Far North, Tiejing City. Nearly a month has passed since Wu Zhi mobilized Dousu and traveled three thousand miles by flying boat to attack and kill the Tushan barbarians who were trying to cross the glacier in the far north.

A month ago, the Dousu flying boat led by Wu Zhi searched back and forth along the south side of the extreme glacier twice, but found no trace of the Tushan people, given that many observation posts of the imperial dynasty on the south side of the extreme northern glacier did not report the traces of the Tushan people. Wu Zhi speculated that eighty percent of the Tushan people froze to death on the way over the glacier.

In order to confirm, he commanded the Dousu Flying Boat to go around in a circle from the North Glacier Road to track the traces of the Tushan people's advance.

They went all the way up along the place where the Tushan people worshiped the moon god, and at the height that the flying boat could barely reach, they finally found the group of Tushan barbarians who had been frozen into ice mounds, and Wu Zhi counted the population, there were roughly more than 400 people, which was basically the same number as the number reported by the spies.

The Tushan people actually killed themselves, and the whole army was wiped out on the glaciers in the far north! Wu Zhi couldn't help but be overjoyed, he didn't expect that the Tushan people, who had not been able to kill for thousands of years, would actually cut off the bloodline inheritance in his office. It's pie-in-the-sky!

According to the military regulations of the Wu Dynasty, such military feats could only be confirmed after the heads of Tushan people had to be brought back to the envoys for inspection. Wu Zhi hurriedly ordered the Dousu monk to go down and harvest the heads.

These Dousu monks were also very happy, not only for the military exploits they had picked up for nothing, but also for the fact that they could finally be transferred out of this cold and desolate barren land in the future.

When Wuzhi and the others returned to Tiejing City with more than 400 heads, they almost couldn't recognize the ruined city in front of them. On the formation hub inlaid with spirit stones on the head of the city, there was an iron spear with frozen stubble, like a thorn, pierced into Wu Zhi's throat, making him stammer, but there was nothing he could do.

What the hell is going on?!Wu Zhi roared and rushed into the city, only to find that the situation inside the city was better than expected, most of the people's houses were still intact, and the only one that was seriously damaged was his city lord's mansion.

The surviving guards in the city saw the flying boat hovering in the air, and only then rushed out of the dilapidated city lord's mansion with a howl, and dozens of surviving guards knelt down in front of Wu Zhi, and stammered to tell the previous story.

But it turned out that in the early morning of three days after Wu Zhi left Tiejing City with the Dousu elite, Tiejing City was suddenly attacked by the Tushan people.

In terms of the defense of Tiejing City, Mo said that less than 500 Tushan people would be attacked by 5,000 Tushan people, and they would not be able to easily break through the defense array of Tiejing City. The problem is that the Tushan people who participated in the attack this time were launched from the city. The specific number of people who participated in the attack is not clear, some people say that more than a dozen Tushan people seized the north gate and put in a large number of Tushan barbarians. Some people also say that hundreds of Tushan people have already sneaked into the city, and only on the eve of dawn did they suddenly attack.

Fortunately, this group of Tushan people also knew that their numbers were too thin to cause more trouble, so they only raided one part of the city lord's mansion and destroyed several important facilities in the city, so they fled from the south gate with a roar.

Wu Zhi was shocked and angry at the time, didn't all the Tushan people die on the glacier in the extreme north? How could another elite emerge and attack my Tiejing City?

He carefully deduced the cause and effect of the incident, and finally thought of an oversight, and he hurriedly called for some of the harvested heads to be brought over. After a careful inspection, Wu Zhi's face was already as white as earth, and he was in a cold sweat. At that time, on the glacier, those frozen people were all dressed as Tushan barbarians, and they were frozen one by one, so he didn't check them carefully.

At this moment, I realized that most of the Tushan people on the glacier were pretended to be people from other tribes in the far north, although they looked a little similar, but they could still see the difference if they looked closely.

Wu Zhi speculated that after the Tushan people captured these tribesmen, they cut off their bloodlines through secret methods to make them lose the power to resist, and then dressed these people as Tushan barbarians, and a small group of dead soldiers forced them to climb the glacier.

However, the real Tushan people have been lurking near Tiejing City, and only when Wu Zhi led Dousu to leave Tiejing City, they took advantage of the night to raid and break the city, and then abandoned the city and fled after some killing and plundering.

Most of the scattered cultivators who came to report the whereabouts of the Tushan people were the inner ghosts who had been bribed by the Tushan people with a lot of money, not only lied about the whereabouts of the Tushan people, but also lurked in the city as an internal response afterwards! Wu Zhi finally figured out all kinds of details, he slammed his fist on the bluestone unicorn beast at the gate of the city lord's mansion, and with a bang, the big stone beast had been blasted into countless pieces by him.

"Are Madam and Little Boy all right?" Wu Zhi asked with the intention of being lucky.

"My lord, please mourn, neither the lady nor the little boy were spared. A guard whispered.

Wu Zhi sighed heavily, and said, "Has the treasury been counted?"

A monk in charge of guarding the treasury stepped forward to report: "This group of Tushan people thought they were prepared, and when they broke the gate of the mansion, they divided into two roads, all the way to the back house, and killed people when they saw them." The other way went straight to the treasury, and after prying open the door of the treasury, they looted it on a large scale, and the spirit stone magic weapons in the treasury were plundered by them countless times. ”

The corners of Wu Zhi's mouth twitched slightly, and he said in a deep voice: "Follow me to the treasury to check." ”

An elderly steward couldn't help but whisper a reminder: "The mourning hall of the lady and the little prince is in the backyard, do you want to go first.....

"Go to the treasury!" Wu Zhi roared with a hideous face.

Everyone was silent and could only follow Wu Zhi to the treasury located in the West Courtyard, and Wu Zhi did not explain to everyone, and when he arrived at the treasury, he did not go to see the treasure room where the spirit stone treasures were stored, but went straight to the sword room where the swords were stored.

When he saw the broken door, his heart sank, and when he entered the house and looked at the empty warehouse, even the sword frame was broken into pieces, and the whole person was like a cramped dragon, and suddenly softened.

"Wu Zu's spear is lost!" Wu Zhi muttered, and slowly collapsed to the ground. The relatives around him were quick to hold him, and asked puzzledly: "Isn't Wu Zu's Liaoyuan spear for the imperial city, how can there be Wu Zu's spear in the treasury of the adult?"

It's just that at this time, Wu Zhi's whole body was like a sifting chaff, and he only muttered over and over again, I lost Wu Zu's spear! Wu Zu's spear was actually lost in my hand!

The guards who followed Wu Zhi into the treasury couldn't help but look at each other, wondering if the city lord was too sad and crazy?

Only an old man who had been guarding the treasury for many years couldn't help but sigh and explained to everyone: "I have been guarding the treasury of this Tiejing City for more than 70 years. When I first entered the mansion, I heard a rumor from my predecessor that there was a Martial Ancestor spear hidden in our Tiejing City, but no one knew where it was hidden?"
