As soon as he entered the potion, Bi Fu couldn't wait for the whole person to jump out.

"Spent money, spent money, spent money!" Bi Fu frantically persuaded himself, forced to suppress his desire to give up, and restrained his legs from stepping out of the bucket with tenacious willpower, the green tendons on his neck burst out, and his face was flushed.

"Grandma's, this potion is the same on the outside!" Bi Fu scolded fiercely, both the experience and the appearance are very dark.

For no other reason, this potion hurts too much.

Bi Fu had never experienced this kind of pain in the past few years of cultivation, and even when he was exercising in the mortal realm.

As soon as I touched the potion, my whole body seemed to be pricked by dense needles, and the pain spread to my bones.

Extending all the way to his head, Bi Fu felt that his head had risen a little, and his teeth began to hurt.

After a while, the skin began to feel a burning sensation, as if it was roasted on a fire, and the appearance of the skin did not change, but it felt like it had experienced repeated burning and healing, tearing and recovery.

"Run the Turtle Hide." The cold mechanical sound of the system sounded in the sea of knowledge, like a plate of cold water poured on his head, which made Bi Fu's consciousness recover a little.

She subconsciously ran the exercises that had already been ripe.

The rampaging medicinal power in Bi Fu's body was guided, and he slowly walked along the movement of the exercises.

Bi Fu's consciousness also came to his senses.

Although the pain in her body has not been relieved in the slightest, at least it will be a great shock, so that she will not faint if she is in pain.

Bi Fu: You don't have to be so considerate, sometimes fainting is a kind of happiness.

"Don't waste your time, concentrate on running the exercises." The sound of the system interrupted Bi Fu's thoughts.

Bi Fu hurriedly retracted his mind and concentrated on guiding the medicinal power in his body, allowing it to wander around the tendons and veins in his body. The introduction to "Turtle Hiding Rest" first strengthens the muscles.

If the dantian is a reservoir, then the tendons and veins are the water pipes, and if the tendons are too fragile or too narrow, it will affect the absorption and use of spiritual power.

The same move, with strong and thick veins and narrow and fragile veins, the effect is completely different.

Bi Fu's move is to strengthen and stabilize the muscles and veins with medicinal force, so that the muscles and veins become tougher.

The principle of action is to continuously destroy the tendons and veins, so as to stimulate the tendons and veins to recover quickly and achieve a stronger state.

Of course, the control of the prescription is in place, otherwise the tendons will be rotten all of a sudden, and then it will be a big deal.

From this, it can be seen how precious this prescription produced by the system is, not only the scale is just right, but also specially improved Bi Fu's turtle body, which is more suitable for her cultivation.

While strengthening the muscles and veins, it can subtly enhance the strength of the body, and after years of use, Bi Fu's body may be able to go to the realm of invulnerability.

Bi Fu couldn't appreciate the magic of this prescription, and she clenched her back molars uncomfortably in the potion.

One moment it was like a burning sensation, and the other time it was as cold and biting as if it was in ice and snow, and the discomfort was not only on the surface of the skin, but also the medicinal power in the body was like a storm passing through, destroying the veins everywhere.

Under the action of the medicinal power, the muscles and veins are good and bad, and then they are restored when they are broken, and the cycle repeats.

Bi Fu gritted her teeth tightly, sweat falling down her forehead like a waterfall, thanks to her closed eyes, otherwise she would have gotten into her eyes.

Bi Fu's consciousness was all in controlling the power of the medicine and resisting the pain, and he had no energy to pay attention to the passage of time.

As the sun moved from east to west, and the full moon crept up the branches, the tormenting pain finally stopped.

The black liquid as ink also became clear, and Bi Fu's face was haggard, lying on the edge of the barrel with a tired face, losing the strength to move, and he looked a rare embarrassment.

But the complexion is good, the cheeks are flushed, after all, the body has received a lot of benefits, and this will be at its peak.

Her eyes were blurred and unfocused, her brain was buzzing, and a thick layer of black dirt had accumulated on her skin.

The smell of medicine in the bucket also disappeared, and what came out was the stench on Bi Fu's body, and the medicinal liquid removed some of the impurities in her body, although she was very stinky now, but she really didn't have the strength to clean it up.

Bi Fu simply put it in the bucket, and said it later, anyway, she was the only one who suffered from this stench.

"And me!" The system said angrily.

"The system has no sense of smell, don't lie to me, I'm tired, just bother you to suffer with me." Bi Fu didn't even move his eyelids, and replied lazily.

The system has rarely seen Bi Fu so embarrassed in the past few years, and can't help but gloat, "Yo, I can't stand it?" I can tell you, cultivating immortals, you have to suffer more than this, and it will be even more painful to forge in the future. ”

Although Bi Fu's physical strength was exhausted, his spirit was still good, and he said in a flat tone: "I know, I haven't imagined that cultivating immortals is a smooth path, but everything I do is for myself and to live." ”

At present, her strength is still too low, in order to live well, she has to improve her cultivation to a certain level in order to be safe, and she has to go back to the mortal realm to pick up Bi Xue, and she can't be bitter about anything!

"Is it okay to live?" The system asked coldly, the mechanical sound as good as ever.

"Of course, my life is gone, it's a fart to talk about anything, I just want to live." Bi Fu is straightforward, and if he cultivates, he can use it enough.

"I hope you remember this sentence and work hard for your own life in the future." The system's sudden serious attitude made a strange feeling flash in Bi Fu's heart.

"After all, you are so weak now, you will be used to make soup when you go out~~" Bi Fu didn't know how the mechanical voice made such a rippling and underwhelming tone.

It's rare that I just felt that the system was serious, and sure enough, seriousness is an illusion! Bi Fu complained silently.

Not bothering to pay attention to this yin and yang weird system, Bi Fu finally regained a little strength after resting in the bucket for a while.

Only then did he struggle to get out of the bucket and give himself a cleaning technique, removing the dirt and stench from his body.

After cleaning up the cave, I had time to feel the changes in my body.

Bi Fu summoned out the water mirror, compared to the weakness when she first cultivated, her eyes in the mirror were a little more resolute, and her body became stronger and more powerful, and her arms and legs had accumulated a layer of strong muscles due to long-term exercise.

She looked down at her hand that had not changed much on the outside, and as soon as her arm was forced, the muscles condensed into beautiful lines, and Bi Fu could feel the surging strength in her body at this time.

Bi Fu didn't use his spiritual power, he threw a punch forward, and the sound of breaking wind sounded in his ears, it was a more solid power than before soaking in the potion, in short, it was a qualitative change.

The tendons in the inner body have changed from a small plastic tube to a plastic tube with a large diameter and thickness, and this forging body can be said to be full of harvest!

Bi Fu nodded with great satisfaction, "It's worthy of the potion that cost me most of my wealth, it's really good." ”

The system sneered.

Bi Fu immediately said with a dog's leg: "Of course, the prescription provided by my dear system master is indispensable!" ”

The system snorted arrogantly.
