The manufacture of copper tripod is the crystallization of the wisdom of the ancients, starting from the pottery tripod made in ancient times, to the copper tripod era opened by the Yellow Emperor collecting the copper of Shouyang Mountain, and then to the tripod becoming the country's heavy weapon, tripod in the history of China for thousands of years, the meaning it represents is not only its own function, in Liu Yi's view, to this time the concept of manufacturing copper tripod is to put it in modern society, and it is not outdated.

At present, the way to make copper tripods is the pouring method, first make a high-temperature resistant model, and then melt the copper into copper juice, and then pour it into the mold.

This is not as simple as you melt copper into a liquid and pour it in, the melting point of copper is about 1,000 degrees, but to completely become a liquid, it is obviously much higher than this temperature, ordinary people are close, the heat can not withstand it, let alone take the container and pour it inside.

According to Liu Yi's information obtained from reading ancient books, the most rare thing to make this kind of large copper tripod is not to shape, but how to pour copper juice into the model, and there can be no bubbles in the middle, the ancestors in order to overcome these difficulties, the wisdom to the extreme, will make a complete set of organs specially used for watering, and the production of these organs can be much more complicated than simply shaping the copper tripod, even if there is a problem in one link, it may lead to the casting failure of the entire copper tripod.

Liu Yi was designing this mechanism the most during this time, and it should not be too far away from the model, otherwise the copper juice would have to solidify in the process of flowing, and the material of the mechanism itself must have enough thermal 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, which is likely to directly damage the mechanism, and in the process of copper flow, there will definitely be a part of the loss, so before smelting, this must be taken into account.

If it weren't for the fact that he could strengthen the furnace temperature with the help of the power of the five elements of the building itself, Liu Yi would not dare to guarantee that he would be able to do a good job of this three-zhang high copper tripod at one time, and in terms of time, he would not have been given a second chance to cast the tripod.

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

"My lord, the Pavilion Marquis has orders, no one is allowed to enter!" When Guan Ping saw Liu Bei coming, he hurriedly stepped forward and bowed to Liu Bei.

"Oh?" Liu Bei looked at Guan Ping in surprise and said, "I heard Wen Chang say that Bo Yuan has been in this for seven days, and he hasn't finished it yet?" ”

He wanted to see the altar, but when he arrived in Hanzhong, it happened that Liu Yi was ready to start the final process, and the entire altar was blocked by Liu Yi building a seven-zhang high shack for one mile.

"Not out yet." Guan Ping shook his head: "According to Tinghou's words, this shed should be absolutely sealed, with only a few small windows, and every day meals are sent in from these places. ”

"That man must not be suffocated?" Zhang Fei glared in surprise.

"This ......" Guan Ping didn't know how to explain: "It should be fine, there are also food plates sent out in the breakfast today, according to what Tinghou said before blocking this place, it should be the time for success in these two days." ”

The altar has long been done, and now what Liu Yi is doing is the big tripod used to sacrifice to the sky, and it is impossible to test how big the nine tripods cast by Dayu in the past are, but now Liu Yi wants to cast the copper tripod, I am afraid it can be called the most in the world.

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

The three brothers waited for a long time and didn't see any movement inside, so they prepared to go back to Nanzheng, after all, Liu Bei had to prepare for the upcoming sacrifice of the king in the past few days, and the envoy of Dongwu also came.

It's a pity that I won't have a chance to see it for the time being.

Time passed bit by bit, seeing that the day of the Double Ninth Festival was coming, but the huge shed that wrapped the entire altar had not been demolished, and Liu Bei couldn't help but feel a little worried in his heart, Liu Yi was okay, right?

"The lord doesn't have to worry, Bo Yuan has always been measured in doing things, this time for the matter of congratulating the lord and the king, Bo Yuan said that he would cast the first tripod in the world to congratulate the lord of the king!" Zhuge Liang smiled and said with relief, in fact, he was also a little worried.

"Actually, you don't have to bother so much." Liu Bei shook his head and said, now that the overall situation has been decided, what is missing is just a ceremony, in fact, since Qin ruled the world, although this kind of sacrifice is still important, but the sense of ritual has gradually surpassed the actual meaning, although the princes attach importance to it, but in fact, the degree of attention and attainment can not be compared with before the pre-Qin.

In the case that the overall situation has been decided, according to Liu Bei's meaning, in fact, the meaning is fine, there is no need to be too extravagant, he was somewhat distressed after hearing about the money spent on the casting of the altar this time.

Zhuge Liang smiled but said nothing.

On the eighth day of the ninth lunar month, just one day before the Double Ninth Day, news came from the altar that the huge shed had begun to be dismantled, and the ceremony could be held as scheduled.

The whole Nanzheng suddenly began to get busy, Wei Yan mobilized soldiers and horses to go around to be responsible for maintaining order, this time in order to confirm the legitimacy of Liu Bei's claim to be the king, the people were allowed to watch on the periphery, not to mention that there were many scholars from all over the world who came to watch the ceremony, from this point of view, Liu Yi wanted to make this sacrifice more beautiful, and it was not wrong, at this time it was not just a sacrifice, but also the meaning of showing national strength.

However, at this time, Liu Bei obviously couldn't go to see it in person.

On the ninth day of the ninth month of September, the day of the Double Ninth Festival, Liu Bei led the hundred officials of Jingshu to the altar, accompanied by the Jiangdong envoy Kan Ze and the accompanying Jiangdong envoy group.

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

The altar is about three zhang high, but it does not look abrupt, divided into three layers, above the altar, nine red dragons are lifelike, with the momentum of nine dragons facing the sky, the dragon head is facing the direction of the center of the altar.

At the top of the altar, there is a prototype platform of about ten zhang, but the inside is a square copper tripod, three zhang high, and one zhang wide, which was not an abrupt altar, but here it is a strange peak protrusion, giving people a visual impact, the copper tripod on the altar, making people give birth to a visual dislocation with Tianqi, the closer you get, the stronger the feeling.

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

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

Liu Yi walked down with a tired face, bowed to Liu Bei and said, "Lord, fortunately, I am not dishonored!" ”

Looking at Liu Yi's tired look, Liu Bei hurriedly stepped forward to help him and said, "Bo Yuan doesn't have to be like this, the time is just right." ”

At this time, it is not convenient to say too much, after a few simple instructions, Liu Bei asked Liu Yi to step back first, and after preparing for this matter, he would reward Liu Yi well.

"Boom~" Skyrim, there is lightning streaking, this is not a good sign, but since the date is chosen on this day, at this time, it is impossible to change it, after all, this kind of thing, the hour is pinched.

When Liu Yi turned around, he quietly glanced at Liu Yi, tacitly.

Silently retreated to the train, and the sacrifice officially began at this time, and the officials in charge of this began to perform the sacrifice step by step.

Worship the ancestors, slaughter three animals for the best, then worship heaven and earth, and finally go to the second layer of the altar, want to read the sacrifice text, to the effect that it is to prove the rationality of calling himself king.

Liu Yi looked at the altar, and it was a little incredible, at the moment when the copper tripod was completed, it seemed to be integrated with the altar, and no new attributes appeared, which made Liu Yi a little puzzled, in his craftsman career, this phenomenon was the first time, and there was no experience, and some wasted so much of his new learning.

"Boom~"

At the moment when Liu Bei finished reading the sacrificial text, a thunderbolt suddenly descended, and fell fiercely on the copper tripod IQ, the strong light that flashed at that moment and the thunder that seemed to explode in the ears made everyone fall into a temporary state of blindness and deafness at that moment, and the thunder and lightning fell on the copper tripod accurately.

There was a commotion around, and the people in the distance began to discuss, and the officials were also a little worried.

Zhuge Liang also looked at Liu Yi worriedly, he calculated that there would be a thunderstorm on this day, but he didn't expect this scene, if it is not handled well, Liu Bei's prestige may be greatly lost.

Liu Yi didn't speak, just looked at the copper tripod on the altar seriously, and it took her a lot of thought for this scene.

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

Many people's eyes subconsciously wandered around, searching for possible changes, and soon someone found that the bronze tripod above the altar had cracks, and it was constantly expanding, and it may not be clear from afar, but some of the closer ones could be seen very really, but under the cyan skin, there was a faint red color revealed.

Immediately after, the surface of the bronze skin gradually fell off, fell into everyone's eyes, the bronze tripod was not destroyed by lightning as imagined, but after the surface of the copper skin gradually peeled off, a red copper tripod appeared, a red dragon carved in the body of the tripod IQ appeared lifelike.

And in the most eye-catching place of Tongding, there are five big characters: the Han family is here.

The original questioning voice, after the appearance of these five big characters, gradually weakened, Liu Yi and Zhuge Liang glanced at each other, and bowed to Liu Bei first: "God bless the big man!" ”

"God bless the big man!"

The others also gradually reacted, and fell to the ground excitedly one by one, no matter how many of these scholars present believed, but at least, at this moment, most of the people believed that Liu Bei would become the master of Zhongxing, and their attitude towards Liu Bei was more pious than before......
