One Planet for Everyone! Building Science and Technology Civilization at the Beginning

Chapter 293: Showdown! A historic moment is born!

Its shape was like a big truck!

The super doubled version of the truck!

Along with the rumbling sound of the ground, it was rushing swiftly towards the wall!

Its speed was similar to that of a truck traveling at high speed.

The exterior had a layer of gray-green armor!

Clang clang clang!

Shells and bullets blasted into his armor, but it only made a sound like hitting steel!

Beyond the truck bug, the old acquainted Giant Black Bug was also upgraded again!

It changed into another giant black bug with even bigger size and higher agility!

These black bugs did not march forward on their own.

Surprisingly, it climbed on the truck giant insect and got in!

“Huh? Is this really a truck? Can it transport insects?”

Seeing this scene, Jiang Fan couldn’t help but feel a little happy.

But the faces of the Great Desolate Army were getting more and more solemn!

These truck giant bugs were faster as compared to all the big bugs before!

Its defense was even stronger!

Even if the shell hit the body, it didn’t hurt them much either!

The accuracy of the shells was a big problem!

Although it was more powerful than the speed gun, it was impossible to make several shells fall on the same location!

The most important thing right now was interfering with the truck bug and slowing down the march of these giant insects within two kilometers!

That was where the speed gun kicked in!

Tu, tu, tu……

Chang Yu Chun once again brought up twenty speed guns.

Large-caliber bullets were strafing crazily!

With so many speed guns at the same time, there would be no need to turn around.

The bullets just kept coming, directly toward the front!

On the same truck giant bug, there were dozens or hundreds of large-caliber bullets hitting in its face!

It was hitting on the same spot!

The truck giant bug was very fierce, but after traveling a few dozen meters, the first one still went down with a bang!

The giant black bugs on his body quickly crawled out.

Seeing this, the crowd breathed a small sigh of relief!

Luckily, this truck giant bug could still be dealt with a speed gun!

Rumble……

At this time, there was also a movement coming from under the ground!

New Underground Bugs were there!

Han Xin and everyone were doing defensive work, because of several underground bugs in the front.

Underground tunnels were almost full of holes. There was not a single clod of soil intact!

In the dark underground passage, a black orb suddenly scampered out!

After coming to a wider ground, this orb came to a halt.

After that, it quickly opened up and revealed the true face inside!

This was an extremely sinister-looking underground bug with long and sharp tentacles!

After seeing the crowd of the Great Desolate Army, this digger bug once again shrank its body, wrapping itself up.

It turned into a big ball again!

The grunt rolled over quickly.

It was very fast!

The speed gun was firing crazily!

Clang clang clang!

It was hitting on this orb, but it made an iron-clad sound!

Unlike the ground, the passage underground was too short!

Even the speed gun hadn’t been in play for long.

This ball type of bug had already rolled over!

“Retreat!”

Han Xin ordered immediately!

The soldiers of the Great Desolate Army hurriedly abandoned the Speed Guns and left the tunnel!

A thick gate fell down with a boom sound.

It was completely blocking the passage!

This gate was also made of alloy.

It was very difficult to break it, but it was just an opening in the tunnel.

With so many surfaces, there was always a way for bugs to get out!

The Great Desolate Army did not intend to use the gates for complete defense until the last resort!

That would be the same as sealing off the city gates, depriving themselves of the offensive initiative!

Han Xin turned his head, and a few scholars in the back looked at each other.

They all saw the thoughts in each other’s eyes!

This bug was capable of transforming into an orb and the armor of these bugs was as hard as steel.

Using a speed gun or hand-throwing bullets could no longer deal with them!

They could only use those weapons, which were known to be very dangerous!

Knock, knock, knock!

This was the sound of crypt bugs hitting the gates!

Rumble……

Immediately after that, these crypt Bugs crawled over from the other end of the tunnel!

In addition to hitting the gates, there were also some crypt bugs who chose to find a way to drill out from elsewhere!

“We can’t let them get to the ground beneath the walls!”

Han Xin knew the seriousness of the matter.

If they let these crypt bugs get too close, the Great Desolate Army on the walls would have very high pressure!

“Let’s use poison gas……”

Han Xin finally made a decision!

Poison gas!

It was a very scary weapon developed by a research team by chance!

At the time of the first test, the surrounding animals and plants basically died out!

It was way too creepy!

There were also irreversible consequences, therefore Yan personally ordered this terrible weapon to be sealed away!

Although its lethality was terrifying, it couldn’t be used on a large scale.

Naturally, it couldn’t be regarded as a conventional weapon!

It was only for specific occasions.

It could only be used against special enemies!

The perfect place for its use was underground!

Poison gas would not leak out easily!

“Notify General Chang that we will use poison gas! Get everyone ready!”

Han Xin gave consecutive orders.

Soon, Chang Yu Chun on top of the city walls got the news.

“Attention, everyone, put on your protective masks now! General Han will use the poison gas attack!”

Chang Yu Chun ordered in a deep voice!
