Chapter 69 Roar, Speed up, and Impact

The zombies rushed towards the machine gun tower frantically, but no matter how the zombies roared or how they bared their teeth and claws, it was of little use.

The zombies' attack power was too weak. One claw could only scratch off a little wall. Only some special zombies could effectively attack the machine gun tower.

But there were too many zombies. One or two zombies could not do anything to the machine gun tower. However, the zombies directly submerged the machine gun tower in a stacked posture under the machine gun tower, and the machine gun tower basically silenced.

Because the shooting port was blocked by the zombies' bodies.

Gradually, one machine gun tower after another fell. Although these machine gun towers were still outputting crazily, they could not cause effective damage to the zombies.

"Hey, good opportunity." When Chu Ran found this, he laughed instead of worrying.

The attack of the lightning tower is a range attack. How many zombies can be killed with this shot?

"Fire."

Chu Ran aimed at a machine gun tower that had been submerged by the zombies and fired.

The thunder ball rushed in the air, and when it reached the designated position, the thunder ball exploded.

All living creatures within a radius of 100 meters are targets of lightning attacks.

Chu Ran has upgraded the level of the lightning tower to level 10, and the attack range has doubled.

After this shot, Chu Ran saw that his level bar had increased a little.

"Isn't this to give experience?"

Chu Ran controlled the lightning tower to fire again.

There are still many machine gun towers that are submerged by the zombies. This time, Chu Ran feels that he can directly upgrade his level to level 30.

Facing the attack of the zombies, the short-term output of the lightning tower is much stronger than that of the ice-winged dragon.

The ice-winged dragon still needs to spit out its breath little by little, while the lightning tower can directly clear the 100-meter radius with one shot.

It's just that using the lightning tower is a bit expensive, 1,000 copper coins per shot.

"This, this tower is too strong, right?" The young officer couldn't help but speak.

Although he was standing on the city wall and was far away from the machine gun tower, he could not see it clearly, but he could still see it roughly.

After the thunder ball exploded, it directly covered a radius of 100 meters like a thunderstorm, and only a blind person would not be able to see it.

Even if a weaker cruise missile is used, it can only cause such damage, right?

"Not bad." Chu Ran said happily.

The lightning tower continued to fire, and with the help of the Elf Archer Corps and the machine gun tower, the speed of the zombies was greatly slowed down.

As for the Ice Wing Dragon, it was not here. He was using his breath to cut the zombies from a distance.

"Chu Ran, I want you to die." Bai Hao was very frightened. He said gloomily and hid in the zombies.

The attack of the lightning tower was too fierce. Bai Hao thought that he could not withstand a few attacks from the lightning tower.

If he was discovered by Chu Ran, he would definitely be taken care of.

Bai Hao didn't know whether he would be resurrected after death this time.

"Abandon the outer arrow towers and attack the city." Bai Hao gave an order.

Bai Hao's order was passed down step by step. The zombies that submerged the machine gun tower immediately abandoned their current targets, and all the zombies rushed to Chu Ran's main city.

"Huh?" Chu Ran frowned slightly after discovering this.

"Come on, come on."

Chu Ran looked crazy.

Even if all the zombies rushed to the city wall, what would happen?

The city was so small, it was not difficult to defend it.

"Ice Wing Dragon, come back."

Chu Ran gave an order to the Ice Wing Dragon, and the Ice Wing Dragon gave up the zombies in the distance and quickly flew back to the main city.

The Elf Archer Corps led by Shana also returned with Shana.

Under the crazy roar of the machine gun tower, the zombies rushed to the city.

"Ice Wing Dragon, defend the west, Shana defends the east, Li Guang defends the south, and don't worry about the city gate."

Chu Ran's main city only built one city gate, just to the north of what Chu Ran wanted to defend.

"Yes!"

Shana and Li Guang led the team to leave.

Ice Wing Dragon was very relaxed. It was a drizzle for the Ice Wing Dragon to defend only one city wall.

"Let's go, build a tower."

Chu Ran controlled the lightning tower to attack the zombies outside the north city while commanding the peasants to build an arrow tower.

Although a lightning tower is enough to defend the North City, it is too expensive to use only lightning towers.

Chu Ran has a way to save copper coins.

The peasants quickly built arrow towers. The construction speed was very fast. Nearly three hundred peasants built together, and a nine-level arrow tower could be fused in two minutes.

Three minutes later, Chu Ran fused a nine-level basic arrow tower in the north of the main city.

Then, Chu Ran took out the flame stone and pressed it on the basic arrow tower.

The freshly baked nine-level basic arrow tower was transformed into a flame tower.

"Over-limit upgrade."

The nine-level flame tower was forcibly upgraded to level ten by Chu Ran.

Then Chu Ran took the initiative to control the flame tower.

"Burn you to death."

The fireball condensed above the flame tower.

Then the fireball fell towards the north of the city.

The flames ran wild, and the area of ​​100 meters was instantly covered by flames.

The special smell of barbecue filled the air.

Because there was a substance to burn, the flames not only did not disappear, but were still spreading a hundred meters away.

"It works." Chu Ran grinned.

This saves a lot of money. With just a few fireballs, the north of the city instantly became as stable as an old dog, and the zombies could not get through the blockade of the flames.

"Now it's useless to have more zombies."

"Roar!"

Just when Chu Ran was secretly happy, a zombie roared.

The next moment, a zombie with an obviously strong physique appeared in Chu Ran's field of vision.

Then, the ordinary zombies blocking the special zombie immediately made way for the special zombie.

The special zombie took a running start and sped up. Under his fierce charge, the special zombie broke through the flame blockade and crashed directly into the city gate.

"That's it?" Chu Ran pouted without saying thank you.

This collision seemed to be very powerful, but the actual effect was very limited. It only knocked down 100 points of the durability of the city gate.

However, the next moment, Chu Ran was stunned.

Because this special zombie appeared again, and there were not one or two, but more than ten.

If more than ten of them hit the city gate together, the city gate might not be able to withstand a few more hits, after all, the durability of the city gate is only 10,000 points.

"It's going to be wasted."

More than a dozen special zombies roared, sped up, and hit in one go.

Chu Ran sighed and opened the flame shield of the city gate.

One element crystal per second, this speed of burning resources made Chu Ran a little annoyed.

Fortunately, Chu Ran was very satisfied with the effect.

All the special zombies that hit the city gate were ignited with raging flames.

The fire damage is one thousand per second, which is much more powerful than the flames of the Flame Tower.

The first burst of the Flame Tower is very powerful, but the damage of the subsequent flames is very limited.

If these flames are strong enough, the special zombies will not be able to break out of the flames.

But the flames on the city gate are very strong and contagious.

The zombies screamed as they were burned by the flames, and soon all the special zombies fell down.

Seeing that all the special zombies that attacked the city gate died, Bai Hao was even more upset: "Agile level 2 zombies, rush to the city wall, kill!"
