In fact, when it comes to fertile fields, the first thing that comes to Li Feng's mind is chemical fertilizer. Pen, fun, pavilion www. biquge。 info

And the king of chemical fertilizers is naturally Jin Kela......

The sentence that Africa's agriculture is underdeveloped, Dongying's resources are too scarce, and the brainwashing advertising slogan of Jin Kela's must be used has already spread all over the country.

However, although Jin Ke La is good, it has many disadvantages, such as easy loss and easy to cause environmental pollution.

Li Feng has the intention of building the farm into a pollution-free industrial base, so naturally he cannot use chemical fertilizers casually.

In this case, organic fertilizers can only be considered.

When it comes to organic fertilizer, many people will subconsciously think of heavy things such as human and animal manure like little slaves, in fact, there are many types of organic fertilizer, such as green manure made of pure plants, and some compost made of waste debris, which are common good organic fertilizers.

However, these organic fertilizers, the production process is relatively troublesome, and they are not Li Feng's favorite choice.

The most suitable target that Li Feng thought of was the silt of the fish pond.

The freshwater fish farming industry in the Lingnan region is very prosperous, and large-scale dredging operations are carried out every 10 years or so...... And those sludges, as long as they are treated with heavy metal removal and fermentation, are good organic fertilizers.

Cheap, large in quantity, widely sourced, and meets the requirements for large-scale use.

"Speaking of fish pond silt, the fish pond in my hometown village is about to be desilted, and it will not be difficult to get the silt for free when the time comes, the only question is, how can I get such a large amount of silt into the farm space?"

Li Feng can only carry his personal belongings in and out of the farm space now, and he can't bring too many things for the time being.

"It's a pity...... Such a large piece of land, wouldn't it be useful!"

Just when Li Feng was regretting, the little slave suddenly shouted excitedly:

"Master, master, the World Tree has opened the bark barrier!"

Li Feng turned his head to look over, and found that the little slave pointed to the World Tree, with a happy face, and then looked at the World Tree, on the trunk with a diameter of nearly ten meters, there was an extra blue light vortex.

"What is that?" Li Feng looked surprised, is this World Tree still conscious?

"That's the passage into the interior of the tree world!" the little slave couldn't hold back his excitement, "Master, we can go inside the tree world!"

"What a tree world...... Is it big inside?" Li Feng was a little confused, he thought that the title of the World Tree was just a name with exaggerated grammar!

"Your World Tree is just a seedling, and the Tree World won't be ......very big," the little slave said excitedly, "Otherwise, let's go in and have a look!"

"Go in and have a look?" Li Feng was a little moved, but remembered the risks of talking about the floating island, so he couldn't help but ask, "There won't be danger in the tree world, right?"

"Of course there is no danger, this is your World Tree!" replied the little slave subconsciously.

Li Feng thought about it, how could his own tree be in danger?

"Then Xiaobai want to go in with you?" Li Feng suddenly looked at the beetle snake and asked.

The beetle snake subconsciously wanted to follow up, but after thinking about it, since this kid deliberately asked this, he obviously wanted to stay and take care of the house......

"I won't go in, the territory will not be guarded. "The beetle snake looks righteous and awe-inspiring.

, this guy's consciousness is quite high! Li Feng, who was still thinking about how to persuade the beetle snake to stay, was a little surprised.

"Then Xiaobai, you take good care of the house, I will give you credit......" Li Feng looked like a leader, and originally wanted to pat Xiaobai on the shoulder to show his attention, but found that the beetle snake had no shoulders at all, so he had to give up.

Cut...... I'm not going to go in and see by myself when you're gone!

The little slave took Li Feng to the whirlpool passage of the World Tree, slowly raised his little hand, and gently pressed it on the thin layer of green mang.

In the next moment, a green light flashed in the middle of the whirlpool, quickly rolling Li Feng and the little slave in.

Li Feng only felt the light flashing in front of him, his body sank lightly and again, and with a bang, he stood on the ground again.

Looking around, what Li Feng saw was an empty cylindrical space, with a diameter of thirty or forty meters, and upward, it was a deep and hollow hole that could not be seen at a glance.

"How can there be such a large space? The diameter of the trunk of the World Tree is not so large!" Li Feng felt very magical.

"Master, this is the magic of the World Tree......," the little slave said with a grin, "If the inside of the World Tree is only the size of its trunk, then what's so special!

"It's amazing...... Li Feng walked a few steps unbelievingly, touched it a few more times, and found that the vision was not deceived, and the space was real.

"What should such a large space be used for?" Li Feng subconsciously asked.

"Of course there are so many uses!" the little slave happily explained, "the master will not have to worry about not having a storehouse in the future, and besides, we can live in it......"

"Can this place be lived? It's empty, how can you live?" Li Feng asked again.

"The host...... You're underestimating the World Tree!" The little slave said with a grin, "In this space, you can control the trunk of the World Tree at will, as long as you like, you can spell out any kind of room at will, it's very easy!"

"Really?" Li Feng looked surprised, "What should I do?"

"Master, look at me, for example, this raised lump, I want to stretch it ......" The little slave pulled a lump out of the tree wall in front of Li Feng - like a silk gummy, a long wooden plank was dragged out.

This is amazing! Li Feng's eyes widened.

However, that's not all.

The little slave glanced at the plank and said, "This plank is too narrow, I want a whole plank!"

As he spoke, the little slave casually widened the narrow plank, which was like dragging out a small door......

"Master, you're just that simple, have you learned?" the little slave stared at Li Feng.

"I'll try ......" Li Feng learned from the little slave's method, and sure enough, he easily got a big wooden board from the tree wall.

Then he tried to turn the plank around, and soon came up with something that looked like a pigsty with a low wooden wall......

"It's kind of interesting, so that I can easily build a house by myself! I want to build a room of my own......" Li Feng was instantly full of interest, and tried to pull out all kinds of wooden walls and began to build a house.

However, in half an hour, Li Feng successfully "enclosed" a room of about 40 square meters, and directly pinched out beds, chairs and other furniture out of wood......

"This is the real log furniture! It's a pity that this room doesn't have an external window, and it always feels breathable!" Li Feng said with some regret.

"You can open the window, and you can also get a sightseeing terrace!" the little slave explained, walking to the tree wall, reaching out and poking it, and poking it open, and then pulling it, there was a small window......

Li Feng looked out in surprise and found that it was his farm territory outside, the heavenly spirit fruit tree that emitted golden light and the falling phoenix plane tree shining with red mangs competed with each other, and the beetle snake Xiaobai was floating and wandering between the two treasure trees......
