and he responded to Chen Chunan unceremoniously.

"Brother Chen, do you have anything to say?" Zhang Ruochen looked at Chen Chunan and said.

As the oldest elder in the Pioneer Brigade, Zhang Ruochen had a strong insight, and he could see through Chen Chunan's implication at a glance.

Chen Chunan hesitated for a long time, and then he spoke: "Do you remember the black crack I mentioned to you?"

"Say whatever you want. "Cao Gui is a straight person, and he can't see what others have to say, so let Chen Chunan directly say what he wants to say.

Chen Chunan said: "The black substance and the green-haired monster are all from the underground world in the black crack, since the green-haired monster and the black substance appear here, and the surrounding air is still so cold, there must be a black crack here that connects to the underground world." ”

Chen Chunan said a lot in one breath, he paused for a moment, and then continued: "The black crack can not only release underground creatures, but also devour all living beings. ”

Wang Si and Zhang Ruochen fell into deep thought.

At the moment, there is no more plausible explanation in their minds other than this one.

After pondering for a long time, Zhang Ruochen asked, "How can you prove that they were swallowed by the black cracks?"

Chen Chunan shook his head, all this was just his guess.

"Since you can't prove it, don't speculate. Cao Gui's eyes were wide open, his hideous face was majestic, and his voice was even more irresistibly majestic than Wang Si.

Cao Gui looks like five big and three thick, but he is not just a person with developed limbs and a simple mind.

The sentence just now was not deliberately aimed at Chen Chunan, but because Chen Chunan's words would have a bad impact on the psychology of the soldiers of the Pioneer Brigade, and he was using his own methods to weaken the morale of other soldiers who were beginning to waver.

Chen Chunan stopped talking, and the eyes of all the soldiers fell on Wang Si, and they were all waiting for Wang Si to give another order.

Wang Si's slightly vicissitudes of life were expressionless, and he was pondering.

Ever since they left the Shence Army camp, what had happened along the way was beyond their comprehension.

Wang Si was very difficult, and his next decision was related to the life and death of the entire Pioneer Brigade.

If they continue their mission and go elsewhere to search for the large camp of the Steppe Tribal Alliance, they will inevitably take a great risk.

Even if there were no black cracks here, just one green-haired monster would wipe out their entire army.

But if he didn't continue to carry out the mission, he had already set up a military order in front of the general, and it was a soldier's duty to obey the order, let alone a military order.

This is related to the honor of a soldier and the image of the brigade commander, as well as the honor of the entire pioneer brigade.

"The search for the location of the enemy's large camp continues. ”

Wang Si hesitated for a few minutes, he finally made a choice, the honor of the soldier, and overcame the fear in his heart.

The function of the life detector is not only to detect vital signs within hundreds of miles of the surrounding area, but also to realize the function of map indexing.

After opening the map on the monitor, Chen Chunan raised his eyebrows, and his heart was suddenly shocked.

The place where tens of thousands of vital signs disappeared was originally a flat sandy area, but Zhang Ruochen said that it has now become a ravine, and it also exudes an extremely cold atmosphere.

Chen Chunan looked at the watch in his hand, which showed that it was ten o'clock in the evening.

Wang Si and Zhang Ruochen quickly determined a route, and the vanguard brigade set up camp again in the cold wind.

Chen Chunan's heart always had deep worries, and he really wanted to exchange views with Huang Ying.

This little guy has a mysterious origin, special abilities, and can feel unknown dangers, and he wants to ask Huang Ying if there is any danger around.

However, when fighting against Wu Lei, Huang Ying consumed a huge amount of money in order to help Chen Chunan avoid Wu Lei's pursuit, and once again fell into a short sleep.

He tried several times to call out to the Yellow Warbler, but failed to wake him up.

Chen Chunan could only follow the men and horses of the Pioneer Brigade on the road with a nervous and uneasy mood.

In this case, if he left the ranks of the vanguard brigade alone, it would be purely an act of seeking death.

So, even if he was reluctant, he had no other choice.

Every time he walked a distance, Chen Chunan looked at his watch from time to time.

"Why has it only been ten minutes?"

Chen Chunan was very puzzled, with his judgment of the speed of travel, he felt that he had traveled hundreds of miles, but only ten minutes had passed.

Although the monks of the Swallowing Yuan Realm were very fast in their speed, they were a team of more than 100 people after all, and their speed would at least be affected to a certain extent.

When they walked a hundred miles again, Chen Chunan looked at his watch again.

"Another ten minutes?"
