After many days, Xie Yan finally expanded his root system to the limit.

At this time, the farthest straight-line distance he could see was forty meters, and the breadth was thousands of square meters, and the huge underground root system was jaw-dropping.

In order to make it easier to manage, Xie Yan formed all the eye plants.

The first echelon is the pro-guard, a total of five, four of which are in the cave and one is at the entrance of the cave. These five were armed to the teeth by Xie Yan, and their bodies were covered with spikes, and the spikes of different eye plants intertwined with each other, forming a wall of thorns at the entrance of the cave.

If you look closely, you will find that these spikes are blood-red and extremely charming. This is because Xie Yan infused it with a powerful toxin left by the fruit, because the toxin was extracted from the blood of the ox, so Xie Yan named it the ox blood poison.

Next is the second echelon, with three plants, distributed five meters from the entrance of the cave. This echelon is the production echelon, and each plant has four green leaves on it, which is used for photosynthesis, and there are also burrs and pores on the offensive and defensive sides, which is enough to make small insects sigh.

Further beyond are five plants in the third echelon, six plants in the fourth echelon, and nine plants in the fifth echelon. These 20 ramets currently have only the most basic eyeballs and have no additional functions.

However, Xie Yan had already thought about equipping the third echelon with a weapon with air defense capabilities, which were two closed flares, and once in danger, the flare would spew out a poisonous mist, forming a wall of poisonous gas!

This plan has not yet been implemented, and the biggest reason is that the bell cools down too long, and it takes three days to reload ammunition before it can be sprayed a second time. Secondly, this type of weapon has a large skin and a strong transpiration effect, and it consumes a lot of water every day when hanging there.

In fact, this kind of spout Xie Yan originally wanted to be installed on the first echelon, after all, the four plants of the first echelon are not exposed to the sun in the cave, which can lock in water to the greatest extent, but compared to the one-time poisonous mist, the stinger wall full of poison is a little more powerful no matter how you look at it.

"No, the spout is too, I'll have to do it another way." Xie Yan thought about it seriously, and suddenly, a small grass that he had played with in his childhood in his previous life came to his mind.

He didn't know what the scientific name of that grass was, only that the common name was Burst Grass, and the reason why it had such a name was because that kind of grass would wrap the seeds in the pod, and as long as the seed sac was touched or when the seeds were ripe, the pod would burst open, and the seed bullets inside would be everywhere.

It is generally used for pranks, but it is very difficult to pick, after all, the slightest movement will be jumped into the seeds.

Xie Yan felt that he could use this idea, combined with the previous spout, to create a water-saving jet weapon!

So Xie Yan took one of the strains for experiments, first of all, he needed to grow a small sac that could explode, and there were two ideas.

One is an inflatable explosion, which is popped by pouring gas into the capsule, and this principle is used in the bell mouth. The other is deformation ejection, which is the same as a bow and arrow, and when needed, as long as you use a little force, you can shoot the bullet inside.

After Xie Yan tried both, he chose the latter, mainly because the pod was too small, and the inflatable explosion could not bounce the bullet inside far enough.

After many experiments, Xie Yan finally got it right.

It was a thumb-sized thing that looked like a pea pod, and at the slightest touch, the small pea pod would burst open, and four bullets placed inside would eject.

The so-called bullets are actually very small flares, which are full of low-boiling venom, and when the bullets are fired, they rub against the air to generate heat, which promotes the vaporization of the venom, and then makes the small flare burst open.

"I'm a genius!" Xie Yan waved eight aura leaves, "In this way, the third echelon will be done, followed by the fourth and fifth echelons." ”

The fifth echelon he already had an idea, as a part of the city wall, what would be more powerful than thorns? So Xie Yan decided to build a wall of thorns. The plan had been shelved because of the conflict between the Thorn Wall and the Trumpet, and it was impossible for him to combine the two due to his lack of resources. But now that the bell mouth has been improved, the Thorn Wall project can naturally be put on the agenda.

Then the last thing that needs to be considered is the fourth echelon.

"The current defensive lineup can already ignore insignificant things such as ants and caterpillars, and even if I encounter the previous yak, I have a stinger wall in my way."

"Even an imaginary herbivorous dinosaur will be poisoned by the stinger wall, and once it dies, such a big head can directly plug the hole, but can help in defense!"

"So there is no threat to me for individual and small groups, and what I have to think about now is how to deal with large groups!"

For example, herds of cattle and sheep.

Once these things are not afraid of life and death, they will bring great pressure to Xie Yan's fortifications!

……

"Handsome guys, I like the little sister to brush up the lighter plane! The one who gives the most gifts, I'll go to you offline! mua！ ”

Li Yinsheng looked disgusted, he handed the screen to Zhou Qing and asked, "Guess how many layers this girl has on her face?" ”

"Light makeup, just a filter." Zhou Qing shook his head, "You know it's a bewitching slut, still look at it?" ”

"Just got it...... Look at this! ”

"I'm driving!" Zhou Qing looked impatient.

"Tsk, there are not many hairs on this wasteland, so you can be afraid of anything!" Li Yinsheng glanced at him with disgust, and then swiped out the next video and watched it with relish.

Zhou Qing took a deep breath, "Corporal Li Yinsheng, let's carry out the mission!" Is it okay to put your phone down? ”

"Yes, Captain Zhou Qing." Li Yinsheng said in a weird way, and then reluctantly put down the phone.

"Okay, let's find another day, and if we still can't find it, we can go back to the town to resupply and rest." Zhou Qing rolled his eyes.

"Haha, it's worthy of being my captain, and you know my heart well." Li Yinsheng changed his previous frustration, "But then again, how long has it been, we haven't found the wrong place, right?" ”

They were sent by the higher authorities to investigate a riot a few months ago, not man-made, but animal!

According to the residents of the local town, the night before the riots, they smelled a very strong scent of flowers, which was very pleasant and intoxicating.

What these villagers don't know is that there are two young people who have not woken up because they have been overly intoxicated by the aroma!

Zhou Qing didn't answer, at this moment, the encrypted phone on the side rang, he glanced at the number, it was a call from his boss. Zhou Qing pressed the answer button, communicated with his boss, and hung up the phone.

"Looks like your plans for rest have gone up in the air." Zhou Qing said expressionlessly.

"Why?"

"The two children who fell into a coma because of the inhalation of the aroma, wake up!" Zhou Qing said, a gleam flashed in his eyes, "The moment they woke up, they directly awakened into deviants. ”

"Really?" Li Yinsheng's eyes widened.

"So I gave a death order from above, even if it takes a year and a half, I must find the source of the fragrance!" Zhou Qing said.

Although as the aura becomes more and more intense, there are more and more awakened people, but it is based on a population of more than one billion, and everything has a contingency, those who are in high positions, no one wants to be the unfortunate "what if", and no one wants to leave early in this wave of tide because of some objective factors.

For them, they can become deviants one second earlier, and never delay one second!
