The summer is scorching, the more south it is, the hotter it is, Li Zhang can't sit still in the carriage, after all, the carriage is stuffy, and there is no air conditioning, it is far less comfortable than riding on a horse, at least there will be an oncoming wind blowing away the sweat on the body, bringing a burst of coolness to himself, but the dust is also mixed with the wind, even if the face is covered with a scarf, it will still be mushy soil.

"Transportation, it's really a big problem, but if productivity can't be raised, this problem will be difficult to solve!" Li Zhang took a wet towel to wipe off the dust on his face, and then sighed.

Road hardening can solve the problem of dust, but also can solve the problem of muddy roads when it rains, he has the formula of cement, but the cost of firing this thing is a bit high, if the roads of the Great Song Dynasty are really paved with cement, I am afraid that the Great Song Dynasty will have to go bankrupt.

"It's better to get the cement out first, at least harden the roads in the city first, so that every time it rains heavily, the city will be muddy." At that moment, Li Zhang said to himself again, he didn't know how difficult it was to travel without going out, he had only been to Gyeongju as far as before, where there was a wide official road with the capital, and there were usually special people to maintain it, so it was not difficult to walk, but this time he went to Liaoguo, but he saw the difficulty of traveling, and there was even no way to go in some places.

Now Li Zhang and the others have left Hejian Mansion, and before leaving, he went to see the Qiu Governor's Mansion again and asked the other party to help take care of the Zhao family, mainly because he was afraid that the Chu family would retaliate in the future, but according to Qiu Governor's Mansion, the Chu family is now very honest, not only lost money, but also went to the Zhao family to apologize in person, which made Li Zhang feel a lot more relieved.

The things entrusted by Zhao Anren have been completed, and Li Zhang has also begun to rush at full speed, because it is not far from Qingzhi's delivery date, so he also wants to return to the capital as soon as possible, but the road is difficult, and this road is also very hard.

Originally, when he was in Hejian Mansion, Li Zhang wanted to go by boat instead, because the northernmost part of the Grand Canal is here, although the speed of river transportation seems to be a little slower, but it can also be rushed at night, only two boatmen need to rotate day and night, and the speed is faster than the land route, but it is a pity that a few days ago, the downstream of the canal was flooded, causing the water surface to drop, and many boats were blocked in the river, which made him have to give up the idea of changing to the waterway.

Half a month later, Li Zhang and they finally came to the edge of the Yellow River again, as long as they crossed the Yellow River, the front is the boundary of Kaifeng, although there is still a distance from the closure of the city, but Li Zhang can completely throw off the mission and return to Beijing as soon as possible, after all, there are too many people in the mission, and the speed is not fast, anyway, the mission of the mission has been completed, and then Fu Bi will help take care of it.

Compared with the last time the Yellow River was frozen, the Yellow River has already melted, and a long pontoon bridge has been erected on the river, and there are countless cars, horses and pedestrians waiting to cross the bridge on both sides of the bridge, after all, the carrying capacity of the pontoon bridge is limited, and there are restrictions on crossing the bridge every day, so many people may have to wait for a day or two to cross the bridge, which is almost unimaginable in later generations.

However, Li Zhang is the mission, naturally there is no need to queue, directly find the official who manages the pontoon bridge, and directly cross the pontoon bridge, but when walking on the rickety bridge deck, Li Zhang also feels empty in his heart, after all, the pontoon bridge can not be compared with the real bridge, plus the Yellow River water margin is very turbulent, so the bridge deck of the pontoon bridge is also very unstable, no wonder to limit the number of people who pass every day.

After finally crossing the pontoon bridge, it was late at this time, although Li Zhang was in a hurry to go home, but he could only rest for the night at the post station at the mouth of the Yellow River, but the next morning, he handed over all the affairs of the mission to Fu Bi, Fu Bi also knew that Li Zhang was in a hurry to go home, so he also took it very happily, and then Li Zhang took the wild dog and rushed all the way to Tokyo City.

However, when Li Zhang and they saw the tall city wall of the capital from a distance, they suddenly heard a rapid sound of horses' hooves behind them, and then saw a horse galloping, originally Li Zhang thought that something had happened to the mission, so Fu Bi sent someone to find him, but he didn't expect this person to rush away from him, and Li Zhang, who was choked by the dust, coughed.

"Hurrying soldiers." At this time, the wild dog looked at the distant back and said, his eyes were good, even if the other party flashed in front of them, he still saw the other party's outfit clearly.

The so-called urgent foot delivery, similar to the Qing Dynasty's eight-hundred-mile expedited, is mainly used to transmit military information, and it was also set up by Zhao Heng himself, because when he ascended the throne, there were battles with the Khitans from time to time, and a channel for rapid transmission of news was needed.

"He came from behind us, it should be news from the north, but I don't know if it's Hebei or Northwest?" Li Zhang looked at the smoke and dust brought up by the soldiers in front of him, and he also muttered to himself.

At that moment, Li Zhang continued to hurry, after all, the capital was already close at hand, but what he didn't expect was that just as he walked a short distance forward, suddenly there was a hurried sound of horses' hooves from the rear again, and then another hurried paved soldier galloped by, which made Li Zhang can't help but show a solemn expression, even if the hurried foothand is no longer limited to the transmission of military information, but it is rarely seen in ordinary times, but now there are two hurried foot-toes appearing, which is a little strange.

However, what Li Zhang didn't expect even more was that in the next half an hour, there were three more urgent foot deliveries in a row, and he saw five urgent foot deliveries alone, which made him even more surprised, the urgent foot delivery appeared so frequently, there must have been something major happening, which also made him speed up again and rush to the capital.

At noon, Li Zhang and the wild dog finally came to the city gate, and then rode into the city, Tokyo City is still the same, and even feels more prosperous than when they left, after all, it was winter when they left, and many people were reluctant to go out, but now it is the height of summer, although it is hot, but it is the most lively time in the capital.

However, Li Zhang was not in the mood to enjoy the scenery of the capital at this time, but hurried home, first, to see the situation of Qingweaving, and secondly, he also wanted to know what information was transmitted by the hurried hand just now?

Finally waited for Li Zhang to cross the streets to the front of the house, he did not report in advance when he came back, so when he entered the gate, the servants of the family were also surprised to greet him, and then someone reported to the inner house, and after a while, he saw the raccoon dog being the first to run out, and when he saw him, he screamed and threw himself into his arms and refused to let go.
