Tian Xing was willing to go down the mountain with Danyangzi Wang Boyang, naturally because of the words of the dragon girl Cai'er, and if he mastered the knowledge of chemistry, he could prepare fertilizer that would increase grain production by more than five times.

As a farmer's heir, he naturally attaches great importance to farming. Otherwise, if you don't practice optical agriculture, what's the use of learning it?

It's just that Tian Xing thought about it afterwards, and he seemed to be too impulsive. Even if the dragon god teaches divine arts, it seems unlikely that he wants to increase grain production by more than five times?

Since the advent of the Hundred Saints, it has a history of 1,000 years. Over the past millennium, farming techniques have been developed, but food production has not even doubled.

But now that I have studied chemistry, I can have something that can increase the growth of grain by five times, and Tian Xing thinks that it is impossible. But since everyone is here, they come to listen to Su Ziheng's lecture with the attitude of listening and listening.

Unexpectedly, he found that a person who he had never imagined before would appear in this remote mountain village.

Seeing that Jia Qingwen didn't seem to remember who he was, Tian Xing took two steps forward, walked up to him, and said with a smile: "Farmer Tian Xing, I have seen Brother Jia." ”

Jia Qingwen reacted at this time, and said with a guilty face: "I don't know if it's Brother Tian in person, Jia is really rude, and I hope Brother Tian is not strange." ”

Tian Xing shook his head and said with a smile: "They are both fallen people at the end of the world, Brother Jia doesn't have to mind, I haven't seen each other for nearly ten years in a blink of an eye, and their appearance has changed a lot, and they can't recognize each other for a while, which is normal." ”

Jia Qingwen smiled, as if he didn't want to mention more about the past, so he changed the topic and asked, "Why did Brother Tian come to Bailu Academy?" ”

Tian Xing laughed, and told Jia Qingwen about his coming to Sujiazhuang.

After listening to this, Jia Qingwen didn't make a conclusion, but pointed out: "Brother Tian, this Bailu Academy Mountain Leader Su Ziheng, don't look at his young age, but what he has learned is extraordinary. And there are often extraordinary acts, since Brother Tian is here, you might as well listen to it more, maybe there will be an unexpected gain. ”

Tian Xing nodded when he heard this, and echoed in a loud voice: "What Brother Jia said is true, and he won't talk about anything else. The four basic mathematical operations I heard today are worth it. ”

Jia Qingwen invited with a smile: "It's better to meet by chance, it's rare to meet an old man in Xiliang, it's better to go to the place where Jia stays and sit." ”

Tian Xing arched his hand and smiled: "I don't dare to ask for it." ”

Jia Qingwen taught in Bailu Academy, and Su Ziheng specially arranged a courtyard for him, which was originally the place where the gentlemen who taught in Bailu Academy stayed before, but then the academy declined, and the gentlemen were all gone.

For the time being, Su Ziheng only hired Jia Qingwen to teach, so the entire courtyard was occupied by him and Yang Lun. Su Ziheng originally saw that Jia Qingwen's legs and feet were inconvenient, and he planned to arrange a maid to serve him, but Jia Qingwen refused, saying that Yang Lun alone was enough, and the disciples would serve him.

After entering the courtyard, Jia Qingwen instructed Yang Lun to boil water to make tea, and he smiled at Tian Xing, "The place is simple, and I hope Brother Tian doesn't mind." Jia also borrowed to live here, but he didn't put too much effort into decorating. ”

Tian Xing looked around, the room was not very big, it was very simple and clean, there were a few books and pen, ink, paper and inkstone on the desk by the window, an oil lamp was resting on the table, and the dim flames were constantly jumping, adding some light to the room.

Tian Xing said enviously: "Thousands of acres of good land, but three meals a day; There are thousands of mansions, but they are a dream. If you can live, what's simple? What's more, you can sleep with a book day and night, which is a life that many people can't ask for. ”

Jia Qingwen laughed and said: "Brother Tian is still so free and easy, this heart is extraordinary, this is the real envy." ”

At this time, Yang Lun walked in from outside with a teacup and said respectfully, "Two gentlemen, please use tea." ”

Tian Xing took the teacup, nodded at him and smiled: "Thank you for this little brother, is the little brother a new disciple of Brother Jia?" ”

Jia Qingwen smiled, and Lao Huai said with relief: "Yes, this is exactly the disciple that Jia has accepted in recent years. How about Brother Tian help take a look? ”

Tian Xing put down the teacup, looked Yang Lun up and down, and praised: "With a good appearance and a resolute appearance, he is indeed a good seedling, and it is worth cultivating." ”

Although Tian Xing is a farmer's heir, his physiognomy is not inferior to that of the Yin and Yang family.

"It's just...... Brother Jia really plans to teach and educate people in the future, live in peace, and never go out of the mountains again? ”

The smile on Jia Qingwen's face suddenly disappeared, he reached out and patted his crippled thigh, and laughed at himself: "Brother Tian thinks that I am like this, can I still do anything?" My vertical and horizontal faction is different from Brother Tian's farm, relying on the kung fu of the mouth and a pair of feet that can walk the world. ”

"Now that I'm struggling to walk, who else would hire a cripple like me as a lobbyist?"

Tian Xing was silent, and only sighed faintly after a long time: "Could it be that Brother Jia really didn't think about returning to Great Wei one day?" Can some hatreds really be put down and never remembered again? ”

Jia Qingwen's face showed a meaningful expression, and he gently played with the teacup in his hand, and said with a smile: "Who can say clearly about the future, the key is to grasp the present." ”

Tian Xing's physiognomy is good, but after all, he has had too short contact with Su Ziheng and does not really realize Su Ziheng's ability. And he is different, through this month's observation, he has deeply seen his difference, and the next thing to do is how to improve his status in his mind, so that he knows where his ability lies.

Only useful people can get the attention of the other party!

……

Under the command of Bo Yalun, the Mengyuan cavalry of Sichuan County was divided into three teams. Among them, 3,000 people guarded Sichuan County, and the other 3,000 soldiers divided into two routes to defraud Kang County and Ding County respectively.

Bo Yalun is not very demanding, whether it is Kang County or Dingxian County, if he captures a county seat at will, the 190,000 Mengyuan soldiers at the border can drive straight into the hinterland of Xiliang.

Therefore, she specially explained that once the opportunity is taken, even if it is at any cost, she will seize a city gate, and then release a signal to wait for the arrival of Munch's army.

According to the task assigned by Bo Yalun in advance, Yuechi Cha'er chose to go to Kang County to carry out the fraud city. Yesterday evening, when he was defrauding Sichuan County, he was almost ruined by a soldier from Kang County who asked for help.

Afterwards, Bo Yalun captured the soldier alive, and originally wanted to pry some information out of his mouth, but he died of serious injuries.

Although he couldn't get any effective information, Yuechi Cha'er relied on a few letters from the soldier, and after learning about the situation in Kang County, he carefully arranged the plan, and took advantage of the dawn of the day, the defenders of Kang County did not react in time, and captured the city gate of Kang County in one fell swoop, with less than 2,000 men and horses, and held on to the city gate until Meng Ke commanded the army to break through the city.

On the other hand, the luck was much worse, when he was deceived by Liu Yuan, the magistrate of Dingxian County, he saw through it, and the commander of the army was shot dead at the gate of the city on the spot.
