Secret Willow City is located at the bottom of the Wisteria Waterfall, this waterfall is caused by continuous rainstorms, once flooded the Secret Willow City, and then there was a genius named Xiahou Tuyuan, who made a strange shape of the diversion device above the waterfall, so that the water of the waterfall bypassed the Secret Willow City, because of its shape like wisteria flowers, so it got this good name.

Secret Willow City is also known as the Iron Bucket City, after the transformation of Xiahou Tuyuan, so that its shape is like an iron bucket, even if the Wisteria Waterfall is destroyed, no one will have much impact on the Secret Willow City, that is, a bucket of water...... Moreover, there are eight water outlets in different directions, which can release water in time, and the dwellings are in the middle and upper parts of the "bucket", and the lower part is used for water storage and entering the city, which are basically hollowed out, and it is also a place for military training in peacetime.

Xu Kai quickly kept up with Xiahou Xian'er's troops, although Xiahou Xian'er didn't expect Xu Kai to help anything, but his heart was beautiful, and he continued to rush back to Secret Willow City at full speed.

Emperor Yuwen ** entered the Secret Willow City after the morale was high, the commander led by him rode a fierce white tiger, holding a huge long sword in one hand, the most obvious is the scar that cut his left eye, but he was not blind, I don't know how many fierce battles he has experienced, he is Yuwen Gang.

Behind the city gate is a large circular clearing, and on the opposite side is a huge iron gate, where there are no soldiers, like an empty city.

"Xiahou Lao'er! Why don't you come out and die? "Yu Wengang was born to be a big horn, and with his deep internal strength, there were cracks in the surrounding walls under the roar......

"Hahahaha! Worthy of the Imperial Marshal, Secret Willow City has been shaken by your voice. "An old man with a white beard appeared on the walls of the inner city, and all the soldiers stood on the left and right, waiting solemnly.

"Why are you guarding this broken city when you're so old? It's better to obediently hand over the spirit stone fragments to me, so that you can live for a few more years!" ”

"Spirit stone fragments? What's that? Xiahou Tuyuan didn't know what Yu Wengang was referring to, because the spirit stone fragment Yipu Xilong was a token of love given by Ling Hubin to Xiahou Xian'er, and he didn't let him see it.

"Since you don't eat and drink in the toast, then you should die! Assault of the whole army! As soon as Yuwen gave the order, Emperor Yuwen** immediately rushed to the iron gate opposite.

Xiahou Tu was far from silent, and when their entire army entered the city, the city gate suddenly closed, and the musketeers who were ambushed on the surrounding walls began to attack Emperor Yuwen**, a good move to close the door and beat the dog!

Yuwen Gang's internal strength exploded, forming a huge protective film, blocking all the flying bullets outside, but the soldiers who were far away were not so lucky, and they were quickly killed by stray bullets, and Emperor Yuwen's ** strength was quickly reduced.

Xiahou Tuyuan on the city wall saw that Yuwengang was so powerful, and couldn't help but think of him when he was a child, and ordered to stop the attack, saying: "Yuwengang, for the sake of you growing up with Xian'er, I will let you go today, you go." ”

"Shut up! I do not scarce the sympathy of the enemy! If you show mercy to my men, I will not spare you!" Yuwen just rode a tiger to approach the iron gate, shouted angrily, and slashed at the gate of the inner city with all his strength, but this gate was not ordinarily hard, he was shocked back several meters, his hands were numb, and the Xuanyuan sword, which was known as indestructible, was actually ineffective against this gate......

"Alas...... Or not...... Keep attacking! Xiahou Tuyuan waved one hand, and suddenly it rained down, and Emperor Yuwen was hit hard again.

Watching his subordinates fall one by one, Yu Wengang was both angry and sad, and he finally got shot when he heard the sound of "dang".

But the bullet bent and slipped off him. It turned out that Yu Wengang was wearing a talisman armor - King Kong Tiger Striped Kai, which was made of the hardest metal in the earth space, and ordinary blades could not hurt him at all, and bullets were no exception.

"Humph! How can such a thing hurt me? Yuwen Gang smirked, and Ren Xiahou Tuyuan's soldiers used him as a target.

More than half of Yuwengang's soldiers were wearing heavy iron armor and were invulnerable, coupled with their large number of troops, they quickly ran out of bullets in the Xiahou army, while Yuwengang's forces still had the upper hand.

Despite this, Yu Wengang was still trapped in this iron bucket array, unable to enter or exit, and was very embarrassed, at this time his adjutant Ben Shuili said: "Marshal, there is a big waterfall outside the city, as long as it is blown up, it can flood the Secret Willow City!" And we can also use the buoyancy of the water to rise to the city wall and annihilate the enemy army in one fell swoop! ”

"It's really a clever plan, you are really indispensable to me by my side! Hahaha! Although Ben Shuili is young, she has been fighting with her father for many years since she was a child, she is resourceful, and she has won the trust of Yu Wengang and is an indispensable figure in the army.

In this high-tech era, there is no longer a need for flying pigeons to pass on the book to fight, and Ben Shuili immediately contacted Gongye Liao outside the city and told him the plan.

Gongye Liao smiled: "This little girl is getting smarter and smarter, but it's a pity that her breasts are too small and not my thing." ”

Without further ado, Gongye Liao took the flying troops and went straight to Wisteria Falls.

The sluice gate of Secret Willow City was naturally heavily guarded, but in the face of Gongye Liao's attack, there was no way to return to the sky, and soon the gate of the sluice gate was blown open.

Without this obstruction, the water on the top of the mountain spurted out at once, like a water dragon rushing to the Secret Willow City.

At the same time, the ghost of Zongzheng Yiye sealed all the eight water outlets like a god, and the speed was incredible, worthy of a ghost knight......

Ben Shuili had already ordered people to make a raft before the war, and the soldiers stood on the raft and waited for the water to send them to the city wall.

The water poured into the "bucket" and soon turned into a tank, the water level gradually rose, and Yu Wengang's army also rose to the city wall.

Xiahou Tuyuan looked very calm, he had expected such a move from the enemy army, and he had already prepared for it.

When Yuwen was just triumphant, he gave an order, a powerful electric current rushed down from the city wall, the raft was electrified due to wetness, and the soldiers were wearing heavy armor, which immediately produced a chain reaction, and the whole army was paralyzed after Emperor Yuwen ** received an electric shock.

Just when Xiahou Tuyuan thought that he was in control, Gongye Liao led the flying troops to attack the Secret Willow City from the rear, destroying the discharge device, and Yu Wengang's army regained its vitality.

Seeing that Emperor Yuwen was about to reach the city wall, and the Gongye Liao army in the rear was also rapidly approaching, under the attack of the two masters, Xiahou Tuyuan made a shocking decision......

"Activate the Super Cannon!"

"Huh? Is it really going to start? The generals were shocked, they didn't expect Xiahou Tuyuan to activate this terrible cannon.

"Well, that's all it takes...... "Xiahou Tuyuan can't care about so much for the safety of the residents in the city.

The top of the city wall suddenly opened, revealing a giant heavy cannon facing the sky, the most advanced weapon in this time and space is the cannon, because of the high cost and great power, it has become the most terrifying weapon in this time and space.

Gongye Liao's flying unit just flew above the heavy artillery, and Xiahou Tuyuan wiped out his entire army with a direct shot, there were really no bones left, no wonder even his subordinates were afraid of this heavy artillery, the destructive power was so amazing.

Gongye Liao's escape technique was first-class, and he escaped this catastrophe, looking at the pillar of light in front of him, he broke out in a cold sweat, but he didn't expect Xiahou Tuyuan to hide such a powerful secret weapon.

The heavy artillery reversed the muzzle of the cannon, and it was aimed at Emperor Yuwen who rose up with another blow. Who knew that Yu Wengang actually stood at the front and used his housekeeping skills.

"What can I do with a dead thing? Eat me up - Tiger Roar Punch! Yu Wengang concentrated all his power between his palms, and shot a shockwave shaped like a tiger that collided with the light shot from the Super Cannon.

"What?! ......" Xiahou Tuyuan was shocked, he didn't expect that Yu Wengang's strength actually exceeded the power of the super cannon, and the light was gradually pushed back by him, and in the face of the powerful impact, the super cannon body began to move backwards.

The walls were also affected, and the walls began to crack and were in danger of collapsing.

Xiahou Tuyuan had no choice but to inject his power into the super cannon to increase its power, this heavy cannon is based on energy, and any energy can be absorbed.

With Xiahou Tuyuan's energy, Yuwengang was finally squeezed back, but fortunately, Ben Shuili resisted it with all his strength in the back, otherwise Yuwengang would definitely die.

Seeing this, how could Gongye Liao sit idly by? He hurriedly jumped onto the bamboo raft to assist, and used his special move, Brahma Flame.

Suddenly, three strong lights of blue, purple and red collided violently with a white light, and you came and went, thrilling and abnormal.

Xiahou Xian'er, who rushed to help, saw this scene, she did not rush to attack, and quietly jumped to the wall of the outer city.

Like the city wall of the inner city, the city wall of the outer city is also equipped with the same super cannon, but at this time, Xiahou Xian'er's strength is not enough to launch a powerful attack, so he does not dare to act rashly, lest he be discovered by the enemy, and the heavy artillery will be destroyed and all his efforts will be lost.

Seeing that Xiahou Tuyuan was gradually at a disadvantage, Xiahou Xian'er was very anxious, but she didn't know what to do.

After a long time, Xu Kai finally arrived in Secret Willow City, but he was closed.

At this time, the city gate was closed, and there were bursts of shouting and cheering voices in the city, and the morale of Emperor Yuwen inside was high, which made Xu Kai also enthusiastic.

When Xiahou Xian'er saw Xu Kai below, she jumped down from the city wall and said, "Come and help me!" ”

"Huh?" Before Xu Kai could agree, Xiahou Xian'er had already jumped onto the city wall with him.

"This ...... This is? ......" Xu Kai was shocked when he saw the behemoth in front of him, it was the first time he had seen such a terrifying heavy artillery with his own eyes.

"This is a super cannon that my father spent 30 years researching, it can absorb all the power to attack the enemy, you just need to inject your own power into this container."

"So amazing? I'll try! Xu Kai began to concentrate his energy and transmit the power into the container, which was gradually filled, but in addition to Xiahou Xian'er's was still half off, Xiahou Xian'er showed a disappointed expression and sighed: "It seems that Secret Willow City can't hold ......"

Xu Kai smiled: "It would be nice if Master was here, he has very strong power!" ”

"When is it, is it still too late?" Xiahou Xian'er looked unhappy, because she didn't expect her fiancé to become weaker than herself.

"Of course it's time!" Xu Kai made a move, and in the blink of an eye, he brought Shangguan Feilong to Xiahou Xian'er.

"This ...... What kind of trick is this? Xiahou Xian'er was surprised.

"It's time to do it! Okay, let's not talk about this for now......" Xu Kai hurriedly told Shangguan Feilong about the matter, Shangguan Feilong just put his hand lightly on the container, and the energy of the super cannon immediately rushed to the full, and it almost broke the watch......

"It's terrible...... Xiahou Xian'er was stunned for a while, and then quickly pressed the launch button.
