Alan didn't rush closer to the blood crystal, but looked at the four stone pillars.

In addition to the appearance of these four stone pillars, the lines seem to be made of golden runes, but unfortunately because the stone pillars have begun to decay, the appearance of the lines is a little blurred, and this rune has no value.

In addition to the golden runes on the surface that attracted Allen's attention, there was a gray-white crystal inlaid above the four stone pillars, and there were many cracks on them.

However, it seems that due to the passage of time, the elemental power in the Demon Beast Core has been exhausted, the golden rune array has broken and decayed, and this device has completely lost its effectiveness.

Out of caution, Eren added a few flame shields to himself, then walked to the center of the platform and held the palm-sized oval blood crystal in his hand.

Looking at the blood-colored stone in his palm, Alan was slightly happy in his heart, and found the blood crystal, which also cut off the hope of the rat people on Heilan Island to break through the transcendent level, of course, if there are people in the rat clan with strong blood, they can complete the breakthrough through the baptism of disordered blood, but unfortunately there has not been a single one for so many years.

Putting the blood crystal into the Void Bead, he began to look around, wanting to see if there was anything valuable left, but this cave was probably going to disappoint Alan, in addition to this high platform, there were only statues on the four walls and the moon stone in the sky, but unfortunately these two were extremely cheap, and they were not rare things at all.

"Let's go! we've been down for a while!"

Afterwards, Alan took Bard and Antonio back the way they came, and crawled out of the hole, which was completely sealed by the soldiers who Allen had brought some boulders.

In the future, even if the nezuren clan comes here with the blood spar again, they will not be able to find any clues.

......

Thousands of meters in the air, the wind howled, blowing Allen's robe rattle, and eight fist-sized yellow fireballs were seen arranging back and forth, swimming around Allen's body, like a controlled string of beads.

Suddenly, Allen's face froze, his eyes flashed with electricity, and he pointed forward, and eight fireballs seemed to have a spiritual mind, flying towards Bahamut on the opposite side.

"Roar!" said Bahamut, laughing, and then thousands of shining golden threads converged like golden snakes and cut towards the yellow balls.

The golden threads that gathered together turned into eight golden giant snakes, meandering in the air and flying towards the eight fireballs, and when they were about to collide, the eight giant snakes suddenly disintegrated, and then returned to golden threads pierced into the fireballs, and the fireballs were ruthlessly penetrated, and lasted in the air for a few seconds before being extinguished.

Alan is now competing with Bahamut, although it is gratifying to become an elemental knight, but at the same time, his own combat skills must also keep up, and his combat skills can be improved by playing with opponents of the same realm, but to be honest, for opponents, the entire Musen Ling Alan may not be able to find another suitable sparring partner except for Bahamut!

The thousands of golden filaments that broke the fireball did not disappear, but the roots were solid, and they pounced towards Allen, looking at the thousands of golden filaments that were swarming, Allen frowned and did not resist, and quickly retreated to the rear.

"Stop!" Alan snapped.

As Alan reminded him, the golden threads that were in hot pursuit were taken back by Bahamut.

"Hey, hey!" Bahamut smiled, naturally very proud in his heart.

Flapping his red wings and slowly landing on the ground, Alan pondered, now his strength should be at the point where he has just entered the Elemental Knight, and he is not much stronger than other newcomers to the Elemental Knight, if it weren't for Bahamut's spare hand, Alan knew that he would have been defeated long ago.

"Master, now your strength is in the early stage of the elemental knight, but if you want to send out all your combat power, you still have to practice more!" Bahamut said with a grin, very happy to be able to bully Eren openly.

Alan glanced at this guy dissatisfied, he didn't have much hope of defeating Bahamut Allen in the first place, so he didn't show too much loss.

Bahamut is already stronger than himself in the realm of the transcendent level, which is already equivalent to the strength of the human elemental knight Xiaocheng, plus Bahamut is a dragon clan, a naturally powerful race, not to mention that the realm is lower than Bahamut, even if it is on par with him, Alan is not too sure that he can defeat it.

Saying goodbye to Bahamut, Alan quickly flew back to the Giant Rat City.

To the south of the Rat Blood Fortress, inside the Nezumi camp.

【 Fast update 】

In a humble camp, several ratmen in iron armor sat at a table.

One of them, the golden-haired nezumi was a burly man, with a scar on the corner of his mouth, and a fierce look in his eyes, as he calmly listened to the roars of the other two.

"Patriarch Masaya, you idiot, fool! In this battle, because of your order, my black rat tribe has lost more than 5,000 tribal warriors!" a black-haired rat man opened his mouth wide, and his eyes were angry at the rat man named Masaya.

"Patriarch Coolenster, this battle was agreed upon by you, why are there so many losses now, and it is all to blame on me Masaya!" the blonde rat-man Masaya sneered, and seriously showed a look of sarcasm.

"Bang!"

"It's not a matter at all!Masaya, what we discussed before was to use the attack to confuse the Terran army of the Rat Blood Fortress, and then secretly leave with the army without realizing it!

But how did you do it? You fought for the lives of your warriors, and you didn't follow our pre-set plan at all!" another gray-skinned rat-man was furious, and a row of tables stood up, glaring at Masaya.

"No, no, no, I came here according to our agreement, do you think it's that simple to confuse the Terrans? You can deter them by a feint, if that's the case, when the camp was weak the year before last, it wouldn't have been attacked by the Terran army, let alone hit my Golden Rat tribe hard, so these guys are very concerned about the strength of our Chen soldiers in front of the Rat Blood Fortress! If we make any moves, we will definitely attract their attention, especially the transfer of troops!" With a cruel smile on his face, Masaya looked at the gray-haired rat-man Dakawi.

And then he continued.

"This time to storm the rat blood fortress, although many rat warriors died in battle, but it is certain that this time the rat blood fortress must have seen the determination of our rat people to attack the rat blood fortress, and when the time comes, always be vigilant for the arrival of the rat army again.

It's a pity that we didn't even think that we had left the camp with the army!hahaha!" Masaya sneered.

Hearing Masaya's words, Dai Kawi's expression changed, and he felt that Masaya had some reason, so he sat down slowly, but because his own tribe suffered heavy losses this time, he didn't give Masaya a good look.
