Li Jiwan went to the Xichang Teahouse to find the third uncle and took a lot of spirit stones, and then his plan was to buy a large number of utensils, and just relying on his spirit stones was completely insufficient.

A low-level cultivator in the Enlightened Light Realm, if he delusionally wanted to make some trouble for a Xiuzhen family or even a top-level sect, what would he do? He didn't know what others would do, anyway, as a traversal person, he really couldn't think of any other way besides those powerful explosive weapons in his previous life.

On the seventh day of the ninth lunar month, there are still 53 days away, and the Li clan will worship their ancestors on the square rooftop of Longtou Mountain, more than 20 miles outside Xuanyuan City. The time is very clear, this is the ancestral system, and it is impossible for filial sons and grandchildren to change it. The location is also very clear, the Li family has never changed their ancestor worship for thousands of years.

Like the ancient times of the previous life, ancestor worship is an irreplaceable ritual in the family inheritance of the Blue Sky Great World. Especially in the Xiuzhen family, a small sacrifice a year, since it is possible in the family ancestral hall, a big sacrifice in ten years, but it must be selected in a place where the mountains and rivers are beautiful and the spirit is mighty.

This year is not the year of the Li family's festival, and the ceremony can be held in the ancestral hall of the old house in the city, but it is unconventionally placed on the square roof of Longtou Mountain of the big festival, which means that it is not enough for outsiders. Of course, the Li family's ancestor worship, when and where to sacrifice, are all Li family's private affairs, and no one pays attention to these idle matters.

Longtou Mountain is located in the west of Xuanyuan City more than 20 miles, the mountain is hundreds of zhang high, steep and upright, there is a phase of riding out of the dust in the surrounding many mountains, its top rooftop is the mountain is majestic, a glance at the mountains, the spirit is eternal, the four and eight phases, it is a rare feng shui treasure land. Including the Li family, many Xuanyuan City clans have built mansions here to facilitate the use of shrines.

This mountain is not the private property of a big clan, in the past thousands of years, there are also top families in the city relying on the extraordinary strength of the clan's talents, want to build an ancestral pavilion in Fang Tiantai to dominate the luck, all by the Xuanyuan Sword Sect to raise the clan a pot, there are sword immortals have clearly said, "Xuanyuan Sword Sect within a radius of 10,000 miles, there is only one ancestor - Xuanyuan Emperor, you and other chickens and dogs and thieves, ants and weak generations, how dare to occupy this Zhongling Shenxiu place and Xuanyuan side by side? Since then, no one has dared to doubt it.

On this day, Li Ji surveyed Longtou Mountain on the spot and stepped on the rooftop. There are also visitors watching the scenery in twos and threes, chanting poems to do right, he has no interest in all kinds of scenery, but he is interested in the altar itself.

Fang Tiantai is an ancient system, and it is impossible to test the years. Twenty zhang wide, thirty zhang long, stretching along the trapezoidal shape, there is a high altar built in front of the stage, the ground is paved with local bluestone, but because the age is too old, the bluestone cover has been less than seventy percent, and sometimes the black and red soil is exposed. It's not that the Xiuzhen family has no money to repair, it's really that the Xuanyuan Sword Sect is too strong, and the various clans are also afraid of the misunderstanding of the Sword Sect, so they have to let it come here in the wind and rain, fortunately, the altar is mainly for viewing the scenery, and it doesn't matter whether the altar is luxurious or not.

There is a huge bronze moment on the altar, which is very old and weighs tens of thousands of catties. Inside is incense ash, sand and stone mixture, here is a popular place to worship ancestors, every ten days and half a month there are always large and small clans to hold ancestor worship ceremonies, both for the public place, but no one to visit the idlers.

Li Ji observed for a long time, and then went to various places in Longtou Mountain to understand the topography, and he had a plan in mind.

——————

Liujinfang, here is the largest Xiuzhenfang city in Xuanyuan City, and there are all kinds of Xiuzhen supplies. Li Ji chose a shop that sold materials for making utensils and walked in.

"What do you need when customers patronize? Our store has a complete range of goods, fair prices, to ensure your satisfaction... The man greeted him with gratitude. This is also a Xuanzhao period monk, and the cultivation shop generally does not use mortals, just because mortals know almost nothing about a Dao artifact spiritual object, and they can't deal with the guests normally.

"Silver and white iron, yellow wind stone, can you have it in stock?" asked Li Ji.

Silver and white iron, yellow wind stone are the most basic and ordinary materials for making utensils, and they are not worth much, and the guys are less interested after listening to them. "Ten catties of silver and white iron is a low-grade spirit stone, and fifty catties of Huangfeng stone is a low-grade spirit stone, no discount, and the guests are not strange. “

Li Ji didn't care about his attitude, estimated for a moment in his heart, and said: "Two thousand catties of silver and white iron, five thousand catties of yellow wind stone, if there is charcoal, another ten thousand catties." “

There was a smile on the man's face, this guest is estimated to be a small refining workshop, although the goods bought are not in the grade, but fortunately, the amount is large, "A total of 320 lower grade spirit stones, you want more goods, you need to go to the backyard warehouse to pick it up, I don't know how the guest can take it away?"

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

On this day, Li Ji swept the goods in the market, he bought all the bargains, and even in terms of quantity, compared with the big workshops, it is not worth mentioning, Xuanyuan City is full of all kinds of large and small pottery workshops, which one is not larger than him? No one pays attention to him.

After two hours, the medium-grade spirit stone spent dozens of pieces, and a total of 2,000 catties of silver and white iron, 5,000 catties of yellow wind stone, 10,000 catties of wood charcoal, a bag of one zhang square, five bags of five feet square, and one of the cheapest brass danding. One of the square bags is the largest Li Ji can find in the market, because the bag is rude, and the use cannot last long, only less than half a year, so no one will bother to make this thing. Danding is the most common brass tripod, only engraved with the simplest temperature control array, but fortunately, it is large enough to heat utensils in large quantities.

Li Ji began to make things that did not belong to this world in the Wheel Hall. Soil nitrate, a white fluffy mold precipitated from the earthen walls of rural pigsty and toilets, is called potassium nitrate, and its purity can reach 75%. These molds are dissolved in water, plant ash is added, and the precipitate is precipitated, and a potassium nitrate solution with a purity of more than 95% can be obtained. The solution is heated and evaporated to saturation, according to a certain proportion of the ground yellow wind stone powder and wood carbon ash powder, stirred evenly after the fire is turned off and cooled, poured out to dry, when it is dried to a semi-dry and semi-wet state, put it on the stone mill to grind the medicine, grind until the color turns from black to gray, pour out, and dry thoroughly.

There is no pigsty here, and there is no toilet, but the two huge bases of the wheel hall are equivalent to tens of millions of pigsty toilets, and the white flocculent on the stone wall is a foot thick, which is not a small amount of work.

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

The people of this world will not know what Li Ji has made, but if it is replaced by the people of his original world, even if it is a child, they will know the name of this thing - black powder.
