"What? Acacia trees? Ye An rubbed his ears, suspecting that he had misheard.

"It's just an abbreviation, the host doesn't need to make a fuss, this acacia tree has nothing to do with the bitter tree that the host knows."

"Oh, that's it......" Ye An calmed down when he heard the explanation of the system, he really confused the bitter tree with the acacia tree, and thought that the system wanted him to plant a bitter tree...... That thing doesn't grow in years.

"Then the question is, I'm just going to open a branch school and plant trees for Mao?"

The system explained: "'Acacia tree' is only a tree as a carrier, and its essence is the latest new energy signal base station, please don't underestimate it!" ”

"Okay, what's the use of this thing?"

System: "The role of the signal base station is naturally to diffuse the signal, and the host wants to establish a branch campus first needs to consider a problem: how to make the function of the system cover the area where the branch is located? ”

"Huh?" Ye An was a little confused, "What other functions does the branch need to have?" ”

System: "Would you like to ask the host to give the branch a little more attention?" Host: Should you use the building system to help build a house for the school? And the host doesn't plan to open the campus supermarket on the campus? Even if the host of these things feels unnecessary, the campus network system is always indispensable, right? ”

"I see!" Ye An suddenly realized, "The key to the problem is that you alone can't cover the whole continent, right?" ”

"......" Ye An said this, Lord System was unwilling, but he was powerless to refute: "Host, you have to understand it like this." ”

"Okay." Ye An skipped this stubble, "Then how to raise this acacia tree?" Watering and fertilizing? ”

System: "Of course not, the answer is already hidden in the full name of the Acacia tree...... Acacia Tree, the full name of Shangri-La Sineng Signal Tree, is a new energy source 'Sineng' newly applied by the Time and Space Administration as the power source, which is pure natural and pollution-free and non-residue! ”

Ye An suddenly felt tall, since it is a new energy, it must be better than wind energy and solar energy, right?

So Ye An asked reverently: "How are you going to do this 'Si Neng'?" ”

The system explained: "'Thinking energy', both for the 'energy of thought', since the host has been in contact with Kewpie, should also know their theory, junior high school textbooks have mentioned that energy is conserved, but in fact, although the total amount of energy is conserved, but it is also divided into usable and unusable, so the conservation of energy is also relative, energy is indeed conserved for the entire universe, but for the creatures living in it, the total amount of energy is constantly consumed!" To talk about why some energy is not available, we have to mention the concept of 'entropy' that Kewpie has been emphasizing, first of all, let's talk about the definition of 'entropy'......"

Ye An's head was already big when he heard a short passage of this passage from the system, and when he heard what "entropy" she was going to talk about, he quickly interrupted: "Stop, stop!" Is it okay to just say the conclusion? ”

The system is dissatisfied: "Can't you learn better from the host?" What is the difference between a host that doesn't learn and a salted fish? ”

"! Didn't you say that you were only responsible for tutoring below high school? You're clearly out of the box now, okay! ”

"Humph! Shallow! Knowledge about entropy is only junior high school in your country! ”

"Damn, my country is so terrifying?"

The system knew that this topic could not be further deepened, so it turned back in time: "Forget it, when there is time, the system will come back to make up for the host, and then let's talk about the conclusion directly." Continuing from the previous topic, the consumption of energy has become a serious problem in the future, and the civilization where Kewpie is located has thought of providing energy with human feelings, and we humans have also found this direction, which is the application background of 'Si Neng'. ”

Ye An wasn't interested in the background or anything, what he wanted to know was how to extract the energy called "Si Neng"!

He asked expectantly, "This energy should be convenient, right?" ”

"No!" The system ruthlessly broke Ye An's illusions: "I told the host so much before just to let the host know that 'Sineng' is important in its strategic significance!" It's actually a lot more troublesome to use than solar energy! What the host needs to do is for the members of the academy to receive the 'burst of thoughts' within the sensing range of the acacia tree, so that the acacia tree can absorb the 'thoughts and energy'. ”

“...... If it's so troublesome, why don't you change it to a solar for me? ”

"Hey! If you can be environmentally friendly, don't waste it! The system vibrated with words: "Host, do you know how much trouble your predecessors' profligacy has caused to future generations?" ”

it! It's not eco-friendly! Don't talk to me about this!

Ye An was already weak: "Then what is this 'outburst of longing'?" ”

"This is also more abstract, for example, 'I want to go crazy with people', or 'reunion and reunion' or something like that."

"! It's troublesome to think about! Can't you guys make a simple and easy-to-understand spit energy device or something? ”

"Spit Energy Device...... That's alien technology, and our Temporal Authority's budget isn't enough......"

It's a sad story to be mixed up like this in the future.

Ye An pulled the skin with the system for a while, and finally understood the working mechanism of the acacia tree.

Acacia tree is not only one, it is a complete system, there is a main tree and a branch tree, its relationship is like the teacher machine and the student machine in the computer class, the teacher machine can check the status of the student machine, control the function of the student machine, and the student machine provides services for students under supervision.

If Ye An wants to build a branch school, he must first establish the main tree of the acacia tree in the school as a teacher machine, and then plant a branch tree as a student machine at the location of the branch.

Some people may be puzzled, the campus supermarket is not Ye An....... Sportswear as a carrier?

In the front, this is true, but in fact, the shipping location is not fixed, if the acacia tree is cultivated, then the acacia tree can also replace Ye An's sportswear and become an automated campus supermarket.

Of course, Ye An will not be stupid to sell everything, and he has to decide what the specific goods are.

Ye An shook his head and went out, he was going to wait for another day of the awakened person and then go back, there is still an acacia tree waiting for him to plant in the academy, and I won't be able to wait!

As for how to collect "Sineng", he already has an idea......

"Isn't it just to reunite them...... Well, the most important thing in a family is to be neat and tidy. ”

Although he said it lightly, only Ye An himself knew how much his heart hurt.

"! If only the energy could be used...... This Shilaozi's longing energy costs a lot of money! ”
