The last sound of the Wild Armor indicates that there is an emergency, and the brood is required to immediately send a wave of insects to attack the area.

Receiving the information sent by his most cherished warrior with his life, the mother worm did not hesitate to spread the pheromones that enveloped the entire nest, and more than 100,000 adults all received the will of the mother worm, and they were immediately filled with incomparable killing intent, and set out of the nest and headed towards the cave area.

They were extremely fast, some flapping their wings, others crawling on the ground, converging into a huge black torrent that seemed to devour everything in their path.

Blade Fire dragged his body that had exceeded the limit to his feet, and weakly warned everyone in the channel:

The insect tide is coming.

There are still more than twenty minutes left before the upgrade is completed, and everyone doesn't know if they will be able to complete the upgrade before the insect tide arrives.

The two warrior monks ran from the direction of the Black Sword, carrying the blade fire and Shang Zhengyu, who were no longer able to walk, and ran back.

"Chuxin, how long will it take for the insect tide to arrive?" Shang Zhengyu asked.

In the upgrade of the Black Sword, all unmanned fighters cannot be used, and Xia Chuxin can only play the role of command and support.

"The first wave will arrive in ten minutes."

"Let's move on to the second stage." Shang Zhengyu said.

The first stage is to use passive defense and assassination to ensure that the Turbid Blood Zerg or other threats are not alarmed, so as to avoid a situation that seriously threatens the safety of the Black Sword such as insect tides.

The second phase, where the presence of the Black Sword has been exposed, seriously threatens the upcoming defensive phase. At this time, there is no need to continue hiding, and all forces should be used to protect the Black Sword that is being upgraded in the depths of the cave at all costs.

In the first phase, all active units are stealthy, such as Priests and Blood Sacrifices, to ensure that defenses are organized and not detected.

There was no need to hide in the second stage, and all the defensive firepower and troops that Chen You had built up before this poured out and were ready to fight.

Outside the cave, the six electromagnetic machine batteries that were originally hidden in the bushes and distributed in a fan-shaped shape were activated, and the remnants of the squad were identified, and the machine guns fired in unison, instantly annihilating the soldier and insect squad.

Four Ming King giant mechas, fifteen Shura heavy mechas, and twenty-five warrior monk mechas, all arrayed at the mouth of the cave, the cave is scattered and stacked with all kinds of ammunition, piled up into several hills, more than 50 light and heavy weapons are all facing the outside of the cave, waiting for the arrival of the enemy......

Countdown to the completion of the Black Sword upgrade: 20 minutes.

Although he was in the medical cabin, Shang Zhengyu's eyes were still fixed on the situation at the entrance of the cave in his field of vision.

As the minutes ticked by, he waited anxiously......

Suddenly, through the broadcast of his vision, he saw an out-of-phase at the far end of the jungle.

At night, as if it were a real tide, a black current rushed far away.

The shrubs and trees of the jungle in the distance were all swallowed up by this black tide and ceased to exist.

Hundreds of thousands of pairs of insects can already be heard, as well as the thirsty and hoarse chirping of insects.

The insect tide is faster than expected, and the front of the black tide expands at an alarming rate, allowing them to make frantic sprints regardless of their physical limits.

The mechs in the front row could already see the outlines of the soldiers in the front row, wielding the giant scythe on their forearms, driven by the simple killing intent, and rushing wildly.

Even if it was just a broadcast of the field of vision, the boundless insect tide still made Shang Zhengyu feel deeply uneasy.

Both the mech and the defensive turrets are set to fire freely, and after the AI calculates that the front of the insect tide is already in the range of fire.

The eight mortars with the longest range and the four electromagnetic cannons held by the Ming King opened fire.

There is no need to think about the problem of hit rate at all, because there are too many enemy troops, and concealment is not considered at all, so as long as you shoot in that direction, you can hit!

The mortar shells fell in the air like meteors in the insect tide, bursting into small explosions, flying six or seven soldiers and insects, and their bodies were shattered by the explosion.

The electromagnetic cannon shell pierced directly into the formation, penetrated the soldiers and insects in the front row, and then exploded inside the insect tide, which also caused a lot of damage.

The lethal effect of explosive weapons is amazing, but it's still like firing at the tide – it can stir up waves, but it can't stop the tide from rushing forward!

The six electromagnetic machine batteries distributed at the mouth of the cave and the machine guns in the hands of the Ming King opened fire, whether it was the rate of fire or the caliber of the bullet, these ten machine guns were the insecticidal trump cards.

Ten bright yellow lines of fire intertwined and pierced into the insect tide, and dozens or hundreds of soldiers and insects were immediately damaged by devastating penetration.

The combination of explosive weapons and cannons seems to have slightly curbed the speed of the insect tide's advance. The soldiers and insects in the front row were constantly killed, and the corpses were all over the place, hindering the advance, and the black tide slowed down as if it were overflowing the high ground.

The corpses at the front of the insect tide piled up higher and higher, and the soldiers and insects who arrived in the back row had to climb the hill composed of the corpses of their own clan, and continued to use their bodies as the shields of the soldiers and insects in the rear, advancing forward in this unbelievable and extremely terrifying way.

The effect of the cannons was indeed obvious, but after their firing focus hit the middle, the front of the insect tide, which was slowed down by the corpses, began to expand to both sides, forming two wings, making the front edge of the tide twice as wide!

The soldiers and insects came around from the side, and the long line of soldiers was pulled, which obviously diluted the concentrated fire effect of the cannons, and the formation of the insect tide became wider and continued to advance.

Countdown to completion of the Black Sword upgrade: 16 minutes.

The insect tide approached with difficulty in the fierce steel rain of machine guns, and finally arrived at the position where the team had arrived before, Shura and the warrior monks scattered around the machine fort and the Ming King, and the heavy machine guns in their hands also fired, and the triple firepower was the limit of the defensive firepower at the mouth of the cave, although it could not fight back the frenzy, but it still curbed the pace of the soldiers and insects.

The machine turret has a comprehensive heat dissipation and ammunition supply system, which can continue to fire almost non-stop, but the cannon and cannon equipped by the Ming King still need to replace the ammunition, even with the cooperation of the warrior monk, there is still a weak period of firepower, and the insect tide will take advantage of the time to replace the ammunition, or wait for the weapon to cool down, and advance forward little by little.

Some of the soldiers were very cunning, and since the bodies of their companions were already piled up like walls, they hid behind the walls, waited until the fire was a little quieter, and then followed the group to charge. Little by little, little by little, the front of the insect tide began to approach the cave......

Countdown to the completion of the Black Sword upgrade: 13 minutes.

Finally, the endless soldiers and insects rushed to less than ten meters of the defensive formation, and the soldiers and insects that were like giant beetles roared and rushed forward, as if they were about to touch the edge of the defensive formation.

Ten meters is already the range of damage that can be ensured by the giant scythe throwing, and the soldiers and insects with the perfect development of the giant sickle, from the ground or the air, threw their giant scythes, whistling and flying into the machine formation, and there are constantly warrior monks or Shura who are hit by the thrown giant scythes and scrapped, and the machine fort and the Ming King have also been damaged to a certain extent.

At this time, nearly 90% of the ammunition piled up at the mouth of the cave had been used, and the mountains of ammunition were all turned into hot shells and spread on the ground, almost reaching the ankles of the warrior monks.

According to the calculations of the built-in computer of the soldiers, they have already annihilated nearly 7,000 soldiers.

However, this is still only a drop in the bucket for 100,000 insects.
