After taking care of the wounds on the horse's hooves, Li Changfeng left, while Chunni stayed in the stable to observe the changes in the horses.

Zhang Haihui had already come to the mansion, and Li Changfeng instructed him to personally bring a group of masters to Baishi City, and bring Tang Yi and many other scientists who were still in Baishi City back to the capital.

These people are too important.

He is not at ease in Baishi City, if he is in the capital, he and Emperor Qianwu's army will protect him, and there will be no problems.

Such an important task naturally has to be entrusted to someone you trust.

At the same time, he ordered the start of construction of a new plant for the mass production of penicillin.

Then Li Changfeng rode a fast horse to the glass products factory of the scientific research institute outside the capital.

He gathered the best glass craftsmen in the factory and asked them to make a batch of better syringes, and those syringes sent by Tang Yi were too rough.

By the time I returned to the mansion after making these arrangements, it was almost dark.

Li Changfeng didn't care about eating, so he walked quickly to the stable, and found that Chunni was still sitting there observing the horses.

"How's it going?"

Chunni raised his head, his tone was no longer as calm as usual, and exclaimed: "It really works, this horse is much more energetic, and he even ate a little grass and drank some water just now!" ”

Li Changfeng laughed: "Okay! That's great! ”

Chunni got up, stared at Li Changfeng with beautiful eyes, and asked in disbelief: "You also invented this penicillin?" ”

"That's right, I invented it, but the follow-up improvement of purification technology to achieve mass production was done by the people of this prince."

"You...... You ......" Chunni's seductive red lips opened and opened, his face full of shock, and he didn't know what to say for a while.

"Don't you, go, it's time to eat."

Li Changfeng was in a good mood, and walked towards the restaurant with Chunni in tow, always disgusted with the man's touching her Chunni, but at this time he didn't resist and let him pull it.

"You're such a ...... Well, how to say, a very amazing person, I wonder, how do you know this? ”

"Some people are born to know, do you believe it or not?" Li Changfeng said with a smile.

"It can't be." Chunni shook his head, not believing that such a person existed.

"Well, to tell you the truth, this prince discovered these things on a flash of inspiration while observing things."

"Can you tell me how penicillin is made?"

"No, it's a secret, it's like you didn't tell me about Bai Yujing's situation."

Chunni stopped talking, looked at Li Changfeng's eyes with brilliance, and became even more curious about him in his heart.

……

Day 2.

Li Changfeng got up early, went to the stable after breakfast, and found that Chunni was also there, and was stunned to look at the horses that had stood up and ate grass in the manger.

Li Changfeng laughed a few times, turned around and left, sent someone to get into the carriage, and walked towards the palace.

Many of the defenders of the northern border were wounded and inflamed, and it would not be long before they died, and penicillin could be used to save their lives.

Li Changfeng didn't plan to ask for a penny.

He had great respect for these soldiers who defended the country, and he couldn't bear to see them die, and the current treasury was very tight, and he would have to pay more silver for railway construction in the future.

That little bit of money was nothing to him.

Of course, he also has a little selfishness.

That is, advertising penicillin by treating these fighters, and the shocking effect of this batch treatment is much stronger than finding a single patient.

When penicillin became famous all over the world, it was the beginning of his money.

……

Li Changfeng was the only one in the entire Great Qian, who could directly enter the imperial study of Emperor Qianwu without the need for communication.

"Father, the son has recently made a ......"

Li Changfeng pushed the door in, and stopped before he finished speaking.

I saw Feng Quji, Ye Qingcang, Yue Jianghe, Chen Dingyuan, and several other generals in the army sitting in the imperial study, all of whom were not very good-looking.

After Emperor Qianwu sat on the imperial case, his expression was gloomy.

Feng Qujian and the others hurriedly got up to pay respects.

"Meet His Royal Highness the Nine Emperors."

"Please get up, father, since you have something to discuss, then the ministers will step down first and go to Jingren Palace to see the queen mother, and then come back."

After speaking, Li Changfeng didn't care whether Emperor Qianwu agreed or not, and turned around and left quickly.

Looking at the battle, he knew that something big must have happened, he didn't want to participate in the discussion, what if Emperor Qianwu sent him another job?

How could Emperor Qianwu not understand what kind of temperament his son was, he didn't have to think about it to know Li Changfeng's thoughts, and he was angry in his heart.

Can't you worry about me?

"Stop!" Emperor Qianwu scolded with a calm face.

Li Changfeng had no choice but to stop.

"What does my father command?"

After all, there were so many ministers at the scene, Emperor Qianwu didn't continue to scold Li Changfeng because he was afraid of Li Changfeng's face, and said in a deep voice: "You came just in time, I originally planned to summon you, sit down." ”

Emperor Qianwu pointed to the chair, then looked at Gao Dali.

"Tell him about the situation."

Gao Dali bowed slightly, and was about to speak, but was preempted by Ye Qingcang.

"Forget it, I'll just say it."

Ye Qingcang looked at Li Changfeng with a solemn expression.

"The northern border is urgent, the northern border guard Sun Xueyi is seriously injured, the generalissimo of the Northern Expedition Li Jianye is losing his troops and generals, and the northern border is in danger!"

"How is this possible?!"

Li Changfeng exclaimed.

He couldn't believe that Li Jianye would lose his troops.

On this expedition, there were 200 artillery pieces, 500 muskets, plenty of ammunition, and every soldier had a wealth of combat experience.

The strength of the artillery battalion and the musket battalion is much stronger than when he was in the southern expedition, and with such a strong strength, even if he does not achieve proud results, he should not lose his troops.

This is so unreasonable.

Ye Qingcang sighed: "When I first heard the news, the old minister didn't believe it, but that's the case, but this matter can't be blamed entirely on His Royal Highness Li Jianye......

Next, Ye Qingcang analyzed the battle in the north from a professional military perspective.

The northern border is connected to the Hu grassland, and there is no danger to defend the Pingchuan, which can be said to be a lonely city, and Sun Xueyi used to drive the Hu army that came to invade the border by way of pursuit warfare.

The cannon body is quite cumbersome, and although Li Changfeng has already installed wheels, the movement speed is still too slow, especially on the grassland.

Therefore, Li Jianye adopted the tactics of Li Changfeng in southern Xinjiang and stuck to the city wall.

However, the Hu army was cunning, and after a siege battle, it gave up the siege after heavy losses, spared the city and drove straight into the territory of Daqian.

Li Jianye had no choice but to lead the army in pursuit, and the artillery was useless, but the 500 muskets could not form an effective combat effectiveness.

Although there were grenades to help, the Hu army was not afraid of death and was good at riding and shooting, and with the help of treacherous beasts, it caused serious losses to the Daqian army.

Of course, the losses of the Hu army were not small.

The Hu army cannot defeat the Daqian army, and the Daqian army cannot destroy the Hu army.

The war is in a stalemate.
