Become Invincible From Void Lord

"Then, let's start cleaning up now?"

When Cui Xu said this, Cui Ying and Yun Qiang began to think.

"It's too slow to clean up like this. Sister Ying, did we open two arrow towers just now? If we choose a dangerous location and then attract those monsters in, won't the cleaning efficiency be very high?"

"Not bad! But the number of arrow towers is a bit small. And the attack power of the arrow towers is also a problem. The lowest level monster here is also a Rank Two ghoul. If it attracts faceless demons, ghost-faced snakes, or even vampire bats and werewolves, then Trouble."

Cui Xu raised his hand and pointed to the center of the Secret Realm in the distance and said: "There is a castle there. If we can occupy it, it will be cleared faster. I have no shortage of arrow towers here, and even magic defense towers, but after putting them down, It cannot be moved and it would be a waste to arrange it randomly.”

Upon hearing this, Cui Ying jumped up on a dead tree nearby, stood on the top of the tree and looked at the dark castle on the mountain, frowning.

"I'm afraid there are even more terrifying demons in that place. With our strength, we can only give away our heads if we go there!"

It is indeed too difficult for the three of them to completely clean up the Secret Realm with a radius of more than 300 kilometers.

"Then let's find a place that's easy to defend but difficult to attack, and lure the monsters over to kill them. We'll always be able to kill them all!"

Cui Xu didn't have much time, so she was unwilling to give up like this.

Cui Ying and Yun Qiang felt that Cui Xu was a little too impulsive and radical.

"Cleaning out the monsters and demons must be done step by step. For a Secret Realm as big as this, even if the powerful families want to clean it out, it will take three to five days. There are only three of us, so if we can clean it out within a month, it will be fast."

"A month? That won't work!"

Cui Xu frowned slightly, he couldn't wait even a day, let alone a month.

He reached into the storage space and began to search quickly among the cards. Soon, three special cards came into view.

[Monster attracting card: a one-time consumable, quality Rank Three, which can attract the hatred of all monsters within a radius of 100 kilometers and lasts for one hour. Please use with caution, current quantity is 3]

"What if there is such a thing?"

Cui Xu handed three monster attracting cards to Cui Ying.

"A monster attracting card? Is there such a thing?"

Not to mention Cui Ying, even Yun Qiang was a little surprised. Could these monsters be able to explode anything? Are there no restrictions?

"how?"

"It's really convenient to have this thing. But last time we came in, we encountered a group of vampire bats and werewolves. There were thousands of bat groups, and werewolves were Rank Four monsters. As for whether there are Rank Five monsters, we can't be sure. You... Once the card is used, we will be surrounded."

"When the time comes, even if we escape, we will definitely appear among the monsters next time we come in!"

"Don't worry, let's find a place to build a small camp, and then arrange arrow towers and magic towers around it, and kill as many as we come!"

Cui Xu is very confident in this, even if there is a Rank Five monster, he is sure to kill it!

"Okay, since you are confident, then do it!"

The three of them immediately set off, rushing around the Secret Realm while killing approaching monsters.

Half an hour later, the three of them found themselves at the foot of a cliff two to three hundred meters high.

"This is the best terrain nearby. It can avoid being attacked from the north. There is a dry waterway three hundred meters away, which may be used. There are woods on the left and right sides, although it is a bit sparse."

Cui Xu nodded: "Then here!"

He opened the building panel and placed five arrow towers directly on the top of the hill for air defense. Later, he felt that it was not enough, so he placed three arrow towers on each side of the mountain, for a total of eleven.

Then began to lay out the wall, enclosing a space of more than 100 square meters under the mountain wall.

The wall is nine meters high and three meters wide.

Then a total of nine arrow towers were arranged on it.

This time he left a door in the wall for entry and exit.

Then eight meters outward, another wall was built, and then an arrow tower was arranged.

In this way, Cui Xu built twelve layers of walls outwards, with hundreds of arrow towers and eight magic towers arranged on them.

In the end, he spent hundreds of thousands of Power of the Void to upgrade all arrow towers and magic towers, including walls, to Level 3.

Back and forth, it took less than an hour.

Cui Ying and Yun Qiang were simply stunned by Cui Xu's operation.

"Can you still play like this? Are all Void Lords so happy?"

At this time, both the walls and the arrow tower and the magic tower were all transformed into metallic luster and became stronger.

"How about it, does it feel safer this way?"

Cui Ying was a little speechless. She took Yun Qiang around for more than half an hour, and then said confidently: "What are you waiting for? Let's get started!"

Yun Qiang said nothing, but waved the short sword in her hand to indicate that she was ready for battle.

"Use the monster attracting card!"

Whoa, the card disappeared instantly, and a wave of light spread out.

There was no movement at first, but within three minutes, there was a vibration on the ground.

The three of them came to the outermost wall and saw densely packed monsters emerging from the east, west, and south directions.

Ghouls, faceless demons, ghost-faced snakes, and werewolves more than three meters tall.

Countless bats in the sky gathered from all directions, making one's scalp numb just by looking at them.

"There are too many monsters in this Secret Realm. Even if a big force comes in to clean them up, no matter how many manpower there is, it won't work without ten days and eight days."

Cui Xu saw Cui Ying's eagerness to try and said quickly: "Sister, now is not the time for us to take action. Let the arrow towers be consumed first. Our targets are those monsters that will cause damage to the walls and arrow towers, or are too powerful. Don’t worry about the rest for now!”

"Are you just looking at it like this?"

"Yes! How about I get you a bow and shoot two arrows?"

Cui Ying rolled her eyes at him, took the war bow handed over by Cui Xu, and really stood on the city wall and fired.

Seeing this, Yun Qiang also put away her short sword, and Bai Shengsheng's slender hand stretched out in front of Cui Xu, the purpose was self-evident.

There is no shortage of war bow Cui Xu, but there is no shortage of high-level war bows with attributes.

He handed one to Yun Qiang and started shooting with his own bow.

One more person means more strength, which can weaken the enemy as much as possible.

Monsters like ghouls can climb walls. If ignored, the first wall will be easily breached.

Faced with this situation, naturally the old method was adopted. Three people poured two barrels of gasoline each, and the fire started, which immediately burned these ghouls until they screamed.

The most important thing is that after the wall was made of steel, it was burned by fire for a long time. Even if it didn't burn red, it was still burning hot.

Even though the ghoul is a monster, he still knows pain. As soon as he got close and wanted to show off his wall-climbing skills, his claws were directly burned to half-cooked, and he let out a heart-piercing roar.

Cui Ying still felt that the fire was not big enough, so she asked for a hundred oil cards from Cui Xu. When she saw that the fire had weakened, she poured a barrel of oil down to ensure that the flames would not go out.
