Li Zhi felt that it was a serious mistake to make mahjong.

Because since Li Yuan learned to play mahjong, he is no longer willing to exercise.

Every day, he tries to pull others to play cards with him.

Sometimes, even eating is a hasty bite and then sitting down at the table again.

After a few days, Li Zhi finally couldn't take it anymore.

He strongly demanded that Li Yuan must exercise three times a day, and each time it should not be less than half an hour, even if it was a walk.

It was only then that Li Zhi noticed a very terrible thing.

That is, there are too few entertainment items in this era.

So much so that many of the people of Datang are good at gambling.

They love cockfighting, dog fighting, cricket fighting, and they love to play dice.

Li Zhi walked around the city of Guangzhou for two days and found that people from all walks of life would gamble twice when they were free.

Even among the military officers and the military, gambling was very popular.

Although there were regulations prohibiting gambling in the imperial court, it was clear that such regulations were not strictly enforced.

In Li Zhi's view, this is not a good thing.

The harm of gambling is huge, it will destroy the stability and harmony of society, and let people form the value of getting something for nothing.

It can also lead to family breakdowns, and even major cases such as robbery, theft, and homicide due to high debts.

The most important thing is that Li Zhi knows that gambling is still the main way to breed corruption, and even he often does it himself.

Thinking of this, Li Zhi was a little uneasy.

He felt the need to change the situation.

At the very least, some positive games should be invented to alleviate this phenomenon.

Fortunately, both petrochemical and rubber have achieved some research results.

This makes it possible for many popular games in the previous life to be popularized.

So Li Zhi hurriedly wrote a letter to Li Su, asking him to lead people to develop football, billiards, basketball, volleyball and table tennis.

For this reason, he also carefully recalled in his mind the knowledge of chemistry in high school.

Along these lines, he also thought of an extremely important fishing implement.

That's the rubber fishing net.

The fishing nets used in this era were still woven from hemp rope.

The hemp rope is not only heavy on its own, but also rots quickly once it is soaked in water.

As a result, the nets are not only small in size but also often need to be dried.

As a result, the utilization rate of fishing nets is also very low, and it is not even as many fish as caught using harpoons, baskets, etc.

Rubber wire fishing nets have no such drawbacks at all.

Not only is it lightweight and durable, but it can also be made very large.

This makes fishing much more efficient.

If we build a complete supply chain for fishermen.

Then the people of Datang no longer need to put only wild vegetables and pickles on the table.

After Li Su received Li Zhi's letter, he immediately led people to get busy.

It is easy to say in other aspects, mainly because the manufacturing process and equipment of these things also need to cooperate with Yan Lide and others.

With the manpower they have now, this will be another difficult task.

Li Zhi was trying to improve the material and spiritual enjoyment of the people.

And Sun Simiao led the teachers and students of the medical school to work hard for the health of the people.

Unlike the college run by Li Zhi, who was always distressed by admissions problems.

Datang Medical College is getting bigger and bigger with the policy support of the imperial court.

Under such circumstances, Datang has ushered in an explosive improvement in medicine.

One of the most important findings is a strong argument for the dangers of consanguineous marriage.

Through a large number of investigations and animal experiments, the School of Medicine has proved that blood relatives and cousin unions within three generations will have an impact on future generations.

And when Li Shimin learned about this discovery, he was shocked into a cold sweat.

Because at this time he was preparing to implement a decree on the royal family.

That is, the man of the royal family must marry a woman of the descendant of the family, and the woman of the royal family must also marry the son of the family.

Once this policy is implemented, it will not be long before there will be many cases of consanguineous marriages in the royal family.

At that time, wouldn't it be easy for Li Tang's bloodline to be abnormal?

Li Shimin hurriedly called Sun Simiao and asked him, "Is the research on bloodline in the medical school really so terrifying?" ”

Sun Simiao opened his mouth and said, "Your Majesty, a large number of comparison results at the moment support the theory of the medical school. ”

Li Shimin asked again: "Is there a way to resolve it?" ”

Sun Simiao shook his head and said, "I haven't found any effective method for the time being. ”

After hearing this, Li Shimin sighed and said, "In this way, how can we maintain the noble bloodline of the royal family? ”

Sun Simiao hesitated for a moment and said, "Your Majesty, according to the research of the medical school, there is no difference between the royal bloodline and ordinary people. ”

After Li Shimin heard this, a fierce light immediately shot out of his eyes.

He stared at Sun Simiao coldly and said, "You have to pay attention to what the divine doctor says, how can the royal bloodline be the same as that of ordinary people?" ”

Sun Simiao was not afraid of Li Shimin's gaze.

He said in a flat voice: "Your Majesty, please forgive the old minister, according to the research of the medical school, this is indeed the case. ”

Li Shimin frowned immediately after hearing this.

It was very difficult for him to accept this result.

Because the emperors of the past dynasties were all from the big families, even after Chen Sheng and Wu Guang overthrew the Qin Dynasty, they were considered to be born with noble blood.

And this is why the Li family wants to do everything possible to associate themselves with Longxi Chengji.

This was both a worship of good blood and a political necessity for the ruler.

Because once the people realize that everyone can rely on their own efforts to fight for imperial power, it will be extremely detrimental to the rule of the Li family.

After a long silence, Li Shimin spoke: "Don't hype this matter for the time being, I still need to carefully weigh the implications. ”

Sun Simiao hesitated for a moment and bowed down and said, "Minister, obey the order." ”

Li Shimin saw Sun Simiao's hesitation.

So he sighed and explained: "This matter is about the majesty of imperial power, and once the people know that the royal family is no different from the public, it will bring great turmoil. ”

After listening to Li Shimin's explanation, Sun Simiao quickly figured out the key to it.

So he saluted again and hurried away.

He's going to hurry back and shut up everyone who knows about it.

Otherwise, they are likely to be killed because of this incident.

After Sun Simiao left, Li Shimin fell into contemplation alone.

He still finds it difficult to accept this fact.

The main thing is, if the royal family can't have a better bloodline, how can it maintain a long rule?

After a long time, Li Shimin failed to come up with an effective solution, so he had to write a letter to Li Yuan.

Tell him more about it.
