In order to adapt to the combat intensity of the Immortal Realm, Cui Si improved the caliber of the Dragon Pattern Cannons, making them larger, longer, and thicker, and they could spray dozens of special Immortal Five Spell Cannonballs condensed together at one time.

Because Cui Si collected a large number of immortal five spells from various sects a while ago, it was more than enough to build ships, so he produced them into cannonballs. Therefore, the artillery shell reserves in Cui Si's hand are also very sufficient, enough for a large-scale battle.

In addition, according to the agreement, the flying boats that were bought were also driving back at the fastest speed, although they could not all arrive before the battle, but Cui Si still had more than 300 five-spell flying boats in his hands to deploy.

All of these flying boats are Heavenly Soldiers and Heavenly Generals, and the commander-in-chief is White Lotus. Although her strength and qualifications are not high, there is no way, she is the only person here who has the experience of commanding a fleet, and no one else can command such a large fleet immediately.

About half an hour later, Cui Si's Chen Tangguan had already fully entered a state of combat readiness.

On the defense of the city, there are 100,000 giant dragon cannons more than 10 zhang long, and there are more than 2 million scattered defenses of various sects.

At their heads, there were more than 300 five-spell flying boats, which were lined up and suspended above the city, arranged into powerful three-dimensional firepower.

In the middle, there is a giant flying boat of more than 5,000 zhang, which is Cui Si's ship, the Five Elements Shenzhou. Cui Si, Huang Jixiang and others were watching from above.

Not long after Cui Si and the others came here, they saw endless black clouds suddenly appear in the distance. On the head of the clouds, there are tens of thousands of demons and monsters, all of whom are powerful monsters above the Heavenly Immortals.

And the most amazing thing is the sea under the clouds. It was a dense, endless army of demon clans, although it was relatively scattered, and there was no strict formation like the uniform and strict formation of the heavenly soldiers and generals, but the huge number was really shocking.

These troops are still dominated by shrimp soldiers and crab generals, and most of them are showing half of their bodies on the sea, showing their teeth and claws at Chen Tangguan in the distance, looking murderous.

According to Cui Si's requirements, the newly built city wall of Chentangguan is more than 1,000 miles away from the sea, which is barely half an inland. The reason for this is entirely to counteract the Kraken's advantage in the sea. In this way, they had only two choices, one was to give up the advantage of the sea, and the other was to activate the Dao method and let the sea flood the distance of thousands of miles.

The former can reduce the offensive and defensive capabilities of the opponent's troops, while the latter wastes the opponent's precious true qi, so no matter which option it is, it is extremely beneficial for Cui Si.

However, the demon clan on the opposite side was obviously not the kind of lord who was willing to suffer, and when the army marched to the shore, they ordered the troops to stop and did not rush to attack.

The seven big demons standing on the clouds slowly discussed while watching the formation that Cui Si put out.

The seven big demons who came to crusade against Cui Si this time, in addition to the two-headed sea snake that escaped last time, there were six other guys who were closely related to the Black Jiao King. Three of them are Sea Dragon Kings and three are Jiao Dragon Kings.

The sea dragon is the ancestor of the dragon clan in the four sea dragon realms, and the Jiaolong is the child of the sea dragon and the sea snake mixed blood. As hybrids, the dragons are not as talented as the sea dragons, but they are also very powerful. They didn't have a particularly good relationship before, they just got by, but since the Four Seas Dragon Realm fell into the hands of Heavenly Court, these guys have established a deep friendship in the long-term battle against Heavenly Court, and they have all become iron buddies one by one.

This is also the reason why after the Black Jiao King died, the three Sea Dragon Kings and the three Jiao Dragon Kings immediately jumped out to avenge him. These three Sea Dragon Kings are his friends and represent the attitude of the Sea Dragon Clan. Those who came to help were the brothers of the Black Jiao King, and one of them even had his own brother, as the so-called brothers who fought the tiger, and the father and son soldiers went into battle, which is the reason.

The appearance of the Sea Dragon King and the Jiaolong King is similar, both are majestic men with a height of more than 300 zhang, but the horns of the Sea Dragon King are blue, which is very beautiful. However, the horns of the Jiaolong King are black, which looks hideous and fierce. After these guys set up their formation, they couldn't help frowning when they looked at Cui Siyan's waiting.

One of the dragon kings said: "Damn, two-headed snake, didn't you say that Chen Tangguan was broken through the city defense by you, and it has become tattered and vulnerable?" But how did I see a steel city defense? ”

The two-headed snake is the abbreviation of the two-headed sea snake, and when he heard someone say this, he immediately said aggrievedly: "My lord, do you think this city defense is still new, and eighty percent of it was built by them, right?" ”

"Well, it seems like this, you see, the city defense is very new, there is not a trace of wear and rust, and there are even many places that have not had time to be treated. There are traces of pouring in the middle, and it is clear that it is not finished! ”

"Even if it is not completed, but in a few days of a month, he can build such a city defense, which shows that this Cui Si is really extraordinary." Another Sea Dragon King suddenly said, "It's hateful, a guy from the Chaos Djinn Clan, why can't he get along with us?" ”

"Who does he care?" A dragon king next to him said angrily: "Anyway, if he kills my brother, he will have to pay for his life!" ”

"That's right, that's it!" Others shouted as well.

"Although that's what I said, before we start fighting, we have to ask clearly, and we can't let people say that we Four Seas Dragon Clan don't understand the rules!" The leading Sea Dragon King said.

This person is a strong man at the peak of Da Luo Jin Xian, and he is the leader of everyone, and when his words came out, he naturally got the unanimous consent of everyone.

"Brother Ao Guangda is right!" The crowd shouted.

After hearing this, the Sea Dragon King named Ao Guang smiled slightly, and then took the initiative to fly forward for a while, turning his true qi into action, and shouted: "The person opposite, which one is Cui Si of the Chaos Giant Spirit Clan?" ”

Cui Si heard him call himself, and he didn't hide it, he came directly to the bow of the Five Elements Flying Boat, and responded lightly: "It's Cui Si below!" ”

Ao Guang glanced at Cui Si, and then sneered: "Sure enough, it's a hero out of a boy!" At a young age, you won the first place in the martial arts conference, you must not know what your surname is, right? ”

"Not really!" Cui Si touched his nose and said indifferently.

"Not really? Then why did you kill my Sea Dragons? Ao Guang said angrily: "Could it be that our Sea Dragon Clan has offended you?" ”

"Do you need to ask?" Cui Si shrugged his shoulders and said: "Chen Tangguan is already my territory, you sneak attacked overnight, broke the seventeen city defenses, and killed countless people, isn't this considered offending me?" ”
