Early the next morning, Guo Song took more than a dozen personal soldiers to Heigang to guard and arrest, although there were still a lot of affairs waiting for him to deal with in the official office, but he was more concerned about the research and development of firearms at this time.

Not long after, the group rode to the garrison city, and Yang Jun came out to greet him when he heard the news.

"How is the development of the new firearm progressing?" Guo Song asked.

"Envoy Qi, this time has stopped for the time being."

Guo Song was stunned, he saw Yang Jun's gloomy expression, and asked, "What's wrong?" ”

Yang Jun nodded, "There was an explosion, killing and injuring more than twenty brothers. ”

"When?" Guo Song asked.

"Half a month ago, now the news is still blocked."

Guo Song walked into the military city, only to see that the military city was deserted, and the busy scene of the past was no longer visible.

"Tell me in detail, what happened, is it related to sesame oil?"

Yang Jun nodded, "After getting the sesame oil, we began to mix, mixed with sesame oil and gunpowder, turned into oil sludge, dried and then made into particles, terrible things happened here, we generally use a bladeless blunt knife to cut the dried gunpowder pieces into small pieces, as a result, the soldiers burned violently when they were struck, and exploded together with more than a dozen porcelain fire mines in the room, and more than 20 soldiers were killed on the spot. ”

Guo Song didn't expect such serious consequences, he only knew that adding castor oil could speed up the burning speed of gunpowder, so that the gunpowder could be completely burned out in an instant, thus generating at least twice the pressure of the porcelain fire mine, and the iron-shelled fire mine could be made, but an accident occurred, killing more than 20 soldiers, and the consequences were indeed very serious.

Yang Jun almost cried, "The responsibility lies in the lowly position, it is normal for gunpowder to burn accidents, but there should be no porcelain fire and thunder in the room, the system of the lowly position is not strict, the requirements are not strict, the lowly duty is willing to bear all the responsibility, please make the king severely punished!" ”

Only then did Guo Song understand his narration, it was not the castor oil gunpowder that was to blame, but that there were more than a dozen porcelain fire mines in the room, and the burning of the gunpowder caused the explosion of the porcelain fire mines, which caused a tragedy.

However, it is unlikely that the gunpowder will explode by a simple knock alone, and it should be an accident caused by inadvertently knocking out a spark and igniting the gunpowder, which is actually an accident caused by non-standard operation and lack of attention to safety production.

Guo Song waved his hand and said: "There will be risks in doing everything, hundreds of people die in the mine every year, and the mine will not be mined?" Firearms themselves are dangerous work, and it is normal for an accident to occur, but if you don't learn a lesson, and the same accidents occur one after another, then you have to be held responsible. ”

"The lowly duty understands, and the lowly duty immediately summons the soldiers to return to work!" Yang Jun turned around to leave.

"Wait!"

Guo Song stopped him and asked, "How much sesame oil is there now?" ”

"There are two buckets, and only three catties are used for the humble position!"

"Don't worry about the iron fire and thunder, do the combustion test first, you have to time, what kind of ratio makes the gunpowder burn the fastest, and you have to find the best formula, understand?"

Yang Jun nodded, "I also found out that in the past, the porcelain fire thunder exploded, in fact, there was still a lot of gunpowder that did not burn the embers, after adding sesame oil, the gunpowder burned three percent faster, which can make all the gunpowder burn embers, so the power is more than doubled." ”

Guo Song saw that he understood quickly, and said happily: "That's the truth, and to make gunpowder, don't use the method of tapping at any time, but use crushing, this is a lesson you must learn." ”

"Remember, the strictest system will be put in place, and there will never be another explosion."

.........

After returning from Heigang, Guo Song returned to the official office, and at the same time he asked his own soldiers to invite Shi Eun.

There were dozens of important documents that had to be approved by him on the table of the official room, Guo Song sat on the wide chair that he had not seen for a long time, he didn't like to kneel and sit, so he made a two-foot high couch, and the legs could hang down naturally, and the table also increased with the height, wide and large, and the influence of the festival was huge, and soon, all the official rooms were transformed into the same table and couch.

At this time, Zhang Qianyi walked into the room, handed a holy decree to Guo Song and said with a smile: "This is the holy decree sent ten days ago, let you take a look!" ”

"Chengdu or Chang'an?" Guo Song asked with a smile.

"Of course it's Chengdu, Chang'an is self-aware, don't want to touch a nose of ash?"

Guo Song opened the holy decree and actually named himself a lieutenant, and also canonized his wife as the princess of the county, he smiled and said: "I can't imagine that I am only thirty years old, and I am already a dignified lieutenant, how many people will not be able to sleep at night." ”

"Everyone is discussing, in the future, will you call the envoy His Royal Highness, or the Captain?"

Guo Song shook his head, "Everyone else wants to call me the king and call me lonely, but I don't like it, or call me the king, and the captain can also do it." ”

"The lowly will tell everyone, besides, there is no more in the Northern Tang Dynasty, do you know?"

Guo Song was stunned, "When did it happen?" ”

"A month ago, Li Yu issued an edict announcing his abdication, and was sent to Chang'an by the Yuan family, and Chang'an did not take them in, and sent their family to Chengdu, it is estimated that the Son of Heaven will not spare him."

Guo Song was not interested in Li Yu, he was more concerned about the Yuan family, and he asked again: "What about the Yuan family?" ”

"The Yuan family surrendered to Zhu Zhu, and Chang'an Li only named Yuan Xuanhu as the king and allowed him to build a feudal town."

"What's the big deal?" Guo Song asked again.

"Zhu Zhu occupied Luoyang, the west of Zhengzhou is his territory, Li Baozhen and Ma Sui gave up Hebei, crossed the Yellow River to Bianzhou, at present Li Baozhen garrison in Yuzhou, Ma Sui garrison in Chenzhou, the imperial court in the Central Plains only left the five states of Slip, Bian, Song, Chen, and Henan, Xiangzhou and Weizhou were occupied by Tian Yue, and the entire Hebei and Hedong fell."

Guo Song sighed slightly, "As long as people take a step back, it will be difficult to move forward, when Li Shi decided to go to Chengdu, it was already destined that it would be difficult for him to return to Chang'an, if he insisted on staying in Guanzhong or Longyou, maybe there would be a turnaround." ”

"The envoy is right, I heard that the Son of Heaven spent five million yuan to build the Cong'an Palace in Chengdu, which is extremely luxurious, and once he is comfortable in Bashu, he will gradually lose his enterprising spirit."

Guo Song sighed and smiled: "There is something I want to discuss with you, the lack of long history in the Beiting Jiedu Mansion, are you interested?" ”

Zhang Qianyi's heart became excited, and he hurriedly said: "Of course I am willing to go to the humble position, but I am afraid that the humble position will be shallow and live up to the great trust of the envoy." ”

"You don't have to be modest, I know your ability very well, to be honest, if it weren't for the lack of people in Beiting, I wouldn't want to let you go."

"It seems that Zhao Sima didn't come back this time."

"Zhao Wei, I asked him to serve as the assassin of Xizhou, his side is also in chaos, several counties are still paralyzed, you go to Beiting, and at the same time serve as the assassin of Tingzhou, while stabilizing Tingzhou, we must also focus on Xizhou, once the enemy army invades Beiting on a large scale, Tingzhou can't stop it, Xizhou is our last barrier."

"Ignorance, understood!"

"You and Xiao Du will hand over, and the day after tomorrow will set off with the people of Gaochang and take your wife to Tingzhou together."

Zhang Qianyi nodded and retreated, and at this time, the soldiers reported at the door, "Lord Shi is here!" ”

Guo Song hurriedly greeted him out, only to see Shi Donglai and his son Shi Eun walking in.

Guo Song smiled: "How can Lord Shi be in Zhangye? ”

Shi Donglai said with a smile: "Envoy Jun to invade the Western Regions, this is a big deal, of course I have to come over, many Sogdian merchants in Chang'an have returned, and everyone is very concerned about the situation in Beiting." ”

"The war is over, Shatuo is dead, and you will have one less exploit in the future."

Shi Donglai nodded, "What the envoy said is very right, Shatuo's tax is heavy, and the tax is generally levied at one percent, without Shatuo's exploitation, we are much easier." ”

Guo Song invited their father and son into the official room, and the two sides sat down separately, while Shi Eun stood behind his father, and a tea boy came in and served them tea.

Guo Song smiled and asked, "How is the situation in Chang'an?" ”

"Chang'an has basically stabilized, but it is not very sluggish, business is difficult to do, the general people are difficult to find, and the errands of two yuan a month are competing to break the head, that is, Guangtong warehouse has a huge amount of grain reserves, once the grain consumption of Guangtong warehouse is almost the same, the crisis of Chang'an is coming."

Guo Song nodded, took out a small bottle full of castor oil from the drawer, handed it to Shi Donglai, and said, "Is this kind of sesame oil in stock in Zhangye?" ”

Guo Song believes that the historian will not buy castor oil specifically for Shatuo, it must be bought in large quantities, and Shatuo bought a part, otherwise the cost is too great, and the historian will not do this kind of loss-making business.

Shi Donglai sniffed the bottle and said with a smile: "It turned out to be it, Zhangye has no inventory, but Chang'an has five hundred barrels of inventory, how much does the envoy want?" ”

Guo Song was overjoyed, there were actually five hundred barrels, and he said happily: "I want them all!" ”
