Everyone waited on the top of the city all morning. Finally, when the sun rose to its highest point, traces of the insect swarm appeared again on the northern horizon.

"Here we come!" The reincarnations were ready. Ye Peng and Le Xinyi each operated a crossbow. Liu Mofei helped the weaker Le Xinyi, and Fang Tianhua took out the black crossbow and cocked the arrow, but there was no arrow on his crossbow. They were all processed and tied with bamboo tubes filled with black powder.

Just like yesterday's routine, as the insect swarm continues to approach, first the trebuchet's scattering bombs wash the ground, then the ballistae is used to deal with the insects rushing through the bombing, and finally the archers use explosive arrows to shoot!

And today's gunpowder weapons have many new tricks that incorporate fantastic ideas.

For example, there is one kind that is inspired by firecrackers by reincarnators. Twist the leads and cotton threads together and tie countless firecrackers together to form a large string of earth red enhanced versions!

Such a bunch of red earth was thrown into the swarm of insects using a crossbow machine that fired blades. The crackling small firecrackers could not kill a strong insect for a while, but interfered with its senses, causing it to run around in shock, carrying a series of The explosion disrupted the insect's charge and delayed time, allowing the archers on the city head time to shoot one by one!

Another one is inspired by the firecracker "Little Bee". Craftsmen made gunpowder into "little rockets" that could continuously spray, tied the rockets to large symmetrical blades, tied one symmetrically to each side, lit them and threw them into the insect swarm, and the big blades would Under the thrust of the small rocket, it automatically rotates like a top and rushes through the insect swarm. At least many insects can be killed before the gunpowder burns out!

There are many other clever ideas like this, some of which are useful, and some of which are just cute, but they all end up beating the swarm of insects to pieces and turning them upside down...

Similar to the day before, the insects could barely reach the city wall before being killed. After about an hour, the insect swarm could no longer withstand the power of gunpowder weapons and retreated.

After a short period of repair, around three or four o'clock in the afternoon, the insect swarm attacked again. After more than an hour of fighting, they retreated before the sun set.

After these two battles, each veteran has killed a lot of bugs, but they don't have Zhang Lang's portable counting system, so they don't know if they have killed enough and how many points they have earned. On the other hand, Zhang Lang stood at the top of the city with a big sword, but he had no use for it...

The fourth day passed safely. When we returned to the castle in the evening, the seniors enthusiastically described the power of gunpowder weapons to the newcomers, telling them how many bugs they had solved and how many points they had earned. Ready to move.

"How about we go up to the city wall tomorrow and get some points?" Wang Chufeng suggested. The other newcomers also nodded and expressed their willingness to try.

"If I were you, I would stay in the castle tomorrow!" Fang Tianhua suddenly said:

"I have never heard of a smooth mission. What's more, this time it's full difficulty for thirty-six people. If you can pass the level with just one gunpowder weapon, it would be too easy. There are still more than two days, I It is estimated that something unexpected will happen tomorrow..."

After hearing Fang Tianhua's words, the newcomers became worried again, and the voices on the top of the city became weaker again. Only Wang Chufeng looked at the seniors, as if they were thinking about something.

In addition to this, Professor Yuan Lili and Professor Yuan brought information about insects through dissection!

Knowing the news, Le Xinyi notified Zhang Lang and called him to the room of the reincarnators... As the strongest among the reincarnators, knowing the weaknesses of the insects will help him kill enemies better and complete the main mission. The completion of also goes a long way!

After everyone arrived, Teacher Yuan took out the notes he had taken:

"I have dissected many insect corpses left on the city wall in the past two days, including the most common mantis monster, the powerful purple gold war insect, and the dragonfly flying insects in the sky... Although they have different shapes, their structures are There are a lot of things in common, and it can be seen that they are probably the differentiation and metamorphosis of the same species of insect eggs!"

"Becoming...perverted?" Liu Mofei asked curiously.

"This metamorphosis is not that metamorphosis!" Shang Xue, a girl with short hair and glasses, said: "Metamorphosis is the change in the growth process of an insect. For example, from a maggot to a fly, a complete change in form is called metamorphosis!"

Yuan Lili nodded and continued:

"Although these monsters look like bugs, they are not ordinary bugs that are enlarged. Their body structures are very complex and advanced, but they are different from the large animals in our common sense. So they can grow bigger than humans. , but at the same time, they are not as difficult to kill as bugs with simple structures. Normal attacks can kill them as long as they damage the main parts of the head and trunk."

"In other words, these bugs are actually advanced creatures on another evolutionary line?"

"You can't say that!" Yuan Lili retorted: "At least there is one place where they are no different from bugs, and that is the brain! Their brains are as simple as bugs. I even think it is a complete waste for them to have such big heads. , because their brains should be as big as walnuts at most.”

"Then what's in their heads?" Liu Xingwei asked curiously: "Is it empty?"

"It's not empty. Most of the space is filled with a kind of oil-like substance. Similar to dolphins and whales, I speculate that these are used to receive ultrasonic waves..." Yuan Lili analyzed: "This kind of structure is usually used for remote sensing. Communicate over distance. But the brains of these bugs are not strong enough to support their use of language..."

"That is to say, these bugs are under command!" Shang Xue pushed up his glasses: "Like the bugs in many science fiction works, these bugs should also have a commander like a brain bug or a bug king. If we can kill them It might be able to save the situation!"

"Is it useful to say this?" Liu Mofei shrugged his shoulders: "Is it possible that we can still go out of the city to assassinate the Insect King? Besides, who knows where the Insect King is hiding?"

"We don't know where the Insect King is! But we can be sure that it's not too far away!"

Wang Chufeng laughed and said: "The transmission speed of sound is very limited, and the attenuation in the air is also very severe. If these bugs really rely on ultrasonic waves to transmit information, then the commander will never be too far away!"

"Isn't it still useless?" Liu Morfei sighed: "Even if it is right under the city, we don't dare to rush out and attack!"

Indeed, looking at the thousands of insect swarms covering the wilderness, both in number and individual strength, they are far superior to humans. Without the support of this city wall, humans have no chance of winning in wild battles...

Among the crowd, only Zhang Lang frowned slightly, thoughtfully...

Fighting into...the insect nest?
