Why did the Governor of Jing'an report this? Because before the departure of the northern army, General Jing'an gave him a list of people who needed to be monitored and paid attention to: Xiao Yan and Murong Jue were listed on it.

It is very common for martial arts masters in the army to learn from each other, although the identities of Xiao Yan and Murong Jue are attention-grabbing, but they are not important enough for the Zhengbei Shuai Si to be written into the recital of the emperor, and it is not a big deal if there are no dead people.

Li Yuzhen looked at it coldly for a while, picked up the pen and approved a "read", indicating that he had read it, so he closed the chapter and put it on the pile of chapters on the right.

Putting aside the red pen, she picked up the golden dragon cup on her right hand, opened it and drank two sips, her teeth clicked, crushed a piece of walnut kernel, swallowed it coldly, her eyes could not see pain, but it was as sharp and cold as a blade.

She sneered in her heart.

Seriously injured...... It's just a serious injury.

You deserve to be beaten!

If Xiao Yan was in Chang'an, she would beat her to death!

Li Yuzhen took a sip of tea, clicked again, and crushed the golden silk jujube kernels.

Lian Cheng, who was standing in the corner, shrank into the corner again.

Your Highness, it's been terrifying lately.

Li Yuzhen bit all the eight treasures in the tea one by one, and raised his hand to drink the tea soup.

It's a pity that no matter how sweet the tea is, it can't relieve the bitterness in my heart.

Suddenly, "Ding Ding Dang—"

A cheerful music, the bird that chimes the bell jumped out of the top of the bell happily, and while spinning happily, it cried out crisply: "Saint, it is right! Ten o'clock, saint! Ding Dingdang—" With the sound of music, the bird was pulled back by the spring, but it fluttered its wings, looking reluctant, and struggled to shout, "Your Highness Wanfu Jin'an-" The sound of the word "An" echoed countless times.

Lian Cheng was expressionless, and after listening to it many times, he still wanted to laugh.

Li Yuzhen's eyebrows twitched, and he raised his hand to rub his forehead.

This bell ...... It's so lively.

In March last year, the Imperial Technical Research Institute presented a new type of mechanical clock, replacing the pendulum with a hairspring balance, which is a technical step further than the pendulum clock, and most importantly can be carried around accurately on the move – which is important, especially for the military and navigation. The Royal Academy of Arts and Arts also engraved a rune on the imperial bell of the dedication, and added a voice to tell the time, and the bird's voice and demeanor were very dignified. But just a month ago, His Majesty summoned the talisman master of the Academy of Techniques to express a small "guidance" opinion. Then the bell that the institute sent back became like this...... Active and lively. The queen also came over specially and listened to this "Wan Fu Jin An An'an", laughed very much, and said that the saint had changed well. Li Yuzhen wanted to throw the bird bell out, but ...... Parents love each other.

Thinking of his father's intentions, Li Yuzhen felt that the pain in his heart was not so painful again.

Everything will pass.

As the master said, there will always be joy and pain on the road of life.

These pains are also part of her.

Lian Cheng changed the teacup, and after a while, he put on new tea.

Li Yuzhen is already reading the next book.

This is a report submitted by the Imperial Academy of Scientific Research, with a "confidential" seal stamped on the cover, and a rune seal is used to unravel Li Yuzhen's divine thoughts, which are set by the rune master as Li Yuzhen's divine thoughts, and inside is the latest research theory reported by the Electric Energy Research Agency.

Electric energy research is one of the energy research departments of the Imperial Academy of Sciences, the establishment of the project has been 70 years, but compared with the three major topics of elemental energy, solar energy, and stellar energy, it is still a new topic, and it was originally a partial branch of the development of elemental energy - the study of lightning energy, but the research speed of electrical energy is faster than the previous three topics, the study of yin and yang electric energy, and the study of batteries, and repeatedly charged electric energy stones, the latest theory is electromagnetic induction, and according to this theory to create a generator, The possibility of hydroelectric power is currently being studied. When Li Yuzhen opened it, he was thinking, could it be that this research has achieved results? If that's the case, that's a good thing.

However, this is a research project derived from the field of electrical energy - electromagnetic waves.

Li Yuzhen suddenly had a feeling that he thought it was a watermelon but picked up a sesame seed.

This report talks about the progress made in the research of electromagnetic wave communications.

Communication is also a major subject, and "radio waves" are of course not sesame, but the most important purpose of the establishment of the Imperial Research Institute is energy, power, and new materials, and the high-end of the aim is starships and astronautics, and the research in other aspects is biased.

But this "partial branch" is also relative, in fact, these are called "inevitable and accidental discoveries in the research process" by academicians are important for the development of science and technology.

So Li Yuzhen was not disappointed, but quite interested.

"Try to replace low-end techniques with technology", this is the path set by Gaozong.

She browsed with her divine sense, and quickly read more than forty pages of the recital. Although there are many professional scientific terms in it, Li Yuzhen does not need to understand the meaning of these terms, and he can understand the main idea through the whole text. Obviously, the academician who made the report was very aware of her ability, and if she wrote it to the emperor, it would not be so complicated, but a headache on how to explain these complex theories in simple language.

But for the grandmasters who have already stepped into the door of the law, the theory of radio waves is simple, the same as the sound transmission of martial artists, they all use air vibration to transmit sound, but the wavelength of vibration is different. However, the disadvantage of air vibration transmission is also obvious, that is, it is easy to be captured. Therefore, the Grandmaster's transmission of sound with divine consciousness is to use spiritual power to oscillate, which is a higher law than air vibration. Li Yuzhen thought in his heart that this kind of radio wave communication must have the defect of easy leakage.

However, mass communications, such as official notices, do not need to be kept secret, and if we can really develop communications comparable to the speed of sound, it will be a great leap forward. At the very least, it can replace the current outdated means of communication. Li Yuzhen is extremely nostalgic for the communication of the era of magic, not to mention the speed of thousands of miles of transmission notes, he specializes in reading with his personal divine sense, and has a high degree of confidentiality.

But now, where to find the spiritual sedge containing spiritual energy to make rune paper, and the blood of demon beasts to use as rune ink? With today's rune paper and ink, the drawn transmission notes will fly out of thirty or forty miles at most before falling to the ground, and are mostly used in short-distance emergency communications. As vast as the empire's territory, 100,000 miles of communication, the fastest way to communicate is the space communication array, but the energy burned out once is activated, and no matter how rich Datang is, it can't withstand the monthly activation, and it is only used for important and urgent "national announcements", such as the announcement of Yan Zhou's issuance of war bonds before declaring war.

Li Yuzhen picked up the eight treasures tea and drank two sips, put down the teacup and yawned for a while, thinking about the value of this research in his heart. The key is the speed and cost of communication, if it can replace the long-distance eagle-carrying rune communication, it is worth the investment.

After thinking for a while, she picked up the pen and left a word after the recital: "Yes." "Agreed to their funding request.

Technical research and scientific research are all big eaters of silver.

It was still silver smashed into it, and I couldn't hear a sound for years.

Fortunately, the "two academies" have been established for more than 170 years to her, think about the time when Gaozong established the two academies, it was "one poor and two white", throwing silver can not hear the sound, the three basic disciplines only have a preliminary system of mathematics, physics and chemistry are still scattered, how is it now, each basic discipline is subdivided into seven or eight disciplines, not to mention derivation. It's really the predecessors who planted the trees and the descendants picked the fruits...... When Li Yuzhen thought about it, he felt less pain in his heart.

When people are in pain, they need to compare.

Li Yuzhen smiled bitterly.

She still hasn't put it down......

She got up and sat down on the couch, walked a few steps, put on her clogs, and went out on the verandah to get some air.

The sky is blue, like pure gemstones, and the clouds are dashing and floating, gathering and scattering.

She thought to herself: If there is love in the sky, the sky will be old.

Because of ruthlessness, genius Changchun.

If a man is ruthless, he is at ease.

……

There was the sound of footsteps in the corridor.

The summoned chamberlain came back and said closely: "Your Highness, Academician Wu and Academician Zhong have arrived. ”

The two academicians came together, because the Royal Academy of Art and the Imperial Academy of Science were in the same workshop, and one east and one west occupied the entire truth-seeking workshop, so the chamberlain was summoned together. The two academicians stepped forward, folded their big sleeves, and saluted: "See Your Highness." ”

Li Yuzhen was wearing a prince dragon robe embroidered with gold embroidered on the earth, and there was also a black jade crown on his head, he looked very solemn, raised his hand and made a gesture of invitation, and said: "The corridor is open and breathable, just talk here." ”

"Yes."

The three palace attendants moved the high Zen chair and two circle chairs, and placed them in a humble position.

Li Yuzhen said: "You sit." I sat in the room for a long time, stood for a while, stretched. ”

"Your Highness." The two academicians thanked each other and sat down.

Datang has always respected scholars, especially research scholars, the emperor has always been very courteous, and the two academicians sat down upright, without sitting shallow or hanging half of their buttocks to express awe.

On the corridor, the maids and guards stood far away.

Li Yuzhen applied a true qi barrier and said directly: "Invite the two academicians to come over, it's about the Yanzhou Crystal Mine." Shen Xianggong reported back: Oghuz did not agree to the Tang Dynasty to mine any spar mines...... so he briefly explained the situation of the negotiations, "The opinion of the ministers in the political hall is: exchange ore for ore. - But be cautious about what kind of mine to exchange. ”

The two academicians understood as soon as they heard it.

Energy research is one of the most important research subjects of the Royal Academy of Arts and the Imperial Academy of Sciences, and the ore resources obtained by the Tang Dynasty in every foreign war are in demand by the two academies. I am afraid that the two institutes know better than the people of Yan Zhou -- the most advanced mine detectors and ore detectors are made by the two institutes, and there is a special "gold captain" among the Jing'an lieutenants, that is, mine scouts. There are several kinds of energy minerals in Yanzhou that are high-grade ores that the two institutes need, and there is also a kind of energy ore whose grade reaches "special quality", which exceeds high grade, although these ores Datang has quite rich reserves, but there is no high-grade one, and the two institutes have the most say in which ores to exchange for these ores.

Academician Zhong glanced at Academician Wu and did not speak.

The Royal Academy of Arts, the Imperial Academy of Scientific Research, and the Imperial Institute of Technology are often collectively referred to as the "Three Research Institutes", but in terms of status, the Royal Academy of Art is the highest, not because it belongs to the royal family, but because it is higher than the Second Academy of Scientific Research and Technology Research in terms of law mastery and research rank, and when the academicians of the three academies are together, they are usually headed by the Academy of Arts. - Of course, Academician Zhong will not speak before Academician Wu.

Academician Wu is already seventy-six, his hair and beard are all white, but his spirit is still strong, and his eyes are dark and bright. He majored in runes, and thirty years ago he was at the level of a great rune master, although Fu Xiu did not temper himself like martial arts, and his vitality was stronger, but his body cultivation was vigorous, and he was more vigorous than ordinary people. He replied: "Just as I was about to report to His Highness, the coal-smelting conversion circle cooperated by the two academies has made a new breakthrough - the experimental report just released yesterday has reached the pure level of energy transformation. He said happily, "Your Highness, we can smelt coal spar." ”

Li Yuzhen raised his eyebrows, "Really? ”

Coal spar is coal that can be completely burned after smelting.

"Complete combustion" means that no toxic gases and exhaust gases are released, and no particulate dust is produced.

The importance of this in maintaining the purity of the atmosphere and the concentration of vitality is obvious.

Why has coal been mined for more than 100 years, but coal has not been promoted as a fuel in the private sector? It's because of the "pollution" of the vitality.

Whether it is a martial or a martial art, a cultivator must rely on the vitality in the atmosphere to cultivate, and if the vitality is thin, the cultivation path will definitely decline. Just like in ancient times and ancient times, the destruction of the prosperous cultivation civilization was not only because of the war between the three clans that caused the cultivators to fall one after another, but more importantly, the endless cultivation for hundreds of thousands of years and the uncontrolled exploitation of the spiritual vein ore by the three clans, coupled with the increasing power of the human race and the demon race, made the spiritual energy burden of this planet reach its peak, the spiritual veins were exhausted, and the consumption of spiritual energy was far less than the repair of spiritual energy, even if the war between humans, demons, and gods did not break out, at most tens of thousands of years later, this kind of civilization built on spiritual energy would also decline and be destroyed.

Don't forget the past, the teacher of the future, for the current cultivators, maintaining the concentration of vitality in this world is the most important thing. However, the earth has no spiritual veins to produce spiritual energy, and if you want to maintain the vitality energy of the world, you can only rely on the green vegetation that can give birth to weak life vitality such as forests, grasses and trees. So all countries have been mining and using coal for a long time to replace a lot of timber.

However, after using it for a period of time, it was found that there were too many impurities in the primary coal to be completely burned, producing a large amount of toxic gases and particle dust, which greatly polluted the vitality and damaged the green vegetation and soil. After discovering this hazard, countries immediately stopped using raw coal fuel, made efforts to study and apply coal smelting and purification techniques, and severely prohibited private mining, smelting and use of raw coal as fuel, and must use clean coal smelted by officialdom. But the price of this coal is too high for ordinary people to afford.

The most advanced raw coal purification technology is Datang, but it can not be completely purified, and the clean coal extracted - Datang Guanye Field is called coke, which has no toxic gas after combustion but still has a little waste gas, and the main thing is that the cost is high and the price is expensive. Not only can the common people not afford it, but even small and medium-sized workshops and workshops cannot afford it, and they have to use charcoal as fuel. The imperial court could only force the use of large factories and gave some preferential policies to factories that used coke, such as tax incentives. However, the protection of trees is only half achieved, and the use of coke also increases the cost of manufacturing products.

Li Yuzhen calmed down and asked, "What is the cost of coal spar compared to coke?" ”

Completely pure coal spar is good, but if the cost cannot be reduced, it still cannot be widely used to replace charcoal.

Academician Zhong replied: "Back to Your Highness, the refining technique is divided into two parts, one is the technical process, and the other is the magic circle. The scientific research institute has developed a new separation and conversion technology, which separates harmful substances by technical process, and then recovers and converts a part of the harmful substances. Therefore, the new technology is to increase the part of the technical process and streamline the part of the circle, so that the energy to maintain the circle only needs to be 10% of the original, and the fire energy generated by the combustion of the high-temperature furnace can be converted to completely supply the array energy. ”

In the past, the cost of purifying coal was high, and one of the important reasons was that it required a huge amount of energy to maintain the circle. It's a pain in the flesh for all countries. Therefore, magicians from all over the world are studying how to convert water energy and fire energy into array energy, but this has geographical limitations, and a large-scale energy conversion array is also a very energy-consuming project. Therefore, the cost of purification remains high.

The new technology of the scientific research institute has replaced most of the functions of the magic circle, and only the last part of the magic circle has been completed, which greatly saves energy, and the cost is naturally greatly reduced.

Li Yuzhen nodded, his cold eyes showed a little warmth, he took a few steps with his negative sleeves, turned back suddenly, and the dark dragon robe crossed a neat arc, his tone was thin and cool but powerful, and said: "Okay, this will give you a great credit!" ”

The two academicians smiled.

Li Yuzhen also instructed: "The scientific research institute should sort out the data, analyze the improved cost reduction in detail, and submit a report within seven days." The two academies should immediately form a technical reorganization and go down to the various coal coking smelting plants to renovate and apply the new smelting units -- you should go down to negotiate and write a plan for the truth. ”

"No." The two academicians replied.

Li Yuzhen smiled at the sky and said, "This achievement came at the right time." ”

The negotiations with Oghuz were exactly what they needed.

In this way, Datang does not need to pay ore.

——All valuable ores, Datang does not want to flow out at all.

Li Yuzhen's dark and indifferent eyes reflected the blue sky, like a deep valley and a quiet pool, "Oghuz and Yan Zhou, they really occupy a good place." ”

If this sentence is heard by people who don't understand, they must laugh in their hearts - a place like Oghuz and Yanzhou, except for the jungle and grassland, is a desert ice field, and there are twelve months of the year, seven or eight months are winter, what kind of good place is it?

Academician Wu and Academician Zhong nodded with affection, that place is a good place, the types of minerals and total reserves are not as rich as Datang, but they are full of high-grade ores!
