168 Chapter 166! harvest, unstoppable

The flames soared into the sky several times, the air near the city wall was extremely dirty, and the ground was piled with a layer of black ash. When he picked it up and rubbed it with his fingers, it felt greasy.

This terrifying method finally intimidated the undead, making them not dare to approach the area within five hundred meters of the city wall. They could only surround the city from a distance, trying to cut off the Holy Dragon city's access and trap the Holy Dragon City to death.

When they were dealing with Black Rock City, they had used the same method, and the results were obvious!

Now, they were using the same old trick to deal with the Holy Dragon City, but they were destined to go for wool and come home shorn. Tang Zhen was still hoping that these people would stay in their original places obediently and help him farm monsters and accumulate brain matter!

After filling the two fire truck tanks with fuel, Tang Zhen stopped moving, leaving only one empty tank. If it wasn't for the lack of containers, Tang Zhen would have emptied all these tanks and carefully stored them.

With weapons like tanks and fire trucks, the Holy Dragon City would not have to worry about zombie attacks for a short period of time!

Glancing at the growling corpse monsters, Tang Zhen ordered people to prepare a large number of ropes. He called over a dozen Holy Dragon City cultivators and let them fall down from the city wall.

Some corpse monsters tried to rush forward, but they were torn into pieces by the bullets before they could run a few steps. After killing nearly a hundred of them, the corpse monsters controlled by the corpse clan became obedient. Other than moving around anxiously, they did not take another step forward!

Tang Zhen simply ignored these low level corpse monsters. With his current rank 5 cultivation, he could completely kill his way in and out of the group of corpse monsters. He did not even need to rely on his strength.

When one's cultivation reached a certain level, one's strength would undergo a qualitative change. Currently, Tang Zhen could already feel a trace of it. It was as if the strength in his body was undergoing a subtle change. It was just that it was not obvious.

Tang Zhen needed to sacrifice the brain beads. Therefore, he went through the trouble to come down and collect them. Otherwise, he would only need to come down alone and order his phone to directly absorb them. It was simple and saved time.

Unfortunately, the application store only had the option of exchanging brain beads for gold coins, but not the function of extracting brain beads.

Enduring the strange burnt smell, everyone began to search for the brains among the charred remains. With the keen senses of cultivators, they could easily find the brains among the remains.

Compared to the other cultivators who had their backs bent and heads lowered, Tang Zhen was much more relaxed. He discovered that his perception ability was getting stronger and stronger. He could easily sense any brain Pearl within a ten meter radius.

Tang Zhen controlled his storage space and quickly collected the buried brains. His work efficiency was equivalent to the sum of everyone else's. Every time he walked through a designated area, a pile of brains would appear in his storage space.

The brain beads collected were of different levels, with most of them being level two. It was clear that after a period of evolution, these corpse monsters, which were mostly Wanderers, had all leveled up once!

Seeing that Tang Zhen was leisurely picking out the brains and was getting closer and closer to his position, a corpse race Centurion who was in charge of controlling the corpse monsters roared and pounced towards Tang Zhen.

When the corpse race's Centurion was less than five meters away from Tang Zhen, it had already raised its huge bronze battle blade in an attempt to split Tang Zhen in half!

Tang Zhen, who was removing the brain, didn't even raise his head. Instead, he turned his body to the side and kicked the stone on the ground. A piercing sound suddenly rang out, followed by a blood-curdling scream from the corpse race Centurion. Half of his neck had been smashed by the stone.

The corpse race's Centurion was dressed in heavy armor. This was a part of his body that was rarely exposed, but when he faced Tang Zhen, it became a fatal weakness!

The corpse race's Centurion, who had half of his neck broken, was extremely tenacious. He still staggered and pounced forward, trying to kill Tang Zhen. However, he was sent flying by Tang Zhen's kick and fell heavily on the ground, unable to get up again.

Compared to the corpse monsters that were purely transformed from infection, these corpse race members were actually a bit weaker. Tang Zhen did not use much strength and killed this level four corpse race Centurion!

Seeing that Tang Zhen had killed a level 4 monster so easily, the soldiers on the city wall began to cheer in unison. This sound also stimulated the undead race. They immediately roared and drove the undead monsters to pounce on the crowd.

"You guys go back, I'll Cover You!"

Tang Zhen took out his large alloy sword. After he easily brandished it, he spoke to the people behind him in a deep voice.

The Black Mass of corpse monsters rushed over. Tang Zhen roared and rushed forward. The alloy sword in his hand was waved by him, creating countless afterimages. It was like a red iron rod that fell into the snow. The ice and snow immediately melted wherever it passed.

Flesh and blood flew in the air, and blood splattered everywhere. It was unknown how many zombies were chopped into pieces by the alloy sword, but anyone who was within a three-meter radius of Tang Zhen was not able to escape the fate of being beheaded!

The power of a Grade 5 cultivator was this terrifying!

Tang Zhen was in the midst of killing when he suddenly felt countless rocks falling from the sky. He turned his head to take a look, only to discover that there was a group of mummified monkeys squatting on the ground. They were emitting mournful roars as they continuously threw rocks at him.

There were too many rocks and they continuously fell around him. Tang Zhen was extremely annoyed and anger rose in his heart. He took out a grenade and threw it towards the group of mummified monkeys.

The grenade exploded, scaring the group of mummified monkeys into jumping all over the place. However, they still persevered in throwing rocks at Tang Zhen!

He took out his machine gun and fired. After driving these mummified monkeys far away, Tang Zhen laughed at himself. He thought to himself,"why am I angry with a group of mummified monkeys?"

After slashing another level-four zombie with the body of a giant crocodile and the head of a giant python, Tang Zhen took out the brain Pearl and began to retreat in the direction of the city wall. The zombie monsters stopped chasing after them when they reached the border of the burning area. They only roared at Tang Zhen continuously!

Tang Zhen let out a sigh of relief. He had just fought and exhausted a lot of his strength, but his battle results were outstanding. The corpses of the corpse monsters on the ground were powerful proof.

Tang Zhen sat on the body of a level four corpse monster. He rested for a while before getting up to collect the brain beads again.

After being busy for half a day and cleaning up the battlefield, Tang Zhen followed the rope and returned to the city wall. He began to count the gains this time.

A large pile of brains was scattered on the ground. Tang Zhen led Qian Long and Tai Seng as they squatted on the ground and divided the brains into small piles according to their ranks. It didn't take long for them to finish counting.

This time, he had obtained more than 5000 Level 1 brains, more than 14000 Level 2 brains, less than 1000 Level 3 brains, and only a few dozen Level 4 brains!

No matter what, he had gained a lot this time. At the very least, he had gathered enough brain beads to upgrade the building. One must know that in order to gather enough brain pearls to upgrade the tower, Tang Zhen had racked his brains and had even shamelessly extorted Black Rock City.

Now that he had enough brain beads, it was time to prepare for the upgrade of the building.

Due to the lack of brain pearls, Tang Zhen originally planned to wait until the flashing gold race's sanctuary was completely cleared before considering the problem of upgrading the tower. However, it seemed that there was no need for this now!
