After a few days of marching, the Tang Dynasty army took its place and completely cut off Luoyang's contact with the outside world.

Li Shimin set up camp at the foot of the Beibi Mountain. In order to deter the enemy, Li Shimin ordered all the barracks of the whole army to be made of white canvas.

I saw that the white tents were continuous, and there was no edge in sight, as if a white belt was wrapped around the cyan mountain.

The defenders at the north gate of Luoyang City looked up and couldn't help but gasp.

The Tang army was so powerful that even the mountain wind blew and sent bursts of killing intent, shocking the enemy's heart.

Li Shimin is familiar with military books, and the soldiers who surrender without a fight are really the best choice. He used this suspicious tactic to attack his heart. As long as the enemy is terrified by this, the enemy's morale and combat power will be greatly reduced.

Li Shimin was not in a hurry to attack the city, he just immediately went halfway up the mountain all day long to observe the situation in Luoyang City.

Shaanxi East Road Xingtai, built with the Son of Heaven flag, can preside over the surrender on behalf of the Son of Heaven.

A few days later, the lowering tables of the Central Plains prefectures and counties came like snowflakes, and Li Shimin replied one by one with the order of the Shaanxi East Road.

Soon, all over the Central Plains, in addition to the city guarded by Wang Shichong's relatives and henchmen, the banners of the Tang Dynasty were planted, and Luoyang had completely become a lonely city!

Yan Lide led 5,000 soldiers and horses into Bishan to cut wood and make siege equipment, and after more than 20 days of rushing to make them, all of them were completed.

On August 1, Li Shimin officially issued a general attack order against Luoyang City! Huge stone throwers continued to throw boulders into the city, and the Tang army set up ladders and climbed the city wall like ants.

When the vanguard of the Tang Army was about to climb the city wall, a row of huge iron barrels suddenly appeared on the city wall, boiling hot oil poured down, and rows of point rockets followed closely behind......

Suddenly, tongues of fire burst out, and with a painful howl, the corpses of the Tang army fell to death at the foot of the city wall.

Seeing the situation, Li Shimin urgently ordered the Tang army to stop the siege. After counting, nearly 2,000 people were lost in one morning.

Li Shimin knew that something was wrong, it seemed that Wang Shichong had hidden his strength, and it was obviously not advisable to attack the city on such a large scale.

At this time, he gradually understood why Li Mi had millions of troops, but he never captured Luoyang City.

Since the construction of Luoyang City in the first year of the Great Cause, it has been besieged by hundreds of thousands of troops in turn several times, and it has always been intact.

Luoyang Wangcheng is said to be the strongest city in the world, an insurmountable city.

……

Seventeen years ago, Yang Guang had just ascended the throne. After riding a horse to inspect the terrain of the Beibi Mountains, he was fascinated by the mountains and rivers here.

After some deliberation, he decided to build a large-scale royal city on this site.

Yang Guang was an ambitious emperor, and he demanded that the city be bold and show the supremacy of imperial power.

Under the guidance of this concept, the famous architect Yu Wenkai did his best to build Luoyang City to be extremely grand.

The city stretches for more than 200 miles, and the city wall is about more than two zhang thick. The foundation stones of the city walls are all made of the strongest granite, and each gate is made of 1,000-year-old cedar outer cast copper. At the four corners of the city wall, there are tall watchtowers, and there are arrow towers every other stone's throw away. The city is densely defended, and there is no defensive blind spot at all. In addition, there is a moat more than two feet wide around the city.

In the city, the city is connected and has complete functions. Luoshui runs through the city and flows outside the city to connect with the canal. The canal is directly connected to the Yellow River, and is close to the north-south Grand Canal, so the water transportation is very convenient.

In the imperial city, there are carved beams and painted buildings everywhere, and they are splendid, and they are extremely luxurious. Pavilions and pavilions, magnificent and majestic, showing the grand spirit. It is only used to hold the Qianyang Hall of the National Ceremony, the main body is more than 60 meters high, nearly a mile wide, and can accommodate nearly 10,000 people to gather together at a time.

After the imperial city, a forbidden garden was built for the emperor to rest and entertain. It's a huge playground filled with exotic trees, BMW eagle dogs, and objects from all over the world. Yang Guang also ordered his favored ministers to collect the beauties of the world and let them live in them for their own enjoyment.

In the underground of the whole city, there is also a quiet underground palace built for storing food and ordnance. In the dungeon, there are many secret doors leading to the outside of the city through tunnels. These secret doors are known only to a very small number of people.

The construction of Luoyang City was completed in only nine months.

It is said that half of the adult men in the world participated in the construction of Luoyang City at that time, which shows the large number of people employed.

After the construction of Luoyang City, Yang Guang often lived here. Every year during the Lantern Festival, he has to feast his ministers here, invite them to visit the fireworks show together, guess the lantern riddles, and sing to each other.

On the night of the Lantern Festival, the skyrocketing fireworks illuminate the whole city as if it were day, and it will not stop all night.

When the Sui Dynasty was strong, there were as many as 100,000 foreigners who came to Luoyang City to see the fireworks.

……

More than ten years have passed, the prosperity has dispersed, and the troubled times are coming.

Luoyang City has not lost its majesty and solemnity, and this impregnable huge royal city seems to have become a refuge for Wang Shichong.
