After the firewood was laid, Wang Huan smashed the basket of pyrite brought back from the outside with a hammer, carefully spread it on the firewood, and then spread another layer of dry firewood on top of it, and on top of the dry firewood, there was another layer of ore, and so on, until all the ore in that basket was laid in, and then it was counted.

The stacked firewood and ore were already more than two people high, Wang Huan lit the firewood pile below, let the entire ore firewood pile burn, and finally pasted soil and grass on the outer layer, sealing the burning firewood, leaving only a few ventilation holes at the top, clapping his hands, and ordering: "No one is allowed to approach, show me, don't let the fire go out." ”

Leaving a few people to watch, Wang Huan came to the other side of the square again, a few guards had already slaughtered a fat pig, and with a smile, they used a knife to separate the fat and bones in the pork.

Wang Huan disdained the pork, took the dozens of catties of fat and oily fat, and put it into a three-foot square stone pool, which was full of lime, and as soon as the fat was put in, the "squeak" began to smoke.

Wang Huan covered the pool with a large wooden cover, and also told the guards not to let others approach, but the content of the advice changed: "Never steal the fat inside!" Eat the one who will die! ”

The guards salivated and agreed, but they couldn't understand in their hearts, why did the adults marinate such good pork in lime, and who would dare to eat it?

Wang Huan was relieved after finishing these things, looking at two places, one ore burning emitting yellow smoke, one fat decomposition emitting white smoke, the air was yellow and white, and the whole square was full of smoke, like a workshop.

"Next, it's time to wait, and in twelve days, come back to pick it up." Wang Huan took the sweat towel handed by Xu Tiezhu and wiped the sweat on his forehead.

Xu Tiezhu looked at everything Wang Huan did in a daze, he didn't know why, he didn't know how to open his mouth if he wanted to ask, in his opinion, what Wang Huan did was a bit like a craftsman refining something, and it was a bit like a witchcraft practice, but what it was, he didn't dare to ask.

"I hope that before Zeng Ying's soldiers and horses come, it can be built, otherwise the official road will be blocked, and it will be very troublesome for us to enter Chongqing by ourselves in the future." Wang Huan frowned and looked at the yellow and white smoke, and stood for a while, the pungent smell in the smoke made him run away.

In the following days, Wang Huan supervised the construction site of Wanshou City every day, the long city wall, built farther and farther, surrounded by a radius of five miles of Wanshou City, gradually enclosed into a square circle, high wall, loess rammed, thick and tight, giving people an indestructible feeling, the wall head buttress female wall, the fortifications are all-encompassing, the city wall every dozens of zhang, there is a section of protruding wall, stretching out more than ten zhang, looking down from the air, like a huge animal has grown countless legs, this is called a horse face, the front is narrow, The purpose is to be able to flank the besieging enemy from above, which is very sharp.

And every afternoon, Wang Huan went to the school field that had been crushed and leveled to train the 100-person team, during his absence, the 100-person team was in charge of Ma Xintian's deputy Qianhu Ma Long, Ma Long is a veteran who was printed out of a mold with Ma Xintian, his personality is moody, old and steady, but he is older, about 30 years old, but he is more rigid than Ma Xintian, meticulously in accordance with Wang Huan's training methods, beating the recruits of the 100-person team.

Standing in a military posture, walking in unison, standing upright, taking a break, holding a gun, raising a gun, these boring actions almost made the young men in the hundred-person team cry, if it weren't for Wang Huan's harsh military discipline, the whole family of the deserter who dared to be a deserter was driven out of Wanshou Valley, I am afraid that more than half of the people who stayed here would be less.

Wang Huan joined in, also stood in a military posture and practiced physique every day, around the edge of Wanshou Valley every day, taking the lead in running a five-kilometer cross-country, the blisters on his feet were blistered and broken, broken and long, and finally, they became calluses one by one, and the knife could not be cut off.

The novelty push-ups also made the recruits squeak their teeth, two hundred for a group, one group must be done before breakfast, lunch and dinner, and the meal will be halved if it can't be finished, in order to have a full meal, the recruits gritted their teeth and stood up, especially when they saw that the top official Wang Huan was also insisting on lying on the ground in pain, no one dared to complain.

Drill and practice with the soldiers, who dares to disobey such a leader.

However, after a month, the spirit of the hundred-man team has undergone a huge change, the original standing crooked team has become a straight line, the loose and sagging people have become high-headed soldiers, the sloppy eyes have also become sharp eyes, the skinny body gradually straightened up, the solid and dark muscles supported the linen short clothes, and more than 100 people have been reborn from ordinary homeless people to soldiers who are beginning to show their edge.

Ma Long's mentality has also changed from the idea of following Wang Huan to the admiration in his heart, he weighed himself, if he changed himself to train these soldiers, a month's time, no matter what, can not do such an obvious effect now, compared with the two, the misunderstanding that Wang Huan does not know soldiers and does not understand the method of training immediately changed, and he learned from Wang Huan wholeheartedly.

Wang Huan himself has also changed, full of food every day, balanced nutrition, the thin little monk in Yangzhou City, the size has jumped a lot, the toned muscles are evenly spread all over the body, showing full masculinity, the hair has grown long enough to wear a scarf and a bun, with a handsome face, put on a armor and a heroic posture, wear a Confucian shirt with a graceful demeanor, hold a long sword and be murderous, holding a folding fan in his hand and elegant style, Wanshou City is proud of him.

On the morning of the twelfth day, the weather was sunny, Wang Huan wore a black cloth to cover his face, protected his mouth and nose, and stood on the square in the official office.

Among them, there is Ma Xintian, because of the news sent back by Chen Xiang, there has been no movement in the direction of Chongqing, Wang Huan felt that Ma Xintian was wasted in the Black Valley and was boring, so he simply used Ma Long to replace him back.

Ma Wannian and the others were all strange and inexplicable, looking at the two smoking places, and at the huge earthen furnace in the middle of the square, exchanging glances with each other, at a loss.

Wang Huan confidently asked someone to use an iron drill to poke open the burning pyre, the outer layer of soil and grass collapsed, and a huge yellow smoke rose, pungent and unpleasant, and when the yellow smoke dissipated, you can see that the firewood ore inside has been burned, only a pile of ashes is still billowing green smoke.

Wang Huan ordered people to carefully sweep the ashes clean, put them into a large copper basin, the basin was full of water, stirred with a long stick, into a basin of black paste, and then filtered with a fine sieve, poured out some transparent viscous liquid from the basin, put these liquids in another basin, covered with a lid, and set up a fire under the basin to grill.

After burning for more than an hour, Wang Huan lifted the lid and saw that the liquid in the basin had turned into tiny crystals, yellow and white, like salt grains.

Wang Huan brought a huge crockpot, poured these crystals that had been obtained for a long time into the crockpot, and put the crockpot on the fire and roasted it.

Ma Wannian and the others stood aside, covering their mouths and noses with black cloths, watching Wang Huan busy like a fool, unable to help at all, staring at the sidelines.

As the flames churned, a large stream of steam rose in the crockpot, Wang Huan hurriedly closed the crockpot with a wooden lid, and waited quietly with a nervous expression, and only after about two hours did he lift the lid, and there were no crystals in the crockpot, and it turned into half a jar of liquid.

Wang Huan put on a pair of thick gloves, carefully tilted the clay pot, and slowly poured the "sizzling" liquid into a clay pot filled with saltpeter, and suddenly an unpleasant smell arose, several times worse than the smell just now.

The clay pot is like a river and a sea, the liquid is extremely corrosive, and the hard fire ore is slowly corroded away, crackling and exploding, and gradually turning into a pool of transparent water-like things.

Wang Huan covered the clay pot with a clay lid and turned to the edge of the lime pool.

Ma Wannian and the others followed Wang Huan step by step, only to see Wang Huan open the lid of the lime pool, and everyone stretched out their heads to see that the large piece of fat had long been gone, and had turned into a pool of clear white pool water.

Everyone's flesh hurts, what a good meat, it's been ruined like this!

Wang Huan didn't care, and ordered someone to take a long spoon, reach into the pool, scoop out all the water in the pool, put it into a large wooden barrel, and scooped a full bucket.

Wang Huan took a bowl, scooped a bowl from the bucket, walked to the edge of the clay pot that had stopped exploding, and lifted the lid with a wooden stick far away.

A sticky and rotten sour gas rose into the air, rushing straight to the sky, Wang Huan waited for the sour gas to run out, and then slowly approached, using a pottery spoon, gently scooping up a spoonful of acid in the clay pot.

He drove everyone around him far away, squatted on the ground alone, concentrated, and slowly added the acid from the spoon to the bowl, and the acid slowly flowed into the clear liquid in the bowl, neutralized together, and turned into a slightly yellowish oily liquid.

Wang Huan took a long breath, held the earthen bowl in both hands, and said softly to the onlookers like a treasure: "Everyone, this is our killer feature, nitroglycerin." ”
