In the room, Ye Kai came back to his senses for a long time.

What he saw just now was the memory that Jian Jizi had sealed in the cold iron marble during his lifetime.

And what he demonstrated to Ye Kai was a swordsmanship called Imperial Sword Technique.

There are no bells and whistles in this swordplay, and there are only three moves in total.

One is the early sun, the second is the polar night, and the third is the return to the yuan.

To perform the first move, the first move requires the cultivation of the foundation building period, the second move can only be used during the Dan period, and as for the third move, it must at least reach the Yuan Infant stage.

So to put it simply, Ye Kai can't use it at all now.

I can only save this force for later......

Fortunately, to cultivate this sword technique, you need to use your own essence and blood to refine a natal sword every day, and after the first sacrifice is seventy-seven and forty-nine days, even if you can't reach the foundation building period, you can still do simple sword flying and sword attacks, which makes Ye Kai feel some comfort.

With this sword technique, there is a little more power for self-preservation.

In the future, if you see who is unhappy, you can kill him a hundred meters away with your fingers, this is called cultivating immortals!

Thinking of this, Ye Kai couldn't help laughing, and then poured the cold iron marble out of the medicine pod, took out the medicinal materials he had just bought in the pharmacy, and prepared to try refining an alchemy.

At the back of the "Divine Pesticide Sutra", there are several introductory pills that can be practiced, among which there are just the pills and refining methods of the Qi Gathering Pill, so Ye Kai plans to use it to practice his hands for the first time.

【Qi Gathering Pill: A Grade Inferior Pill】

[Function: Can increase the monk's qi gathering speed by five times]

[Medicinal materials required for refining: four five-year-old ink leaf lotus, two mature ambergris fruits, one 3-year-old spirit gathering grass, plus two iron bone flowers that will not bloom]

【Refining method: ......】

In his mind, information about the Qi Gathering Pill gradually emerged.

Ye Kai followed the pill prescription and divided the medicinal materials such as the Ink Leaf Lotus, the Snake Saliva Fruit, the Iron Bone Flower and the Gathering Spirit Grass into multiple portions, and arranged them neatly on another table, in case there were any omissions in the process of alchemy.

After doing this, Ye Kai sat cross-legged on the ground, meditated for about half a pillar of incense, and adjusted his state to the best.

Then he got up and activated the Purple Cloud Medicine Ding's Fire Separation Array.

Clusters of flames erupted from the bottom of the pod, and the temperature in the room instantly increased.

Ye Kai's eyes reflected the firelight, and his heartbeat slowly accelerated.

At this moment, he thought of the old doctor again.

He had vowed to become an excellent alchemist with his last wish.

Hang the pot to help the world, cure the sick and save people.

Now, although his wish has deviated, he has finally come to this point.

"Ye Lao, I hope you have a spirit in the sky, and don't blame me for being selfish. It's not that I don't want to treat the sick and save others, but it's really hard to protect myself, so how can I have the spare strength to heal the sick and solve the worries of others!"

Ye Kai muttered softly, and when he stared at the Ziyun Medicine Ding again, he was already distracted.

Feeling the temperature of the Purple Cloud Medicine Tripod to a certain extent, Ye Kai no longer hesitated, and immediately reached out and grabbed it, and directly threw the four ink leaf lotuses into the Medicine Tripod.

However, in a single breath, the four black leaf lotus plants were burned into a large dark green liquid by the fire in Dingnei, and gradually evaporated as the temperature rose, and finally condensed into a drop of verdant water the size of a pearl.

Seeing this, Ye Kai hurriedly threw the two snake saliva fruits into the medicine tripod, the latter melted in an instant, and the juice was like two rebellious spirit snakes, bumping into the tripod, and always refused to blend with the verdant water droplets.

This is a situation caused by the clash of medicinal properties, which is introduced in the "Divine Pesticide Sutra", so Ye Kai was not flustered at the moment, but continued to put the Gathering Spirit Grass into the medicine tripod.

Using the spiritual power contained in the Gathering Spirit Grass as a guide, the spirit snake was lured to get closer to the verdant water droplets little by little, and the three eventually turned into one, turning into a light green spiritual liquid the size of a dragon's eye and as crystal clear as jade.

The next is the most critical link, which is to harvest Dan with iron bone flowers.

I saw that the two iron bone flowers that were about to bloom were driven by Ye Kai's spiritual power, and they wrapped the light green spiritual liquid up and down. At the same time, Ye Kai increased the fire, and the temperature of the medicine pod suddenly increased sharply, and the hard buds of the iron bone flower began to slowly fuse with the spiritual liquid little by little.

At this point in alchemy, Ye Kai's face couldn't help but show joy, and they all said that alchemy for novices is as difficult as climbing to the sky, and if you try it today, it is not as difficult as you imagined!

Ye Kai felt a little proud in his heart, and he almost shouted at the top of his voice, "Lao Tzu is really a fucking talent"!

However, the next moment this thought arose, the smile on his face suddenly froze.

Because at this time, for some unknown reason, the pale green spiritual liquid suddenly exploded without warning, and the spiritual liquid splashed everywhere, and finally turned into ashes under the calcination of the flames in the ding.

"it!"

"It failed!"

Looking at the medicine residue in the ding, Ye Kai was a little unacceptable for a while.

"This face hit too suddenly!"

Ye Kai's self-confidence took a small hit, but he didn't feel discouraged.

After all, it is the first time for alchemy, and failure is the most normal thing.

"The alchemist was originally piled up with elixir, and a failure is nothing. Just now, Lao Tzu was careless and didn't control the flames well, which caused the temperature inside the medicine pod to rise suddenly, which led to the failure of collecting pills, give me another chance, I will definitely succeed!" Ye Kai muttered to himself.

After that, he picked up the ink leaf lotus on the table and continued to alchemy.

......

......

"Hey, it is said that failure is the mother of success, if you don't have a good relationship with your mother-in-law, how can you get other people's cabbage?"

Half an hour later, Ye Kai blushed slightly, and silently used a shovel to shovel out the medicine residue in the medicine pod and pour it out, and the whole room was instantly filled with an extremely unpleasant smell of burning.

......

......

"it! Lao Tzu is refining pills, not steel!

"Mess with me?"

An hour later, Ye Kai frantically threw out the waste pill that had been refined with great difficulty, leaving a thumb-sized hole directly on the wall.

However, the walls were shot through, but the waste pill was still unharmed, and I couldn't bear to look at it directly.

Then another half hour passed......

The next two hours......

Before I knew it, the sky was bright.

Ye Kai sat slumped on the ground, staring blankly at the ceiling.

And next to him, there were mountains of pill residues and waste pills!

"It's just a little bit bit of a time every time, it's just a little bit of a difference!"

Ye Kai wanted to cry without tears, if it weren't for the fact that there was no one around at the moment, he would have doubted that someone was deliberately making a hindrance and hiding behind his back to watch his jokes!

"If you don't refine it, you won't practice it, no matter how many spirit stones there are, it won't burn like this, if you continue to refine like this, even if you don't die, you will have to die of distress sooner or later!"

So far, Ye Kai has never been so desperate and discouraged as he is today.

As he spoke, he got up from the ground and was about to put the Ziyun Medicine Ding back into the storage bag, but the prompt sound of the system in his mind suddenly sounded:

[Warm reminder: The system has detected that the grade of your medicine tripod is too high, which is not suitable for refining low-grade pills, which will cause the Dan Fang of the Qi Gathering Pill to deviate, and now it only needs to consume 30 points of combat power to adjust it, do you need to adjust it immediately?]

"Damn! What is the grade of the medicine tripod is too high, not suitable for refining low-grade pills, aren't you just referring to Sang Huai and saying that I cheated myself?"

Hearing this, Ye Kai was immediately furious, and his anger went straight to his heart, and he directly smashed the table behind him with his backhand.

It's definitely a conspiracy!

Aren't you usually jumping out of the warm reminder at every turn?

What's going on tonight?

Watching Lao Tzu work hard and busy for most of the night, wasting so many materials to stand up and speak, is it intentional to watch Lao Tzu's jokes?

"Isn't it just 30 combat power points? You said it earlier, it makes me look like I can't afford it!"

If it were changed to usual, Ye Kai might find a way to adjust the Danfang by himself for the sake of face and the system. But now, he spent most of the night focusing on alchemy, and his physical strength and mind were extremely consumed.

Therefore, although he was very aggrieved and helpless in his heart, he didn't have much heart to continue to fight with the system, and finally reluctantly chose to compromise.

[Okay, consume 30 combat power]

【Begin to adjust the prescription of the Qi Gathering Pill】

[Adjustment, please wait for ......]

[Congratulations, the adjustment is successful!]

Soon, a brand-new Danfang content appeared in Ye Kai's mind.
