The manufacturing of copper tripods is the crystallization of the wisdom of the ancients. It started with the pottery tripods made in ancient times, to the era when Huangdi collected copper from Shouyang Mountain, and then to the fact that the tripod became a national weapon, in the thousands of years of history of China, the meaning of the tripods represented was not only its own function. In Liu Yi's view, the idea of ​​making copper tripods at this time was not considered outdated in modern society.

The current method of making copper tripods is the pouring method. First, make a high-temperature-resistant model, then melt the copper into copper juice, and then pour it into the prepared mold.

This is not as simple as melting copper into liquid and pouring it into it. The melting point of copper is about one thousand degrees, but to become a liquid completely, it is obviously much higher than this temperature. Most people can't bear the heat even when they get close to it, let alone pouring it into it with a container.

According to the information obtained by Liu Yi checking ancient books, the most difficult thing to make this large copper tripod is not to shape it, but how to water the copper juice into the model, and there are no bubbles in the middle. In order to overcome these difficulties and bring wisdom to the extreme, our ancestors would create a complete set of mechanisms specifically used for watering. The production of these mechanisms is much more complicated than simply shaping the copper tripod. Even if there is a problem in one link, it may lead to the failure of casting the entire copper tripod.

Liu Yi's most frequently designed this mechanism during this period. The distance from the model should not be too far away, otherwise the copper juice would solidify during the flow. The materials used in the mechanism should have sufficient heat insulation to keep the temperature of the copper juice from dissipating too quickly.

The mechanism itself must have a certain degree of airtightness, otherwise the copper juice leaks out and it is likely to directly damage the mechanism. Moreover, there will definitely be some loss during the copper juice flow, so this must be considered before smelting.

If it weren't for the power of the five elements of the building itself to strengthen the furnace temperature, Liu Yi would not have been able to guarantee that he could make the three-meter-high copper tripod at one time, and in terms of time, he would not have given him a second chance to cast a tripod.

When Liu Bei arrived in Hanzhong, it was when Liu Yi made all preparations and began to pour copper juice to shape the copper tripod.

"Lord, the Marquis of Ting has given him the order that no one can come in!" Guan Ping saw Liu Bei coming, and hurried forward and bowed to Liu Bei.

"Oh?" Liu Bei looked at Guan Ping unexpectedly and said, "I heard from Wen Chang that Bo Yuan had been in this for seven days and had not yet made it?"

He wanted to see the altar, but when he arrived in Hanzhong, Liu Yi happened to be ready and started the last process. The entire altar was blocked by Liu Yi for a mile of one mile built by Liu Yi.

"It hasn't come out yet." Guan Ping shook his head: "According to what Tinghou said, the shed must be absolutely sealed, with only a few small windows, and daily meals are delivered from these places."

"Don't that person be suffocated to death?" Zhang Fei glared in surprise.

"This..." Guan Ping didn't know how to explain: "It should be fine. Today's morning edible plates were sent out. According to what Tinghou said before blocking this place, it should be the time to achieve success in these two days."

The altar has been made long ago. Now what Liu Yi makes is the big tripod for sacrifice to heaven. How big the nine tripods cast by Dayu in the past is no longer verified, but the bronze tripod that Liu Yi wants to cast is probably the best in the world.

The whole shed looked like an egg pressed upside down on the ground. Even if it was not the first time Liu Bei, Guan Yu, Zhang Fei and others were amazed.

The three brothers waited for a long time without seeing any movement inside, so they prepared to go back to Nanzheng. After all, Liu Bei was going to prepare for the upcoming sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrificial sacrific

It's a pity that I'm not going to meet for the time being.

Time passed by bit by bit. As the Double Ninth Festival was about to come, the huge shed that wrapped the entire altar was never demolished. The discount made Liu Bei feel a little worried, is Liu Yi okay?

"Lord, don't worry, lord, Bo Yuan has always been responsible for his work. This time, in order to congratulate the lord and be named king, Bo Yuan said that he would make a first cauldron in the world to congratulate the lord and be named king!" Zhuge Liang smiled and comforted. In fact, he was also a little worried.

"In fact, there is no need to worry so much." Liu Bei shook his head and said. Now the overall situation has been decided, and what is missing is just a ritual. In fact, since Qin unified the world, although this kind of sacrifice is still important, the sense of ritual has gradually surpassed the actual meaning. Although the princes attach importance to it, in fact, the level of attention cannot be compared with before the pre-Qin period.

When the overall situation is decided, according to Liu Bei's intention, it is enough to be meaningful. There is no need to be too extravagant. After hearing about the money spent on the altar casting, he felt a little distressed.

Zhuge Liang smiled without saying a word.

On the eighth day of the September 19th, just the day before the Double Ninth Festival, news came from the altar that the huge shed had begun to be demolished and the ceremony of the king's title could be held as scheduled.

The whole of Nanzheng suddenly became busy. Wei Yan mobilized troops around to maintain order. This time, in order to confirm the legitimacy of Liu Bei's king, people were allowed to watch the people on the periphery, not to mention that many scholars from all over the world came to watch the ceremony. From this point of view, it was not wrong for Liu Yi to make the sacrifice more glorious. At this time, it was not just a sacrifice, but also a meaning of demonstrating national strength.

However, at this time, Liu Bei obviously could no longer see it in person.

On the ninth day of the ninth month, on the Double Ninth Day, Liu Bei led all the officials of Jingshu to the altar, and accompanied them were Kan Ze, the envoy of Jiangdong and the envoys who accompanied them.

When he arrived at the altar, even though Liu Bei was prepared, he was still shocked by the altar in front of him.

The altar is about three feet high, but it does not look abrupt. It is divided into three layers. On the altar, nine red dragons are vivid, with the nine dragons facing the sky, and the dragon heads facing the center of the altar.

At the top of the altar is a prototype platform about ten feet, but inside is a square copper tripod, three feet high and ten feet wide. The altar, which was not originally abrupt, is a strange peak protruding here, giving people a visual impact. The copper tripod on the altar makes people feel a visual misalignment with Tianqi. The closer they are, the stronger the feeling.

Especially today's weather is not good, the sky is gloomy, and the whole sky seems to be much lower. The giant cauldron is under it, visually, as if it has dragged the sky.

"How might it be!" Looking at the giant tripod in front of him, Liu Bei couldn't help but exclaim.

Liu Yi walked down with a tired look on his face, bowed to Liu Bei and said, "Lord, fortunately I have not been humiliated!"

Looking at Liu Yi's tired look, Liu Bei hurriedly stepped forward and helped him, "Boyuan doesn't have to do this, the time is right."

It is not convenient to say too much at this time. After a few simple instructions, Liu Bei asked Liu Yi to step down first and prepare for this matter before rewarding Liu Yi.

"Boom~" There was lightning passing by in the sky, which was not a good sign. However, since you chose the date on this day, it is impossible to make any changes at this time. After all, this kind of thing is always time to pinch it.

When Liu Yi turned around, he looked at Liu Yi calmly, tacitly.

I silently returned to the train, and the sacrifice officially began at this time. The officials who were specifically responsible for this began to perform the sacrifice step by step.

To worship ancestors, slaughter three animals is the best, then worship the heaven and earth, and finally walk to the second floor of the altar and read the sacrificial text in the bronze tripod. The general meaning is to prove the rationality of being the king.

Liu Yi looked at the altar and was a little incredible. At the moment when the bronze tripod was completed, it seemed that it was integrated with the altar and no new attributes appeared. Liu Yi was a little puzzled. This was the first time in his career as a craftsman, and he had no experience, which wasted so much of his new learning.

"Boom~"

Just as Liu Bei finished reading the sacrificial text, a thunder suddenly descended and landed fiercely on the copper tripod’s IQ. The strong light flashed in that moment and the thunder that seemed to explode in his ears made everyone fall into a brief state of blindness and deafness at that moment, and the thunder and lightning fell accurately on the copper tripod.

A noise sounded around, and the people farther away began to talk, and the officials were also a little worried. Could it be that God believed that the Han Dynasty had been exhausted and opposed Liu Bei's claim to be king?

Zhuge Liang also looked at Liu Yi with concern. He calculated that there would be a thunderstorm on this day, but he did not expect that this scene would happen. If it was not handled properly, Liu Bei's prestige would probably be greatly lost.

Liu Yi didn't say anything, but just looked at the bronze tripod on the altar seriously. It took her a lot of thought for this scene.

"Look!" The civil and military officials who were closer suddenly pointed at the bronze tripod and screamed in surprise.

Many people were subconsciously surfing around, searching for possible changes. Soon someone discovered that the bronze tripod above the altar had cracks and was expanding. The far might not be able to see clearly, but some of them were seen very clearly, but there were only a faint red color under the blue skin.

Immediately afterwards, the bronze cauldron on the surface gradually fell off and fell into everyone's eyes. The bronze cauldron was not destroyed by lightning as imagined. Instead, after the copper cauldron gradually peeled off, a red copper cauldron appeared, and a red dragon carved on the body of the cauldron looked lifelike.

In the most eye-catching place of the bronze tripod, five big characters appear: The Han Dynasty became popular here.

The original doubts gradually weakened after these five big words appeared. Liu Yi and Zhuge Liang looked at each other and bowed to Liu Bei first: "God bless the great man!"

"God blesses the great man!"

Others also gradually reacted and fell to the ground excitedly. No matter how many of the scholars present believed, at least, at this moment, most people believed that Liu Bei would become the lord of Zhongxing, and their attitude towards Liu Bei was more pious than before. At this point, Liu Bei's title of King Hanzhong was completely established...
