Riya: "…" is that the point?
She looked at Samuel speechlessly and then shook her head. "It's impossible for me to use this in combat."
"One, it took too long to form even one. Second, this damn thing consumed a lot of mana to maintain and I don't want to waste my mana," Riya replied and with a wave of her hand, the small formation sphere disappeared.
"Besides, this kind of formation is not suitable for combat because the range depends on how much mana you're willing to invest. Even for magicians, the large amount of mana will be too much for them. Unless you're willing to use a lot of magic cores or mana stones to make it."
Samuel nodded in understanding.
A good combat ability didn't only require sufficient power but also the resources to support it. If they were to force themselves to use such a move that was clearly self defeating… then they would be stupid.
"Anyway, this formation is backed by a lot of mana and there's no problem to run for years," Riya said.
"In other words, it's impossible to destroy." Samuel sighed.
"By the time someone reached rank 9, it'll be too late to stop the world's fusion." Riya patted the pillar and sighed. "Also, there are 8 outer pillars and 4 inner pillars. The previous two pillars that we found on the outer edge were the outer pillars and this is one of the inner pillar."
"The inner pillar required more mana to operate and also located deeper in the crack. Unless they have reached rank 5 and had prepared a lot of things, no one would be able to reach it in a short term."
After Riya knew that this was the World Fusion and Mana Integration Formation, she definitely knew the structure of the formation well.
"Is this a rank 10 formation?"
"Yes, you can say that."
She looked at Samuel blankly as if asking, 'Are you seriously asking that question to me?'
"I have never reached rank 10 so I'm not even qualified to try making it. I only know the theories and this formation had more than 100,000 branches. How many years do you think I'll need to make this formation?" Riya retorted.
Samuel shut up wisely.
He knew that if he were to mention about this matter again, Riya might snap up at him.
But years to make this formation…
Who would do it and why?
"Also, in order for the World Fusion and Mana Integration Formation, the twelve pillars have to be connected to a medium."
"Yes, the World Fusion and Mana Integration Formation basically will allow the world to fuse, so you need something that can bridge the two worlds." Riya thought for a moment and felt that her thoughts before was truly connected at this moment and then said, "In short, there are 12 returnees in total as each of you represent the pillars."
Samuel looked at Riya solemnly. "Does it mean that if we're not in the Green Planet, the fusion will stop?"
"Unfortunately no." Riya could guess what Samuel was thinking and said, "The medium is only needed to activate the formation. So the moment the formation is activated, the medium is no longer necessary."
Their usefulness had ended from the moment they returned to the Green Planet.
Hearing this, Samuel sighed.
When they were sent to that world, they were only ordinary humans. What could ordinary humans do to prevent themselves to be sent to that world?
They could only wait and pray silently.
"Is there anything special about the returnees?" Samuel asked.
"Well, all the pillars had to represent different path, so the main reason why each of us are chosen should be related to the profession we are most talented in," Riya replied. "Or to be exact, the extreme advancement of a certain profession."
Because all of them basically went to the extreme on one path.
Physical path, magic path, and even the side profession could be dug to the point that it became the main profession instead.
Samuel nodded, though not quite understanding.
RIya also didn't explain further to Samuel and she looked at the pillar in front of her. "This is my pillar… it represent the magic and the runes."
"Do you want to destroy it?"
Seeing Samuel's look, Riya chuckled in amusement. "The formation is simply too strong, so it's impossible for me to destroy it. But I know that I can take this special magic core and the time limit for the formation to activate is too long."
"…Are you not afraid that you'll attract the person who made the formation?"
If Samuel counted right, Riya should have taken the special magic core more than once and probably did it several times.
"No." Riya shook her head. "Whoever made the World Fusion and Mana Integration Formation had to stay in the very middle once it was activated. It had to be done until the two worlds are completely integrated which will take a few years but even if we come to him or her, the world fusion couldn't be stopped. And if my guess is right, the shape of this World Fusion and Mana Integration Formation is that of a spear. In that case, I can guess the location of other formations and pillars."
"Even if we kill that person who made it, this World Fusion and Mana Integration Formation can't be stopped?"
"No." Riya knew what Samuel was thinking. "At the center of the World Fusion and Mana Integration Formation, there will be a barrier, a protective barrier. The person who made this formation had to stay there for years or possibly even decades until the two worlds completely fuse and the barrier will disappear."
"Barrier…." Samuel frowned.
Riya glanced at Samuel and added, "The strength of the barrier is the same as the strength of the entire formation. So unless you have the power to destroy the entire formation, you can't destroy the barrier."
