Xia Gua silently helped the four Lang Jun add tea...... The Hidden Sword Hall fell into an eerie silence again, only the sound of water on the stove seemed quieter and more solemn and depressing...... I really want to say goodbye to the prince, and change someone to guard the Tibetan Sword Hall: it's too difficult to be a slave!

After being silent for half an hour, Yuan Tiangang let out a long sigh and said, "Go find King Teng." ”

Random guessing and research without any direction is indeed a headache...... King Teng, as the Yunhe Order, helped to come up with an idea, or assigned someone to study those stones, which was a matter of duty.

…… Why did a certain original agree to the order of Yunhe, the director of Jinyang Gong? The brain was kicked by the donkey! The order of Yunhe Mansion must be King Teng, no matter who ascends the throne in the future, his position cannot be moved...... Wait, the people of the royal family are basically widowed and sick, if King Teng is also beautiful and has countless concubines, it will definitely affect the affairs of Yunhe Mansion

…… We have to think of a way, how can we better balance the affairs of Beauty and Yunhe Mansion?

"Let's talk about it at dinner." Yuan Tiangang sat down a little dejectedly, the most important thing at the moment is not to let King Teng avoid the matter of Yunhe Mansion and the five of us.

Du Che blinked his eyes and took out the turtle shell to shake the copper coin...... Surprised: "It turned out to be a hexagram, the heavy rain poured snow all over the sky, the pedestrians on the road were bitter and cold, dragging mud and water to pay their best, and they were unsatisfactory and patient...... Wait, the heavy rain is full of snow, the countries in the Western Regions are more drought and less rain, and the Beihai is mostly grassland, which does not meet the requirements of the lower gen, then only Tuyuhun and Tubo are left, is there a surprise in the mountain lakes in these two places? ”

"The largest mountain lake in Tuyuhun is Qinghai on the edge of Fuqi City, but the water there is salty, like seawater, and it is not suitable for drinking." Li Jing rubbed his head and walked in, and said in a hoarse voice. It's not that I have a headache from drinking, but from a loud chanting, a buzzing in my head and a sore throat.

ps: People who have shouted wheat should understand this feeling, especially when they are drunk, and they will have a lasting stamina.

"Yuan Gong has a good amount of wine." After Li Jing sat down, he picked up the tea that Xia Gua had just put and drank it in one gulp...... Surprised, "Hey, the aroma is good, where is this tea?" ”

Xia Gua poured another cup of tea and laughed softly: "Back to the long history, Jun Mountain, which is collected from the center of Dongting Lake, is named Biluochun because it curls up like a snail and has a hidden fragrance of flowers and fruits." ”

Yuan Tiangang: "......"

Eccentric eye, summer melon eccentric eye, when we drink tea, there is no explanation of these...... Does the little girl have an opinion about us?

"The view is really good." Li Jing picked up the teacup and continued to drink tea, the throat moistening effect was obvious, and he felt that his throat was not so painful. looked at Yuan Tiangang and asked. "What are you studying, and you still need to calculate the direction of the hexagram?"

Yuan Tiangang described the matter in general, and said helplessly: "There are no relevant classics, we belong to digging lakes and mountains on flat land, but we don't know where to start, and if we don't have a solution, we can only count a hexagram." ”

Looking at Feng Shui, there will be no hesitation. Even if it was the mechanism that went to break the ancient tomb with Zhang Guo, there would be no hesitation. This...... Looking for new substances to produce lightning ...... "Before reading Du Shiro's drawings, I didn't think about it, and lightning was derived...... The five thunder talismans are not counted, they are exorcism and evil spirits, and they cannot be used by ordinary people. ”

It's not that the talismans are useless, how to say it, it's like asking the inscriptions of the students of the Hongwen Pavilion to be written at the level of the Burrow's inscription, which is unrealistic.

After listening to Yuan Tiangang's words, Li Jing took the ruler diagram and looked at it, frowned tightly and said, "Yuan Gong, are you a little unsure of the priorities?" The steam engine is very useful, and everyone has seen its value. You should first do a good job of the steam engine, so that it can be used for water transportation and sea transportation, and then make a steam locomotive, so that the transportation of grain, grass and bulk goods can get rid of the use of a large amount of manpower and animal power, and contribute to the development of Datang. ”

After drinking another cup of tea, he continued: "How long does the fire oil steam engine you are talking about need to be studied before it can be used? Three, five, or ten years? The steam locomotive and ship moved, and the sound of Tang pear was memorized, and it would be ten years before more talents would join Yunhe Mansion and join the court. Today's problems may no longer be difficult to solve. ”

King Teng has fried the lake with oil bags, who still bothers to dig a little bit?

Yuan Tiangang slapped his forehead and said with some annoyance: "Thank you for reminding me that I thought things were too complicated." We are still building roads and testing steam engines to improve their efficiency and capacity. ”

The operation process of the steam engine will certainly encounter a lot of problems, and solving the problem is also the process of accumulating skills.

As soon as Du Che rolled his eyes, he lowered his head and drank tea, and after upgrading the charcoal steam engine, after the production was transferred to the Shaofu and the Ministry of Industry, he and Xiao Shiyi could continue to study the oil steam engine, at most it would take half a year to waste, and there was no hurry.

"Changshi, do you think this kind of small lightning object has application value?" Xiao Ruoyuan saluted Li Jing and asked softly. The prince likes to make money, and if it can be used for the people, it is good to make a small amount of money.

Li Jing pointed to the glass lamp and said with a smile: "It can be made into a silver and gold shell, sold to the family, and climbed the mountain to admire the moon at night, which is more elegant than a lantern." Make another batch of bamboo tubes and sell them to envoys and merchants from various countries, and earn a small amount of money, which will not be less than a large piece of glass. ”

After a change of voice, he added: "Find a way to make it waterproof, and you can use it for marching at night to catch people, or for sentry sentry, but you must pay attention to the difference between durability and selling to others." ”

"Pharmacist Li, if you want to say that it's black or you're black!" After listening to Li Jing's words, Yuan Tiangang understood what he meant. Small objects have a time limit, once they use it, find that it is much more convenient than the lantern, they will buy small objects without listening...... "need to take a nice and easy to remember name, but also do a good job of anti-disassembly design, so as not to be disassembled, resulting in unnecessary danger, harm others and themselves." ”

Liu Bu, Du Che and Xiao Ruoyuan drank tea silently: "......"

You're obviously darker, and you won't be allowed to demolish it!

The summer melon poured out the tea in the pot, re-washed the pot, took the tea, and warmed the pot...... Tea: The prince said that the green tea leaves are tender, and the two brews are the best, and the aroma is lost if there are more. However, Ge Siyao proposed that tea leaves can be fermented, and Bailu and Dongguo are experimenting with how to make fermented tea, ready to surprise the prince.

Liu Bu took two juniors and disciples...... Although Xiao Ruoyuan has never admitted that the master is his master, the fact is that the master... How does it feel very similar to the relationship between Yuan Gong and Sun Gong? Shaking their heads, shaking off the thoughts they shouldn't have, the three of them started a new round of calculations and calculations, and they also had to go to the workshop to do experiments, and after the experiments, they needed to re-check, calculate, calculate and retest...... Without a few twists and turns, it is impossible to get the data combination in the mouth.

"I'll start making a sand table tomorrow." Li Jing picked up the teacup and said leisurely.

Yuan Tiangang: "......"
