In the Tang Dynasty, with Li Shimin as My Father

The protagonist is a bit too useless, especially with such a big hook, as if he has no brains.

The content here is a bit nonsense. Li Er's attitude toward the prince changed drastically after the prince became lame. In addition, the prince himself couldn't stand the pressure and acted recklessly, and his mentality exploded! The way Li Er came to the throne meant that he would not change the crown prince easily. Li Er also has the limitations of genius. He cannot see the difficulties of ordinary people. He thinks that the problems faced by the prince are small problems and can be easily solved.

The protagonist is like a naughty child, shouting that I have this but you don't, I'm awesome (smug face)

The protagonist is so stupid that he can experience it himself and believe in the various conspiracies about Li Er on the forum. He also wanted to get rid of Li Chengqian, so he looked up what Chengqian meant in the dictionary before speaking. He really didn't want to see Li Chengqian, and he would have been done with all those bad things he did. The simplest point is that Li Chengqian wore Turkic clothes and played simulation games at home. This alone was enough to ruin him more than a dozen times. What is this equivalent to now? The heir to a country wears a kimono at home and lets people around him talk in Japanese, fully becoming a Japanese person. Even if Li Shimin doesn't get rid of him, he is already very kind to him.

If you don't develop the Tang Dynasty well if you have a double-traveling, you will only be able to fight in the palace all day long. What's the point? Female channel?

If you don't want to have a gun if you don't want to have a double-crossing demon, you should still be doing it in China, written by the AI ​​of a traitor.

The protagonist brought out so many things, but Li Shimin didn't know?

If you sell ancient resources in modern times, a few hundred million a year should be enough. If you sell modern things in ancient times, you can make a lot of money. And being able to connect directly to modern times means you can have an unlimited supply point. You hardly have to worry about logistics when leading an army. Moreover, some modern medicines and the like were almost miraculous in ancient times, so your men hardly have to worry about death. You can buy seamless steel pipes to make rifled guns, you can make breech-loading cannons, and you can make anything for civilian use. Find a place to develop for a period of time, and when you develop, go abroad to buy some weapons. It is really impossible to cooperate with the country. As long as you can create a small industrial cycle. With an established gun and artillery combination, coupled with a small number of machine guns and cannons, even Liu Xiu, Liu Bang, Xiang Yu, Li Shimin, etc., I would like to have a try. After all, even if they hit you with a meteorite, you can still go back to modern times and start over. After all, I can't think of how you can lose with your modern development power, unless you die of stupidity.

This book should go to a female channel, it would be a shame to hang it here in such a big way.

What era was that then? Why did you buy sunken rice during the famine years? That's why you can go directly to buy feed and stuff. Although modern people cannot eat it, in ancient times, it was a life-saving food, and it was cheap!
