After all the aura was infused, its floating figure became illusory again, flew back into the old man's heavenly spirit, and disappeared in the overlap with his body.

At this moment, the Dan stove flashed with green light, and the Dan fragrance overflowed. At the same time, the old man pinched the trick again and pointed at his hand, and suddenly a terrifying aura emanated, and this breath contained a feeling that made the whole body numb.

"It's thunder!"

In Lin Sen's incredible look, under the old man's finger, a purple lightning bolt immediately rushed out, directly hitting the Dan furnace, the Dan furnace shattered, and a cyan pill-sized cyan pill appeared.

"Seven Rank Azure Pill!"

The old man was slightly tired, looked at the green elixir in front of him, and smiled.

At this moment, Lin Sen could hardly believe his ears, this old man was actually refining the seven-grade pill, not the six-grade as Lin Sen guessed!

"Little baby, you're here!" The old man looked at Lin Sen, although he felt that Lin Sen's appearance at the moment was completely different, but his aura did not change at all.

"Junior, I'm disturbed!" Lin Sen's expression became more and more respectful, and he suddenly discovered that this person's alchemy technique was even above Guang Jizi, and he was most likely one of the only three thunder attribute seniors in the Dan Holy Sect.

The sloppy old man looked at Lin Sen meaningfully, and he put away the Azure Pill. He smiled and said, "A few days ago, the old man was busy refining the Azure Pill, and he had no time to take care of what was happening outside. I originally thought that you would die, but I didn't expect that your kid is not small, and he actually didn't die under the blow of Jiang Cheng's little baby, which is really a creation. ”

Lin Sen's heart moved, but he didn't expect the scene of that day, all the old men saw it. At the same time, he secretly wrote down the name Jiang Cheng, this person almost took his own life, and Lin Sen would not let go of anyone who provoked him.

"The seniors laughed, and the juniors were really lucky. ”

The old man didn't say much about this matter anymore, but muttered: "Pills, it's not you who refine them like that! Kong Ming's kid's Cultivation Pill Dao can indeed be regarded as a method, but the old man asserted that it is difficult for his alchemy to improve in this life, and he can only refine the five-grade elixir, as for refining the six-grade elixir, it is a fluke." ”

Then, he said: "Li Ji's Fire Control Pill Dao, although it has grasped the key point of Cheng Dan, can only refine inferior pills of the same quality, and it is not a perfect way of alchemy. You are confused in the methods of these two people, and naturally you can't refine it. Fortunately, you found the old man, otherwise, your alchemy path would have come to an end. ”

When Lin Sen heard this, he immediately bowed respectfully and said, "Please ask the seniors for advice!"

The sloppy old man stroked his gray beard and said with a smile: "Little baby, you have seen the process of the old man's alchemy, this is the way of the old man's alchemy, the way of sacrificing the pill!"

"In the old man's understanding, refining pills is the same as cultivating, it is a matter against the sky, which explains why when some seventh-grade high-grade pills or even eighth-grade pills are refined, there will be visions of heaven and earth, and even lead to thunderstorms. If the pill is refined in the form of sacrifices, it can be done in accordance with the way of heaven rather than against the sky, and in the dark, free heavenly fortune is blessed, and the probability of success in alchemy is naturally extremely high. And the sacrifice mentioned here is just an elixir. The old man said slowly.

Lin Sen seemed to have an understanding, and he immediately asked: "If you refine the pill with the sacrificial pill Dao, is the sacrifice required to determine the quality of the pill, for example, to refine the third-grade pill, you need four second-grade pills as a sacrifice to refine it?"

The old man's eyes flashed, and he suddenly smiled and said: "Yes, this sacrifice pill is also divided into time periods, and the old man will tell you about this in detail."

In this way, Lin Sen listened carefully to the old man's explanation, and unconsciously passed a day.

"Little baby, the old man told you so much, do you remember everything?" said the old man yawning.

"The juniors remember, thank you for your advice!"

"The old man saw that you are talented and intelligent, and you have a strong understanding, which is much stronger than those little cubs of the Dan Holy Sect. After that, the old man yawned again, looking drowsy, and finally, he patted the Qiankun bag, took out a shabby gourd, and handed it to Lin Sen, as for what he said in the end, Lin Sen didn't hear a word clearly.

Lin Sen took the gourd with a strange expression, this gourd was obviously used by the old man to hold wine.

"Do you want me to help him get wine?" Lin Sen groaned slightly, and then shook the gourd, and there was a little liquid in it. Curiously, he pulled out the cork, and put his nose close to the mouth of the gourd to smell it, but there was not a trace of wine coming out of it, but there was a clear smell of earth.

He muttered a little, a smell similar to that emanating from the cave, and after a moment, his eyes flashed, and he suddenly looked up at the upside-down goblin stalagmite on the top of the cave.

"Could it be that the liquid in this gourd is the goblin bamboo shoot liquid!" Lin Sen put away the gourd, bowed deeply to the old man, and turned to leave.

Back at his residence, Lin Sen did not immediately refine the third-grade Zhuji Dan, but refined the second-grade pill.

As time passed, half a month passed quickly. Lin Sen took a total of three pills, including the previous two, a total of five pills.

Lin Sen's cultivation also grew rapidly during this time, and soon reached the peak of the early Yuan Dan, only one line away from the middle Yuan Dan. But the effect of the Continuation Pill is getting lower and lower, and Lin Sen does not plan to continue to take it, but to go all out to refine the pill.

In half a month, Lin Sen refined a total of 100 second-grade Naling pills. Many of them are nine pills in one furnace, so that so many pills can be refined in a very short period of time.

"Since we want to refine the pill with the sacrificial pill path, then the pill sacrifice is naturally indispensable. At this moment, Lin Sen took a deep breath and planned to try to refine the Sanpin Zhuji Dan again. After all the herbs of the Dan Furnace were ready, Lin Sen meditated cross-legged according to the method explained by the old man, quietly waiting for the best time for alchemy.

A quarter of an hour later, Lin Sen woke up from his meditation, he controlled the fire beads in his body, and with a sudden finger of his hands, a scorching flame burst out and appeared under the Dan furnace, and the temperature immediately increased.

Immediately afterwards, Lin Sen threw herbs into the Dan furnace and began refining. Everything is under Lin Sen's control.

Until the evening of the next day, when a pale yellow smoke cloud floated out of the Dan furnace, Lin Sen pinched his fingers, and the smoke cloud immediately turned into a huge palm and spread out.

Immediately after, Lin Sen threw the prepared four second-grade Naling pills towards Yanyun's palm, and the pill was immediately put into the Dan furnace, and all this went smoothly according to the old man's method.

Soon after, a strong scent of Dan wafted from Lin Sen's residence. I saw Lin Sen's eyes showing excitement, looking at a pale yellow pill in his hand, and cherished it in the jade box that had been prepared a long time ago.

This time, he finally succeeded! Lin Sen, from the beginning to the refining of the third-grade pill, it took less than a year, which far exceeded the task set by Guang Jizi to refine the second-grade pill within two years.
