However, after each refining, Li Qing would sum up his experience and find his own shortcomings to improve. As a result, with the increase in the number of times, Li Qing's refining techniques became more and more skillful and stable.

By the time of the seventh furnace, Cheng Dan had basically stabilized between six and nine grains. Moreover, the quality of the pill has also been greatly improved, maintaining it around the level of normal pill quality.

By the time of the tenth furnace, Li Qing had even refined ten Qi Gathering Pills at one time, and the quality was above the horizontal line.

However, just as Li Qing was preparing to refine the eleventh furnace Qi Gathering Pill, the door of the alchemy room was opened. The sunset outside the house shone in, and at the same time, Huang Lao's shadow was cast on Li Qing.

"Huang Lao?" The change in light made Li Qing a little dazed, and he blinked and said in surprise.

Huang Lao came in meant that the agreed time had arrived, but Li Qing didn't feel the passage of time because he was concentrating on refining the Qi Gathering Pill, so he was a little surprised after Huang Lao pushed the door in.

"How?" Huang Lao slowly walked into the alchemy room, looked at the pile of jade boxes on the ground, and asked with a few porcelain bottles.

"Uh...... Not ideal! Ten materials succeeded eight times and failed twice. In the end, less than forty Qi Gathering Pills were refined. Li Qing sat on the ground and didn't get up, but his tone was slightly embarrassed.

Huang Lao didn't say anything when he heard this, but stretched out his hand and took a few porcelain bottles into his hand. Open one of the porcelain bottles and pour the pills inside into the palm of your hand to look at it. "The residue is not well separated, and the impurities are too high."

Huang Lao did not stop, but continued to open the porcelain bottle and pour out the pills inside. "The firepower of the treatment of Rehmannia essence is too strong, the medicinal power of the Dan is uneven, and the time of receiving the Dan is too early............"

In Huang Lao's eyes, he could naturally see the quality of these pills and what step he went wrong, and even any mistakes he made could be seen through the appearance of the pills, so every time he poured out the Qi Gathering Pill in a porcelain bottle, he commented mercilessly.

Li Qing could only bow his head and listen to Huang Lao's comments that poked at the pain points, but Li Qing did not feel that this was accusation, but on the contrary, Huang Lao pointed out his shortcomings in this way and wanted to learn a lesson from it.

After Huang Lao commented, he pointed out the key points of Li Qing's refining of the Qi Gathering Pill, and Li Qing accepted them one by one and memorized them firmly.

"Alright, since you used so many materials and failed to complete the task I gave you. Then continue to refine the Qi Gathering Pill from tomorrow until it is repaid. Huang Lao made a final decision, and finally threw back a porcelain bottle to Li Qingdao with great disgust. These can't even meet the minimum quality requirements, take me don't want to! ”

"Remember, you still owe me ninety Qi Gathering Pills." Huang Lao said seriously.

"Yes." Li Qing responded weakly when he heard this.

At this time, the state of excitement during alchemy disappeared, and he felt extremely tired physically and mentally. There is also a huge "debt" pressing on the body, and the powerlessness to resist.

…………

Li Qing immediately rushed back to Xiao Qianfeng's way back to Medicine Valley, and at this time, the sky had already darkened.

In order not to crash into the mountain because he couldn't see things clearly in high-speed flight, Li Qing could only brave the cold wind at night to raise the flight altitude. "Didn't Elder Huang say that he would call me before the sun went down? It's all at this time. ”

Looking at the moon hanging high in the sky, Li Qing was a little helpless, he didn't expect to go back so late.

However, what Li Qing didn't know was that when he was refining the tenth furnace of Qi Gathering Pill, Huang Lao was already outside the door of the alchemy room, quietly watching him finish refining the tenth furnace.

Li Qing accelerated his flight, he just wanted to go back to the cave for a night's rest now.

However, when he approached the cave, he almost fell from the Liuyun Sword.

Because Li Qing saw a familiar figure outside the cave, although Li Qing had seen each other three times in total, he had already firmly remembered the other party's face.

That's right, He Renlin, who appeared outside his cave mansion in the morning, He Er.

"Why is he still here!" Li Qing was suspicious and surprised in his heart, feeling the other party's perseverance and at the same time having a headache.

He finally felt what He Er meant now, Tai Er or too stubborn.

And this way is so fresh and refined, unique.

However, a headache is a headache, Li Qing is going to return to the cave after all, so he can only bite the bullet and fall slowly.

"Li ......"

"Oh, Senior Brother He! Why are you still here at such a late hour? But I'm sorry, I'm too tired today to entertain Senior Brother He! ”

When He Renlin saw Li Qing coming back, Gujing Wubo's eyes immediately found focus, but before he could speak, he was blocked by Li Qing.

Then he heard the sound of the door closing, and when he reacted, Li Qing had already entered the cave.

Li ...... Green! He Renlin's facial expression was distorted, and his hands were clenched. There was an evil fire in his chest that could not be vented.

However, after a few breaths, He Renlin's face collapsed again, although he was angry at Li Qing's evasion, but at the same time he was an extremely reasonable and reasonable person, of course, this reason must be the reason he recognized.

And just now, Li Qing was indeed tired and depressed. This cannot be faked, he can see.

Although he made an appointment with Li Qing, he boasted that he never took advantage of others' danger.

"And forgive you this time!" He Renlin pointed to the empty gate of the cave and said softly. I don't know who gave it to whom.

Then he turned away angrily.

Li Qing's ears were attached to the gate of the cave, and he was relieved when he heard the footsteps outside walking farther and farther.

This He Er is simply too stubborn, and he is still squatting in front of his cave mansion so late.

I don't know what the other party thinks?

However, although this He Er is a little difficult and stubborn, it is good not to make small moves behind his back.

And it's a little tricky, it's difficult but not arrogant. That's a bit peculiar.

Li Qing shook his head and returned to the cave to rest, he felt that after this incident, He Renlin should give up.

However, Li Qing still thought that this matter was too simple, or that He Renlin was too simple.

Early in the morning of the second day, Li Qing left the cave mansion and prepared to go to Yaogu Huang Lao to continue to repay the "debt".

However, as soon as he opened the door of the cave, he saw He Renlin standing there staring at the dew.

"Hiss......" Li Qing couldn't help but gasp, and said with some uncertainty. Senior Brother He, didn't you go back last night? How to ......"

"I did go back, but I came again early this morning!" He Renlin looked at Li Qing and said expressionlessly.

"Uh...... I feel like you have a point! Li Qing was a little speechless when he heard this, so he had to cross the other party and plan to leave.

"Wait!"

But just as Li Qing took a step, a hand stretched out to stop him.

"You don't want to make excuses to leave, do you?" He Renlin said with an indignant face.

"What excuses?" Li Qing deliberately pretended to be stupid and said, he found that if he wanted to get rid of He Er's entanglement, the best thing was to act as if he didn't know the other party's purpose.

"I made an appointment with you to decide the ownership of this cave, why do you keep dodging?" He Renlin asked in a raised tone.
