The so-called master-servant contract was actually an improved version of the slave contract from this world.
It abandoned the use of blood and writing for signing. One only needed to use spiritual power to construct mana on the pet or person.
However, if the other party had strong resistance, the harder it would be to sign successfully. Of course, as long as your strength far exceeded theirs, you could also easily force the signing.
Besides that, the effect was similar to the slave crest. It was just that because it was signed using spiritual power, the control was even stronger than the slave crest.
Soon, Takeru quickly signed contracts with the Filolials. Due to his strong spiritual power, and the Filolials having no resistance to Takeru, he smoothly signed the seven Filolials.
The seven Filolials only felt a slight pain, which quickly disappeared. A special pattern appeared on the Filolials' chests, signifying the successful contract signing.
Actually, besides signing contracts with these ordinary Filolials, Takeru had also long ago signed master-servant contracts with Raphtalia and Rifana.
After all, although he felt the odds were slim, if he could directly take them back to his world, Takeru would have saved two Intermediate Character Manifestation Cards. And in the future, he wouldn't need Character Manifestation Cards for them.
Also, although he wasn't sure if he could take them back, after signing the master-servant contract, they directly gained the Sword Hero's bonus.
Their levels broke through the 130 limit and could continue to level up.
After doing this, Takeru didn't have much else to do. As for the vast number of slimes and the monsters Takeru had created, without thinking, Takeru could take them back to the main world.
The only point was, Takeru wasn't sure if he could take the monsters he had created that had subsequently reproduced.
However, he planned to kill most of them, then revive them after taking them back to the main world. This should also save some points.
After all, even if he could take live monsters back, based on Takeru's guess, living things would have more value than dead ones.
Of course, Takeru would also leave some as test subjects to see if he could directly take their offspring back. If he could, then in the future, when he had monsters he was emotionally attached to, he wouldn't need to kill them to take them back. After all, killing them and changing worlds, even if revived, would create new souls and personalities.
After planning everything, Takeru played with everyone here. Compared to the palace, the environment here was more beautiful and comfortable.
Plus, since the goals in this world were all completed, the remaining days could be spent relaxing.
In the midst of this leisurely life, time passed slowly.
But six days later, Takeru and the others' peaceful life was still broken. A large number of bat monsters attacked the wilderness near the royal capital.
Because it was so sudden, many adventurers hunting there were attacked and injured.
However, the bat familiars were not very strong monsters. Although numerous, they were still killed by the adventurers who reacted.
The subsequent large batch of bats was soon hunted by later-arriving patrol knights. The bat disturbance temporarily subsided.
But the appearance of the bat monsters was only the beginning of a major event...
What followed was a huge roar. Even Takeru, in the royal capital of the Dawn Empire, heard this piercing roar.
After a simple investigation, he sensed that the source of the sound was beyond his perception range. That meant the roar came from monsters over a hundred kilometers away.
If Takeru remembered correctly, the monster's location should be east of the Dawn Empire, in the Tortoise Kingdom.
That meant the distance exceeded five hundred kilometers. The one roaring was the Spirit Tortoise, one of the Four Holy Beasts of this world and the world's guardian beast.
However, it protected the world, not humans.
On the contrary, it collected human souls to stop the waves by slaughtering humans. These bat-type monsters were the Spirit Tortoise's familiars, assisting it in harvesting human souls.
Besides bat-type monsters, there would be many other types of familiars.
Besides that, there would also be a person who would appear in this incident. She was the Spirit Tortoise's heart...
Sure enough, soon, with the intelligence personnel's return, they reported the incident's information. It didn't differ much from Takeru's memory.
Also, the Spirit Tortoise had already caused many casualties in the Tortoise Kingdom and had broken through many checkpoints and autonomous regions.
After obtaining the exact information, Takeru had someone inform Naofumi, Motoyasu, and the others. Naofumi wouldn't stand idly by.
As for Motoyasu and the others, they would probably ignore it like in the original work. Of course, Takeru didn't care about Motoyasu and Itsuki's attitude.
What surprised Takeru was that with the Spirit Tortoise's appearance, his experience bar, which had stopped displaying, started moving again. That meant his level cap could increase again with the Spirit Tortoise's appearance.
But although he could continue to increase, time was short. And without the activation, leveling up quickly would be difficult.
Takeru shook his head and stopped thinking about it.
"Your Majesty, please deal with the Spirit Tortoise. Otherwise, not only the Tortoise Kingdom, but the Dawn Empire might also be threatened!" Hearing the intelligence personnel's report, Mirellia remembered the information she had once seen about the Spirit Tortoise and quickly requested Takeru.
"I know what I'm doing." Hearing her words, Takeru nodded slightly.
Soon, the next day, through special means, the countries got in touch. They decided to send a coalition of knights to subjugate the Spirit Tortoise.
The Four Saint Heroes would act as the coalition's vanguard...
Takeru didn't care about this. He naturally wouldn't miss the opportunity to have special thoughts about the Spirit Tortoise. He agreed to send troops.
Of course, bringing the knights, Diablo, Esdeath, and the others to deal with the Spirit Tortoise was mainly to deter the other countries.
Initially, Takeru didn't plan to go after the Four Holy Beasts that protected the world. But since it appeared so coincidentally at the very end, Takeru wouldn't let it go.
After confirming the journey, Takeru led everyone and many knights to set out. After all, the Tortoise Kingdom was quite far from here.
And with over a thousand knights, Takeru and the others couldn't go very fast, but they weren't slow either.
This incident was their final training exercise. They would run with weights from the Dawn Empire to the Tortoise Kingdom. Takeru required everyone to arrive within four days.
Looking at the neat knights, Takeru shouted "Depart!" Then, the convoy set off towards the Tortoise Kingdom, farewelled by the citizens.
Along the way, Takeru left the empire in the hands of the next king he had controlled. Everyone else followed Takeru to the Tortoise Kingdom.
Neither Diablo nor Emilia stayed behind to guard the empire. After all, everyone would need to return to the main world with Takeru in the future and couldn't stay here forever.
Sitting in the carriage, Beatrice, Emilia, Akame, and the others trained beside Takeru. Raphtalia and Rifana ran quickly behind Filo and the others.
Compared to the ordinary knights, the two bore much greater gravity. Also, having learned Nen, they needed to continuously train their Nen.
It was worth mentioning that Raphtalia was an Enhancer, while Rifana was a Transmuter.
Although unsure if they would fully focus on Nen, using the time to master Nen more wouldn't hurt.
Everyone ran on the newly built roads. Although they were numerous, their movements were relatively coordinated, and their speed was not slow.
At noon, arriving in the wilderness, many knights skillfully set up pots and fires. They simply boiled some water and soup and had lunch with staples like breadfruit.
After resting for about an hour, they packed up again and continued towards their destination.
In the evening, at an open spot in the wilderness, with a simple snap of Takeru's fingers, a thick stone wall quickly rose around them.
Many knights began setting up tents inside. The logistics department quickly prepared food. After all, the expedition was physical work.
Lunch could be relatively simple, but they needed at least one hearty meal a day to support stamina recovery.
Takeru didn't need to worry about the knights' situation. They could handle these things themselves.
Takeru, in the central area, quickly manifested a villa and led the girls to stay there.
