Siheyuan.

Lu Ruoling stayed here with Jiaojiao for a day, but Yang Niannian didn't come back in the evening. She was very worried and didn't know how Yang Niannian was doing, but she had no way to help.

At night, Jiaojiao was sleepy. Just as she coaxed Jiaojiao to sleep, she heard Xiaohei calling out at the gate of the yard. The call was so loud and fierce that even Qian Hongzhi and others felt that something was wrong.

"What's going on with Xiao Hei? Why is he yelling so loudly?" Qian Hongxiang was a little scared by Xiao Hei's yelling.

Qian Hongzhi was also worried. "Xiao Hei is a smart dog. He won't bark for no reason. I'll open the door and see what's going on."

Lu Ruoling just came out of the house. Xiao Hei was barking very loudly. She felt very uneasy and shouted quickly.

"Sister Qian, wait a moment." She ran to the kitchen with a rolling pin, stood behind the door, and said bravely, "Okay, open the door!"

Seeing this, Qian Hongzhi asked Qian Hongxiang and Sister Li to stand at the door with things in their hands. Sister Li didn't know what to take, so she simply took a kitchen knife. She didn't dare to cut anyone, but it was good to scare the bad guys.

Everything was ready, and Qian Hongzhi finally opened the door. However, she pulled the door, but it didn't open. She thought she didn't use enough force, so she tried a little harder, but it still opened. She tried several times but failed.

She had a bad feeling in her heart, "Who locked the door from the outside?"

When these words were spoken, everyone panicked, put down their things and tried to pull the door, but it didn't open.

The door was locked late at night, so something bad must have happened. Xiao Hei was still barking fiercely towards the outside of the yard. Qian Hongzhi was a little anxious, so she said.

"Ruoling, I remember there is a phone book in Nian Nian's room with many phone numbers written on it. Why don't you call Mr. Yu? He is from Beijing and can come over to see what's going on in time."

Lu Ruoling didn't have time to think about it, and hurried to Yang Niannian's room, took out the phone book from the drawer, and quickly found Yu Sui's number. After just two dials, the call was picked up.

Without waiting for the other end to speak, Lu Ruoling spoke anxiously in a crying voice.

"Mr. Yu, I'm Lu Ruoling, Yang Niannian's sister-in-law. My second brother is in the army, and Feng Yi is accompanying my second sister-in-law to the hospital. Now someone has locked the door from the outside, and I don't know what they want to do. There are only me, Sister Qian, and a few other women and children at home. We don't know what to do. Can you come over and take a look?"

The person who answered the phone was Yu Zhian. Before he could say anything, his face suddenly changed after hearing what Lu Ruoling said, and he quickly said.

"Hurry up and grab the things to protect yourselves and take good care of the children. I'll be there soon."

Yu Sui heard what his father said and asked.

"Dad, who called? What happened?"

Yu Zhian hung up the phone without saying anything more and spoke directly.

"I don't know what others are planning to do, but they have locked the door to Commander Lu's house from the outside. There are only a few women and children at home now. We have to hurry over."

Without waiting for Yu Sui to speak, he turned to look at his wife and said, "Hurry up and report the case to the police. Tell the police to go to Commander Lu's house."

Yu's mother was confused, "Where does Master Lu live?"

Yu Sui casually gave the address and followed his father out of the house. The two of them rode their 28-bar bicycles towards the courtyard without stopping to catch their breath along the way.

Locking the gate of the courtyard late at night means that they have no good intentions and are not going to let anyone inside go.

What if something goes wrong?

This side of the courtyard.

Qian Hongzhi still wanted to try whether she could open the door, but Qian Hongxiang suddenly said something strange.

"What's that smell? Why does it smell a bit like diesel?"

When these words were spoken, Qian Hongzhi and Sister Li both broke out in cold sweats. Someone locked the door late at night, and there was a smell of diesel outside. Did someone want to burn them to death?

Qian Hongzhi had been with Yang Niannian for a long time and had learned to stay calm when encountering things. She suddenly remembered that there was a wooden ladder in the utility room, so she said.

"There's a ladder in the utility room. I'll move it out to see what's going on outside."

Qian Hongxiang was also afraid that someone outside might start a fire, so she hurried in to help move the ladder.

Sister Li was worried about the children, so she ran back to the house to check on them. Seeing that the three children were still sleeping, she ran to the yard and saw that Qian Hongzhi had just put the ladder away, and Xiao Hei used the ladder to jump directly over the wall.

Then I heard a man wailing in pain outside.

After confirming that there was really someone outside, Qian Hongzhi became even more frightened. She climbed up the wall with a ladder and a flashlight, and saw Xiao Hei pounce on a man and bite his calf hard and refused to let go.

Another man wanted to stab Xiao Hei with a knife, but Xiao Hei dodged. Then, Xiao Hei pounced on the man with the knife, but was stabbed in the hind leg by the knife in the man's hand.

Xiao Hei acted as if he didn't feel any pain. He first bit the man's hand holding the knife, and then bit the man's thigh tightly. The two men quickly lost their fighting ability and lay on the ground wailing.

When Qian Hongzhi saw that the two men had been subdued, she wanted to jump over the wall to help Xiao Hei, but when she saw how high the wall was, she became a little scared.

Seeing Qian Hongzhi standing on the ladder and not daring to move, Lu Ruoling said.

"Sister Qian, come down and I'll climb over the wall. I used to climb trees when I was a kid and I'm not afraid of heights."

After hearing this, Qian Hongzhi came down from the ladder. Lu Ruoling took the flashlight from her hand and swiftly climbed to the top of the wall. When she saw the scene outside the wall, she was so scared that her legs went weak.

Seeing that both of them were completely subdued by Xiao Hei, she mustered up the courage to go down, quickly pulled out the iron rod stuck in the door, and pushed open the gate.

Qian Hongzhi and several others came out with weapons in their hands, only to find that their legs had been bitten off by Xiao Hei. They lay on the ground crying "ouch ouch" and dared not move. The knife in his hand had also been taken away by Xiao Hei.

Xiao Hei was lying on his side, licking the injured area. Lu Ruoling walked closer and found that Xiao Hei was injured.

She said in a crying voice.

"Sister Qian, please get some gauze out, Xiao Hei is injured."

Upon hearing this, Qian Hongzhi quickly ran back to the house and got out the medicine box to bandage Xiao Hei. Qian Hongxiang and Sister Li held sticks and watched the two men to prevent them from escaping.

After Qian Hongzhi finished bandaging Xiao Hei, she said.

"You guys keep an eye on them first, I'll go call the police."

As soon as he finished speaking, a group of public security personnel arrived on bicycles. When they saw the two people lying on the ground and the diesel barrel thrown in the corner, they instantly understood something.

They were directly divided into two groups, one group escorted the two people to the hospital, and the other group stayed to protect Qian Hongzhi and others, and investigate the situation at the same time.

When the few people saw the police coming, they felt relieved but also scared.

Qian Hongzhi described the situation at that time in a trembling voice, and then said with lingering fear.

"Luckily, we have Xiao Hei. If it weren't for Xiao Hei, I think these two bad guys would have already started the fire."
