"Boom", another grenade exploded in the time and space of the Tang Dynasty, Li Er and Zhong Wenwu looked at the livestock that fell to the ground on the school field, and their faces twitched. Pen, fun, pavilion www. biquge。 info

"Lin Feng, how is this grenade made?" Li Er's vision is high, what he wants is not one or two, this manufacturing process must be in his hands, otherwise he will be controlled by others.

Lin Feng repeated what he had said to Cheng Yanjin, and Li Er asked the people from the Ministry of Industry to write it down and continued to ask about the explosion. Lin Feng said: "One nitrate, two sulfur and three charcoal. ”

Many people may misunderstand, including many other novels, that this ratio is one to two to three, but in fact, the real ratio is one pound of saltpeter, two taels of sulfur, three taels of charcoal. In ancient times, a pound was sixteen taels, so the modern ratio is sixteen to two to three.

Li Er also misunderstood, so Lin Feng took a lot of trouble to explain clearly, fortunately, these materials have long been familiar, charcoal needless to say, it was used in metallurgy during the Shang and Zhou dynasties, and even earlier charcoal was used as fuel.

Saltpeter in the Han Dynasty's Shennong Materia Medica has been listed as the sixth among the top medicines, and sulfur is listed as the third among the Chinese medicines, the main reason is because these things are used by the Fang Shi to refine the elixir of life. Even earlier, around the sixth century B.C., in the late Spring and Autumn Period, there was a person named Ji Ran who said: "Shiliu Huang out of Hanzhong" and "Stone out of Longdao". Stone flow yellow is sulfur; Eliminated stone is saltpeter.

Li Er immediately asked the Ministry of Industry to arrange for the ordnance supervisor to try out the production according to the method given by Lin Feng, but Lin Feng stopped him and said, "Your Majesty, this thing is too dangerous, I will arrange someone to help." ”

Li Er is very happy, Lin Feng is the best to take the initiative, save yourself your own saliva, this kind of black technology is still in your own hands, it's good to blow up mosquitoes and play with nothing.

Yang Biao was sent by Lin Feng to assist the Ordnance Supervisor in manufacturing black powder and grenades.

"Lin Feng, there has been news recently, Shandong has seen little rain since the beginning of spring, and there has been a trend of drought, and please also use the art of praying for rain to relieve the suffering of the people." Li Er has also been worried these days, before the summer, a large area of Shandong has been dry, the river flow has decreased, and the rainfall is insufficient.

Spring rain is as expensive as oil is not an empty word, especially in North China, overwintering crops back to the milk maturity stage, spring crops are sown into seedlings, need sufficient water, spring does not rain on the impact of production is not generally large, it is likely to be a large-scale harvest.

"It's easy to say, I'll open the altar and cast spells when I go back, and it will rain lightly." Lin Feng knew that there would be no heavy rain in spring, and the seeds could be washed away, so he could only use a small amount of time many times and slowly fall.

Li Er rubbed his hands, without the appearance of an emperor: "I have thanked Tianzun for the people." "This is the first task given to Lin Feng, the protector of the country, and the title is very official, and it also means to test Lin Feng's technique of praying for rain again.

Lin Feng took over the task, and when he went back, he opened a super-large range of spatial passages covering North China, and the other end of the spatial passages was divided into many ones, each of which was in an area with light rain. There is no way, there is no place for such widespread rainfall, so this is the only way.

It rained lightly for six or seven days, and Li Er personally rushed to Lin Feng: "Lin Feng, that's enough, if it rains again, the ground will be flooded." ”

Since Li Er told Lin Feng to pray for rain, he sent countless sentinels to various parts of Shandong, and the weather situation was reported daily. In the first few days, the whole Shandong was a sea of laughter, and after looking forward to the rain for so long, it finally rained.

But after six days in a row, I was a little panicked, and it didn't work if I continued to do so. The sentinels sent the information, and Li Er came directly to Lin Feng's house.

"Ah, that's enough, no one told me." Lin Feng shook the pot, and it rained anyway. Put away the space passage: "Your Majesty, the rain has stopped." ”

"It's good to stop, it's good to stop." Li Er now believes in Lin Feng completely, and this ability to call for wind and rain can be found in the Tang Dynasty, and he can't find one.

Lin Feng invited Li Er to sit down and drink tea, and chatted by the way: "That grenade is almost made, right?" ”

"The ordnance supervisor has reported that the shell has been cast, the gunpowder has been configured, and it is being assembled, and it will be able to be tested today."

"When it's ready, it's time to send reinforcements to support the counterinsurgency, right?" Lin Feng wants to give the four King Kongs the opportunity to fight for meritorious service, anyway, staying in Chang'an all day long is also idle, and he squats in his own house to eat and drink, smoke and play mahjong.

Li Er nodded, and didn't mind Lin Feng's interference in the military: "50,000 elites have been mobilized, with Li Jing as the head of the march, Qin Qiong as the deputy, and they set off the day before yesterday." After the grenades are made, they will be divided into two batches, one group will be transported by fast horses, and one will be transported to Taiyuan Mansion with logistics. ”

"In this way, then Qin Huaiyu, Cheng Chumo, Yu Chi Baolin and Fang Yiai have plans to go into battle, what does Your Majesty think?"

"It's good for young people to get some exercise." Li Er also has the idea of training newcomers, so as not to be green and yellow in the future, and he has to send veterans to expedition wherever he wants to fight.

Lin Feng stood up and shouted out the door: "Brothers, come here." ”

The four King Kongs swished in the room, and they all saluted: "See Your Majesty." ”

Li Er is a little flustered, I'll rub, wait for me here!

"No courtesy. Are the four of you willing to go into battle and kill the enemy? ”

"Your ministers are willing."

"In this way, I will order the four of you to set off on the same day and go to the front line to listen to it." Li Er is not worried about the problems of the four young people, there are Li Jing, the god of war, the eldest grandson, Wuji, a high-ranking black-bellied person, and Qin Qiong, a fierce general, will not let the four young people fight a tough battle. As for the injured Wei Chigong, ignore it for the time being.

The Four Great King Kongs showed joy on their faces, they could finally go into battle to make meritorious contributions, and then their faces darkened, and they could no longer be as comfortable as Lin Feng's family during the days of going on the expedition, thinking about it, they were suddenly a little reluctant.

"Brother Lin!" The four of them shouted in unison, full of emotion.

Lin Feng was moved, and his eyes were red: "Brothers, pay attention to safety, I will miss you." ”

"Brother Lin, when we come back, come to your place to eat and drink, remember to prepare more delicious food." One sentence exposes the small tails of the four.

"Damn, you guys get out of the labor, don't come back." Lin Feng was deceived into tears, and he didn't care if Li Er was still there, so he sprayed directly.

"Don't rush people first, you have a lot of treasures in this palace, do you have any divine armor, give us a set." Cheng Chumo cheekily ate and asked for the card.

"Nope." Lin Feng shook his head, rub, the emperor is still here, you are talking about a hairy divine weapon armor here, you can't say it.

"Brother Lin, you are not righteous, my brothers are going to go into battle to quell the rebellion, and you don't even give a weapon and armor, it really hurts your feelings."

Li Er knew that he was in the way, and coughed: "I am busy with state affairs, and I still have important things to deal with, so I will go back to the palace first." ”

Lin Feng and the Four King Kongs hurriedly sent Li Ershan, Li Ershan came lightly, a carriage with dozens of guards, it can be regarded as a light and simple obedience, who made Lin Feng close to Yanxi Gate here. (To be continued.) )
