Xuanzhong Gate is the first line of defense to enter the inner court.

After passing through Xuanzhong Gate, there is Xuanwu Gate.

In front of the door is an open square, which together with two doors form a urn city in the back courtyard of the palace.

Once you attack Xuanwu Gate, there will be basically no danger to defend the backyard.

When Li Er killed his brother and brother here, he forced me to palace him, and eventually made the Emperor of Eternal Eternity and made Xuanwu Gate the most famous palace gate in history.

In fact, in addition to Li Er's palace transformation this time, there were two palace transformations in the Tang Dynasty that also occurred at Xuanwu Gate.

One is the coup of Prince Li Chongjun in the first year of Jinglong in Emperor Zhongzong of Tang Dynasty (707 AD).

After the reinstatement of Zhongzong Li Xian, he was weak and incompetent, while the Empress Wei was strong. She colluded with Wu Sansi and took charge of the government affairs.

Crown Prince Li Chongjun, together with Zuo Yulin General Li Duozuo and others, pretended to be ordered and led Zuo Yulin and more than 300 thousand cavalrymen to rush into the mansion of Wu Sansi and Wu Chongxun, killed Sansi and Chongxun, and then sent troops to surround the palace, asking Empress Wei and Princess Anle.

Empress Wei heard about the change and took Zhongzong to the Xuanwu Gate Tower hostage, turning the situation around, which was known in history as the "Empress Wei Rebellion".

Of course, this palace change ended in failure, and the great-grandson did not have the ability of his great-grandfather.

The second time was the coup of Li Longji in the fourth year of Jinglong (710 AD) of Emperor Zhongzong of Tang Dynasty.

In June of that year, Empress Wei and Princess Anle and others conspired to poison Zhongzong Li Xian to death and make King Wen Li Chongmao the emperor.

Empress Wei wanted to follow Wu Zetian and become emperor, so she arranged for the Wei family to be the key departments in the capital, gathered the party members, and prepared to depose Chongmao and become independent, but she was afraid of the prime minister, so the Grand Marshal Li Dan opposed it, so she wanted to find an opportunity to kill him.

Li Longji, the son of the Prime Minister and the King of Linzi, received a secret report, that he would join forces with Princess Taiping and others to take the initiative and rush into the Yulin Guards, kill Wei Yu and Wei Bo, who were sent by Empress Wei to command the guards, occupy Xuanwu Gate, and then lead troops into the palace, kill Empress Wei and Princess Anle.

The Prime Minister Li Dan and Longji and his son took control of military and political power. Later, they intimidated the Shao Emperor Chongmao to give way, and the Prime Minister ascended the throne, which was the Emperor Ruizong.

This time, Li Er's great-grandson became awesome. The palace transformation was successful and eventually achieved the Kaiyuan prosperous era that has been passed down through the ages.

However, later emperors obviously learned from the lessons of the past and continuously transformed and upgraded the defense system of Xuanwu Gate, and its rigor was far beyond people's imagination.

The Xuanwu Gate in front of Li Xu was obviously not ordinary. Although there was only one door, there was a tall and sturdy city tower on the door, and there were long corridors on both sides.

There are dense archery mouths on the corridor, and there is even a tall tower every few dozen steps.

Although I couldn't see anything upstairs, Li Xu could probably think that he must have deployed heavy weapons such as bed crossbows with extremely long range and extremely lethality.

Li Xu even saw the shadows of the corridor through the archery mouths, which were the Longxiong Guards guards guarding them.

Although the Longxiang Guard and the Jinwu Guard are both Imperial Guards, they are directly under the royal family and are responsible for guarding the palace, so they are also called the Northern Ya Imperial Guards.

The other eight guards were stationed in various directions of Chang'an City and were dispatched by the cabinet, so they were also called the Southern Ya Imperial Army.

Mu Di helped Yu Yu and Li Xu get off the imperial carriage, and when he got here he had to walk into the palace.

While Li Xu walked forward, he looked at the surrounding environment seemingly unintentionally, and the small map of the system in his mind also popped up.

The outline of Xuanwu Gate is displayed on the map, and the dense gray dots nearby are also displayed, both still and regularly moving.

The soldiers standing still are the soldiers standing guard, and the soldiers moving are naturally the soldiers patrolling.

In addition to the many soldiers guarding the bridge above Xuanwu Gate, there are many in the city wall below, and obviously there are also hidden soldiers caves below.

Li Xu even found some slowly moving small dots below, which were obviously the tunnels of secret hidden soldiers near Xuanwu Gate, and it was probably used as surprises.

The strict defense of Xuanwu Gate is indeed a little beyond Li Xu's expectations, but then he thought about it but felt that it was not very meaningful.

If the enemy really attacks Xuanwu Gate, it means that the situation is already hopeless. No matter how strict the defense of a palace gate is, it will be useless. After all, no matter how strong the defense is, it will be accomplished by people.

If all people's hearts are dispersed, nothing will be useful.

Secondly, if I really want to lead my troops to attack the palace one day, I will definitely attack with artillery.

In front of artillery, how long can this ancient city wall with brick and stone structure last?

In my previous life, why did the cities in the future demolish the city walls one after another? First, it was because it restricted the development of the city, and second, it was because the city walls had lost their original defensive significance, and they were only left as historical relics for people to view.

In front of artillery, even the strongest city wall is meaningless.

Not to mention missile nuclear bombs, even ground-boring bombs during World War II could be destroyed instantly by steel and concrete, let alone the ancient city walls with brick and stone bonded with glutinous rice water.

Nothing is.

Li Xu was thinking about these things, but this thoughtful expression fell on Mu Di beside him, which made the white-bearded eunuch with a naked chin and couldn't help but feel suspicious. He looked at Li Xu quietly, not knowing what he was thinking.

Li Xu is now opening the system minimap, and his emotional changes to the people around him are particularly obvious, not to mention that Mu Di is following him.

Looking at the little place representing Mu Di, who changed from a slightly yellow to a little red color, Li Xu came to his senses, looked at Mu Di with a smile, and said, "Eunuch Mu, do you have any flowers on my face?"

Mu Di was so madly that he saw it, and he burst into tears and said with a hurried smile on his face: "The Admiral is joking, it's because our family is abrupt."

Li Xu probably understood his thoughts when he looked at the old eunuch. The position of this empress dowager or the confidant eunuch around the emperor must be consistent with that of the master.

Without a master, they are nothing.

So like their masters, they are naturally alert and suspicious of generals like Li Xu who hold military power.

Although Li Xu is now the most important rookie of the Song family, the interests of Song family are not exactly the same as those of the empress dowager and the emperor. Mu Di naturally understands this and naturally keeps a vigilance towards Li Xu.

Especially in sensitive places like Xuanwu Gate.

He thought he was very self-righteous and hid, but he didn't expect that Li Xu was a cheater.

Li Xu smiled and said nothing.

Mu Di is just a small person, and even a small person is not considered a small person.

If Li Xu was an ambitious man who wanted to cling to the Song family and climb up the power of the empress dowager, Mu Di would naturally have to curry favor with him.

It’s a pity that he is not. He relies on his strength to win the world. Whether Mu Di dies in the future depends on whether he is happy or not.

The group did not speak anymore and successfully passed Xuanwu Gate.

A palace servant had been waiting behind Xuanwu Gate, saying that the Empress Dowager and the Emperor had already held a banquet in the water pavilion on Taiye Pool.

Mu Di took Li Xu and Yu Yu all the way through the corridor and walked forward across the bridge. After about half an hour, he finally arrived at Taiye Pool.
