　　 Ishikuma does not know much about the heat treatment process of steel, but he has heard of the "four fires" of the heat treatment process of steel.

　　 Annealing, normalizing, quenching and tempering are the four fires in the heat treatment process of steel.

　　 Just like when the barrel was built yesterday, when the molten steel was poured into the mold, the natural cooling was normalizing. The effect is similar to annealing. Anyway, it is a natural cooling method.

　　Quenching is the rapid cooling of the workpiece by immersing it in cold water or cold oil at a high temperature. Quenching will make the steel making the workpiece hard and brittle, much harder than the steel under natural cooling.

　　Of course, quenching will make the steel brittle, so it is best to perform tempering again. It is to heat the quenched workpiece to about 700 degrees again for a long period of heat preservation, and then cool it naturally. The hardness of the workpiece obtained in this way is increased, but the toughness will also increase a lot.

　　 Ishikuma knows a little bit about the general theory of heat treatment just now, but he really doesn’t know how to perform heat treatment. Even if it is the most common quenching process, he has seen it from movies or TV, and he has never personally operated it himself.

　　 As for the hardness of the tools made by Lieutenant Ferguson, Ishikuma is not worried about this. Because the hardness of the hardened workpiece is much greater than that of the original steel. If this tool is too fragile, give him a temper at that time, and let this guy figure it out for himself.

　　 But looking at the look of Lieutenant Ferguson, he obviously knew what quenching was all about.

　　 Of course, it’s far from enough to know what the quenching process is. Especially the barrel that was built yesterday is far from enough for Lieutenant Ferguson to experiment.

　　 So, as long as this guy is interested in the new gun, he will definitely learn more knowledge to serve his new gun. For example, how to make steel, how to make molds, how to make gun barrels...

　　 These things are complementary to each other. If there are few of them, new guns cannot be produced.

　　 Only if Lieutenant Ferguson is interested in more and more things, can he stay in the Gaoshu tribe for a while.

　　 Ishikuma has never thought of keeping Lieutenant Ferguson by his side forever, and Ishikuma can't do that even if he asks himself. Patrick Ferguson, who I learned from the history books, was a soldier who was very loyal to the British Empire. If the British Empire is okay, Lieutenant Ferguson may stay in the Gaoshu tribe for a while, even if he is kept until the start of the independent war, Shi Xiong is confident that he has this certainty.

　　 But once the War of Independence starts, as a loyal British officer, no matter how good the conditions are, I am afraid that Lieutenant Ferguson will not be able to retain Lieutenant Ferguson. He will definitely leave everything here without hesitation and walk towards the battlefield with a gun, even if he is facing death, he will still not stop.

　　 In this regard, Shi Xiong had already thought of this when he left Lieutenant Ferguson at the beginning.

　　 However, between now and the outbreak of the War of Independence, there are still eleven years, and nothing major happened in Britain during this time. Therefore, if Lieutenant Ferguson can stay here to develop new weapons for himself, then the weapon system of the Gaoshu tribe will inevitably make a qualitative leap.

　　 Even if Lieutenant Ferguson returns to the British army and brings these new technologies to the UK, the Gaoshu tribe will still take the lead.

And Shixiong did not intend to let Ensign Ferguson work alone. Whether it is a rabbit mouth or a hard bone, he has shown a strong interest in firearms. By then, the two little guys will be completely arranged by Ensign Ferguson's side, and they will learn while working as assistants. Lieutenant Ferguson has something about firearms.

　　 Shixiong doesn't believe in the cleverness of the bunny mouth and hard bones, they can't hollow out Ensign Ferguson in ten years!

　　 So from this day on, the bunny mouth and hard bones became the two tails beside Lieutenant Ferguson. For these two little guys, Lieutenant Ferguson also liked it, after all, the unique simplicity of the Indians was enough to make Lieutenant Ferguson feel different care.

　　 Even Ferguson often teaches bunny mouths and hard bones to speak English, and Shi Xiong is a little surprised by the talents shown by these two guys in language.

　　 For Ferguson to build barrels to experiment with different guns, a lot of steel must be needed.

　　 For this reason, Shi Xiong even did not hesitate to mobilize the whole clan once again to excavate iron ore, limestone and coal. The excavation operation benefited from the large-scale use of iron tools and the use of horse-drawn carriages. In just a few days, more than 200 people dug up a large amount of iron ore, limestone and coal.

　　 Ishikuma is also preparing to start coking alone.

　　 The last time coking had to take care of the firing of refractory bricks, Shixiong used the simplest way to make coking, but the coking effect was not ideal.

　　 In order to increase the success rate of coking as much as possible this time, Shixiong decided to adopt the earth kiln coking method.

This earth kiln coking is the coking method that Shixiong wanted to use but did not use last time. The yield of coking in earth kilns is much higher than that of the big pit coking method used by Shixiong last time. Get more coke in one go.

As usual, the whole clan is mobilized~www.readwn.com~. Under the current situation, Shixiong doesn’t even need to speak with Lei Lei. He only needs to say “I want to open the furnace for steelmaking again”, then almost all the people who can move The clansmen will come to help.

　　 Although the quality of the steel produced from the last time the furnace was opened was substandard, 90% of the steel was produced into pig iron, and the quantity was only about three tons, but this still made the whole people happy for a long time.

In the past, the clansmen of the clan who wanted to use iron tools had to exchange the precious fur with Vasichu’s trading team, but now under the command of the guardian, they can make steel by themselves. Who doesn’t want the guardian How many times do the adults open the furnace to make more steel?

　　 Anyway, iron ore, limestone, and coal do not cost money. You only need to spend some effort to make steel out of these things. Who wouldn't want to do it?

　　 The tribesmen in the tribe are not fools. After refining steel, making salt, and using new farm tools, they have fully understood the hard work of Lord Guardian. He is sincere for the good of the tribe!

Therefore, it is not an exaggeration to say that even if Li Lei stepped up and ordered the clansmen not to obey Shixiong’s orders, it is estimated that at least nine of the ten clansmen would not obey Li Lei’s orders. It's the little baby who can't understand Li Lei's command.

　　 Had it not been for the Kaburu priest of Hongyun who had not spoken, the tribe would want Stone Bear to replace Li Lei as the new patriarch!

　　 Don't doubt, most of the people think so now.

　　 In this kind of thing, whether it is ancient or modern, whether it is Chinese or Western, it is the same.

　　 Who can make our life better, we will follow whoever, we will support whoever!
