Doomsday: Unlimited upgrades to the shelter

Chapter 144 Apple "Vacuum Cleaner"

Xie Yannan split open on the spot, and this special thing was even more outrageous.You must know that the system requires 1000 apple seeds, and he does not know the final calculation method of the system.

In order to avoid missing a few, he must pick at least 1000 apples.

This……

Xie Yannan couldn't help swallowing, although it could be collected with two sticks and placed on the ground, and then stored in the system.But this speed is too slow, it is purely human, and it cannot be completed in a few days and nights.

He was dumbfounded.

"Master, here I am."

Just when Xie Yannan was worried, Xiaoxiao suddenly appeared in front of him, which really shocked him.

"You... where are you from?"

Xie Yannan breathed a sigh of relief.

"I came here based on your positioning. There is a positioning in your body." Xiaoxiao said truthfully.

"What, is there a location in my body?"

Xie Yannan was stunned. He didn't think the positioning was similar to a chip or system. How could something like that appear in his body?

"I can perceive where you are, which I call positioning." Xiaoxiao nodded, giving a reasonable explanation.

This also meant that Xiaoxiao didn't enter the gate, what was the reason, Xie Yannan had to go back and ask Ma Wu for advice.

Xie Yannan paused and said, "Xiaoxiao, I want to pick the apples above. I guess you have to be faster. It's a bit troublesome to pick these apples."

He gave Xiaoxiao a simple explanation.

In the process of explaining, he suddenly realized that there is another possibility about Apple.

That is, the ground has been continuously providing nutrients to apples, or some kind of chemical substances, or energy.

If the apple tree is cut down directly and the source of this energy is cut off, the apples will not explode automatically, making apple picking easier and easier.

"Xiaoxiao, go and chop down the tree."

After receiving the instruction, Xiaoxiao walked straight to the apple tree without hesitation, quickly transformed her palm into a machete, and swung it at the apple tree with all her strength.

bang~
The sound was crisp, but there was no sign of any chopping on the apple tree trunk.

Only the branches shook a few times, and then calm was quickly restored.

Damn it, is there still no solution? !
Xie Yannan frowned, and didn't think of a better way for a while.

Can 1000 apples be picked with four hands?
"Huh, isn't that right? The leaves don't seem to fall off." Xie Yannan noticed that although there are so many apple trees, there is not a single apple leaf on the ground.

He stretched out his hand and tugged on the leaves, "Sure enough, the leaves don't fall, only the apples fall. If we can't pick or shake the branches, we can collect the apples directly by inhaling them. "

This method was learned by Xie Yannan in books. It is similar to the principle of a vacuum cleaner. With the help of the power of compressed air, the fruit is sucked into the funnel and sent to the container under the tree through a soft transmission tube.

The method given on the tree is for each fruit one by one.Since the leaves will not fall, Xie Yannan can collect the whole tree together.

[System exchange and assembly...]

This thing is very simple. Xie Yannan knew that the system did not have this finished product, so he had to buy raw materials from the system and assemble it himself.

Fortunately, raw materials are plentiful.

He paused, took the assembled hose, pointed the funnel at the apple tree, and had the opportunity to completely cover the entire apple tree, and started the air compressor again.

Only a rumbling sound was heard, and the whole machine started to run.

Xie Yannan could completely feel the apples being sucked into the funnel one by one, and then rolling down the hose to the ground.A tree that was originally planned to take an hour or two to pick was picked in less than 10 minutes using this machine.

While he was picking, Xiaoxiao was also carefully manual picking.

Xie Yannan didn't bother to count the apples pushed up on the ground, guessing that they were almost there, so he sat down on the ground, wanting to take a rest.

Xie Yannan smiled, this time the charge is quite reasonable, just counting apples, this huge amount already gave him a headache.

He took a nap, and after a short nap, he heard the sound of the system completing.

[Number of apples: 1013]

Anyway, Xie Yannan didn't dare to touch this apple, but it looked like it was very powerful, so it would be useful to take it back.Besides, the tasks assigned by the system must be saved back to the system to be considered completed.

[The system announces that the task of collecting apple seeds is completed, and the system rewards a concept weapon, please use it with caution]

Unexpectedly, the system was so sensitive, and the concept weapon was immediately delivered to Xie Yannan's hands.

But, this...isn't this just a highlighter?
Xie Yannan looked at the little thing in his hand again and again, it was about a centimeter in length, and its appearance was no different from that of a pen.

It's just that this pen has no refill, and a transparent triangular pyramid is raised where the refill should have been.

There is also a dense row of small characters engraved on the pen body, which are instructions for use.

[Point the transparent pen at the object you want to test, press the switch, and the concept weapon will automatically produce a mixture of sound waves and light waves. The two waves are mixed and emitted to interfere with the opponent's thinking factors to achieve your own goals. 】

It turns out that this is the working principle. Sound waves and light waves have different wavelengths, and they can actually be mixed and emitted together.These are things Xie Yannan has never studied in textbooks before.

He carefully stored the conceptual weapon in the system, and the reason why he wanted to take the risk to complete this task was to test Ma Wu.

I always feel that Ma Wu is too extraordinary and seems to be the biggest threat to Pengu.

He got up, patted the human bones sticking to his buttocks, and was about to activate the door of the system, and went back to the valley.

He couldn't take Xiaoxiao away, so she could only find a way to come back by herself.However, with her ability, Xie Yannan has nothing to worry about.
