The bronze wrapped in genuine Qi is taken out. Luo Yu uses iron tongs to clamp the red bronze on the forging table and keeps forging. The beating sound of the hammer makes the room of the earth fire. Under the constant beating, the bronze is also beaten into a sword embryo. The blade of a thin sword embryo is beaten, and the handle and the blade of a bronze sword are finished.

Then Luo Yu put the bronze sword embryo into the red copper real fire and returned to the furnace for heating. When the sword embryo was red and reached the quenching temperature, it was taken out and put in the quenching pool.

The white smoke rose, the bronze sword was quenched by rapid cooling, and the hardness of the sword reached a very hard level.

The rest is to grind out the point of the sword with the open edge stone. At this point, a bronze sword of grade one is a success.

Luo Yu is holding a bronze sword. He bends his fingers and flicks. The body of the sword makes a clear sound. Listening to the sound, Luo Yu nods with satisfaction. It takes two hours to refine a bronze sword

the bronze cost of a bronze sword is only a few hundred taels of silver, and a successful bronze sword can buy ten pieces of inferior stone at a high price. From this, we can see the huge profits of the casting profession. Even if it's just a bronze sword, the caster can live a rich life by casting.

The weapons of the first grade are ten yuan stone, the second grade are thirty yuan stone, and the third grade can be sold at a high price of one hundred yuan stone. Once the weapons of the fourth grade are refined, the price will immediately increase ten times, and the high price of one thousand yuan stone can be bought.Luo Yu put the bronze sword aside, and put a harder piece of iron ore in the red copper furnace. This time, he wanted to refine the iron arrow for himself.

The black iron sharp arrow is also an ordinary weapon, but because of its small size, it is more difficult to refine than the bronze sword.

Sure enough, because of the first smelting of iron, Luoyu is not familiar with the melting point temperature, the first piece of iron ore was abandoned by Luoyu because of too high temperature.

Luo Yu frowned, and then controlled the red copper furnace. The waste slag was discharged through the special slag outlet under the melting furnace. Another piece of Xuan iron ore was put in. This time, Luo Yu learned to be smart. Instead of heating up quickly, he added up the temperature bit by bit to find the melting point temperature of Xuan iron.

It takes a lot of time to find the melting point slowly, and the caster is a process of accumulating experience. With more ore melted, he knows the melting point of all kinds of ore materials. Refining is very fast, just like Luo Yu refining bronze sword. Because he has refined it, the second refining is very fast.

In fact, the melting point of all kinds of materials is recorded in haolao's refining notes. However, Luo Yu doesn't want to rely on his refining notes for everything. He wants to find out for himself. When he meets problems that can't be solved, he goes to see haolao's refining notes. Only in this way can he really improve his refining skills.

Just as we do in the exam, we will tell you the answer directly, but you don't analyze the way to solve the problem yourself, so your score can't be improved.

This time, it took Luo Yu an hour to find the melting point. He smelted five pieces of Xuan iron ore. It was not until the sixth time that he really found the melting point of Xuan iron ore.

Melt, purify, eliminate impurities, forge, fail, melt again, purify And time goes by little by little
