The monarchs and ministers enjoyed themselves until midnight, when Li Zhihe, Gao Shao, Yun Puzi, Feng Yi, Kong Xirong and others were slightly drunk, dismissed from Shangyang Yuan, and returned to their residences.

The old city of Luoyang, including Shangyang Garden, where Han Qian lived daily and acted in charge of military and political affairs, was located on the south bank of the Luohe River, but Luoyang was used as the national capital, and the old city on the south bank was long inadequate.

The finances were a little more generous, so Han Qian squeezed out the money and grain from the military funds and used it for the construction of the new city.

At present, in addition to the Luoyang National Comprehensive College, which was built on the north bank, the new city mainly relies on the old city along the south bank of the Luohe River and extends to the east and west.

Relying on the relatively complete public facilities of the old city and the post road system connected with Heluo County, the construction cost of extending the new city to the two wings is the lowest.

The mansion arranged for Li Zhihe by the General Affairs Department of the General Staff Office is located outside Huayang Gate, which is a newly built residential area for officials of all sizes in the General Staff Office.

Su Hongyu and her young son were going to leave earlier, but they rushed directly to Mianchi to wait for Li Zhihe, they arrived in Luoyang together at dusk today, and when they arrived at the new mansion, they took a breath of rest, left their bags and entourage, and hurried to Shangyang Yuan for a banquet.

However, Li Jin, who is just over 20 years old, enrolled in Luoyang Comprehensive College three years ago and has been living in Luoyang, and he is directly involved in the layout of the new house and personnel arrangements.

Luoyang strictly prohibits the keeping of slaves and private soldiers, Li Zhihe enjoys the deputy minister-level attendant, the security department will arrange special security forces to protect the personal safety of him and his family, and the staff office will also arrange special attendants and servants to take care of daily trivial affairs.

Han Qian had no intention of using this method to monitor the central generals, whether it was the guards or the attendants, they were all selected and recommended by Li Zhihe himself.

The manpower he is used to around him can continue to be used by his side, but he needs to go to the security department and the general affairs department to complete the entry procedures and complete the transformation from a private official to a public official.

Li Zhihe didn't care about these either.

The long street was paved with cinders, and the wheels rattled, and there was nothing new, but he looked at the bright lampposts along the street with interest, which made the night sè on the long street no longer so dark, and also made the cars and horses on the long street no longer need to pick up lanterns to travel at night.

Although Li Zhihe observed that only Shangyangyuan and the main street they passed through had new street lights installed, the main street runs through the entire Luoyang City, about ten miles long from east to west, and it is said that four or five hundred street lights need to be installed along the street to illuminate the entire long street.

Lamps and candles seem sparse and ordinary to Ding cannibals, but they are still luxurious to ordinary people.

In the heyday of the previous dynasty, there were only a few major festivals when the scene of colorful lights running through the long street was presented.

Usually, it is only the rich and noble families or the top restaurants and brothels that the courtyard at night will be lit with lanterns.

It was also a rare highlight of a bustling city after it fell into darkness at night.

Li Zhihe also thought that there had been frequent wars in recent years, and most of the money, grain and materials had to be squeezed out as much as possible to meet the needs of the war, but he did not expect that the construction of Luoyang was not as lagging behind as he imagined.

"How much lamp oil do you have to consume this night?" Li Zhihe asked with emotion.

"Ha, my father should have lived in Luoyang a long time ago, this is a coal and stone lamp," Li Zhen said with a smile, "This thing is made of limestone and coal, and the price is only one-fifth of the oil candle, and it will be stable when placed in water."

Certain-stone gas is lit and illuminated, but it is much brighter than a lamp or candle. The only problem with coal and stone is that it should be stored absolutely dry, not suitable for indoor use, but extremely convenient outdoors - this year several main streets in the city should be equipped with such street lights......"

In the past, the Liangzhou army could not be regarded as the central descendants, even if they did not hesitate to provide the most sophisticated combat weapons, but some of the main combat brigades did not have the latest technology and secrets to promote, and it was impossible to take the initiative to leak them to the people of Liangzhou.

At present, Li Zhihe's understanding of the new learning system is not even as good as his eldest son Li Zhi, who has studied in Luoyang for more than a year, let alone the second son Li Jin, who has quietly entered Luoyang Comprehensive College to study new learning.

In the past, according to the regulations of the college, in order to prevent the loss and leakage of secrets, Li Zhen could not mention his studies in the letter sent to Liangzhou, but at this time, he was chattering endlessly.

Li Zhihe originally out of suspicion, in addition to making Li Tan enter the military academy for further study, specially made the second son Li Tan elective to study instrument engineering, he also longed in his heart that one day the world can return to peace, the second son Li Tan does not need to enter the battlefield to charge, but can do something beneficial to the people's livelihood.

He originally thought that Li Qian would be resistant in his heart, but he didn't want Li Jin to mention that the engineer group he participated in at this time was undertaking a clock manufacturing task directly assigned by Han Qian.

"What else can count the time of the day besides sundials, hourglasses, astrology, etc.?" Li Zhihe asked curiously.

Li Jin took off a jade pendant tied to the ribbon from his waist, grabbed one end of the ribbon, tossed the jade pendant and swung it, and said: "The length of the tie is fixed, and the time for the jade pendant to swing is fixed, and it has nothing to do with the amplitude of the swing. The clock we are currently making uses a specific pendulum, and every time it swings, it turns a charged reed to drive the small hand to go a square; The big and small hands are connected by gears, and finally the big hands complete a full circle for 12 hours a day! It's just that the clock we tried to make, a day down, the deviation is still almost a moment, but the deviation required by the king shall not exceed one fifteenth of a quarter, that is, the so-called one minute of the king, there are still many things to be improved......"

Hourglass and missing carving are not strange things, listening to Li Jin, the truth does not seem to be so profound, but Li Zhihe did not see how complex the structure of the physical object is, it is difficult to understand how the clock can deviate from no more than one moment a day, and Han Qian is not satisfied with this?

And took the jade pendant, sat in the car and watched it swing with the naked eye, it seemed that the time of swinging once was really related to the length of the lacing, and had nothing to do with the amplitude of the swing, which was very different from his natural imagination, and he didn't know what kind of profound truth it contained.

"This is caused by the geocentric force that all things are subjected to," the carriage moved slowly, and Li Jinfei said with a smile, "My father came to Luoyang two months late, and two months later, the Chongxue Hall of the college was erected and the inauguration ceremony was held, and the monarch, the princess, and the concubine were all present in person. In order to celebrate the establishment of the Chongxue Pavilion, Yun and Princess also deliberately held two ornamental experiments, one was to drop two iron balls with a difference of ten times in weight from the eaves of the Chongxue Pavilion. The king and the second concubine have made bets, father, guess what bets you have bet......"

"I don't know what the truth is for my father, but according to my father's thoughts, most of them must think that the heavy ball will touch the ground first, and the king will definitely do the opposite." Li Zhihe said.

"My father was wrong, so the king bet on the heavy ball to touch the ground first, and the two concubines bet on two balls to land on the ground at the same time, so that those who want to follow the trend are dumbfounded." Li Jin said.

"So, Naken

It must have landed at the same time. Li Zhihe said.

"If my father arrives in Luoyang early, it would be a good bet on it, but countless people on the spot were put together by the king, and they were bitter," Li Ji said with a smile, "But everyone won't think about it, many principles of gravity are all put forward by the king, how can the king tell everyone an obvious answer?" ”

"What's another viewing experiment?" Li Zhihe saw that Li Qian was full of admiration for Han Qian, and asked with a smile.

"In Luoyang City, the vast majority of people don't believe that the breath we usually inhale and exhale is extremely stressful," Li Jin said, "Yun and Princess Yun took out two half-copper balls that could be separated and closed, and after closing, the air in the copper balls was drained, and with ten gold as a reward, they invited Jianyong from the king's guard Mali to pull the two half-copper balls apart - does my father think someone will get this bounty?" ”

"Looking at you like this, you can guess that no one has gotten the bounty." Li Zhihe said with a smile.

Watching Li Jinmei Fei talk about his contact with various new studies in the academy in recent years, he couldn't help but sigh why Chen Jitang and other figures would give up their positions of power above 10,000 people, and be willing to stay in East Lake to preside over Liyang Comprehensive College and be obsessed with new learning.

At this time, the shortage of the girder is no longer war materials, nor is it a method of engineering that is ahead of the times, but a shortage of people.

After all, when Han Qian was based in Xuzhou, the number of people under his jurisdiction only exceeded 200,000 for several years; According to Huaixi, by the first year of Taihe, the population barely reached 17.8 million; After that, Chan succeeded to the position of the lord of the Great Liang State, stabilized the situation in Heluo, recovered Xingyang, won the great victory of Yiguan and recovered Guanzhong, and the total population increased rapidly step by step, and crossed the threshold of 10 million.

In the past, even if there was no shortage of materials, Li Zhihe would suggest that Guanzhong had just been recovered, and after two years, the foundation of Guanzhong's rule would be stabilized, and then a new round of offensive would be launched against Jinnan.

However, the so-called lack of people in the beam is also relative.

After years of war in Guanzhong, the local forces would be shattered, but Luoyang was able to completely ignore the support of the local forces and directly send hundreds of officials, supplemented by the secretaries who were lurking in the early stage, as well as some retired warriors and veterans in the army, to build the local structure of the provinces, prefectures, counties and townships.

When it comes to talents in engineering and new learning, Daliang's accumulation over the years, not to mention the level, is just the number that Chushumeng and other national forces can't catch up.

When I returned to my new home, I saw Su Hongyu sending Chun Shisanniang to board a carriage, and said with a smile: "After a few years of separation, you can also finish chatting?" ”

"If it weren't for the fact that you and Hongyu were reunited after a long absence, I would have pulled Hongyu out of Yunchun Wine Workshop to talk at night." Chun Thirteen Niang said, and asked Li Zhihe to visit Lu Qingxia and Zhou Yuan in prison, and she also wanted to go over to meet together.

"In two days, or maybe you and Hongyu will go to see Mrs. and Xishui first and persuade them?"

The war against Jinnan has entered the preparatory stage, Gao Shao and Han Yuanqi are going to Xuzhou and Donghu to take up their posts, and they don't know when Tiancheng will be able to arrive in Luoyang, Jing Hao is recuperating from illness, and the staff office can only be supported by him first, and many affairs have to be taken over with Gao Shao and Han Yuanqi.

He also had to seize the time to pay a visit to Feng Yi, Guo Rong, Gu Qian, Zhou Daoyuan, Han Daoming, Zhu Juezhong, Yuan Guowei, Chen Youzhen, and other important ministers of the DPRK and the central government, and straighten out the relationship between the General Staff Office and the Left and Right Internal History Offices, the Supervision Office, and the Parliamentary Yuan.
