The next day, just as Lin Yanli expected, Wang Zhenchuan came to the door.
After talking to Lin Yanli for a while, he left with awe in his face. He was obviously impressed by Lin Yanli.
After taking care of the affairs of the small fishing village, Lin Yanli seemed to have some free time, wandering around the Thousand Demons Sect with his hands behind his back all day long.
At this time, good news finally came from the Shifang Mountains.
In a canyon 1,800 miles away from the Thousand Demons Sect, disciples of the Thousand Demons Sect discovered a spiritual stone mine, and it seemed that the reserves were quite high.
For the Thousand Demons Sect, which owes a huge debt, this is undoubtedly a timely help.
"The problem now is that the spiritual mine is located under the Sanling Rock. It is difficult for non-three-level monks to dig it. Half of our third-level monks from Thousand Demons Sect are outside. If we deploy a large number of disciples to excavate the rock and soil, other places will have to slow down.
.”
The second elder handed the roster to Lin Yanli. After Lin Yanli looked through it carefully, he became confused for a moment.
The monks of the Third Realm are so slow, it is impossible to let them do it separately. Thousand Demons Sect is a sect that knows how to combine work and rest. If the work is too tiring, the disciples will rebel!
"Where's Yanyun Pavilion? Can't they allocate some manpower to us?"
The second elder gave a wry smile, shook his head slightly and said: "Something happened in Yanyun Pavilion in Mubei a few days ago, and now we can't find any manpower. This matter can only be handled by our Thousand Demon Sect!"
Lin Yanli raised her hand and nodded, this matter was indeed a bit difficult to handle.
The scattered spirit rock will absorb the spiritual energy of the monks, making it impossible to use the spiritual energy and spells. Low-level practitioners without the blessing of spiritual energy have the same strength as ordinary people. Only the monks of the Zifu period who have reshaped their bodies can dig the hard scattered spirit rock.
How long can you dig with brute force?
Lin Yanli rolled her eyes and thought of a good idea.
"You go and do other things first, put this matter aside for now."
"Yes, please make a decision as soon as possible, Master!"
After the second elder slowly exited the hall, Lin Yanli thought for a moment and then called over some old ladies who were in charge of logistics.
"Help me prepare sulfur, saltpeter, and pigskin. The more the better!"
The old ladies looked at each other, wondering what Lin Yanli wanted with these things.
Lin Yanli seemed to have reacted. He took out a jade slip from his sleeve and kept it in the old nanny's hand. "Prepare all the above things for me. I will be of great use!"
The old grandma nodded, and after exiting the hall, she opened the jade slip and took a closer look.
(Plant ash, rotten eggs, saltpeter, charcoal...)
The old grandma scratched her head, not knowing what Lin Yanli wanted these things for.
But she still made preparations according to Lin Yanli's instructions.
Lin Yanli found an open space on Lihe Mountain and placed the storage bags one by one.
People in this world have a shortcoming.
The world of immortality is too separate from the secular world.
Ordinary people imagine that practitioners are too mysterious, and practitioners treat ordinary people with too much contempt.
Lin Yanli wants to use a practitioner's ability and mortal wisdom to dig out the spiritual mine buried deep under the Sanling Rock.
Gunpowder is not uncommon in this world, and you can often see people setting off fireworks and firecrackers in the secular world.
But Lin Yanli did not want to make black powder, but a powerful nitroglycerin explosive.
Lin Yanli can refine elixirs herself, and is very comfortable with the use of spiritual energy. For her, preparing explosives is only a little more cumbersome than refining elixirs.
"Glycerin, nitric acid, sulfuric acid... Let's start with glycerin!"
Lin Yanli took out the pig skin from the storage bag and threw it on the ground.
Then he ran to the kitchen and asked for a big iron bucket.
Lin Yanli used a powerful move to condense the pig skin into lard using elixir fire.
Several disciples stepped on their swords and threw several huge stones on the ground. These were the marbles ordered by Lin Yanli.
Lin Yanli raised his finger and twisted the marble into powder, then refined it into hydrated lime, and then mixed it with soda ash to refine it into caustic soda.
Several disciples were surprised and stayed at the top of the mountain for a while, wondering what Lin Yanli was refining.
After finishing all this, Lin Yanli poured the hot lard into the iron bucket and poured in the resulting caustic soda.
"Well, come here and help me stir!" Lin Yanli raised his finger on the male disciple and called him over.
These people had been watching here for a long time. Since they had nothing to do, Lin Yanli helped them find something to do.
Several disciples were also happy to help Lin Yanli. They ran forward happily, took the wooden stick from Lin Yanli's hand and stirred it in the bucket vigorously.
Waiting until the lard cooled down, several disciples finally reacted.
"Master, are you making saponins?"
"It seems like, you see, the lump underneath is indeed soap locust."
"It's amazing. The master of the sect is so knowledgeable that he even knows how to make such small things."
Several people praised Lin Yanli. When they were about to pour out the scum floating on the iron bucket, Lin Yanli gave each of them a mallet.
Lin Yanli separated the wastewater from the soap, then used spiritual energy to compress the wastewater into a ball, and used elixir fire to refine the impurities inside. She obtained the purest glycerin.
For practitioners who know how to refine elixirs, separation and purification is the simplest task.
Jiang Wanli has been refining elixirs for hundreds of years, and controls the elixir fire as if it were his own fingers. Although Lin Yanli is still low in cultivation, combined with the knowledge from his previous life, he knows how to control spiritual energy better than Jiang Wanli did during his time.
.
After refining the glycerin, Lin Yanli took out the saltpeter from the storage bag.
Refining nitroglycerin requires nitric acid and sulfuric acid. It is very easy to obtain these two things. Using the gas of saltpeter and rotten eggs, and borrowing some magic techniques, Lin Yanli easily put the obtained sulfuric acid and nitric acid into the porcelain bottle.
In this world that does not follow the laws of physics, Lin Yanli successfully integrated alchemy, spiritual practice, and chemistry.
Next, is the most important step.
Lin Yanli swallowed, took out a defensive spiritual treasure from the storage bag, and then wrapped her whole body with protective spiritual energy. She carefully mixed glycerin, nitric acid, and sulfuric acid together.
She released her consciousness to ensure that everything was mixed evenly. In order to strengthen the stability of the nitroglycerin, Lin Yanli specially constructed a formation to absorb the temperature generated in the reaction.
After a while of burning incense, Lin Yanli led several disciples to the cliff of Blood Demon Mountain. She carefully placed the porcelain vase on a piece of bluestone and hid far away.
She handed the defensive spirit treasure in her hand to the disciple beside her and whispered: "Wrap the protective spirit around yourself and use the spiritual energy to crush the porcelain bottle."
The disciple nodded and ran forward curiously. He looked back at the nervous Lin Yanli, feeling strange in his heart.
With such a gadget and a protective aura activated, wouldn't it make his cultivation base seem very low?
Just fight hard and that's it.
While Lin Yanli was stunned, the disciple ran forward and summoned up his spiritual energy to smash the porcelain bottle into pieces.
The next second, a wave of air rose into the sky. Lin Yanli was startled and quickly covered his ears.
"boom!!"
A deafening explosion sounded, dust filled the air, and smoke flew everywhere.
Lin Yanli hid behind the stone and looked up, watching the disciples beside him being overturned by the air waves, and couldn't help but open his mouth.
