 Li Zhenhua was rummaging around in the house. He remembered that he had put away all the things he would need before leaving for school.
 He quickly found several barrels of sealed liquid. He could see through the plastic barrels that the liquid inside flowed very slowly when he moved it.
 Li Zhenhua took out a bucket, opened the lid and looked inside.
 The bucket was filled with a black viscous liquid. Li Zhenhua checked the contents of the bucket.
 After finding that there was no problem, he nodded with satisfaction and walked out of the room carrying two buckets of liquid.
 Returning to the stove, there is a rectangular iron sink next to the stove.
 There was nothing inside at this time. Li Zhenhua opened a bucket and poured it into the sink.
 Just when Li Zhenhua was about to pour the second bucket, his analytical eyes gave another hint.
 I saw a line of prompts appear in his sight:
 ‘Diesel and engine oil mixture can be used as steel quenching coolant.
 The current ratio between the two is not the best, please continue to add engine oil to it. ’
 This reminder made him feel that having an analytical eye would be of great benefit.
 For such a problem of quenching coolant, these eyes can give the best ratio.
 Li Zhenhua returned to the room and took out a 2L red bucket again, which contained engine oil.
 This is the waste engine oil that Li Zhenhua asked for from the car repair shop in the town.
 It was also because there was no place to dispose of the waste engine oil that Li Zhenhua could take it away.
 If this were left until now, there would be no place to dispose of this waste oil.
 Returning to the sink again, Li Zhenhua unscrewed the lid of the small bucket.
 Then he found the waste engine oil inside, and his eyes gave hints from time to time.
 'Oil difference: 1200ml, 800ml...100ml, 40ml, 1ml.
 There is too much engine oil, please add diesel; current diesel difference: 2ml. ’
 It actually fell too hard, which also resulted in missing the optimal ratio.
 I added a little bit more diesel to it, saving more diesel.
 Finally, in Li Zhenhua's hands, the quenching coolant was adjusted to the optimal ratio.
 The quenching items were ready, and now only the actual operation was left. Li Zhenhua returned to the stove and took out the knife blank.
 Looking at the prompts given by the eyes, the temperature of the knife blank is slightly high at this time.
 Li Zhenhua could only stand there holding the knife blank and wait for the temperature to drop, and he was always ready to insert the knife blank into the quenching coolant.
 When the temperature finally dropped to the optimal temperature, Li Zhenhua inserted the coolant directly into the knife blank without any hesitation.
 I saw that the coolant in the water tank caught fire directly. Along with the flames, there was also the smell of burning oil in the air.
 ‘Please take out the knife blank and count down ten seconds, 3, 2, 1. ’
 Li Zhenhua immediately took out the knife blank. At this time, the hardened knife blank did not look very good.
 The surface of the knife blank was black and extremely ugly.
 Li Zhenhua took the knife blank in his hand and observed it carefully. At this moment, words appeared next to the knife blank.
 "Watermelon knife (semi-finished product),
 Length: 430mm, Width: 45mm,
 Total weight: 750g, hardness: 62,
 Toughness: Tempering has not been completed. This data is incomplete and needs to be tempered. "
 Li Zhenhua didn't expect that he just wanted to test another of his loaded functions.
 But since he made this watermelon knife, the subsequent development has been increasingly deviating from his expectations.
 If this watermelon knife is really completed according to the instructions of the Analytical Eye.
 Let alone killing a watermelon, even killing someone is a piece of cake. Maybe this watermelon knife is of better quality than the other small daggers sold in the market.
 Li Zhenhua actually wanted to know what he would end up doing with this watermelon knife.
 So Li Zhenhua planned to strictly follow the prompts of the Analytical Eye.
 ‘Please prepare the tempering solution next, raw materials: diesel, engine oil. ’
 Li Zhenhua strictly followed the instructions and prepared the tempering solution.
 Li Zhenhua, a blacksmith born in his family, certainly knew how to temper the fire. He took out a thin rectangular bucket and poured the solution into it.
 Then he squatted the bucket on top of the stove, and Li Zhenhua carefully controlled the fire.
 Until the temperature of the solution is heated close to the ignition point.
 Li Zhenhua maintained the temperature and fixed the knife blank to the solution barrel with iron wire.
 Then there was a long two-hour wait. The knife blank was placed in the solution and maintained at 220 degrees Celsius for more than two hours.
 Li Zhenhua finally took him off the stove.
 The next step is to continue waiting for the knife blank to slowly cool down in the solution.
 When the knife blank drops to normal temperature, the tempering process is completed.
 Quenching gives the knife blank its hardness, and tempering gives it its toughness. A watermelon knife is made.
 Let Li Zhenhua make it directly according to the weapon level.
 The sky darkened while Li Zhenhua was keeping the watermelon knife warm, and Li Zhenhua had no intention of keeping watch.
 Instead, leave it there to cool down naturally. Father Sun has gone down the mountain, and it's time for Li Zhenhua to eat again, but for him, this day's experience is simply amazing.
 He only sold a sickle, but actually sold himself a golden finger.
 Li Zhenhua picked up a large piece of noodles with chopsticks and put it into his mouth.
 "It seems that my life is destined to be a blacksmith. If I don't become a blacksmith, I feel that this golden finger will leave me immediately."
 After eating, Li Zhenhua walked to the stove and looked at the knife blank in the tempering solution.
 The dialog box in the eye shows that the temperature of the knife blank is 43°C.
 Seeing this temperature, Li Zhenhua knew that he could actually fish it out of the solution.
 Put on your gloves, hold the wire hanging on the side of the bucket, and fish out the knife from the bucket.
 I saw the mixed oil solution all over the blade. I put the knife base on a rag that had been prepared long ago, and used the cloth to wipe off the solution on the knife base.
 The color of the knife blank appeared in front of Li Zhenhua's eyes. The color of the knife blank was still silver-gray and a little black.
 Li Zhenhua looked at the hint in his eyes.
 "Watermelon knife (3/4 finished product),
 Length: 430mm, Width: 45mm,
 Total weight: 750g, hardness: 62,
 Toughness: good (this value is more complex and the specific value is not yet quantified). "
 The knife blank has been forged at this time, and the next step is to cut the V and edge the knife blank.
 With the help of machines, these two procedures are already very trouble-free for blacksmiths.
 However, it is still a bit difficult to do these two processes well enough to blow out and break hair.
 Li Zhenhua came to the table next to the anvil and placed the knife blank on it.
 Originally, he wanted to use a caliper to find the center of the blade, draw the line, and then get the belt sander to open the V.
 But once the analytical eye came into play.
 Li Zhenhua no longer needed to draw the line. He walked to the belt sander and clamped the knife blank on the clamp.
 Open the machine by hand and the belt sander rotates. Li Zhenhua holds the clamp with his hand and sends the knife blank to the belt sander.
 When the blade blank comes into contact with the belt sander, the friction between the belt sander and the blade blank generates many iron sparks.
 The blade gradually formed a V-shape in Li Zhenhua's hand and became more and more presentable.
 When the final eye prompt appears, the high-waist flat grinding is completed, and the next step is to manually sharpen the edge twice.
 After completing this step, the entire watermelon knife is no longer the same color as before. When the V is turned on, the belt sander has already ground out the color of the steel.
 Now it has turned half into bright silver, and as long as the remaining bit is not opened, it is still the previous color.
 Li Zhenhua took the knife blank to a corner of the yard, where there was a long bench.
 There is a millstone set on the bench, which is said to be older than him.
 Li Zhenhua sat astride the bench, took the knife and started sharpening it bit by bit.
