I met unscrupulous teammates at the beginning, watch me turn the tide

Therefore, the weapons of the fourth-level civilization are various force field weapons! And gravity bombs are one of them!

Logically speaking, once this weapon is used, the area within a radius of hundreds or even thousands of kilometers will be affected.

But this time the gravity weapon is a weakened version.

After all, there are humans around...

After Shen Bei and others evacuated to the safe area.

The Tiangong seemed to spit out a ball of black light and headed straight towards the direction where the ghost was attacking.

At the moment the gravity bomb exploded, Shen Bei sensed an indescribable gravitational fluctuation.

In the center of the explosion point, a massive star seemed to appear out of thin air. This star exerted an acceleration of at least one thousand meters per second on all the matter around it.

Immediately, the ruined buildings could not withstand the huge pulling force and began to fall towards the explosion point.

Moreover, because the gravitational force on the end of the high-rise building closer to the explosion point is different from the end farther away from the explosion point, under this gravitational difference, the hull of the high-rise building began to stretch and lengthen, and then was torn apart.

Shen Bei saw that there was also a steel bridge that was pulled into a long strip by the sudden burst of gravitational waves and quickly fell into the explosion point.

Shen Bei knew that the force that stretched the bridge into a long strip was called tidal force. Anything within the Roche limit of the explosion point would be torn apart by the tidal force.

At the same time, the ghosts that were originally flying in groups towards the Tiangong were caught by an invisible hand under the absolute gravity and dragged towards the origin gravitational field.

Wait until the gravity bomb has released all its energy.

A large circular pit over a kilometer in diameter appeared in the ruins of the entire city.

And the ghost creatures... not even a trace of them was left, they were completely annihilated.

Several scavengers stared with wide eyes, unable to imagine what was happening before their eyes.

"What...what is this?! I don't understand!"

"A spaceship? A bomb?"

"Hiss!!! This guy must be an alien, right?"

"It's horrible! One bomb, and thousands of ghosts were gone!"

"Excuse me, sir, who are you?"

……

Shen Bei didn't have time to deal with a few scavengers.

Wireless connection Lingxi Zhiling complained: "As for using gravity bombs?"

A gravity bomb, although it is a castrated version, still requires at least 300 high-level crystal source cores!

It really hurts!

Change to another weapon and grind it slowly!

You really don’t know how expensive food, oil, salt and firewood are if you don’t manage the household!

However, Lingxi Zhiling explained it.

Shen Bei understood and instantly felt that

value!

It’s money well spent!

According to Lingxi Zhiling's analysis, the ghosts here seem to have mutated.

That is, the ghost's attack is an extremely powerful pure energy attack!

Shen Bei has experienced this.

The energy attack of the mutated ghosts here has a different killing principle from that of the energy cannon.

It seems that the ghost's body contains an extremely strong negative energy. This negative energy is not the dark matter, antimatter, etc. in the usual sense, but a pure strange energy with a negative energy level, which is somewhat similar to the negative mass particles that cause the Hawking radiation phenomenon in black holes.

If the protective shield opened by Tiangong is like a cup of warm water with a temperature above zero, then these negative energies are like ice extremely close to absolute zero.

If this negative energy meets the spacecraft's protective shield, the engine inside the spacecraft that supplies the shield will immediately fall into an overloaded state because a large amount of energy has been drawn away, just like the heat of warm water is neutralized by ice.

At the same time, there will be a huge amount of radiation similar to an electromagnetic pulse sweeping through, and all the circuits inside the spacecraft may be burned out.

Therefore, for the sake of thorough consideration, the ghost is not allowed to get close to the Tiangong.

Lingxi Zhiling can only choose a dimensionality reduction attack such as a gravity bomb to solve the problem once and for all.

"All right."

Shen Bei clapped his hands: "Everyone, let's continue picking up circuit boards! Let's do it!"

Scavenger: ...
