Cultivation of Immortals Begins with Drilling Wood To Make Fire

  Chapter 487 [Tinning on the mountain]

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

The short-term coolness after the rain also disappeared with the rainbow in the sky. The sun was blazing, and the rain that had just fallen turned into water vapor after this transpiration, so the surrounding became stuffy and hot, only a little better than before the rain. .

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

  Because we ate something in Huqiao Town, even though it was just evening, Fang Chang didn't plan to make dinner anymore.

  He returned to the warehouse and threw all the sundries that had not been sold before into the warehouse. Then he walked to the big rock on the edge of the cliff, changed a different posture from the usual morning, facing west, admiring the sunset after the rain.

  The sky and clouds washed by the gusts and rainstorms are extremely clear, transparent and pleasant.

  The setting sun gilded the scattered clouds towards the west, which turned the sky in the gaps in the clouds into blue. As the sun continued to set, the clouds began to appear large black, which is where the sun can no longer reach.

  ………

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

  Today he is not going to set up a stall, but toss around in this work shed.

  There is a large and flat anvil in the workshop at the foot of the mountain, and a complete set of tools are hung on the wall. There are abundant materials and semi-finished products in the warehouse next to it, and there is a room where many of his previous works are piled up. But he didn't come here for a few days, and there was already some dust inside. Fang Chang picked up the broom and dustpan and cleaned it before turning and walking into the warehouse next to him.

  The shed has been completely renewed.

  He rummaged through the warehouse, found a glass bottle with a relatively flat outer wall, and put it aside for later use. There were also large and small tin ingots and tin plates in the warehouse. Fang Chang found a small one and carried it into the shed.

  He took down the sledgehammer from the wall, put the tin plate on the anvil, swung the hammer and hit it upwards. The huge anvil did not move, but the tin plate was gradually extended under the constant knocking, turning into a thin sheet, and then into tin foil.

Making tin foil saves material, and Fang Chang didn’t need so much tin at all, so he cut off most of the tin foil and threw it back into the warehouse, and then rolled up most of the tin foil, leaving the rest on the plank for making on the workbench.

  Fang Chang is going to make a Leiden bottle.

   Of course, it could be called something else these days, and that doesn't matter.

  The structure of this bottle is very simple. It is a glass bottle with a layer of tin foil on the inner and outer walls. A metal rod with a small ball at the end and a chain are fixed on the bottle stopper. The chain contacts the tin foil on the inner wall.

  You can choose dry wood for the bottle stopper, but it is not convenient to use copper and iron for the metal rod, so Fang Chang chose silver. There are many of this metal in the warehouse, and it is very malleable.

   Another beating, and the silver rod became an ideal shape.

The wooden stopper is rather troublesome. Fortunately, Fang Chang 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. The silver rod inside the cork is also made in the same way-anyway, the square is long and strong.

  Looking at the completed Leiden bottle, Fang Chang took off the wine gourd from his waist.

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

  At that time, he caught this bolt of lightning just because of his whim. Fang Chang didn't think about what to do with the lightning he caught, anyway, it's not suitable for braised.

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

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

  Several scattered electrical traces escaped from the top of the bottle, and were about to drill into the ground. Fang Chang's hands were quick, and he stretched out his hand to grab the scattered lightning, and it turned into the bright lightning before again.

  Fang Chang secretly sighed and shook his head.

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

   After thinking about it, he had no choice but to break off a small piece from the ball of lightning and put it back into the Layton bottle.

  The bottle held up this time.

   "Huh—it's still a technical job." After Fang Chang stopped, he put the lightning in his hand back into the bottle, and then picked up the Leiden bottle in front of him to watch.

  Both the texture of the bottle itself and the tin foil on it are very rough, but it works normally, and Fang Chang likes it very much.

  There is a pen, ink, paper and inkstone on the workbench. Fang Chang took out two pieces of paper and recorded the process of this experiment.

   As for the bottle itself, he didn't think about what it could be used for.

  So Fang Chang took a glass basin as a cover, and gently covered it on the Leiden bottle to prevent other creatures except himself from accidentally touching it. Then this bottle was stuffed into the warehouse, and its treatment was good. A bottle alone occupied a storage grid.

   By the time all the work was done, it was already noon.

  The ball of lightning continued to lie obediently in the gourd, maybe Fang Chang would forget about it, or drink it as a new taste of wine.

  Clean up the workbench, go outside, and fetch two pieces of wood.

  The wood is very ordinary, just common elms in the mountains. After drying, they are piled in the shed, and the lower part is framed with stones to prevent it from being burned.

  Fang Chang once made woodworking lathes.

  Different from lathes that use steel as raw material, woodworking lathes have extremely low technical content, especially after using manpower as a power source.

   It didn't take much time to build it, because its structure is very simple.

   There is no lead screw, no bearings and belts, and no feed box and tool holder. The entire woodworking lathe has only one shaft and a wooden bow as a power source. The bowstring is made of the toughest rattan bark, braided rope.

   Fang Chang gently clamped a piece of wood that had been cut between the two pointed cones, and gently pulled the bowstring in his hand.

  Then the shaft below was driven by the bowstring and quickly rotated back and forth. He drew a carving knife from the side, and gently approached the wood block, so the sawdust flew, and the wood block quickly took shape.

  In fact, when a few pieces of wood were broken into planks, woodworking machine tools were already used.

  Although the square length is absolutely sure, using a saw can easily and standardly break the wood into planks and blocks, but using more advanced tools can make it easier and less labor-intensive.

  The part with the highest technical content on the sawing machine is the large saw blade made of bronze. At present, Fang Chang is temporarily unable to make such a saw blade with steel. The power source of the sawing machine does not come from the bow and strings, but from a big crank below.

   Thank you for the reward from the ignorant chef.
