This attack was smoother than the previous two.

Relying on the cover of the three-story back door panel, the siege army successfully arrived under the city wall.

When the suspension bridge on the siege tower was put down, the direct shots of the divine arm bow on the top of the city were all blocked by five layers of thick wooden shields.

Seeing that the five thick wooden shields were indeed worthy of expectations, Abbas immediately sounded the horn of the attack.

As the sound of the horn sounded, the orc warriors holding five-story wooden shields on the siege tower immediately rushed up the top of the city along the suspension bridge.

Seeing that the divine arm bow was ineffective, the orc warriors on the siege tower raised their shields and rushed towards the city. The divine arm archers facing the suspension bridge immediately dodged to the side.

When the divine armed saboteers flashed and left, a big guy with a yo-yo was immediately exposed.

It was a dark iron box, with a huge long and thick iron pillar behind the box.

One end of the iron pillar reached into the box, and the other end was hung in a huge slot.

As an orc warrior pulled a handle hard, the slot immediately sank, and then the iron pillar that was originally stuck in the slot immediately bounced forward like an arrow from the string.

The moment the iron pillar bounced forward, the baffle in front of the iron box also moved forward rapidly.

It turns out that the other end of the iron column is connected to a huge iron plate, and at the middle end of the iron column there are two snaps, and there is a huge spring device behind the snaps.

Originally, when the iron column was stuck in the trough, the spring inside the trough was compressed. As the trough was sunken, the spring inside the trough immediately began to stretch. Then, under the action of huge elastic force, the iron column connected to the iron plate at the top was quickly bounced forward.

The iron box was facing the enemy to carry the suspension bridge on the top of the city, so the orc warriors who had just stepped on the suspension bridge to rush to the top of the city were immediately bounced out by the iron plate stretched to the top of the suspension bridge.

Under the huge elastic force, the orc warrior on the suspension bridge suddenly fell over and over.

The appearance of this scene shocked the orc warriors on the siege tower.

Looking at the huge iron plate that was beginning to shrink toward rebirth, many orc warriors were all confused.

"Don't stand stupidly and continue to attack.

It takes a long time to load that elastic device at once, so you can hurry up and kill me during this vacuum period.”

Those Aboriginal Orc warriors did not understand that this was the most basic spring principle, but Abbas, as a player, saw through the principle of this thing at a glance.

Although it is difficult to make such an installation in the game, it is still very easy to see through its working principle.

As an engineering student, Abbas just saw the iron column inlaid with iron plates and stretched for a while, and he immediately knew what it was and what its function was.
