"We've reached the sea floor. Where are we going next?" Lena asked, looking at Nathan, Selena, and Amphitrite.
Nathan didn't have the answer to that question, so he was more bothered with something else, which was the barrier.
He could feel the intense pressure that tried to break his barrier. He could withstand it just fine, but if they went deeper, the pressure would increase tremendously.
He couldn't help but wonder what would happen if he entered a sea trench. His barrier might collapse and he would die in an instant.
Meanwhile, Selena focused on Amphitrite, considering she was the one who could communicate with all creatures in the sea.
Amphitrite pointed in a certain direction. "Nothing resembles a big corpse around here. However, the number of aliens increases in that direction. It's best to start with that area."
Lena agreed. "Sounds good enough. Wait a minute."
Lena raised her hand and formed several chains with a pointy tip. They flew toward the aliens and impaled their bodies before she pulled the chains. The pointy tip had changed its form slightly, grabbing the cores like a claw.
"!!!" Nathan and Selena were surprised one more time. They usually gathered the cores by splitting the bodies, but they never thought Lena would have such a technique.
At the same time, they could understand why Lena developed that technique. In this place, they didn't have a lot of time to gather the cores, so having that technique allowed them to continue their expedition faster.
Meanwhile, when the aliens attacked the boats, most of them simply reached the deck so they could easily dismantle them with swords.
"Oh, this? I developed this technique, but others can use it as well." Lena smiled.
The summoners showed it to them. Most of them could only send forth a single chain, but two of them could send out 4 and 6 chains respectively. Of course, no one was as absurd as Lena, who controlled 15 chains by herself.
Still, even if this wasn't the sea, this kind of technique should allow them to gather cores more effectively.
"What's wrong? Do you want me to teach you?" Lena smirked, teasing Nathan.
"No need. I just need your permission to copy the ability." Selena shook her head.
"My permission to copy? Well, it's not like the ability is a secret. If you can do it, feel free to use it." Lena chuckled, thinking it was hard to copy on their first try.
However, Selena shocked her when she suddenly shot out a chain similar to hers.
", I guess?" Selena impaled an alien, albeit forgetting the fact she didn't know the location of the cores. Hence, when she pulled the chain, it didn't bring out anything. "Ah… Where is the core's location again?"
Other summoners couldn't help but drop their jaws in disbelief, while Amphitrite enjoyed their reactions, as if showing off her summoner's talent.
Nathan just smiled wryly, knowing how talented Selena was in terms of ena manipulation. Even the Sage acknowledged her talent to surpass him.
"I see…" Lena crossed her arms. Flora told her that Selena would be the main wife, and she definitely had the talent to do it. Lena pointed at her eyes, saying, "Try to envelop your eyes with your ena. Coat your eyes for a split second."
Selena and Nathan followed her instruction and actually saw something they had never seen before in that split second. There was a kind of spark inside the alien's body.
"Are those sparks…" Nathan widened his eyes.
"Yes. They give you the location of the core. When you coat your eyes with ena, you should be able to see an invisible enemy, right? That's why ghosts or good assassins have their own invisibility abilities that could hide or mask their ena.
"However, if you only coat your eyes for a split second, the sudden change in the ena saturation in your eyes will give you a glimpse of the ena within their bodies. Of course, it's not usable against an invisible enemy, but this could allow you to see the trace of ena."
Nathan squinted his eyes. The school taught them to coat their eyes to see the alien's ena as those corpses would have their ena gradually disappear because the ena would be condensed into the core. They had been using this trick, but because of this technique, they had to wait for a bit until the alien's ena settled down.
On the other hand, these people didn't have a lot of time in the sea, so they developed a technique that focused on speed.
Nathan politely nodded. "Thank you for teaching us the trick, Commander."
Lena waved her hand, treating it as if it weren't a big deal. "It's not a special technique or anything. Besides, it's only usable if you are experienced in battle and able to remember and process the location of their cores at high speed or else it'll just be a waste of ena.
"If you think it's useful, you can use it. If not, you can forget about it." Lena shrugged. "Anyway, we've collected everything."
"Yes!" A young summoner nodded as all the cores were stored in his backpack.
"In that case, let's go! We don't have time to waste." Lena started advancing.
The people also advanced in their own way since they had different barrier shapes.
Even Nathan looked like a hamster inside a ball. When he walked forward, the barrier was rolling. Only Selena could walk as if she were on the land since all the water had been pushed out around her avatar.
However, Nathan and Selena couldn't help but exchange looks. Both of them realized that there were still a lot of things for them to learn.
Even though they developed the technique due to their environment, the technique was usable even on the land.
If this was true, they couldn't help but wonder what would happen if they looked around the world, seeing how the local summoners used their abilities to tackle the problem in their respective environments.
The possibilities were endless, like Sage Leyfon once said.
They got more and more excited.
