Although the blood-burning secret technique of "Copper Puppet Gong" can smelify copper, during the copper smelting process, there must be copper elements not absorbed by the copper smelting heart. For example, when the copper element reaches the boiling point, a part of the copper element will inevitably be vaporized, and this part of the copper element is not absorbed by the copper smelting heart, so it falls into the human body. Over time, metal will naturally be poisoned.

However, this disadvantage is not a big problem for Li Xiao. He is immortal and even metal poisoning can excrete harmful parts from the body through metabolism.

No matter how you look at this technique, it seems to be tailor-made for him.

"Zhang Long, if you go to the warehouse to find the accountant, you will say that I need a lot of copper here. No matter what method he uses, I will see the copper I want tomorrow, the more the better."

Li Xiao decided to practice "Bronze Puppet Kung" first, but the name "Bronze Puppet Kung" is somewhat unreal. Although its original intention is to refine copper blocks into puppets, Li Xiao thought it was more appropriate to call it "Bronze Refining Technique".

Anyway, the original is dead now.

Li Xiao simply changed the name of this technique to "Bronze Refining". Anyway, zombies and ghosts cannot practice this technique, and living people will also be poisoned by metals when practicing this technique. Only he can practice this technique, so the naming rights will naturally belong to him.

When Zhang Long received the order and left, he ordered Guihu to close the door and return to the bed to start practicing.

The first step in "Bronze Smelting" is to refine the copper elements in the body and first form the heart of copper smelting.

In fact, this copper smelting heart is equivalent to the core. Some of the copper refined later is used to strengthen the copper smelting heart, and some are controlled as puppets.

"The secret technique of blood burning, get up!"

Li Xiao sat cross-legged on the bed with his eyes closed. He first sensed the flow of qi and blood in his body, and then stimulated the blood by absorbing evil energy. This step is easy for ordinary people, but it is very difficult for him, because once evil energy enters the body, it will be absorbed by his lower body in a blink of an eye.

It took him four hours to complete the first step of the Blood Burning Secret Technique.

Under the stimulation of evil energy, the blood temperature in the heart slightly increases, and then the copper element in the body is sensed. This step is actually very easy.

Of course, this is because Li Xiao is born with mental power far beyond ordinary people. Ordinary people may be able to complete the first step in such a large corpse-raising site, but they will be stuck in the second step and cannot sense any copper elements at all.

But Li Xiao was just the opposite. The first step was extremely difficult, but the second step was natural. In a blink of an eye, many copper elements were gathered in the heart.

Next is the water grinding process, constantly absorbing evil energy and stimulating blood, and refining the copper elements that gathered little by little.

After all, it is smelting copper in the heart, and the danger is extremely high. It is impossible to refine all the copper elements in an instant. If you are really eager for quick success and instant benefits, you probably will be smelting your heart before you start smelting copper.

Li Xiao practiced for a whole night.

The next morning, he opened his mouth and spit out a mouthful of white smoke. The white smoke fell to the ground and turned into little brass. The amount of brass was very small, smaller than the beads of the ballpoint pen tip.

When he opened his eyes to the brass, the brasses were influenced by his thoughts and jumped around on the ground, but in the end they did not fly back to the palm of his hand as he wanted.

“The control is too weak.”

Li Xiao sighed, and then ordered Guihu to open the door to see if the copper block he wanted was delivered.

Facts have proved that the most important part of the practitioner's wealth is indeed ranked first.

Li Xiao leaned against the royal palace and didn't have to wait for a day to practice resources. When Guihu opened the bedroom door, Li Xiao saw a large number of copper blocks piled up into a small hill, which was enough for him to practice "Bronze Refining" until he was able to achieve great success.

With enough copper, Li Xiao immediately ordered Guihu to move the copper block into the room, and sat on a chair and began the great cause of copper smelting.

In the next six months, Li Xiao stayed in the door and devoted himself to the great cause of copper smelting.

Although Li Zon-King and Madam Eight would occasionally come to see him, delaying his great copper smelting career, the overall process was still stable and there were no accidents like assassins.

"I have fully mastered the principle of bronze smelting in the past six months, but why does bronze smelting only smelting copper? It is obvious that the melting point of gold is lower than that of copper."

Li Xiao was not practicing completely mindlessly while smelting copper, he would also have his own ideas.

For example, expanding the "Bronze Smelting" into alchemy, iron, silver, steel, aluminum...

So Li Xiao began to experiment on his own, first of all, alchemy.

The melting point of gold is indeed a little lower than copper. Since it can be refined copper, it can naturally be refined. However, as the amount of gold he refined increases, he found a problem: gold is heavier than copper, and when the quantity is small, it doesn't matter much. However, when the amount of gold continues to increase, the disadvantages begin to appear.

Gold is far less convenient to control. With the same weight, there is more copper and harder, while gold is smaller and softer.

In fact, there is another point, that is, cost-effectiveness.

The material needed for bronze smelting is only copper, while the material needed for alchemy is gold. If Li Xiao had not been born in the royal palace, there would have been so much gold smelting.

Therefore, alchemy is not as good as bronze smelting in all aspects.

After Li Xiao confirmed that the gold was not suitable, he only retained a small amount of refined gold, and the remaining gold was returned to the warehouse.

Next, he will come to iron blocks and try iron smelting.

Iron is cheaper than copper in this world, and can even be advanced to steelmaking, with a cost-effectiveness far exceeding copper smelting.

But soon he realized why the original creator did not use iron, because the melting point of iron is higher than that of copper, and it is much higher.

At the same time, copper smelting is much faster than iron smelting.

Li Xiao sacked the power of the nine ox and two tigers and finally refined a piece of iron. In the end, even he could not stand the efficiency himself, so he would have achieved half the result with twice the effort.

As for the remaining several materials, there are similar problems.

However, the silver problem was not particularly big, so Li Xiao refined a lot of silver, and as for the remaining various materials, he also refined some of them. In the end, he shifted his focus back to the copper smelting.

After some experiments, he had to admit that copper is the most suitable material and copper smelting is the most suitable road.

Late at night, while he was smelting copper, two ghosts emerged from the ground in a small building hundreds of meters away from the royal palace and gathered quietly.

"Thousands of mountains and rivers are just to win the heart of yours!"

"The sea will be destroyed and the rocks will be destroyed, and you will be able to take the king's life!"

As soon as the two ghosts met, they immediately spoke their code words.

After confirming that each other's code is correct, the two ghosts let down their guard.

"Nightmare Realm, open!"

One of the ghosts whispered, and the inner space of the small building was immediately separated from the outer space.

"Bai Jue, who is the target this time? He actually wants us to take action at the same time?" Another ghost spirit saw that the Nightmare Realm had opened, and his speech returned to his normal tone.

One of them is called Bai Jue and the other is called Hei Jue. Together, they are the two masters of Black and White. They are a famous killer combination in the killer world of the Zombie Dynasty. Once they are targeted by both of them, as long as the target is not the Zombie King, they will undoubtedly die.

Bai Jue was wearing a white robe and a Shura mask on his face. He spoke, "This time his target is Li Xiao, the youngest son of King Li Zon!"

"Li Xiao? This little kid with a stinky breast should be only... seven... eight years old? Who is so cruel and ruthless?" Hei Jue was wearing a black robe and a Rakshasa mask on his face. After hearing this, he said in confusion.

Bai Jue replied: "The employer's identity is unknown, but it's easy to guess. It's just that the ghost king in Donghe Mansion wants to destroy the seven emotions of King Li Zon. There are rumors that King Li Zon prefers his youngest son. If Li Xiao dies, and his soul is scattered and his body is broken, will King Li Zon be angry?"

"Will that Ghost King be nearby? Once King Li Zon is angry, he will take action and use the Seven Emotions Divine Art to ignite King Li Zon's anger?" Hei Jue guessed.

Bai Jue smiled and said, "That's nothing to do with us. We only have one task, that is, kill Li Xiao, and what comes later has nothing to do with us."

"It seems that the Zombie Dynasty is about to change again." Hei Jue sighed and then signaled Bai Jue to unlock the Nightmare Realm.

After Bai Jue cleared the Nightmare Realm, Hei Jue squatted on the ground, pressed his right hand towards the ground, and whispered: "Shadow, open!"

It was late at night, so after Hei Jue used his natural magical powers, there was no wave at all, but unlike the previous drilling ground, the ground was covered by invisible black shadows.

Hei Jue sank into the shadow and spoke, "Go!"

The two sneaked into the Shadow Road and quickly approached the Zombie Palace, without being shocked by anyone along the way.

In fact, the reason why the Black and White Sages succeeds in assassinating the target in every cooperation is precisely because the talent and ability of the two are extremely suitable for assassination.

Bai Jue's talent is called the Nightmare Realm. Once it is opened, it is isolated from everything. No outside world can know anything that happens in the Nightmare Realm.

Hei Jue's shadow path can turn shadows into passages. As long as the shadows are connected, it can reach them unimpededly and will not be discovered by anyone.

The combination of two talents becomes an assassination magic skill, which can sneak into anywhere and quietly assassinate the target.

After sneaking into the Zombie Palace, it didn't take too long to find Li Xiao's room. Zhang Long and Zhao Hu stood outside Li Xiao's door like a door god, without noticed that there were two ghosts passing by on the shadow on the ground.

In the room, Li Xiao was still smelting copper, while Guihu was lying next to Li Xiao to sleep.

"Nightmare Realm, open!"

Suddenly, the atmosphere in the whole room changed, Hei Jue and Bai Jue appeared in the room, and they rushed towards Li Xiao as quickly as possible.

The zombie defense is invincible, and the ghost spirit is unparalleled. Li Xiao did not react at all. The black and white double-jue had already come to him. The ghost tiger reacted very quickly and immediately roared and turned into a big tiger form. Before it could protect it, it was entangled by a large number of black shadows. This was the shadow path subtle wire of Hei Jue.

Bai Jue slapped Li Xiao’s forehead with a palm, and Li Xiao was immediately photographed on the wall, and blood spurted out from his facial features.

"The target has been killed, leave!" Hei Jue saw that Bai Jue was successful and immediately spoke.

Bai Jue felt something was wrong and refused, "No, he was not dead. It might be that King Li Zon gave him a magic weapon to defend himself, please make a quick break!"
