In the north of Daqingchi, several southeast to northwest mountains lie under the vast sky, these mountains stretch for thousands of miles, contain extremely rich natural resources, all kinds of rare medicinal materials, thousands of years of timber and gold, silver, copper and other huge reserves of minerals, between these mountains are several empty valley corridors, some are barren and inhabited, the arid valleys are endless Gobi and desert, but some are rich and lush, lush forests like huge green carpets spread among the mountains and valley floors, The magician who created these two extreme landscapes in the same area is water, which is the source of life in this semi-arid land.

At the southeast end of these mountain ranges is the sparkling Daqing Pond, and a branch river that flows into the Daqing Pond comes from the northwest, and it is this river that nurtures the green life in a valley, and this river is the Broken Leaf River.

But the days of the Broken Leaf River Valley in July are not easy, the scorching sun is scorching this semi-humid land, the canyon terrain makes the Broken Leaf River Valley add a bit of stuffiness, especially in the mountains and forests and grass mat areas where the Broken Leaf River passes, it makes people feel like they are in a huge steamer, on this day, a cavalry team of hundreds of people is slowly moving south along the Broken Leaf River, this team is the Great Food Envoy who has just returned from Huifu, the envoy is about forty years old, with a pair of puffy eyes, always like he can never sleep enough, he is the henchman of the Great Food Caliph, His name was Ibrahim, and this time he lived up to the trust of the caliphate and successfully mediated the conflict between the Qarluqs and the Uighurs, who would cede 30% of the land and allow the Uighurs to expand westward to Yibohai (present-day Lake Balkhash), but the southern part of the Qarluqs had been occupied by the Tang army. Therefore, the Great Eclipse decided to let the Qarluq people move south to the Yili River valley south of the Yibohai Sea, which was originally the territory of the Turgish people, and it was because of the concessions of the Great Cannibals that the Great Eclipse and the Hui reached an agreement in the east. The two sides formed a strategic alliance to jointly curb the westward expansion of the Tang Dynasty.

As the Qarluqs moved southward, the danger of conflict between the Great Food and the Tang Dynasty was also quietly increasing, and the territory of the Qarluqs moving south was north of Daqingchi, and in this vast land, the Daqingchi Valley was the richest and most fertile land among them. It was like a glittering pearl, and after the Battle of Talas. This place was once controlled by the Qarluqs, but now that the Tang army has occupied Broken Leaf City, and the Daqingchi River Basin has also been included in the Tang Dynasty's sphere of influence, how can the Qarluqs, who have new and old hatreds with the Tang Dynasty, look at Daqingchi and not be able to.

Abdullah enters the Broken Leaf Valley from a mountain pass to the north, which is actually a long and narrow basin. The widest part is more than 100 li, and the narrowest point is more than 100 li. The whole valley is about 700 miles long, Broken Leaf City is located in the easternmost part of the valley, close to the Great Qing Pond, walked for five days, and is almost to Broken Leaf City, Ibrahim came to Broken Leaf City to visit the captured 30,000 Great Food Army, this is a piece of the heart of the new caliph Hadi, due to the Prince Agush land, Hadi tore up the agreement between the previous caliph and the Tang envoy, but in this way. The 30,000 soldiers who were captured by the Tang Dynasty in the Battle of Anxi were hopeless to return home. For this reason, Hadi has also been criticized by some domestic forces. Since Hadi had just ascended the throne, his throne was not yet stable, and the Egyptian army had not yet expressed allegiance to him, so Hadi was not ready to wage war against the Tang Dynasty for the time being.

"Special envoy, a hundred miles further ahead is Broken Leaf City, there are many Tang Army outposts in this area, we must be doubly careful."

He was ordered to send an envoy to the Great Food on behalf of the Qarluqs, thanking the Great Food for the gift of the Qarluqs, who was very familiar with this area, and he pointed to a protruding mountain beam that resembled a fish's mouth about ten miles away in the distance and said: "Special envoy, that mountain beam is called the mouth of the Fish Dragon, and there is a military fortress called the Fish Dragon Fort, we have to explain to them the intention of the Fish Dragon Fortress in order to get by." ”

Ibrahim wiped the sweat from his neck and panted slightly: "Okay! I don't speak the same language as them, so you can report it for me. ”

As soon as the words fell, his guards suddenly retreated, raised their spears and shields, and looked nervously ahead, only to see that in the front and rear of the team, thousands of Tang soldiers suddenly appeared, they held steel crossbows, and aimed at them coldly, and they could all be shot to death on the spot with just one order.

"Who are you?" A Tang army general galloped out, pointed at them with a war knife and said: "This is the military forbidden area of the Tang Dynasty, you trespass without permission, dismount me all." ”

The general of the Tang army is Yan Yun, the deputy general of Cao Hanchen, the governor of Broken Leaves, he received a report from the flying pigeons patrolling the sentry three days ago, an army of unknown origin is coming to Broken Leaf City, the other party is only three or five hundred people, and there is no enemy situation three hundred miles away, Yan Yun knows that this is not an invading enemy army, but Anxi Jiedu made Wang Siyu Marshal happen to be in Yulong Fort today, he led the army to surround them out of prudence.

"Don't do it, we're the envoys of the Great Caliphate." Atney knew a little Chinese, and he hurried to report it immediately.

"The Great Food Envoy?" Yan Yun was a little puzzled, the envoy of the Great Food should not go here when he went to Chang'an, did they actually know that Wang Dashuai was here?

"Are you heading to Chang'an?" Yan Yun slowly put away the knife and asked.

"The general misunderstood." Atni hurriedly explained: "We are the envoys who have sent us to return to Hui, and now on the way back, entrusted by the caliph, the envoy has come to visit the guards of Broken Leaves, and asked the general to convey it. ”

Yan Yun was a cautious person, he didn't dare to make his own decisions, so he shouted to the Great Food Mission: "Put down your weapons, and I will report for you." ”

Artney hurriedly returned to his horse and whispered a few words to Ibrahim, Ibrahim nodded, and shouted a few words to the guards, and the guards threw down their contradictions, untied their scimitars, and piled all the weapons together.

Fish Dragon Fort is ten miles away, is the Tang army stationed in the Broken Leaf during the Tianbao period, strangled the narrowest part of the Broken Leaf Valley, composed of a castle and a ten-mile long city wall, the original garrison of 1,000 people, but since the beginning of this year, the Tang Army began to mine a silver mine near the Fish Dragon Fort, there was originally a small silver mine here, which had been mined by the Turks before, the original idea was not to let the big food prisoners of war eat idle, but with the deepening of mining, it was found that this is a silver mine with great reserves, And it is distributed in flakes, the grade is also very high, and there are gold mines associated with it, Cao Hanchen immediately applied to Wang Siyu, and transferred 10,000 prisoners of war to mine and smelt here, and there was a very good harvest in just a few months, even Wang Siyu, who had just returned to Shule, could not sit still, and personally came to Crushed Leaf to inspect the silver mine.

The silver mine is about two miles away from the fish dragon fort, it is clearly visible from the castle, at this moment Wang Siyu is standing on the castle accompanied by Cao Hanchen, the governor of the broken leaves, silently watching the thousands of naked prisoners of war in the open-pit mine are mining ore, the low horn sound can be faintly heard, a huge smelting mill was built between the mine and the castle, the reserves of coal near the broken leaf are also very rich, the Tang army directly used the charcoal as fuel for refining, in just three months, it was refined into 300,000 catties of crude silver, and there are 10,000 catties of gold, This is just the beginning, and the production will be larger and larger in the future.

Wang Siyu had already sent someone to Chang'an a month ago to report the discovery of silver ore in Broken Leaves, and now he began to consider the future development of Broken Leaf City, after two days of thinking, a clear three-step context map has been formed in his mind, first of all, it is necessary to build an official road from Broken Leaves to Tuoyun Pass, so that the silver ingots of Broken Leaves can be transported into Anxi and Chang'an in time, and he still has 20,000 prisoners of war in his hands, and from Daqing Pool to Tuoyun Pass is controlled by the Tang Army, this road can be completed in a year.

Secondly, he wants to write to the imperial court, if the imperial court allows, he hopes to immigrate from the Central Plains to 40,000 to 50,000 households to break the leaves, where the land is fertile, the water is sufficient, and the climate is also suitable for living, he can give the immigrants the best conditions, so that the broken leaves can not only develop mining on a large scale, but also carry out transit trade, and gradually develop the broken leaves into the largest city in the Zhaowu region, if it goes well, this plan can be completed in three or five years.

Finally, it is the ambition of the governor to move the Anxi Protectorate to Broken Leaves, so that Broken Leaves will become the bridgehead of the Tang Dynasty's westward expansion, and rebuild the majesty of the Tang Dynasty Khan, for a while, Wang Siyu's heart fluctuated, he is only thirty years old this year, maybe he can see the day when the Tang Dragon Flag is planted in the head of Baghdad.

Just when Wang Siyu was thinking for thousands of miles, a hurried sound of horses' hooves interrupted his train of thought, and he saw that the deputy general Yan Yun was galloping towards this side, and Cao Hanchen next to him was slightly surprised, Yan Yun has always been old and serious, and he is so anxious today, is something happening? "Dashuai, I'll take a look."

Cao Hanchen immediately turned around and went down the city wall, and after a while, Yan Yun hurriedly ran up to the city under the leadership of Cao Hanchen, and he half-knelt down and saluted a military salute and reported: "Report to the marshal, the envoy of the Great Food Envoy to Hui passed through here, and he asked to see the supreme general of the broken leaves." ”

Wang Siyu smiled slightly, "In that case, bring him over!" ”

"Marshal, is it appropriate for these prisoners of war to show them?" Cao Hanchen hesitated for a moment and pointed to the prisoner of war in the distance.

"What if you see it, let him see that this is the end of the invasion of my Datang." Wang Siyu waved his hand and resolutely ordered: "Go!" Bring them to me. ”
