Nongmen splendid, the master craftsman is three and a half years old

Seeing the other party's frightened look, Man Man said, "Let me guess," she patted the shoulder reassuringly, signaling the other party not to recall any more.

"When and where did you see it?" Looking back at the crowd with hands behind their backs, asked and answered, "The season when you see will-o'-the-wisps is summer, and it's at sunset and dusk!" right?"

Seeing that the other party really nodded, everyone sighed in surprise, and looked at Manman with different expressions from before.

Chen Xiaotong didn't believe it, thinking that the other party must be bluffing, so he choked with disdain, "Master Yu Shan, have you met?"

"I've seen it." Manman nodded with a smile unmoved, "Not only have I seen it, I can let you see it too."

Shaking his head and looking at the crowd, Xu Shanyu said, "The ghost fire is actually a very common phenomenon. It is composed of phosphine. This is a gaseous substance, and its ignition point is very low."

Walking to the stage with his hands behind his back, "Phosphorus is contained in the human body and animals. Why is it in the tomb? Because there are many corpses in the tomb, phosphorus will be produced in the air when it decays and decomposes. Once the temperature is too high, It will spontaneously combust."

Peng Rou looked at Man Man with admiration, "Then why would the ghost fire follow people?"

"This question is very good, you have a strong sense of exploration." Manman now looks at Peng Rou as if she were her disciple, "Actually, the story about the will-o'-the-wisp running with people is wrong, it doesn't follow people, it follows the trend .”

Manman took out the prepared phosphine and smeared it on a dress, and asked her father to put clothes on the straw dummy beside her.

"Phosphorus fire is very light. If there is no wind, people running or walking can drive the airflow. At that time, the speed of the airflow around the person will increase, and the air pressure will also become stronger. Therefore, it will follow the person's body in the eyes of outsiders." Walk."

"Okay, since it's daytime, and the phosphine I extracted is not very pure, but spontaneous combustion is definitely not a problem. Next, I will tell you about light to help it burn faster."

Manman took out a clean mirror and asked people to pass it on, "This is an ordinary vanity mirror," pointing to the clothes on the dummy, "Fortunately, it's sunny today, I used a few mirrors to focus light on the clothes, Let's see what happens."

Jin Baobao took the handheld mirror handed over by the servant, "This is ordinary!"

Manman shook her shoulders, with a natural expression on her face, "For me, it's just normal, well, because it's a bit slow to gather light in spring, I'll show you some other interesting things."

Everyone didn't look impatient at all. Seeing that Manman was still there, they quickly looked at Manman with all their attention.

"Mirage, I think everyone knows it. Of course, I know you think it's a miracle, because you haven't seen it before."

Now that Manman said this, everyone didn't feel insulted at all. In this short quarter of an hour, the proud women of heaven have already admitted their ignorance.

"But you must have seen rainbows. Of course, the principles of their formation are different, but they are all based on the principle of light."

Commanding his father, he moved the other table to the pool next to him. Seeing that the guards were actively stepping forward to help, he turned around and waved to everyone.

"The next step is the physical experiment. If there is no danger, you can get closer and observe carefully."

"Rainbows are dispersion, and mirages are refraction." Manman looked at the crowd and explained, while calculating the angles of the surroundings, adjusting the lights and sprinklers to slowly make the rainbow appear in front of everyone.

"It's a rainbow! I haven't seen one yet."

Chen Xiaotong looked at the colorful bridge that appeared in front of him in surprise, his eyes were full of shock, and there were endless shouts of surprise in his ears.

"Huh!" There was a stubborn cry, but he didn't want to move his eyes away from the hazy colorful light for a moment.

As the master, Wen Fuxiang exclaimed, "It's exactly the same as the one I saw in Qixia Mountain back then, exactly the same."

"Okay, everyone, go back to the yard, the phosphorous fire should be kindled." Seeing that everyone was reluctant to give up but they were all obedient, Man Man compared herself with Da Fu in her heart with satisfaction.

Uncovering Yuanzhi who had been covering it all the time, the nine-foot-high bright mirror suddenly appeared in front of everyone. The scarecrow was an angle that Manman had designed long ago.

A few extra mirrors next to it directly refracted the sunlight from the west on Yuanzhi, and the strong light hit the scarecrow. There was no wind or fire, and it ignited spontaneously with a "boom".

With a sound of "wow", everyone's blood seemed to flow backwards, both fearful and excited for no reason.

"Look, there is writing on the mirror!"

"What, really!"

Looking at the four-character motto that emerged, Ji Yue's perennially peaceful heart suddenly rippled, and her breath of book rhyme also began to rush, "Wizards in heaven, geniuses in heaven!"

With a trembling hand sideways, he patted the supporting maid, "I will repeat what happened today to my brother."

"Yes."

Listening to the maid's whisper, Lin Lan looked back at Ji Jiaoyu, whom she had never seen in a hundred years, and walked forward quickly, "Sister Yue is here too, but is this noisy to you?"

"I heard that this person was recommended by the dean?"

Lin Lan understood what the other party meant, "This person is the manufacturer of Manni's textile workshop, and the dean learned about Manman's bold words at that time."

"I also saw that the local government order strongly recommended it, so I issued an order to hire someone to serve as the head of Qiaoyuan Mountain."

Looking back at Man Man, who was highly praised in the center, "I didn't expect this person's knowledge and skills to be so amazing."

Looking up at the other party's penetrating and wise eyes, with a firm smile on her face, "She is just a commoner, and has nothing to do with the bloody storm above the temple."

"Others are curious about her parentage, but who can stipulate that ordinary people must be illiterate and vulgar?"

"She's fine." Ji Yue turned around holding the maid's hand. "Listening to her words today, I feel more and more old. Alan, I wonder if we still have time to see the world she describes."

"Of course, Manman said that one person's strength is limited, but our academy has so many outstanding juniors, and when this generation is cultivated, that era will definitely speed up towards us."

Ji Yue shook her head, looking at the orange afterglow, "Not enough."

Lin Lan looked at the leaving figure, "It's not enough, but." Looking back at the lively Manman, she chuckled, "She's still young."

Manman broke away from the crowd, "Father, hurry up, Auntie must have prepared a lot of delicious food for us."

Damo watched Mo Shu and his disciples stand in front of him, and then got out.

"Ladies and gentlemen, don't rob. Our mountain chief said that the official assessment will be on March [-]th. Now you can only enter the T-class class."

Mo Shu stopped a group of crazy ladies with a loudspeaker, and quickly winked at the two disciples beside him, "It's too late now, ladies, go home quickly, go home."

Jin Baobao found that Manman was gone, and he didn't want to fight with a group of crazy women, so he dragged Peng Rou who refused to leave, and ran to the mirror stand, "Good thing! This mirror, this fire phoenix, is simply a treasure!"
