A few people discussed the next countermeasures, and Yang Xingmi smiled at this time: "Wu'er finally came back, and now I must be in a hurry to see your little lover, right?" Okay, let's go back and have a look, your little lover arrived at your sister early in the morning, and she must be impatient to wait now! ”

Yang Wu was stunned for a moment, then reacted, and couldn't help blushing, Yan Keqiu and Gao Mian on the side also said with a smile: "Congratulations to the son, I don't know when I will be able to eat the wine of the prince?" ”

Yang Wu fled. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

At this time, at Yang Jing's residence, Zhou Mengjie was already restless.

Her appearance hasn't changed much, after all, only four months have passed, but her longing for Yang Wu is getting stronger and stronger. During the time that Yang Wu was away, she would sincerely pray for God's blessing almost every day, hoping that he would come back safely.

However, at the beginning, Yang Wu often wrote to her, and asked the messenger to send it back for Yang Jing to pass it on to her; But after a period of time, fewer and fewer letters were written, which made Zhou Mengjie resentful in her heart.

Fortunately, the news of the army's continuous victories finally reassured her a lot, and it was only last month that her father told her that the southern expedition was coming to an end, and the news that Yang Wu was about to return to Guangling finally relieved her. And after learning that Yang Wu was going back to her house today, she let go of her reserve and came to Yang Jing early in the morning, wanting to see him as soon as possible.

"Why haven't you come back yet? Didn't you say you would have returned home a long time ago? Zhou Mengjie muttered to herself, Yang Jing on the side may have seen her thoughts, and said with a smile: "Look at you, you were in a hurry when my brother went on the expedition, and then you were in a hurry when you didn't receive the letter for a while, and now that he has returned home, you are still in a hurry, can't you calm down?" ”

Zhou Mengjie's face turned red, her father often went on expeditions, and she used to be worried, but then she got used to it and was not in a hurry; I didn't expect to be anxious about another man now.

Fortunately, just as Zhou Mengjie walked out of Yang Jing's boudoir for the third time and looked out, Yang Wu finally came.

He seemed to have grown much taller, his face thinner, but his eyes sharper, and he looked more majestic in his stride. Obviously, these few months in the army, especially the experience of leading a large army alone, have made him more mature.

"Childe, you're back!" Zhou Mengjie was overjoyed, she seemed to have a thousand words in her heart, but in the end, there were only these few words.

"Well, Mengjie, I'm back!" Yang Wu replied, his tone was also calm.

He took a deep breath, stepped forward, looked at the more beautiful red face, and couldn't help but hold her in his arms.

"Ah......" Zhou Mengjie was startled, and hurriedly struggled to get rid of it, she had never been hugged by a man like this, and Yang Wu had never done such intimate actions to her before.

"Don't move! Let me hug you! Yang Wu hugged her hard and whispered in her ear.

Zhou Mengjie only felt that her heart was beating faster and faster, and her heart was full of sweetness, but she subconsciously held back her shyness and let the man in front of her hug her.

"Let him go! Anyway, my father knew about our relationship, and seemed to approve of us being together. She comforted herself.

Some time ago, her mother Liu had already formally talked to her, so Zhou Mengjie also knew that her marriage to Yang Wu was almost decided.

The two stayed warm for a long time before they separated, and after returning to their yard, they had to comfort He Yiyi again, and she had lost a lot of weight during this time.

……

Three days later, in a farm outside the city of Guangling.

It's a remote place that is rarely visited. This is the gunpowder manufacturing base set up by Yang Wu.

When Yang Wu returned to Guangling from Shengzhou, he accidentally saved Ning Zhong, an expert in the manufacture of black powder, so he deliberately placed him in a small courtyard in the secluded place of the Jiedu Envoy's Mansion.

However, although it is secluded, after all, it is in the Jiedu Embassy's Mansion, and Ningzhong often makes an explosion sound when he does black powder experiments, and the guards of the Jiedu Embassy have been alarmed several times, if it weren't for Yang Wu's special cover-up, I am afraid that the secret of black powder would have been exposed long ago.

However, it is good to say that it is good to do gunpowder experiments in the Jiedu Embassy's mansion, but it is not safe to produce it on a large scale, and Yang Wu does not want to be recorded in the history books of later generations that the Wu Wang family who had been crisscrossing the Jianghuai for 20 years was hung up because of the black powder explosion. If that's the case, Yang Wu is afraid that it will become the biggest joke in history.

Now, after several months of experiments, the composition ratio of granular black powder made by Ningzhong is very reasonable, and it is very close to the optimal ratio studied in later generations, but considering the purity of the three components of this era, it can be considered that this is already the best ratio.

In order to keep it secret, Yang Wu did not use black powder in the process of attacking Suzhou and Huzhou, but Yang Wu naturally would not be polite when he quelled the rebellion of Tian Yan and others.

The black powder weapon was originally used, and the war against Suzhou and Huzhou had nothing to do with life and death for Huainan, but the rebellion of Tian Yan and others was a civil strife of life and death, and because of Yang Wu, the civil strife in this life may be more violent than in history, so there is no need to hide black powder anymore.

"What is the daily production of black powder today? How much is already in reserve? ”

Charcoal and sulfur, the three main components of black powder, are readily available, but natural saltpeter is almost non-existent. Historically, before the development of the synthetic ammonia industry, saltpeter has always been an important resource for warfare.

The British had sent a large number of people to explore and excavate near houses, barns and even churches in order to obtain saltpeter, and later relied on large imports of saltpeter from India to alleviate the shortage of saltpeter, which helped to establish its hegemony in the 18th century.

Later, Chile also had wars with Bolivia and Peru for saltpeter and guano production areas, and finally Chile won, while Bolivia ceded land because of the defeat, and finally lost access to the sea and became a landlocked country.

Fortunately, Yang Wu's demand for black powder is not so great now, after all, he does not plan to use muskets and artillery and other weapons now, and it will not be much if it is only used for blasting, so relying on the saltpeter obtained in the corner of the dry wall and the mud of the pigsty is almost enough.

"Sulfur and charcoal are easy to say, but there is not enough saltpeter, and there is a shortage of manpower, at the beginning, only more than ten catties of black powder can be produced every day, but now the output has increased, and more than 30 catties can be made every day. As for the reserves, thousands of catties have been reserved today. Ning Zhong replied neither humbly nor arrogantly.

The young man was now appointed by Yang Wu as the Gunpowder Inspector, in charge of the manufacture of gunpowder in Huainan, and perhaps in the future, he would be further responsible for the manufacture of artillery.

Yang Wu nodded, "Very good, but the daily output needs to be increased, if the manpower is insufficient, I will provide you with manpower, and if the saltpeter is insufficient, you must find a way to collect more, in short, the reserve must be increased to more than three thousand catties within two months!" ”
