If the emperor asks about the military equipment in the customs at this time, it indicates that between the authority and the duty, the former is the first.

However, at this time, the emperor asked Xue Yantuo about military equipment, which also showed that the latter was more important between the two.

At that time, not only did there be no conflict between Xue Yantuo and the Tang Dynasty, but they were both enemies of the Eastern Turks and were actually allies of each other.

However, not long ago, Li Shimin said in public in the court, "Even if the Turkic species are all rebellious and there are no more animals, I will not attack after all." I will wait for him to fail me, and then crusade against "Yunyun, how can he not be more than ten months, and become a person who is "unbelieving, unkind, and unmartial" in his own mouth?

Therefore, although the name of the appointment here is "to prepare for Xue Yantuo", it is actually "to prepare for the Turks".

So at this time, Pharmacist Li replied: "If you want to plan Xue Yantuo's military preparation, you must first have an in-depth understanding of it. If you want to traffic Xue Yantuo, you can go out of Liangzhou to the west and Yingzhou to the east. Yingzhou is far away, and the ministers will go to the east first. ”

Li Shimin was slightly surprised: "My brother wants to go in person?" ”

"Yes." After Pharmacist Li bowed in response, he immediately said: "Shandong and Hebei were originally Dou Xia's hometowns, and after the defeat of Dou Jiande and Liu Heimin, their people will not be allowed to use them, and they will live in Luli and be troubled villagers. However, the minister thought that there were quite capable people among his generals, and if they could be used by His Majesty, they could also avoid the trouble of his countrymen. Isn't it good for one to serve the country and the other for the people? ”

After thinking about it for a while, Li Shimin knew Pharmacist Li's intentions, and said with a smile: "What my brother is referring to, but back then, Su Lie, who first took Zongcheng, and then went down to Su Lie, Xiang, Li, and Wei Zhuzhou? ”

Pharmacist Li replied: "Your Majesty Mingjian, it is Su Lie. ”

Li Shimin nodded and said, "He is indeed a rare fierce general!" ”

It was a sunny day on 2 February

Grass sprouts are born for a while

The light shirt is thin, and the horse is young in spring

The first line of the cross

Bai Juyi's song "February 2nd" is light and fresh, completely fresh and refreshing of youth.

On February 2 the river went up. The east wind is warm, and the sheng is blowing

Flowery whiskers and willow-eyed scoundrels. Purple butterflies and wasps are all affectionate

The first four sentences of Li Shangyin's poem "February 2nd" are charming and beautiful, full of the gentleness and charm of spring flowers.

February 2 has become a festival for literati and writers to go out and write poems, which is the romance after the Tang Dynasty.

However, in the mid-spring of the early Tang Dynasty, the weather was the same east wind and the sun was warm, the earth was born with the same buds, and all things were also scoundrels and affectionate.

This is the season when "the peasants tell Yu Yichun that there will be something to do in the west".

Now, above the Weishui, there is a lonely boat going downstream.

The two middle-aged scholars on the boat led each other, and the first one was calm and relaxed, but he was faintly not angry and arrogant, it was Pharmacist Li; The next one is gentle and elegant, but it is difficult to hide his arrogance, it is Lu Zesheng.

There is another team of towel cars accompanying the waterfront, and the leader of the team is a young general who is heroic, but he can't hide his innocent state, it is Xue Guwu.

He never liked Lu Zesheng's lonely and isolated habits, at this time, seeing the two of them in the boat drinking together, although he had a military order, it was inconvenient to drink, but he held an empty sword and rolled his eyes to the sky.

If the poet saw Xue Guwu at this time, he was afraid that it would be more than 100 years earlier, and he would compose the scene of "A Wu Taoyu is a beautiful young man, looking at the blue sky with white eyes".

I only heard Pharmacist Li smile and said: "Our trip is either a life towel car, or a lonely boat, it is really not only slender to find a ravine, but also rugged and through the hills." ”

Lu Zesheng responded with a smile of "yes", took a Yaoqin sideways, and stroked it casually.

Pharmacist Li listened to the rhyme of the piano and chanted along with the rhythm: "Mu Xinxin ~ to be proud, the spring trickles ~ and flows." Then he clapped his hands and praised: "High! But Mr. New Work? ”

Lu Zesheng thanked him humbly: "Don't dare!" ”

Then while continuing to play, he said: "Tao Ling's 'Return to the Future' has lofty intentions, and the servant has been thinking about it for several months, but he still can't compose the whole song. Tao Yuanming once served as Peng Zeling, so he was called "Tao Ling".

As Lu Zesheng spoke, he reinterpreted the half-song that had been composed, and played it to "or a life towel car, or a lonely boat", and the sound of the piano came to an abrupt end.

I only heard him say: "Lingjun, our lonely boat will arrive at Tongguan in the afternoon, and we will arrive in Shaanzhou tomorrow, and we will have to change to a towel car at that time." At this time, Pharmacist Li inspected the school book order, and his subordinates called him "Lingjun".

Pharmacist Li nodded and said, "Yes." This section of the water after Shaanzhou is not suitable for boating. ”

Lu Zesheng nodded and said, "Yes." After Shaanzhou, it is to the pillar and the three gates. Dayu controls the water, in this encounter the mountain mausoleum barrier, will be chiseled through the river. Then the river flows, wrapping around the mountains, and the mountains are like pillars in the water. ”

Pharmacist Li nodded and said, "Yes." Dayu before and after three chisels, three through both decisive, the water flow is divided, like three doors. ”

The names of "Pillar" and "Three Gates" are originally found in the "Water Jing Note. Volume IV. River Water", which did not have the name of "Sanmenxia" at that time.

Lu Zesheng nodded yes, and continued to quote the "Notes on the Water Classic" and said: "'From the pillar below, the five households have been up, and in the meantime, one hundred and twenty miles, the stones in the river are outstanding, and they are connected to the land...... Although its mountains are open, there are still turbulent currents, rocks and clouds, waves overflowing, there are nineteen beaches, the water flow is rapid, the momentum is the same as the Three Gorges, damaging boats and boats, and it has suffered since ancient times. This water journey is really not suitable for boating. ”

Pharmacist Li nodded and said, "Jianghuai grain can be transported to Chang'an, mostly through waterways. However, this area has to be converted to land, which is the most time-consuming and costly. ”

Lu Zesheng nodded yes again and said: "I, the Lu family, have a little experience in shipbuilding, but if you want to go up the river in the three pillars, you still can't rely on the boat alone, but you must use the fiber pull. If the ship is too heavy to carry grain upwards, it must be diverted to land. After this journey, it is transferred back to the waterway. Such a back-and-forth load is indeed the most time-consuming and time-consuming node in the whole journey. ”

After Zhenguan, the Tang Dynasty was at its peak, and the population of Guanzhong increased dramatically, causing Chang'an to lack food several times.

The digital emperors, including the Empress Wu, personally led hundreds of officials to Luoyang to eat.

The key lies in the time-consuming and time-consuming transportation of grain by land and water.

That's a later story, and that's at the time.

While the two of them were talking, the ship had arrived at Tongguan.

This visit to the east, in the name of Lu Zesheng's order to go to Panlong Mountain to build a temple, did not alarm the local government.

After spending the night in Tongguan, the group passed through Kunshan and Hangu Pass the next day, that is, to Shaanzhou.

Again the day to change to the overland, after a hundred and twenty miles to the pond.

After that, it either ordered a towel car, or a lonely boat, passing through Luoyang and Zhengzhou.

Luoyang was originally the eastern capital of Yang Sui, and its prosperity was once better than that of Chang'an, Xijing.

However, after several wars at the end of the Sui Dynasty, it had already fallen into decline and depression.

Later, it became the capital of Wang Zheng, and after Li Shimin destroyed Wang Shichong seven years ago, he ordered the destruction of the Luoyang Palace, so at this time, this place is still full of devastation.

They hurried by on their way and did not stay long.

After Zhengzhou, it turned to the north, and then went to Xiangzhou and Zhaozhou.
