Sun Li's eyes flickered slightly, and he carefully folded the fragment in his hand, stuffed it into his arms, and put it close to his body. He stooped down again, picked up the books that were scattered on the ground, and put them back in their place.

After that, Sun Li began to sit on the side and began to be in a daze, or to think.

This process lasted for a long time, so long that a new stick of incense could be burned from beginning to end, and Sun Li had another movement. Sun Li slowly got up and stood up from the stone bench mountain, his eyes became a little solemn, some bright, and some resolute.

It's as if a crucial decision has been made on something big.

Then Sun Li walked to the side expressionlessly, picked up the book he had put down just now, opened it, spoke aloud, and recited it......

Back!

Back!

Back!

Sun Li began to recite, reciting with a completely different attitude than before. If it used to be a hard and hard back, but now it is a crazy and desperate back.

The back, the constant back, the back of the waste sleep and forgetting to eat, the back of the head cantilevered by the cone and the thorn strands.

Then, five days later, the gray-haired old man appeared on time.

The footsteps sounded, and the gray-haired old man walked into the cave with steady steps, looked at Sun Li, whose eyes were red, and a trace of discoloration flashed in his eyes, and then returned to normal, and then asked: "What is the seventh chapter and eighth verse of the Funan Medicine Sutra about?"

"Yin and yang are mutually reinforcing, solitary yin is not long, only yang is not born, yin and yang are mutually beneficial, and only then can they become medicines. Yin and yang neutralize the middle, and the medicinal properties are peaceful. It can be used for minor illnesses, slowly drawing it, slowly healing, and can be used for ......" Sun Li's voice was a little hoarse.

"The thirty-third chapter of "Xu Zhuo's Theory of Medicine"?"

"Treasures. The earthly nourishing things, absorbing the essence of heaven and earth, the glory of the sun and the moon, after thousands of years, can become a great medicine, the name of the heavenly treasure......"

"The second part of the "Armillary Pharmacopoeia" ......"

"Orderly ...... in the Miscellaneous Medicinal Properties"

“......”

“......”

The whole question and answer lasted longer than the last time, and it didn't end until the time when the three incense sticks were burned, and the old man looked at Sun Li with some appreciation. After that, the old man walked to the bookshelf on the side, took out more than a dozen thicker books, and handed them to Sun Li, "These are relatively advanced knowledge in alchemy, you memorize them, and I will check them in seven days." ”

As he spoke, the old man turned around and walked towards the outside of the capital again.

And at this time, Sun Li suddenly spoke, "Elder, no need. ”

"Huh?" the gray-haired old man turned back to him with some doubts, "No need?"

"Yes, no. Sun Li said seriously.

"What, don't you want to recite it?" The gray-haired old man's gaze was a little cold, making Sun Li involuntarily sound what the white-robed old man had said before.

Either dead or disabled, the rest are crazy!

But Sun Li didn't have any fear, and just said in a deep voice to the gray-haired old man: "It's not that I don't want to memorize." ”

"That's?"

"It's the disciple who has already memorized it. ”

"Huh?" the gray-haired old man was visibly stunned, his brows slowly furrowed, and the more he wrinkled, the tighter he became, "You said, you have memorized these books?"

"Yes. In the past five days, the disciple had memorized these dozen books. ”

"Okay, let me ask you what is the ninth chapter of "The Treatise on the Cold"?"

"The weather is cold and hot, it is winter and summer in the four seasons, winter is slaughtering, it is suitable for warm maintenance, summer is luxuriant, and it is suitable for hair growth......"

"The general preface of the Heavenly Mystery Sutra?"

"All things are born to feed people......"

"The Ninth Chapter of the Water Fu Difficult Sutra ......"

"There is no ninth. ”

"What about the sixth?"

"The good is like water, and the water is yin to the soft thing, which is applied to pharmacology and ...... for it"

Another half an hour passed, and the old man stopped asking, but his gaze changed a little when he looked at Sun Li, "These are really what you memorized in the previous five days." ”

"Don't dare to deceive the elders, these are indeed the ones that the disciple has recited in the previous five days. ”

"It seems that you have put your heart into it. ”

"Don't dare, the disciple instructed that he hoped to learn more alchemy. Sun Li looked at the gray-haired old man and said sincerely.

"Then ......" The old man looked at Sun Li's gaze, and said slowly after a long time, "Then, you can start learning alchemy today." ”

"Yes. ”

"Then I'll teach you how to refine the Heavenly Fragrance Blood Activating Pill first, which is the one that you were asked to refine during the previous third level test. Before, what you refined was only with the help of the effect of Zhu Guo to achieve amazing medicinal effects, but now I want you to refine the Tianxiang Blood Activating Pill with at least ninety percent medicinal effect without the help of foreign objects. ”

"Yes. Sun Li replied as simply as ever.

The gray-haired old man nodded slightly, directly opened the medicine tripod, and carried out a new pill refining. While refining, he said, "Remember, I will only give you seven days, and if you can't meet the requirements by then......"

"The disciple will work hard, please rest assured. Sun Li suddenly interrupted the old man's words.

The old man looked over, his eyes flashing slightly, "Let's talk about it when you do it." As he spoke, the gray-haired old man threw the processed medicinal materials one after another towards the medicine pod.

The fire is rising, and the heat is spreading......

And then a day later.

The medicine pod had cooled down, and the temperature in the cave had dropped to a normal level, but inside the cave, the gray-haired old man was holding a Tianxiang Blood Activating Pill with eighty percent medicinal effect and staring at it for a long time.

"Is this really what you refined yourself?" the old man finally asked.

"Yes, this is indeed what the disciple refined last night, but it is still a little short of the elder's request. Sun Li said expressionlessly.

"It's not even close. The old man muttered, then shook his head and walked towards the outside of the cave, saying as he walked: "Then let's refine a few more dings, and wait until the effect of the medicine reaches ninety percent." ”

"Yes. ”

Then two days later.

The gray-haired old man who reappeared in the cave was silent for a long time with an almost perfect Tianxiang Blood Activating Pill, and after a long time, he suddenly said without a head, "You are not much different from him seven years ago." ”

"He?" Sun Li asked.

But the gray-haired old man didn't answer at all, just turned his head to look, and then said: "Since you can already refine the Tianxiang Blood Activating Pill so well, then let's learn the next elixir, Qinglian Jingxin Pill, and look at it......"

Saying this, the largest medicine pod in the cave became hot again, and countless medicinal herbs fell into it, and the medicinal fragrance overflowed.

The old man had refined it twice in total, and after confirming that Sun Li understood every step, he left the cave again.

And overnight, the slightly smaller pod in the cave has not cooled.

The next day, the gray-haired old man who returned to the cave got the freshly baked Qinglian Tranquility Pill with seventy percent medicinal effect.

On the third day, the medicinal effect of the Qinglian Jingxin Pill reached ninety percent.

On the fourth day, what the gray-haired old man saw was the perfectly refined Qinglian Meditation Pill.

Then on the seventh day, it was still a perfectly refined elixir, but the Qinglian Tranquility Pill became the Snow Lotus Heart Protection Pill.

On the tenth day, it was the Five Flowers Guiyuan Pill.

On the twelfth day, ** Jade Toad Pill.

Then there are the Seven Treasure Replenishing Spirit Pill, the Eight Noble Purple Fire Pills, and the Jiuhua Yulu Pill......

This situation lasted until the thirty-seventh day, when Sun Li handed over a perfectly refined white jade pulp cleansing pill to the gray-haired old man, the gray-haired old man spoke, "You have learned the refining of all the pills. ”

"The disciple still wants to learn again. ”

"Do you know what's up there?"

"What is it?"

"Dan pill pill, above the medicine is Dan. Dan is the ancestor of medicine, and it is also the ancestor of medicine. If you want to learn, what you want to learn is no longer alchemy, but alchemy. ”

"The disciple wants to learn, and he hopes that the elders will allow it. Sun Li said seriously.

"I can teach you. The old man said lightly, and then his tone changed, "But you can't learn." ”
