Bao Heizi nodded repeatedly. When he heard Xiaoyuer grasping the key to the problem, he began to believe that he really had a solution. He couldn't help but be very excited and asked: "How to identify whether the fetus has breathed?"

"There is a way!" Zhang Yu coughed twice. We don't know the specific forensic terms, but we learned the biology course in high school (everyone understands it), and then continued: "Before the fetus was born, it mainly relies on the mother's placenta to provide the nutrients needed. After birth, the umbilical cord is cut off, and the placenta circulation will stop. If the fetus is alive, the midwife will pat the pink buttocks of the newborn baby. The baby who suffers from pain will cry. Under normal circumstances, they will start to breathe independently, and the main organ of breathing is the human lungs. The lungs that have been breathing will have important and obvious changes. The lung capacity increases and the weight increases. Morphologically, the front edge of the two lungs will cover part of the heart, the edges are blunt and round, the color is light, and the surface looks similar to marble patterns. The touch is elastic and the hair twisting..."

This series of medical terms made Bao Heizi dizzy and couldn't understand it, and it was difficult to interrupt him.

Xiaoyuer continued to say: "If it is a stillbirth and the lungs have not undergone spontaneous breathing, the lung capacity will be very small, forming atrophic, sharp and thin edges, smooth surface, and look a bit like the liver, without elasticity, and no sense of twisting hair, it is dark purple-red..."

Bao Heizi finally couldn't help but interrupt him: "Wait, what you said just now is too complicated. Master... Master, I don't understand... Is there a simple way?"

Xiao Yuer also realized that she was in the Song Dynasty, not in biology classes, and she didn't need to explain why, she just needed to tell them what to do. She smiled and said, "The easiest way to distinguish between live birth or stillbirth is to conduct lung agitation test."

"Lung...What's the lung?"

"Lung Floating Test!" Xiao Yuer said word by word, "There is no air in the lungs that have not been breathed, so it is solid and has a specific gravity greater than one. The lungs that have breathed contain air and increase in volume, and the specific gravity less than one. The lungs that have risen are performed according to this principle."

"Compared with...compared with gravity?" Bao Heizi stuttered.

Xiao Yuer slapped her forehead. It seemed that she would still have to consider speaking in the future. Modern society is common knowledge of physics in middle schools, but in ancient times, it became ghost painting talismans, and she couldn't understand it or read it.

Xiaoyuer thought for a while before saying, "In one sentence, cut the fetus's chest open and take out the lungs. Remember to tie the trachea with a thread first, and then cut the trachea. Put the lung lobes in clean water to observe. If they sink, it means it is stillbirth. If it floats on the water, it means it is a live birth!"

Bao Heizi was the smartest person in the Song Dynasty after all, and he quickly understood that this was indeed different.

"Bang!!!" The slap of the goblin. Bao Heizi snarled: "Zhang Long!!"

Zhang Long stepped forward and clasped his fists and said, "I am here."

"Zhang Long, you will be looking around with a group of yamen runners to see which newborn babies died of life, and which one has a stillborn baby. You must bring them with kind words, including dead babies."

Zhang Long was a little confused. After hearing Xiao Yuer's words, wasn't this just messing around? He asked weakly: "Sir, this is probably inappropriate?"

"Uh, just say, this is for solving the case. I have a reward." Mr. Bao thought for a while and said, "Send them a archway."

"Yes." Zhang Long had no choice but to bite the bullet.

Then Bao Heizi discussed the case with Xiao Yuer.

In less than an hour, Zhang Long came back with the yamen runners, and there were a few ordinary people behind him, holding things in his arms.

"Damn, so many." Xiao Yuer was shocked. There were people outside the door.

Zhang Long stepped forward and clasped his fists and said, "Sir, this is the baby who has just been born in these days."

Bao Heizi looked at everyone, but they didn't understand why, but they were all sad. After all, it was not easy for a new life to be pregnant for 10 months. When they were about to be born, they died.

"My elders, my parents know that you have died and feel sad. My parents also burst into tears. However, people cannot be resurrected by death. I hope you will be mourning and following the changes."

Those parents felt much more comfortable when they heard this.

Bao Heizi continued: "However, at this time the case is related to the reputation and destiny of a Wenpo. It requires the cooperation of everyone. Maybe this case will be left to the history of Qingming."

"Okay, sir, since you can use it, let them use their remaining energy for the Song Dynasty. It's not in vain to come to this world once."

Xiao Yuer pulled Zhang Long aside and asked, "Brother Long, why are there so many? You've been out for less than an hour?"

Zhang Long said proudly: "This is not simple. I asked the yamen runners to look for the stable women in the county separately, and I will know as soon as I ask."

"Oh." Zhang Yu was surprised. He was indeed very smart.

The case was soon revealed under the arrangement of Lord Bao. The yamen offender opened the chest of Boss Liu's fetus on the spot, took out the lungs and put them in the water to observe, and it immediately sank to the bottom of the water. Then, the lungs of the corpses of the babies who had lived for a day and the dead babies who had been stillborn were also put in the water to observe. The lungs of the babies who had lived for a day were floating on the water. All the lungs of the stillborn were sinking to the bottom of the water.

Seeing this, Boss Liu's concubine was so panicked that she seemed to have seen a ghost. We immediately guessed that the concubine had a ghost in her heart. She immediately interrogated the two maids who made fake certificates. They also saw the test process and confessed before they could be executed. It turned out that they were bought by Boss Liu's concubine and made fake certificates, and falsely accused Wen Po of slapping the newly born young master to death so that they could be promoted to their wife."

"Bang!!!" gave the awkward slap.

"Liu Neng, do you know that your child is stillborn now? My parents know that you are very sad, and I am also very sad. However, no matter how sad it is, there is no mother. My parents think of the pain of the mother losing her child, so they will not pursue the crime."

"Thank you for your kindness, thank you for your kindness." Liu Neng looked a little lonely after knowing that his child was stillbirth. However, when he heard that Mr. Bao would not pursue the matter, he was very grateful.

Bao Heizi said: "But, Feng was hurt by you after all, the cost of the decoction and the settlement fee..."

Liu Neng naturally kowtowed and said, "I will give it, I will give it."

"Sir." Feng said sternly: "I don't want your stinky money. I just want your apology. Why did you leave me behind and take that vixen?"

"This, this" Liu Nengyu was incoherent. Others called her stupid, but in Xiaoyuer's eyes, this is the integrity. But for the reason, it has nothing to do with this case. Bao Heizi was about to announce his withdrawal.

"Slow down!!!" someone suddenly said.
