The ratio of gunpowder to each component is reasonable in order to burst out of amazing power, the ancestors after several tests to find that sulfur 10, charcoal 1005, saltpeter 75 is the best ratio.

In order to test the real effect of this ratio, Wang Xuan set up a gunpowder research institute in the research institute, and selected some young people who were literate and hyphenated to participate in the research experiment, and the location was temporarily set up in the temporary office of the former government affairs yuan next door to the lord's mansion.

The first step is to test how to obtain high-purity charcoal, sulfur and saltpeter.

Charcoal can be fired in the experimental kiln of a brick or porcelain factory, and the wood can be heated to a certain temperature without oxygen.

The easiest way to obtain pure sulfur is to collect the steam by distilling it at high temperatures, just like making pure water, and then cool it down.

The step is to heat the sulfur in an iron pot until it melts, and constantly stir the mixed liquid to volatilize the impurities in it. It is then heated until the liquid boils, at which point steam is introduced into the ceramic pipes and flows into the vessel to cool and crystallize, which is the purer form of sulfur.

The purification of saltpeter is relatively simple, the saltpeter mixture is dissolved in hot water, the insoluble substances are filtered out after saturation, and then the solution is cooled to room temperature, and the precipitated substances are pure saltpeter.

The second step is to crush the proportion, grind these three substances into powdery particles of uniform size, then weigh and mix and stir evenly, pour them into the ceramic shell, and install the lead to the finished grenade.

In order to increase the throwing distance, Wang Xuan also made a small catapult from bamboo, which could throw five grenades at a time to a distance of 40 zhang, which was higher than the effective range of the bow and arrow, and belonged to the sharp weapon for defending the city.

It was the end of June after all this, and the officials of the Ministry of Rites sent by Wang Du to inform the condolences had been dealt with by Zhao Sheng, so Wang Xuan had to put on a smoky makeup and lay on the bed for two days, and he almost had prickly heat on his body.

The old king will be buried in the royal tomb on July 15, 55 years of the Xia Yuan calendar, and Zhao Sheng will attend the funeral on behalf of Ji Xiangling, which is also a unanimous resolution.

Once the funeral is over, no one can predict how the situation will turn, but for Jixiang, the biggest enemy is Red Flame.

Chiyan is the most likely and most likely to invade Jixiang again, the mountain road between the two places has been made passable by a large army through continuous repairs, whether Chiyan invades Jixiang by himself or invades Jixiang with other territories, Dongshan Pass is a must-pass place, Wang Xuan had to go here again to inspect and show his determination.

On the last day of June, there was a light rain in the sky, the wind was a little strong, and the curtain of the carriage was whirring.

The Dongshan Pass was completed at the end of March, and now it has gained some popularity, hawker stalls can be seen everywhere, and the not very spacious streets pass by a patrol of sergeants from time to time, and people take it calmly, as if they have become commonplace in this military city, and do not show any discomfort, and people who know each other will take the initiative to say hello.

Wang Xuan's arrival did not break the daily tranquility of the pass, the birds still foraged for food under the eaves under the wind and rain, the war horses lined up neatly on the edge of the stone trough to enjoy the fat young leaves, from time to time there were a few sneezes roaring, and the transport vehicles stopped at the city gate in an orderly manner to wait for inspection, not in a hurry or impatient.

If possible, Wang Xuan hoped that it would always be so harmonious and serene, that the soldiers would be loyal to their duties, that the people would live and work in peace and contentment, and that even the early birds would quietly pick up the spilled grains and the lucky insects. Two years of recuperation is not enough for the bullied and traumatized mascots, who lost their loved ones, their dignity and almost lost hope of living two years ago. Now, it may be that even this hard-won peace and tranquility will be lost, how unjust!

The raindrops gradually became heavier, hitting Wang Xuan's face crackling, and his cheeks were already numb, and he couldn't feel pain. The city wall facing north was three feet higher than that facing south, Wang Xuan stood at the head of the city facing north and looked out to the far north, and on the other side of the heavy rain curtain seemed to be hiding a greedy black wolf who was polishing its fangs and claws, and began to prepare for the hunt.

"Lord, it's raining heavily, so let's go inside. Yang Tao glanced at Zhang Peiyu beside him, and finally persuaded him.

"Let's go to the war room. Wang Xuan retracted his gaze and turned to enter the war room of the city tower.

Dongshan Pass is under military management and does not have an administrative body, so the participants are all soldiers.

"The old king is gone, and Great Xia is going to be in chaos. Wang Xuandao.

"Show me the Lord. After that, everyone stood up and gave a standard military salute to Wang Xuan, with firm and calm eyes.

"I don't have anything to instruct, war is about time, place, people, and now we don't lack anything. You don't have to worry about logistics, even if you carry it on your shoulder, it won't be short of you, and new weapons and armor are also being made, and they will be sent to the munitions depot at the pass by the end of next month. ”

Speaking of this, Wang Xuan stood up, calmly looked at every resolute face present, who knew or did not know, and said in a somewhat heavy tone: "The war is coming, I hope that even if you are all killed in battle, you will give me a day to hold on, and after one day, the auspicious development results will be preserved, and I will avenge your revenge." ”

The scene was as silent as death, and everyone seemed to have foreseen that there would be a day of indifference, Zhang Peiyu took the lead in making a kneeling supreme military salute, and then everyone knelt down one after another.

This is not only a military salute, but also a military order of this era, soldiers do not repeat their words, they must express their determination with actions, and they will not rest until death.

Wang Xuan silently watched the crowd, as if he wanted to imprint their faces in his mind.

Although there is a generational weapon such as gunpowder, no one can guarantee what the final result will be, and the war will kill people, maybe it is him, or maybe it is him.

Dongshan Pass is the last barrier of auspiciousness, as Wang Xuan said, even if all the passes are killed, there is no room for loss, otherwise less than 200,000 mascots can not stop several times the enemy, not to mention some scavenging vultures around them, once auspicious shows defeat, they will not hesitate to pounce and tear off a few pieces of flesh from the bloody wounds, Wang Xuan firmly believes in this. Auspiciousness can't afford to lose, even if it's a small pass.

"Get up, this is the worst plan, in short, people are at the pass, and people are at the pass. Except for ourselves, no one cares about our life or death, we can only put it to death and live later, even if it is a hundred and one hopes, we have to fight with our lives. In addition, you have to free up enough room within a month to set up a field hospital, this is the drawing, and the logistics department of the relevant medicinal materials and equipment is already processing. From now on, personnel coming from the north should be strictly checked, and the city gate should be increased to three shifts on duty, and a secret guard should be added at the junction with Chiyan in case of accidents. After saying this, Wang Xuan returned to Jixiang City.

In the conference room on the third floor of the Government Council, the military's high-level officials had been waiting for a long time, and Wang Xuan directly gave an order.

"The Xishan garrison sent 300 people to settle in the Dongshan Pass, and Yu Bo personally led the team to go there, under the command of Zhang Peiyu. ”

"The office is commanded. A swarthy man stood up and saluted.

"The 500 security teams in the north of the city were dispatched to Dongshan Pass to assist in defending the city, and another 200 were dispatched to guard the embankment in the east of the river. ”

"The office is commanded. A tall, lanky man stood up and saluted.

"The construction of the lake embankment will not be completed in two months, and this period is the most dangerous, so General Wang Yu will sit on the lake embankment tomorrow, and the troops defending the city will be assigned a hundred for you to command. ”

"The office is commanded. Wang Yu is not young, and his answer is full of energy.

In addition, another 100 internal guards were dispatched, of which 60 were Wang Yu's personal guards, and the remaining 40 were used as gendarmes to assist in defending the city at Dongshan Pass. "This is also a last resort decision for the sake of insurance, if Wang Xuanzhen wants to sit in Dongshan in person, he will also have the feat of 'talking and laughing and disappearing'.

"Counting the security patrol in the north of the city, Jixiang currently has only 2,000 troops, and everyone must be able to use one as ten in wartime, and the new training method has been promoted for more than half a year. That's why I decided to conduct a large-scale all-army exercise in mid-July, with mules and horses coming out for a walk. ”

This is the real purpose of this meeting, Wang Xuan hopes to find out through the exercise and make up for the shortcomings in time, although it is a temporary rush, but there is still some time available.

Subsequently, all the generals were assigned the task of military training, and the personnel of the staff office had only half a month to design the exercise plan according to Wang Xuan's requirements, which was quite urgent.

The next day, Wang Xuan invited Aunt Liu's brother, that is, Dr. Liu, who treated Wang Xuan, to inform him of the setting, function, and operation of the field hospital, as well as how to make sterile gauze and the use of disinfectant alcohol. Wang Xuan had to deal with the past on the grounds that there were many things and he had no time to take care of them.

Subsequently, the two discussed the formation of a wartime emergency medical team, from personnel to training, from equipment to finished medicines. Dr. Liu treats medicine very strictly, and some of the first-aid tools proposed by Wang Xuan rushed out a batch of samples at his strong request, in his words, seeing is believing, otherwise the psychology is always unreliable.

Wang Xuan arranged for people to make simple stretchers out of bamboo, curved bamboo boards and plasters to fix fractures, medical alcohol to clean and disinfect wounds, needles and sheep intestines to suture wounds, scalpels, tweezers, scissors, forceps for surgery, etc., and also specifically explained that gauze cooked at high temperature would reduce wound infection.

Of course, this cannot be verified for the time being, and Wang Xuan does not plan to disclose the statement of bacteria, which will take time.

As for the management of the field hospital, Wang Xuan also put forward his own suggestions: first, the environment requires ventilation, cleanliness and tidiness, direct sunlight can be reached, and lime disinfection is also indispensable; second, the employment of female nursing staff requires courage and carefulness; third, consider joining the psychotherapy project to enhance the sergeant's desire to survive; fourth, the reasonable combination of diet and nutrition is conducive to the rapid recovery of the body......

For several days in a row, the two of them discussed all aspects of these details, and some famous doctors in the territory were also gathered together to improve the plan for effective relief in wartime. Regardless of the outcome of the discussion, these doctors have benefited a lot from these discussions and exchanges.
