The craziest upgrade system

"Intermediate alchemy?" Nie Yun chuckled, "God is really helping me!"

Immediately, various medicinal materials such as bone-washing flower, blood-strengthening grass, and purple golden moss were quickly purified under Nie Yun's superb techniques of intermediate alchemy.

"Yes, now that all the auxiliary drugs are ready, the next step is the main drug of the formula."

As he spoke, Nie Yun looked at the few medicinal materials on the ground.

Century-old blood ginseng, let’s start with you!

Nie Yun stretched out his hand, took out a smaller one from the only three century-old blood ginseng plants on the ground, and threw it into the alchemy furnace.

(Nie Yun originally only had one hundred-year-old blood ginseng in his hands, which was sent from the Spiritual Medicine Garden after the competition. The remaining two plants were listed on the list and were obtained directly from Nie Changmu.)

Throwing the blood ginseng into it, the Burning Stone Flame began to slowly approach the blood ginseng, using its own temperature to roast the essence of the medicinal liquid in the blood ginseng.

This process is slightly more difficult than other medicinal materials.

But Nie Yun was not in a hurry.

Years of experience have taught him that hot tofu cannot be eaten in a hurry, so he still needs to be patient and slow to extract it.

slowly.

A quarter of an hour later, the medicinal liquid of this century-old blood ginseng was extracted.

Take out the porcelain bottle and carefully fill the solution.

But at the same time, the half hour of using the flame elixir was up.

"Is it time for one thousand points?"

Nie Yun couldn't help but show a look of physical pain on his face. The expression flashed past and was suppressed by Nie Yun.

The next second, another flame-generating pill was redeemed from the system and appeared in Nie Yun's hand.

Next is the Xuetang flower.

........................

An hour later, Nie Yun returned to his original place, opened the door and strode out of the room.

Nie Feng, who was alert to the surroundings outside the house, immediately sensed Nie Yun's departure.

"elder brother…………"

Nie Feng opened his mouth to speak, but seemed to think of something and suddenly paused.

Nie Yun didn't reply, just looked at Nie Feng and nodded gently.

Arriving in the courtyard, Nie Yun noticed the firewood ash on the edge of the white clothes of Chun Lan and Xia Zhu, and he confirmed in his heart that while he was extracting the medicinal solution, Chun Lan, Xia Zhu, and Chun Lan were sitting next to the bathtub. , did not leave.

This made him feel more relieved.

"Little Lord!"

Seeing Nie Yun coming, Chun Lan and Xia Zhu naturally did not dare to neglect and hurriedly stood up to salute.

Nie Yun nodded slightly and then came to the tub.

This is a specially prepared large circular bathtub, nearly three meters in diameter and waist high. Sitting cross-legged in it is just enough to expose your mouth and nose for breathing.

The two maids kept adding water and firewood to the side.

Nie Yun stood aside and slowly poured many porcelain bottles into the bath barrel according to the proportion and order in the formula according to the medicinal bath formula in his mind.

It was fine at first, but the addition of various medicinal liquids slowly dyed the bucket of boiling water into a green or blue color. As the boiling water vapor continued to churn, it changed into various brilliant colors.

This scene is a bit like the scene in Nie Yun's previous life where the legendary witch made medicine.

But as the medicinal liquid of the last century-old blood ginseng and the medicinal liquid of the Xuetang flower dripped into the bathtub, it was like water and milk blending together, and the entire bathtub was dyed blood red in just an instant.

"Xiao Feng, take off your clothes and go inside."

Nie Yun pointed to the bathtub and said to Nie Feng.

After hearing this, Nie Feng felt a little palpitated when he looked at the bucket of blood, but he still took off his clothes on the spot and slowly entered the boiling bathtub.

After a while, his forehead was filled with water drops, and he couldn't tell whether they were water drops or sweat drops.

"Relax your body, don't resist, and run the exercises to absorb the medicinal power."

Nie Yun stared closely at Nie Feng in the tub and whispered instructions.

Looking at Nie Feng gritting his teeth with a look of pain on his face, it was obvious that the formula this time was much more painful than the last time.

As Nie Feng operated his skills, the thick blood energy in the bathtub water began to adhere to Nie Feng's body, turning into wisps of blood and drilling into Nie Feng's body.

What followed was bursts of painful screams from the pain that Nie Feng endured.

The blood color in the bathtub was slowly fading.

Two hours later.

After the medicinal bath was over, the whole bucket of blood turned into clear water again, while Nie Feng was as weak as he could, leaning against the bathtub, breathing heavily.

"Brother, this thing is much more powerful than the previous medicinal bath!"

Nie Feng leaned against the inner wall of the tub, breathing heavily and laughing.

After taking a few breaths and regaining his strength, Nie Feng jumped out of the tub and stretched out his hands to check in front of his eyes. Feeling the power in his body, Nie Feng let out a long breath.

Then he looked at a willow tree about the size of a couple's arms about three feet away, and took three steps at a time before arriving in front of it.

One punch.

A whistling sound of tearing apart the air suddenly appeared in my ears. The speed of this punch was so fast that only the afterimage was left.

boom!

A loud noise resounded throughout the courtyard.

The willow tree that the two people were hugging was actually pierced by Nie Feng's punch!

"So strong!"

Nie Feng was a little in disbelief. He looked at his fists and the willow tree in front of him. He just wanted to try it. Did he really punch through it by himself?

"Do you feel uncomfortable or is there something else wrong?"

Nie Yun walked aside and said with great concern.

"No, I feel that my physical body is much stronger than before. This medicinal bath is so magical!"

Nie Feng shook his head and said with a twinkle in his eyes.

"That's good, that's good." Nie Yun smiled and nodded slightly.

Then Nie Yun took out some spirit-gathering pills and gave them to Nie Feng, saying that he should practice first so as to experience the effect of the medicinal bath and consolidate the foundation.

This consolidation lasted five days.

During these five days, Nie Yun not only watched Nie Feng's every move, but also gave him a second medicinal bath. Because he was afraid that Nie Feng couldn't bear it, he diluted a lot of the medicinal solution the first time.

But the facts made Nie Yun even more excited.

In the second medicinal bath, Nie Feng even stepped from the peak of the ninth level of martial artist to the second level of martial artist!

This is the end.

Nie Yun was completely relieved about this new medicated bath formula and began to seriously start his own medicated bath.

Since it is your own medicinal bath, the elixir you choose is naturally the best.

Having prepared everything, just like five days ago, Nie Yun looked at the bucket of steaming boiling water in front of him.

Under the dancing of Chunlan Xiazhu's two pairs of dexterous little hands, Nie Yun took off his clothes, stepped into the tub and sat down cross-legged.

Outside the bathtub, Chunlan Xiazhu kept adding firewood and water to control the water temperature, while Nie Feng stood by with a serious face, like the most loyal guard.

In the bathtub, Nie Yun sat cross-legged.

As soon as Nie Yun's body came into contact with blood and water, he felt waves of heat surrounding him.

Then, under the operation of the Jiuzhuan Mind Technique, the heat that surrounded him began to turn into wisps of blood and penetrate into Nie Yun's countless pores.

In an instant, waves of heartbreaking pain hit his body like a tide.

This feeling is as if countless steel needles are constantly piercing your bones, and the skin, flesh, internal organs, etc. are like being cut with a dull knife, constantly being torn and torn again.

The pain reaches the bone marrow!

Even Nie Yun, who was a cultivator with an iron cloth shirt, frowned when facing such pain.

Under Nie Yun's control, the Nine Turns Heart Technique, the Iron Cloth Shirt, and the two profound level techniques began to operate in an orderly manner, absorbing the vast blood energy in front of him.

While Nie Yun was concentrating on tempering his body, something unexpected happened to the black flame in the space within his body...
