The people around them originally hoped that this potion bomb would be of some use, but now this situation has left them a little at a loss and don't know what to do.

Wan Lin looked at the black clouds that were slowly approaching this side, and his face was very ugly.

The flight speed of those mutated insects is not very fast, but it is not slow, according to the speed, it can be estimated that it only takes 40 minutes to fly from that area to the outskirts of Colorful City.

That is, they only have 40 minutes to prepare.

At present, the range of arrows is still relatively long, and many insects can be shot in black clouds without stopping.

But the corpses of those mutant insects will be eaten by the living mutant insects around them in an instant.

The arrows in the Colorful City are not ordinary arrows, although they are made of wood, but this wood is not the wood that can be found in the city.

The wood had some strange powers, and the mutated insects had no interest in these arrows, and just gnawed at the corpses of their kind.

Wan Lin looked at the situation of those arrows, his eyes lit up, they were all thinking about unconventional means before, but they didn't expect that the conventional weapons produced by the system could actually cause damage to these mutant insects.

The point is that these mutated insects did not take an interest in these weapons, and in this way, the lethality of the weapons appeared.

The people around saw that the look on Wan Lin's face had calmed down, and their mood involuntarily slowly calmed down.

They saw that Wan Lin was still staring at the black clouds, and they were also staring at the black clouds one by one, and began to discuss other plans.

Although Wan Lin seemed to be looking at those mutated insects on the surface, he was actually looking at the system interface in front of him.

He looked for weapons in the mall that could deal with the mutated insects.

Since the system's weapons can deal with these mutated insects, the laser cannon will certainly be able to deal with these mutated insects as well.

But if you only rely on these laser cannons, you will definitely not be able to eliminate so many mutated insects, not to mention, the insect cloud formed by these mutated insects is overwhelming.

These small-scale weapons are definitely not good, they must be weapons for large-scale attacks.

Wan Lin looked in the mall and took a fancy to a few weapons of large-scale destruction, but he wasn't sure if it would be useful to those mutant insects, so he used a function that he used to use often, search!

"System, search for lethal weapons against mutated insects."

The system chime soon sounds.

Wan Lin looked at the two weapons that appeared in the mall.

Wall of Fire: 200M*200M, a continuously burning defensive weapon. Price: 100 Radiance!

Flame Cannon: Fires a Flame Shell in 10 seconds, with a radius of 100M. Price: 100 Radiance!

Wan Lin looked at these two weapons, his eyes flickered, his current brilliance value has broken through the 100,000 mark under the accumulation of these few days, and it should be enough for these two weapons.

These two weapons may be of great use in one attack and one in defense.

Wan Lin has now put all his hopes on the system, after all, there are so many mutant insects, if they kill them all by themselves, I don't know how many people will die.

Wan Lin quickly said to Xiaoxian and Yun Rou, "You two come with me!" ”

Xiaoxian and Yun Rou's eyes lit up, could it be that Wan Lin wanted to have any good weapons again?

They all knew in their hearts that Wanlin had a secret, a secret that could make the Colorful City appear.

But they all knew very well that a person who could easily come up with an unusual weapon would do well not to probe his secrets.

Especially since their lives are in Wan Lin's thoughts.

Because they saw so many magical weapons, they would unswervingly believe that their lives were really mastered by Wan Lin.

Wan Lin took Xiaoxian and Yun Rou to a hidden place in the corner of the wall and took out two space bags from their bodies.

One was handed to Xiaoxian and one was handed to Yun Rou.

"Xiaoxian, the device inside is placed every 20 meters, and then 3 layers are placed outside the city wall."

"Yun Rou, this is a flame cannon, you distribute it, and let a few squads surround those black clouds separately and attack directly. Infinite Cannonballs! ”

Xiaoxian and Yun Rou quickly took the space package given by Wan Lin, and immediately greeted the captain of the Lin team in charge of their respective responsibilities and began to issue tasks.

It's not that Wan Lin doesn't believe in the captain of the Lin team, but he doesn't want his secret to be known by too many people.

Xiaoxian and Yunrou have been classified by Wan Lin as the housekeepers in the system, and on the premise of believing in the system, Wan Lin still believes in these two people.

Of course, if the system can't believe it, Wan Lin feels that he won't be able to live long in this apocalypse.

He didn't want to rely on the system, but in this situation, it wouldn't work if he didn't.

Even the transfer circle is provided by the system, and if there is really a situation where the system abandons him, it will be a betrayal of relatives.

However, Wan Lin has asked about this before, and in the system's answer, this world will only be bound to Wan Lin.

This gave Wanlin a little peace of mind about the over-reliance on the system.

After arranging the tasks of Xiaoxian and Yunrou, Wan Lin returned to the city wall, and his mood was slightly lighter as he watched Xiaoxian lead a team of people to install the installation of the fire wall.

Because of the size and scope of the black cloud, Wan Lin gave Xiaoxian about 100 devices.

Each device is 200 meters, which is a range of 20,000 meters.

On average, there are 3 barriers, about the same, each of which is about 6,000 meters away.

This location of Xiaoxian is actually very well furnished.

A row was installed in the center of the black cloud and the city wall, which was 8 kilometers long, completely covering the front of the colorful city.

Then, two more rows were placed in two more rows in front of each of them.

In this way, the three layers are repeated and the length is guaranteed.

After Xiaoxian led people to quickly install the device, Wan Lin called him with his wisdom brain and asked him to assist Yun Rou, and then turned on the equipment of the wall of fire.

Bursts of flames erupted from those devices in an instant, forming walls of red fire.

Except for the area of Wanlin, the rest of the city wall was full of people, and some of them exclaimed as they looked at the wall of fire standing in front of the black clouds.

The whole row of fire walls, the burning flames seem to be close in front of you, and you can feel the scorching flames.

You can see the temperature of the flames above the fire wall.

As soon as the wall of fire came out, the sky seemed to be dyed red, and even the black clouds that had obscured a lot of light reflected a lot of red light.

And at this moment, in different places around the black cloud, a loud sound sounded at the same time, "Boom, boom! ”

The burning red balls rushed into the black clouds like meteors, and then exploded violently, and the flames instantly swept through the space that exploded.
