In fact, Roger originally planned to join Alice and the others directly. However, after getting in touch with Wendy through the Hero's Certificate, Roger was helpless to learn: the elven compass showed that the current location of the World Tree Leaf was already in the direction of Yingzhou Island, and the sea elves who appeared before were just to confuse the public.

The importance of the leaves of the World Tree is definitely self-evident, and before that leaf was eaten by others first, Alice rushed straight to Yingzhou Island with the fleet, while the ships of Wendy and the Elemental Legion were anchored on a nearby island.

Roger has been recuperating in the underwater city for so many days, and it is estimated that Alice and the others have probably arrived on Yingzhou Island. Therefore, Roger could only let the Elemental Legion stay honestly first, while he and Sakurahime went to the ruins of the mermaid clan to search for the core of the alchemy city.

In case Alice and the others fail to land on Yingzhou Island and fail to seize the next alchemy city, then the core of the alchemy city that Roger and Sakurahime are looking for now may become the straw that saves lives.

With this thought, Roger went on an adventure with Sakurahime with peace of mind.

Although the Blue Scale Dragon Whale is huge, it doesn't really have any combat ability, and the only attack it can perform is to directly impact the enemy with its huge body. In response to this trait, the merfolk of the Bluescale Clan draped the Bluescale Dragonwhale with a layer of rock armor and installed a sturdy ramming horn in front of the dragonwhale's head.

Even so, the combat ability of the blue-scaled dragon whale is still quite low, and it usually relies on the iron cannon snails attached to its body and the swordfish commandos cruising around it to ensure its own safety.

If you take the blue-scaled dragon whale to the ruins of the mermaid city. If you really encounter a large sea monster such as a sea dragon, the blue-scaled dragon whale will definitely have no chance to escape.

So Roger and Sakurahime eventually chose to leave the blue-scaled dragon whale on the surface. The two of them dive alone to the ruins of the mermaid city.

Because she had to explore in the sea, Sakurahime turned into a mermaid directly. And Roger is still dressed as usual. A full set of strategic treasures were worn on the body one by one. With Sakurahime's mermaid blessing, although it is not as flexible as when it turns into a seal, it is definitely enough.

Relying on the map given by the Blue Mermaid Queen, Roger and Sakurahime approached the ruins of the city smoothly, and then encountered a large group of fishmen.

The leader of the fish-man warriors in the lead was stunned for a moment. Perhaps he didn't expect to encounter an enemy in the vicinity, he looked Roger and Sakurahime up and down for a moment with two dead fish eyes, and then salivated and pounced on the fish-man warriors.

It seems that these fishmen are not having a good time.

Roger sighed helplessly, but spat out a series of bubbles. Then he shook his head and cast the water elemental summoning.

This time, it was still the sea elements who were summoned, and the ninety-nine sea elements quickly responded to Roger's call. However, summoning the sea element in the sea water caused a surprise that surprised Roger.

Since most of the sea elementals' body composition is seawater, these sea elements are almost invisible in the sea, at least the fish people are completely unaware of the arrival of the sea element.

Under Roger's order, the sea elements were completely ruthless, and they directly killed nearly half of the fishmen in the first round of attacks, including even the leader of the fishmen who was not weak, which made the fishmen panic immediately.

However, the blood of the fish-people also spread because of this. This made the sea very muddy, and Roger immediately retreated with Sakurahime.

Fighting in the sea has such a disadvantage, for land races that mainly observe the world with their eyes and ears, once fighting in the sea. The obstruction of vision due to the spread of blood alone was enough for them to have a headache.

Fortunately, Roger summoned the sea elements to block the attack at this moment, and the elemental creatures that rely on elemental fluctuations to lock onto the enemy have no facial features at all, so they are more suitable for fighting in the sea than the fish people. However, it is precisely because of the blood of the fish people that stains the sea red. Therefore, the bodies of the sea elements were also revealed in the blood water, and the fish people immediately fought back.

Roger immediately sensed something was wrong.

The previous round of attacks from the sea elementals had killed nearly half of the fishmen. However, now that the sea elementals have carried out two more rounds of attacks, the movement caused by the fish people is still so big.

In such murky waters. Roger couldn't see how many fishmen were still at war with the sea elementals. However, the [Eyes of True Knowledge] produced by the system was not affected, and in the elemental vision of the [Eyes of True Knowledge], Roger was speechless to find that the fish people were pouring out in a steady stream.

Could it be that this ruin has actually been taken over by a fish-man clan, right?

The corners of his mouth twitched, and Roger carefully stepped back from Sakurahime. In just such a short period of time, the sea elements have already killed nearly three hundred fishmen, although they are all first- and second-order low-level fishman warriors, but this amount is indeed very amazing, and the scattered blood of the fishmen has stirred up this sea area red.

"If this continues, it is likely to attract bloodthirsty fish such as sea devil sharks." Sakurahime didn't speak, but her voice was clearly conveyed to Roger. Roger, who was busy directing the sea elements, didn't notice this, he just nodded slightly, and then took Sakurahime with one hand and began to swim to the side.

Under the onslaught of the fish people one after another, regardless of casualties, the sea elements with the advantage of strength also began to suffer casualties, which made Roger's eyes freeze suddenly.

Compared to their clumsy movements on the sea or on land, the fish people in the sea are obviously much more flexible, and some mid-level fish people are able to dodge the attacks of the sea elementals, and even take the time to counterattack twice from time to time. It is precisely because of this that the sea elementals will suffer casualties, and Roger no longer dares to imagine what a tragic scene it would be if the warriors of the elves or the human race were in such a situation.

However, after all, the strength of the sea elements is as high as the fifth order, and although there have been casualties, they are still firmly entangled with these fish people, making the fish people completely ignore Roger and Sakurahime, who are quietly leaving in the distance.

Avoided the main battlefield. Roger and Sakurahime slipped through the fishmen's defenses from the side and entered the ruins of the mermaid city.

This can be seen from the scale of the ruins. This former mermaid city is not very prosperous, but it has a variety of strategic buildings. It can be regarded as a sparrow, although it is small, and it has all kinds of organs.

Now, of course, all that's left is a remnant.

The fierce battle between the sea elements and the fish people in the distance continued, and a large number of fish people troops went to support, which made the fish people's defense line appear very obvious loopholes, so Roger easily took Sakura Ji through the outer defense line of the fish people and entered the central area of the mermaid city.

Compared to the badly damaged buildings on the periphery, the buildings in the central area are obviously much more intact, but the most important city hall is only a small half. And looking at the traces left nearby, Roger, who has experience in fighting sea dragons, can easily judge it. It was obviously swept away by the rumored sea dragon with its tail.

The alchemy city core of the mermaid clan is likely to remain there, after all, neither the sea dragon nor the fish man has the ability to build an alchemy city, and the alchemy city core of the mermaid clan is of no use to these races.

Even if the core of the alchemy city is no longer in its original location, the fish people who occupy it now must know its whereabouts.

However, in the vicinity of this central area, although the number of fish-man patrols is not large, the quality of the fish-man warriors among them has increased a lot. Compared to the low-level troops led by the third-order fishman leader on the periphery, the strength of the fish-man warriors here is also the lowest third-order, and the strength of the leading fish-man has even reached the sixth order.

Perhaps it was the anomaly on the periphery that caused the fish people to be wary. The cruising fish-man troops are very careful to observe every corner where they can hide, which makes Roger and Sakurahime's situation very bad.

Carefully taking Sakurahime to hide behind a broken wall, Roger stared closely at a fish-man patrol swimming not far away, his brows furrowed.

It's not hard to kill this fish-man army. It's rare that they can't get these fish-people to cry for help or spot the cries of intruders. Once other fish-man troops are recruited, they will be besieged by a large group of mid-to-high-level fishmen. Roger may be able to get out easily, but it is difficult to ensure the safety of the lowly Sakurahime.

This moment. Roger regretted bringing Sakurahime with him.

Perhaps noticing the faint look of regret on Roger's face, Sakurahime raised an eyebrow: "I have a way." ”

Without waiting for Roger to react. Sakurahime swam straight to a group of fishmen who were about to arrive here.

The fish people who spotted the intruder were about to shout, but they were completely enveloped in the light of the water god mirror in Sakurahime's hand.

The originally menacing fish people suddenly had weak limbs. The eyelids closed slightly, and soon they all fell asleep.

The hypnotic power of the merfolk? Or the power of the mirror?

Roger looked at Sakura with some surprise, and Sakura just shook her hair indifferently and swam in front without looking at Roger.

The sleeping fish-man troops had completely lost the ability to resist, and Roger easily killed all the fishheads. And in order to prevent the smell of blood from attracting the attention of other fishmen, Roger used ice magic to directly freeze all the fishmen, and the absolute fish-killers did not see blood.

With Sakurahime's help, Roger easily approached the former city council hall. However, the strange thing is that the surrounding fish-man troops seem to have deliberately bypassed this area, which makes Roger slightly worried, but he finally sneaks in with Sakurahime.

The first floor of this council hall was quite intact, but it was empty in the place where the core of the alchemy city was originally housed, which made Roger a little disappointed.

After all, if the core of the alchemy city is not here, he can only find a way to completely exterminate the fish-people here, and then go to the fish-man's lair to have a look.

Sighing slightly, Roger, who spit out two bubbles, slowly returned the same way, and Sakurahime, who was watching the wind at the door, suddenly turned around and said with a shocked face: "Be careful!" ”

Roger was stunned in his heart, and before he could turn back, he was swallowed up by a huge mouth. (To be continued.) )
