The first legitimate son of the Tang Dynasty

Chapter 262
Ang Lee returned to modern times as quickly as possible, and then bought a artificial rainfall car with money.The price of a rain-increasing and hail-proof rocket is about 10 yuan, which can complete large-scale artificial rain-enhancing, hail-proofing and other projects.

Artificial rainfall in many cities costs 2500 yuan per shot. Basically, each city needs about 6 shots and the cost is hundreds of thousands.

And there are conditions for this artificial rainfall: 1. There must be sufficient water vapor in the clouds. 2. There must be an appropriate number of condensation nuclei.

Because artificial rainfall mainly uses two catalysts: one is dry ice, which cools the surrounding air layer to tens of degrees below zero when vaporized, causing the condensation of water droplets; the other is silver iodide, which has extremely low toxicity.

Silver iodide is very efficient in making ice crystals. Usually, a cumuliform cloud can be effective only by spreading a dozen or tens of grams, and the dosage is very low, so it will not cause any pollution.

Choose the right time to use airplanes and rockets to sow catalysts such as dry ice, silver iodide, and salt powder into the clouds to cause precipitation or increase precipitation in the clouds to relieve or alleviate farmland drought, increase reservoir irrigation water or water supply capacity, or increase the amount of water for power generation.

Many people will complain why artificial rainfall is not carried out during the drought?
This is actually the biggest misunderstanding about artificial rainfall. Artificial rainfall is not a feudal superstition. If it says it rains, it will rain. In fact, artificial rainfall has prerequisites. If there are not enough water molecules in the air, no matter how many rain bombs are fired, There is no way to make the sky rain. When artificial rainfall occurs, there must be ice crystals in the cold clouds with a temperature below zero degrees Celsius. Otherwise, no matter how good the weather is and how thick the clouds are, there is no way to artificially rain. Artificial rainfall is just a boost. Means, rather than conjuring rain out of thin air.

After Li An bought back the artificial rain enhancement truck, what he was most worried about was whether he could let the artificial rain enhancement truck pass through the cave tunnel. If it couldn't pass, there would be no artificial rain enhancement. Fortunately, Li An discovered that ancient things had never been used before. The caves and tunnels will last for thousands of years, but modern things do not have such restrictions.

The artificial rain truck was brought back to Zhenguan by Li An. This time, Li An was happy, because if this happened, would he be able to carry some modern things, such as steam engines, from modern times to Zhenguan years one after another? According to the current technology of the Tang Dynasty, it is very difficult to make a steam engine, but if the steam engine is directly transferred from modern times, it will be very simple. Then slowly develop the technology, wouldn't it kill two birds with one stone?

Of course, these are all things for later. After the artificial rain-enhancing truck came back, the next day, Li An found a place suitable for increasing rain, changed six places in a row, and fired six cannons into the sky.

Then the sky was covered with dark clouds and spring thunder rolled. About half an hour later, a heavy rain came as promised. All the people around Chang'an cheered. It was really so happy.

Since then, there have been no incidents of fighting for water around Chang'an City.

In April, the first batch of high-rotating drum trucks began to be loaded up. In conjunction with the ditches and rivers, water from the river was continuously fed into the fields. The people of Chang'an finally felt at ease.

In the summer of the [-]th year of Zhenguan, the latest news came from Tuyuhun. Some Dangxiang and Xiqiang tribes were worried that they would be annexed by the Tang Dynasty, so they joined the Tuyuhun camp to resist the Tang Dynasty.

In July, the Tang army began to counterattack the Tuyuhun army. After Cheng Yaojin achieved some small victories against Fu Yun, Fu Yun used the same strategy as against Duan Zhixuan, burning the grass and escaping.

Most of Qin Qiong's subordinates believed that there was not enough forage and the expedition was a risk, and expressed their intention to withdraw their troops.

But Hou Junji objected, pointing out that this was an opportunity to destroy Tuyuhun.

Qin Qiong finally adopted Hou Junji's strategy and divided the troops into two. Qin Qiong himself, Xue Wanjun, and Niu Jinda attacked the northwest, while Hou Junji and Cheng Yaojin attacked the southwest.Both routes were successful. In only one battle, Xue Wanjun and his younger brother Xue Wanche were caught in the trap of Tuyuhun and were almost killed. Thanks to Qibi Heli's rescue, they saved their lives.

In the end, Qin Qiong learned Fu Yun's location and defeated his remaining forces, and Fu Yun was defeated.The nobles supported Murong Shun, Prince of Daning, the eldest son of Fu Yun and his wife, Princess Guanghua of the Sui Dynasty, as their leader. Murong Shun always resented that he was not appointed crown prince, so he killed King Tianzhu and surrendered to the Tang army.Fu Yun was killed by his subordinates while fleeing.

Li Shimin then decreed that Murong Shun should be appointed as the king of Xiping County and the former Lvwu Gandou Khan (Gandou Khan) to succeed Fu Yun.

This battle established the prestige of the Tang army in various tribes in the northwest, and also expanded the actual control of the Tang Dynasty's territory to the west.

But what Tang didn't expect was that after he took down Tuyuhun, another ambitious man appeared, who is Songtsan Gampo!

Just as the harmonious relationship between Tuyuhun and the Tang Dynasty was developing smoothly, Tubo emerged under the rule of Songtsen Gampo, and its northern border was directly adjacent to the southern boundary of Tuyuhun.

Tuyuhun became a battleground for Tubo to expand its borders and for the Tang Dynasty to settle down.

In the autumn of the [-]th year of Zhenguan, Songtsen Gampo led the Tibetan army to attack Songzhou in the Tang Dynasty. He ordered the envoy to deliver gold and silk, claiming to be here to welcome the princess, and said to the left and right: "If the princess doesn't come, I will go deeper."

It means that if you don’t give me the princess, I will just come and grab it myself. This is really arrogant to the point of no end.

Will Li Shimin get used to this little brat?
The answer is of course no, so Li Shimin directly dispatched Hou Junji, Shangshu of the Ministry of Civil Affairs, as the general manager of the Dangmidao march, the right-leading general Zhi Shisili as the general manager of the Bailandao march, the left Wuwei general Niu Jinda as the general manager of the Kuoshui road march, and the right general Niu Jinda as the general manager of the Kuoshui road march. The leading general Liu Lan was in charge of the Taohe River march and led [-] infantry and cavalry to attack it.

What was unexpected was that the Tang army's advance troops, under the command of Niu Jinda, directly defeated the Tibetan army before the Tang army arrived.

Songtsen Gampo was frightened and did not expect that the Tang army was so powerful, so he immediately retreated and sent envoys to apologize.

Then he knelt down to beg the princess again. Because this was the second time he knelt down to beg, Li Shimin was a good-looking person, so he agreed.

Songtsen Gampo immediately sent his Prime Minister Lu Dongzan to pay tribute and donate 5000 taels of gold. After Yu Bao did hundreds of things, he went to Chang'an City to propose marriage. At this time, Chang'an City was also in a state of turmoil, especially among the princesses and clan members. Women, they are all afraid that they will be sent to Tubo to marry.

Because in the hearts of these princesses and clan daughters, Tubo is a barbaric place where they drink the blood of Maoru. Marrying that Songtsen Gampo is simply worse than dying, so of course they will be afraid.

At one time, everyone inside and outside Chang'an City was guessing who the princess or the daughter of the clan was who was sent to the wild land, and a gambling game was actually started for a while, which was really unpleasant.
