The gambling contract was established, and Jingzhen opened his mouth to agree on the competition process with Itagaki Nobukata.

"How to verify the effect of three percent, I tried to think of a set of fighting methods, that is, using all the ore produced today in a certain pit as raw materials, I and another person are opponents, each commanding people to smelt half of the ore, and finally comparing the output. What does Suruga Mamoru think of this method? ”

After hearing this, Itagaki Nobukata nodded and said with satisfaction:

"His Royal Highness Jing Zhen is very thoughtful. This law is the fairest, there is nothing to add below, and I believe that both parties will not have any objections to the result, so let's proceed accordingly. As for the time of the gambling fight, why don't you set it for after sunrise tomorrow? Please also ask His Royal Highness Jing Zhen to list all that needs to be done immediately. ”

"In addition, I have assigned manpower to clear out the idle people near His Royal Highness Jingzhen's residence, so I can just rest in peace tonight."

"Then thank you for the kindness of Suruga Mamoru Mamoru then!"

Jingzhen didn't seem to hear the meaning of Itagaki Nobukata's point of monitoring, and thanked him safely.

"Your Highness, let me come down to be the opponent of His Highness Jingzhen!"

Seeing that Jingzhen and Itagaki Nobukata decided to gamble tomorrow in a few words, and was reprimanded by Itagaki Nobukata many times today, a tiger suke who thought he was a big loss of face finally couldn't hold it back and took the initiative to ask to compete. Jingzhen only saw his horizontal eyebrows and eyes, and his atmosphere was not smooth, and he knew that he probably wanted to defeat himself in one fell swoop, beat him as a liar, and take a good look at today's grievances.

Itagaki Nobukata suppressed a tiger help many times, and he had the intention of using it as a raft, but now seeing that he took the initiative to ask for battle, he said happily without disguise:

"Well, then it's hard for Uemon to show off his skills on behalf of his family!"

"Hoo, I will not fail in my mission!"

After everything was discussed, Itagaki Nobukata assigned a tiger to prepare for the relevant matters, and he hurriedly returned to the Rushan government affairs, and Jingzhen also returned to the dormitory under the escort (escort) of a small group of elite flags. On the way, he also happened to meet Fan Fu Huchang who returned from patrolling the city, although the latter was a little curious, but when he saw that Jingzhen had his own flag book to follow, he was not afraid of chaos, so he didn't ask much.

After returning to the dormitory, Keije 1510 recounted to the people who had been waiting for a long time about his visit to Itagaki Nobukata today. Although Crane made a few jokes on behalf of everyone, such as "troublemaker", he still understood and supported the decision made by Jingzhen, who was the backbone of the team, and encouraged him to rest and compete at a good level.

The moon sets and the sun rises, and there is nothing to say all night. The Takeda family has a big business, and Nobukata Itagaki is even more resolute. When Jingzhen and his entourage came to the playground of Chuyang Middle School, the required ore, auxiliary materials, and smelting furnaces were ready, and Itagaki Nobukata and Ichijo Tiger were also waiting here with more than 100 skilled craftsmen.

After checking whether the utensils were suitable one by one, Jingzhen finally came to the mountain of minerals that shimmered with dazzling golden light in the morning light. I saw that the ore was piled into two small hills, although it was of general size, but the one marked as "Nizi" on it was obviously mainly chaijin, and there were many gaps in it, and the actual amount was far smaller than that of the other "Takeda", which was mainly placer gold and had tighter grains. Jingzhen raised her eyes and saw that a tiger suke also happened to cast a sinister and smug smile.

Raising his eyes and seeing a sinister and smug smile cast by Tiger Suke, Jingzhen frowned and said:

"Your Highness, is there only so much that you can mine in a pit in a day? In addition, your veins are inevitably too rich, why do you only see gold but not stone? ”

Jingzhen didn't complain about the unfairness of the minerals, but asked for the poor materials that were discarded on weekdays, which was really unexpected by a tiger help, and he wondered:

"Stone, what do you mean from the barren stone that has been mined? His Royal Highness Jingzhen is not deliberately looking for happiness, the daily output of those poor materials is ten times that of rich materials, and the craftsmen have been ordered to refine them according to the method of smelting, but the poor materials of hundreds of stones are often only refined into a few grains of gold, which is completely disproportionate to the labor consumption, what is the use? ”

"His grass, my treasure. Just because Your Highness has nothing to do about this doesn't mean that there is no solution here, and please let Your Highness transport all those poor materials according to the gambling contract! ”

"Youemon, according to what His Royal Highness Jingzhen said, pull all the poor materials!" After hearing the argument between the two, Nobukata Itagaki made a judgment.

"Yes! It's just that you don't want these useless Laoshzi, just grinding them into a pulp will tire the sons and daughters half to death, His Royal Highness Jingzhen can take it. Anyway, in this pile of rich materials, it happens that the particles are fine and the weight is more sufficient, even if you give you the few gold in the scrap, you will win in the next place! ”

Jingzhen ignored a tiger suke's verbal offensive and turned to Itagaki Nobukata:

"According to the gambling agreement, I also asked Lord Suruga Mamoru to order that the poor materials will be transported and evenly distributed to His Royal Highness Ichichi."

Itagaki Nobukata tried to create a fair competition as much as possible to find out the true effect of Jingzhen's "secret technique", but he didn't expect that a tiger suke played tricks on the raw materials of both sides because of his revenge, which frustrated his intentions. However, if it was openly exposed to its fraud and reprimanded for the competition, it would hurt the face of the Takeda clan, so Jingzhen did not stop the competition, but only asked for daily scraps, which made him very relieved and decided to support it.

Therefore, he pondered for a moment, shook his head, and said:

"I also know a thing or two about what Uemon said, and the family only smelts 'rich materials' that obviously contain gold on weekdays, and for those ordinary poor materials, they are indeed directly discarded. If His Royal Highness Jingzhen really needs it, he will make up for all the poor materials to you, which can be regarded as making up for the clever 'little actions' of the right emon. ”

"This is stable, let you see the first productive forces of science and technology!" Jing Zhen said secretly.

While waiting for the poor materials to arrive, the two sides invariably began to concoct the rich materials at hand first.

In the first step, both men instructed their laborers to break up the lumps of rich material into soybean-sized pellets. In this way, the original hillock of comparable volume quickly divided the gap: the Jingzhen side was mostly large and had many gaps, and the volume was seriously shrunk several times after being broken; The Tiger Aid side is carefully selected placer gold, stacked tightly, and the volume is almost not reduced after being broken.

In the second step, the two sides begin to distinguish between the operations. According to the traditional practice, Ichijo Tiger Suke ordered people to put the particles into the stone mill while grinding and rinsing, and the mixed epiphytic rocks were ground into mud and washed away, leaving scattered gold, and finally the scattered pure gold grains were put into the mold to melt and cast into yellow and clear "Koshu gold"

On the other hand, Jingzhen is on the side. I had the experience of refining gold and silver from copper in Kyoto, but this time it was one time and two times ripe. Under the strong blowing of the helper, the particles are spread on the charcoal and sintered into a ball, and then the particles are mixed with lead blocks and put into the gold furnace for further melting, and finally the outgoing incandescent liquid is poured into the ash pit to form, and after its condensation is complete, a grain of pure gold is turned out from the bottom of the ash pit, and finally the same mold is used to cast into a piece of "Koshu gold"

At the end of the second step, the volume of Jingzhen's rich material particles is obviously small, and the amount of Koshu gold obtained in the end is comparable to that of a tiger suke.

"This, this can't be! You kid must have been a deceitful and mixed with impurities in gold! Yes, it must be the lead you just added! ”

Ichijo was knocked down by reality and couldn't accept all this, and shouted:

"As the old saying goes, 'gold is not red', this highness casts Koshu gold thick yellow hair red, the color is really old and decrepit, the weight is also right, and there is no problem with purity. Of course, the casting of His Royal Highness Torsuke is also excellent, but it is dwarfed by this Highness. ”

Fortunately, Itagaki Nobukata had already prepared and brought the leader of the Takeda clan in charge of Koshu Gold Casting, which directly affirmed the quality of Jingzhen Gold Casting and knocked out the last glimmer of hope for Tiger Suke.

When the poor materials arrived, Jingzhen repeated the above operation again, and obtained nearly ten "Koshu Gold" of the same quality, and finally won a big victory with a score of 31 to 22.
