As the Zerg army left the insect nest, the entire mutant tribe began to get busy quickly. Under Ides' command, all the mutants had already divided into several parts according to their combat effectiveness and attack characteristics and remained in their posts to deal with the Zerg that could arrive at any time. At the same time, Yasai also took out the portable base defense system obtained from the federal government.

Although it is called a portable base defense system, these automated machinery are actually not small in size. The first thing that was taken out was a defensive turret called the Fire Spitfire Round Tower. The Fire Spitfire Round Tower was specially developed by the federal government to deal with Zerg cannon fodder teams such as velocity insects. Although the tower body of this defense turret is only four meters high, the round turret can spray a high-temperature torrent with a wide coverage. In the face of this deadly torrent, even the velocity insect will be instantly burned like thin paper in front of the flames and turned into flying ashes. Moreover, the part of the Fire Spitfire Round Tower is equipped with three high-temperature incendiary bombs, which can cause terrifying collective damage to large-scale enemies at medium and long distances.

This time, Yayan brought a total of twenty fire-breathing round towers from the federal government and placed them on the four city walls of the tribe. With the help of these fire-breathing round towers, no matter how many velocity insects came, the enemy would not be able to climb up the city wall before the energy of the fire-breathing round tower was exhausted.

However, if you rely on the Fire Spitting Round Tower alone, the base will not be able to be defended anyway, because although the Fire Spitting Round Tower is very lethal, it is no longer of great use for some creatures of fifth-level and fifth-level or above. So once the city wall is destroyed by those high-level Zergs, these Fire Spitting Round Towers will only be transformed into a pile of fragments. However, the federal government will certainly not ignore these high-level Zergs, so in addition to the Fire Spitting Round Tower, the feeling also brings another automatic defense weapon specifically for dealing with the High-level Zergs - the base butcher.

The base butcher is one of the most powerful energy weapons in the Federation. This weapon device looks a bit like a thick gossip base. A metal gun barrel is erected in the center of the base, which is one meter in diameter and looks amazing. The sub-barrels extending outward from the top of the main gun barrel are only 20 centimeters in diameter. However, the main gun barrel shooting will consume a large amount of energy from the base butcher, so in general, the base butcher uses the sub-barrel to kill enemies. After all, the penetration power of his sub-barrel energy weapons is enough to penetrate the biological armor of the fifth-level Zerg.

The war for more than ten years caused the federal government to suffer a lot from the Zerg, so they also established a three-line defense system on the ground, underground and sky. In addition to dealing with the fire-breathing round towers of the Zerg on the ground and the base butchers of the high-level Zerg, the federal government also brought the pulse generator and anti-aircraft turrets, two weapons and devices to deal with the underground Zerg and the high-altitude Zerg.

The pulse generator is the smallest weapon device brought by Yayan this time. Their appearance is somewhat similar to a round football, but a long metal rod is connected to one end. Once these pulse generators are inserted into the ground, the metal rod will emit continuous pulse ultrasound. This ultrasound is not harmful to nearby creatures, but it will cause vibration and resonance under the ground, causing huge damage to underground creatures and pushing them out of the ground.

The federal government's air defense turret is very similar to the human air defense turret in "Starcraft". The rectangular muzzle is filled with tracking incendiary bombs as big as a finger. This incendiary bomb can automatically track high-altitude enemies and ignite them. Although its power is not enough to kill those flying Zergs, the high temperature is enough to burn the flying Zerg's insect wings and make them lose their flying ability.

Fire Spitfire Round Tower, Base Butcher, Pulse Generator and Air Defense Turret, these four automatic war weapons provide powerful defense capabilities for the mutant villages. However, after all, it is just a portable base defense system. Once there are too many Zergs, this defense system is still very likely to be destroyed by Zergs. Therefore, while these automatic weapons exert their power, the mutant on the city wall must fight bravely to reduce pressure for these devices, so that the defense system of the entire base will be more solid.

After installing the portable mechanical defense system, Yagan and Zhou Feng no longer care about the affairs in the village, but gathered together to continuously improve their plans to deal with the crypt lord. This war is extremely dangerous, especially Zhou Feng, who needs to deal with the crypt lord with Ides and open up the emotional realm. With the wisdom of the crypt lord, he may have the full effort to break his realm first. In this way, Zhou Feng's danger is even above Ides.

However, Zhou Feng still has several life-saving cards. The first is the iron ring of insect lice. The endless insect lice can block the crypt lord for him for a period of time. The second is the teleportation function of the Earthly Walk Boots. Three short-distance teleportation ability is equivalent to three chances of life-saving for him. What's more, he has the Spring of Life that can greatly increase the recovery speed of his body, so even if he is injured by the crypt lord, he may not die. As for the rebirth and strengthening effect attached to the angel tears is enough to allow him to have the combat power to fight with the crypt lord in a short period of time.

Of course, Angel Tears are rare treasures. Even if Zhou Feng defeats the crypt lord by using Angel Tears, the result of his battle will probably be more than worth it. Therefore, before the battle, they must discuss every detail and strive to get the greatest gain at the lowest price. What's more, there is a stronger Zerg leader in the surface world. If even dealing with a mere sixth-level crypt lord would make Zhou Feng consume the angel tears, then he would be afraid that he would have to die in the final battle.

"You actually let those mercenaries run away?"

Just as the Zerg army was advancing towards the base where Zhou Feng and others were located, the crypt lord was also communicating consciousness with Hartrum, but soon he exclaimed in his mind.

"Anubarak, are you accusing me?"

Hearing the exclamation of the crypt lord, Hartrum immediately roared in a low voice.

"No, no, no, I was just surprised, because in theory, you either don't take action, but once you take action, you should be able to complete the task, right? Isn't this the reason why the clan leader sent you as the commander this time?"

Hartrum's roar made the crypt lord immediately lower the voice in the sea of ​​consciousness. He was really surprised, because with his understanding of Hartrum, this guy should be able to kill those human mercenaries without any suspense. But now, Hartrum not only did not catch those human mercenaries, but even failed to kill any of them... This is really incredible.

"These human mercenaries are not simple. They not only react quickly, but also have extremely skilled combat cooperation. Even if I sent forty humans and bombs to launch suicide attacks on them this time, they were blocked by one of them. Moreover, the brainworms in these puppet bodies have just hatched, and their control over the body is very average, which leads to their slow action. Otherwise, these people would have been dead long ago."

He snorted impatiently, and Hartlum continued: "I'm looking for you this time to remind you that these humans had exchanged a batch of portable defense systems before leaving, and according to what they said in their words, their target is probably you. Be careful and don't be careless!"

Although he always calls Anubarak a bastard, a bastard, and is full of hostility towards Anubarak. After all, both Hatrum and Anubarak are blood flowing from the same family, so Hatrum specifically reminds Anubarak.

After saying this, Hatrum directly cut off communication. After hearing Hartrum's words, Anubarak couldn't help but condense in his heart. He knew very well how powerful human technology in this world is. Even if he was hit by a micro-nuke, he would probably be either dead or injured. Fortunately, the special architecture of the underground world determines that it is impossible to use any powerful explosive weapons. But even if those powerful explosive weapons cannot be used, some of the human weapons and equipment can still hurt him, so he must act carefully.

Thinking of this, Anubarak suddenly ordered to a worm beside him: "Tell me the order, the troops will accelerate, and we must completely destroy these humans before they are ready."

"Yes, Master!"

Hearing Anubarak's words, the insect next to him immediately passed his orders. Then the entire Zerg's march suddenly became at least 30%, and they rushed towards the direction where Zhou Feng and others were at an extremely fast speed.
