Yingyi came up holding a ceramic jar.

The mouth of the pottery jar is sealed with plaster, which can keep the inside of the jar dry.

In fact, when Su Yin heard that the things were placed in the well, she was still a little worried that they would be corroded and damaged by water, but it was obvious that Nanny Hongxiu had also thought of this and hid the things very well.

Remove the sealed plaster and pour the contents out of the jar. Perhaps the contents are too big and the bottle mouth is too small, so it gets stuck.

The three men decided to go all out and broke the pottery jar. An object wrapped in three layers of oil paper appeared. After removing the oil paper, they found a rosewood box inside. The entire rosewood box was well preserved and showed no signs of decay.

After getting the things, Su Yin and her brother said goodbye to Nanny Hong Xiu, took the things and left the palace. The follow-up matters were directly handed over to the Dark Pavilion to clean up.

The brother and sister returned to Su's house with their things.

In the study, the brother and sister sat on the couch, with today's harvest placed on the coffee table.

There was a small lock on the rosewood box, but the two of them didn't have a key, and Nanny Hongxiu didn't give them a key either.

It is quite simple to open the rosewood box. As former top killers, lock picking is just a part of their learning.

A killer who can't open a lock is definitely not a qualified secret chamber killer.

"Brother, I leave it to you."

Su Yin handed the rosewood box to her brother consciously, "Those who are capable should do more work. Thank you for your hard work, locksmith."

Su Xinguang; "(????)..."

It’s better not to have this sister!

Su Xinguang did not hesitate and got it done easily in no time.

The rosewood box was opened, and the two looked at the contents of the box together. There was a thick stack of letters inside, and the handwriting on the top letter was completely different from the letters at the bottom.

Pick up the letter on the top layer and judging from the narration tone, it should be from Aunt Lianqiao.

[Your Highness the Crown Prince…]

The content of the letter was very long. In it, she was apologizing for taking him away that year. At the same time, the letter mentioned that Concubine Li and her maternal family, Duke Rong, colluded with foreign tribes and planned to use someone else as a substitute.

If the baby was a boy, everything would be fine. If not, a baby boy that had been prepared outside the palace would be brought in to replace the royal bloodline.

Unfortunately, Concubine Li gave birth to a girl. She should have been a princess, but was replaced by a boy of unknown origin.

The letter also mentioned that Duke Rong contacted people from the Darong Kingdom, disguised themselves as remnants of the previous dynasty, and killed the eldest prince.

She was grateful to the imperial concubine for saving her life, and took the eldest prince away on her own initiative.

Below are the letters she collected about the conspiracy between Concubine Li and Duke Rong. These letters should have been burned, but she secretly replaced them several times.

Seeing this, Su Yin actually understood that Lian Qiao already knew his fate at that time.

Since Concubine Li revealed the secret to her without any scruples and asked her to burn the letters, it was obvious that she had long been planning to silence her.

A dead person naturally doesn't have to worry about so many things.

Unfortunately, Concubine Li underestimated the ants she looked down upon.

These letters are all encrypted, and Lian Qiao also mentioned the decryption method in the letter.

Su Yin and Su Xinguang took out the letters that were buried underneath. They each took a part and read all the letters according to the decryption method provided by Lian Qiao. After reading them, they had only one feeling.

How crazy!

Whether it is Concubine Li or Duke Rong, they really have evil ambitions.

"Sister, with this piece of evidence, we can bring all those royalists to our side."

Su Yin shook her head. "That's not enough! We have to let them know that we have the ability to take that position, and then those royalists will follow us. Even if they know that Emperor Rongxian is not of royal blood, they can still turn to the seemingly more powerful Prince Qin and Prince Jing."

When doing anything, you have to consider and look at things from the perspective of the other party's interests. If you take things for granted, you will eventually fall flat on your face.

"The first step we need to take now is to win over Duke Su to our side. With Duke Su's support, it will be much easier to convince other royalists."

Su Xinguang pondered for a moment and said, "I will tell my grandmother and the others about what happened here, and also inform my brother."

"good."

Hot Spring City Qingxi Mountain

Through the secret cabinet, Su Yin and their letters were delivered to Su Xiaozhong as quickly as possible, and Su Yin copied a letter written by Aunt Lian Qiao, which also contained an original secret letter.

Su Yin didn't give much, and the rest was in his own hands.

That original secret letter was for my father in case of emergency.

After Su Xiaozhong finished reading the contents of the letter, he picked up the other two letters. After reading all the contents on them, he let out a long sigh of relief.

He understood what his daughter meant.

He found Queen Chen, told her what had happened, and handed the three letters to her.

After Queen Chen finished reading Su Yin's story and Lian Qiao's letter, she inexplicably thought of a sentence.

Good deeds will be rewarded!

I helped her out that day, and she has always kept this favor in her heart.

Without the kindness that day, perhaps there would be nothing we have now.

"Xiaozhong, it's spring now, why not go to the Northwest Army for a walk."

"Okay, son, I'll get ready to go."

"Mother will go too." Queen Chen said.

"Mom, you..."

"With me here, Duke Su will not make things too difficult for you for my sake."

Su Xiaozhong naturally knew that his mother's lethality and persuasiveness must be greater than his own.

After making the decision, Su Xiaozhong took Empress Chen, his wife, and dozens of guards to the northwest. Of course, there were also many shadow guards protecting them in secret.

Northwest Army

Master Wan San escorted the last batch of food, fodder, cotton clothes and other items to the Northwest Army camp. When the soldiers in charge of guarding saw that it was Master Wan San, they conducted a routine check as per usual and immediately let him go.

Master Wan San bowed to the guards and entered the military camp with food and fodder.

After they entered the military camp, the guards couldn't help but sigh.

"I don't know who that girl named Song Yin is. She actually sent us so much food."

"Although I don't know who she is, she really cares about us generals."

"That's right. If she hadn't sent us so much food continuously, we would have lived frugally in the winters of previous years. Now we can have enough to eat every day."

As the two were chatting, the soldiers who were changing shifts came over to take their places. When the soldiers suddenly saw the Lei Feng hats and gloves they were wearing, their eyes widened.

"Where are you guys from?"

The soldier wearing the Lei Feng cap said with a smile: "Hey, I just received it from Master Wan San. You better hurry up, if you are late, you will have to wait for the next batch."
