Lu Zhi wanted to refuse, but Liu Bei took it upon himself to send the knife to Lu Zhi's residence.

This seven-day knife forging process uses Julu's top forging technology, including the double liquid quenching method of grease and urine, the steel wrapping method, the carbon kiln carburizing method, and the earth-covered blade burning method.

These technological improvements, double-liquid quenching makes the blade tougher, and steel-coating makes the blade both hard and tough, which greatly reduces the cost of making long knives and increases the overall strength of the blade. The carbon kiln carburizing method solves the problem of blade wear and tear.

The disadvantage of carbon becoming soft increases the hardness of the blade.

In short, due to the use of many forging techniques, the dozens of long knives forged are all of high quality.

Among the dozens of knives that Lu Zhi took, there were one with five-foot-long knives, three with one-foot-long knives, three with nine-foot knives, twelve human-high seven-foot knives, and then, one regular-sized war horse knife.

Fifteen handles.

Back at his residence, Lu Zhi looked through the many fine knives and couldn't put them down.

From Lu Zhi's perspective, any one of these dozens of knives is better than the hundred-refined sword he once had.

Especially the long sword with a handle of 15 feet, Lu Zhi was very impressed. He marveled at the amazing skills of the Julu craftsmen. You know, the longer the knife, the easier it is to break, so the longer the knife, the blade is made.

The wider it gets, and like the Changque Dao, the knife is more than ten feet long, and the widest part is less than three fingers wide. However, the blade is still very strong and strong, which is incredible.

The key technology for making long knives lies in the steel-wrapping method.

According to Jian Yong's experience of selling goods in Luoyang, in Luoyang, a long knife handle is worth tens of thousands of dollars. The method used by Luoyang craftsmen to make long knives is to forge the whole body hundreds of times. Not to mention the high labor cost, the toughness of the blade is still somewhat insufficient.

Julu's steel-clad long knives cost only three to four thousand yuan to make. Moreover, Julu's long knives have advantages in length and toughness. This makes the cost of Julu's long knives to produce long knives.

Several times less than elsewhere.

In turn, the profit will be several times higher.

If Julu exports swords, it can only make enough profits by exporting high-end products. Others can also make ordinary daggers, daggers, and spear heads. There is no threshold, and there is not much competitiveness in selling them. Only long knives can be sold elsewhere.

Although it can also produce long knives, its output is far less than that of the giant deer, and its long knives are not as long as those of the giant deer.

The price of the Julu Changdao is 10,000 yuan, and the profit is only 1,000 yuan, while the Julu Changdao is priced at 8,000 yuan, and the profit is only 3,000 yuan. This makes the Julu Changdao unparalleled in competitiveness and has

Huge profits, just sell a long knife, it is a profit of several thousand dollars.
