Based on his previous inferences, glass should be able to be made by firing sand in a furnace.
Because what Li Wenxi had been selling him were smelted iron blocks, his furnace had been idle for a long time.
After getting down from the tree house, Xu Xin filled a wooden barrel with sand and gravel at the lakeside, then came to the furnace on the second floor of the tree house, added a few pieces of wood as firewood, and poured the sand and gravel into the furnace.
The melting time for a single piece of glass was very short; in just a minute, Xu Xin had produced a thick piece of glass. The furnace continued to work. Judging from the melting time, the bucket of sand he brought should be enough to melt twelve pieces of glass.
He'd just been worried about the glass being too weak, but this explanation put his mind at ease. He hadn't expected green-grade glass to be as strong as the treehouse walls. Was the glass too strong, or were the treehouse walls lacking in defense?
However, there is no need to worry too much even if it is not strong enough. After all, the walls of the tree house are wrapped in dense and thick banyan leaves. What needs to be protected is the exposed trunk, and the trunk has long been covered with a layer of armor.
Letting the furnace continue smelting, he returned to the top floor of the fourth floor and chose to make glass windows on the watch.
Following the familiar process, Xu Xin directly chose the slanted ceiling.
With a "click", a 1*1 ceiling was replaced by thick glass. Through the glass, Xu Xin could see the transparent banyan leaves outside and the sky full of stars.
"It's done!"
This glass window is a fixed window embedded directly into the ceiling and cannot be opened or closed. This is exactly what Xu Xin wants. He just wants to make the top ceiling look like a glass greenhouse, and it would be best if it is fixed and cannot be opened.
After moving the three flower pots from the third floor up, Xu Xin placed the strawberry pot by the window and the two new flower pots in the middle and highest position. He bought a few seeds from the trading platform, planted two red berry bushes in one of the pots and an orange tree in the other.
These two resources are what Xu Xin uses the most now. Basically, they have to be consumed at night during the activity, especially the large red berries. He ate at least a dozen of them in the dungeon. The consumption rate is very fast, so he must have his own source.
Both redberry bushes and orange trees bear fruit in ten days, and in large pots, it only takes six days.
I don’t know if the blue-level red berry bush outside has borne fruit again.
Xu Xin returned to the lake and filled several buckets of sand, bringing them back to the tree house. He poured it all into the furnace and assembled the melted glass onto the top floor ceiling. After nearly an hour of work, the top floor ceiling was finally half-transparent.
Standing on this floor and looking up at the sky, you can see twinkling stars and a bright galaxy, which is extremely beautiful.
"Perfect! This is the real starry sky ceiling. I want to live right here on the top floor!"
This floor felt too empty with only three large flower pots, so Xu Xin bought fifty ordinary green-grade flower pots from the points mall. These flower pots could hold green-grade soil and shorten the growth time.
An ordinary flower pot only costs 5 points, which is equivalent to the points of a green-level fertilizer. Because Xu Xin has a 30% discount, only 3.5 points are needed. Fifty ordinary flower pots only require 175 points.
Xu Xin earned a lot of points in the dungeon. The points from the mutant plants killed by the cheetah were also counted towards him. Even after buying two large blue-level flower pots, he still had more than 1,500 points. He was rich and didn't feel sorry at all.
He took the Silver King downstairs and ran to a place far away from the tree house. He dug fifty portions of green-level soil and brought them back to the tree house, filling them into the fifty flower pots.
He wants to turn the entire top floor into a plantation.
He has been thinking about a question: will the heavy rain season cause flood disasters? If the flood really comes, how many plant resources in the outside world can survive the flood?
Xu Xin doesn't want to rely on the weather for his livelihood. If he builds this plantation, he will be able to be self-sufficient even if the external resources are destroyed by floods after the rainy season!
