The sound of the horn echoed throughout the iron walled city, and the fish head on the top of the city was gradually wrapped in a huge iron sheet, which was known as the defensive treasure of the King Kong Dome, but in Mu Yuncheng's opinion, it was just a turtle's shell.

The iron-walled city, which was still shining brightly, disappeared into darkness in an instant.

In Mu Yuncheng's opinion, this iron-walled city is a turtle shell, and if he hides here, he will be toyed with and killed sooner or later. Besides, I didn't come to take refuge, and I still had important things to do, so I didn't dare to stay here longer.

"Yun Cheng is here to borrow the Shark Clan's exorcism wand to save people's lives, so he won't stay here longer. Mu Yuncheng bowed and wanted to leave. But the Great Elder of the Fish Clan, Xi Bei, stretched out his hand to stop him and said, "The young man is not only holding the Taiyi Dragon Pattern, but also the grandson of Mu Bufan, so he must have an extremely close relationship with the Sword Saint. This Great Desolate Clan is in trouble, if the Chu Sword Saint encounters it, he will never stand idly by, I don't think Mu Shaoxia will act like this!"

Mu Yuncheng never thought that this old turtle would actually entangle himself, so he explained: "I am not sitting idly by, I really have something important to do! Your iron-walled city is as solid as gold, no matter how brave his wooden mortise army is, it should not be able to attack it!" As he spoke, a huge explosion suddenly came from the dome, and then the bombs made of black sky fire rained down on plantains, beads fell on silver plates, and crackled above the dome.

But except for some dust falling in a row, the Iron Wall City did not move at all. It is worthy of being an iron-walled city, and this Dingdong King is really a great person, who has built such a strong city.

Seeing this, King Dingdong III and Great Elder Xibei also relaxed a little, and the hand that stopped Mu Yuncheng gradually fell.

"If you can't capture here, the Shark Clan should be immediately locked as the next target. Mu Yuncheng's worries are not unreasonable, after all, the demon clan wants to sweep away Cangzhou, and the merman clan and the fish man clan must be eradicated.

But when Grand Elder Xibei heard this, he couldn't help but shake his head and said, "The mermaid clan of the Treasure Sea is very cunning, and their city is built on the bottom of the sea. There is nothing on the Treasure Islands, and it is useless for the wooden tenon army to go. Only on sunny days will they emerge from the water and land on the island to sing. ”

"Even so, I won't be able to get the so-called exorcist wand......" Mu Yuncheng boasted that he didn't have the ability to dive to the bottom of the sea, and the fact that he borrowed the staff was even more nonsense.

Xibei waved his hand, signaling Mu Yuncheng not to worry: "If you dive to the bottom of the sea, I can help you." But you're going to do us a favor. ”

Of course, Mu Yuncheng knew what this help in his mouth was, and then wiped his two fingers over the Taiyi dragon pattern, the sword body trembled slightly, a cold and dazzling eye, and there was a subtle dragon groan.

"You want me to help you fight off the Wooden Tenons?"

Xi Bei nodded repeatedly: "I will open the King Kong Dome slightly, and then as long as the young man helps me resist a little for a while, after I finish casting the spell, summon the tsunami of the dragon god, and then close the King Kong Dome, I can naturally wipe out the wooden tenon army in the wave." ”

"If the Vajra Dome is closed, you won't be able to summon a tsunami?" Mu Yuncheng was puzzled, but listened to Xibei explain: "There is a forbidden array on the Vajra Dome that can be used to block spells outside the city, if you don't open it, how can I successfully cast a spell outside?"

"In that case, please open the King Kong Dome. Mu Yuncheng stroked the Taiyi dragon pattern with his hand, and Qingguang gradually slid from the tip of the sword to the sword grid with his fingers.

Xibei immediately inserted the dragon's head staff into the ground under his feet, and the blue magic circle instantly spread out, illuminating the square in front of the palace.

The King Kong Dome slowly opened, and the starlight and moon shadows condensed into a beam and instantly poured into the Iron Wall City. The wooden tenon army has only been fruitless in a round of attack, and is being loaded and prepared, when a person floats out of the city, the long sword aura under his feet is extraordinary, and his posture is even more free and handsome.

Although the night was thick, his eyesight was extraordinary, and he could clearly see the dense array of wooden tenons and tenons taking off in front of him. Mu Yuncheng stroked his forehead and sighed, feeling tired.

He clasped his palms together in front of his chest, and a sword light gradually burst out from his palms, and the faint sound of a dragon's groan came from it. The sword light was gradually stretched by him, and then turned into two rolling and entangled silver dragons.

With a burst of air, the silver dragon immediately struck out and chased around his chest. Then the double dragon grew bigger and bigger, and thunder surrounded it, blazing the night sky.

"Sword Intent, Double Thunder Dragon", Mu Yuncheng gently pushed with one palm, and the double dragon roared out, and the thunder sparks that burst out from its body gradually filled the night sky, like fireworks, and the thunder dragon ruthlessly devoured one after another wooden tenon demon soldiers that came into view.

Even the powerful wooden tenon army felt a headache in the face of a flexible enemy like Mu Yuncheng, seeing that the wooden tenon that Fang had just taken off was destroyed by Mu Yuncheng's alienated sword qi in the blink of an eye, the angry wooden tenon army began to distance itself from Mu Yuncheng and used magic arrows to **** him from a distance.

The magic arrows glowing with green light were like chains wielded by the god of death, attacking Mu Yuncheng from all directions.

And Mu Yuncheng, who had cultivated the complete "Yin Yang Xuanmu True Sutra", didn't care about such an attack at all, and saw a ball of golden light suddenly spread out from his body, even if the magic arrow was as dense as a rain line, it was also broken at the touch of a button.

There was a loud rumble in the distance, and the sound grew louder and louder, and the ground shook violently. The sea, which had been quiet under the moonlight, suddenly became irritable. Seeing that the tide hundreds of feet high was comparable to a violent wind and rain, it swept in an instant. Mu Yuncheng smiled helplessly, his figure flashed, and the sword turned into blue light and fell back to the Iron Wall City. Among them, there were also Mu Tenon soldiers who planned to burrow into the city through this open gap, but they were all shot outside the city by Mu Yuncheng with ultra-long-range sword qi.

In the face of such a ferocious wave, the King Kong Dome, which was closed again, once again demonstrated the defensive capabilities of the Iron Wall City. In Mu Yuncheng's opinion, such a huge tsunami was enough to destroy a strong city. The iron-walled city of King Dingdong did not move at all under the impact of the waves, only extremely destructive sounds, constantly echoing in the city. And the momentum formed by the falling tide hitting the iron-walled city also caused many houses in the city to collapse instantly.

When the tide receded, the King Kong Dome was fully opened again. There is no longer a figure of the wooden tenon army outside the city, Dingdong Bay has returned to its former tranquility, and Mu Yuncheng seems to be able to see the extremely distorted face of Xing Xuanxi, and he can't imagine that the wooden tenon army that Wanghai City can break through is losing troops in the small Iron Wall City, and how can he, who vowed to pacify Cangzhou within a month, not be angry about this?

"The Great Elder is worthy of being a Water System Grandmaster, and this wave is fierce enough to shake the two realms. King Dingdong III was busy praising Elder Xibei, but when he saw him sigh, he gave all the credit to Mu Yuncheng and said: "If it weren't for this young man, I'm afraid that Tiebi City would be unable to escape." On behalf of the 30,000 people of Tiebi City, thank you in advance. ”

"Well, the young man has made a great contribution, if you have any requests in the future, I will do my best to help Tiebi City. King Dingdong III immediately made a wish to Mu Yuncheng.

Mu Yuncheng bowed his hand, and was not polite, but said: "In this case, I hope that the Great Elder of Annoyance will follow me on a trip to the merman clan and borrow a magic wand." ”

Xibei couldn't shirk when he heard this, even though he was old and frail, he couldn't take a break, so he had to go with him.

As the saying goes, among the five elements, water comes first, and this Xibei Great Elder's water escape technique was instantaneous, and in the blink of an eye, the two of them appeared in the underwater palace of the merman clan.

Mu Yuncheng only felt that the water was magical, and there was even a magical water avoidance technique, which could make him breathe underwater and not be affected by water pressure.

"If you learn this spell, you can come and go freely in the sea. Mu Yuncheng intended to ask Xibei for advice, but he was afraid that he would not teach.

"It turned out that the Great Elder Xibei was here, and I hope to forgive me for my disappointment. "There was a male shark swimming in the distance, but looking at the appearance of Xibei, this person did not seem to be simple.
