At this time, the Du'an Disu underground river, the blood-colored river is still unhurriedly moving along the river.

From time to time, the corpses of the fallen can be seen flowing down the river and then washed to the shore.

At this time, the demon suppressors patrolling the shore often stop, scoop up the corpses of the degenerate, and then burn them with fire.

If it is the corpse of the demon suppressor, it will be carefully salvaged and transported back to the outside of the defense circle.

The demon suppression soldiers who died in the hands of the degenerate, the three souls and seven spirits most likely dissipated together, so this body is the proof that a person once existed in the world.

The demon suppressors continued along the river until they saw the defensive circle formed by two rows of high-voltage power grids.

The blue light on the high-voltage grid is clear, and in some parts, the current even produces a plasma reaction.

Inside the power grid, some of the fallen people floated on the water, and some stood on the bank of the river, looking coldly at the artificially built high-voltage power grid.

It is precisely because of this high-voltage power grid that the 20,000 Demon Suppression soldiers can withstand more than 3 million degenerates.

Although the Fallen are like beasts and have no minds, the power of the power grid still plays a very important role.

A man in a black combat uniform and holding two rune war knives, one long and one short, was squinting into the power grid.

This person is the supreme commander of the fallen on the battlefield, the envoy of Qiannan Town, and the Yin and Yang Sword Xu Yan.

This exorcist master who took the initiative to escape from the Special Case Department for unknown reasons in the past also took on his share of responsibility again.

Don't look at Xu Yan's strength as the peak of the S-level, but because the rune sword was invented by him, it is quite popular among the demon suppressors.

It is precisely because of this that the town guards of the Sichuan-Chongqing region, the town guards of southern Yunnan, the town guards of Liangguang, and the newly appointed town guards of the Ba Fujian region all willingly obeyed his orders.

The five town guards, led by Xu Yan, took on the most difficult task of the Fallen Battlefield together.

In the absence of a super-S-level powerhouse, he can defend the underground river of Du'an Disu and firmly suppress the degenerate in the high-voltage power grid, I have to say that Xu Yan has made great contributions.

But at this time, Xu Yan looked at the degenerates behind the high-voltage power grid, and his face was unprecedentedly solemn.

Next to him, a makeshift command office was already home to all sorts of electronic devices.

The lines and data that appear on the display screen flow so fast that it makes people dizzy to look at.

Suddenly, a technician said quickly; "Lord Keeper! Detected a mass life signal in the underground river of Duandisu! ”

"The opponent is likely to launch the next wave of strikes in ten minutes."

Xu Yan said in a deep voice: "Notify the Ministry of Energy to increase the energy output of the high-voltage power grid. ”

A technician whispered, "Your Excellency, our power is no longer enough to support the high-voltage grid for the next large-scale battle. ”

The high-voltage power grid is indeed very strong, and the plasma reaction generated on it can even burn people to ashes.

But again, the energy it consumes is incredible.

On weekdays, the high-voltage power grid is hidden and does not emit, and once it is touched, it will suddenly burst out of energy.

But during the battle, the Fallen will go crazy and pounce on the high-voltage grid. If you don't increase your power, it's easy for the Fallen to tear a hole through the crowd tactics.

When the power grid fails, the unlucky ones will be the 20,000 demon soldiers stationed here!

Xu Yan waved his hand and said, "Do as I say!" If the high-voltage power grid is destroyed because of energy savings, it is really worth the loss! ”

The technician just gave advice, and when he heard Xu Yan say this, he passed down the order without hesitation.

With a humming sound, the high-voltage power grid around the entire Duandisu underground river glowed blue.

The electricity crackled, and the arc of electricity splashed on the ground, causing a scorched black.

The faces of the degenerate besieged by the high-voltage power grid showed a look of fear, even if they no longer had thoughts, but their physical instincts were still there.

Xu Yan said: "Inform the town guard envoy in the Sichuan-Chongqing region to prepare for a tough battle!" ”

"Inform the town guards in the Liangguang area that after twenty minutes, they will prepare to use river water to electrify, and ask the demon suppression soldiers under their command not to go into the water."

"Inform the town guard envoy in the Bafu region to lead the officer corps to target the strong among the degenerate."

"Tell the Sniper to be in place and kill the powerful Fallen Boss."

"Inform the two academicians to prepare a soul oscillator at any time to suppress each other's fallen black angels!"

Xu Yan's orders were passed down one after another, and there was a huge battlefield with a radius of more than ten kilometers, four town guards, more than a hundred snipers, and two academicians from the First Research Institute, all of whom received their own orders.

In an instant, the demon suppression soldiers who were still resting immediately entered a wartime state!

How big is the scale of the Fallen this time?

Tens of thousands? Or hundreds of thousands?
