The Wandering Planet

The turbulent swarm of insects is still constantly impacting the energy barrier opened by the planetary engine fortress. The piled up Zerg wreckage alone has already built a height of more than ten meters in front of the barrier force field.

It is almost doubtful, if this continues, the entire Shanghai will be submerged by the sea of ​​insects together with the energy barrier. Judging by the number of insect swarms, it is completely doable. Of course, the premise is that the barrier force field can last until then.

A large number of springtails directly climbed onto the barrier force field, causing greater damage to the energy barrier by expanding the contact area.

This turned the entire Shanghai Fortress into an anthill, not only surrounded by a group of flying dragons like black clouds overwhelming the city, but also densely packed with springtails crawling around on the energy barrier, trying to get into it at any angle.

People with trypophobia will definitely be driven crazy by this scene. Even if the soldiers inside the barrier shoot outwards with their eyes closed, they can still hit the dense springtails outside, making them fall from the barrier like dumplings. fall down.

It's just that their main task is not to eliminate these seemingly endless Zerglings, but to focus their firepower on killing the Banelings mixed in a large number of Zerglings.

Different from the relatively primitive fangs and claws of Zerglings, the self-destruction of Banelings will obviously cause greater damage to the energy barrier, especially the high-strength corrosive acid produced during its self-destruction, which is far more powerful than the impact of Zerglings' claws on the barrier. greater threat.

Therefore, even if a large number of Zerglings are allowed to climb up the barrier force field, the Wandering Earth troops will not allow the Banelings to have a chance to get close to the energy barrier, and order the snipers to shoot them as accurately as possible from a distance. Once they approach, they will be killed by infantry Concentrate firepower to kill first.

Even so, a small number of Banelings managed to hit the barrier force field and detonate themselves, splashing acid onto the barrier, continuously eroding the energy barrier.

"The integrity of the barrier is 87%, and it is still being depleted!"

At this time, the charging progress of the keystone has just reached 12%, and it seems that this loss rate seems to be acceptable.

But Qiao Lv knew very well that although the number of Zergs that appeared so far was huge, they were actually cannon fodder for the Queen of Blades to try to trick the Nova Impact.

If it were the elite main force of the swarm, it would be a large group of Thunder Beasts hitting the barrier force field, and there should also be a large number of Brood Lords in the sky, as well as Leviathan, the flagship of the Queen of Blades, not just flying dragons, Zerglings and Banelings are as simple as that.

At this stage, the Wandering Earth still has to see the tricks, and wait until the main force of the Zerg lands as much as possible, and then use the Nova Impact of the Keystone to wipe them out in one fell swoop!

While the zerg outside were still continuously impacting the barrier force field,

Suddenly there was an unusual vibration from the ground, as if there was a huge beast swimming under the ground.

"Unknown earthquake movement detected, tunnel worms are coming!"

Before the words fell, a terrifying creature like a giant sandworm broke out from the ground, opened its bloody mouth and spit out countless zerg troops from it, bypassing the barrier force field from below and directly entering the Shanghai Fortress.

That is the tunnel worm of the Zerg. This giant sandworm-like creature can stretch itself to an astonishing length, thus using its own flesh and blood to form a tunnel underground, allowing the swarm to move rapidly by relying on the channel's peristalsis and chemical stimulants. The speed shuttles inside, thus posing a huge threat to the area that was thought to be safe.

The barrier force field of the planetary engine fortress can't extend to the depths of the ground, which is why the zerg spit out from the tunnel worm can directly engage with the human army hand-to-hand, which is the field they are best at.

The defenders in the city immediately bombarded the heads of the tunnel worms indiscriminately, trying every means to destroy them in the shortest possible time.

However, even so, the tunnel worms still spit out a large number of zerg troops, and started a street battle with humans in the urban area of ​​Shanghai.

And there are far more than one tunnel worm like this. If they are allowed to continue to send Zerg troops into it, the barrier force field covering the entire Shanghai will be useless!

Faced with this situation, Qiao Lv immediately ordered:

"Drilling Beast, it's time for you to dispatch!"

The prototype was obtained from the planet Cybertron, and the drill beast was used when the asteroid mined energy crystals. Now it is used again by the wandering earth as a war machine.

This dragon-like steel worm also burrowed into the ground like a tunnel worm, relying on the serrated cutterhead on its head to devour and crush soil, rocks, and anything else.

Under the ground, the Drilling Beast is like a fish in water. The Wandering Earth was able to dig so many complicated tunnels in a short period of time, thanks to this huge steel worm.

Just don't think that the Drilling Beast can only be used as a shield machine. Its body is covered with sharp serrated blades, which can not only rotate at high speed to dig tunnels, but also crush everything blocking the way like a meat grinder. thing.

The Nydus Worm stretched underground until its soft body became the best target of the Driller Beast. While it was quickly transporting the Zerg Troops in its body, it cut it in half with the high-speed rotating sawtooth cutterhead!

Unlike the Drilling Beast, which is covered in steel and steel and covered with blades, almost all the armor of the Nydus Worm is on the head. In order to be able to extend infinitely, the body has to be as soft as possible to absorb the vibrations from the ground, but The steel teeth and iron mouth of the drilling beast cannot be stopped.

The Drilling Beast easily bit off the bodies of several tunnel worms underground. Even when the tunnel worms tried to fight back through the bloody mouth, they could roll the serrated blades on their body so that they could not bite, and in turn bit the tunnels with one bite. Insect's soft body.

The existence of this terrifying steel worm made it impossible for the tunnel worms to go any further. The longer their bodies were stretched, the more likely they would be strangled underground by the drilling beasts.

Therefore, the tunnel worm can only break out of the ground immediately after bypassing the barrier force field, and would rather bear the fierce firepower on the ground than be bitten in two by the drilling beast underground.

In this way, the effect of the tunnel worms is greatly limited, and they cannot go deep into the enemy's rear for surprise attacks. They can only barely bypass the barrier force field, allowing the swarms to have a chance to enter the barrier.

It's just that even if they successfully enter the barrier force field, there are still a large number of fortifications waiting for them in the urban area of ​​Shanghai.

There are human machine gun positions on every street, and a large number of small light prism towers are densely covered like telegraph poles. The Zerg troops transported by the tunnel worms are stuck in the mud, and there is no chance to get close to Shanghai No. 1 where the keystone is placed. engine.

In this underground war, the Wandering Earth relied on the Drilling Beast to gain an advantage. The tunnel raid that the Zerg is best at has no chance to come in handy now!
