Looking at Yang Qinfang and Yin Mingyue looking at the two telescopes non-stop, Yang Tong couldn't help laughing, for the two of them, the telescope is an unimaginable treasure, but when it comes to Yang Tong, it is just to push a handful under the appropriate circumstances, since the glass can be mass-produced, it is just a casual thing to polish the convex lens and concave lens, the reason why the Sui people can't think of using glass like this is mainly because human minds are limited by insight and have not been liberated, and they will only passively accept new things. Instead of exerting the subjective initiative of human beings, to dig out and analyze the cause and effect. In the case of printing, people use seals every day, but they don't think about printing books in this way.

After looking back carefully, Yang Tong found that he had done a lot of things, such as glass, ploughs, paper, books, printing, ink, and refined salt...... There is also castration pig breeding, which can make cheap and delicious pork enter thousands of households, replenish the energy required by the human body, and the widespread appearance of pork makes the people of Dasui more robust, and the children born are more resistant, and the population is larger, and the increase in population has also laid a solid foundation for the future development of Jiangnan, Lingnan, and the territory outside the field. As for cement, it is also in the research of Kaitianyuan, and if this thing appears, it will be a leap forward for this era.

After combing it out like this, Yang Tong found that he had unconsciously artificially promoted the development of science and technology and society, and many things had developed by leaps and bounds. This is not something he wants to consider, just because he only has a few decades to live, and he is also an emperor, there are too many things to consider, he Yang Tong has not been idle enough to soak in the Ministry of Industry and the Open Heaven Courtyard every day, the only thing he can do is to leave a seed and guide the pioneering thinking of skilled craftsmen, thinking that the predecessors dare not think and will not think. As for how far it can develop in the future, it depends on how future generations do it.

At present, most of these items are sold by the supply and marketing cooperatives, and brought to the Western Regions, Turkic, Goguryeo and other countries by the Ministry of Commerce belonging to the royal family, so as to achieve the purpose of extracting the wealth of various countries for the use of the Sui, but Yang Tong knows that the supply and marketing cooperatives will sooner or later be replaced by the free economy, with the prosperity of commerce in the future, there will be more and more problems, and the supporting legal system will gradually keep up, but at that time, the role of the imperial court is to monitor, regulate prices, control product quality issues, products can be free of hands, just because the imperial court is always a manager, not a participant in the commercial game, even if there is a rise of big businessmen in the future, Yang Tong will never allow any line, there is a comprehensive monopoly, but this is something to be considered after the unification of the world, at present, Yang Dong needs these things to bring a steady stream of wealth for himself, to achieve the purpose of strengthening the country and making the people rich.

In terms of agriculture in the Great Sui, with the input of a large number of cattle and horses, there is no need for Yang Tong to promote it again, because the Ministry of Industry has learned to take the initiative to study and improve various agricultural tools after tasting the sweetness, which is the release of ideas, and Yang Tong is happy to see it.

In many cases, I want to distinguish between the Kaitian Academy, which is in charge of the sky, and there are those who specialize in the study of agricultural tools and those that specialize in the direction of weapons and equipment...... Although in the end, it still can't break the shackles of the times, and it is still a cold weapon combat mode, but if the Open Heaven Courtyard can make the bow and arrow string more labor-saving, the range is longer, the weapon is sharper, and the armor is stronger, it is already an overall improvement.

Then we also divided the direction of people's livelihood and designed some exquisite and practical items, such as tables and chairs that have already appeared, which are very practical, more comfortable and healthy than kneeling. Such a distinction will be gradually enriched with the further development of Kaitian Academy's research, further enriching the needs of the people.

In Yang Tong's plan, in addition to military things, after the technology of people's livelihood comes out, it will not be too secretive, after all, in terms of the imperial court, these daily technologies can benefit the people, and what the imperial court has to do is to regulate prices and taxes.

These technologies are all researched by the imperial court for the main body, and the more industries you earn in the future, the more taxes you need to pay, which is also a means to limit the expansion of wealthy businessmen, which is considered to be the most primitive means, but it is enough for this era.

When he saw that Yang Qinfang and Yin Mingyue had evolved from looking aimlessly to aiming in the same direction and starting to gossip, Yang Tong shook his head disdainfully. When he was in college, there was a high-definition telescope in his dormitory, and at night in the summer, even the classmates from the dormitory next door also came to the dormitory building of the School of Music and Dance dozens of meters away, rushing to watch the girls dance and play underwear shows.

After telling the two to keep it a secret, Yang Tong left the Qianyang Palace. It wasn't long before the big war came, and he still had too much to deal with.

When he arrived at the Xuanzheng Palace, the Chinese military forces of the dynasty were already in a state of economic strength, and the county guards and various generals were impressively listed, and the hall was arguing at this time. What they are talking about today is not anything else, but who to fight this year? And how to fight?

The Great Sui Dynasty had sharpened its knives and was ready to defeat all the enemies in one go, but the direct guide still waved westward, which became a topic of endless contention. First of all, Li Mi in the south, who has ascended the throne as the emperor on the first day of the Lunar New Year, is the same as Li Yuan at the beginning, he not only sealed the vassals, but also sent various national dukes, founding county dukes, founding county dukes, founding county princes, founding county men, founding county men, and founding county men to the Jiangnan Shen family, Wang family, Xie family, Lu family, Gu family, etc. Naturally, he tied all these people to the chariot of Wei and forced them to share the glory and disgrace with Wei State, Li Mi is now spreading all kinds of official positions and titles to the world, purely to tell Yang Tong that these Jiangnan scholars are already the courtiers of Wei, you just have to kill them. was engaged in such a conspiracy by Li Mi, and these Jiangnan families couldn't admit it if they wanted to.

At the same time, he also counted the population, and the main object of investigation was the northerners who fled to Jiangnan to escape the war, these people were one of Li Mi's important sources of soldiers, and some families had no choice but to give their servants to Li Mi, they were afraid that after the arrival of the Sui army, they would use Li Mi's edict to slaughter themselves. They don't want to die now, so they can only work with Li Mi, if Li Mi wins, maybe he can really become the founder of the country.

Externally, Li Mi also made a big move, secretly allied with Li Tang to unite against the Sui, and at the same time, recruited Meng Haigong, who was subservient to him, to lead his troops north, but Meng Haigong was afraid that he would fall into the tiger's mouth, so he repeatedly prevaricated the Wei envoy on the grounds of illness, and refused to enter the river to meet Li Mi. Li Mi was furious and ordered the army to go out to fight, although he was stopped by the ministers, Li Mi was particularly angry, and sent someone to see if Meng Haigong was really sick or fake.

Meng Haigong was afraid that Li Mi would confiscate the military power, and then unload the mill and kill the donkey; Second, he was afraid that Li Mi in front of him would be annihilated by the Sui Dynasty, causing him to withstand the attack of the Great Sui; Third, he didn't want to fight with Li Mi, so he had to continue to pretend to be sick, anyway, all kinds of prevarication...... But Li Mi was not a fool on the one hand, and on the other hand, he was also afraid that when he was at war with the Sui Dynasty, Meng Haigong stabbed him in the back, and in anger, he really sent troops forward, intending to annihilate Meng Haigong, a 'chaotic minister and thief', with the power of thunder, Meng Haigong was unwilling to sit still, and also sent troops to confront the Wei army, and the two sides were very imminent......

Upon receiving this news, the Great Sui government and the opposition were ecstatic, and some people thought that the Great Sui should take advantage of the civil strife in the south to send troops, and took Li Mi and Meng Haigong in one go. As for Li Tang, he was in a time of poverty and turmoil, and his national strength was extremely weak, so he only needed to send a partial division to harass him, and when the Great Sui annihilated Li Mi and Meng Haigong and unified the south, Li Tang could be wiped out with a snap of his fingers.

The military led by Li Jing unanimously agreed to take advantage of his illness to kill him, first the west and then the south, and after killing Li Yuan, they would send troops to Li Mi and Lin Shihong from the west and north, while Meng Haigong and Feng Ang would stay until the end.

This proposition is supported by many officials. They believed that the Great Sui had enriched the border defenses of Hexi, Guanzhong, and Jingzhou, and that five or six of the eleventh armies of the Great Sui were used to defend Li Tang, and that the deployment of soldiers and horses, the training of soldiers and soldiers, and the supply of grain and grass were all prepared for the annihilation of Li Tang. Now that Li Tang is weak, it is the opportunity of the Great Sui, and it should not be hastily changed, the key is that Li Tang has never been a peaceful character, if it is given a chance to breathe, when the Great Sui attacks Li Mi and Lin Shihong, it suddenly attacks Nanyang and Nanjun, what should it do?

Seeing that the ministers were arguing and fighting, Yang Tong shook his head speechlessly, this year's decision to focus on Li Mi, Lin Shihong, Meng Haigong, and Feng Angzhi was the result of his and the important ministers' resolutions, and the reason why he put on a posture of destroying Li Yuan was to achieve strategic deception, and the fewer people in this kind of thing, the better. However, seeing that everyone is so energetic, Yang Tong did not stop it, it is best to let them continue to argue, and when all kinds of reasons are spread, Li Mi will be more convinced that Da Sui will fight Li Yuan, maybe he will really fight with Meng Haigong, in this way, it will provide all kinds of convenience for the next war, and it would be better if the two of them lost both.

After a quarrel to no avail, Li Jing, the secretary of the military department who was pushed out by Yang Tong as a 'nursery', raised his dry voice and roared loudly: "Li Mi can fight at any time, but Li Yuan is not like this, if he loses Jingxiang, he has Bashu as the base, and Bashu is surrounded by high mountains, and in it, there are convenient water and land transportation, fertile land, no drought and flood hunger, in Zhuge Kongming's words, it is 'Yizhou Pass, fertile fields, and the land of abundance'." Such a place with the danger of mountains and rivers outside, and the accumulation of heaven inside, only a few places can be passed, as long as a few passes are held, it is difficult for our army to attack and enter, if our army is stalemate here, not only Li Yuan retreats and develops, but Li Mi can also take the opportunity to unify the south, Li Yuan is now under his rule to make the heavens angry and resentful, do not take this opportunity to destroy the pseudo-Tang, do you really want to wait for him to catch his breath and calmly deploy defense in Bashu? ”

I have to say that Li Yuan did not stop in the past few days after the New Year, first rectifying the military system, and then recovering a lot of royal land, disposing of a group of local heroes with a bad reputation, and distributing these fields to meritorious soldiers, and the effect of these measures was good. At the same time, he also took Xiangyang as the center, collected all the land and property of Buddhism into the treasury, and then distributed the oily monks to various armies, which also caused Li Tang a lot of turmoil... Li Yuan knew that he didn't have much time left, so all his reform measures were very aggressive, which caused strong dissatisfaction among the Buddhists and local tycoons.

At first glance, what Li Yuan did was almost no different from Yang Tong, but Yang Tong was carrying out radical reforms at home while eliminating external troubles, but Li Yuan couldn't do it now, there was very little national strength and time for him to use, and his constraints were too many, with the strength of the Li Tang court and his personal prestige, it was difficult to help him go hand in hand with the Great Sui, so the turmoil naturally began... Although Li Jing is a 'nursery', his advocacy of 'taking advantage of his illness to kill him' is not vexatious, but really operational, and all of them are supported by most people.

Wei Zheng said: "Li Shangshu's words are bad, not to mention that Li Yuan's water control defense line is very serious against my Great Sui, there are heavy troops in the border counties such as Chungling, Xiangyang, Fangling, Xicheng, etc., which are difficult to capture for a while, and Li Shangshu also said that the road to Bashu is difficult and dangerous, the mountains are difficult to cross, easy to defend and difficult to attack, if the war is stalemate, our army is trapped around Bashu, and it will be difficult to turn back at that time, if Li Mi unifies the south at this time, Lin Shihong, Meng Haigong and other forces are twisted into a rope, the northern expedition to the Central Plains, and the west to Jingxiang, do we really want to fight on two fronts? In my opinion, the puppet Tang is now too busy to take care of himself, and he can't spare the energy to support Li Mi, Lin Shihong and others, so we should concentrate our strength, annihilate them, and finally calmly clean up Li Yuan, who is in danger of being in danger. ”

"Wei Shangshu's words are wrong!" Li Jing retorted: "Occupying a place is not as simple as you think, whether the local scholars accept it, whether the people support it, whether the officials are loyal, and how to solve the problem of army food are all big problems. No. Didn't it end up in a complete defeat? There is also the Jingxiang region attached to Xiao Envoy's ministers, and my Great Sui is currently only occupying the territory, but in terms of people's hearts, they have not yet been truly controlled, and if there is no two or three years of hard work, it is difficult to achieve the great unification of people's hearts. There are also the people in the Central Plains area east of the Tiger Pass, who actually agree with Wagang, if the Wagang army is still there, we will definitely not be as easy as before. ”

Wei Zheng pondered for a moment and said, "So, Li Mi actually made a mistake when he left the Central Plains? ”

"Quite the opposite!" Li Jing smiled: "Although Zhai Rang is a person who is a little rich and peaceful, he is righteous, and the principle he believes in is to eat meat together, spend money together, fight local tyrants and inferior gentry, forcibly seize official warehouses, and then distribute food to poor people, so the people of the Central Plains who have been controlled by him are very supportive of the Wagang Army during the Zhai Rang period, and the strategy he implements is similar to that of my Great Sui." However, Li Mi thought that Zhai Rang had offended the local Haoqiang and the Kwantung Shi clan, and he could not become a climate, so after Zhai Rang died, he turned to the Shi clan in an all-round way, and gradually distanced himself from the people who missed Zhai Rang, resulting in him unable to stay in the Central Plains, so he could only go to the south of the Yangtze River, on the one hand, to avoid the soldiers of my Great Sui, and on the other hand, to seek the support of the southern Shi clan. But it backfired, and the southern scholars were extremely xenophobic, treating him as an invader, and felt that Li Mi was only bringing war, so there was no surname to support him before. Now, although the conspiracies are used to force the support of the southern scholars, it is not the royal road after all, and this contradiction and estrangement will break out sooner or later. Topographically speaking, the water network in the south of the Yangtze River is vertical and horizontal, and it may not be easier to fight than Bashu. In addition, Li Mi and Meng Haigong were in constant dispute and tense, but if the Great Sui soldiers arrived, they would make the two of them hate the same enemy and resist the Great Sui together, which indirectly helped Li Mi, and Li Yuan also got a chance to breathe, so the persimmon picked a soft pinch, and first hit Li Yuan, who was isolated and complaining, was the best choice. ”

"Moreover, in order to annihilate the puppet Tang Dynasty, our dynasty has been preparing for a long time, and there are grain and grass in various passes bordering the puppet Tang Dynasty, and there are many years of infiltration and operation in it, and we know all the troops stationed in various places, so we can take this opportunity to march westward, and after removing the enemy of life and death, we can follow the battle of the first emperor to destroy Chen, go down the river, and dominate the world."

Yang Tong listened to the two 'nurses' arguing, the reasons were very sufficient, and it was as if it was real, so he pretended to weigh it with a smile in his heart, and said: "It's not a way to argue like this, Li Shangshu and Wei Shangshu will each list the reasons, and discuss them one by one after Shangyuan, as for who to attack, wait for Fang Shangshu to return from the envoy." ”

"Whoa!"
