Players are coming, fortunately I have a time travel simulator

After a world ends, there are seven days of rest as usual. Kira Yoshikage purchased the Explosion Fruit and exchanged it for Deidara's Bloodline Limit Explosion Release. This seems logical.

[Kaz took a different approach and was the first to redeem the Multiple Shadow Clone Technique from Naruto. This way, each of his clones also possessed the abilities of an Ultimate Creature, which was also very logical.]

You weren't particularly concerned with improving your teammates. After all, in most cases, you could carry them along, saving them whenever possible. The death of Zhicang Weiqilong was just a special case. You were more concerned with controlling the Lord God; that was your ultimate purpose in coming to this world.

With the Controller still alive, the Lord God, despite being invaded, still defends his last resort. After a full week of attempts, you've failed to successfully detonate gold and items. You've simply been granted more permissions, including the ability to specify the next reincarnation world and modify mission requirements to a certain extent. This is actually sufficient. By specifying a reincarnation world and modifying mission requirements, you can create a near-dead start for the enemy reincarnation team.

Your actions seem to have caught the attention of the "Saints." They have been observing you, and the final confrontation between the two sides is just a matter of sparks.

After browsing a staggering 23674 different reincarnation worlds, you've locked onto Overlord as your next. You still have one more time-traveling enemy to face, and with Bone King as your avatar, Overlord is undoubtedly your home turf.

[You're currently 2/3 of the way through the world quests. From the bounty hunter Lobo to Frieza, your enemies are formidable. Even if a god- or saint-level foe appears at the end, it's perfectly logical. Use your wits wherever possible to resolve them.]

[At the same time, you are also prepared to face those "saints" head-on and achieve your goal in one fell swoop. Before that, you also remembered to save the current time point as a time slice. If there is any danger, you will immediately return to the current timeline. Unless you are killed instantly, you will be invincible.]

Seven days passed in a flash. After a long and careful preparation, you finally arrived at your third main quest. You chose to enter the world of reincarnation.

This time, after the death of Shikura Mikiro, a new teammate has been added, a black man wearing a felt hat and with what appears to be thick lips. His name is Poklock, an ordinary black man from Michigan, whose specialty is being lucky. Lucky? Perhaps. Does this also mean that your next decisive battle will be smooth sailing?

[The next moment, in your mind, you received the mission of this world.]

[Mission 1: Guard the Great Tomb of Nazarick and ensure that it does not fall to the Empire.]

[Task 2: Reduce the number of enemy team members by at least two.]

[Mission Three: Ensure the survival of Ainz Ooal Gown, the Supreme Being.]

[Due to the special nature of the world quest, your special identity 'Guardian' has been successfully established. This identity will replace one of the original guardians.]

This is your supposed home-field advantage. This mission is inspired by the story of Ainz Ooal Gown luring Imperial workers into attacking the Catacombs of Nazarick. It might seem advantageous, but it's actually a bottomless pit. Bone King's goal is simply to test the Catacombs' ability to resist invasion in real life and to gain an excuse to attack the Empire.

[Because the invaders were too low-level, they even deliberately disabled powerful traps and only used the lowest-level servant traps. However, even these low-level traps were difficult for the invaders to resist. Not to mention that there were several powerful floor guardians and area guardians inside.]

[You can also use your time ability to "cut" Ainz Ooal Gown at any time, allowing the Bone King from another timeline to temporarily take over and control the Great Tomb of Nazarick for a short period of time.]

Therefore, this is a situation that is almost impossible to lose for you.

The room before you is dark, illuminated only by scattered torches. Before you stands a middle-aged man, approximately 180 centimeters tall, his skin tanned from frequent sun exposure, wearing a red suit. This must be Demiurge, the Guardians' military advisor and NPC commander of the defense against foreign enemies. He's currently communicating with you.

You roughly listened to the conversation. It meant that you were responsible for stopping the invaders between the first and third levels of the Great Tomb, but you shouldn't take it too seriously.

[It seems the Guardian you're replacing is Shalltear Bloodfallen, the original guardian of the first to third underground floors, the most powerful of the three. This is quite interesting, considering you were once a vampire yourself.]

There were four illegal groups invading the Great Underground Tomb of Nazarick. Ainz Ooal Gown was currently disguised as the adventurer Momon and accompanying them. One group was known as the Four Strategists, led by Hekkeran, a professional two-sword warrior with light armor. He was extremely powerful and possessed high moral character and integrity. Zhou Ning had no intention of annihilating them.

The second team is Green Leaf, who have successfully slain dragons before and are not too weak. The third team is called Tianwu, whose captain is as powerful as the Kingdom's Warrior Captain. They purchased three forest elves from the Church to form a small team. The three forest elves are a guerrilla soldier, a priest, and a forest priest. In other words, they are a team of three supporting soldiers to protect one warrior.

The fourth team is called the Heavy Crusher, led by Gringam. Their black team is a large workshop with fourteen members. Based on your judgment, the enemy team may eventually be hiding within this team.

Considering the mission to ensure the survival of the "Supreme One" Ainz Ooal Gown, it was obviously impossible to let him go as Demetrius had planned. Otherwise, if Ainz Ooal Gown died, the mission would fail.

All you have to do is go all out. As the mission prompt states, each member of your team has replaced a Guardian, and their strength is undoubtedly weakened compared to the original Great Tomb of Nazarick.

[However, you undoubtedly still have an absolute advantage at this point. As long as the opponent's strength isn't incredibly powerful, you can't lose.]

After a few simple retracings, you easily mastered how to activate the first through third levels of the mechanism and how to arrange for the monsters to attack. This wasn't because you lacked confidence, it was simply for fun.

The underground levels 1-3 you're tasked with guarding are tombs, containing numerous traps and undead. You can observe the battlefield through a crystal ball. The alias Feifei is currently following the "Heavyweight Crusher," whom you believe is the most likely hiding enemy team. To your surprise, you spot a familiar figure near Ainz Ooal Gown: a bald man wearing a yellow uniform with a white cape. At first glance, he seems like a minor character.

You couldn't help but breathe in silently. That was One Punch Man. The only time you were defeated was at his hands. And it was in that battle with him that you saw the path to a higher dimension.

Compared to before, after experiencing the trials of the Infinite World, his current strength has undoubtedly reached a new level. Even you can't see through him. He is undoubtedly a formidable opponent. Perhaps this is fate.

[No matter how strong you are, in the face of fate, you are still like an ignorant child, not knowing what is in the candy box.]
