"These soils are actually vermicompost manure, which is very suitable for plant growth, and it is very troublesome for me to collect these things, and it takes cost and time to transport them, so I would like to ask if you can provide some more reliable means of transportation here." Xu Fang asked.

"In that case, is it okay for a solar-powered cargo vehicle?" asked Ma Li.

"What is that?" Xu Fang asked in surprise.

Ma Li also realized that Xu Fang's planet was not so advanced in technology, so she took out the remote control and clicked on it, and a screen suddenly appeared on the wall.

"Picture of a solar cargo aircraft!" Ma Li said to the remote control, and then a picture of a solar aircraft appeared on the screen.

Xu Fang looked at it, this thing was very similar to a helicopter, but it was bigger.

"How do I use this?" asked Xu Fang.

"It's very simple, as long as you are positioned, it will automatically fly and avoid all hazards. The load aspect is not too prominent, and it can carry fifty tons at a time. The speed is very fast, 1,000 kilometers per hour. The energy consumed is electricity, solar power. Its fuselage is full of solar energy-to-electricity devices, and if not in use, solar energy is stored in batteries, so that it can fly at night. The utilization rate of solar energy is high, so there is no need to worry about the lack of energy at all. Ma Li explained to Xu Fang.

Xu Fang was overjoyed when he heard this, and exclaimed, "This is okay!"

Ma Li glanced at Xu Fang and hesitated before saying: "This kind of cargo aircraft is very precious, including our Tianqiong Prefecture is also rare, this is all unified by the state, and there are only two in the entire Tianqiong Prefecture." ”

Hearing Ma Li's words, Xu Fang understood what this woman meant, and smiled: "I can exchange this for something." ”

Seeing Xu Fang doing this, Ma Li suddenly became happy: "No problem! Do you have any other conditions?"

"The other conditions are gone, and now we can officially talk about cooperation. The plants I grow all cost money, I don't know how the beautiful governor wants to exchange them with me?" asked Xu Fang.

Ma Li frowned, she knew very well in her heart that a planet with backward technology had a strong dependence on technology. His advantage is also that he has mastered a lot of high-tech products, but the value of things on the two planets is not the same, who knows how big this kid's appetite is?

However, as the governor of Tianqiong Prefecture, Ma Li's IQ is very high, and after thinking about it, she looked at Xu Fangwen and said, "I don't know what you need, what you need can be mentioned, and then we will negotiate the price." ”

"I am very interested in the solar-powered aerial vehicle you just mentioned. Can you transfer to me the technology of solar energy to power quickly?" asked Xu Fang.

Ma Li was stunned when she heard this, but she didn't expect Xu Fang to hit this idea.

Although she can find this kind of high-tech secret, she can casually transfer it to others, which is not something she can afford.

In an instant, Ma Li fell into deep thought.

Xu Fang didn't urge, just sat aside and waited patiently.

After a long time, Ma Li looked up at Xu Fang and said, "Xu Fang, your request is very difficult, because this kind of high-tech technology is a state secret, and it is impossible to transfer it to you casually." I said that a request is feasible for you to see, when you plant all the plants in Tianqiongzhou, I will give it to you, how about it?"

Xu Fang almost vomited blood when he heard this, looked at Ma Li and said frantically: "Governor, don't you have a little pressure in your heart about how large the area of Tianqiong Prefecture is? How young is it after planting? My bottom line is Tamar City, and when Tamar City is full of green plants, you will give it to me." ”

Ma Li quickly calculated in her mind that the area of Tamar City is not small, and if it can be planted with green plants, it can effectively improve the local environment. And the Sifang Kingdom has a lot of high-tech technology, although this technology is very precious, but she still has more technology to attract Xu Fang, and immediately nodded and said: "Okay, then let's make a decision!"

"Well, also, from now on, I will plant a square meter of green plants, maybe a tree, you all need to give me a bottle of plant growth liquid, this is no problem, right?" Xu Fang looked at Ma Li with burning eyes.

"No problem!" Ma Li nodded, the plant growth liquid was very easy to get, and she was surprised that the price was so low that she could exchange it for plants so cheaply. However, his face remained silent and continued: "By the way, the previous solar cargo aircraft is also very valuable, and this will be exchanged for 100,000 square meters of green plant planting area. ”

"Yes!" Compared with high-tech flying machines, Xu Fang felt that the price was already pitiful.

After saying this, Ma Li also sat up straight and asked solemnly: "Xu Fang, there is also food you have there, you can also exchange things with me, do you want to exchange it?"

Xu Fang thought about it, this can indeed be available, and immediately nodded: "Okay, when I come back next time, I will bring some food that can be carried for a long time, and then we will discuss the price specifically, how about it?"

"Okay, okay!" Seeing Xu Fang's agreement, Ma Li suddenly cheered up.

"By the way, Xu Fang, some fruits are grown from fruit trees, right? Can you plant some of these plants?" Ma Li suddenly asked.

Xu Fang secretly sighed in his heart that this woman was smart, but he didn't agree, but looked at Ma Li Zhengse and said: "Governor Beauty, the natural environment of Azure Star is very harsh, and the soil has become barren. The plants I grow now can change the quality of the soil. Over time, the original soil can gradually rejuvenate, thus changing the natural environment little by little from the source. If something else is planted, it is likely that the effect of improvement will be reduced. ”

"You can plant less. Ma Li said hurriedly.

"Yes, the price of the fruit trees is not counted. Xu Fang nodded.

"If the fruit trees can be planted alive, you will be given three bottles of nutrient solution each. Ma Li said.

"Yes, you can. Xu Fang has no problem with this.

The two chatted with each other for a long time, and after determining the price of cooperation, Ma Li began to find the base he wanted for Xu Fang.

This kind of place is not hard to find, and there is even one nearby. Ma Li drove Xu Fang and came to a gymnasium after a while.

"This gymnasium is abandoned, and it was going to be demolished, can you take a look? If you can, I'll make it a secret base for you. Ma Li said, pointing to the building in front of her.

Although there is only one floor, the first floor of the gymnasium is also very high, so there is a lot of room for it. Xu Fang went in to take a look, it should have been a basketball court before, but the basketball court shelf was gone.

It covers an area of more than 10,000 square meters, which fully meets the current needs of Xu Fang.

"Xu Fang, are you still satisfied with this place?" asked Ma Li.

"Very nice. Xu Fang did not deny it.

"Then I'll teach you how to use the cargo plane, and hopefully get the plants over as soon as possible. Ma Li said happily.

With cargo aircraft, transporting vermicompost is much easier when several earthworm farms are far away, but with sufficient energy and fast speed. Besides, Xu Fang was also very interested in this flying machine, and hurriedly followed Ma Li to learn the operation of the flying machine.
