Above the gray fog

"Welcome the envoy of the upper tribe to our grass spirit tribe."

An old grass spirit with a yellow body came forward. The grass spirit tribe can judge their age by the color of their bodies. The skin of this grass spirit is yellow with a dead black color. It can be seen at a glance that he is already in his twilight years.

There are also some young grass spirits in these sequence 8s. Their skin is emerald green and smooth. They should be teenagers or young people among the grass spirits.

"We are here to install anti-aircraft guns for you. You can see where to install it." Liu Heng said.

"Is this a pet of the upper tribe? Or a branch tribe member of the upper tribe?" The old grass spirit looked at Lin Shan and asked.

This big-faced monster is the same as the head of the upper tribe except for its big face.

"No." Liu Heng had no choice but to reply on behalf of Lin Shan, "We just had an accident, which is why it became like this."

"So that's how it is." The old grass spirit nodded, and then asked, "Can you give us a more detailed introduction to the weapons brought by the upper tribe?"

The team that went to the human race at the beginning only heard the verbal introduction of the Sequence 8 weapons, and they forgot everything after returning. The only thing they knew was that the weapons were very powerful, enough to threaten Sequence 8, and that one Sequence 8 potion was needed to exchange for ten.

As for other materials, they were nothing to them. The resources of the entire tribe had never been mined, and the resources were naturally ridiculously abundant in such a large area of ​​the tribe.

"Of course." Liu Heng nodded.

Then he said slowly:

"The second test 135mm pure spirit penetrating anti-aircraft gun - the muzzle is 11 meters long, the ground range: 11,600 meters, the air range, 11,000 meters, using the fast-changing loading mode, can fire 10 pure spirit penetrating shells in 15 seconds. This kind of shell has no fancy effects, only extremely strong penetrating characteristics."

"Excuse me...what is a meter? Is it used to measure distance? How far is 11,600 meters? Can it be changed to 'zhang' or 'li'?" the old grass spirit continued to ask.

In their civilization, there is no unit of meter.

Liu Heng showed a surprised look on his face, but still explained for the old grass spirit, "The ground range is about 23 li, and the air range is about 22 li."

The old grass spirit was very satisfied with the distance. It was thinking about where to install it to achieve the greatest effect.

Liu Heng translated the old grass spirit's words to Lin Shan.

Lin Shan was also a little surprised that the Grass Spirits didn't have the concept of rice. He remembered that the Cats had this concept.

Perhaps it was because they were the natives of the Gray Mist World.

"Excuse me, can this anti-aircraft... gun stop the attack of a Sequence 8?" The old Grass Spirit asked after a moment.

Liu Heng didn't know about this question either, so he had to ask the researchers next to him.

After the researchers answered, Liu Heng wrote it down and then passed it on.

Unexpectedly, before Liu Heng spoke, a dark green Grass Spirit next to the old Grass Spirit took the lead in translating:

"With sufficient ammunition, each anti-aircraft gun has the ability to force back Sequence 8. As long as it is hit, Sequence 8 will also be injured. It is easiest to knock down the body, but if you want to kill Sequence 8, it is only possible if ten anti-aircraft guns are aimed at one target. After all, Sequence 8 is too mobile."

The old Grass Spirit nodded. He was quite satisfied with this situation. Each one had the ability to force back Sequence 8, which was equivalent to having ten more Sequence 8 transcendents. The disadvantage was that it could not move, but as long as it was well protected, it could still play a big role.

The most important thing is that the upper tribe also promised that if it was damaged by an attack, it would be repaired for free as long as the core was still there.

This was equivalent to adding ten permanent extraordinary people to the front line, exchanging one sequence 8 potion for ten sequence 8 defensive power.

They exchanged twenty machines, which was equivalent to doubling the defense of the front line.

This deal was worth it in their eyes. If there were only two potions left, they would have wanted to exchange for more.

"Follow me, sir. I will take you to the place where you need to install it."

Everyone followed the old grass elf.

Along the way, the originally bumpy ground was now covered with plant huts. These were all woven by the grass elf warriors guarding the front line. Their military discipline was very loose. When the enemy came, they would pick up their weapons and fight. When the enemy left, they would weave a hut and sleep on the ground.

Sequence 9 was responsible for blocking the attack of the other side's sequence 9, and sequence 8 would not interfere. The sequence 8 of both tribes had already set rules. No one wanted the enemy's sequence 8 to rush into their own sequence 9 camp and slaughter them wantonly.

As for whether adding anti-aircraft guns will break their rules, it is highly unlikely. Anti-aircraft guns only target Sequence 8 masters, and they will not use anti-aircraft guns to bombard Sequence 9's battle zone.

Doing so will not only cause the Twilight Clan to counterattack, but will also accidentally injure friendly forces.

"I don't know how this anti-aircraft gun works. Sequence 8 is very mobile. Are you sure you can hit it?" The old grass spirit asked again.

"There are two operating modes. One is remote control with spiritual silk threads, which requires very precise control of spirituality. The other way is manual control, which is more convenient and has a faster loading speed, but it is vulnerable to attack."

"We will leave someone behind to teach you how to use it and simple maintenance."

"As for whether it can hit..." Liu Heng smiled confidently and said, "Is your flying fish very fast? The flying speed of the shells is about twice that of your flying fish, reaching 750 meters per second. If the direction is not known in advance, it is difficult for Sequence Eight to dodge."

"More than one mile per second, this speed has reached the level of sequence 7. How did they do it..." Hearing Liu Heng's words, the old grass spirit was shocked.

Liu Heng smiled but did not speak. Only by superimposing dozens of layers of spiritual repulsion can the acceleration of a shell reach this level. The repulsion ritual has been optimized and updated by the human race for decades.

The reason why bullets and shells are so powerful is that they have a lot to do with the acceleration provided by the repulsion. Secondly, auxiliary spiritual rituals are arranged on the shells made of spiritual materials, and finally the shells are given characteristics such as penetration and explosion.

Materials are one of them. The complex rituals in the later stage are extremely labor-intensive.

The production of shells can be industrialized. As long as the materials are sufficient, as many as you want, there are as many as you want. However, each shell needs to be manually engraved with spiritual rituals, which seriously limits the output of shells.

Even if the vortex spiritual patterns are passed on to the grass spirits now, they will not be able to catch up with the current spiritual technology of the human race without dozens or hundreds of years of development.

With the resources supplied by the Grass Elves, the human race takes a cut from them, and the excess resources are enough for the human race to start great development again.
