It was especially dark in the suburbs of Chang 'an at night.
Although the Great Tang was now prosperous…
However, it was still the same as the world 1,500 years later.
There was a difference between heaven and earth.
Chang 'an City didn't have street lamps that lit up overnight!
Not to mention that at night, the outskirts of Chang 'an, where there were no ghosts, were pitch black.
However, after Zhang Yan and the 3,000 Raven Killer Army charged out of Chang 'an Fortress, the two of them were killed.
However, he was not troubled by the darkness.
He didn't even light a lantern.
It was not only because the weather was fine tonight, but also because the moon was bright and the stars were sparse.
It was also because Chang 'an Fortress behind him was the best candle at this moment!
More than half of Chang 'an was set ablaze by the raging flames.
The flames were even higher than the ten-meter-high wall.
It brought about endless heat and light.
It lit up the night sky like it was daytime.
It also illuminated the vast suburbs of Chang 'an!
Zhang Yan and the 3,000 Raven Killer Army.
They were all battle-hardened existences. Marching through the night and Dai Yue's surprise attack was a common occurrence.
And now, it was such a perfect time and place.
Naturally, it was like adding wings to a tiger!
In the time it took to brew a cup of tea, he had already rushed out of Chang 'an City.
Suddenly, just as everyone rode past a dense forest.
Zhang Yan, who was the leader, suddenly narrowed his eyes! He suddenly pulled the reins in his hand.
"All troops, halt!"
Following Zhang Yan's shout, the 3,000 Raven Killer Army soldiers reined in their horses.
Then, without Zhang Yan's instructions!
The swords and sabers were unsheathed in an orderly manner. In the blink of an eye, they had formed a battle formation.
He looked around vigilantly.
They were afraid that there was an ambush!
As for Zhang Yan, although he was frowning, he didn't look too nervous.
He looked at a certain spot in the forest.
He suddenly waved his hand.
He said a secret code!
"Dragon swimming into the sea! Come out!"
Swoosh! Swoosh! Swoosh!
As soon as Zhang Yan finished speaking, a rustling sound was heard.
In the dark forest, a pitch-black curtain fell silently!
Immediately after, a group of about a thousand people silently appeared.
They were wearing the same armor as the 3,000 soldiers of the Raven Killer Army, but the color was different.
The armor of the 3,000 Raven Killer Army was an inconspicuous dark green color.
However, the armor of the soldiers in front of him was a faint blue color!
In the dark night, it was exceptionally hidden.
Everyone knew that Zhang Yan had 3,000 Raven Kill Army soldiers under him. One of them could fight against a hundred, and no one could match them on the battlefield.
Little did they know that Zhang Yan actually had four private armies under him.
Other than the three thousand Raven Killer Army that everyone knew about.
There were also three armies hidden in various parts of the Great Tang.
Although each army only had 3,000 people, their roles and strengths were different, and they were all exceptionally powerful.
Very few outsiders knew about it, let alone Li Er and the ministers in the court.
The 1,000 men in front of him were part of the 3,000 Long You Army.
Dragon swimming into the sea was originally a retreat route that Zhang Yan had left for himself just in case.
However, he didn't expect that his precautions would actually be useful today!
"General Long You, Zhang Shiba greets you!”
Soon, a young man in blue took the lead and rushed in front of Zhang Yan's horse.
He smiled and cupped his hands on one knee.
Zhang Yan had set up four armies, each with a commander in charge.
His name was General! It was the intention of the leader of an army.
They only listened to Zhang Yan's orders.
The general of the 3,000 Raven Killer Army was Old Jiang, who was dressed like a butler.
The commander of the 3,000-strong Long You Army was this young man in blue.
He looked about the same age as Zhang Yan.
When she smiled, she looked especially radiant.
However, although this young man looked sunny and handsome, in reality, he was a young man.
Among the four Great Commanders, this guy was the best and most vicious!
Even the leader of the four generals, Old Jiang, who had killed countless people on the battlefield.
He also often called this young man "Little Madman"!
"Get up!"
The appearance of Zhang Shiba and Long Youjun…
Zhang Yan naturally wouldn't find it strange.
After all, unlike the Raven Killer Army, which was only responsible for fighting on the battlefield, the Dragon Roaming Army was more focused on surprise attacks.
He also had Zhang Yan's biggest trump card, the Firearm Research Lab!
Yes, this Firearms Research Lab was a place that Zhang Yan had specially opened up to study the firearms of the future, which far surpassed the intelligence of the Great Tang.
Whether it was the gasoline that had burned the entire Great Wall today, it would be impossible for even the gods to save it.
It was the gunpowder that blew open a gate on the city wall of Chang 'an that no one could break.
It was all developed and improved by the Firearms Research Lab under Zhang Yan's guidance.
What was worth mentioning was…
The explosion that blew apart the city wall of Chang 'an and caught the people of the Great Wall unprepared.
It was Zhang Shiba's method!
The huge firework that Zhang Yan had ignited in the night sky of Chang 'an.
It was the signal to inform everyone to take action.
Otherwise, even if Zhang Yan had extraordinary means to break through Chang 'an Fortress's impregnable defense, he would not be able to do so.
It would probably take quite a bit of effort.
Not to mention now, he had turned Chang 'an upside down without spending a single soldier.
He retreated unscathed!
