Dear Lingshi

Just as Lu Yunsheng was about to exchange these spiritual materials, his eyes were suddenly attracted by a sixth-level spiritual herb called Ice Feather Grass.

Looking at this rare ice-type spiritual herb, Lu Yunsheng suddenly wanted to come up with a better idea.

"It's time to change the flavor of the spirit wine." Lu Yunsheng looked at the Ice Feather Grass and a smile suddenly appeared on his face.

On Earth, he had drunk a lot of cold drinks. When he saw the ice feather grass, he immediately wanted to add it to his spirit wine.

This might result in a more novel-tasting spirit.

Thinking of this, in order to make the taste of the spiritual wine more colorful, Lu Yunsheng selected another natural treasure called Bingling Cleansing Marrow Dew from the Mountain and River List.

However, these two kinds of rare treasures are much more expensive than passion fruit. Lu Yunsheng silently calculated the proportion and found that he would spend 6,000 gold contribution points including these two kinds of rare treasures.

"It's OK to spend it. At worst the price will continue to go up." Lu Yunsheng thought so as he walked towards the disciple in charge of the exchange.

Unexpectedly, when Lu Yunsheng reported the treasures he needed to exchange, the disciple actually said that there were not so many spiritual grains in the sect.

Yes, this spiritual grain is of little use, and it is impossible for the sect to store 200,000 kilograms of it.

"How many sixth-level spiritual grains can be exchanged now?" Lu Yunsheng asked.

After checking it out, the disciple said, "There are only 150,000 jin now."

Lu Yunsheng nodded, and had no choice but to exchange all the 150,000 kilograms of spiritual grain.

Just as Lu Yunsheng accepted all the spiritual materials and was about to leave, the disciple suddenly said, "Brother, please come back tomorrow. A few days ago, a disciple has already received the task of purchasing spiritual grains and will probably be back tomorrow.

Hearing this, Lu Yunsheng was immediately delighted. He nodded and walked towards the door of the Deacon Hall.

Lu Yunsheng went straight back to the cave and immediately began to pack the spiritual grains into large wine jars. Last time, Lu Yunsheng bought a lot of wine jars in Xiaoyao City, so he didn't need to run again.

However, these hundreds of thousands of kilograms of spiritual grain need to be divided into hundreds of wine jars, so the space in the cave still seems a bit crowded after all.

There was no other choice, Lu Yunsheng planned to continue digging the cave and expand the space.

The fermentation of this spiritual wine is also strange. If the soaked spiritual grains are placed in the storage ring, it will not ferment. Lu Yunsheng has no choice but to put these wine jars in the cave.

Because of the restrictions in this cave, the temperature will not change throughout the year, so fermentation is extremely easy.

After expanding the cave, Lu Yunsheng spent another hour packing and soaking all the spiritual grains.

After practicing all night, Lu Yunsheng came to the Deacon Hall again the next day. After asking, he found out that Linggu had indeed returned to the sect.

After Lu Yunsheng exchanged 50,000 kilograms, he returned to the cave again.

In a blink of an eye, a month had passed, and the spiritual grain fermented by Lu Yunsheng had already begun to emit the aroma of wine.

The next step is to distill the wine.

As early as five days ago, Lu Yunsheng had finished his training and started to cut down spiritual trees in the uninhabited mountains around here to use as firewood for distillation.

Looking at the hundreds and thousands of wine jars that were as tall as a person, Lu Yunsheng felt overwhelmed.

This is easy to ferment but difficult to distill.

There is no shortcut in the distillation step, and he needs to distill it slowly, tank by tank.

Looking at the three large stoves he had built before, Lu Yunsheng prepared to build two more stoves. In this way, with five stoves working together for distillation, the speed could be greatly increased and he could take care of it all by himself.

He built the stove, put the pot on it, and lit the fire with spiritual wood. By the time Lu Yunsheng had placed all the utensils, the spiritual spring in the pot had begun to boil.

Lu Yunsheng immediately brought a jar of spiritual grain that exuded a strong aroma of wine and began to distill it.

Time passed in a flash and another half a month passed. On this day, Lu Yunsheng brought in the last jar of fermented spiritual grain and evenly divided it into five iron pots.

Not long after, crystal clear wine began to flow out of those drainage troughs.

It was noon, and seeing that the drainage trough was no longer producing wine, Lu Yunsheng immediately extinguished the firewood and put away all the utensils he used to make wine.

These things were related to the secret method of brewing wine, so Lu Yunsheng naturally had to keep them well. This time he was going on a long journey, so Lu Yunsheng even put all the five stoves and the remaining ashes into his storage ring.

After doing this, Lu Yunsheng took out the wine jug that Gong Yuanhuan gave him, and put all the spiritual wine brewed this time into it.

Probing with his spiritual sense, Lu Yunsheng looked at the 130,000 kilograms of sixth-grade spiritual wine in the wine jug and nodded with satisfaction.

This time, Lu Yunsheng exchanged a total of 250,000 kilograms of spiritual grains. Being able to brew so much spiritual wine was within his expectations.

However, this spiritual wine cannot be sold at this time. Before that, Lu Yunsheng has to refine the passion fruit, ice feather grass and other natural treasures he has exchanged, and then add them to the spiritual wine for seasoning.

After thinking for a moment, Lu Yunsheng took out a space spiritual device used to hold wine, and poured 30,000 kilograms of spiritual wine into it.

Lu Yunsheng planned to add the essence refined from passion fruit into the 30,000 kilograms, and for the 100,000 kilograms of spirit wine, Lu Yunsheng wanted to add the essence of ice feather grass and ice marrow cleansing dew.

Lu Yunsheng did it as he thought. He immediately took out the passion fruit and started to refine it. It was not until the next morning that Lu Yunsheng had mixed all the two different flavors of spirit wine.

Lu Yunsheng looked at his work with satisfaction, and couldn't wait to take a small ball of the cold spiritual wine from the wine jug.

When swallowing the spiritual wine, Lu Yunsheng's eyes suddenly lit up. He felt as if he had a piece of ice in his mouth, and a cool feeling immediately spread from his mouth to his whole body.

The coolness did not last long, probably only half a breath, and then a hot current suddenly rushed to his forehead.

This kind of ice and fire stimulation did not last for a short time, but appeared repeatedly in his mouth three or four times before slowly subsiding.

"Great! So great!" After swallowing the spirit wine reluctantly, Lu Yunsheng exclaimed loudly. At this moment, he even admired himself for being able to brew such wonderful spirit wine.

Lu Yunsheng smiled, and while smiling happily, he put away the wine jug.

"That's right! Let's call this wine Bing Xin!" Lu Yunsheng smiled and gave this spiritual wine a nice and appropriate name.

After picking the name, Lu Yunsheng prepared to send the spirit wine to the Deacon Hall, and then go directly to the Weapon Refining Sect.

In Tongtian Sword Sect, there are not too many requirements for the discipline of disciples, and they do not need to report to anyone if they want to leave the sect for a long time.
