When Fang Chang walked to Xianqi Cliff, the rainbow in the sky had already dissipated.

The brief coolness after the rain also disappeared with the rainbow in the sky. The sun was bright. After the steeping, the rainwater that had just dropped suddenly turned into water vapor, so the surroundings became stuffy and hot, only a little better than before the rain.

Fortunately, the Xianqi Cliff is still cool due to its high terrain.

Since I ate in Huqiao Town, although it was just evening, Fang Chang was not going to make dinner again.

He returned to the warehouse and threw all the debris that had not been sold before into the warehouse. Then he walked to the big rock by the cliff, changed into a different position than usual in the morning, heading west to enjoy the sunset after the rain.

The sky and clouds washed by the sudden wind and heavy rain are extremely clear and transparent.

The sunset put the scattered clouds to the west with gold edges, which turned the sky inside the gap of the clouds into green. As the sun continued to set, the clouds began to appear in large areas of black, which was a place where the sun could no longer be shined by the sunlight.

……………………

After having a simple breakfast, Fang Chang walked to the shed.

Today he was going to not set up a stall, but tossed around in this shed.

There are large and flat anvils in the shed at the foot of the mountain, and a complete set of tools are hung on the wall. The warehouse next to it contains rich materials and semi-finished products. There are also a room full of his previous works. But I haven't come much for a few days, and some dust has fallen inside. Fang Chang picked up a broom and dustpan to clean it up before turning around and walking into the warehouse next to him.

The shed has become a brand new look.

He searched in the warehouse and found a glass bottle with a flat outer wall and placed it aside for use. There were also large and small tin ingots and tin plates in the warehouse. Fang Chang found a small piece and walked into the shed with him.

He took off the sledgehammer from the wall, placed the tin plate on the anvil, swung the hammer and knocked it upwards. The huge anvil was still motionless, but the tin plate gradually expanded and turned into thin sheets and then into tin foil.

Making tin foil is very material-free, and it is impossible to use so much tin at all. So he cut most of the tin sheets and threw them back into the warehouse. Then he rolled up most of the tin foil, leaving the rest on the workbench made of thick wooden boards.

Fang Chang was preparing to make a Leiden bottle.

Of course, it can be called something else now, and that doesn't matter.

The structure of this bottle is very simple. A glass bottle has a layer of tin foil on each inner and outer walls. The metal rod with small balls at the end is fixed to the bottle plug, and the chain and the tin foil on the inner wall are in contact.

Just choose dry wood for bottle plugs, but the metal rod is not convenient to use copper and iron, so you choose silver for square length. There are many such metals in the warehouse and have good ductility.

Another blow, the silver stick also became an ideal shape.

The plug is a bit troublesome. Fortunately, Fangchang chose a kind of cork, which does not need to be exactly the same as the bottle mouth, but only needs to be slightly larger. At this time, you can use force to firmly clamp the plug at the mouth of the glass bottle, and the silver rod inserted into the plug is also done in the same way - anyway, Fangchang has a lot of strength.

After looking at the prepared Leiden bottle, Fang Chang took off the wine gourd around his waist.

He took out a bright and flashing lightning from it, which was the lightning he caught on the road when he came back yesterday.

At that time, he was just a pleasure to catch this lightning. Fang Chang didn't think about what to do with the lightning he caught. Anyway, it was inappropriate to use it to brais.

Fang Chang put the gourd on the table, picked up the Leiden bottle with his left hand, and slapped the lightning in with his right hand. After the lightning touched the small ball of the silver rod, he immediately slipped into the bottle along the silver rod.

Then the glass bottle with two layers of tin foil inside and outside was broken through by lightning.

Several scattered electric marks escaped from the bottle and were about to drill into the ground. Fang Chang's hand quickly and quickly saw the scattered lightning, and reached out and grabbed the lightning again in his hand, and then turned into the bright lightning that had been before.

Fang Chang sighed secretly and shook his head.

The voltage of lightning is much higher than the breakdown voltage of glass, so this Leiden bottle cannot store this ball of lightning.

After thinking about it, he had to break a small piece off the ball of light and put it back into the Leiden bottle.

This time the bottle held it back.

"Huh-it's actually a technical job." Fang Chang stopped and stuffed the lightning in his hand back into the bottle, then picked up the Leiden bottle in front of him to watch.

The bottle is very rough, regardless of its texture or the tin foil on it, but it works very normally and I like it very much.

There are pen, ink, paper and inkstone on the workbench. Two sheets of paper were drawn in a long time, and the process of this experiment was recorded casually.

As for the bottle itself, he didn't think about what to do.

So Fang Chang took a glass basin as a cover and gently covered it on the Leiden bottle to prevent other creatures from touching it by mistake. Then the bottle was stuffed into the warehouse. Its treatment was very good. One bottle occupied a storage lattice alone.

It was already noon when I finished all this.

The lightning continued to lie honestly in the gourd, perhaps Fang Chang would forget it or drink it as a new flavor of wine.

Clean the workbench case, walked outside the house, and took two pieces of wood.

The wood is very ordinary, but it is just a common elm tree in the mountains. After drying, it is piled in the shed, and the lower part is set up with stones to prevent it from being stewed.

Fang Chang once made woodworking lathes.

Unlike lathes made of steel, woodworking lathes have extremely low technical content, especially after using manpower as power source.

It took a long time to create it.

Gently clamp a piece of cut wood into two pointed cones, and gently pull the bowstring in your hand. So the shaft below is driven by the bowstring and rotates quickly back and forth.

In fact, when I just broke a few pieces of wood into wooden boards, I had already used a woodworking machine tool.

Although the square length is absolutely certain, and using a saw can easily and standardly break wood into wooden boards and blocks, it doesn’t take much time to build it with a human square length.
