Lu Ban, the Gongshu Ban of Lu State.

In ancient times, Luban craftsmen were the first to be in the manufacturing of equipment.

In order to convince Dou Jiande, Xu Mu thought of the survivors of Luban.

After all, six or seven hundred years have passed since the Qin and Han dynasties. They disappeared back then, and now they can’t find anyone.

The greater possibility is to fall apart and turn into major craftsmen sects and pass on them.

After receiving Dou Jiande's promise, Ling Qian began to be fully responsible for the matter.

Not long after, a city guarding equipment was sent over.

Ling Qian quickly transferred it to the front line to support Gao Yaxian in Mingshui City.

Gao Yaxian and the general under Dou Jiande were loyal to Dou Jiande. Because of this, even though he lost the Mingshui defense line and retreated to Mingshui City, Dou Jiande, who was thinking of his old love, still has not been punished for his crimes.

In fact, it is very undesirable to fight head-on with the Turkic Iron Cavalry.

After all, the Turks took the Xueyantuo tribe as their vanguard, and they were not afraid of death and loved field battles very much.

If you want to curb them, you can only take advantage of the city.

...

Mingshui City.

Gao Yaxian, who was over fifty years old, stood on the low city wall, looking at Xueyantuo's tribe who was coming in a fierce manner, his face full of worries.

"Enjoyed father, Mingshui City is too short, so it is not a solution to defend like this. I might as well lead a thousand elite troops to attack at night to see if I can rush to Xueyantuo's troops and win time for our army!" Behind Gao Yaxian, a man in his white robe in his twenties knelt on one knee and said in a deep voice.

Gao Yaxian turned around slowly, looked at his adopted son, and smiled bitterly: "The Turks are fierce, and our army has never conducted a night attack. This move is too dangerous."

"But the adoptive father--" the white-robed young man wanted to say something.

However, Gao Yaxian waved his hand to stop him and said, "Dingfang, the military advisor has heard that a survivor of Lu Ban sent a city guarding equipment, claiming that one weapon will conquer a city. Maybe we can use this equipment to guard Mingshui City!"

In his hand, he was holding a letter from Ling Qian, and told him that a city-defying artifact would be delivered to him tomorrow.

And the young general in white robe behind him was Su Lie.

Su Dingfang did not dare to disobey the orders of his adoptive father, so he could only nod and gave up the idea of ​​a night attack.

Since his biological father died, Su Dingyi joined the army under Dou Jiande.

With his courage, he was promoted from a small soldier and finally attracted Gao Yaxian's attention.

Gao Yaxian had no son and loved him very much, and even accepted him as his adopted son.

It’s a pity that Su Dingfang at this time did not show any talent except bravery.

Therefore... he did not show his strength under Dou Jiande's command.

...

The next day.

Xueyantuo's troops launched a fierce attack.

The city guard equipment assisted by Xu Mu had long been installed on the city tower by Gao Yaxian.

This city guarding equipment, called Wolf Teeth Paw, is divided into two parts.

Part of it is a huge rolling wood. There are iron nails everywhere, which can pierce a person's chest.

The other part is to pull the lever, and use rollers and ropes to reclaim the rolling wood that pushes down the city tower.

Using the leverage principle, it can be reused many times and is extremely labor-saving.

After two hours of fierce attack.

"Entertainment Father! This thing is really a magical weapon! As long as the three of them work together, they can control this thing. Xue Yantuo's tribe has retreated!" Su Dingfang looked excited, and stroked the blood-stained wolf teeth, his heart surging.

Under the low walls of Mingshui City... countless corpses have accumulated.

The Xueyantuo soldiers who climbed the cloud ladder were slapped by wolf teeth while climbing, and their chests were pierced by spikes and fell to the ground.

It can be said that this time the city tower defense was extremely easy.

Gao Yaxian was also quite happy and nodded, stroking his beard and said, "It is indeed a thing of the surviving Lu Ban tribe. Its exquisite structure is unparalleled in the world. The three of them work together to control such a huge thing!"

He looked up at the huge wolf teeth and happily wrote a memorial to Dou Jiande.

Tell Dou Jiande that he had stabilized the situation.

Although Mingshui City is low, as long as the Luban survivors are there, it will be foolproof!

But... he underestimated the fearlessness of Xueyantuo's tribe.

After two hours of rest, Xue Yantuo's troops took advantage of the darkness to launch another battle to climb the city!

He continued to hit until late at night and could not see his five fingers. Xue Yantuo's tribe retreated.

Gao Yaxian and others still stubbornly defended Mingshui City with their wolf teeth.

In front of the city guarding equipment, the Xueyantuo soldiers who climbed the ladder had no way of doing their flesh and blood.

But the next day, Xueyantuo's tribe seemed to be crazy and continued to launch a fierce attack early in the morning.

Regardless of the casualties, Wolf Teeth Pawn reused it many times, and finally... a failure occurred.

That's right, it's a malfunction.

The roller was stuck.

The wolf teeth rolling wood that was pushed down the city tower could not be pulled back to the city tower.

Then Xueyantuo's tribe took the opportunity to climb the city tower. Gao Yaxian, Su Dingfang and others swear to kill the enemy to death, but the city was lost, and Xueyantuo's tribe kept climbing up from the ladder...

The situation was over, Gao Yaxian said in a deep voice: "My lord treats me very well. I will throw away Mingshui first and then Mingshui City. I have no face to meet my lord, and I can only sacrifice myself to the city! Dingfang, you are still young and extremely intelligent. What you lack is accumulation and cannot be buried here with your adoptive father!"

While killing the enemy, Gao Yaxian pulled Su Dingfang with tears on his face and pushed him to the gate of the back city and personally helped him get on the horse.

"Lord, for my devotion to the city, I will not make things difficult for you! Dingfang, after leaving, he will practice military tactics and learn martial arts hard. You must remember that one day, he will kill all the Turks and avenge his adopted father!"

Gao Yaxian roared in a low voice, patted Su Dingfang down his war horse, and watched Su Dingfang leave.

"Entertainment Father--" Su Dingfang bit his lip tightly, rode his horse, and looked back at the rear.

Only Gao Yaxian was seen trapped in the siege of a group of Xue Yantuo soldiers.

One after another, he inserted into his chest.

Su Dingfang held the reins tightly, and the word revenge echoed in his heart.

"Turkish! I, Su Dingfang, will not kill you in this life, and I will not be a human being!"

Su Dingfang's lower lip was bitten and bleeding, but he had no idea.

He lost his father since he was young, and only after joining Dou Jiande's army was Gao Yaxian treated him as his own.

Let him feel fatherly love again.

Most of the reason he played for Dou Jiande was because of Gao Yaxian.

...

Jincheng Palace.

Dou Jiande had just received a good news from Gao Yaxian, saying that he would definitely be foolproof to guard Mingshui City with the help of wolf teeth.

But not long after, he received a report of the fall of Mingshui City from the scout.

Then, Su Dingfang ran back alone.

"The wolf teeth patting malfunctioned and could not be used. Xue Yantuo's troops took advantage of the situation to attack the city tower. The adoptive father had died with Mingshui City..." Su Dingfang knelt in front of Dou Jiande, looking sad.

The causes and consequences of his coming and losing the city this time have been told.

Dou Jiande looked at him coldly.

The entire Gaoyaxian tribe has been killed in battle, and only Su Dingfang survived.

But he had no intention of asking Su Dingfang for any reprimand.

Gao Yaxian followed him for several years, and was loyal to him and was heartbroken. Now he died in the city. If he killed Gao Yaxian's adopted son, he would be unreasonable.

"You go back."

Dou Jiande waved his hand and asked Su Dingfang to retreat.

Although he did not kill Su Dingfang, it was obvious that the latter would no longer be activated as a escaped general.

"Military advisor! Is this what you said about one weapon to conquer a city?"

Dou Jiande was in a very bad mood at this time and turned around and looked at Ling Qian coldly.

It means to provoke a rioter.

Ling Qian waved the feather fan with a calm and calm expression, "Lord, when people are still tired, let alone objects? If you use them for a long time, problems will naturally arise."

The truth he said left Dou Jiande speechless for a moment.

But think about it carefully...
