After speaking, his slender fingers slid along the hill on the east side of Tiesai City: "Here, this is the Dragon's Back Mountain of the Qinglong Mountain Range, and it is also where the natural danger of Tiesai City lies."

Bao Li looked at the sand table and said thoughtfully, "You mean, we crossed the Dragon's Back Mountain and copied the back road of the wolf army?"

"No!"

Jiang Guanyu shook his head: "Although Longji Mountain is steep and abnormal, and the birds cross to the south, it is not too difficult for masters to climb over, so whether it is Great Xia or the wolf clan, there must be a secret whistle at the foot of the mountain to prevent being sneak attacked."

Speaking of this, Jiang Guanyu's finger slid again, pointing to a river on the west side of Tiesai City: "On the west side of Tiesai City is the Wusha River, a tributary of the Lanling River, the river is wide, the water is turbulent, the reefs are dense, the boats are difficult to travel, the grassland people are not good at water, and Tiesai City does not have a water army, so that the Wusha River has become a place that has been ignored by both sides, although there must be a garrison next to the river, but it is the only place we can break through."

Momo frowned and said, "Not to mention the dense reefs under the Wusha River, even if we can sneak through, but we only have eight people, how can we break the enemy in the face of the wolf clan's 500,000 army?"

"Yes! There are only eight of us, even if we infiltrate the wolf army, what can we do?"

When everyone heard this, they asked puzzled.

"There are clouds in the book of soldiers, and the soldiers and horses go first before they move the grain and grass."

Jiang Guanyu said confidently: "Tiesai City is short of food, how can the wolf clan not lack food, these wolf clan miscellaneous have always used war to feed the war, wherever they go, they grab it, and the military food is all supplemented by robbing the food of my people in Daxia......

"I see."

Bao Li's eyes lit up, and she said in surprise, "You mean to burn the grain and grass of the wolf army, and then intercept and kill the wolf cavalry who are looting everywhere."

"Not bad."

Jiang Guanyu glanced at her appreciatively and continued: "As far as I know, although the southern part of Youzhou has fallen, the wolf clan has not divided its troops to garrison, but wants to take the Tiesai City in one go, and then slowly try to it, and the people of Youzhou have always been strong, although the people's homes were destroyed, they did not choose to give in, but fought separately and harassed the wolf clan army behind enemy lines."

"So, what we have to do next is to burn the grain and grass of the wolf army, and then gather scattered soldiers from all over the country to form the Great Xia Guangfu Army, and constantly intercept and kill the wolf cavalry to loot the grain and grass, so that the main force of the wolf clan will fall into the situation of being attacked by the enemy."

Speaking of this, a fierce color flashed in Jiang Guanyu's eyes: "Since the wolf beasts dare to invade my Great Xia territory, then you must be mentally prepared to come and go."

When everyone heard this, their blood boiled, and everyone's eyes lit up, and they shouted in unison, "Okay, then let them come and go."

"Everyone hurry up and rest now, and when the supplies such as ordnance, cotton clothes and cement are delivered in the evening, let's stay for two more days to help General Zhao stabilize the defensive position, and then set off to implement the next plan."

Jiang Guanyu clapped his hands and asked everyone to go back to their rooms to rest.

As for eating, he had already bought a large number of compressed biscuits and some instant noodles to share with everyone, so he didn't have to worry about it at all.

In the middle of the night, Jiang Guanyu's fifty vests, which had been left outside the city in advance, drove fifty large trucks full of various materials to the south gate of Tiesai City.

After receiving the message from the soldiers defending the city, everyone who had already cultivated their spirits gathered with Zhao Guangxiu and opened the city gate together to greet them.

A quartermaster had already stepped forward and guided the supply vehicles into the munitions depot.

Then there is a special person who is responsible for counting the number and assigning it to the battalion defenders as needed.

Seeing so many military supplies arrived, everyone received cotton clothes and weapons, and the people of the entire Tiesai City were encouraged and cheered.

The Wusha River is rich in yellow sand, and the only thing missing is cement, and now the cement has arrived.

Zhao Guangxiu immediately summoned people to repair the damaged city wall overnight.

In order to speed up the solidification of cement, he also ordered people to cut down a large amount of timber in Longji Mountain overnight, poured oil on it and threw it outside the city wall.

Then a fire was lit, and a raging fire instantly broke out outside the north gate.

The wolf army was shocked, and thought that there was civil strife in Tiesai City.

However, the fire outside the city wall was so bright and thick smoke that it was impossible to get close to investigate.

Several waves of wolf scouts dared to approach and investigate, but were shot on the spot by the defenders with bows and arrows.

The fire burned for three days and three nights.

After the fire was extinguished, the wolf clan was shocked to find that the dilapidated city wall had been repaired.

It was only after the smoke and fire that the entire north gate city wall turned black.

"General Zhao, now that you have enough food, grass and ordnance, can you be sure of holding Tiesai City?"

Jiang Guanyu saw that everything was ready, and immediately called Zhao Guangxiu to ask.

"Unless a subordinate is killed, the wolf cub will never be allowed to step into the Iron Fortress City for half a step."

Zhao Guangxiu confidently made a military order on the spot.

Just kidding, wolf riders aren't good at sieges.

Now the walls have been reinforced, and there are new types of crossbows and new types of compound bows, as well as various types of ordnance.

With hundreds of thousands of troops in hand, and reinforcements from other cities are coming one after another, if he can't hold the Iron Fortress City anymore, he might as well buy a piece of tofu and die head-on.

"It's time for us to hit the road, and as we leave, I have only one request for you, no matter what, the city of Ironclad cannot afford to lose."

Jiang Guanyu's face was unprecedentedly serious.

"We will not fail in our mission."

Zhao Guangxiu led all the generals to bow down and solemnly made a promise.

"Okay, then please."

Jiang Guanyu also led Ning Qingyao and the others to bow down with their fists in unison.

Then, in the reluctant eyes of everyone, many empty trucks drove out of the South Gate.

They did not inform Zhao Guangxiu and others of their plans.

Otherwise, Zhao Guangxiu would definitely not let them take risks in the future.

After leaving the south gate of Tiesai City, the convoy traveled for about half an hour before stopping.

The vests were responsible for driving the vehicle away (in fact, it was a cover-up), leaving only a large truck as a means of transportation for the people, and they bypassed the Iron City and came to the banks of the Wusha River.

"Alright, everybody get out of the car."

Jiang Guanyu parked, let everyone get out of the car, and took out eight sets of diving equipment and distributed them to everyone.

The vehicle was directly abandoned on the shore (in fact, he secretly took it away), and after a full meal, everyone changed into diving suits and dived into the Wusha River.

Although the Wusha River is turbulent and full of reefs, diving is extremely dangerous.

But under Jiang Guanyu's huge spiritual power, all the reefs have nowhere to hide, and under his leadership, everyone has a thrilling and dangerous continuous sneaking.

Even, during this period, he changed the oxygen tank for everyone many times.

Fortunately, everyone has long been accustomed to his magic, and no one questions where he conjured so many oxygen tanks out of thin air.

The stealth lasted for nearly a day and a night, and finally passed through the camp of the wolf cavalry army and came behind enemy lines.
