As soon as the blue water column rushed out of the Water Emperor Ding, it instantly turned into a water dragon with a length of more than 100 feet.

A dragon roar resounded for dozens of miles, and under Li Mu's control, the blue water dragon rushed straight to the direction of the Sea Demon City Tower not far away, with a monstrous aura.

"They want to attack the city, shoot!!"

Seeing that the blue water dragon was rushing in the direction where he and the others were, a blue-haired old man on the upper floor of the Sea Demon City immediately gave an order, and tens of thousands of demons attacked at the same time, sending out dense supernatural attacks, all of which attacked towards the blue water dragon.

Tens of thousands of people launched an attack together, and the picture looked extremely gorgeous, although the attacks of these demons did not seem to be very powerful, because they were all cultivators below the holy level, but due to the large number of people, the momentum caused was still not small.

"Roar!!

Before the attacks of many demons approached, the blue water dragon that had grown for hundreds of feet opened its mouth and roared, only to see a blue sound wave surging out of the dragon's mouth, instantly disintegrating all the attacks of these tens of thousands of demons in mid-air.

After disintegrating the offensive of the demon army, the speed of the blue water dragon increased dramatically, and with a teleportation, it rushed to the black light curtain transformed by the Sea Demon City Protector Array, and plunged headlong into the black light curtain.

"Boom !!"

There was a heavy muffled sound, and as the blue water dragon hit the black light curtain, the ground within a radius of a hundred miles shook violently, and the black light curtain, which seemed to be not weak, also cracked a lot, but it did not shatter and disintegrate on the spot, but it was able to withstand the attack of the blue water dragon.

"The defense of this Sea Demon City's protective array is really not weak, although I can now exert the power of this Water Emperor Ding, but this is not weaker than the ordinary emperor's weapon, and I was actually resisted by it!"

Looking at the black light curtain that was not shattered on the spot after being hit by a blue water dragon outside Sea Demon City, Li Mu couldn't help but be slightly startled.

"It's normal to be able to resist such a powerful attack as the Water Emperor Ding, after all, looking at the situation of this Sea Demon City, the Demon Clan has not spent much effort over the years, but even so, I don't believe that it can resist the attack of the Water Emperor Ding and my Creation Bow at the same time!"

After Xiao Su said a murderous word, the true yuan in his body surged, and he slowly pulled the Creation Bow away, and several Xiao family elders behind him saw this, and they did not sit idly by, and they also injected the True Yuan power in their bodies into the Creation Bow.

"Whoosh!!"

Under the joint urging of Xiao Su and the elders of the Xiao family, a three-foot-long yellow light arrow quickly condensed on the Creation Bow, and then accompanied by the sound of a wind-breaking wind, it shot straight towards the black light curtain outside the Sea Demon City.

Xiao Su obviously did it on purpose, and the direction of the attack of the yellow light arrow he shot was exactly where the water dragon transformed by the Water Emperor Ding attacked the black light curtain.

The blue water dragon was frantically attacking the black light curtain, and at this moment, a yellow arrow shot through the air, impartially, and landed right on the position where the blue water dragon attacked the black light curtain, and the black light curtain was shot through with an arrow.

"Buzz !!"

As the black light curtain was shot through, the entire Sea Demon City's protective array collapsed instantly, while the yellow light arrows and blue water dragons continued to be powerful, and after breaking through the Sea Demon City's mountain protection array, they all fell on the tower of the Sea Demon City.

"Boom !!"

Although the tower of Sea Demon City looked tall and large, under the attack of the blue water dragon and the yellow light arrow, it still couldn't resist, and it exploded in an instant, and the entire city tower was turned into ashes along with the thousands of demons near the tower.

Seeing that the Sea Demon City's mountain protection array and city tower were breached, at this moment, the Wuji Wine Zhongdian and Xiao Family Elders, who had already prepared, opened the domain space and the space spirit treasure at the same time, and released a large number of Quanzhen Guan disciples and the remnants of the Beidou Alliance's tripartite forces.

Although after the battle of Xuanjing Island, the disciples of the Beidou Alliance and other Quartet forces together are less than 10 million, but the momentum caused by these nearly 10 million people is still not small.

Under the orders of the high-level of the Quartet forces, nearly 10 million troops were dispatched in unison and rushed straight into the Sea Demon City.

In the face of the attack of tens of millions of troops from all directions, the Sea Demon City quickly gathered millions of demon armies to fight back, and a great war broke out.

"Peerless senior, your cultivation is strong, please enter the city quickly and see if there is really no demon saint in this Sea Demon City. ”

"Master and Thunder King, please lead people to capture the teleportation square in the city first, first, to prevent reinforcements from other cultivation cities of the demon race, and second, to protect the teleportation array from being destroyed!"

With nearly 10 million troops and demons fighting together, Li Mu hurriedly greeted Wuji and Jiu Zhongdian and the others.

Wu Ji and the others naturally had no objection to what Li Mu said, and they acted according to Li Mu's orders.

"Li Mu, are we going straight to the treasure house of this Sea Demon City, these low-level demons don't need us to make a move?"

Xiao Su looked at Li Mudao with a smile.

"Don't worry about this, I have to destroy all these Demon Source Flowers, if I let this Demon Realm plant continue to multiply, my Beidou Realm will be finished sooner or later!"

Li Mu said and raised his hand with a wave of his hand, releasing tens of thousands of god-killing insects, all of which were god-killing insects of the golden armor level or above.

Under Li Mu's control, these god-killing insects quickly rushed towards those nearby Demon Source Flowers, and began to devour these Demon Realm plants at a speed unimaginable to ordinary people.

"Boom!!"

After ordering the god-killing insect to devour the Demon Source Flower, Li Mu was about to enter the city with Xiao Su and the others, but at this moment, a violent True Yuan explosion suddenly came from the Sea Demon City.

This explosion was extremely harsh, and although Li Mu and the others were still outside the city, they could clearly hear it in their ears.

"I don't know whether the human race is alive or dead, I actually dare to enter my Sea Demon City, I think you are looking for death, the law, frozen thousands of miles!!"

As soon as the piercing True Yuan explosion sounded, a gloomy man's voice came out of the Sea Demon City again, and before Li Mu and the others could react, a cold and biting chill spread out from the city.

Although it was far away, the chill that spread out of the city, even if it was as strong as Li Mu, couldn't help but feel a chill down his spine.

"Void Sword Intent, Ten Thousand Voids!!"

Just when Li Mu and the others were greatly surprised by the chill that spread from the city, at this moment, a unique voice came from the city.

As soon as Wuji's voice came out, Li Mu and the others felt another aura of law diffusing from the city, and at the same time, the cold and biting chill became much weaker.

"It's not good, it seems that there is really a Demon Saint level existence in this Sea Demon City, and at least it is the late stage of the Demon Saint, or even stronger!"

Although the icy chill had weakened a lot, Li Mu knew that it must be because of Wuji's move.

Glancing at Xiao Su, Ling Tianxiao and the others, Li Mutian quickly urged to the limit, and a dodge turned into an afterimage and rushed into the Sea Demon City, Xiao Su and the others also followed Li Mu into the city when they saw this.

Although the area of Sea Demon City was not small, reaching a radius of nearly a hundred miles, but under Li Mutian's rapid full flight, he rushed into the central area of the city in an instant.

As soon as Li Mugang rushed into the Sea Demon City, he first saw the armies of the two sides fighting separately in the city, and at the same time, in the air not far in front of him, Wu Ji was in a stalemate with a demon man with long blue hair and a shawl and a white robe.

This demon man looks like he is about fifty or sixty years old, not to mention that he has completely turned into a human form, and the demonic power emanating from his body has reached the peak of the Demon Saint, Li Mu doesn't have to think about it to know that this person's true cultivation in the True Demon Realm must be at the level of a quasi-emperor, and it is definitely not an ordinary quasi-emperor.

At this moment, in the hands of this demon man, one powerful ice attribute law after another was pouring out, attacking Xiang Wuji.

On the other hand, the transparent crystal-like long sword in his hand had already pierced the space in front of him, and all the power of the ice attribute law that the demon man had beaten was introduced into the void to defuse the opponent's attack.

Although it seemed that Wuji was at odds with the demon man, under Li Mu's careful gaze, he found that Wuji had actually fallen behind.

Because the expression on the face of the demon man was very cold, and Wuji's face was already bruised, obviously under a lot of pressure, it looked like he was about to hold on......
