I am a Parasitic Flower

The attackers that appeared this time had already reached the bronze and silver ranks, so next time they must be above the silver rank, or even more difficult to deal with humans!

And if you think about it carefully, you will find that the latter is more likely!

After all, reaching the Bronze level at this stage is already very remarkable. Where can the mysterious person find so many silver-level mutant creatures?

Xie Yan's advancement to the silver rank was all due to his own ability to transform and proliferate. Ordinary animals and plants couldn't use half of the aura of the mountain for their own use like him.

Even so, it took him months of back and forth to get from Bronze to Silver!

Therefore, in order to ensure the size and strength of the attacking team, the mysterious man will most likely confuse humans, at least in Xie Yan's view, he will do so.

In that case, let's treat the imaginary enemies as human beings. Anyway, we will contact them sooner or later. Xie Yan secretly said.

Whether it's peaceful negotiations or big fights, he must have the ability to counterattack at the mushroom level. Only with this level of lethal weapons can he have the right to speak and take the initiative.

In addition, he must also have the ability to fight against conventional weapons. He can't fly a helicopter and have large-scale weapons to fight back...not to mention waste, and he may hurt himself.

Then come on.

Xie Yan shook his body and started a new round of expansion tasks.

There is also the old saying that explosive soldiers start mining first, and only when resources are sufficient can we talk about scale.

Xie Yan started to take root, and this time, he was going to use a new rooting strategy. Generally speaking, his rhizome can be divided into three types, main rhizome, sub-rhizome and root hair. In terms of absorption efficiency, the root is greater than the sub-rhizome and equal to the main rhizome, and in terms of transmission efficiency, the main rhizome is greater than the sub-rhizome and greater than the root.

The problem Xie Yan encountered last time was that the absorption efficiency of the roots had reached the upper limit, so this time he prepared copper-colored energy to make roots and cyan energy to make sub-rhizome.

As for the main rhizome, it is already silver, so there is no need to make changes for the time being.

Not long after the expansion started, Xie Yan encountered the first problem, the psionic energy in the energy storage bag was too little!

Things like energy and psionic energy are like water pressure. The more the quantity, the faster the growth rate of branches, leaves and roots will be, and the smaller the quantity, the slower the growth rate will be.

Before, he only used ordinary energy to expand. In this case, as long as the root system is large enough, photosynthesis can keep up with these two points. And if you want to use psionic energy to expand, then you need to meet more than the above two conditions. After all, compared with the energy that can be used directly, psionic energy must be converted into an energy storage bag before it can be obtained.

Looks like it's time to build a warehouse. Xie Yan secretly said.

So he could only temporarily abandon the development plan of the green stem and copper beard, first expand the ordinary root system, use the energy to generate a set of basic conversion facilities, and then expand.

Xie Yan started to grow ordinary rhizomes, and shook off the old leaves on his body, replacing them with new ones. After doing this, he gave birth to the first eye plant ten meters away from his body, making it thicker and longer. Leaves are not scattered, and eventually a large tree without leaves is formed.

After that, he started to generate energy storage sacs on the tree, one, two, three... until the whole tree was stuffed to the brim.

After that, he spawned another big tree on the other side, which was also covered with energy storage bags.

The one on the left is called the green tree, and the one on the right is called the copper tree. Xie Yan chose a name for the two books.

The conversion factory is established, and the next step is to pour a lot of energy and spiritual energy into it. When the energy storage bag on the green tree is filled with green spiritual energy, Xie Yan will start to produce branch roots, and wait for the energy storage bag on the copper tree to be filled. With copper-colored psionic energy, he began to grow roots.

When the copper whiskers appeared in the soil, the speed at which Xie Yan absorbed nutrients skyrocketed! The efficiency is several times faster than before!

Taking advantage of this opportunity, Xie Yan brought out some green and copper trees.

After he felt that it was almost done, the expansion officially began!

One eye plant after another was inserted, and the two-color rhizomes began to invade the soil. Because there is no need for any miscellaneous camouflage, it doesn't take too much energy to expand, just insert the eye and take root, and the expansion speed will fly quickly.

With more and more eye strains, Xie Yan's field of vision became wider and wider, which allowed him to see the surrounding area clearly.

This is a valley surrounded by mountains on three sides. The left and right sides are quite satisfactory, but the mountain in the middle is special. It looks like it has been cut from top to bottom by someone, exposing a white rock wall.

The position of Xie Yan is just under this mountain wall.

In addition, there is a small stream in the middle of the valley, the stream is trickling, attracting many animals that come to drink water, such as the big stupid bear...

The source of the stream is on the mountain wall behind Xie Yan. There is a big gap there, and a large amount of spring water flows out of the gap. Since it has just rained a few days ago, there is plenty of water in the gap.

It is worth mentioning that the tricolor bees also put their new home on the cliff, and before building the nest, the queen bee specially sent a group of worker bees to measure the height and arm length of Huaxiong to ensure that the new nest should be built on the cliff. The place where the bear can't reach, so as not to turn around and be harmed again.

Xie Yan continued to expand outwards until the forest outside the valley stopped.

So if you want to enter this valley, there are three ways to go! The first is to enter from the forest outside the valley, the second is to enter from the path I came from, and the third is to climb over the mountains on both sides , come down from the mountain.

Of course there is a fourth one, which is to jump off the cliff behind Xie Yan...

Then the focus of defense is on the exit of the valley, the path I came from, and the hills on both sides.

Wait, since this place is so wide, why don't I build a city? Then create a long-range weapon and set it up on the city wall to shoot?

If the resources can keep up, I can make another outer city, double defense! I can even build an urn city at the entrance of the valley and the passage path!

Thinking of this, Xie Yan shook the leaves excitedly, It is possible, this idea is absolutely feasible!

He doesn't need to put on any camouflage now, all resources can be spent wisely, the soil is quite fertile, and there will be no shortage of light and water!

This is the ideal base! Xie Yan was overwhelmed.

Of course, the road has to be taken step by step. For example, first make the shooting weapon?

Xie Yan moved out several previously abandoned research projects.

Then let's build a cannon first! Xie Yan rubbed the leaves and began to conceive.

The principles of guns and cannons are similar. They all pressurize the barrel or barrel through the combustion of gunpowder, and then give the bullets and shells initial velocity. The barrel is divided into rifled and smoothbore. Rifling has high precision, but it is difficult to manufacture, while smoothbore has low precision, but it is easy to manufacture.

In addition, you can also add fins to the shells to improve accuracy, but you can choose one of the rifle and the fins, and there is no so-called superposition effect between the two.

As for which one to choose, it depends on the difficulty of the process and the manufacturing price. Generally speaking, rifles are used for firearms, because the barrel is small and it is relatively simple to manufacture rifles, so the bullets do not have fins. The cannon is long and thick, and it will be very troublesome and expensive to make a rifle, so the shell has a tail!

Of course, these are the situations of human beings. Xie Yan doesn't have any difficulty in making it here, he can make it as he wants. Still, he decided to follow the example of humans, using rifled guns and smoothbore shells.

In Xie Yan's opinion, it is better to unify the standards of weapons and equipment.

Of course, it is easy to say, but it is actually very difficult to do. Xie Yan soon ran into a problem.

It's really not that simple. Xie Yan sighed.
