Near the volcano, there is a group of buildings made of firebrick. Under these buildings, there are fire veins. In the fire veins, there are thousands of years of underground fire. The temperature of these underground fire veins is very high, which is easy to melt gold and break iron. It is the lowest kind of strange fire between heaven and earth.

The ground fire overflowing through the cracks in the earth's crust was built into a pool of ground fire. Through the seal control of the array master, it can be used to rent to the caster or alchemist to refine the alchemy. After all, refining the alchemy with his own refining flame or real fire is a great consumption of soul power and truth.

The earth fire pool is suitable for those who want to practice weapon refining or alchemy for a long time.

ChiYan Luo family also has a fire pool here. There are three fire rooms on the fire pool. These three fire rooms bring a lot of benefits to the Luo family every year. Moreover, the benefits are long-term and have no cost. This is one of the reasons why Liu family is greedy for Luo family industry and wants to drive the Luo family out of ChiYan city.

There are more than ten such dihuochi and ChiYan City, each of which is owned by at least the second-class forces of ningyuanjing. Now, ChiYan Luo family is so lonely that there are only three Xiannai Qijing masters, but only one third class force has one dihuochi and three Dihuo rooms. How can it not make others greedy.

If you have Baoshan, you should also have the strength to protect it. Otherwise, it can only attract others' covet.

Now, Luo Yu is in a special casting chamber of the Luo family. The temperature in the chamber is extremely high, with an appalling temperature of more than 60 degrees. If ordinary people who have no accomplishments stay in this place for a while, they will dehydrate and die. Only martial arts dare to stay in this place for a long time.

There is no other furniture in the underground fire room. There is a futon on the ground and a pool full of water for quenching. In the middle is a deep round hole the size of a human head. The red light can be seen in the deep. The underground is the underground fire pool. There are five low stone pillars around the fire opening. This is a third grade fire gathering array. The stone pillars are carved with mysterious patterns. There is also a notch on the top to place the Yuan Stone to start the array. As long as you put the yuan stone into the array, you can start the array and lead up the underground fire.

Luo Yu put a Yuan Stone on each of the five pillars. Suddenly, the light on the pillar was flowing, and the array was used by one of them. A traction force was used on the fire mouth. The fire mouth roared up a red flame. The flame rose more than one meter high, and the temperature in the fire chamber rose more than ten degrees again.

Luo Yu puts the melting furnace of the fourth grade treasure rank given to him by Emperor Zhonghao of heaven and earth on the top of the fire. The inscription on the red copper furnace immediately absorbs the burning power of the earth fire and ignites a more pure earth fire in the furnace.

Luo Yu asked the red copper stove to warm up slowly at the mouth of the stove, and then put a lot of ore materials in the storage bag in the underground fire chamber. All kinds of ores occupied most of the area of the underground fire chamber. Then forging table, hammer, tongs, Kaifeng stone and other objects were also taken out.

When the melting furnace warms up, Luo Yu puts a five Jin piece of bronze into the melting furnace. This time, he still wants to refine a bronze sword. The last time, he was instructed by Hao Lao, but this time, he wants to refine it alone.

Put your hands on the red copper stove, and the real Qi and soul power flow into the stove to control the ground fire and melt the bronze.

Although the soul power of the martial arts who have not reached the spiritual realm has not degenerated into divine consciousness and can be released from the air, the casters or alchemists who have stronger soul power than ordinary martial arts can use their soul power to perceive and control the fire in a short distance, which is one of the reasons why the casters and alchemists have high requirements for soul power.

Because of his last refining experience, Luo Yu knew the melting point temperature of bronze, controlled the temperature of the flame to reach the melting point temperature of bronze, and the bronze soon melted into molten iron. Then he controlled the flame at a constant temperature to purify the molten bronze and remove the impurities.

A moment later, a third of the volume of the molten iron of the bronze was smaller and suspended in the red copper furnace. Luo Yu slowly lowered the temperature. At the same time, he used his soul power to pull the molten bronze into a long sword shape and slowly put it out. The bronze also condensed into a long red sword shape.

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
