Chapter 1607 (1/2)

An hour and a half later, the first echelon of the infected group finally arrived two kilometers in front of Xifeng fortress.

From a long distance, you can see various strategic buildings in Xifeng fortress. Among them, the most prominent one is the sentry towers, which are more than 300.

These were urgently built by the slave workers in order to increase the defensive strength of Xifeng fortress as much as possible before the war.

Below the sentry tower are the army's deployed firepower guards and fire guns, as well as some detection guards.

There are more of them, with 3900 firepower guards, 2100 artillery guns and 700 surveillance guards.

These things have been opened by the road army from all levels of supply boxes for a long time. If converted into dragon coins, it is estimated that it will cost nearly one million to buy them.

The most spectacular is the huge protective device that covers the whole Xifeng fortress. It holds up a blue light that can resist all the illegal entry of enemies. The people of Xifeng fortress call it the sky curtain.

In many defensive battles of Xifeng fortress, the sky curtain was broken many times, but the road army restored it after the war.

The reason is that the sky curtain needs to rely on spar to maintain, and it needs energy to resist the attack. Once the energy is consumed, it will be broken.

If it is the previous curtain of heaven, it is estimated that it will not last long under the attack of millions of infected bodies, and the specific effect is not great.

Because the previous installation is S-level crystal, it can resist the attack below S-level at most, and the whole is relatively weak.

But this time it was different. The Lu army upgraded the curtain of heaven, that is to say, it was equipped with a crystal stone that could resist the attack of research level.

This crystal was obtained by the Lu army when they killed and destroyed the guards in the wucang area. It has been placed in the armed module. I didn't expect that it could play a role in the critical moment.

A sky curtain that can resist the attack of the research level is also the foundation of the road army to defend the infected body group. Otherwise, under the collective attack of millions of infected bodies, it is estimated that the Xifeng fortress without walls will not be able to withstand for an hour.

In addition to these defensive facilities, the slave workers urgently built a half meter high bunker in front of the sentry tower and firepower guard, mostly composed of boulders and coarse wood.

This kind of high-altitude shelter is very small, and it is impossible to block the ordinary infection body, let alone the more flexible variant infection body

However, the slave workers didn't build it to stop them. They just wanted to create a buffer.

For example, when the infected body group rushes forward, the speed is very fast, and the impact force generated is likely to directly knock down the sentry tower and firepower guard.

But with the presence of buffer belts, the infected bodies must slow down and crawl slowly, or they will be knocked down.

As long as they slow down, it will be very difficult to get up again soon. Virtually, it is equivalent to well protecting the defense facilities around Xifeng fortress.

Without the obstruction of the road army and others, the progress speed of the infected body group was obviously faster.

At the same time, the corpse controller constantly adjusts the formation of the infected body group, for example, putting nearly two million common infectious bodies at the front, acting as the first echelon.

Most of these infected organisms are d-level or even have no level. They are almost ”defective products” of evolutionary failure. The corpse controller intends to use them as cannon fodder to absorb the first wave of fire.

The second echelon is composed of hundreds of S-level tyrant infectors, nearly 50000 b-order bimodal infections and 300000 C-level elite infections.
