Ever since the idea of ​​using thunder instead of wood energy to make elixirs came into Xiao Yu's mind, he was out of control. He even wrote the first paper dedicated to this idea to fight against the world.

"On the Feasibility of Thunder and Fire Alchemy"

In order to perfect this idea, Xiao Yu began to experiment.

He has no money now. He only has 500 gold coins saved from the fees Xiao Zhan sent over the years.

Five hundred gold coins is quite a lot. This amount of money can allow an ordinary family to live a happy life, but it is still too little to buy medicinal magic core.

Low-level medicinal materials of young age, each starting with at least a few dozen gold coins, a first-level magic core, not to mention the price of four to five hundred...

The most important thing is the medicine cauldron. The basic medicine cauldron costs thousands of gold coins each. This is not something Xiao Yu can afford at all.

He didn't want the five hundred gold coins to go to waste, so the surrounding flowers, plants and trees would be in trouble.

Since there are no medicinal materials, flowers, plants and trees should be used instead of medicinal herbs to refine them. Xiao Yu does not want to actually make alchemy now, he just wants to verify the thunder and fire alchemy method, and these plants and trees are enough.

…………

After spending a whole morning, Xiao Yu collected a lot of flowers and plants, a few trees, and some fruits and vegetables.

As for the alchemy furnace, Xiao Yu planned to use an iron pot for cooking instead.

Buckle two iron pots together, then weld them with fire attribute Dou Qi, make three small iron pillars below to support them, and poke two round holes under their abdomen to serve as fire outlets.

A simple (broken) version of the two-mouth cauldron appeared in front of Xiao Yu.

"Huh~"

Xiao Yu took a deep breath and shook his hands: "Okay, get ready, let's start refining the pill!"

Xiao Yu stretched out his left hand, and yellow flames spurted out. Generally, if you want to condense real fire with fighting spirit without resorting to the medicine cauldron, you need the strength of a fourth-grade alchemist. However, due to Xiao Yu's special physique, there are two differences.

Source fire, which is only strong but not weak, is naturally not included in this list.

Carefully control the flame to enter the medicine cauldron. If you don't pay attention, there are some signs of melting at the mouth of the fire. Xiao Yu is so frightened that he quickly controls the temperature of the flame to decrease.

These were the only two cooking pots he had, and he would have to buy new ones if they ran out.

After seeing that the flames stabilized, Xiao Yu grabbed a weed with his right hand and threw it into the medicine cauldron.

The moment the weeds came into contact with the flames, they withered and turned black. Within a few seconds, only a layer of ashes remained at the bottom of the cauldron.

Xiao Yu shook his head slightly: "I didn't expect that the first refining failed. The flame temperature was still too high."

"Yes, after all, it is not a real medicinal material. It is normal for it to have poor fire resistance."

"continue."

He is not discouraged. If it doesn't work this time, he will try again.

that's all

Second time, failed

The third time, failed

The fourth time, failed

…………

Finally, on the ninth time, Xiao Yu successfully extracted a ball of pink essence from a flower.

Looking at the flower essence in the medicine cauldron, Xiao Yu smiled happily.

The first time I extracted the essence, I actually used it nine times. It seemed that my talent in refining medicine was still lacking.

He thinks so

But everything is difficult at the beginning. Now that he has succeeded in the first step, the rest of the extraction will be much simpler.

Following the previous steps, Xiao Yu began to refine one piece of grass, one piece of wood, one grape, and one sweet potato.

Anyway, just throw whatever you have into it. With the experience refined previously, it will be much smoother this time.

After extracting the essence of many plants, Xiao Yu began the next step, tempering!

A bright thunderbolt appeared in his right hand, violent energy surged, and was firmly trapped in his palm. Xiao Yu carefully sent it into the medicine cauldron.

With the previous experience of controlling flames, Xiao Yu did not dare to be careless this time and controlled the intensity of thunder and lightning to a minimum.

The extracted essence squeaked the moment it came into contact with lightning, and black smoke erupted. Xiao Yu didn't care, because the black smoke was the impurities remaining in the essence.

After all the essences were tempered, Xiao Yu found that compared with before, these essences were much clearer and brighter.

This step can be regarded as electrolytic purification, which is to remove impurities and retain purity, and the authenticity is perfect.

The last step, melting the elixir, is the most difficult step. After all, medicinal materials have different medicinal properties. If the flame is not controlled well, the essence will be instantly reduced to ashes, and the energy in the medicinal materials will also explode, causing the furnace to explode.

This is why wood gas is used as a catalyst. Medicinal materials belong to wood, and wood gas can neutralize the medicinal properties and catalyze the fusion of elixirs.

Xiao Yu slowly moved the tempered essence closer and looked nervously at the situation inside the medicine cauldron.

When the essences touched together, Xiao Yu's soul perception noticed resistance, but the resistance was not great.

He instantly understood that these were not the essence of medicinal materials after all, and had no conflicting medicinal properties, but only had weak properties to block them.

If this is the case, Xiao Yu can directly forcibly fuse them together, but he does not intend to do so.

After all, the focus of this experiment is whether thunder can replace wood energy and solve the problem of conflicting medicinal properties.

Xiao Yu once again put the thunder and lightning into the cauldron, starting from the smallest power.

After a little testing, the essence still showed no intention of merging together. Gradually, it was evening.

Xiao Yu did not lose patience and continued the boring fusion.

Finally, after increasing the intensity of the lightning to one-tenth of the power he could unleash, the essence in the cauldron trembled and quickly merged together.

The thunder and lightning finally broke through the parts of the flower and plant essences that were blocking each other, allowing them to all merge.

Just like the properties of substances are determined by molecules, and molecules are composed of atoms, to fuse two substances with different properties and combine their properties to produce better properties is to recombine the atoms of the two substances into

New molecules form new substances.

The same goes for refining medicine, which is to reshape different medicinal materials from the molecular level and combine many medicinal materials atoms to form new molecules. The properties of substances are determined by molecules, so the new combination and arrangement of molecules become new substances.

, that is, elixir.

Like water, water is composed of water molecules, which are composed of two hydrogen atoms and one oxygen atom.

The function of thunder and lightning is to disrupt the original essence molecular structure and reorganize each other to form a new stable molecule. The new molecules are then composed of substances. The substances are blended into a round shape to form an elixir.

The most difficult and critical process of melting the elixir has been completed by Xiao Yu, so the next step is to form the elixir. This step is very simple. You only need to wait for the fused essence to cool down stably and form the elixir, and then it is ready.

This step did not take Xiao Yu much time.

After a while, a freshly baked "elixir" appeared in Xiao Yu's hand.

"Hahaha... I did it, damn, I did it!"

Looking at his masterpiece in his hand, Xiao Yu smiled very happily. Even in the past twenty-three years on earth, he had never studied or done one thing so seriously.

But in Dou Po World, he broke the iron law in Dou Qi Continent's history that alchemists must bring wood into the fire. He felt an overwhelming sense of accomplishment.

If there is a thesis system in this world, then Xiao Yu can definitely win the Alchemist Lifetime Achievement Award for his "On the Feasibility of Thunder and Fire Alchemy"!
