167 Burning corpses and the camouflage net (1)

If he were to use fuel oil alone, the killing effect on the zombie monsters would be too low. Therefore, Tang Zhen also planned to add some 'seasoning' to ensure that the fire would burn for a longer time and it would be more difficult to extinguish it.

Tang Zhen had used this method to deal with corpse monsters before. Therefore, he had some experience. After walking around the market once, he had gathered most of the required materials. He placed them in a hidden corner and sent them back to the Holy Dragon City while no one was paying attention.

The last thing he needed to prepare was a large amount of fuel!

There were many gas stations in the vicinity of this city, but the amount of gas storage was unable to meet Tang Zhen's needs. After screening through the possible locations for gas storage, he finally locked his target on a large airport in this city!

The [ all-purpose electronic kit ] obtained the relevant information. Through the satellite map and building drawings, it could be seen that there was a large oil depot built on the airport, and the tall oil tank was shining in the sun.

He got into the car and went straight to his target. It didn't take long for him to arrive near the airport. A passenger plane was taking off from the airport and slowly rising into the sky.

After activating the [ quantum stealth light curtain ], Tang Zhen easily entered the airport and effortlessly found the huge storage tank. He raised his head and sized it up a few times before he began to think about how to move the fuel away.

The size of the oil tank was too large, and it was impossible to store it directly into the space. However, the fuel in bulk could not be transported, which gave Tang Zhen a headache.

Could it be that he had to bring the fire truck's tank over, fill it up, and then bring it back?

Tang Zhen, who did not have a suitable container in his hands, could only use this method in the end. However, the problem came again. How could he block the huge water tank of the fire truck and prevent others from seeing him stealing oil here?

Fortunately, there was plenty of black technology in the application store, so solving this problem was a piece of cake!

[ holographic camouflage screen. After operation, it can perfectly disguise fixed objects 100 meters x 100 meters x 100 meters, blocking a variety of detection methods. Download cost: 2000 gold coins. ]

The price was not high, but Tang Zhen was short of money. If he had not obtained some brain beads from Maronis, he would not be able to afford it!

After exchanging the brain Pearl for gold coins, Tang Zhen chose to download and install it. After the installation was completed, Tang Zhen launched the application.

According to the instructions, Tang Zhen chose the oil tank above his head as the camouflage target.

Only the user, Tang Zhen, could see that countless rays of light were connected together to form an inverted semi-circular light shield that covered all the oil tanks.

From now on, as long as Tang Zhen didn't turn off the application, no matter what he did in the net, even if he dismantled the oil tank, the outside world wouldn't notice anything unusual. They would only see the oil tank that was still standing!

Moreover, this camouflage net also had the function of blocking the sound inside, so there was no fear of the people outside finding out anything unusual after making any sound.

After solving the problem of disguise, Tang Zhen brought the two fire trucks in turn. After they were filled with fuel, they were sent back.

Then, he got a lot of containers, filled them all, and sent them back to the back of the Holy Dragon City. Only then did he turn off the [ holographic camouflage screen ] and return to the top of the wall in the other world.

The battle to defend the city continued, but the intensity had decreased a lot. As they only needed to defend against the monsters that could climb the wall, the soldiers could now take a break.

Although the 50-meter-tall city wall looked very high, it was necessary to distinguish the targets. Against the perverted zombies, the city wall of this height might not be safe. Up until now, more than ten Holy Dragon City soldiers had been hit by the flying rocks. One soldier even had his ribs broken!

These rocks were thrown up by a kind of undead monster that looked like a monkey. There were about a thousand of them, hiding behind the undead monsters as cover. The rocks were almost overwhelming. Fortunately, the city wall was high enough, and most of the rocks hit the unlucky undead monsters.

The corpse race and the corpse monsters were on two completely different levels. Facing the corpse monsters whose skulls had been smashed by the rocks, the corpse race remained indifferent!

Dodging a few rocks that were flying toward him, Tyson roared and fired at the zombie monsters with his machine gun. After The Mummy monkeys that were throwing rocks were beaten up, he laughed a few times and took a sip of water from a bottle.

Other than the stone-throwing undead monkeys, the undead archers were also shooting arrows non-stop. A height of 50 meters was already the limit of a normal arrow, but it was still within the killing range.

If it was not for the high walls and the fact that they did not dare to get close to the bottom of the walls, the dense rain of arrows would have definitely caused a lot of casualties to the Holy Dragon City soldiers on the walls!

It seemed that before these cheap zombie cannon fodders were used up, the undead army didn't intend to personally go into battle. At most, they would provide support and carry out harassment attacks.

The seemingly wooden corpse race also had their cunning!

Tang Zhen had never underestimated these guys. After carefully examining the various monsters of the undead race, he then commanded the residents on the city wall to add special 'seasoning' to the fuel!

After working for a while, the fuel in the two fire truck tanks had been processed. After the fire truck started, Tang Zhen pulled a water dragon belt and aimed it at the zombie below.

As the high-pressure water pump was running, a dark red turbid liquid splashed out. As Zhen Tang's arm moved, it was all sprayed on the heads of the corpse monsters.

The fuel that Tang Zhen had mixed was very sticky and it was very difficult to get rid of it after it stuck to the corpse monster's body. It looked greasy and the smell was also very pungent!

After the can of fuel was completely sprayed out, Tang Zhen took out a cloth soaked in fuel, lit it and threw it down.

The fireball floated down leisurely under everyone's gaze and finally hit the head of a corpse monster that was drenched in fuel. There was only a " BOOM! The area below the huge city wall immediately turned into a sea of fire. The waves of fire soared into the sky, bringing with them thick smoke!

The burning undead kept howling and struggling in the sea of fire. The fat in their bodies was ignited and turned into countless moving torches. Looking from above, the ground was full of these burning fireballs!

The stench of burning flesh mixed together, making people want to vomit. In this fiery hell, the number of standing corpse monsters decreased, but the charred remains on the ground increased!

The corpse clansmen who were hiding in the back saw that the situation wasn't good and had already dodged far away. Only the corpse clansmen with simple intelligence had already been frightened by the monstrous flames!

The fire burned for a long time before it slowly extinguished. However, the bottom of the city wall had already become charred black. There were layers of corpse monster corpses everywhere, already stuck together, and green smoke floated in spirals.

The number of zombie monsters was already quite large. In addition, the kobolds that turned into zombie monsters after dying in battle caused the number to be even more shocking. Tang Zhen's fire only burned a small portion of them.

Although it was only a small portion, it still meant that at least several thousand brains had fallen below the city wall!

However, Tang Zhen was not anxious. He had a calm and steady appearance.

As long as you dare to come close, I will set fire to you. Anyway, the brains are not afraid of being burned, and they can't run away even if they are placed under the city wall. It's not too late to go down and clean them up after the undead army is driven away!

As he watched the brainless zombie monsters approach the city wall again, Tang Zhen signaled the soldiers to start the other Water Tank Fire Truck and prepare to light another fire truck that soared into the sky!
