After carefully inspecting the surroundings, Wei Yi found a few slight marks under the cobbled together cars. He made a closer look, and thought it looked like the tracks of several cars coming out one after the other.

But these traces are not very obvious, if it weren't for Wei Mi's careful look, and his eyesight was originally much stronger than ordinary people, if it weren't for this, I'm afraid it would be difficult for Wei Mi to find these traces.

Wei Yi leaned over the ground and looked at it carefully, he felt as if most of these marks had been deliberately erased. But the person who processed the traces obviously didn't spend too much time on it, so there were still some very shallow traces that remained. It was these traces that made Wei Yi realize that the person he was looking for had already left this place.

Wei Yi squinted, took a closer look, followed the faint traces on the ground, and followed all the way. He wanted to know, how the hell did those people leave? There was a kind of close surveillance on the ground, and it was clear that the people had not left the ground.

But if they hadn't left the ground, would they have been able to travel from under the ground all the way away? Although the underground facilities here are very large, there is an end to them. Wei Yi followed the intermittent traces on the ground. On the way, there are traces of artificially erased from time to time. This also greatly affected the progress of Wei Yi's tracking.

However, Wei Yi's eyesight is extraordinary. Although those faint traces were not easy to catch with the naked eye, they were still found by Wei Yi one by one. He eliminated all traces of human interference, followed the traces of the car left on the ground, and quickly followed all the way until he reached a wall before stopping.

When the marks on the ground arrived, they were cut off by the wall. Wei Yi tracked it down here, and he had to stop. After carefully examining the marks under the wall, he concluded that the wall was a wall that could be raised and lowered. Or maybe the wall itself is a giant metal door.

"There should be a console around." Wei Yu muttered to himself.

He quickly searched around. A console that controls such a large wall will certainly not be too far away. Following this line of thought, Wei Yi quickly searched around for a while, and soon found the console.

The method of opening is the same as before. Wei Yi used the key card on his body to swipe it on the console, and the wall slowly rose. As the walls gradually rose, a glimmer of light shone in from the world outside the walls.

This is the light on the ground. Wei Yi was overjoyed, hurriedly left the console, and quickly ran towards the rising wall. The slowly rising wall, after rising, completely revealed the world outside the wall in front of Wei Yi's eyes.

Beyond the walls is a long dirt road that weaves through several ridges. There are clear wheel marks on the ground of this dirt road. Obviously, when it comes to this, those who have left do not have much time and patience to do the work of erasing the traces.

The wind whistling all around was fierce and wild here. The air was filled with dust, almost obscuring it. Such an environment made it difficult for Wei Yi to open his eyes and look into the distance.

Wei Yi covered his eyes with his hands, quickly walked out of the underground facility, leaned over the ground and carefully checked the traces on the ground, then quickly got up and ran back. The tire marks left on the dirt road have not been completely melted away by the strong wind, so it can be seen that the group will not be away for long. If Wei Yi can't follow it quickly at this time, after a long time, I'm afraid he will really lose the trace of the other party completely.

Wei Yi wanted this and immediately ran back. He ran to the commander, asked for a car, and quickly left the place, tracking in the direction of the enemy's flight.

The winding mountain dirt roads are not very easy to follow. The potholes that appear on the ground from time to time also greatly affect Wei Yi's driving speed. Moreover, because it was a tracking operation, Wei Yi had to get out of the car from time to time to check the traces on the ground to identify the direction in which the other party was going. After determining the correct direction of the other party's departure, Wei Yi could continue to track. It's an extremely hard and tedious task.

Wei Yi followed all the way and left the realm of the Brotherhood branch. He stopped as he walked, checked and tracked, and drove far away. But tracing the tracks is not always easy. The variable is a number that is difficult to control. For various reasons, Wei Yi also lost the exact trace of the enemy shortly after leaving the territory of the Brotherhood Branch.

And the reason for this result is that the other party unexpectedly drove the car into the river. All traces of the enemy, when they arrived here, were completely cut off. Wei Yi traced all the way to the river, and saw that the tire tracks not far from him disappeared into the river, but there was nothing he could do.

He could only sigh as he watched the slowly flowing river. In the tracking operation, the most troublesome thing is to encounter those enemies who have anti-tracking capabilities. Such an enemy would cause endless trouble for trackers like Wei Yi.

Now it seems that there must be such people in the other team. Wei Yi shook his head and smiled, and said secretly: "Unexpectedly, there are some smart people among you. ”

That kind of enemy, who knows how to hide his whereabouts and knows how to evade the enemy's tracking, is the most troublesome and tricky opponent for Wei Yi. For such an opponent, Wei Yi really doesn't have any particularly good ways to deal with it.

"Now, we can only take one step at a time. Let's hope there are one or two pig teammates among them, or else this trip might be wasted again. Wei Yi muttered to himself.

He quickly exited the car and took a closer look at the flow of the river. It is a large river that flows from east to west. Wei Yi tried to go into the water and test the depth. The depth of the river was just above his waist. At this height, unless the other party is driving at a fast speed, any kind of car will stop due to water ingress.

In order to know the specific situation of the other party's driving, Wei Yi calmed down and carefully observed the situation in the riverbed. He hopes to determine the direction of the other party's traffic by looking at the riverbed. In this case, he may be able to continue to find the whereabouts of the other party.

Through the clear water, Wei Yi can clearly see the situation at the bottom of the river. The cobblestones at the bottom of the river walked in a haphazard manner, but there was no sign of any speeding cars. Wei Yi leaned over and touched the pebbles on the riverbed. The pebbles are arranged in a chaotic but flat manner. It doesn't look like there's a car moving at a speed.

And Wei Yi also found a very strange phenomenon, that is, there is no living creature growing in this river. This is a very abnormal situation.

There are no aquatic plants, no small fish, no crabs, snails and other creatures that are common in the river. Wei Yi looked at the lush trees growing around him, and couldn't help but be a little puzzled.

Along the way, Wei Yi found that the enemy's favorite places to go were these places where lush trees grew. He followed all the way down, and he didn't know how many of these woods he had passed. In the same way, many rivers have been passed.

But every river is very different from this one. Those rivers are home to all sorts of creatures. Unlike this one, it's so clean and clear that it's confusing.

Wei Yi slowly walked along the riverside and observed. As he waded across the river to the other side, he gradually discovered something even stranger. On the other side of the river, there was no sign of a car passing by.

No, not the slightest trace.

"No," Wei Yu said to himself, "If the car gets into the water, then how can they drive?" Unless they're driving a boat. They did not drive along the river, nor did they cross the river to the opposite side. Could it be that they burrowed into the ground? ”

The more Wei Yi thought about this question, the more he felt that something was wrong. He quickly walked back to where the trail had broken off and looked at it carefully. The last trace left on the ground was straight towards the river. Through this trace, Wei Yi also found the enemy's car, and even left two deep tire marks at the place where it entered the river. But then there was nothing. It's as if it disappeared into thin air.

The pebbles around that trace were merely a little messy, and they didn't leave any useful clues. "How is that possible?" Wei Yi muttered. This situation made him feel more and more that the other party might have gotten under the ground.

He quickly took off his coat and trousers, stepped barefoot into the water, and groped around where the last traces were gone. One pebble after another was pushed away from that place by Wei Yi. The mud and sand that rose up stained the river around Wei Yi to a mess.

Wei Yi searched for several hours before he gained something. He touched something very hard under the riverbed. Judging from the touch on his hands, Wei Yi felt that it was like a kind of metal. He stopped in a hurry, and groped around the place.

The hard object on the riverbed, under Wei Yi's groping, gradually revealed its shape. It appeared to be a semi-oval metal gate. When Wei Yi discovered this place, he quickly cleaned up all the pebbles and mud around the gate.

After doing all this, Wei Yu quickly went ashore and drove the car to this place. He stood on the roof of the car, looking down carefully.

When the river became clearer, the gate was fully revealed. It was indeed a semi-oval metal gate. Through the clear water of the river, Wei Yi could clearly see that a huge vine pattern was also carved on the gate.

"I can't believe so." The corners of Wei Yi's mouth curled slightly, and he moved his hands and feet, and walked towards the gate again. This time, he needs to find out how to open this place.

The key card in Wei Yi's hand, he didn't dare to use it easily in such a place. What if it gets into the water? What if there is water ingress and some internal wiring is short-circuited? Wei Yi has such a magical card on his body, if the road behind him needs to be opened with this thing again, but he makes it short because of this, it will be really bad.

With that in mind, he left the key card in the car and stood barefoot next to the gate.
