Facing the imposing Abyss Demon King, the four tyrannosauruses started their violent forms together, and their eyes and claws became red.

Immediately afterwards, they scattered one after another, going in four directions, invisibly surrounding the Abyss Demon King.

The remaining Deinonychus raised its head and exhaled a fiery breath, summoning a thunderstorm, causing long-range interference to the Abyss Demon King.

Immediately afterwards, it quickly walked around to the back of the Abyss Demon King, making a leap like a hungry tiger, biting the Abyss Demon King's tail and tearing it vigorously.

So the next moment, the snow bear and the elves immediately issued an emergency signal, asking for help from the road army and the watchman in the middle.

At the beginning, he didn't know which direction the Abyssal Demon would attack from, so the road army could only stay in the middle of the cave to command the battlefield, so that no matter which side had trouble, he could support the past as soon as possible.

Upon learning that the Abyssal Demon King had launched a general attack at the north gate of the cave, the Lu Army did not hesitate to grab the watcher's arm and signaled the watcher to start moving.

The watchman who had cooperated with the Lu Army many times also understood the meaning of the Lu Army, and immediately turned on the flashing, leading the Lu Army to the North Gate battlefield instantly.

As for Hongyue, Lin Yilan and others, they continue to stay in the central area waiting for news, because Lin Yilan also opened the space portal, and they can reach the South Gate or the North Gate at any time when necessary...

As the scene changed, the road army and the watchman quickly saw the situation on the battlefield.

At this time, there were about 500 casualties among the snow bear and the elf warriors, most of which were caused by the Abyssal Demon. There were more than 1,000 elf warriors infected with the plague virus, and the situation was very bad.

The line of defense at the entrance of the cave has been opened by the Abyss Demon King, and more undead creatures are pouring in. If the Lu Army and the Watcher come one step later, the battle will be irreversible.

Fortunately, the current situation is still salvageable. The next moment the Lu Army thought about it, they summoned four Tyrannosaurus and one Deinonychus, and stood in front of the Abyss Demon King.

Because this is in the cave, Thunder Dragon and Fengshen Pterosaurs will not stretch out here, so the Lu Army did not let them out, which can save some brain power.

Looking at the familiar dinosaurs, the Demon Lord of the Abyss stopped his movements as if he had seen an enemy, and squinted his eyes with a sense of murder.

It will never forget that night. It was these nasty dinosaurs who severely wounded it and made it shame in front of the undead creatures.

At that time, it secretly swore that if it encounters these dinosaurs in the future, it will kill them for supper.

So the next moment, the Abyssal Demon slashed at the Tyrannosaurus with a double-headed spear that ignited blue flames.

Just after using the double-headed spear to resist the flame and thunderstorm ahead, he felt a sharp pain from his tail, causing the Abyss Demon Lord to frown deeply.

Now the Abyss Demon King began to regret it again. If it could come here earlier, it might be able to prevent the elves from arming their defenses, and the current situation would not be so embarrassing.

However, no matter what, advanced attack is still necessary, otherwise it can only be spent here.

Although the sky was still bright at this time, and the undead creatures under it were a bit sluggish, judging from the sky, it was already afternoon, and it was estimated that it was only two or three hours before dark, so he could make a tentative attack.

So the next moment, the Abyss Demon King sent out brain waves, ordering the undead creatures to attack from both the north and the south at the same time to see how well the defense of the cave is.

Generally, the rough work of charging to death is done by a large number of weak ghouls and skeleton warriors, and this time is no exception.

After receiving the order, thousands of ghouls squeezed towards the entrances of the two caves, densely packed with a look of fear of life and death.

But when they just arrived at the entrance of the cave, they were hit by the snow bears and the elves, turning any undead creatures that dared to approach the cave into a corpse, until the cave was full.

Although the entrance of the cave is small from the outside, the area inside the entrance is actually very large.

Thousands of snow bears and tens of thousands of elven warriors of various types have long built a line of defense inside, and what is waiting is for undead creatures to come in.

Due to the restricted entrance, the undead creatures could not take advantage of the charge, nor could they use the bone dragon bombing attack, making them attack for a long time even unable to enter the hole.

Moreover, the ghouls and skeleton warriors died as soon as they entered, and they couldn't bring out news such as the layout and structure of the cave, making the attack of the undead army difficult.

During this period, the Demon King of the Abyss also ordered the undead creatures to attack other locations in the cave, intending to open up another channel, and even let the bone dragon set the fire above the cave to see if it could collapse the cave.

But none of these methods have any effect. First, the cave is covered with ice that has been frozen for an unknown period of time. Second, the rock structure of the cave is so hard that the attacks of ordinary undead warriors are useless.

Seeing that the corpses of its subordinates had piled up the entire hole, the Abyss Demon knew that this was not the way to go, and it had to take action.

In the next moment, the Demon Lord of the Abyss told the useless ghouls and skeleton warriors to retreat and let out the cave.

Then it began to take the lead in the charge, letting the fat plague ghosts follow it.

Because it considers that the plague ghost will explode after death, spraying the plague virus, and the hole is closed, the plague virus will spread quickly inside, and the effect is definitely very good.

At the moment of entering the cave, the abyss demon immediately used a large amount of flame rain regardless of consumption, almost covering the entire front of the cave.

Then it relied on its own defensive power to be high enough, holding a double-headed spear, slashing left and right, slammed into the defensive formation of the snow bear and the elves, and opened a passage for the plague ghosts.

Although it was beaten by the road army and the dinosaurs in the first two days, its physical strength was greatly reduced, and its combat effectiveness severely declined, but after two days of rest, it has recovered 80% of its physical strength, no different from its peak.

So when the Abyss Demon King was so charged, the Snow Bear and the elves didn't react at once, and casualties began to increase sharply.

Although the snow bears opened their ice shields in time to resist, they also spewed out a large number of blasting snowballs.

But this is not the surface of the river, water is scarce, and the ice shields of the snow bears cannot be broken for a few seconds.

And their blasting snowballs are almost ineffective against the Abyssal Demon Lord, and they can only hit the Plague Ghost.

But even if the plague ghosts die, they can still eject a large amount of plague viruses. Once these viruses are inhaled, they will show symptoms of physical discomfort, causing the defense lines of the elves and snow bears to collapse.

You must know that they are in the cave. There are only one or two lines of defense. If the entrance to the cave cannot be defended, the undead creatures will flood in, and they will be over.
