Li Qi finally breathed a sigh of relief, and after his first battle, he finally temporarily solved the biggest threat to the Central Plains Empire.

It will not take ten years to immigrate and settle the army, and now because of the Khitan raids, the sparsely populated Youzhou and Lulong places will become prosperous again.

After this battle, unless there is a particularly serious situation, he is not ready to go to the front line in person, and he will go to the army in person.

The world is initially stable, or honestly nest in Jinyang, take the students to study the knowledge, invent and create on the hour, and live with peace of mind with the wife and children on the hot kang.

In this world, Meng Zhixiang did not have a chance to become the emperor, and did not die of a stroke in June of the eighth year of the Republic as in the original history. According to the intelligence, this guy's body is still very healthy, and Li Qi thinks that history has changed dramatically, and he may really have a few more years.

Who knew that just in March, Li Qi had not yet returned to Jinyang, and received an urgent report from Shuzhong: Dongchuan Jiedu made Meng Zhixiang die of wind disease.

After the court report came, Li Qi sent Li Huan as a special envoy of the imperial court to Chengdu to mourn, and at the same time readjusted the officials in Shu and changed the two rivers to Sichuan: Meng Yifan was the envoy of the Xichuan Festival and was stationed in Chengdu; Dong Zhang is the envoy of the Dongchuan Festival, stationed in Yuzhou; Li Renhan was promoted to the envoy of the Nanchuan Festival and stationed in Luzhou; Li Yanwei is the envoy of the Beichuan Festival, stationed in Jielizhou.

At the same time, the right to appoint and dismiss the envoys of the four roads of Sichuan and Gorge was deprived, and the appointment and dismissal of officials in the prefectures and counties of Shu must be approved by the imperial court and confirmed by an official document issued by the Ministry of Officials.

These measures basically solved the original state of separation between the two knots of Shudi.

After driving the Khitans north of Yanshan, the imperial court now freed a large part of the mobile forces that had been used to deal with the Khitan threat. Now whoever has the ability will rebel and openly confront the imperial court!

……

The team led by He Quan, Liu Jiang and others finally succeeded in developing the world's first steam engine.

After Li Qi returned to Jinyang, he heard the good news and rushed to the research institute located in Jinyang Beiyuan, on the north side of Jinshui, to inspect the situation as soon as possible.

After the tech tree was opened in advance, its direction was a bit peculiar.

In another world, after the invention of the steam engine, it was first used in mines and factories to drive pumps and blowers, while in this world, it was placed in workshops to drive machines.

The blower has been invented, but the centrifugal pumping machine Li Qi has forgotten to tell.

Due to Li Qi's guidance, the development of the steam engine also jumped directly from the original single-cylinder to the multi-cylinder multi-expansion type.

He Quan, Liu Jiang and Wang Yuan each led a research team, and they soon found that the four-cylinder three-expansion steam engine had the highest thermal efficiency, and if the number of cylinders was increased, it could only increase the smoothness of the steam engine, but the work efficiency of the steam engine was decreasing.

All three teams were working to miniaturize the steam engine as much as possible, intending to fit it into a horse-drawn carriage, which was clearly more difficult than the current level of metalworking technology.

"Why don't you want to put it on the ship and use a steam engine to drive the ship?" Li Qi gave them an idea, although no one understood what the ship meant.

Inspired by Li Qi, these people quickly came up with a simple plan: a steam engine was mounted on a wooden boat and two huge paddle wheels like water turbines...... This is indeed a ship.

Li Qi was made to laugh and cry by this thing equipped with a huge paddle wheel, although it was indeed the original steamer.

Well, you have to teach them about the Archimedes propeller......

In fact, paddle steamers are more complex to build than propeller boats.

The invention of the steam engine is a great news for all the tuntian areas, especially in the tuntian area of the plains, if there is a pumping machine driven by the steam engine, there is no longer any need to worry about the low water pumping efficiency of the water wheel, and the new machine workshop is no longer limited by rivers and dams.

The problem is the output of this steam engine, He Quan and Liu Jiang gritted their teeth and reported the annual output of 200 units.

This is still a long way from real promotion and application......

In an agrarian society, the territory of a dynasty was largely limited by the problem of transportation. If this transportation problem is not solved, Li Qi believes that it is impossible to completely solve the problems of the northern grasslands, the western regions, and the south.

The mighty Mongol and Yuan empires were in fact in a state of fragmentation.

……

In May, An Yuanxin went to Jingzhou as an envoy of the imperial court.

After the change of Xingjiaomen, Jingnan Jiedu made Gao Jixing call the king self-reliant, and built the Nanping State, and then because An Congzhi sent an army to crusade, he simply betrayed the Tang Dynasty, took refuge in the Wu State, and changed to the Wu State as a vassal.

It's just that after Gao Jixing died of illness, his son Gao Congxue turned his back on Wu again, reattached to the imperial court, and was reappointed by Li Siyuan as the envoy of Jingnan Jiedu.

After Li Qi pacified Luoyang, he continued to appoint Gao Congzhi as the envoy of Jingnan Jiedu, and added the post of Taiwei of the inspection school to show his grace.

Gao Congzhi met An Yuanxin and asked, "What is the holy order of the angel to come to Jingzhou?" ”

An Yuanxin once served as the envoy of Shannan East Road, and he was in Xiangyang, so he was an old acquaintance with Gao Congzhi.

An Yuanxin said: "Lingnan Liu?? Since he became the emperor, the Son of Heaven wants to conquer Lingnan, and the imperial army wants to borrow Jingzhou and Chudi, I don't know if Taiwei agrees? ”

Gao Congxue's adviser Sun Guangxian said: "This is a false plan to defeat the enemy, but the court has a good calculation. ”

"Even so, does the gentleman want to encourage the captain to hit the stone with an egg?" An Yuanxin said, "If you are like Ziwei all over the world today, don't dare to disobey." For the sake of his own life, can Jingnan stop the imperial court from marching? I and Taiwei were originally close friends, so I asked for my life in front of the Son of Heaven and made a special trip to persuade him. ”

Gao Congzhi said: "I'm afraid that if I agree, the King of Changsha Ma may not agree." ”

An Yuanxin said: "If Ma Xifan doesn't know how to advance and retreat, I'm afraid that there will be no more Changsha Ma clan from now on." ”

After hearing this, Gao Congzhi was silent for a while and then replied: "Please also ask Angel An to return to the Son of Heaven, I am willing to go to Jinyang to recuperate." ”

"It doesn't have to be like this, before I left the court, the Son of Heaven said that if the Taiwei is willing, he can stay behind for Bianliang." An Yuanxin said.

The matter on Jingnan Gao's side was tantamount to a smooth settlement by peaceful means, but after the envoys sent by the imperial court arrived in Changsha, Ma Xifan rejected the court's request to pass through Chu and conquer the Southern Han Dynasty.

In June, Li Qi ordered Fu Yanchao to be the envoy to the south, Li Congke to be the envoy to Pingnan, An Xianke to be the envoy to Dingnan, He Fujin to be the Sima of the South Road march, and the envoy to the south. The 100,000 troops of the imperial court were stationed in Jingzhou in three ways, preparing to start the southern expedition.

This road to unifying the world is also picking up soft persimmons and pinching, and first take the king of Chu in Changsha......
