The daughter of a general is reborn to save the whole family of the marquis

Chu Heyi turned the letter over and over again, but still couldn't find any sign of a signature, and she had never seen such handwriting among all the people she knew.

She asked Baihua: "Where did you get this letter?"

Baihua said: "The messenger said that the Fourth Young Master asked him to deliver it. Crown Princess, is there any problem?"

"This is not the letter my fourth brother sent." Chu Heyi said, "The content is not, and the handwriting is not."

Baihua was surprised: "What's written in the letter?"

Chu Heyi gave her the letter. After reading it, Baihua was also surprised: "Is this the method of making cement? How can others have this thing? What is the difference between the method written here and the one given by Miss Tong?"

Chu Heyi said: "At first glance, there is not much difference, but there are slight differences in proportion."

Baihua was silent for a while before she said, "But I found that the cement mortar made by Miss Tong is also very useful. I haven't found anything wrong yet. As for this letter, who sent it and what is its purpose?"

Baihua's doubts were exactly Chu Heyi's doubts. She was silent for a long time and said to Baihua: "Don't tell anyone else about this. Only God, the earth, you and I know it."

Baihua nodded solemnly: "I know."

Chu Heyi thought for a moment, then said, "Come with me to Qianqiu Palace to find His Royal Highness the Crown Prince."

When the two of them arrived at the gate of Qianqiu Palace, they were stopped by Wangshan, who said, "Before the results of the identity are known, please stay in Changning Palace, Princess, and don't make things difficult for me."

Chu Heyi said, "I have something important to discuss with the prince, so please get out of the way, Lord Wangshan!"

Wangshan: "Please forgive me for not being able to obey your command!"

Chu Heyi gave Baihua a wink, and Baihua immediately stepped forward and fought with Wangshan. Chu Heyi took the opportunity to enter Qianqiu Palace.

Although it was late at night, Xie Lin had not yet gone to sleep. He sat on the couch with a pile of memorials beside him.

Hearing the sound, he rubbed his eyebrows and looked over. Seeing it was Chu Heyi, he was a little surprised.

Chu Heyi sneered, "It's really difficult to meet His Royal Highness the Crown Prince alone now."

Under Xie Lin's gaze, Chu Heyi stepped forward and handed him the letter: "Someone sent me a letter, which describes the method of making cement, but the proportions are slightly different from what Miss Tong gave.

"The letter was brought back to me by Baihua. The person who delivered the letter said it was written by my fourth brother, but when I looked at the content and the handwriting, it didn't look like my fourth brother's handwriting at all."

Xie Lin took the letter and found that it was indeed the same method of cement production as Chu Heyi said, but the proportions were different.

Chu Heyi said: "I don't know if the cement made with this ratio will be better or worse than Miss Tong's. I don't know who sent it and what the purpose is, so I brought it to you to see."

Xie Lin said: "I will send someone to investigate and see who sent it and what their purpose is. As for whether this method is better or worse, we will find someone to formulate it and we will know after using it."

"Okay." Chu Heyi said, "We must find someone we can trust to do this, and the fewer people who know about it, the better."

Xie Lin said: "I know what's going on."

Chu Heyi nodded, looked at Xie Lin deeply, then turned and walked out the door.

Wangshan and Baihua were still fighting. At first, they only used fists and feet, but now they even drew out their swords.

"Baihua, let's go!" Chu Heyi shouted.

The two seemed not to hear anything and were fighting fiercely, especially Baihua, who was standing up for Chu Heyi and thought that Xie Lin and Wangshan were too abominable, so she used ruthless moves in an attempt to beat Wangshan down.

Chu He thought shouting was useless, so he fell to the ground and screamed, "Ah! It hurts!"

Baihua shuddered when she heard that. She immediately pulled back and helped Chu Heyi up from the ground. "Crown Princess, are you okay?"

Chu Heyi shook his head: "It's okay, it might be an old injury that caused him to fall, just go back and rest for a night and he'll be fine."

Wangshan came over nervously and wanted to check the situation, but Baihua glared at him fiercely and didn't allow him to get close.

Tong Xiling soon got the news that Chu Heyi went to see Xie Lin privately, but was thrown out by Xie Lin, looking very embarrassed.

That's why Tong Xiling didn't go over to investigate the situation in person.

The maidservant next to her said: "When she was thrown out, she fell directly to the ground, and her palms were bleeding. Baihua next to her was so angry that she fought with Wangshan."

Tong Xiling felt relieved after hearing this, and couldn't help guessing, "I made cement, Chu Heyi must have felt a sense of crisis, so he went to find Xie Lin at night. I think Xie Lin must believe that I am the real Crown Princess, so he doesn't like Chu Heyi and doesn't hesitate to throw Chu Heyi out!"

Tong Xiling laughed, with a cold look in her eyes.

She sat on the couch, looking at the boundless moonlight outside the window, the smile on her lips never disappearing.

She thought of Chu Heyi's background - the eldest daughter of the Zhenbei Marquis's Mansion. Her father, eldest brother and fourth brother all doted on her. Her sisters also liked her, and even the second wife of the Zhenbei Marquis's Mansion was very good to her.

She is even the high and mighty Crown Princess of Daqi. Although the emperor is still alive, Daqi is now in the hands of the crown prince. Xie Lin's ascension to the throne is a foregone conclusion, and it is only a matter of time before Chu Heyi becomes the queen.

This woman is not only loved by everyone, but also extremely noble. She is so lucky.

It really makes people jealous.

However, she wanted to take back all the favors that belonged to Chu Heyi, whether it was family affection, love or future status.

Thinking of this, the smile in Tong Xiling's eyes deepened.

Half a month passed quickly.

During this half month, it snowed, there were strong winds, and the sun came out in Shengjing City.

Chu Heyi, Xie Lin and Tong Xiling came to the backyard of Mingde Hall again. They saw that the wall was still standing.

Xie Lin stepped forward, placed his slender hands on the wall and patted it, but the wall showed no signs of crumbling.

Tong Xiling raised his eyebrows and said, "Prince, cement mortar can replace glutinous rice mortar. In this way, we can build roads and city walls. When do you plan to start construction?"

Xie Lin asked: "You want to produce a large amount of cement mortar to build roads and city walls?"

"Of course!" Tong Xiling said, "Building a lot of roads can make the people of Daqi rich; building city walls can resist attacks from enemy countries. In the past, we used glutinous rice mortar, which was too expensive, but now we have cement mortar, it's different."

Xie Lin said: "That makes sense."

Tong Xiling: "Then will you do as I say?"

Xie Lin replied: “Yes.”

Tong Xiling smiled brightly: "Are you sure of my identity now?"
