Looking at the snow-covered city and mountains, Xu Yi flew at a high speed in the approximate direction.

Gradually, Xu Yi found that the ice and snow were getting less and less.

In other words, the snow in the plateau areas melts faster.

Normally, the higher the altitude, the lower the temperature.

Now, it seems a bit abnormal.

With less snow, Xu Yi is more likely to identify the direction.

Enjoying the speed and passion brought by the fighter jet, Xu Yi made many difficult moves along the way.

The fighter he is driving now is a stealth fighter known as the world's number one stealth fighter, and its performance is indeed amazing.

This fighter jet is the peak complex of human technology.

Unfortunately, if such a fighter encounters a mutated bird, although it can fight, there is no way to survive in the hands of a mutated bird above level three.

If Xu Yi wants to upgrade this fighter to a fighter that can deal with level 6 and 7, he will need at least 1.5 million points.

Now, he only has more than 100,000 points, which is not enough to do these things.

However, this time Xu Yi went to Yezhou and felt that he could sign in and get a lot of things.

Yezhou was a frontier in ancient times, with many ancient tombs of generals there, as well as some Taoist practice sites and Buddhist temples.

You should be able to sign in to get some good things in those places.

Xu Yi was lucky and had never encountered any mutated birds.

Perhaps, it is because his flight altitude is high enough that there are no mutated birds moving at such a high altitude.

After more than six hours of flight, Xu Yi arrived over Yezhou.

Then, he began to search for the Red Star Space Base.

If he doesn't have a military map, it's quite difficult to find a place.

With a military map, Xu Yi can quickly find the location in the map, and then quickly compare the surrounding terrain, distance and orientation with the city, etc.

Then, find the location of the Red Star Space Base.

After searching for a few minutes, a smile appeared on Xu Yi's face.

"I found it, invisible ability, I'm here!" Xu Yi immediately adjusted his course and then flew towards the Red Star Space Base.

Half an hour later, Xu Yi began to lower the height and look for a place to land.

The Red Star Space Base has an airport, but no one guided Xu Yi.

He looked for the landing area himself.

Soon, Xu Yi locked a runway and then began to land.

His fuel was almost exhausted, so he only had one chance to land.

His technology comes from the system gift package, so it is similar to the pilots with gold helmets, and it is even more powerful.

Without any suspense, Xu Yi landed on the airport.

Then, Xu Yi drove the fighter plane to the refueling area.

First fill up the fuel, then store it in your own storage space.

This fighter jet has only 30 aircraft in the entire army, which is very precious, so Xu Yi naturally cannot park it here.

If it is destroyed by a mutant beast, it will be difficult to repair or find another one.

It took some time to refuel, and then Xu Yi put away the plane and started moving towards his target point.

Two battle knives were unsheathed and followed Xu Yi.

He held the Overlord Gun in his hand, and an air shield was condensed beside him.

At the same time, there were more than a dozen air balloons rotating around him, at a very fast speed.

If a mutant beast approaches, it will definitely be hit by the high-speed air balloons around him.

After all, there are invisible fifth-level mutant beasts, so Xu Yi has to spend some time.

He thought this set of defense was pretty good.

He was becoming more and more satisfied with the Qi-control technique.

This method may be able to achieve other superpowers, but everything condensed by the air is transparent and has a strong confusion.

Half an hour later, Xu Yi arrived at the entrance of the underground base.

Along the way, Xu Yi was not attacked, nor encountered any mutant beasts.

However, it found many traces left by mutant beasts.

By looking at their footprints, you will know that these mutant beasts are big guys and their tonnage will not be too low.

The big one is probably much bigger than the adult elephant.

Xu Yi has never fought against the fifth-level mutant beast.

He was not afraid of being beaten up in a single fight, but he was worried about being beaten up.

Xu Yi was not sure about fighting against many fifth-level mutant beasts.

Standing at a place at the entrance, Xu Yi found the place to enter the password.

Only by entering a password can you connect with people at the underground base.

All of this is designed to deal with nuclear warfare.

Even a fifth-level mutant beast wants to enter the underground base, it is very difficult.

Just as Xu Yi was about to enter his password, he felt a trace of abnormality.

"Bang!"

Just as Xu Yi was about to retreat, he heard a collision.

His air balloon broke one.

This shows that something was close to him just now.

"Invisible mutant beast!"

Xu Yi's eyes lit up and he immediately thought of the invisible mutant beast.

He directly brought the Night God helmet to see if he could see the invisible mutant beast using infrared functions.

After a quick look, Xu Yi did not see any mutant beasts.

Either it left or the infrared camera can't capture it.

"Bang."

The invisible mutant beast attacked Xu Yi again, indicating that the infrared camera was indeed invalid for it.

Therefore, the smile on Xu Yi's face became stronger.

This is not visual invisibility, but physical.

Therefore, this invisible ability is more valuable.

If an infrared camera can capture it, then this invisible ability is actually not very effective for humans.

Especially for supernatural warriors, it is relatively easy to capture, and it is probably effective for ordinary people.

But when facing ordinary people, Xu Yi can't use this kind of invisible ability at all.

Unless, he uses this ability to do bad things.

But does Xu Yi need this kind of supernatural power to do bad things?

No need at all!

In the ordinary crowd, he can really do whatever he wants. After all, his strength is there, and no ordinary person can stop him from doing bad things.

Even if an ordinary person holds a weapon like a soldier missile, it will not cause any damage to Xu Yi, nor will it stop his actions.

The invisible mutant beast attacked Xu Yi again, but it did not give up attacking him because of Xu Yi's air balloon.

Xu Yi sensed the nearby air and wanted to find the trace of the invisible mutant beast through the flow of the air.

As long as there is movement, it will definitely drive the flow of air.

Because of his qi control technique, Xu Yi is very sensitive to airflow.

In order to better sense the air flow outside, Xu Yi transformed the air shield around him.
