The four-thousand-headed snake demons were the first to rush to the main city wall to the west of the city, and they turned into nothingness under the cover of the evil blood and poisonous mist, successfully evading the monitoring vision of the Surveillance King Worm.

These snake demons divided their troops into dozens of squads, approaching the flanks of the swarm from both sides in a way that crossed the city walls.

At this time, the swarm troops around the city wall had completed their task, and the gray "purifier" fungus mist completely blocked the path of the evil blood demon soil spreading outward through the city wall.

The worm mothers who led a large army began to assemble the insect swarm under their command, preparing to move closer to the direction of the main attack at the city gate for reinforcements.

The snake men and demons hid their whereabouts and followed them, intending to find the weak point of the swarm forces at the city gate through the swarm troops who had gone to converge.

However, what these snake people and demons didn't know was that from the time they climbed out of the city wall, their every move had actually been clearly seen by the swarm.

Lilia, the master assassin of the swarm, was hidden in the void on the city wall at this time, and since the evil blood and poison cloud could affect all the contacts under the transcendental, Xue Hua did not bring it to the city with him this time.

Lilia was ordered to stay here and lead the Shadow Worm Force in the swarm to protect the swarm of toadstools.

Lilia has a true vision that can see through high invisibility and stealth, and even phasic invisibility does not want to hide its eyes, and the stealth tricks of these snake people and demons are just the simplest "mimicry" away, that is, by driving psionic energy to cover their body surface, so that their body surface can change to the same color as the surrounding environment, so as to achieve the effect of blinding vision and psionic perception.

Such a low-level stealth method could not escape Lilia's field of vision at all, and it was very easy to spot these demon squads trying to track the swarm.

Lilia quickly informed Zagara, who was directing the troops through the city gates, of this discovery through the mind of the main hive, and the mother of the hive immediately mobilized a group of spore crawlers from the rear hive.

Due to the staggered trend of the evil blood poisonous mist and the "purifier" fungus mist on the front line of the insect swarm, the observation field of the monitoring king insects in the sky was greatly affected, so it was not possible to find those snake people demon squads that were quietly approaching from both wings.

However, Spore Reptiles are ground units themselves, and they are able to view the battlefield from the perspective of ground units to avoid being obscured by clouds and fog.

In addition, spore reptiles will use the breath sensing organs that grow on their bodies to distinguish strange breaths in the air after taking root, and thus achieve the effect of detecting stealth and invisibility.

Once the spore crawlers arrived on the battlefield, Zagara quickly assigned them to the fungus blanket on the flanks of the battle line, allowing them to take root next to the path of the snake man demon squad.

Soon, all spore reptiles sent a warning message that they had detected invisible creatures, and the details of the information were transmitted to the mother worms through the main nest mind channel.

After finding out the details of the attackers, Zagala decided to stay put.

It ordered all the worm mothers to continue to return to the swarm as originally planned, so as not to show the slightest abnormality, so as not to startle the snake and let the big fish escape, and then ordered the cockroach troops to dig a tunnel to outflank the rear of the demon army by digging underground in several ways.

At the same time, all the lurkers were also instructed not to attack the enemy before the Mother Hive gave the order, and in any case, everything except for the cockroach troops underground remained as usual, pretending not to be found.

At the same time, Lilia also came to the aid with the Shadow Worm Troops, who silently followed the snake man demon squad like a flock of yellow finches in the dark, waiting for them to swallow the deadly bait.

The snake demons knew nothing about the traps set by the swarm, and they thought that they had quietly passed through the swarm's guard post and entered the core of the swarm army, not noticing that there were countless pairs of eyes quietly staring at them around them......

Soon, the shadow of a "toadstool" appeared not far ahead, and the leading snake man demon immediately waved his hand, and a team of dozens of people suddenly formed among the subordinates behind it, and quietly approached in the direction where the "toadstool" was.

The snake man demon officer, who thought that he had successfully infiltrated the hinterland of the insect swarm, did not wait for the report of his subordinates' battle results at all, and it directly continued to move forward with the rest of his men.

The same happened with several other squads of snake demons who had "sneaked in" into the flanks of the swarm, and these demons, who were naturally proficient in infiltration and sneak attacks, had always been confident in their stealth abilities.

In particular, the surrounding insect swarms looked like they were ignoring them, which made them even more confident that they had successfully invaded the enemy's core.

However, what these snake demon officers didn't know was that the teams they sent to deal with the "toadstools" had already been quietly and quickly eliminated by the shadow insects that had been following them when they were about to approach the target, and the so-called "toadstools" they saw were actually just disguised by mimic chicks......

In this way, a group of snake people and demons who did not know that they had fallen into the urn stepped into the trap carefully designed for them by the worm mothers without realizing it.

As the demons prepared to continue deeper into the center of the swarm force to find the swarm headquarters, Zagala ordered the trap to be activated.

A large swarm of jumping insects and cockroaches suddenly emerged from under the fungus blanket around the snake man demon team, and they showed their fangs and claws, and pounced on the snake people and demons without hesitation!

"What?!"

The leaders of the snake man demon squad were stunned for a moment, and then immediately understood that they had stepped into a vicious trap!

"Trap! Retreat! It's a trap! They can see us! ”

The snake man leader screamed loudly in demonic language in panic, and the snake man demon team that was surrounded by the swarm immediately became chaotic!

However, it was clearly too late to detect the swarm's intentions at this moment, and they thought they were completely caught in a ferocious siege from all sides!

"Rush out! Pull back the way you came! Fast! ”

The snake man led the army to command his subordinates to break through in demonic language, but how easy was it to break through under the siege of thousands of insect swarms?

The snake people and demons waved the long-handled steel forks in their hands in a panic, and the rear formation changed into the front formation in an attempt to break through the encirclement of the insect swarm, but due to the huge number gap and the chaos of the sudden siege, their plan was not smooth from the beginning.

Jumping insects attacked them one by one, and cockroaches destroyed and tore at the snakemen's hard-fought formation from underground and from afar.

Lacking backup and besieged, the snake demons quickly found themselves in a predicament, which quickly turned into a desperate situation when the swarm's ranged strike units joined the siege.
