"Your Majesty, how difficult is it to turn a desert into an oasis?" Li Jing smiled bitterly.

"General, did you say that thousands of years ago, the water of the Yellow River was also so muddy?" Li Xin pointed to the Yellow River under his feet, frowned and said: "I think thousands of years ago, the water of the Yellow River was definitely not like this, the water of the Yellow River was definitely not like this, the water washed out, brought sediment and siltation, so it made the river become the Yellow River." I want to plant more trees on the banks of the Yellow River and ban felling, and perhaps, in a thousand years, the water of the Yellow River will become clearer. The same is true in the desert, we will plant something that is easy to grow in the desert, and it will take decades, if not to turn the desert into an oasis, but at least we can make a convenient road to the Western Regions. ”

In this era, there was no cement, no asphalt, and Li Xin couldn't get it, so he could only use some of the simplest and most practical methods, that is, to plant trees, plant trees on the banks of the Yellow River, and plant some practical plants in the desert.

"Your Majesty." Before Li Jing could speak, Shang Xiufang first exclaimed. Looking at Li Xin's back in his beautiful eyes, he sighed in his heart, with such perseverance, it is no wonder that Li Xin can achieve brilliance and unify the world in just over ten years, and the things he came up with are also so shocking to the world, and ordinary people can't think of it. If so, in a few decades, there will really be a road to the West. There are patches of green on both sides of the road. I just don't know if I can see it in my lifetime.

"There is also stone paint, after the stone paint settles, there are black stones, which can be used to pave the road. Go back and let the people of Gewu Academy experiment. Li Xin thought of oil, he only knew that the asphalt that used to pave the road was refined from petroleum, but he didn't know the principle.

"Yes." Li Jing also showed hesitation.

"There are some things that you can try to do as long as you can think of them. My generation can't, maybe another generation can? Li Xin patted Li Jing on the shoulder and said, "Only by doing can there be hope, just like I did at the beginning, no one would have thought of it." I would one day become emperor, even I didn't think of it. But I tried to do it, and so I became emperor in the end. ”

"The old minister understands." Li Jinghu's eyes widened, and he nodded and said.

"Let's go! Brother Jing, I'm about to go ashore. Li Xin said with a smile: "After this battle, I can just rest for a year or two, Brother Jing, but I have to recuperate." When the time is right, you and I will go out of the Central Plains together and attack the Turks. ”

"Listen to Your Majesty." Li Jing laughed.

Shang Xiufang behind him looked at Li Xin with strange eyes. This young man is high, but he treats his courtiers like this, even if he treats himself as an ordinary person, he doesn't have a little shelf, Shang Xiufang shook his head compared to the men he had seen, maybe only such a man can make such a great achievement.

Li Xin didn't know what Shang Xiufang was thinking, and he didn't know that on the grassland thousands of miles away from him at this moment, his enemies had been united. When Yuangai Suwen arrived at Yuguan, he looked at the tall Yuguan and knew that this was not something he could overcome. But in the face of the covetousness of the Central Plains, he did not hesitate to find another person.

Jieli Khan also had ambitions for the Central Plains, and after the defeat, he was unwilling. When Yuangai Suwen arrived, he received Yuangai Suwen with a grand etiquette, and it was very soon. After some conversation, the two sides signed an alliance under the verification of the sky, and the two sides decided to launch an attack on the Tang Dynasty, a defensive line within 500 miles west of Yuguan, which was left to the Goguryeo to gallop, and the Turks would also send troops and horses to attack the long border of the Tang Dynasty. For a while, there was smoke on the border of the Tang Dynasty, and it seemed that there were loopholes everywhere.

When Li Xin arrived in Luoyang, a snowflake-like emergency document appeared in front of Li Xin, although the losses in various places were relatively small, but there were too many places, and the losses caused were great.

"Damn, damn. I will slaughter all his people. The abominable Goguryeo. Li Xin looked at the emergency document in front of him, and said coldly: "Projectile small country, is this provoking the majesty of my Tang Dynasty?" It's humiliating. Li Xin slapped the imperial case in front of him, and the hall was calm, and the civil and military generals who accompanied the army showed anger on their faces.

"Your Majesty, the army has just returned from fighting and needs to recuperate." General Li Jing still spoke.

"General, are you just letting these beasts crisscross the land of my Central Plains, watching our Datang being snatched and killed by the other party?" Li Xin said coldly.

"At the very least, there is nothing we can do about it in the short term." Li Jing said very calmly: "The best way at the moment is to clear the wilderness, give up the territory outside the city, and let the people retreat into the interior." We will not give the enemy a single piece of food, and our army will take the opportunity to fight with it. Goguryeo is a small country, its strength cannot be compared with the Tang Dynasty at all, after a long time, they must not be our opponents, we can drag them to death. ”

"The general means that a large-scale decisive battle cannot happen, but a small-scale war can still be fought?" Hum Jing said: "Your Majesty, if this is the case, there can still be the effect of training, the elite soldiers are not trained, but fought, the minister also agrees with the general's point of view, the people are strong and clear, the army is waiting for the opportunity to launch a counterattack, not seeking to annihilate the large army, but every time as long as a hundred people are eliminated, the enemy will be reduced by a hundred people, for a long time, let alone Goguryeo, even the Turks can not withstand such a blow." ”

"Good." Li Xin nodded and said: "Decree, Feng Qin Qiong is the head of the march of Yanshan Road, leading 100,000 troops, sitting in Yuguan, Feng Su Dingfang is the head of the march of Taiyuan Road, leading 100,000 troops, sitting in Dingxiang, Luo Shixin is the head of the march of Hebei Road, leading 100,000 troops, sitting in Zhuo County." Remember, you are not fighting the whole army of the enemy, but in order to constantly weaken the enemy's strength, kill one of the opponents, and the other side will be one less. ”

"Yes." Luo Shixin and Su Dingfang hurriedly responded.

"For two years, you have supported me for two years, and after two years, I will definitely personally mention the royal division and go north to the grassland. Destroyed the Turks and Goguryeo. Let them see how powerful the Datang Iron Horse is. Li Xin said viciously. Li Xin's eyes were sprayed with anger, he must let the Goguryeo people know that there are some things that cannot be done, and the Goguryeo wolf ambition really thinks that the Tang Dynasty is the Great Sui, and the land of the Central Plains is at his mercy.

If it weren't for the long-term peace and stability of the Tang Dynasty, I'm afraid that Li Xin would have raised an army to attack Goguryeo a long time ago, where would it be so troublesome. (To be continued.) )
