Five kinds of medicine in another world

Hearing Li Qiufeng say this, Gu Shijiu couldn't help but ask curiously:

"Oh? What kind of treasure is it that is causing you this trouble?"

Li Qiufeng shook his head and said helplessly:

"I don't know the specifics, but every time I use it, I will suffer a certain amount of backlash. I can't use it, but I think this treasure is destined for you. If I can unravel the mystery, it may be helpful to you."

Gu Shijiu was moved after hearing this. Since Li Qiufeng valued it so much, it must not be an ordinary thing. He nodded and replied:

"Okay, let's go and have a look."

Seeing that Gu Shijiu agreed, Li Qiufeng also smiled and said:

"I hope you can master that treasure. It's my magic spell, and I haven't gotten the key to it in hundreds of years. It's a waste of my time to practice."

As he said that, he took Gu Shijiu in that direction. Along the way, the two chatted in a relaxed and harmonious atmosphere.

The two men walked to a secret room. Li Qiufeng stepped forward and fiddled with it for a few times. The door opened, revealing the space inside.

The space inside was very simple, with nothing furnished except a single cushion and a broken knife.

Li Qiufeng walked in first, pointing at the broken knife on the ground and said:

"Nineteen, this is the legendary treasure that can defeat a ninth-level warrior with an eighth-level late-stage one. My father Li Hengdao got it by chance. Later, he fought hundreds of rounds with an early-stage celestial immortal and was slightly at a disadvantage. However, the price of this sword is also very shocking."

Li Qiufeng paused and continued:

"The price of this knife is life. Use it once and you will have to pay for a thousand years of life!"

Li Qiufeng sighed: "So, although this treasure is powerful, it is a double-edged sword. No one would use it easily unless they have no other choice."

Gu Shijiu nodded slightly to show his understanding.

He knew that such a powerful treasure must come with a huge price. But for Li Hengdao, this sword might be his last hope when facing a strong enemy.

However, the price of this knife is so heavy that one can't help but sigh at the fickleness of fate.

Gu Shijiu still stood there calmly. He already had some guesses in his heart. After all, how could such a heaven-defying treasure be without a price? And how could the price be light?

Moreover, he knew clearly in his heart that his life span was definitely different from that of others.

After all, he had taken the potion codenamed Shou. This knife was a double-edged sword for others, but not necessarily for him.

Of course, he kept these thoughts deep in his heart and did not express them.

Gu Shijiuwan slowly squatted on the ground and picked up the broken knife with his right hand. After just a moment, Gu Shijiu felt a stream of attraction constantly coming out of the knife, as if it was absorbing something.

Gu Shijiu looked at Candao and Li Qiufeng, frowned, and asked softly:

"Is the way to make it recognize its master to continuously provide it with lifespan for it to absorb? If that's the case, I definitely can't afford it!"

Li Qiufeng shook his head, indicating that it was both right and wrong. He explained that if the energy of the thousand-year-old tree heart was used to replace the life span, the master recognition could be completed, but the process would be very long and require a lot of energy.

Li Qiufeng glanced at Gu Shijiu guiltily, and then continued:

"My father was lucky enough to get a thousand-year-old tree heart, which allowed him to successfully make this broken sword his master. But even so, every time he used the broken sword, he still had to pay a thousand years of his life as a price. So, my father had no choice but to go out and look for a new treasure to get rid of the shackles of the broken sword."

Gu Shijiu nodded after hearing this, his face becoming very solemn. He stared at the broken knife quietly, lost in thought, and said nothing.

"Nineteen, I still have two thousand-year-old tree hearts and half a three-thousand-year-old tree heart. These are my stocks. I really can't establish a connection with it, otherwise I would have come here by myself. These things are left to you. If you have a chance, try them. If you don't have a chance, it's my apology to you."

Li Qiufeng took out three pieces of tree heart from the space ring with a wry smile and handed them to Gu Shijiu.

Gu Shijiu originally planned to give it a try, but he didn't expect to get an unexpected reward. Gu Shijiu smiled and said:

"Thank you very much, Grand Elder Qiu Feng. I'll give it a try. If it doesn't work, we'll talk later."

Li Qiufeng also smiled and said:

"Then I wish Brother Nineteen to gain Candao's recognition soon and become the pillar of our Hengdao Escort Agency."

Gu Shijiu smiled and waved his hand, and Li Qiufeng retreated, considerately closing the door.

Qinglong emerged from the soul seal and looked at the broken sword and couldn't help but sigh:

"This is the broken sword in Li Hengdao's hand back then. It is indeed an evil weapon. Nineteen, try to use this thing as little as possible. What Li Qiufeng said just now is not complete."

"Senior Qinglong? Do you know this broken sword?"

Gu Shijiu asked curiously.

"Of course I know. The broken sword in Li Hengdao's hand is also very famous. Everyone in his time knows about this evil weapon. By the way, do you know how long Li Hengdao can live?"

Qinglong suddenly changed his mind and asked.

"I don't know, but an eighth-level saint has a lifespan of 100,000 years, so I guess it's still early for Senior Li Hengdao."

Gu Shijiu thought for a moment and replied.

"Wrong, wrong, wrong."

Qinglong smiled bitterly and shook his head:

"It's true that an eighth-level saint can live for 100,000 years. Li Hengdao, who is in the late eighth level, may even live for 700,000 or 800,000 years. But because of this broken sword, Li Hengdao used it too frequently, which greatly reduced his lifespan. If Li Hengdao hadn't used many treasures to prolong his life, he would have died long ago."

"No way?"

Gu Shijiu continued to ask with some doubt:

"How can a life span of hundreds of thousands of years be used up so quickly? One time is equivalent to a thousand years of life. Did he use it up hundreds of times? It's unscientific!"

After hearing what Gu Shijiu said, Qinglong was somewhat puzzled:

"What science? Let me tell you, the most basic way to use the evil sword is to extend your lifespan by a thousand years with one strike. This strike will double the power, but this is just the beginning."

"Begin? You mean there are other uses?"

Gu Shijiu understood a little and asked.

"Yes, this evil sword has three uses. The first is to use a sword that can last for a thousand years, and its power will double. A late eighth-level warrior can reach the strength of a pseudo ninth-level warrior. The second is to use a sword that can last for ten thousand years, and its power will increase fivefold. A late eighth-level warrior can reach the strength of an early ninth-level warrior. The third is to use a sword that can last for a hundred thousand years, and its power will increase tenfold. A late eighth-level warrior can reach the strength of a mid-ninth-level warrior. These are the three uses of the evil sword."

"And the reason why Li Hengdao is dying is because he has used this broken sword several times in the third use. One strike can take a hundred thousand years of life, and he can't bear it anymore."

After Qinglong finished speaking, Gu Shijiu stood there in a daze, not daring to imagine.

One sword can extend one's lifespan by 100,000 years. Even if he has a potion codenamed "longevity", he would not dare to try it easily. Thinking of this, Gu Shijiu looked at the broken sword in his hand with a complicated expression.
