A rare opportunity

Chapter 189 Self-taught Alchemy

At this time, Wu Linger already felt pity for Li Yu, so she felt a little embarrassed when she saw him apologize first. She immediately shook her head and sighed:

"Oh! I can't imagine how you manage to survive every attack!"

Hearing this, Li Yu recalled the discomfort he felt when the attack occurred and couldn't help but shudder!

Feeling Li Yu's trembling, Wu Linger felt even more sympathy and pity for him! She unconsciously grasped his arm!

After a while, Wu Linger asked softly:

"Are you seriously injured? It's all my fault. I was too harsh!"

Li Yu couldn't help but feel a little creepy when he heard this! You know, Wu Ling'er is extremely abnormal now, which makes him very uncomfortable! He even suspected that Wu Ling'er wanted to use soft tactics to persuade him so that he could tell the whereabouts of the golden wood and the spiritual crystal fruit! He couldn't help but be alert and kept silent.

Seeing that Li Yu did not answer her question, Wu Linger continued:

"Ah! I know you hate me! Since the first time we met, you almost died in my hands, and your current injuries are also caused by me. But I really didn't mean it this time! Anyway, it doesn't matter whether you believe it or not. Since mother recognized you as her nephew, although I call you brother in front of mother, I still regard you as my enemy deep in my heart! But now, although I still cannot admit that you are my brother, I will never regard you as an enemy from now on!"

She talked to herself, as if she was talking to herself, but also as if she was telling Li Yu. In fact, only she knew that she was talking to herself! She wanted to confirm her inner thoughts through dialogue!

After hearing her words, Li Yu became more and more convinced that she had other purposes!

After Wu Linger spoke her mind, she seemed to feel relieved. She looked at Li Yu and said:

"Brother! Let me carry you!"

Without waiting for Li Yu to answer, he immediately put his arm on his shoulder.

Li Yu knew that the princess was moody and did not dare to resist, so he let her walk forward holding his arms.

When they returned to the mountain village, the moon was already above the treetops. From a distance, they could see Li He walking around in the moonlight. When he saw them coming back, he quickly came over to them. As they walked, he asked:

"What's wrong? Is everything alright? Is it hard to pick herbs?"

Seeing Wu Ling'er holding Li Yu's arm, he was shocked! He asked urgently:

"Ling'er! What happened to Yu'er?"

Before Wu Linger could speak, Li Yu spoke first:

"Aunt! Yu'er is fine! It's all my fault for being too greedy. I insisted on going to the edge of the cliff to collect a dendrobium and accidentally fell down! Fortunately, the cliff is not high, otherwise I would never see Aunt again!"

Li He couldn't help but feel scared when he heard this! He couldn't help but scold Wu Ling'er:

"Ling'er! Where have you been? Why did you let him take such a risk? If anything happens to Yu'er, I will not forgive you!"

Then he said to Li Yuwen:

"Yu'er! Let your aunt take a look at your injury. What exactly is it?"

Li Yu hurriedly said:

"Aunt! Yu'er's internal organs just suffered a little concussion. It has healed on its own. There is no need to worry about it, aunt!"

Li He didn't care whether he dealt with it or not. He immediately stepped forward and grabbed Li Yu's wrist and took his pulse! Well, his face changed drastically! He immediately lifted up Li Yu's other arm, and Wu Ling'er and he carried Li Yu back home.

If Li He had said this normally, Wu Linger would have felt depressed and jealous even if she didn't talk back! But today was a little different. Not only did she not feel depressed or jealous, she even felt that it was reasonable!

After nearly half a month of recuperation, Li Yu's internal injuries were basically healed, and he immediately tried to make the elixir.

The process of alchemy was described lightly in the Book of All Elixirs, so Li Yu took it for granted that alchemy was an extremely simple matter. But in reality, it was extremely complicated!

First of all, "Wan Dan Pu" says that alchemy requires precise control of the temperature, but it does not mention how to be precise!

The purpose of alchemy is to extract the essence of the herbs and then refine them into pills. However, the heat required to extract the essence of each herb is different! Some require slow boiling, while others require high heat and fast extraction. These must be precisely controlled according to the characteristics of the herbs!

At the beginning, Li Yu didn't understand. Either the herbs were burnt or there was no change for a long time. He was so anxious that he scratched his head and didn't know what to do. Fortunately, Li He encouraged him and dispelled his idea of ​​giving up alchemy. After countless failures, he finally boiled out the essence of the first herb by controlling the fire with his mind!

As the saying goes, everything is difficult at the beginning! With the experience of boiling the first herb, he summed up his experience through constant failures and gradually mastered the boiling skills.

But being able to boil out the essence of herbs does not mean that it can be refined into elixirs! It is just the first step in refining elixirs! It is also the simplest step!

The things that are boiled are not all the essence of the herbs, there are some impurities that need to be removed. And this removal process is not a simple filtration! The essence that has been boiled needs to be boiled again to remove the impurities! This requires more precise control of the heat to make the impurities precipitate and the essence remain.

A pill is not made from a single herb, but from several or even thousands of herbs! Some of the essences of these herbs are liquid, while others are solid. Refining a pill is not simply mixing these essences together, but blending them evenly!

Even if they are fused together, it is not over yet! The final pill is the key among the keys! Even if the previous process is done perfectly, if the pill cannot be formed in the end, only a pile of waste will be left!

In the whole process, the most critical part is the control of fire! Different stages have different requirements for fire, but Li Yu does not have his own fire after all, but relies on external fire, and this external fire is still mortal fire, firewood! It is conceivable how difficult it is to control the fire!

After a whole year, and after countless failures, he finally made his first pill! Although the pill was neither round nor square, and black in appearance, it was enough to make Li Yu, Li He, and Wu Linger ecstatic!

Li He couldn't help crying with joy, while Wu Linger rushed over excitedly and punched Li Yu, whose face was covered with cigarette ash! Li Yu was caught off guard and stepped back, tripping over a branch. He couldn't stop and fell backwards!

Wu Linger rushed over to grab him when she saw him. But in her panic, she didn't pay attention to her feet and stepped on the branch that tripped Li Yu. She rushed forward without stopping and rushed directly towards Li Yu!
