Night fell swiftly.
The sky, still devoid of moon and stars, was illuminated only by the high circle of light, casting a dreamy glow over the land.
In the basin surrounded by mountains, the indigenous people continued to celebrate, as if rejoicing in the hard-won rebirth and saved destinies.
Gratitude poured out towards Rozen and the others, especially towards Karna, who had protected them. Many of the indigenous people were on the verge of kneeling, prompting Rozen's group to hurriedly approach and help them up.
Eventually, the indigenous people set aside their feelings of gratitude and returned to their joyful festivities.
As for what to do in the future, it was not something they could consider at the moment.
On the contrary, Rozen's group had clear objectives.
"Firstly, we must ensure the safety of these indigenous people."
"If their numbers continue to dwindle, it might not be enough to sustain the normal development of human history."
"This is something that must be avoided at all costs."
Olga Marie, Da Vinci, and Roman firmly acknowledged this point.
According to this principle, even if they wanted to take action against the two major divine nations and carry out the mission of recovering the Holy Grail, they should allocate manpower and leave one or two Servants here to guard.
"As for food and water, there's no need to worry anymore. Senpai summoned a herd of deer, and many are still left. The indigenous people seem prepared to raise them, even encouraging breeding. With fruit trees and rivers, they should be able to live here without problems for a long time. The only uncertainty is safety."
Mash expressed concern about this.
Others shared the same sentiment.
Considering the safety of the indigenous people, perhaps it would be necessary to leave someone here. However, Rozen didn't want to disperse the strength he had painstakingly gathered.
Therefore...
"There's no need to send people to guard here. Since this place is already hard to discover, as long as we make some adjustments and completely conceal it, there won't be a problem."
That was Rozen's plan.
In regards to this, Scáthach agreed wholeheartedly.
"Just apply a magical barrier around this area to isolate it completely from the outside. This will not only prevent its discovery but also serve as a defense against external enemies in critical moments. That should be sufficient."
In this way, there would be no need to allocate manpower to continue guarding here; they could leave with peace of mind.
For Rozen, building a rune barrier here wasn't difficult. Scáthach even suggested using Primordial Rune to provide defense against Servants unless they were Caster-class or a divine-tier magus with the highest level of magic. This proposal was met with approval.
"Inscribe runes symbolizing protection and defense on the surrounding mountain walls, and it will create a Rune barrier. With the use of Primordial Runes, even Servants can be repelled. Unless they are a Caster-class mage or an Heroic Spirit with magic at the highest level, it should be enough."
This solution was provided by Scáthach.
In fact, Rozen had already considered this.
Moreover, he didn't just want to build a Rune barrier here; he also planned to use barriers like "Anti-Magic Barrier" or "Eight Array Barrier" to provide comprehensive protection for this basin.
With this level of protection, this place could be considered foolproof. If they could also use spells like "Invisibility jutsu" to shroud the area, it would truly be a worry-free sanctuary.
After all, Rozen's knowledge had greatly surpassed what it used to be. Regardless of the type of magic or spell, he could find a way to integrate it. Creating a fortress in this basin wouldn't be difficult at all.
With Scáthach's assistance, everything was proceeding smoothly.
"So, let Chaldea handle the key points of constructing the barrier and surveying the ley lines."
"With Chaldea's scans and observations, finding the optimal points and ley lines for constructing the barrier is a piece of cake."
"The results should be out soon."
Da Vinci enthusiastically took charge of this task, expressing her pride in Chaldea's technology to Olga Marie and reassuring Roman.
Following Chaldea's guidance, Rozen and Scáthach headed to the surrounding mountain walls. One prepared to affix specially crafted talismans, deploying various magical barriers, while the other was ready to inscribe Primordial Rune, establishing a runic magic defense.
Mash and Karna also didn't stay idle, each taking a batch of talismans from Rozen, preparing to assist in constructing the barrier. They headed towards different directions on the mountain walls.
The group was determined to protect the indigenous people. After all, only if the indigenous people were safe and sound, would Rozen and his team have a chance of defeating the enemies. If the indigenous people were destroyed, human history would be over, and they would lose.
Therefore, even Scáthach wasn't planning to slack off in this matter.
By the way, both Scáthach and Karna had already formed contracts with Rozen, becoming his Servants.
Of course, this was only a temporary contract for this Singularity.
However, even in a temporary contract, both of them could receive magical energy from Rozen, enhancing their strength, and benefit from his command spells, just like the Servants who formed temporary contracts with Rozen in the singularities in Fuyuki and France.
The indigenous people were still unaware of this fact.
Moreover, these indigenous people couldn't comprehend everything happening on this continent. To them, their homeland was invaded by outsiders, and their understanding was limited.
Though many had seen Dragon Tooth Warriors and the ancient Celtic warriors, their understanding of these existences in this mysterious and sparse land was limited. They were forced to accept the reality and view those Dragon Tooth Warriors and Celtic warriors as demons.
They might continue living here until this Singularity was restored, or Rozen's group was completely defeated, accompanying the incineration of human history, and everything vanished together.
However, at this moment, they only needed to feel joy for still being alive; that was enough.
As the night quietly passed, Rozen's group systematically proceeded with the arrangements for this basin.
Until...
"Boom!"
A tent located in the corner of the basin suddenly exploded, turning into fragments.
"Ahhhh...!"
"Yahhh...!"
The sudden commotion startled the indigenous people. Screams and shouts erupted, causing chaos.
Thinking that dreadful demons had attacked, the indigenous people hurriedly ran in the opposite direction of the explosion.
As for Rozen's group, they converged from all directions, swiftly approaching and gathering in front of the tent.
"This is..."
Seeing the tent shattered into pieces, Rozen initially furrowed his brows, but soon understood what was happening.
Then...
"Swoosh!"
A figure swiftly shot out from the exploded tent in front, propelled by the howling wind, and charged straight towards Rozen.
