#851 - Chapter 851: Foam Bombs Unexpectedly Show Their Power

Dongfang Chen Er hadn't anticipated that Qin Lao would resort to such unscrupulous tactics.

Therefore, he hadn't bothered to protect the Town Demon Sky Fortress.

Against the Guardian mechs, it was like a giant block of tofu, ready to be sliced and diced at will.

When the golden rune array disk struck, the Sky Fortress's 18 layers of shields didn't even react.

The array disk directly impacted the fortress's outer shell, emitting a violent roar.

The scene resembled a red-hot branding iron plunging into snow, instantly turning anything it touched into dust.

The energy contained within the array disk was also limited; a single strike could only create a large hole a dozen meters in diameter at most.

Compared to the fortress's 30-kilometer diameter, it wasn't a significant amount of damage.

But even if the damage from a single strike was relatively minor, it couldn't withstand repeated bombardments.

As the array disk struck again and again, more and more holes appeared on the Sky Fortress.

At this point, the fortress's automatic defense mechanism was activated; swarms of Hummingbird robots poured out of the Sky Fortress, launching a counterattack against the ten Guardian mechs.

"Chirp, chirp, chirp ~"

The Hummingbird robots were equipped with ion cannons. However, the ion beam attacks were ineffective, passing right through the mechs' illusory forms.

"Bang, bang, bang ~"

Seeing that their attacks were ineffective, the Hummingbird robots immediately changed tactics.

They launched the foam bombs they were carrying.

These foam bombs were originally produced to deal with the Earth's core world.

However, the fighting between the two sides later stopped, and these weapons were never used.

Each Hummingbird robot could only carry one foam bomb, but they made up for it in numbers.

The Hummingbird robots launched their foam bombs in unison, activating them.

"Boom, boom, boom ~"

The foam bombs exploded one after another, spraying liquid in all directions.

Subsequently, these liquids continuously expanded and solidified into large blocks of solid space during the spraying process.

The Guardian mechs were actually locked down for a time.

It should be noted here that the space shield can only maintain inertial motion while in effect.

Why?

Because objects outside the space bubble cannot affect the inside of the bubble, and at the same time, objects inside the bubble cannot affect the outside.

In other words, the isolation is bidirectional.

That also means that while the space shield is in effect, the mech inside the shield has no way to borrow external force to change its direction of movement.

Therefore, it can only maintain inertial motion.

So, what is inertial motion?

In a word: It is maintaining the state of motion before the space shield is activated.

If the mech is stationary before the shield is activated, then it can only be stationary after the shield is activated.

If the mech is in motion before the shield is activated, then it will continue to be in motion after the shield is activated, and it can only maintain this state of motion and cannot change it.

To change posture, the space shield must be temporarily deactivated during adjustment.

That also means that when the Guardian mech launches an attack on the outside world, it must deactivate the shield at the moment of attack. Otherwise, the attack will not be able to penetrate the shield and be transmitted to the outside world, and it will not be able to cause damage to external targets.

This is a major limitation of the space shield:

It cannot attack while defending, and it cannot defend while attacking.

When they condense the array disk and launch the array disk, they must deactivate the shield for that brief 3 to 4 seconds; otherwise, it is always on.

But regardless of whether the shield is in effect or not, after the foam bombs solidify this space, all 10 Guardian mechs are sealed in the foam.

First, mechs with shields active cannot deactivate them, because deactivating the shield requires occupying real space, and real space is already filled with foam.

Second, mechs with shields inactive can activate them, but it's useless. Because the solidified foam will also enter the space shield along with the mech.

However, mechs that have not activated their shields are better off, at least they can use brute force to break through the foam and run out.

However, mechs that have activated their shields are miserable.

They have no way to deactivate their shields, and they have no way to change their state of motion while the shield is active. They are like grasshoppers embedded in a wall, unable to borrow force, unable to move, and unable to get out. They were inexplicably fixed there, which was really full of comedy.

The powerful space shield was actually defeated by worthless foam bombs.

During the brief period that these 10 Guardian mechs were solidified, Yan Fangfang successfully drilled into the Sky Fortress through the hole.

Even Dongfang Chen Er didn't expect this result.

"I didn't expect that foam bombs would have such magical effects," Dongfang Chen Er shook his head with a wry smile.

"This is a reminder to us. In addition to tearing space, solidifying space can also affect space shields. It's just that tearing space can directly destroy the enemy, while solidifying space can only trap the enemy," Nata immediately began to think divergently.
