The northwest army was highly efficient. Under the command of the king of Zhao, the army was ready to go in less than two quarters of an hour. The king of Zhao had changed his horse and ordered to set out after making sure everything was correct.

This time, they couldn't rest all the way. They had to go all the way to Qingzhou City. Because only when they enter the city can their grain, grass and gold and silver be considered safe for the time being.

King Zhao guessed last night that Qin Jiyan sent Cheng general city to stop them here mainly for food and grass.

In order to maintain the basic life of the army and the people in the city, Qin Jiyan must have enough food and grass. Looking around, no one has more food and grass than them. Qin should not rob them.

They sacrificed their reputation and robbed them from the common people. At the beginning, he abandoned the city to take care of the food and said nothing could be taken away by Qin Jiyan's people. This was the idea of the northwest army.

For the sake of this batch of grain and grass, even if they die, they have to go to Qingzhou City.

The king of Zhao is leading people in the front, and his two sons are also in the middle. They don't know that in the rear, Qin Yunchu is secretly contacting people who support him. Under their instigation, they have the intention to compete with the two brothers.

The king of Zhao never paid attention to Qin Yunchu. In his eyes, Qin Yunchu is a guy who can't accomplish enough and can't succeed. It's a waste of time to put his eyes on him.

Because of the neglect of Zhao king, Qin Yunchu lived like an invisible man in the army, and his small movements were naturally ignored.

The king of Zhao led the army out of the camp and repeatedly told his men to keep an eye on the supplies and not to let anyone near them, especially whether there were ambushes around.

At this time, it's already dawn, and the visible range is about one meter. There are people exploring the way in front of us. We are on guard on both sides. If there is any danger, we will find it immediately.

The army was careful all the way until dawn. After eating steamed bread and drinking water in the same place, he continued to go on the road, but without taking two steps, the Pathfinder came to report, "Lord, the road ahead is blocked by boulders."

There is a narrow path ahead, which is not easy to go. King Zhao was worried that general Cheng would set up an ambush there. Unexpectedly, there was no ambush, but there was one trouble.

"Send someone to clear the road." The king of Zhao frowned and his heart was agitated.

He had a bad feeling, but he didn't know what it was.

A small team of 1000 people went forward to clear the road, but when they saw the stone pile in front of them, they were all dumbfounded.

How on earth did general Cheng's people get it? How long has it been? How can they get so many stones?

The stone mounds that stopped the king of Zhao were not small stones, but huge ones, just like those that fell from the top of the mountain on both sides. They were tightly stacked together, even with few gaps.

In fact, these stones did fall from the bottom of the mountains on both sides. How did they fall?

Thanks to Gu Qiancheng's explosive formula.

His highness Qin ordered people to improve Gu Qiancheng's explosive bag and make a more powerful explosive. However, his highness Qin does not intend to use it in the battlefield for the time being.

Good steel should be used on the blade. His highness Qin will use it when he is ready to fight Xihu. When that time comes, he will be unprepared to kill Xihu.

It was not the hand of general Cheng who stopped the king of Zhao, but the hand of the king of Qin's confidants. Although explosives have been used in Xihu, his highness Qin will not let outsiders know before they are used in the battlefield. Naturally, this outsider includes general Cheng.

It takes about half an hour for a thousand people to clean up a rock heap, but when they clean up the first one, they find that there is still a pile of stones nearby

"Come on, send someone to see if there's anything in the back?" When the head of a thousand households found the problem, he immediately asked people to climb up and have a look, which made the northwest army angry.

"Yes, there are three piles of stones in the back." In terms of half an hour, they spend the whole morning here.

"Quick, report to the king."

The king of Zhao heard that there were four stone mounds in front of him. He was so angry that his face was askew. "How did Cheng do it?"

It's not easy to transport so many stones, and it's not easy to pile them up so tightly.

"The stone rolled down from the mountain. General Cheng should use local materials." The soldier, who was searching for information, climbed up the mountain along the trail and found a little powder foam, "Lord, I found this on the top of the mountain."

There was only a thin layer, but the king of Zhao knew it as soon as he heard it, "this thing has been used in Xihu."

The Xihu people once asked the king of Zhao with explosive powder, but the king of Zhao didn't know what it was. At least the people of the Ministry of war never equipped his soldiers with such weapons.

If you know what it is, King Zhao can't do anything. What he can do now is to send more people to clear up the obstacles on the road. However, the space of this path is limited, so he can't send more people. At most, he can accommodate 2000 people

"Clean it up as soon as possible. We have to leave at once." The longer the delay, the more uneasy the king of Zhao was, butNo matter how anxious the king of Zhao was, it was useless. If they couldn't get there, they just couldn't get there.

As time goes by, half an hour later, the two piles of stones have been cleaned up. Now there is only the last pile of stones left, which can be finished in two quarters of an hour.

Hearing this news, the king of Zhao was relieved, but at this moment, the soldiers who supervised the rear suddenly came, "Lord, the army, the army is coming, general Yan, the army of the imperial court is coming!"

Yan Qing catches up with general Cheng and joins him on the road. He takes general Cheng's 50000 men and horses into his team and takes 80000 men and horses to chase the king of Zhao.

Although there is not much chance of winning the 80000 match against the 100000 or so people of the king of Zhao, Yan Qing is not here to fight, he is here to grab food and grass

In the city, the secret guards spread the news to his highness Qin one by one, and his highness Qin did not avoid Gu Qiancheng. After reading it, he put it in front of Gu Qiancheng.

Gu Qiancheng is not hypocritical. His highness Qin is not worried about her divulging secrets. Why does she pretend to be so high.

"Is Chu Shizi really fooled?" Gu Qiancheng is not optimistic about the plan to incite Chu Shizi. The reason is that Chu Shizi is so stupid. Can he really help him?

His highness Qin also thought about it, but he couldn't find a good chess piece except Qin Yunchu. Only Qin Yunchu, who is at the bottom of his life and not smart enough, is good enough to instigate himself. As for the problem of being too stupid to help him up?

His royal highness Qin only hopes that Qin Yunchu can be a little smarter when fighting for power, but it doesn't matter if he can't fight for the king of Zhao, as long as he can fight for his two younger brothers
