Only a small half of the sweet potatoes harvested by the Fang family this year were left, and the rest were all moved away by Li Er.

The farmers who were in charge of planting before were also taken away by Li Er, and they were given small official positions, just waiting for the next year to teach others to grow sweet potatoes.

The fire kang has also been vigorously promoted by Li Er.

The people didn't know what a kang was, but when they heard that people from the government said that building a kang would not freeze to death in winter, they began to build a kang at home.

The government has taught the people to build a fire kang, and before the arrival of winter, the people in Chang'an and some neighboring big cities have built a fire kang.

Poor families could only build a large kang with enough space for the family to sleep on.

The firewood was cut in the wilderness, and there was no need for money.

After a winter, very few people froze to death.

The people thanked the imperial court for letting them build a fire kang, and they set up immortal cards for Li Er.

Li Er's reputation is unprecedentedly strong, which makes him happy.

He now has prestige and food, and he has the confidence to argue with those families.

After Fang Xuanling gave Du Ruhui the credit for the fire kang, he also gave the credit for the cement to Li Jing.

Li Jing is also Fang Xuanling's friend, and accepted the credit that Fang Xuanling pushed over with a smile.

After that, Jia Huan didn't come up with any other technology.

First, the Tang Dynasty was still too backward, and many technologies could not be done with the current technology.

The second is not to let Li Er notice anything unusual.

Now the things he has taken out have improved Datang's national strength a lot, which is enough.

Jia Huan nested in the Fang family, while cultivating, he lived a salted fish life.

Once after Jia Huan showed his light skills in front of Fang Yiai, Fang Yiai shouted that he wanted to practice with Jia Huan.

The Fang family regarded light skills as the legendary flying heaven and earth technique, thinking that Jia Huan had obtained immortal fate and would definitely become an immortal in the future.

Fang Yiai was clamoring to cultivate immortals, and the Fang family did not stop him.

Jia Huan had no choice but to teach him a set of cultivation methods.

This set of methods is suitable for Fang Yiai's unstable temperament, and he can practice with more exercise.

This is what Jia Huan found from the storage bags of the misty real person and the vast master.

Jia Huan didn't know how far Fang Yiai would cultivate in the end, after all, this guy was a guy who liked to enjoy indefiniteness.

Who knows when he'll get bored and give up.

However, he didn't expect Fang Yiai to stick to it.

The rest of the Fang family also followed suit and learned this method, but only Fang Yiai insisted on cultivating.

Of course, this kind of cultivation method is not effective in the short term, and it is normal for others to see that it has no effect, and it is normal to give up.

They waited for Jia Huan to take them to fly.

If one person gains the Tao, the chicken and dog ascend to heaven.

Only Fang Yiai's nature is stubborn, and he feels that strength is the last word, so he insists on cultivating.

And so, five years passed.

Fang Yiai and Fang Yi are married.

Both of their wives are good women, and they get along harmoniously with the two brothers of the Fang family.

Fang Yiai was oppressed by his wife in his previous life, and his wife in this life was extremely gentle with him, which moved him to tears.

Such a woman is a good wife!

Comparing his wife in this life with Gao Yang, Fang Yiai felt that he had gone to heaven in this life.

Therefore, he was very good to his wife.

The feelings are mutual, he is good to his wife, and his wife is naturally good to him.

The relationship between the two husbands and wives is very harmonious, and they have been holding each other for three years.

With his wife and son by his side, Fang Yiai did not give up cultivation and continued to practice the exercises given to him by Jia Huan.

By this time, he had already faintly shown signs of entry.

Fang Yiai was very happy, and he worked harder in his cultivation.

Princess Gaoyang has also reached the age of marriage.

A year after the Fang Yihuan accident, Li Shimin lifted the ban on Princess Gaoyang.

Princess Gaoyang pretended to be clever to Li Shimin, and gradually restored Li Shimin's love for her.

Although it is not as good as before, at least Li Shimin has restored her status as a princess.

When she reaches her age, Li Shimin will also think about finding a good family for Princess Gaoyang.

It's just that because of Princess Gaoyang's previous operations, coupled with the Lu family's sparing efforts to help Princess Gaoyang publicize, the nobles in Chang'an City didn't want to marry Princess Gaoyang.

Those who are willing to marry Princess Gaoyang are all small nobles who want to borrow the identity of Princess Gaoyang.

Not to mention Princess Gaoyang, Li Shimin can't look down on such people.

Li Shimin had a headache for Princess Gaoyang's marriage, so he simply handed over this matter to Wei Guifei to deal with.

Wei Guifei took on such a thankless job, and she had a headache, so she could only try to help Princess Gaoyang find a good family.

In the end, she found a good candidate.

This man's name is Wu Yuanqing, and he is the son of Yingguo Gong Wushitong.

The samurai Tong has passed away, and the samurai brothers do not have their father's ability to support the lintel, and the samurai family is already a little down.

However, Wu Yuanqing has a good appearance, and he also has some literary and martial arts, and he is still quite able to make people.

The status is not low, compared to the sons and daughters of those small aristocratic families, it is simply standing out from the crowd.

As soon as Wei Guifei said that the candidate was chosen to Li Shimin, Li Shimin also thought it was good, so he ordered Gao Yang and Wu Yuanqing to marry.

After Princess Gaoyang knew the candidate, she went to see Wu Yuanqing and found that Wu Yuanqing looked good, and she was very satisfied.

Wu Yuanqing was also very satisfied with this marriage.

He's married to a princess!

Even if it is vicious and brutal?

Just coax it.

As long as he takes advantage of the princess's power to enter the sight of the emperor and the prince, be reused by the emperor and the prince, and restore the glory of the martial arts, he can bear it.

At most, a few more beautiful concubines will be accepted.

He didn't know that a woman like Princess Gaoyang could spend her own money, and she would never allow her husband to find another woman.

A few months later, Princess Gaoyang got married.

Just got married, both men and women are very satisfied, the relationship is good, and the concubine is in love.

At this time, Jia Huan appeared in Chang'an City wearing a Taoist robe, and was seen "unintentionally" by Fang Yiai.

Fang Yiai felt that this person was very similar to his missing brother, so he pulled the person to Fang's house.

Mrs. Fang's Lu Shi connected with her son's mother and son, and when she saw the little Taoist, she immediately recognized that this was her son.

Thus, mother and son, father and son, and brother recognized each other.

The youngest son of the Fang family, who thought he was dead, actually came back alive.

It turned out that the youngest son of the Fang family was rescued by an old Taoist priest after falling into the cliff.

And the Fang family lost his memory because he injured his brain when he fell, and he didn't know who his parents were, so he could only follow the old Taoist priest.

Now that the old Taoist priest has died, the Fang family children followed the clues to Chang'an to find their relatives.

Everyone thought it was too coincidental, Princess Gaoyang had just gotten married, and the youngest son of the Fang family came back, and they always felt that there was something strange in the middle.

Could it be that the boy from the Fang family had already recovered his memory, because he didn't want to marry Princess Gaoyang, so he waited for her to come back after she got married?
