"Our emperor conferred the title of the eldest princess a few months ago. The emperor said that she was his savior when he was young. I think none of you readers believe this, right? Even His Royal Highness the Crown Prince doesn't believe it.

Alas, that’s not the case. Our eldest princess is the real eldest princess.

A few days ago, news came back from the front line that the Jinjiang City of the Wei Dynasty that I, Canglan, had captured was taken back by the Wei Dynasty.

My Canglan soldiers were so brave, but they failed to hold on.

Why? Because the Great Wei created a powerful weapon beyond everyone's imagination. With this weapon, the Great Wei defeated the Canglan soldiers and forced them to retreat to Luo'an City.

This incident made the emperor furious, so he revealed the identity of our eldest princess.

The eldest princess is our emperor's biological sister. More than forty years ago, she faked her death and was arranged by the late emperor to go to Wei. She became a concubine in the palace of Prince Rong of Wei. She lay dormant all her life and sacrificed her whole life for me, Canglan.

Yichu provided Canglan with news about the Great Wei, and finally stole the iron box from the Great Wei and brought it back to Canglan.

But the problem is that it is said that the iron box has been opened by the Wei Dynasty a long time ago, causing the Princess's years of hard work to go down the drain.

But they have indeed made great sacrifices for me, Canglan, and are the bravest and greatest princesses of my Canglan.

…”

The storyteller continued with great voice and emotion.

When Prince Jing and his two companions heard this, they knew that this storyteller was most likely bribed by Shangguan Hongzhe.

Now that Dawei has opened the iron box, their situation with Canglan is worrying.

They developed a sense of crisis and wanted to gain support from public opinion so that Emperor Canglan would not blame them for this matter.

Otherwise, Emperor Canglan would not just recognize her as his adopted sister, but would directly acknowledge her identity.

Without going to confirm it, Prince Jing became more certain after listening to the storyteller's narration.

At this moment, a luxurious carriage passed by the teahouse.

Prince Jing and his two companions happened to be sitting by the window, looking down.

Look carefully, the third old lady of Prince Rong's mansion is sitting in the fragrant carriage with light gauze dancing in the air.

Shangguan Hongzhe was riding a horse guarding the carriage. Although he was wearing a half-mask, Prince Jingjing recognized him from his figure and the lower half of his face.

"Look, the princess and Prince Zhe are passing by downstairs." A guest also looked out the window and happened to see it. He couldn't control his surprise and shouted.

This attracted Shangguan Hongzhe's attention upstairs.

Prince Jing immediately retracted his head.

The group had achieved their purpose of going out today, and after drinking two cups of tea, they returned to their rented place.

"Father, what should we do next?" Cao Jinyu asked.

"The purpose of our coming to Canglan is to bring the iron box back. Then find out where the iron box is. Once you get it, we will return home immediately."

"But it's easier said than done." Cao Jinyu knew that this was not an easy matter.

"Well, there's no rush. Let's plan slowly."

In the following days, Prince Jing arranged for people to find out the situation in the Canglan Palace.

With Yun Ling's help, they actually found a way to sneak into the palace.

That is, the little eunuch who goes in and out of the palace every day to pour night incense is a breakthrough.

There are ten night incense collectors in Canglan Palace, who push out from the west corner gate before dawn every day. There is a place in the city that specializes in collecting night incense, and then transports it out of the city to sell to farmers as fertilizer.

Two of them would carry a car and pour it out.

They took advantage of the opportunity.

After observing for a few days, I found that these people were not together. Whoever was faster would come out first.

If you fall, go back. Check the correct cards when you go in.

Prince Jing and his men sneaked into the palace in several groups.

They took advantage of the fact that there was no one around a group of people pouring night incense, knocked down the two men, dragged them away, and had their own people disguise themselves as two eunuchs in advance, put on their clothes, took their belongings, and sneaked into the palace.

First, sneak in a group, and after getting familiar with the inside, take advantage of the time when they come out to pour out the night incense, then hide people under the carriage one by one and bring them in.

In this way, after about twenty days, Prince Jing and a dozen of his men sneaked into the Canglan Palace.

The two who pretended to be night incense lovers were on the surface.

Build relationships with the palace maids and inquire about the news in each palace.

The dozen or so people who hid hid in the cold palace.

Emperor Canglan is already old, and there are few concubines who were banished to the cold palace and are still alive, so there is basically no one living here.

At night, they would secretly inquire about the situation in the palace.

Get rid of a eunuch when you get the right opportunity, and you will easily become that person in the future.

And during the time they were in the palace, Shangguan Ziqi captured another city on the front line.

Now two cities have been recovered.

On the other side of Rongyun City, General Chen had already driven the attacking enemy back to Canglan.

The eldest prince immediately launched an attack on Cangjiang City of Canglan, where there were 30,000 Canglan defenders.

The eldest prince had few bombs, only ten. He fired three of them and frightened the enemy so much that they defended the city and dared not come out.

Bomb production couldn't keep up with demand, so they had to slow down.

at the same time.

The army led by Prince Liu of Southern Shu also reached the border with Canglan.

When Emperor Canglan received the news, he was so angry that he cursed his own sister in the imperial study.

But he also knew that his sister had done so much for him, and he couldn't blame her entirely for her incompetence.

The Imperial City Guard had 300,000 troops. When he learned that Southern Shu had sent out troops, he sent out 50,000 advance troops.

He also issued orders to garrisons in various places to dispatch troops to provide support.

There are nearly 800,000 soldiers in the entire Canglan, and it is impossible for all of them to be deployed to the front line. Only the Imperial City Guards are agile.

Now they have all been sent out.

Simply put, we were attacked from both sides.

He now had no good solution and could only rely on the soldiers on the front line.

He couldn't wait to think about the idea proposed by the prince.

But he felt that the idea was too toxic, and if it went wrong, it would affect him, so he wanted to wait a little longer.

These days, Emperor Canglan never entered the harem again, and he rested in the imperial study all the time.

That night, he took out the iron box again and wanted to give it a try.

Da Wei was able to open it, maybe he was lucky enough to open it.

He estimated that the formula of the bomb was still in the iron box.

Because the iron box is the safest place, the most Da Wei could do is take it out and copy it.

The iron box is safe no matter who holds it.

As long as you can't open it, you can't get the recipe.

He fiddled with it countless times, but it didn't budge.

"Eunuch Mo, you come and try it too." Emperor Canglan became impatient and called the chief steward who served his concubine to come and try.

"Your Majesty, how can a servant be qualified to touch such an expensive thing?" The old eunuch did not dare to touch it.

What if he really guessed it right and it opened? Would he still have a chance to survive?

The emperor would definitely get the password, and then give him a cup of poisoned wine to make him shut up forever.

He doesn't want to die yet.

"Just try it if I tell you to, and stop thinking about unnecessary things." Emperor Canglan shouted coldly.

The chief steward had no choice but to step forward tremblingly.

"Your Majesty, that old servant has gone beyond the rules."

"Okay, if you can really open it, I will remember your great achievement."

"Thank you, Your Majesty."

The chief steward dialed the number with trembling hands.

But his forehead was covered with sweat and there was no movement at all.

He was about to plead guilty.

Suddenly, there was a loud "boom" sound, which frightened Emperor Canglan and the old eunuch so much that they fell to the ground.
