The butler had never been on a battlefield, so he didn't know that there was such a thing as powerful gunpowder, but Chu Yunyao, who had personally developed and improved gunpowder, now knew better than anyone that it was gunpowder.

This is a gunpowder that is extremely lethal on the battlefield and causes the opponent's troops to be disabled.

Mo Lingyuan handed the child to Chu Yunyao: "You and Siyu are here, I'll save them."

Chu Yunyao held him back: "But..."

"Don't worry, the house has burned down, but there has been no explosion, so there should be nothing wrong." Mo Lingyuan moved closer to her cochlea: "If you stand far away, you can see more clearly, who is the arsonist?" .”

After he finished speaking, he took off his outer shirt, soaked in the water basin, and rushed into the sea of ​​fire.

Holding Siyu in her arms, Chu Yunyao watched the fire burn more and more, the flames licked the beams of the house, and the beams collapsed, almost hitting the guards and servants who escaped from the flames...

Mo Lingyuan, dressed in black, walked in and out of the house destroyed by the fire...

Until the white belly of the east is exposed, the morning sun penetrates the darkness, and the light shines down from the sky.

The tired housekeeper and Duan Changyu took the roster and counted the people in the mansion one by one.

Those who were injured were all the old people who had poor legs and feet in the shop next door who were involved in the fire. Fortunately, they were all rescued in time.

Chu Yunyao handed Siyu to Bao'er to hold her, squatted in the crowd, took their pulses, and prescribed a prescription, and ordered the guards to come over with the medicine box and give them the medicine herself.

After settling these injured old servants, Mo Lingyuan began to investigate the cause of the fire.

"Who lives in that wing?" Mo Lingyuan looked at the house that had been destroyed by the fire.

"It's been empty all the time, and no one lives in it." The housekeeper said, "It's a place where groceries are piled up on weekdays, and it's impossible to catch fire. Could it be that someone threw the oil lamp in there?"

There was a heavy rain just a few days ago. It was the rainy season, and the air was humid. It was impossible for this fire to start for no apparent reason. After so many people worked together to put it out, it was still burned to ashes.

Mo Lingyuan asked: "Have any irrelevant people visited this mansion recently?"

The housekeeper thought for a while: "No, the young lady told me before leaving that no strangers are allowed to come in. The old slave has always followed the young lady's order."

Chu Yunyao reached out, took the roster from the housekeeper, flipped through the pages, and asked inadvertently, "Who made the purchases for the last month?"

The butler raised his hand and nodded to the servants in charge of purchasing: "Now they are Lao Zhuo and his son. Last time Lao Zhuo twisted his leg, he asked Xiao Zhuozi and Xiaonianzi to go out and buy."

Sitting cross-legged on the ground, the young man wiped off the dust on his face: "There is also Mammy Xu, I went out with Xiao Zhuozi half a month ago, and Nanny Xu said that the temperature has fluctuated too much recently, and several old nanny were sick , went out to buy some medicine...I took Mother Xu to the street..."

Mo Lingyuan's eyes were like sharp knives, looking at the ashen-faced and tattered Nanny Xu, and said coldly: "Search for me, find out the people hiding in this mansion."

housekeeper:"......"

The butler was shocked: "Master, this mansion is locked every day when the sun goes down, and the guards are guarding the door. They will never let an irrelevant person in easily. How could it be..."

Chu Yunyao asked softly: "Mother Xu, you are an old man in the mansion. You have never married or had children in your life. Who did you bring into the mansion?"

Mother Xu: "..."

After a while of silence, Madam Xu lowered her head even more, her voice was like a mosquito ant: "Young Madam, I have been wronged, the entire Young Master Mo's Mansion is guarded by three floors of guards inside and three floors outside, even if I want to bring someone in , and couldn’t find a chance.”
