Saltpeter, charcoal, sulfur, these basic materials are not rare, and they are produced in the Dongsheng Empire, Yuan Fang put away the recipe and fell into a dilemma. Gunpowder is a very useful thing, especially in the military aspect, if used properly, it will greatly increase the military power of the Dongsheng Empire, but in the same way, the disadvantages of gunpowder are not small.

Before, Yuan Fang never thought that he would have the opportunity to advance this world into the era of hot weapons, because he didn't know the formula of gunpowder at all, but now that he has it, Yuan Fang has it, so should he make this thing public?

The beginning of the new era represents a new war, and the pattern of the world will inevitably change because of this, Yuan Fang only wanted to make a small fight to ensure that the Dongsheng Empire was not bullied, if he really made a musket cannon, at that time, how would Yang Xing choose?

Will they rest on their laurels or will they rely on a strong military force to expand aggressively?

Thinking about the matter of the Eastern Expedition Yuan and the Empire, Yuan Fang was big for a while, his mood was quite contradictory, the Eastern Expedition was an idea he proposed, and now, he felt that this was a little, no, not a little, it was very unkind, in order to live a better life, he cruelly snatched other people's land, is this right or wrong? This kind of thing is really not clear, the Yuan and Empire joined forces with other countries to deal with the Dongsheng Empire before, and now the Dongsheng Empire is turning around against them, it stands to reason that this is a very normal thing, but Yuan Fang's heart is a little unbearable, in Chang Xun's words, it is the benevolence of a woman.

Sighing and digging out these complicated questions, Yuan Fang walked out of the room and asked Sang Rou in the outer room: "When will the reinforcements arrive?" Any news? ”

Sang Rou coughed a few times and said, "Not yet, I can have news in the middle of the night, brother-in-law, what are you doing when you don't take a break?" ”

Yuan Fang scratched his head and said, "There are some things that I can't figure out, I can't sleep, go out to breathe." ”

Yuzuki put on a piece of clothing, coughed lightly and said, "Oh, I'll accompany you." Yuan Fang nodded and walked out.

At this time, Xia Yi, who had already fallen asleep, also coughed a few times, Yuan Fang felt that something was wrong, turned around and walked to Xia Yi's side, grabbed her wrist to check the pulse, and then gave Sang Rou and Jieyue the pulse again, frowned and said, "Where do you feel uncomfortable?" ”

Sang Rou shook her head and said, "I don't feel uncomfortable, but I just have a little cough, maybe it's a cold." Yuan Fang frowned, leaving Yuyue to take care of the sleeping Ye Qingru and Xia Yi, and took Sang Rou to find Xueqin.

Sure enough, Xueqin and the flight crew who flew above the clouds together before had similar symptoms to Sang Rou, but fortunately, they were not too serious, only Xueqin's ears were a little troublesome, and it would take a period of conditioning to recover.

I found the military doctor and told the situation that the military doctor didn't know anything about ozone, but it was easy to roughly figure out the condition, that night, the military doctor used the herbs brought to boil a lot of decoction to clear the lungs and moisten the lungs for Xueqin and them to take, and the next morning, everyone's cough symptoms were greatly relieved, and there was no major problem. Yuan Fang didn't rest much all night, he couldn't sleep when he was lying on the bed tossing and turning, as soon as the day dawned, Yuan Fang got up and washed and changed his clothes to go out, and he received news last night that the support troops had set off and would arrive in about a day, and Yuan Fang wanted to find out the situation of the Wanliu Empire as much as possible during this time.

Came to Ren Fei's room, Ren Fei was still asleep, Yuan Fang checked Ren Fei's injury, and was annoyed, although he had seen it last night, but once again saw the shocking scars on Ren Fei's body Yuan Fang still couldn't help but have the urge to kill, especially the deep whip marks on Ren Fei's face, even if the wound healed, it would definitely leave a scar.

Yuan Fang asked the military doctor who came to change the medicine softly: "Is the penicillin you brought enough?" ”

The military doctor shook his head slightly and said, "It's not enough, but I've already sent a letter back to someone to send it, and it will arrive in the evening, it's all purified penicillin, the dean can rest assured, they will be fine." Yuan Fang nodded, sat at the head of the bed and looked at the haggard Ren Fei in a daze.

Time passed little by little, Sang Rou beckoned at the door, and Yuan Fang went out to ask, "What's wrong?" ”

Sang Rou pointed to the stone chamber next to him and said, "Someone woke up, it's Jiang Yishui." Yuan Fang didn't talk nonsense, and went directly into the stone room.

After some checking, Jiang Yishui was very weak, and the torture during this period of time was probably deep into the bone marrow and left the root of the disease, Yuan Fang was deeply sympathetic but helpless, he didn't know much about the treatment of his heart, and he could only hope that Jiang Yishui's strong will would not be affected too much.

After some inquiry, Jiang Yishui told Yuan Fang what he knew without concealment, and to Yuan Fang's disappointment, Jiang Yishui was not very clear about the affairs of the Wanliu Empire, only knew that Ren Fei hurriedly found him at that time, and then they took a boat to the sea to rush to the safety station, there was a small island on the island, there was a small boat specially prepared for them on the island, and then they got on the airship, and finally, when they were supplying on this island and preparing to contact others, they attacked and fell into the hands of pirates.

Later, the pirates would use torture every day to force them to ask about the airship, and then there was no need to talk about it, Yuan Fang didn't ask, the agency of the airship, the dark night, didn't know more than the others, even if some of them couldn't bear the torture, they couldn't say anything, and even if the pirates knew about the fog stone, it didn't matter, now, the fog stone was no longer a secret.

Ren Fei woke up, Yuan Fang hurried over, and without waiting for Yuan Fang to speak, Ren Fei couldn't wait to tell Yuan Fang the news he had.

After hearing this, Yuan Fang asked Ren Fei to have a good rest, and Ren Fei closed his eyes with relief and fell asleep.

On the edge of the island, Yuan Fang stood on the beach, looking at the sea with a cool sea breeze, his thoughts fluctuated in his heart, and he was a little overwhelmed.

There is not much news that Ren Fei brought back, most of which Yuan Fang already knew, for example, the Wanliu Empire began to develop airships a few months ago, and now it has begun to take shape, Ren Fei also found out the approximate location of Changqing and Changqingdao, it stands to reason that Ren Fei can send these news back to the Dongsheng Empire through secret channels, and the reason why Ren Fei returned in person and brought his liaison was because he found that the Wanliu Empire had clearly grasped their identities and whereabouts, so he decided to retreat.

At that time, Ren Fei also notified the other liaisons, but he didn't know if those people had escaped, although Ren Fei didn't say it, but Yuan Fang could see that Ren Fei suspected that something was wrong inside the dark night, otherwise, even if the counterintelligence ability of the Wanliu Empire was strong, it would be impossible to grasp the movements of all of them in such a short period of time.

After a long time, Yuyue really couldn't stand this oppressive atmosphere: "Brother-in-law, is there anything to worry about?" ”
