Hearing Chen Mo ask about the bachelor surnamed Liu, Yan Man and Qian were stunned at the same time, but Ruohan asked in surprise: "Is Uncle Liu also here?" Great, I haven't seen him for a few days, and the slave family wants to kill him! ”

"Don't talk nonsense, kids!" Qian glared at Ruohan, a little embarrassed.

Yan Man said: "Duke Yin almost forgot about him without mentioning it, so he sent someone to release him...... Now that he has found Xiao Ruohan, it is natural to return his innocence. ”

The surname Liu is called Liu Fu, and his name is very ordinary, and it is much more interesting with the word "Tianci".

This is an unkempt person, with a scruffy beard, unkempt hair like a bird's nest, and a strange smell exuding from his body, as soon as he came in, Qian covered his nose, but he didn't hold Xiao Ruohan, and at this moment he was holding his hand and standing next to him with a smile, and said to Chen Mo:

"Master, Uncle Liu is amazing, he can use ice cubes to make a fire, and he can use a piece of tissue paper to hold the water in the cup without falling down......" and Yourong looked like she was talking about herself.

"Still called master? You want to call my brother, you know? Chen Mo smiled and corrected Xiao Ruohan's title.

Ruohan stuck out his tongue: "I'm happy, the slave family forgot!" ”

"Don't say anything wrong in the future, or my brother will spank you." Chen Mo said, dragged Ruohan into his arms, touched her head with a smile, glanced at Liu Fu's proud appearance, and said to Ruohan:

"Ice cubes to make fire, in fact, my brother will, as long as the water is clean enough, put it in a bowl and freeze it, choose a good noon in winter, adjust the angle and height to the daylight, and put some dried cotton leaves and the like below. Wait patiently, and soon you will be able to light a fire. As for the tissue paper holding water. It's even simpler, as long as the cup is full. Cover with paper and be careful when flipping, anyone can do it......"

Chen Mo's later life is indeed inferior to the liberal arts, but the simple lens principle and atmospheric pressure are still known. As he narrated, Liu Fu's arrogance gradually faded, replaced by a touch of surprise, and finally couldn't help it, and asked, "Where did the master know this?" ”

Future generations will know that it's okay, right?

Chen Mo was secretly proud. smiled indifferently: "Don't care where our family knows about it, just tell me, is what our family said right?" ”

"All right!" Liu Fu nodded again and again, and then said: "Actually, it's nothing, the villain has recently collected some colorless and odorless gas, which can burn with a spark, if the master can tell what it is, the villain really admires it." ”

Hydrogen?

Chen Mo was ecstatic, and said in his heart that he had really picked up a treasure. Qiang suppressed his inner excitement and asked quietly, "How did you collect it?" Green mercury oil with iron filings? "Mercury oil is the ancient Chinese name for sulfuric acid, Tang Gaozong had an alchemist named Gu Gangzi in his work talked about the "refining stone gall extract method", that is, the method of dry distillation of gall gong to obtain sulfuric acid. Although he has not seen the original book, he has seen the record of this matter in the historical books.

Liu Fu was dumbfounded, his mouth wide open. It was enough to stuff an egg, and after a long time, he said like a ghost: "Does the master really know?" The villain did use amalgam. However, no iron filings were used. Could it be that iron filings can also produce that kind of gas when they come into contact with amalgam oil? ”

In later generations, he had done experiments in this area when he was in school, so Chen Mo nodded affirmatively, and it was already certain that Liu Fu in front of him was indeed a fanatical chemist, and he couldn't help but be more determined to use it for his own purposes, and said: "Our family has also collected that kind of gas, which is called light gas, and it will burn when it meets fire." In addition, we can tell you with certainty that the air we breathe is actually composed of many invisible tiny components, for example, there is a gas in it, although it cannot burn, but it has the effect of combustion...... If you are interested, go back to Zhaoling with our family, and we will discuss it when we are free......"

"Is the master really willing to teach?" Liu Fu was surprised and delighted, a little incredulous.

"I can't talk about teaching, and our family knows a limited amount, but I'm interested in this area, and I'm so happy to finally meet you, a bosom friend!"

Liu Fu's hobby is not tolerated in the world, and he is looked at differently, although he doesn't say anything on the surface, but in fact he still has some pimples in his heart, and now he listens to Chen Mo actually citing him as a bosom friend, he can't help but have the idea of meeting a confidant, nodding like pecking rice, and said in a stacked voice: "It's rare for the master to look at it, anyway, the villain is a single person, and he has nothing to worry about, so he will return to the mausoleum with the master." ”

The two talked, Yan Man and Qian Ruohan listened to the book of heaven, and when they heard this, they finally had a conversation, Yan Man smiled and said: "Congratulations to Yin Gong for recruiting good talents, you can't understand every time you say it, what gas, flammable, I want to see it if I have the opportunity." ”

"The slave family also needs to see!" Ruohan blinked his big sparkling eyes and said.

Chen Mo smiled and glanced at Liu Fu: "Don't worry, it will definitely open your eyes!" ”

Liu Fu in Huanghua Town still had a lot of jars and jars to clean up, and he said that he would go to Zhaoling to find Chen Mo as soon as possible and then leave.

Chen Mo was thinking about the meeting of Zhang Feng Group tomorrow evening, and told Yan Man to make preparations early and return to Zhaoling with Qian and Xiao Ruohan. first went to Wang's sister-in-law's house to settle the two of them, told Caiyu all about last night in a few words, and then went back to the tomb to find Feng Bao.

When he arrived at the mausoleum, he was empty, and the little fire attendant said that Feng Bao went to the hot air balloon base outside the prison, and he was busy going out of the mausoleum.

The so-called hot air balloon base was secretly built under the instruction of Zhu Yijun and Empress Dowager Li, Chen Mo was the first admiral of the base, Lao Zhao and Lao Liu were responsible for organizing people to make improved hot air balloons, and 50 elites were selected by the guards of the tomb as the first batch of hot air balloon troops to participate in training.

After more than a month of intense work, three hot air balloons have been made, successfully flown and put into use, which can be regarded as beginning to take shape.

Feng Bao had long foreseen the bright future of this special force that had not yet taken shape, and was bent on firmly grasping it in Chen Mo's hands, making it a powerful hole card for Chen Mo in the future.

Some distance from the mausoleum, the base is a clearing carved out of a mountain col, surrounded by dense hazelnut forests, which are really difficult to find without guidance.

Riding a horse through the woods from the path, the eyes suddenly opened up, and on the rattan chair in front of the wooden house built in the north of the mountain pass, Feng Bao was leisurely basking in the sun. Chen Mo hurriedly dismounted and strode over.

"Grandfather, the child is back!"

Chen Mo greeted him with a smile, and was about to pull a chair and sit down, when he saw Feng Bao sitting up straight and looking at him coldly, and said solemnly: "Kneel!" couldn't help but stiffen his face, and when he caught a glimpse of Huo Dong, who came back before him, standing far away next to a hot air balloon and snorting something, he smiled bitterly and knelt down honestly.
