To be honest, this turned out differently for me in a bad way.
I'm expecting hard mode for the weak MC.

However, it turns out to be the author living in male Harem fantasy.
Weak tiny damsel in distress being surrounded by ikemen adults, who are a perfect gentleman, benevolent, understanding, and caring.
Meanwhile, thug-faced male = mob villain.

The story is going nowhere in the last few chapters, just the author living in the self-insert dream.
While the adventure life is too clean and easy, that is off-putting (not realistic).

For god sake, the author should read the title again.

Anyobody can help explain to me,
How do MC dying reduce his synchronization?

IRL,
Exact same moment is kinda impossible.
Saying it must happen within 0.0000000001 seconds of each other, where in actuality, it needs to be even far more precise than that.

So, who will be the cockblock?

Write to the author, it's the only wei

Review:
It's cute,
But the author's mindset is too pink and fluffy, that it is a mismatch for her to write this cultivation story (+ Demonic Sect story).

What went wrong:
Demonic Sect that pampers the MC a lots.
Pink-hearted demonic sect elders, no rivalry, only friendship and talking about cute stuff.
Flirting in the middle of a fight
Chatty small villain
Flirting in the middle of a run.
Enemies doing nothing when telegraphed attacks are coming.
Assassins dropping their guard around their targets
Main Hero magically came out of nowhere to save the damsel in distress.
MC is slow-minded, and minds work like tangled spaghetti (This is not OK in Demonic Sect cultivation genre).
Pedo Main Hero, fell in love with MC when she is 2 years old.

Verdict:
The author should have removed the villain or demonic sect from her work, and stayed away from cultivation, instead write a straight shoujo pampered FL drama.
Currently is a mismatch of story genre and author.

Read only if you seek fluffy stuff.
Don't read if you expect more from the keyword "Villain" "Demonic Sect" "Cultivation"

Flirting in the middle of foes.
Taking sweet time and offering sweet words during a run.

Assassin with no presence detection training.
The target is even sobbing

That's cute and all, but when these demonic sect elders pampered her too much, it just lose the immersion and degraded the story.

Where can I find Steak with 90% discount

Despite all the tease and foreshadowing of new heroines,
We know JP authors are generally overprotective, and it's no different here I guess, MC and Akane (Main Heroine) will be 100% shipped together.

For her ability to "how to hack past the parental locks"?

Translator got DMCE
U have to rely on machine translate

Noice

Wow, all the other characters are stupid beyond stupid.

But MC is also stupid for thinking of sharing his power with many members,
He forgot, that even if one of the members dies, everyone will also reset.

TLDR; Surviving with 50 members is much harder than surviving with only 2 members.

What about Bone Prison, Bone Storm, Bone Lance, Bone Armor?
Those are useless in interpersonal combat?

Like Fer said, "Absolute Command" is not a thing that anyone can do.
Other people just project a will into their summoned Undead, not exactly commanding them.

MC basically leaks that he can command an order on Undead already.

Why are they destroying the precious rune wall?

MC also did not bother to ask, how to create a new battalion commander.
If Fer is gone, puff, all that goodies gone.
