The instant the King of Link entered, all of them tried to check their connection to the King Class Monster.
And as expected, the King of Link's power was still there.
Theo and the Space Saint exchanged looks.
"What should we do?" Theo asked.
"The portal is successful for the time being. I don't feel any obstruction when transporting him. And with the current strength, energy, and stability, I think we can send around a hundred of my size at a time.
"It shouldn't take longer than a minute. So, we can move everyone out faster than we originally expected.
"If the plan works, then we have to measure the energy consumption." The Space Saint asked, "So, how's the situation over there?"
"As expected, the portal is draining the energy stored inside the structure. But from the current rate, I think the portal can last for two hours before we have to refill it again." Theo answered before turning to the World Class Monsters. "I guess we have to send one of you there for everyone's safety. Meanwhile, the rest have to stay here to recharge their energy."
The World Class Monsters nodded to the suggestion. And the Space Saint said, "In that case, we should close the portal after sending the Air King. After that, we shall make the arrangement for the transport."
"A good idea." Theo agreed with him.
In that instant, the Air King landed in front of him and said, "I'm ready, Sir."
"Alright. Make sure you two work together."
"Yes."
"Now go!"
As soon as he received the order, the Air King flew inside. After hearing the conversation between the Space Saint and Theo, the Air King knew that the passage was safe. So, he wasn't that scared compared to the King of Link, who had no idea whether he would succeed or not.
As soon as they successfully sent these two people, Theo and the Space Saint agreed to close the portal.
They stopped pouring the energy into the structure. And the vortex gradually shrank until it eventually vanished.
"…" Theo and the Space Saint looked at each other, realizing that the link still remained. So, they could continue their work without any problems.
"The portal is a success!" The Space Saint declared out loud.
"!!!" The moment the monsters heard the declaration, they let out a roar or cry to the sky, celebrating their success.
Their roar made the ground shake. Even Theo had to cover his ears since he didn't want to hurt his ears.
However, he understood their joy since this was their chance to return.
From that point on, they started arranging the monsters to go through the vortex. They had to move as quickly as possible to not waste energy.
Obviously, Theo became busy. Not only did he maintain the energy in the structure, but he also had to receive thanks from the monsters. Each king and saint came to him to express their thanks again and again.
After all, Theo had made a great sacrifice for them. He left his family in danger because he had to complete the project.
Luckily, they also tried to repay Theo's kindness. Theo had a lot of Skill and Material Cards along with a huge number of elites.
When he returned, there would be a huge upgrade in their group's strength. So, he couldn't help but feel a bit impatient to go home.
It took half a day to complete the arrangement. After that, Theo and the Space Saint opened the vortex again and started sending the people from the other side.
More and more monsters were sent through the vortex. The World Class Monsters kept pouring their energy into the structure to refill it since they wanted to create a vortex that at least lasted for a few days.
Eventually, the number of monsters left in this world shrank to only a thousand. It might be because the number was low that they became a bit more special.
Once that number reached a hundred, the monsters got special congratulations from the Space Saint and Theo.
After another while, there were only World Class Monsters left in this world.
These were the original Saints that worked together on this project. The silver dragon was the first one to leave. But before he left, he ripped a scale from his back and presented it to Theo.
"Take this, Theodore Griffith. It seems that my kin has put you in trouble before. And because you know the old man, you should take this scale. I am a Silver Dragon. My scale might not be as strong as others, but it has the best conductivity of Magic Power. So, it should be useful for you."
"Thank you." Theo nodded with a serious expression, receiving this scale. To think that the previous proud dragon would be this thankful to him, it was surprising even for Theo.
The hairless wolf came to him and extended his paw. "Thank you, Theodore Griffith. I apologize for taking a lot of your time. Although I want to help you in your battle to repay your kindness, I have to leave. That's why you should take this."
Theo was confused, but he still extended his hand until it touched his paw. In that instant, he felt energy start coming into his body.
"!!!" Theo widened his eyes. This energy was similar to the one the Queen of Destiny gave him. But this was much purer. And with Theo's current expertise, there wouldn't be any side effects if he absorbed this energy.
"I don't have anything to give you other than a part of my energy. This should allow you to expand your reserve for a bit. I hope this is useful."
"Thank you."
Then, the humanoid monster came to him and said, "It's good to work with you. Well, I don't know if this can be considered my gift or not, but I have sorted all the excess materials and hidden them in the usual location. If you need them, you can come back and retrieve them."
"Thank you. Those materials are useful."
After receiving the third present, the fourth World Class Monster approached him.
It was the dog saint that looked like a Dobermann. He had been helping him to find the humans and materials, so he was grateful for the Dobermann.
Even so, the dog still left him a small presence.
"You should take these scales." The dog presented him with a weird pale white scale. This was different from the silver dragon scale. So, the dog told him the origin. "I received these scales from a certain snake who lived under the ocean. The conductivity might be losing against the silver dragon scale, but there are several of them."
"Thank you very much." Theo received it gratefully as he looked at these four Saint Class Monsters in front of the vortex.
All of them smiled and said, "Goodbye, Theodore Griffith."
Theo smiled back as he watched them enter the vortex.
Last but not least, the Space Saint. But before he could leave, he had to fulfill his promise to Theo first.
So, he closed the vortex and looked at Theo with a smile. "Sorry for kidnapping you and taking a lot of your time."
"It's fine. I gain a lot from here as well."
"In that case, it's time for me to fulfill my promise."
