This day was the first day that the experimenters were vaccinated with the smallpox virus, and just in case, Zhu Ying stayed at the experimental base all day.

Fortunately, everyone's physical condition is good, and there are no problems.

Zhu Yingneng guessed how excited his uncle Lan Yu would be today.

He also thought that Lao Zhu might talk to Lan Yu.

At this time, Lan Yu was as anxious as an ant on a hot pot.

However, Zhu Ying plans to go over to him tomorrow.

The next morning, the subjects woke up.

As the first person to be vaccinated with smallpox virus, Meng Hu carried the smallpox virus in his body and had successfully survived the day and night.

During those twenty-four hours, his body did not react in any way.

This amazed everyone, especially Imperial Physician Chen.

As a veteran physician with rich medical experience, he was honored to be able to participate in this experiment and witness the miracle happen.

If nothing else, this revolutionary experiment will be published in a few days.

The experimenters were also happy that they would soon be able to start their new lives.

Smallpox not only did not threaten their lives, but because of it, they were pardoned and regained their freedom.

No one could understand how Ying Gongzi, who single-handedly planned this experiment, learned that the cowpox virus was able to protect against the smallpox virus.

For them, the identity of Young Son is a mystery.

He wasn't even ten years old, and there was so much to understand.

After eating, Zhu Ying asked Wei Qing to accompany him to the Blue Mansion.

If you don't go, Lan Yu will die in a hurry.

Like last time, Zhu Ying came to the Blue Mansion by carriage.

However, this time he only brought Wei Qing alone.

Zhu Ying has been vaccinated with the vaccinia virus for a few days, and the wound has scabbed over and is about to heal.

In the past few days, his body has been fine, and Wei Qing and Imperial Doctor Chen are more relieved.

There were two new guards at the gate of the Lan Mansion, and they knelt down and saluted as soon as they saw Zhu Ying.

"The little ones have seen His Royal Highness Taisun!"

Zhu Ying smiled.

"Hurry up! Neither of you have seen me? How do I know who I am? ”

"Back to His Royal Highness Taisun, the Hou Ye has already told the little ones about the appearance of His Royal Highness the Taisun and Lord Wei, and instructed the little ones to bring them directly into the mansion when they see you two!"

"I see!"

"Your Highness, please come with me!"

One doorman led Zhu Ying and Wei Qing into the Blue Mansion, while the other doorman hurriedly ran in to inform their Hou Ye.

Before Zhu Ying could reach the living room, he saw Lan Yu hurrying towards him.

"Oops! My precious grandson, you're finally here! Grandpa is waiting to death! ”

"Grandpa, what are you anxious about?! Is it your stuff that can run away? ”

"Yes! Hahahaha......"

Lan Yu exchanged a few words with Wei Qing, and then asked him to be taken to the living room to make tea and snacks for him.

Then, he took Zhu Ying to his room, closed the door, and ordered no one to disturb him.

Zhu Ying joked:

"Uncle, I'm not your little daughter-in-law who hasn't seen you for a long time, why are you so excited?"

"Haha! Good grandson, I won't tell you, grandpa didn't sleep well all night, just waiting to see you! ”

"Grandpa, you didn't take what I said seriously the day before yesterday, and now you believe it, right?"

Lan Yu couldn't hide the joy in her heart.

"Good grandson! You're a god! Grandpa believed it! Now I believe everything! I didn't expect that your prophecies about me and Master Fu really came true! Ha ha! ”

As she spoke, Lan Yu's face changed.

"Good grandson, grandpa told you something, don't be angry!"

"Needless to say, I guessed it all! Did you tell my grandfather all the conversations between the two of us? ”

Lan Yu smiled awkwardly.

"Ying'er is so smart! Even these are known. However, I didn't tell him completely! ”

"Actually, it doesn't matter, grandpa will find out sooner or later!"

"Well, that's good!"

Lan Yu stroked his full beard, and then he was about to get down to business.

"Good grandson, tell grandpa what will happen in the next few years? In which year was my grandfather worshiped as the general of the expedition to the North University, and how did he win? ”

"Hehe, just because of this, you've been thinking about it all night, right?"

"Yes! Grandpa really can't figure it out, how can Your Majesty worship me as a general? Aren't there other famous generals such as Xu Da, Li Wenzhong, Feng Sheng, Chang Mao, and Fu Youde above me? How can it be my turn? ”

Zhu Ying took a sip of water and cleared her throat.

"Grandpa, what should I tell you? First, the imperial grandfather intends to cultivate you. Second, you are a son of luck, and when the opportunity comes, you can't stop it! Ha ha! ”

Next, Zhu Ying told Lan Yu a history that happened in another time and space.

Lan Yu, as Chang Yuchun's brother-in-law, although he had already entered the military, he was really awarded a knighthood after the founding of the Ming Dynasty.

In addition, in the early years of the Ming Dynasty, famous generals were like clouds, and Lan Yu repeatedly served as the vanguard of Fu Youde, Xu Da, Mu Ying and others, which shows that Lao Zhu is willing to give Lan Yu a chance and intends to cultivate Lan Yu.

Although Lan Yu has some military talents, he has also been trained by Lao Zhu.

In the seventeenth year of Hongwu, Li Wenzhong died of illness, and another year later, Xu Da died of illness.

Coupled with Deng Yu, who died of illness before, among the six founding princes of the Ming Dynasty, only Feng Sheng and Chang Mao were left.

Therefore, in the twentieth year of Hongwu, Lao Zhu sent Feng Sheng as the general of the conquest, and Chang Mao and Lan Yu as deputy generals to lead the Northern Expedition of 200,000 troops.

With the assistance of Lan Yu, Feng Sheng recruited Naha, the captain of the Northern Yuan Dynasty, without spending a single soldier, and incorporated the 200,000 soldiers and horses of Naha into the command of the Ming Dynasty.

However, due to the conflict between Feng Sheng and his son-in-law Chang Mao, Lao Zhu slapped each of them, and in the end, Lan Yu benefited.

After this, Lan Yu was awarded the title of "Great General" by Lao Zhu and won several more battles.

After the return of the three armies, Feng Sheng and Chang Mao were demoted one after another, and only Lan Yu was rewarded.

Lan Yu thus became Lao Zhu's candidate for the coach of the next Northern Expedition.

In the second year, that is, the twenty-first year of Hongwu, Lan Yu ushered in the peak of his life.

This year, Lao Zhu finally found out the news of the Yuan Lord and decided to go on another northern expedition, and Lan Yu was worshiped as a general, commanding 150,000 troops out of the customs.

Lan Yu Xingxing rushed to the north at night, until he reached the vicinity of the fishing sea, but he did not encounter a single Mongolian soldier and horse.

At the suggestion of the deputy general Wang Bi, Lan Yu led the army to continue to go deeper, letting the army dig holes in the ground and hide them on the spot, without making open fires, and hiding their traces first.

Soon after, the main force of the enemy army was found 80 miles to the northeast, and Lan Yu immediately ordered to gallop into the enemy camp while the wind and sand were dark.

The generals were killed in the dark, the Yuan Lord fled with the eldest son Tian Bao Nu and more than a dozen others, and Lan Yu captured the Yuan Lord's second son Di Bao Nu and the Yuan Lord's concubines, princesses, hundreds of people, and more than 70,000 other people, and obtained countless spoils.

In order to completely defeat the Mongols, Lao Zhu successively sent Xu Da, Feng Sheng, Li Wenzhong, and Lan Yu to lead the Northern Expedition.

Among them, Xu Da completely drove Emperor Yuan Shun out of the Central Plains, which is of great significance.

Feng Sheng and Li Wenzhong went on a northern expedition to meet Wang Baobao and other Northern Yuan generals, weakening the strength of the Northern Yuan.

And Lan Yu's move completely destroyed the Northern Yuan, and the Northern Yuan has been in a slump since then.

Lao Zhu was overjoyed when he got the good news. Before Lan Yu returned to Beijing, he had already prepared a reward for Lan Yu.

Hearing this, Lan Yu was overjoyed.

"Good grandson, that's when I was made a duke this time?"

"That's right, after this battle, you were named the "Duke of Liangguo"! It's the cold one that's cold! ”

After hearing this, Lan Yu always felt that something was wrong.

"Good grandson, are you sure it's the word "cool"? ”

Zhu Ying smiled.

Originally, it wasn't that "cool", but because you did two things you shouldn't have done on the way back to Beijing, grandpa changed the word "liang" to "cool" in a fit of anger! ”

Lan Yu listened, and a chill ran down her spine.

"Good grandson, what have I done? Please show me the way! ”
