Xiao Ruoyuan saw Li Yuanying's stunned appearance, and felt that the marks on his face were not so painful, and his mood was much more relaxed. continued: "And Yin Qi can be stripped out! ”

Li Yuanying raised his hand and slapped his forehead fiercely...... It hurts, it's not a dream! Can...... Can...... This is not scientific! Now it is the Tang Dynasty, the Tang Dynasty is a feudal society dominated by agriculture, although science and technology are developing rapidly, but it is not as good as the later Ming and Qing dynasties, it can only be regarded as the initial growth stage after germination, how can it be separated from oxygen?

No one has ever distilled the wine!

The pain made people sober, and Li Yuanying pinched the soft flesh on the inner wall of his arm without hesitation...... The pain passed a little before he asked, "Have you ever stripped it out?" ”

A fanciful theory cannot be called a theory, it can only be regarded as a conjecture, and only when it has been verified by experiments can it become a real theory.

"Ban Da and Liu Er have experimented, it can be compressed to a state similar to water, and we don't have a clue how to do it further, until Ban Da sees the ruler diagram of the steam engine." Xiao Ruoyuan's handsome face showed a smile, but it was like a flash in the pan, fleeting...... You can't laugh, and it's easy to get wrinkles if you laugh too much, said softly. "It has been successfully peeled out, and behind the scroll is a white light that has been successfully tested, and the brightness is barely usable, which can help King Teng achieve a bright Chang'an."

Li Yuanying: "......"

In the original historical line, the Tang Dynasty alchemist Ma He (also translated as Mao Hua) recorded the research results of his life in a book called Ping Longzhi, and the description of the air is exactly the same as Xiao Ruoyuan, which is no different. He discovered that Yin Qi could be burned along with combustibles, expelling it from the air. However, Yang Qi can still remain in the air unharmed, which shows that Yin Qi can be burned, but Yang Qi cannot burn.

He further pointed out that yin energy exists in substances such as bluestone (oxide) and fire nitrate (nitrate), and as long as they are heated with fire, yin energy can be released. It is also believed that there is a large amount of yin qi in the water, but it is difficult to release it.

Pinglong Zhi has a total of 68 pages, published in the first year of the reign of Emperor Suzong of the Tang Dynasty (756), and has been circulating until the Qing Dynasty. These major discoveries in oxygen research predate Europe by more than 1,000 years. Ironically, the book is a work on Chinese Tang Dynasty Kanyu that was mentioned in an academic paper published in 1807 by the German Imperial orientalist Julius Kraprot. And apart from his mention, there is no record of this book or the physical hand-me-down.

No one knows how many precious artifacts we lost in those two YP wars.

"White light?" Li Yuanying dragged back his train of thought, walked over and carefully looked at the contents on the scroll, and when he saw the device that stripped off the so-called yin qi, he blinked his eyes and warned himself: Determination, must be determined! There are many people in Datang, and many people like to hide in the mountains, and they are bored to engage in research and development just to become immortals, and it is normal to make a set of distillation devices.

In fact, as early as the Shang Dynasty, a steam pillar copper retort was unearthed from the tomb of the woman in Yinxu in Anyang, which is considered to be the earliest distiller in China; In 2016, a major archaeological discovery unearthed a distiller from the tomb of the Marquis of Hailun in the Western Han Dynasty, which was large in size and complex in structure, because there was grain remaining in the still, and it was unearthed in the tomb wine warehouse, it was considered to be a vessel for distilling liquor; The Shanghai Museum also has a set of Eastern Han Dynasty stills, which have been experimentally proven to be able to distill soju...... As for other details, the steam engine Ban Qian can communicate with Xiao Ruoyuan, know the latest glass production method, small case, don't compete with geniuses, except for injury, you can't get anything.

As for why he knew about the news, hehe, he couldn't remember how many books the librarian had read. Not to mention, I have to hold various exchange meetings from time to time to discuss the sorting and numbering of ancient books and cultural relics with various gods.

"Huh?" Li Yuanying's gaze stopped at the back, the so-called white light graphic is really, really similar to the gas lamp of later generations. At this time, only the words of the big fat orange can express the mood at this time: How many surprises do you have ...... I don't know!

Who is the big fat orange, please search for it yourself, the sweet potatoes that have not appeared in the Tang Dynasty have not yet appeared, and they are resolutely not watered, because they don't like sweet potato porridge!

"What is kerose?" Li Yuanying asked knowingly. Cui Ruoyuan can refine the oil, there will inevitably be asphalt, asphalt paving has more advantages than cement paving, paved by asphalt mixed with stones, belongs to the flexible pavement. It can also be paved continuously, and the front paving is flattened with a roller behind the paving, so the whole road surface has a particularly good continuity and a very high flatness. What's more, although the asphalt pavement has a short lifespan, it is very easy to repair after a problem...... So, pavers and rollers go up.

The corners of Xiao Ruoyuan's mouth rose by a small arc, and said: "Liu Er extracted it from the stone paint, and the Shushan Sword Sect's outdoor lighting uses this oil, which can withstand wind and rain better than candles." ”

"Is there a specific gauge diagram for the white light?" Li Yuanying sat on the low couch beside him, picked up the teacup and drank it all, he was too excited and a little thirsty just now...... Continue asking, "How long will the light last?" ”

If it can reach three hours, it can be used completely, and there will be no problems with the production of glass, but you need to consider the wind, or the situation of the explosion.

Xiao Ruoyuan rolled up the scroll, and said lightly: "According to a certain calculation, it can be eight hours, considering the deviation of the production process, there is no problem with six hours." ”

Li Yuanying blinked, eight hours? What are you? Are you teasing so-and-so again? He said in a particularly calm tone: "So-and-so tells you, if you lie, so-and-so will let you know what a kitchen knife and a brick of justice are." ”

"I'm more interested in throwing axes." Xiao Ruoyuan smiled casually...... And he took out a bronze sword to shine on his miserable face.

Yuan Tiangang: "......"

Constantly doubting life: a certain has become an ornament? Something has become an ornament? Certain...... Became an ornament?

"King Teng, the viscosity of the dregs extracted from the fire oil is very high, and the waterproof and anti-corrosion effect should also be good. Yuan Tiangang smiled.

"Oh? The viscosity is very high! Li Yuanying expressed surprise very cooperatively, and said with some excitement. Yuan Gong, I don't know if it can be paved with gravel mixed together, maybe it is more suitable than lime. ”

This time, Xiao Ruoyuan looked at Li Yuanying blankly, King Teng has something, it's not that kind of straw bale prince, no wonder Yuan Tiangang and Gongsun Bai are willing to stay by his side? Originally, I thought that they followed him, just because others were stupid and easy to manipulate...... It is quite possible that the facts are somewhat different.

Yuan Tiangang smiled and said gently: "There are a lot of stone paints in Yanchuan and Jiuquan, we can try it a few more times." ”

Xiao Ruoyuan: "......"
