The correct way to open the elf

Chapter 425 High-Level Invasion
Soon after they easily destroyed the soul that was trying to escape, both Feng Yu and the two great magicians felt that something was amiss.

Although the attacks from the underworld did not stop, they became very regular. Large numbers of low-level undead poured out towards the plane gate, but the higher-level undead disappeared.

They thought that either this was a passive response from the undead, or they were planning a big move, a big move that could break through the fortress of the gate of the plane.

However, as expected of the Underworld which is famous for its Skeleton Sea Tactics, although the strong men of the Underworld were determined to fight to the death, they did not rush over rashly. Instead, they used the remaining low-level undead to continuously attack the Plane Gate Fortress for five days.

The powerful ones in the underworld want to use the low-level undead in the underworld to consume the energy of those guarding the fortress, making them tired and letting down their guard.

However, Feng Yu did not relax his vigilance, but became more careful, because he had already sensed the suppressed crisis in the underworld plane.

Inside the fortress, the professional soldiers were already resting in the rest area, and the soldiers currently operating the weapons were all rotated in from the defense forces of Cattail City for training.

However, they are not a full-time fortress combat team, but are designed to provide a rest for those warriors who have become accustomed to fortress combat.

Although the soldiers who are specifically responsible for fighting in the fortress are resting, once other situations arise, they will quickly take over the weapons and join the battle.

On the sixth day, the powerful beings in the underworld sensed that the main material plane had entered night through the concentration of dark elements at the other end of the plane gate.

At this time, a large number of high-level undead were transformed behind the plane gate of the underworld. They stood quietly behind the plane gate, waiting for the orders of the powerful people in the underworld.

"let's start!"

Seeing that there were not many low-level undead who responded to their call and rushed here, the Lord of Bones sighed.

Nearly half of the soul power accumulated in the underworld was wasted by them in these six days. How could they not feel sad?

But they were forced to do so, and it was all because they underestimated the creatures from the main material plane.

The Lord of Bones stood behind the first batch of high-level undead. He was going to rush in with these high-level undead and command them to fight, because there were almost no undead who had awakened successfully among these undead, and they could only rely on command to adapt to the situation.

Moreover, he also wanted to personally meet this fortress that had forced the entire underworld into a desperate situation with no choice but to fight for their lives.

At this moment, the battle inside the Plane Gate Fortress was very easy. The soldiers who were transferred here for training were operating their weapons, killing the undead accurately one by one. They were also in the mood to chat with their companions and exchange ideas about the differences between these undead.

At this moment, the low-level undead in the plane gate disappeared, and were replaced by high-level undead flying in the air and running on the ground. They were wearing magic shields, their bones were solid and dense, and their movements were more flexible and quick.

Feng Yu, Demps and Anthony in the observation room all stood up.

"Let's begin!" said Demps.

"Old man, your plant magic is not suitable for the battle here. Go to the hall at the back and monitor the undead who want to slip away."

Anthony nodded silently, then turned and left without saying a word.

Feng Yu rang the alarm on the table, sending a battle signal to the resting fortress soldiers, and began to put on his own adamantine armor.

There is no chance of luck in this life-and-death battle, and he will not be careless.

"They are all high-level undead. It turns out that they have sacrificed all the low-level undead and transformed them into high-level undead. They want to break through our fortress in one fell swoop!"

"That depends on whether the bones of the undead are harder or our fortress is harder." Feng Yu said and left the observation room.

"Turn on the ventilation system and the fortress cooling system to the maximum, reconnect the oil line of the water gun, and prepare to implement the incineration plan.

Tell the soldiers that from now on, they are not allowed to open the baffles and can only attack through the cat's eye system. Open up the firepower. Facing all the high-level undead, we can no longer save ammunition. "

The guard went out to convey the order, and Feng Yu also came to the attack position, sat on the shooting position of a double-linked anti-aircraft gun, and began to fire at the group of high-level undead that had already rushed halfway.

At this moment, the special armored vehicles acting as roadblocks have retreated to their respective hiding positions to clear the view for shooting, and a large amount of wind has begun to blow out of the ventilation grilles on the walls.

These winds blow into the soldiers' attack positions, then blow away the smoke from the weapons firing, providing the soldiers with a good view and combat environment.

The magic shields of high-level undead were unable to withstand the powerful kinetic energy of anti-aircraft gun bullets. The magic shields of the undead that were rushing over in front of them were shattered in the air, and they flipped over violently, with broken bones flying all over their bodies.

Even the high-level undead were stopped in their tracks by the powerful and continuous firepower of Cattail City, and were unable to advance for a while.

Near the ancient gate of the plane that Feng Yu and his companions could not see, the Lord of Bones had already followed these high-level undead out of the underworld, but he did not go forward to fight. Instead, he leaned against the wall near the gate of the plane.

The Skeleton Lord began to gather magic power to destroy the inner wall of the fortress. Unfortunately, he found that the creatures of the main material plane had spent a huge amount of money to deal with them. The metal of the entire inner wall of the fortress was actually made of a rare magic-averse metal.

The Lord of Bones was a powerful underworld figure who had appeared in the last plane war. Naturally, he had some good things on hand. He took out a sheathed sword from the gap between his ribs, pulled it out and stabbed it into the inner wall of the fortress.

The long sword cut a hole in the inner layer of the Demon-averse Iron. After Lord White Bone took a closer look, he understood what was going on. He swung his sword twice more and created a triangular hole in the Demon-averse Armor. In this way, he cut off a triangular piece of the Demon-averse Iron plate.

The Plane Gate Fortress also revealed its "meaning" in front of the Lord of Bones.

However, what he didn't know was that he not only cut off a small piece of the inner wall of the magic-repelling iron, but also cut off a thin wire in the gap between the inner wall of the magic-repelling iron and the concrete wall.

In the observation room, one of the lit red light bulbs suddenly went dark.

Feng Yu had been keeping an eye on this side. When he saw the warning light go out, he naturally knew that within the corresponding range, there were undead destroying the inner wall of the Plane Gate Fortress.

Feng Yu handed his weapon to the soldier waiting behind him and turned to walk to the highest position.

This is the best location with a commanding view. Unfortunately, the area inside the Plane Gate Fortress near the Plane Gate is already filled with high-level undead, and you can't see any undead destroying the walls.

"Use heavy firepower to eliminate these undeads. We can't let them destroy the fortress for too long."
