Of course, compared to the immortals, it will be easier to coexist peacefully with the humans of this world, provided that Xie Yan has the ability to fight back with nuclear weapons.

But grow mushrooms......

As far as Xie Yan's college head is concerned, he really can't grow it, and even if he knows the formula and keeps repeating the experiment, he may not be successful. Because, this is not the earth! It's another world, another time and space, and if you want to grow mushrooms in this world, you have to apply the theoretical system of this world!

So he had to find another way to create something that was comparable in power to mushrooms.

There are two methods, one is to rely on fruits with infinite possibilities, but he knows that if he wants the fruit to develop into that kind of thing, it will have to be conceived for five, six, seven, or eight years.

And if you want to speed up the time, it is useless to rely on energy alone, you can only infuse the fruit with a higher concentration of aura, such as a completely concentrated liquid aura!

Even so, it's good to be able to cut the cycle in half, half in five years, and two and a half years!

The second way is to rely on diligent hands and a body that can be transformed at will, after all, the fruit and Xie Yan's ability should be the same, in this case, what the fruit can convert, in theory, Xie Yan can also make it himself!

Of course, if you want to do it on your own, you must solve some fundamental problems. For example, technical and material issues.

Let Xie Yan imitate the field of vision blocker and create another one, he can't do it! The materials used in the field of vision jammer, the internal manufacturing process, the black technology, etc., he can't imitate any of them!

So he has to do scientific research and find ways to come up with matching materials and related technologies.

Xie Yan has always believed that if mass production cannot be achieved, then there is no talk of the word "combat effectiveness"!

However, engaging in scientific research is a long-term process, and there is no rush now, and now Xie Yan must first arrange the basic weapons. For example, the ejection poison mist, animal traps, etc., which were used before, although these methods have been known by mysterious people, it does not mean that they are useless.

In addition, there are thorn walls, which Xie Yan made look like a green belt, and the reason why he did this was because he wanted to give the passing mountain people the illusion that this was artificially planted, otherwise the row of plants growing so neatly would definitely arouse suspicion.

In order to make it more realistic, Xie Yan also made some signs on the green belt, with signs such as "cherish life" and "look back at your family" to prevent this place from becoming a suicide forest.

These things took Xie Yan more than half a month, and he didn't stop to catch his breath, and immediately began to research new weapons!

"Ask for one, you can move! Requirement 2: Be flexible! ”

Xie Yan gave himself two indicators.

Of course, Xie Yan is not immobile now, but he can only rustle and shake like this, and then scare out a group of tricolor bees that are looking for larvae......

The queen bee also flew out, holding the eggs she had just laid on her hind legs, with a sad expression.

Before the next shake, can you say it in advance?

Therefore, it has always been Xie Yan's wish to make his body move, otherwise every time a mysterious person comes to attack him, he can only watch dryly, without any room for operation, this feeling is very uncomfortable!

At the same time as issuing the indicators, Xie Yan already had some preliminary ideas.

He first picked a grimace tree and made a vine several meters long and the size of a baby's arm on this grimace tree, and then made four blowholes in different directions of the vine.

"I'll call you a jet vine for now!" Xie Yan gave this weapon a name, of course, whether it can be put into use or not, we have to try.

So, he began to fill one of the vents with poison gas, and when the gas was almost full, he let the vent open slightly, and the poison gas was released instantly. At the same time as the poisonous gas is released, the ejected gas creates a counterthrust that pushes the vines in the opposite direction.

It looks like it worked, but it's ...... power It's probably the same level as a balloon that has leaked air and runs around.

Xie Yan shook the branches dissatisfiedly, which was too much worse than he imagined!

He was a little unwilling, and poured poison gas into it again, until the vines swelled and deformed!

"It's okay this time!" Xie Yan let go of the vent, and a large amount of poisonous gas gushed out, pushing the vines forward.

The effect is a little better than just now, but the vines that spew out are still not hurtful, probably at the same level as a slap......

"Why is the power so poor...... Xie Yan was a little surprised by this, "It seems that it needs to be improved!" ”

After thinking about it for a long time, Xie Yan had a new idea, add a few more jets to the vines, and then inflate them uniformly and release them together!

Call~

The vines pumped out the wind in the air!

Xie Yan was excited, looking at it like this, it seems feasible!

But then comes another problem - the frequency of attacks is too slow!

The Jet Vine is inspired by the horn vent in the catapult mist, which has a deadly problem with inflation speed.

In the wasteland, due to the lack of resources, the inflation speed was very slow, which made Xie Yan have to give up the idea of a horn spout at that time. Although I am rich now, the inflation speed is still very slow, and it takes about half a minute to fill it once.

On the battlefield, every second counts, let alone half a minute?

There are not no ways to remedy it, such as by increasing the number of vines, or by finding a more suitable gas.

"Why don't you try it with Reiki?" Xie Yan had an idea, and he released the poisonous gas in several vents, all of which were replaced with aura. And when he was about to release it, he hesitated for a while with some uneasiness, and then gritted his teeth, let go of these spiritual qi, and extracted a denser mist spiritual energy from the spirit storage bag and poured it into the vent.

Release......

Boom!

The sound of a huge explosion resounded through the mountains and forests, and if all the birds had not been driven away by Xie Yan, there would have been a spectacular scene of ten thousand birds taking off at this time.

Looking back at the scene, a small crater appeared in the center of the explosion, and the vines were torn apart, leaving only a small section still hanging from the grimace tree.

"I'm dripping ......" Xie Yan was shocked, this power was inevitably a little too terrifying.

The shock was followed by a burst of ecstasy, and the branches and leaves trembled.

The queen bee flew back to the nest in a rage, and the old lady is not giving birth today!

Xie Yan ignored the angry queen bee, and the unexpected explosion of the mist-like aura brought him a lot of inspiration, and at this moment, countless new ideas appeared in his mind.

"Come one by one!" Xie Yan took a puff of carbon dioxide, and his heart was full of confidence! Even, he was a little looking forward to the scene when the mysterious man sent troops to attack, and was hit by his new weapon.

"Ahem~ a little floating......" Xie Yan put aside the unrealistic obscenity in his mind and prepared to make further improvements to the vines.

He wanted a flexible vine, not an aura bomb.

Of course, the aura bomb is not impossible to consider, but you have to eat it bite by bite, anyway, there are still more than three months before the estimated attack time, and there is an opportunity for experimentation!
