Headaches

As she looked at the four-meter tall man on lying down on the table in front of her, who has his chest cut open, Beatrice fell into a bit of thought or a few moments.

Even so, Beatrice knew that she did not have much time to think, and as such, got to work, as a heart, which she had taken out of a living human being floated behind her as she arrived near the man.

Then a moment later, this heart landed into one of the holes in the chest of the man, which had been clearly carved to fit it.

At this moment, though, the second most difficult part of this operation began, as Beatrice now quickly began connecting several large blood vessels to this new heart.

The most difficult part of this operation was of course creating an environment suitable for this heart, which meant shifting the location of organs, creating new blood vessels which connected this heart with the rest of the body, as well as making other, minute adjustments that could lead to the death of the experimental subject.

It took Beatrice around five minutes to fully connect this heart to the rest of the man's body, this was then followed by healing this hole in his chest and going onto the next heart.

Unlike her first two attempts, which went disastrously on the second and fourth heart respectively, this time, Beatrice was able to quickly implant all seven hearts into the body of the man without him immediately dying

But even so, Beatrice, who was in quite a good mood from enjoying herself, suddenly clicked her teeth.

"Another failure," mumbled Beatrice as she looked at the man, knowing that continuing to try to save him would be useless.

Slowly but surely, in just under twenty minutes, the breathing of the man got slower and slower, before eventually stopping completely, signaling the fact that he was dead.

While this was happening, Beatrice quickly examined the man before coming to a conclusion about his state.

The reason cause of death of the man was not actually any sort of injury, but was actually a fundamental design flaw that Beatrice had made when planning him, making Beatrice unable to heal him

As for what particular design flaw this prototype had, Beatrice would have to conduct a much more in depth investigation to find that out.

...

As she looked at the tens of thousands of ants that were moving about carrying pieces of rock from underground tunnels, Beatrice couldn't help but her attention to Antonia, who was standing next to her.

"Antonia, how long do you think this project will take you to complete?" asked Beatrice as she looked at the ant queen who was standing by her side, staring at the ants in front of her.

"Do not mistress, based on the estimate I have created, increasing the underground structure itself should take us at most a single week, making this new part useful though, that could take quite a bit of time," said Antonia as more and more ants emerged from the ground with rocks above their bodies.

Even though digging large underground tunnels would prove both expensive and difficult whilst working with humans, even if one didn't care about the safety of their workers, ants had no such issue, and could easily build out the most difficult part of Beatrice's mission in just under a week.

Hearing this, Beatrice nodded before falling into thought.

"A week, that's shorter than expected, how many ants are there in the colony right now?" asked Beatrice as she watched a bunch of ants carry around a huge piece of metal that she herself designed.

"Right now the colony has about 1.1 million members, but only around ten percent of them are currently working on this colony, as the colony itself if currently experiencing a period of expansion," said Antonia as she waved her antennae, causing a large hole to suddenly appear in the ground, allowing the large piece of metal to pass through it.

Only a few moments later, though, Antonia waved her antennae once again, causing the hole to disappear.

"That's good, do not worry, you just have to keep this pace for some more time, the colony will be allowed to grow freely eventually," said Beatrice before walking up to a rock, which then opened up to reveal a staircase which allowed her to walk through.

Perhaps because she had lived underground for a long time, or because of the fact her earth ants had made more comfortable with the underground, or some other reason, in this life, Beatrice once again decided to live underground.

Sadly, though, soon after she first began doing so, Beatrice discovered some technical difficulties of living underground that she had not yet thought of.

Even though Selena did not seem to pay any sort of attention to it in her last life, living underground had all sorts of difficulties, starting from the supply of air, which although Beatrice did not need, many of her experimental subjects did so, to the obtaining of food for feeding the experimental subjects, to maintaining the structural stability of a home many meters underneath the surface.

Although these problems might seem somewhat trivial, these were just a tiny percentage of the things Beatrice had to deal with.

Another thing that Beatrice soon discovered was the fact that just being underground was nearly useless without any sort of stealth, as any decent mage would quickly find her underground home if they passed by it.

Thankfully though, Beatrice's home island was extremely barren in terms of mage, and at the same time, the mages that existed were trivial to deal with.

This fact gave Beatrice enough time to begin shielding her home from the outside gaze, which then caused an even more difficult to deal with problem.

Mana

Other than specially enchanted materials, which the earth ants were just currently adding, the only way for Beatrice to hide her home was through spells or formations.

Sadly though, no matter which one of them it was, spells or formations, both of them required mana.

Mana which Beatrice would not always be around to give, which would cause major problems.
