Needless to say, the sealed barrel is so intact. Even if it is the tattered bear domestic products, Qin Guan doesn't have to worry. Under the scouring of time and space energy, the barrel will become intact again.

Now, exchange, start!

Qin Guan confidently started the exchange, but the familiar energy fluctuations did not appear. Qin Guan looked at the interface that the system popped up for him in surprise.

Can only be exchanged as a whole?

In the previous exchanges, Qin Guan encountered such a problem. When he exchanged tanks, he was divided into three batches because of lack of mental energy. They were exchanged sequentially. However, when exchanging planes, However, it is not allowed to be disassembled. It has to be exchanged as a whole. If the exchange is so easy, this big guy, the spirit of the overall exchange, is at the same level as the aircraft carrier!

Facing this scene, Qin Guan wanted to cry without tears.

He intends to sell this cannon to the date palm country, in order to test whether this cannon still has a certain practical value in the war, instead of going to the date palm country, if the date palm country cannot receive the new cannon, This is a cannon that is incomplete and will explode as soon as it is fired. Isn't that the country of date palms?

Stop trading now? He is the omnipotent President Qin. There is nothing that he can't do. It is like this now, and there must be a solution!

If they can’t be exchanged separately, then Lao Tzu will disassemble the naval gun and become a separate entity. There is always no problem, right? Standing on the dock outside the battleship, Qin Guan thought to himself in front of the cannon.

If you take it apart, you don’t have any tools at hand. Moreover, the current system has been upgraded. The time outside and inside are flowing at the same rate. In this case, you can take apart the battleship’s turret by yourself. The war outside is over!

How to do it?

Just as Qin Guan was using his brain, a person slowly walked over, that beautiful woman, who had not changed at all after several years.

"Lisa, you are too interesting, go out alone without taking everyone!" Looking at the person who walked in, the Hero of the Prairie was very annoyed. Everyone was inside, and you went out alone. A firmer program has been set up so that no one can get out.

"This is a coincidence. Don't be envious of this kind of luck." Lisa said, "I'm here to help Qin Guan complete the exchange."

"How to help?" Qin Guan also turned his head at this time and looked at Lisa.

"It's very simple." Lisa said: "We can exchange twice."

Two exchanges? Qin Guan looked at Lisa. After each other could control each other's body, Qin Guan felt that he knew more about Lisa, but Qin Guan still didn't know what Lisa meant now.

"First use the ordinary and cannons and other quality things here to exchange, for example, the tower crane on the dock over there, it's almost the same? Exchange the cannon, and then exchange the cannon back!" Lisa said.

Come in first, go out again, what's the picture?

The picture shows the repair function of the system!

The cannon cannot fire because the internal barrel is damaged. Then, let it walk through the system. When it goes out again, the cannon will naturally be able to be washed by the space-time energy of the system. It's as good as ever.

When Lisa said this, Qin Guan suddenly understood: "Yes, the system can be used in this way, but we must be fast."

It must be fast. Right now, the cannons are still advancing outside. If someone in the convoy finds that the cannon on their gun cart has suddenly turned into a tower crane, how surprised!

Must be fast!

"Of course, I am here to help you modify the program of the system so that this exchange can proceed quickly." Lisa said.

"Woo, the system is going to be broken by you." At this moment, a voice appeared in the sky, and the system was aggrieved. Then, a little loli appeared from the sky.

The exchange of roles in the system makes Qin Guan very uncomfortable. Moreover, there is a big ambiguity in this sentence. How did I break you up?

"How long has it been, haven't upgraded, just want to play with me, no, others don't want it."

"The exchange begins." Qin Guan felt that if he went down, he should be crazy. This little loli actually came and hugged her thighs. The bigger the others, the longer and smaller you are. If you become Mature woman, she can accept it, but she is a little loli. If you continue to develop, will you become a baby?

Start!

At this time, the exchange was very easy. There were ripples in time and space in the sky, and then the ripples continued to develop and became a big hole. In this big hole in time and space, the 406 mm cannon flew in, and the tower crane was facing the opposite. Direction, flew out.

At this moment, on the missile launcher, Xiao Lu, who had not made much noise, flew out all at once, transformed into a long sword, flying in the sky, she blinked her eyes, feeling It's incredible, what's going on? Can the cannon become a shelf? The shelf is so long and it sticks out a lot, and the driver will find out. What is President Qin doing?

Just after she took a look, the shelf disappeared and turned into a cannon again. However, compared to the previous cannon, it has changed a lot. The surface looks more full of metal texture. Inside the cannon, the rifling is bright. , There was no small crack in the whole barrel.

The system has been successfully refurbished after this exchange!

President Qin always has so many weird things. Forget it, let's go back. It seems that it is only a short-term behavior. The cannon is the cannon.

Am I dazzled? At this moment, the driver of this car asked himself very strangely. He was driving well just now, but suddenly he felt a flower in front of him. Then, in front of his car, there seemed to be a long shelf, and the shelf was still there. It swayed before my eyes, and suddenly disappeared.

Well, it must be dizzy. I didn't sleep well last night. Today I received an order to drive the car to a nearby base. It seems that I am not as good as young people when I am older!

The driver attributed this phenomenon to his dazzling, and to other people who saw it, they also felt it was dazzled. They didn't know that Qin Guan had already used his system to create a new function. The system was renovated. Dafa!

A powerful system was actually used to recycle waste products. Little Lori was very upset. After completing this operation, Qin Guan retired.

The cannon has been repaired, and now there is one last thing left, and that is, to quickly transport this super big guy away.

In what way? Of course it is a ground-effect aircraft still under development!
