Li Jiwan went to Xichang Teahouse to find San Uncle and collected a lot of spirit stones. His next plan was to buy a large number of utensils. It was not enough to rely on his little spirit stones alone.

If a low-level cultivator in the consecration realm wants to cause some trouble for a cultivation family or even a top sect, what should he do? He doesn't know what others will do. Anyway, as a time traveler, he really can't think of any other way besides the powerful explosive weapons in his previous life.

On the seventh day of the ninth month, there are 53 days left. The Li clan will worship his ancestors on the rooftop terrace of Longtou Mountain, more than 20 miles outside Xuanyuan City. The time is very clear, this is the ancestral system, and filial sons and grandchildren cannot change it. The location is also very clear, and the Li clan has never changed its worship for thousands of years.

Like ancient times in previous lives, worshiping ancestors is an irreplaceable ceremony in the family inheritance of the Qingkong World. Especially for the cultivation family, one small sacrifice per year and one large sacrifice per ten years, but one must be chosen in a place with beautiful mountains and rivers and vast ideas. If this is not the case, it cannot be solemn.

This year was not the year of the Li family's grand ceremony. It was possible to hold a ceremony in the ancestral hall of the old house in the city, but it was placed on the rooftop of the Longtou Mountain where the grand ceremony was unconventional. The meaning was not worthy of being told by outsiders. Of course, when the Li family worshiped their ancestors, when and where they were sacrificed, were all private affairs of the Li family, and no one paid attention to these idle things.

Longtou Mountain is located more than 20 miles west of Xuanyuan City. The mountain is hundreds of feet high and steep and upright. Among the many surrounding mountains, there is a riding appearance. Its rooftop is even more majestic. Its mountain is overlooking all the mountains, with a timeless inspiration and eight aspects. It is a rare Feng Shui treasure land. Including the Li family, many Xuanyuan City clans have built large houses here to facilitate the use of sacrifices to temples.

This mountain is not the private property of a large clan. In the past few thousand years, there have been top families in the city who rely on their outstanding talents and have great strength to build an ancestral pavilion in Fangtiantai. All of them were taken over by the Xuanyuan Sword Sect. A sword immortal once said clearly, "The Xuanyuan Sword Sect has only one ancestor within a radius of thousands of miles - Emperor Xuanyuan, and other people like chickens, dogs and thieves, and weak ants. How dare you occupy this place of Zhongling Shenxiu and Xuanyuan? It is no small matter to be able to worship you here. If you dare to have a strange intention, this is the end..." From then on, no one dares to doubt it.

On this day, Li Ji visited Longtou Mountain on site and stepped onto the rooftop. There were also tourists watching the scenery and chanting poems. He had no interest in all kinds of scenery, but he was very interested in sacrificing the rooftop itself.

The square Tiantai is an ancient system, and it is no longer verified. It is twenty feet wide and thirty feet long, stretching in a trapezoidal shape. There are high altars in front of the platform, and the ground is paved with local bluestone. However, because the age is too long, the bluestone covers less than 70%, and black and red soil may be exposed. It is not that the cultivation families have no money to repair it, but the Xuanyuan Sword Sect is too powerful. The various clans are also afraid of misunderstandings of the sword sect, so they have to go there by wind and rain. Fortunately, the sacrifice to the sky is mainly to see the scenery and gain momentum, and it does not matter whether the altar is luxurious or not.

There is a huge bronze cauldron on the altar, which is a long time ago and weighs tens of thousands of pounds. It is filled with incense ash and sand and gravel mixture. This is a popular place for ancestor worship. Every ten days and half a month, clans of all sizes always come to hold ancestor worship ceremony. It is a public place, but no one comes to visit.

After observing for a long time, Li Ji went to Longtou Mountain to understand the terrain and terrain, and had already made a decision in his mind.

—————

Liujinfang, this is the largest cultivation market in Xuanyuan City, with all kinds of cultivation supplies. Li Ji chose a shop selling equipment and materials and walked in.

"What do you need to pay for customers? Our store has complete products and fair prices, so you can be satisfied..." The guy came up with me diligently. This is also a Xuanzhao period monk. Generally, there is no need for mortals in the cultivation shop, because mortals know almost nothing about the spiritual objects of the Tao and cannot deal with customers normally.

"Silver-white iron, yellow wind stone, can it be found in stock?" Li Ji asked.

Silver and white iron and yellow wind stone are the most basic and ordinary materials for making tools. They are not worth much, and the guy is less interested after hearing this. "A ten kilograms of silver and white iron are one low-grade spirit stone, and a fifty kilograms of yellow wind stone is one low-grade spirit stone. Don't blame the guests if you don't have any discounts."

Li Ji didn't care about his attitude, and for a moment he estimated in his heart, saying, "Two thousand kilograms of silver and white iron, five thousand kilograms of yellow wind stone, if there is wood and carbon, another 10,000 kilograms."

The guy had a smile on his face. The customer probably started a small refining workshop. Although the goods he bought were not in the grade, the luck was that the quantity was large. "There were 320 low-grade spirit stones in total. You want more goods and you need to go to the backyard warehouse to collect them. I wonder how the customer took them away?"

"Using a bag." Li Ji threw him three medium-grade spirit stones and twenty low-grade spirit stones, and then went to the backyard.

On this day, Li Ji bought goods in the market. He bought bargains, and even in terms of quantity, it was not worth mentioning compared to the large workshops. Xuanyuan City is full of all kinds of large and small craft workshops. Which one of the purchase volume is not larger than that of him? No one came to pay attention to him.

After two hours, I spent dozens of medium-grade spirit stones, and bought a total of 2,000 kilograms of silver and white iron, 5,000 kilograms of yellow wind stone, 10,000 kilograms of wood carbon, a one-square bag, five-square bag, and a cheapest brass alchemy tripod. Among them, the one-square bag is the largest that Li Ji can find in the market. Because the bag is vulgar and cannot be used for a long time, it only lasts for less than half a year, no one will bother making this thing. The pavilion is the most common brass cauldron, with only the simplest temperature control array engraved, but fortunately it is large enough to heat objects in large quantities.

Li Ji began to make things that do not belong to this world in the reincarnation hall. Soil-nitrate, a white bay-like mold precipitated in the soil walls of rural pigpens and toilets, named potassium nitrate, and the purity can reach 75%. Dissolve these molds in water, add wood ash, and precipitate precipitates, and obtain a potassium nitrate solution with a purity of more than 95%. Heat and evaporate the solution until it is saturated, add ground yellow-wind stone powder and wood carbon ash powder in a certain proportion, stir evenly, turn off the heat and cool it, pour out and dry, and when it is half-dry and half-wet, put it on the stone mill to grind until the color turns from black to gray, pour out and dry thoroughly.

There are no pigpens and toilets here, but the two huge array bases of the Wheel Reincarnation Hall are equivalent to tens of millions of pigpens and toilets. The white flocs on the stone wall are about one foot thick. This is a considerable amount of engineering. Li Ji used the excuse of removing real dirt and hired a large number of hard work from the city. In less than 10 days, the finished product was filled with several bags.

Huang Fengshi was called Yihuang in Li Ji's original world.

People in this world will not know what Li Ji did, but if it were someone in his original world, even a child, they would know the name of this thing - Black Gunpowder.
