7 Chapter 7 Upgrade the Drone

It wasn't long before Jack stood at the door, the heavy metal door opened automatically.

"Welcome to the scientific research center, Master."

"Congratulate to unlock the scientific research center. The system sent out a novice gift pack."

"Novice gift pack: 2000survival points, a p95 pistol that can cause fatal damage to zombies, thirty special pistol ammunition."

"Note: All the products produced by the scientific research center are special weapons that can cause damage to zombies."

Not long ago, Jack received a novice gift pack. He was stunned.

His survival points had recovered from a pitiful 600 to 2600.

The rest of the rewards needed him to enter the scientific research center to receive.

Jack's eyes lit up as he entered the scientific research center.

The facilities in the room were not as luxurious as he thought. There were only a few simple and different desks.

They were created to build different weapons. Though it looked simple, it was a high technology!

Jack approached the desk where small weapons were produced.

Normally, the special p95 pistol and the special bullets would be produced there directly.

Sure enough, two white laser beams were lit up on the desk.

After the two beams of light dimmed, a hand-shaped object gradually appeared on the metal plate of the table.

Jack knew that it was his special p95 pistol!

Needless to say, the guns Jack had prepared before must not cause much harm to the mutants.

Now that he had a special weapon in the castle, he could fight against those monsters.

Another two minutes passed.

As expected, two items were placed on the metal plate of the desk.

A special version of p95 with silver luster and two special clips matched with it.

There were fifteen bullets in each of the two clips. Jack could tell that they were extraordinary.

These bullets looked like polished silver, but Jack had no idea of their real material.

Even the greatest scientist in America might have been unable to analyze the materials of these bullets.

Jack held the special p95 pistol in his hand, feeling very comfortable.

The special pistol was as light as a feather, and the metal surface was warm, without any coldness.

If the pistol wasn't made by the powerful system, Jack would have thought that it was a plastic toy pistol that could be bought for ten dollars in a toy shop.

Similarly, the bullets that matched the pistol were also very light.

Jack carefully put the clip into the pistol, played with it for a while, and put it in his pocket.

The special p95 didn't work much for him now. He couldn't go out to face the mutants and the Bumblebees before he had any combat experience.

What he needed was a fighter drone!

But this kind of thing was extremely precious to their country!

Although the situation was not good now.

But Jack knew that it was because the armed special forces sent by the country all carried the old weapons of the last century.

Hummer fighters, steel armored tanks, and so on were all the products left behind from the last century.

The real arms were still hidden.

Jack was disgusted with this kind of behavior. Now he just wanted to create a powerful weapon to hunt.

After studying it for a while, Jack knew what to do next.

He put his hand on the desk, and the system information came soon.

"Current level of the scientific research center: Lv. 1"

"Unlocked weapons: p95 pistol, m16 rifle, Fighter drone, Regular bullets."

"Next level will unlock: Ferocious revolver, m24 rifle, armor-piercing bullets."

Jack chose to upgrade it to a fighter drone.

"Do you want to upgrade it to a fighter drone? You need to pay 800 survival points."

System asked him.

"Yes."

Jack said straightforwardly.

This time, there was no work on the stage, and there was nothing new on it.

For this kind of large weapon, the system would directly produce or upgrade and place it in the place where it should be placed.

Only a drone was far from enough. Jack had to fill the machine with enough useful weapons and ammunition.

After the drone upgrade came out, the system provided a series of evolution directions.

"Upgrade direction:

First: Nuclear missiles, which have strong destructive power, and are easy to cause a range of great damage. It consumes 1500 survival points."

"Second: Explosive armor-piercing Gatlin machine gun. Its attacking speed is very fast, and it has a strong single killing ability, which consumes 1000 survival points."

Undoubtedly, two kinds of weapons could give a powerful fighting weapon to a drone.

Of course, in addition to these two powerful weapons, the drone itself also had its ordinary weapons, but unfortunately, its power was not great.

But Jack had spent a lot of points to upgrade the drone, and he was only 1600 points left.

The points were just enough for Jack to install nuclear missiles into the drone.

"I choose the first one."

Jack chose the first one without hesitation.

What was expensive was good, which was the only rule for him to believe.

After getting this powerful weapon, a new hint came from the system.

"Hint: At the doomsday, every time you kill a mutant, you can get points according to the creature's strength."

Jack's eyes lit up when he heard this.

Now Jack couldn't wait to send it out.

It could not only help the people but also earn points.

It was killing two birds with one stone.

A few minutes later, Jack heard a loud crash from the basement.

Loud bangs came one after another, just like drumbeats.

It meant that more than one monster was attacking Jack's fortress.

Jack hadn't taken the initiative to attack those mutated monsters, but he didn't expect that they would come to him!

Although the sound was very loud, it did not cause any damage to Jack's special space metal wall.

Jack thought without hesitation.

Now was the best time to kill them.

The prey came to the door and he couldn't waste it!
