Just after Tuyuhun, the envoy of Gaochang, was driven away as sad as his father, Li Shimin issued an order to reprimand Gao Jianwu, and finally read many respects before him, before expressing forgiveness, these frightened Tubo and other countries have increased the gifts of worship, and they are worried about the revenge of the Tang Dynasty.

Fortunately, Li Shimin generously forgave them and said that next time, he must destroy his country.

This time, many envoys worshipped, which made Li Shimin feel very good, and let people take them to visit the newly renovated Chang'an City scenic spots.

The prosperous new Chang'an, so that the envoys were dumbfounded, unable to move, although it was said that they had seen the flowers, but under the introduction of the guide, they understood their shallowness.

The prosperity of people coming and going, are visible, the hidden internal facilities, is what they dare not imagine, every household water, is actually a copper pipe connected to the porcelain pipe, with a twist of the hand can be out of the water.

Ondol, black honeycomb carbon that burns without wood, and countless transparent glasses are used to build houses, in their tribes, countries, and every family that regards them as treasures.

This made them feel inferior after being shocked, and envious after inferiority, many small patriarchs have already decided to take their clansmen to join the Tang Dynasty after they go back, and at least they have to bring their families to live in Chang'an.

Many people have secretly inquired about what conditions are needed to live in Chang'an.

After discussing with Feng Daiwen and others, Li Shimin issued an order to welcome people from other races to settle in Chang'an.

The alien Fanbang who can come to Chang'an to settle down, of course, are rich people, they come to Chang'an, it will inevitably drive consumption, this is a good thing, naturally the more the better, you must know that in the former Han Dynasty, many times moved to various rich households, gathered in Guanzhong, this is to strengthen the central government, weak places.

Although there is no need to deliberately relocate the rich now, it is always a good thing to have more rich people of different races, of course, after they have no money, whether they can survive in Chang'an or not, it doesn't matter to the imperial court.

…………

The basic renovation of Chang'an City has been completed, and the palace complex of Longshou has also accelerated its speed, no wonder Li Shimin is unhappy, the palace group has only built the foundation, but the villas under the halfway mountain have been built, and it is expected that the final decoration will be carried out after the year.

Chang'an has too many people, Feng Daiwen and Li Shimin and others after discussion, decided to build a new city at the foot of the mountain, and build a 15-kilometer railway, to connect the two cities, the new city will become a leisure, entertainment city, the new city is a city without walls, the first to build a huge amusement park, including a zoo, a botanical garden, and a children's amusement park.

Because of the advent of the steam engine and the role of steel alloys, many large-scale amusement rides can also be made, but they are not as exaggerated as later generations, belonging to the weakened version of the pirate ship, the slow running roller coaster, the merry-go-round and so on.

In Feng Daiwen's planning, the new city is a place for everyone to have fun and relax, with the affluence of people's lives, more pursuit will become amusement, which is inevitable, it is better than buying drunk if you have money, and Pingkangfang spends all day drinking.

Before the New Year arrived, Feng Daiwen was pulled by Li Chunfeng to the scientific research institute for retreat, and it turned out that Li Chunfeng, who came back from western Liaoning, never forgot the steam car proposed by Feng Daiwen.

After coming back, he took more than a dozen craftsmen to make one for more than a month, but there were various problems, and now that Feng Daiwen is back, of course he will be found for guidance.

It is said to be a car, but it is a behemoth, with a three-zhang long body, an all-steel convertible, half of the steam engine at the front, and twelve wide iron wheels below, which can be driven but slower than walking, and the cement road needs to be thickened, otherwise it will be deeply trapped.

After Feng Daiwen read it, he also admired their imagination, so he put forward a few suggestions.

Rear drive is adopted, the steam engine is installed in the back, the wheels are geared, and the bottom plate is tracked, so that there is not so much requirement for the road surface, anyway, now it is deserted everywhere, there are not so dense houses and roads.

And the first one must belong to Li Shimin, otherwise it will definitely make him uncomfortable, Li Shimin is uncomfortable, everyone should not think about being comfortable.

Since it is a royal item, it is natural to have a royal bearing, the shape is designed as a dragon head, and the steel machine does not need to be changed, it is already very powerful, and the top is open-topped, which is for his inspection.

The high-manganese steel tracks made of stamping are all riveted to ensure the hardness, at least not at least not yet to destroy its existence.

There is not much problem with the design of the machine itself, although it is in the form of armor, it is only an appearance, the inside is a steam engine, a console, and then there is the seat of Li Shimin and his wife, and a few guards can stand on both sides, and the density is a little larger, and it can squeeze down twenty people.

The piston steam engine drives the transmission shaft, uses the size of the gear to change the speed, the steam size can also change the speed, and the brake is the steel plate on the side of the tire, which uses friction to slow down and reduce the amount of steam at the same time, double insurance.

A large number of steel plates are used below to absorb the shock, at least to make this big guy of more than 3,000 catties (five tons) not so hard to run.

"It's done! It's done! Ha ha! ”

"Wow! Ha ha! ”

The sixth year of Zhenguan, the fourteenth day of the first month!

In a frenzied cheer, the first tracked, steam locomotive officially ran successfully, advancing on the ground at the speed of a normal person, the sound of the steam engine, coupled with the roar of the car forward, made the nearby ground shake.

This is the result of more than 200 craftsmen of the scientific research institute working day and night, in order to pursue the progress, the body and the body are made separately, and then assembled, the interior decoration is also very simple, only the seat of Li Shimin and his wife is made of cotton cushions, to ensure comfort.

The huge white bear skin offered by the drive is laid on it, which is both warm and powerful.

The car drove in the scientific research institute for half an hour, and there was no problem, Feng Daiwen put his mind at ease, while asking Li Chunfeng to lead people to overhaul, and rode into the palace by himself, to invite Li Shimin and his wife to come to adapt, so as to facilitate the Lantern Festival the next day to ride and inspect.

Suzaku Street is spacious, thick roads, to ensure that vehicles can go back and forth smoothly, Chang'an outside the city has also leveled out a twenty-mile road around the city, when Li Shimin will go around the city for a week, inspect Chang'an.

Feng Daiwen invited Li Shimin and his wife, as well as Li Chengqian's brothers who rushed to hear the news, but no one else knew.

"The queen mother has a short rest, father, please get in the car!" Feng Daiwen helped Li Shimin into the car, and stood on his side himself, and four guards followed cautiously.

Li Shimin also believed that Feng Daiwen would not harm himself, so he got into the car with confidence, and after looking at it, he looked around curiously.
