Looking at the snow-covered cities and mountains, Xu Yi flew at high speed according to the general direction.
Gradually, Xu Yi found that there was less and less ice and snow.
In other words, the snow in the plateau areas melts faster.
Normally, the higher the altitude, the lower the temperature.
Now, it seems a little abnormal.
The lack of snow made it easier for Xu Yi to identify the direction.
Enjoying the speed and passion brought by the fighter plane, Xu Yi made many difficult moves along the way.
The fighter he is flying now is known as the world's number one stealth fighter, and its performance is truly amazing.
This fighter plane is a synthesis of the pinnacle of human technology.
Unfortunately, when such a fighter plane encounters mutant birds, although it can fight, there is no way to survive in the hands of mutant birds above the third level.
If Xu Yi wants to upgrade this fighter to be able to deal with sixth- and seventh-tier fighters, he will need at least 1.5 million points.
Now, he only has hundreds of thousands of points in his hand, which is not enough to do these things.
However, this time Xu Yi went to Yezhou and felt that he should be able to get a lot of things by signing in.
Yezhou was a frontier in ancient times. There were many ancient tombs of generals there, as well as some Taoist practice sites and Buddhist temples.
You should be able to sign in at those places and get some good stuff.
Xu Yi's luck is good, he has never encountered any mutated birds.
Perhaps it was because he was flying at a high enough altitude that there were no mutant birds moving at such high altitudes.
After a flight that lasted for more than six hours, Xu Yi arrived in the sky over Yezhou.
Then he started looking for the Red Star Space Base.
If he didn't have a military map, it would be quite difficult to find the place.
With the military map, Xu Yi can quickly find the location on the map, and then quickly compare it with the surrounding terrain, as well as its distance from the city, orientation and other information.
Then, find the location of the Red Star Space Base.
After searching for a few minutes, a smile appeared on Xu Yi's face.
"Found it, invisible power, here I come!" Xu Yi immediately adjusted his course, and then flew in the direction of the Red Star Space Base.
Half an hour later, Xu Yi began to lower his altitude and look for a place to land.
The Red Star Space Base has an airport, but no one gave Xu Yi guidance.
It was up to him to find the landing area.
Soon, Xu Yi locked onto a runway and began to land.
He was also running low on fuel, so he had only one chance to land.
His skills come from the system's gift pack, so his skills are similar to those of pilots with golden helmets, or even a little better.
Without any suspense, Xu Yi landed on the airport.
Then, Xu Yi drove the fighter jet to the refueling area.
Fill up the fuel first and then put it into your storage space.
There are only 30 of this fighter plane in the entire army, so it is very precious. It is naturally impossible for Xu Yi to park it here.
If it is destroyed by a mutated beast, it will be very difficult to repair it or find another one.
It took some time to refill the fuel, and then Xu Yi put the plane away and started moving towards his target point.
Two swords were unsheathed and following Xu Yi.
He held the Overlord Gun in his hand, and an air shield condensed around him.
At the same time, there were more than a dozen air balls spinning around him at very fast speeds.
If a mutated beast approaches, it will definitely be hit by the high-speed flying air balls around him.
After all, there were invisible fifth-level mutant beasts, so Xu Yi had to put some thought into it.
He thinks this set of defense is pretty good.
He was becoming more and more satisfied with the art of air control.
Other powers may be able to achieve this method, but everything condensed from the air is transparent and highly confusing.
Half an hour later, Xu Yi arrived at the entrance of the underground base.
Along the way, Xu Yi was not attacked, nor did he encounter any mutant beasts.
However, it found many traces left by mutated beasts.
Looking at their footprints, you can tell that these mutated beasts are big guys, and their tonnage is not too low.
The big one is probably much bigger than an adult elephant.
Xu Yi has never fought against a fifth-level mutated beast.
He is not afraid of being singled out, but is worried about being beaten by a group.
Xu Yi didn't have much confidence in fighting against multiple fifth-level mutated beasts.
Standing at a place near the entrance, Xu Yi found the place to enter the password.
Only by entering the password can you establish contact with the people in the underground base.
All of this is designed to deal with nuclear war.
It is very difficult for even a fifth-level mutated beast to enter the underground base.
Just when Xu Yi was about to enter the password, he felt something strange.
"boom!"
Just as Xu Yi was about to retreat, he heard a crash.
One of his air balloons shattered.
This meant that something had just come within three meters of him.
"Invisible mutant beast!"
Xu Yi's eyes lit up and he immediately thought of the invisible mutated beast.
He directly put on the Night God helmet, wanting to see if he could see the invisible mutated beast using the infrared function.
After a quick look around, Xu Yi didn't see any mutant beasts.
Either it left, or the infrared camera couldn't pick it up.
"boom."
The invisible mutant beast attacked Xu Yi again, indicating that the infrared camera was indeed ineffective against it.
Therefore, the smile on Xu Yi's face became even thicker.
This isn't visual invisibility, it's physical.
Therefore, this invisible power is even more valuable.
If the infrared camera can capture it, then this invisible power is actually not very useful to humans.
Especially for supernatural warriors, it is relatively easy to catch, and it is estimated that it will be effective on ordinary people.
But facing ordinary people, Xu Yi has no use for this invisibility power.
Unless he uses this power to do bad things.
But does Xu Yi need this kind of power to do bad things?
No need at all!
Among ordinary people, 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 such as a personal missile, it is impossible to cause any harm to Xu Yi and cannot stop his actions.
The invisible mutated beast attacked Xu Yi again, but it did not give up attacking him because of Xu Yi's air ball.
Xu Yi sensed the nearby air, trying to find traces of the invisible mutated beast through the air flow.
As long as there is movement, it will definitely drive the flow of air.
Because of his ability to control air, Xu Yi is very sensitive to air currents.
In order to better sense the airflow outside, Xu Yi modified the air shield around him.
