"Commander, although we have suffered a lot of losses, the losses of the nezumi are more serious than ours, and I don't think it is very likely that they will attack again!"

"No, this nezumi attack is already very weird, we can't afford to be lucky! And the nezumi have more troops than us, even if the losses are heavy this time, they can recover quickly! Asking for help from the rear is the safest way!" Comicley shook his head.

"Yes!"

After hearing this, Mla did not refute, and what the Commander said made sense, and the nezumi were extremely cunning.

......

The snow-white waves crashed on the hull of the ship, and eighteen huge ships stopped steadily near the port of Heilan, and the warriors of the Knights of the Giant Rat disembarked one after another and gathered in the harbor.

Alan instructed Kant to bring the Knights to the camp outside the Giant Rat City, and he spread his red wings and flew directly to the Giant Rat City, where Abith was already waiting.

"My lord, there has indeed been news of the emergency of the Rat Blood Fortress on the side of Heilan City recently!, but it may be to prevent panic, the news was quickly suppressed by the city lord of Heilan City!"

When the fleet was still at sea, Alan received information from the flying team, not long ago, Alan ordered them to focus on the rat blood fortress There was a tragic man-rat battle, more than 30,000 rat people were like locusts, densely impacting the rat blood fortress, and the rat hunters on the head of the city collided together, for a time the sound of killing was everywhere, the blood flowed like a river, even the flying cavalry in the air could smell a smell of blood, this battle was fought, both sides had a lot of losses.

"Focus on this matter, I want to know the attitude of Heilan City and Giant Wood City towards this matter for the first time!" Alan said in a deep voice.

"Yes!" replied Abis with a respectful salute.

This time, Allen's plan to occupy Heilan Island is the first major obstacle, just the green rat clan can send five thousand rat people to attack the giant rat city at a time, you can imagine how great the war potential of the rat people is, when he heard that more than 30,000 rat people gathered to attack the rat blood fortress, Alan also trembled, this is more than 30,000 rat people!

Allen estimates that if it weren't for the Rat Blood Fortress as a defense, it would be very difficult for the Rat Hunters to block the attack of the Rat Hunters!

After Abyss retreated, Alan went to the garden, spread his wings behind his back, and rose into the air at great speed, flying to a mountain forest by the sea of the Giant Rat City, where Bahamut was now hiding.

At this time, Bahamut was napping, and the two-day long flight made it very tired.

"Master, you're coming!" Bahamut opened his eyes when he felt Alan coming.

"How are you?" Alan said with concern when he saw that Bahamut was not in the right state.

"It's okay! It's just too much physical exertion, and you'll be fine after a while!" Bahamut shook his head and yawned.

"Okay, I won't bother you! you rest first, you will live in this mountain forest during this time, and I will notify you when I need you!" Alan nodded.

Alan flapped his wings, said goodbye to Bahamut, and flew towards the southern border of the Giant Rat City.

After finding the crack in the ground, Antonio stationed the entire Knights of the Blue Wilderness nearby, and Alan landed directly outside the camp.

"I've seen Lord Viscount!" After seeing Allen, the patrolling warriors hurriedly saluted.

Alan nodded in response, and then Alan met with Antonio and the crack in the camp.

"My lord, there should be that blood crystal in this crack!" Antonio said, pointing to the crack in the ground with a faint glow of blood crystal.

The location of the crack in the ground is indeed relatively hidden, he is in a small ditch, covered by two boulders, and only leaks more than half a meter long.

Now after being discovered by the soldiers, the two boulders have been removed, and the entrance to the crack has revealed its original appearance, the length of the crack is about three meters, the entrance is very thin, and it is impossible to pass people at all, but looking inside from the entrance, you can find that there seems to be a lot of space inside.

"Someone, dig up here!" Alan said, pointing to the cracks in the ground.

After Allen's order was given, seven or eight warriors began to dig, and it was not long before a hole in the ground that was vertically downward appeared in front of Allen's eyes, which was originally covered by the dirt above, and only a crack was exposed, but now it was fully revealed.

Looking down from the entrance of the cave, it was dark and dark, and there was no bottom in sight, but Alan could hear the sound of dripping water coming from inside the cave.

Alan ordered someone to bring a few stones and threw them from the entrance of the cave in turn, and found that within two seconds, he could hear the muffled sound of the stones hitting the ground, which can be inferred that the hole should be more than ten meters deep.

Looking at the hole more than a meter wide, Alan propped up the elemental barrier to protect his whole body, and slowly descended with his feet supporting the cave wall.

"Boom!"

Alan fell to the bottom of the cave, followed by Antonio and Bud, all three of whom had the strength of a mid-level knight at the very least, and could escape quickly even if they encountered danger.

Alan commanded the flames, dispelling the surrounding darkness, the line of fire was like a fire snake, swimming wantonly on the ground, Alan roughly saw the surroundings, under the hole is a zigzag tunnel, this tunnel has traces of human digging, the surroundings are extremely silent, only the continuous sound of dripping water can be heard, this water droplet hits the rock below, the sound is like a burst of footsteps, it sounds palpitating and frightening.

On both sides of the tunnel, there is a more than one meter tall and covered with black spots at intervals, some of these statues are laughing, some are contemplative, some are crying, there are various expressions and postures, seeing these statues Alan knows that he has come to the right place, this tunnel should be dug by the nezumi.

According to the direction of the statue, Alan took Antonio and the two to move inside, and after walking for a while, Alan found a few white bones lying on the ground not far away, and after checking closely, he found that these should be the remains of the rat people, and I don't know why these rat people died here?

As Eren continued to advance, Eren realized that the ground was actually sloping downward, meaning that they were going deeper into the ground.

After walking for more than ten minutes, Alan came to a huge cave, which was more than 20 meters high and had a huge area, and the walls of the cave were inlaid with many stones that could shine, illuminating the entire cave.

The cave is surrounded by a circle, there are many statues carved in the cave wall, these statues are holding weapons, they look very mighty, the ground is flat, the surrounding is empty, only a high platform is built in the center, the high platform seems to be made of huge bluestones, there are four stone pillars above the high platform, respectively in the four corners, the stone pillars are not high only half a meter, and there are vague golden lines on it.

Alan cautiously stepped on the stone steps and walked towards the top of the platform.

In addition to the four gold-veined pillars on the high platform, there was also a blood-colored transparent oval stone in the center, which should be the blood crystal he was looking for!
