But in the fairy world, this kind of city defense is just average. If it's just that, then wait for death! Therefore, the city defense of Chen Tangguan has one every hundred miles from the beginning, a total of eighteen!

Twelve powerful city defenses, plus hundreds of thousands of five spell towers, and millions of immortal defenses, allowed Chen Tangguan to not fall for hundreds of thousands of years.

However, there is now a huge flaw in this kind of protection, that is, the lack of Da Luo Jin Immortal-level immortals.

Under normal circumstances, Chen Tangguan should have three Da Luo Jin Immortals in charge, so as to ensure the safety here, even if the enemy is strong, they can at least rely on the city defense array to support the support of other general troops.

However, a few decades ago, the general army of Chen Tangguan fell for the tricks of others because of his arrogance, and led his troops into the sea, but he was ambushed. The Four Sea Demon Clan's ambushes were all around, and they surrounded the troops of the chief soldier at once, and those heavenly soldiers and generals who went out on the expedition almost did not survive, and even the deputy chief soldier who went with them was killed on the spot.

Only the chief soldier escaped by himself, but he was also seriously injured and could not recover. It is precisely because of this that he resigned from the post of the iron-clad general soldier in shame and went back to his hometown to recuperate from his injuries.

This is the biggest loss suffered by the Four Seas Dragon Realm in hundreds of thousands of years, if it weren't for the timely support of other general soldiers, this Chen Tangguan would have fallen at that time.

Although the Four Seas Demon Dragon failed to take advantage of the situation to take Chen Tang Pass that time, it greatly damaged the border pass defenders. Although some troops have been replenished over the years, they still have not recovered, and the most important thing is that the selection of the general army has not been lowered for a long time, making this the weakest link in the Four Seas Dragon Realm.

As a result, after decades of accumulation, the Four Seas Demon Dragon finally amassed a wave of more vigorous troops, intending to raze this place to the ground and take the opportunity to threaten the hinterland of the Four Seas Dragon Realm.

In order to achieve this goal, the Four Sea Demon Dragon's attack this time, I don't know how many troops were invested. Anyway, it can be described as endless.

They first accumulated a tsunami thousands of zhang high on the sea, and then the large army hid in it, rushing all the way, the huge tsunami, mixed with the demonic energy of millions of demon clan troops, was simply unstoppable, and the hundred zhang city defense was too fragile in front of them. The protective divine light and various prohibitions that rose were broken through in just one shot. Then countless demon armies followed the sea current into the city.

Fortunately, Chen Tangguan is not a line of defense, and the layers of prohibition on more than a dozen lines of defense are not vegetarians, and after being broken through twelve lines of defense in a row, this unprecedented tsunami finally lost its strength and was blocked under the city defense. Then, there was an earth-shattering offensive and defensive battle.

Due to the suddenness of the launch of the Four Seas Dragon Realm, Chen Tangguan, who was not prepared, suffered a big loss at the beginning stage, and was killed in a daze in the first wave of sneak attacks. This led to a serious shortage of follow-up city defense forces, and under the impact of the demon army's sacrifice of life and death, five lines of defense were broken in a row in one day.

And now, Chen Tangguan only has the last line of defense to hold on. However, it is also the strongest line of defense. Because behind the defense line are those immortal relatives who live in Chen Tang Pass, and they have burst out with unprecedented energy for their homeland.

In addition, Chen Tangguan's current commander, the deputy chief soldier Tianxue Jian, was also afraid of losing the pass, so he sent his own personal soldiers. In addition, the army of the Four Seas Demon Dragon is not iron-clad, and after breaking through the seventeenth level in a row, they have already penetrated deep into the interior, and they are also exhausted, so under the power of the desperate explosion in the city, they are temporarily helpless.

At this stage of the war, both sides know that they have reached the most critical moment, and whoever retreats slightly will fall into a place of no return.

If Chen Tangguan gives up, as soon as the city's defenses are broken, what awaits them is an unstoppable surprise attack by the demon clan, followed by a bloody massacre. For millions of years, the two sides have accumulated huge feuds, and there is no possibility of reconciliation.

And once the demon clan retreated, then after the Heavenly Court reinforcements came, they would have to retreat. In this way, the previous sacrifice will be in vain.

You know, the seventeen city defenses are not so easy to break? The first twelve city defenses killed an unknown number of shrimp soldiers and crab generals, and the back five were completely broken by life.

According to rough estimates, after this battle, the subordinates of the Four Sea Demon Dragons lost at least tens of millions. Although it is said that the troops of the demon clan are not valuable, they are all fish, shrimp, and crabs that have grown into essence for a hundred years, and their strength is far less strong than that of the immortals. However, they are also distressed by the loss of too much?

At this time, the battle at the head of the city had already entered a white-hot stage.

On the demon clan's side, there are all shrimp soldiers and crab generals!

Shrimp soldiers, one foot taller, humanoid in appearance, but the head still maintains the shape of shrimp. They were covered in armor leaves made of their shells, and they held a bone spear in their hands, which could fly directly to the city with a single bullet from the water dozens of feet deep. It's a pity that often when they fly halfway, they will be cut into two pieces by the immortals at the head of the city with flying swords, or killed by various Taoist techniques. Even if you barely go up, it's just to attract a little more vitality.

The strength of the hundred-year-old shrimp soldiers is equivalent to the Jindan stage of human cultivation, and there is occasionally the existence of the Yuan Infant Stage. These guys are often monks in the Heavenly Realm to the Immortal Realm, so naturally there is only one dead word.

It's just that the number of shrimp soldiers is too much, and they are like crucian carp crossing the river, emerging in an endless stream, and they can't be killed. Tens of thousands of shrimp soldiers jump up almost every moment, which is really annoying. Many immortals died at the hands of these little shrimps because they consumed a lot of money and couldn't cope with it.

As for the crab generals, they are units that are more advanced than the shrimp soldiers, with thick carapaces all over their bodies, generally four or five zhang high, and they have any weapons in their hands, they are not as flexible as the shrimp soldiers, and they can't jump directly to the city. But they have their own unique skills, and they can climb up to them.

If the monks at the head of the city are not powerful enough, it will be difficult to hurt them who are protected by the thick shell, at most they will knock them into the water, and they will come up again after a while, in short, they are more annoying than the shrimp soldiers.

In addition to these two main forces, the Four Sea Demon Clan also has thousands of different varieties. There are fish, snakes, and even dragons and electric eels. Their strength is also different, and Earth Immortals, Heavenly Immortals, and even Golden Immortals have appeared. These guys are mostly a threat to those immortals and heavenly soldiers in the city, and the defenders have to send special masters to fight against them.
