In April, Dou Rail broke the flying chief, beheaded the old head of the flying chief, captured thousands of flying chiefs, and moved nearly 10,000 of them out of Suishan.

Emei Mountain in midsummer, the scenery is pleasant.

Standing under the cloister of the Thunder God Temple, feeling the cool breeze in the valley is particularly comfortable.

Zheng Yanqing opened his arms and breathed hard a breath of fresh air circulating in the corridor, only to feel that his mind was clear, and his spirit was uplifted.

It's been a month since the Flying Heads rebelled!

On the side of Yuewang County, after the grain road was calmed, Yujuluo and Duan Zhongkui led the snake out of the hole and beat Feishanman in Yangshan Town. With 3,000 officers and troops, after defeating more than 10,000 Feishan barbarians, Yujuluo even captured the Feishan barbarians in front of the battle, making the Yue Wang barbarians and the dragons leaderless.

Duan Zhongkui took advantage of the situation to wave his army south, and after breaking through the twenty-one barbarians in a row, the Yuewang barbarians surrendered.

However, these have little to do with Zheng Yanqing. After assisting Dou Railsheng to capture the bones and rescue Duoduo, in order to avoid unnecessary trouble, Yan Qing took Pei Cuiyun, Duoduo and Xionghai back to Emei Mountain. As for the Rongle City Grange, it is taken care of by Xu Xingbo, so naturally there is no need for him to worry about it. But among the entourage, there is one more person, who is Yan Qingxi's friend, Dou Fengjie.

Dou Liang wanted to start using troops against the flying chief, so he naturally didn't want Dou Fengjie to fall into danger.

Military merits are indispensable to Dou Fengjie. But if it allows him to avoid some dangers, it should be less dangerous. It just so happened that Yanqing was going to return to Emei Mountain. And Dou Fengjie couldn't bear to be separated from Yanqing, so Dou Rail pushed the boat down the river and asked Yanqing to take Dou Fengjie up the mountain together.

Dou Fengjie followed Yanqing, and Dou Liang was very relieved.

But in Yan Qing's eyes, it is clear that this old man wants him to be Dou Fengjie's nanny.

After returning to the mountain, Wujian was naturally very happy.

With two more sisters who love her, and there are people around her to talk to, of course she is very happy. As for Qing, after returning to the mountain, it became extremely mysterious. I got together with Zhao Xichen all day, muttering and muttering I didn't know what I was talking about. Originally, the relationship between Zhao Xichen and Zheng Yanqing was not very close, but I don't know why, this time he seemed very affectionate and had no sense of rejection.

Zheng Yanqing made a few chest expansion movements on the corridor, and saw Xiong Dahai running from the other end of the corridor.

"Brother, that madman Zhao said he was ready!"

"Well, let's get over it."

When Zheng Yanqing heard this, he immediately came to his senses.

He and Xiong Dahai hurriedly left the Thunder God Temple and ran out of the mountain gate.

Pei Cuiyun, who was walking in the courtyard, saw his mysterious appearance, and couldn't help but ask curiously, "Yanqing, where are you going?" ”

"Oh, do an experiment with Zhao Zhenren."

Yan Qing didn't look back, and rushed out of the mountain gate.

Pei Cuiyun followed curiously, and the three of them followed the rugged mountain path, and soon came to a remote mountain valley located below the Thunder God Temple. I saw that Zhao Xichen was already waiting in the valley, and when he saw Yanqing coming, he hurriedly ran up, looking nervous and excited.

"Zhao Zhenren, are you ready?"

"Eun!"

Zhao Xichen nodded again and again, then pointed to a pile of gravel in the middle of the valley, and said softly: "It's all done, it's just the last fire." ”

Yan Qing also seemed a little excited, and motioned for Xiong Dahai to protect Pei Cuiyun and retreat.

He and Zhao Xichen picked up a jar full of tung oil, looked at each other, started from the pile of gravel, carefully poured out the tung oil, and then slowly retreated to the mouth of the valley. Exiting a distance of about ten meters, the tung oil is also depleted.

"Zhao Zhenren, you go back!"

Zheng Yanqing commanded, Zhao Xichen nodded hurriedly, and retreated towards Gukou.

Qing Ze took out a fire fold from a wolf skin pouch that straddled his waist, then rubbed the fire and threw it on the tung oil.

I saw that after he threw away the fire fold, he immediately turned around and ran.

The fire broke and ignited the tung oil, and a line of fire quickly spread towards the gravel pile, and soon reached the gravel pile. Tung oil was also poured on the gravel pile, and it burned all at once.

Yan Qing ran to the mouth of the valley, stopped, and turned his head to look at the pile of burning rubble, full of anticipation.

This is what he and Zhao Xichen are muttering about.

It's a pity that he is not from a chemical background, except that he knows that gunpowder is composed of sulfur, carbon, and saltpeter, and he doesn't know anything about the specific ratio and the corresponding various auxiliary ingredients. He can only make some suggestions based on his impressions.

Sometimes, he even feels that he is not as good as Zhao Xichen.

Earlier, Zhao Xichen said that he had succeeded in drumming up.

Yan Qing and he were very excited and couldn't wait to do an experiment. The valley below the Temple of Thunder was chosen because it was remote and inaccessible. So they chose to do experiments here, but they saw the fire raging, but the gunpowder buried under the rubble did not seem to have any reaction. Zheng Yanqing's eager heart gradually cooled down, and his brows couldn't help frowning.

"Zhao Zhenren, it doesn't seem to work."

Zhao Xichen also looked lost, shook his head and said, "I just mixed the gunpowder in the jar as you said." It stands to reason that it should have sounded at this time...... Why is there no movement? ”

"In a jar?"

Zheng Yanqing was stunned for a moment, and hurriedly asked, "Then can you put a fire-starting thing on the jar?" ”

"Well...... Zhao Xichen scratched his head, "It doesn't seem to be." ”

"If you don't put something that ignites fire, how can it work." Zheng Yanqing said angrily, and was about to go to the valley. But at this moment, I heard a loud bang, a huge wave of sound, and a thick smoke, mixed with the pungent smell of gunpowder, rose into the sky and spread rapidly.

Zheng Yanqing was caught off guard and sat on the ground.

Looking at Pei Cuiyun again, she was pale with fright by this sudden loud noise.

"Ringing, ringing......"

Zhao Xichen's ears were buzzing, and he shouted.

Zheng Yanqing is not much better than him, he is also dazed, and his ears are ringing non-stop.

Did it blow up?

He didn't even stand up and looked forward excitedly. But I saw that the pile of rubble was scattered all over the ground, and the sound was very loud, very amazing, but the effect was ...... It was only the rubble that rolled down from the stone pile, and most of them were not far away, except for a few that burst out.

And the gravel at the bottom is even more immovable.

Yan Qing was extremely surprised in his heart, and walked forward quickly, looking at the mess on the ground, showing a look of disappointment.

It wasn't what he had imagined it to be, it wasn't powerful at all. It's just a little louder, but if it hurts, it's unlikely.

"We made it!"

Zhao Xichen was ecstatic.

Perhaps, in his opinion, he succeeded...... But Zheng Yanqing couldn't cry or laugh: What kind of success is this? It's useless at all, where can it be called success?

Just looking at Zhao Xichen's ecstatic appearance, he really didn't want to hit his positive surname in the past. Scratching his head, he slowly walked out of the valley.

Pei Cuiyun stepped forward, "Yanqing, what was the movement just now?" ”

"Nothing...... Just a failed experiment. ”

"Failure?" Zhao Xichen also regained his hearing at this time, and shouted with some anger: "Obviously succeeded, how can you say that you failed?" ”

"When I say failure, I mean failure."

Yan Qing muttered a sentence and left without looking back.

Zhao Xichen looked at Yan Qing's back and shouted loudly: "Zheng Yanqing, you said why, where did I fail!" ”

However, Yan Qing ignored him.

That night, Zheng Yanqing recovered from his lost emotions.

He also knew that for Zhao Xichen, the appearance of gunpowder was actually a huge invention. Historically, gunpowder only appeared in the late Tang Dynasty, and then after countless repeated research, it began to be used in military affairs during the Northern Song Dynasty.

It is obviously unlikely that this will advance from invention to specific application.

Yan Qing found Zhao Xichen, apologized to him first, and then told Zhao Xichen about the use of gunpowder he envisioned.

Zhao Xichen heard this, and couldn't help but be stunned!

The idea was too far ahead of its time, too weird.

For a while, he may not be able to digest it. However, in this way, it also explains the reason for Yan Qing's emotional gaffe. It's not that Yan Qing's eyes are red, but that his requirements are too high. Yanqing's requirements, for the current Zhao Xichen, are three hundred years ahead.

"Zheng Yanqing, just rest assured, I will definitely be able to get what you want."

Zhao Xichen swore an oath, and Zheng Yanqing could only smile and laugh, and it was hard to say anything. After all, he knew in his heart that his requirements for Zhao Xichen were a little too harsh.

Said that the child was back to normal.

After Dou Liang eliminated the flying chief, as he had promised before, he did not pursue Gu Siman's charges again.

At the same time, there were frequent reports of good news in Yuewang County, and the war was about to end. Speaking of which, this was not an equal war in the first place, and although the Yue Wangban was belligerent and ferocious, it was obviously difficult to compete with the well-trained officers and soldiers. Moreover, with the experienced and equally brave and invincible Yu Juluo as the commander, and the resourceful and skilled Duan Zhongkui, how can the barbarian army stop the footsteps of the official army.

The condition of the innocent has also been further controlled.

Sun Simiao has developed a simple set of health preservation techniques, combined with food, acupuncture and medicine, a four-pronged approach. In Sun Simiao's words, in another two or three years, he will be sure to eradicate qi disease for Wuji. Of course, in this, Yanqing's stethoscope also played a big role.

Day by day, in the blink of an eye, it is June.

Calculating the time, it has been more than a year since I went up the mountain to treat the disease.

And Zheng Yanqing's fourteen-year-old birth is also coming.

At the age of fourteen, if this is in Luoyang, Yan Qing will be ready to enter the official school and practice. However, it is estimated that no official school is willing to accept him, after all, the fame is there, and it doesn't seem appropriate for you to let anyone be his teacher. It's better to stay in the mountains, and it's leisurely.

But Zheng Yanqing is a little homesick...... I haven't been back for almost two years, I don't know how my grandfather is doing in Gong County, how is he doing now?

This homesickness came out all his life, and Yan Qing looked listless for a few days. Duoduo and Pei Cuiyun understand his thoughts, Duoduo is okay to say, she has been floating in all directions since she was a child, and she doesn't know where her hometown is. But Pei Cuiyun also began to miss her relatives at home.

Not only Cuiyun, but also Innocent.

Yan Qing found that his emotions had been able to affect many people unconsciously, so he hurriedly cheered up and tried to make everyone happy.

This time, outside Emei Mountain, it is very hot.

But in the mountains, the wind is light and the clouds are light, and there is a cool atmosphere.

Zheng Yanqing practiced kung fu and sat on the steps of the corridor with Xiongdahai, chatting without a word.

Sun Simiao was not in the Thunder God Temple, and went into the mountain to collect medicine. Zhao Xichen is also not in the Thunder God Temple, it is said that he went down the mountain to Jiajiang to visit a friend.

Bathed in the cool mountain breeze, Yanqing was a little sleepy.

He got up and was about to go back to his room to rest, but he saw Wujian walking in a hurry and looked panicked.

"Brother Yanqing, Brother Yanqing is not good...... There are a lot of people coming down from the mountain, and they are still holding weapons, and they are coming to us. ”

When Zheng Yanqing heard this, he immediately stopped.

At this time, who found the mountain?
