The next day, a large explosion happened within the city.

At one of the city guard posts when the guards are on patrol, a large explosion occurred which made the whole area crash.

The explosion is of fire element type and everything within the explosion range burned, only a lump of magma and ashes were left behind.

The Night Demon family who are already concerned about the dead investigators, don't know what happened. They don't have much information, they don't know his background, where he came from, and what are his goals in fact they don't even know his name.

They don't know if he is capable of these feats of killing their investigators and causing an explosion within their home ground.

If he suspected him completely and didn't think in any other direction if Sam turns out to be not the person who did all this, things wouldn't go well for any of them.

But they cannot let go of any suspicion either.

The family head looked at all the reports and felt a slight headache. He looked at the attendant who is standing calmly beside him and said.

"Call for the eldest young master. I want him here by evening."

The attendant nodded calmly and left the area. He went out and used a wormhole to go to a different realm. He moved across three realms and finally in a relatively lower grade realm than the Night Demon realm, there is a construction project going on in one of the planets and a young Night Demon is currently supervising it all."

When he saw the attendant, he smiled and waved at him.

"Why are you here at this time? If you were sent here, then it must be an emergency. Is it related to that undead energy invading our fields and mines?"

"That is what we want you to find out young master. The whole situation is confusing. At first, we were investigating a person who is responsible for the destruction of the Blood Demon tribe under our control.

We delayed the investigation because of our undead energy problem, but after we sent the investigators, something else happened. A couple of them seemed to have pissed someone off and they are dead openly.

After that, some of the investigators also went missing and this morning, there was an explosion in one of our city guard posts. We don't know if this is done by the one we are investigating or if it is the work of the people who caused the undead incident.

We cannot be sure that the people our investigators pissed off might be the reason for it.

The family head is having trouble, he would like you to deal with this situation."

"You guys are lucky that I am nearby for my final sect examination. You managed to get rid of that undead incident and now you want me to clean up another mess of yours."

He muttered and said.

"Do you have any clue regarding the person related to the Blood demon family destruction?"

"We have a portrait of the leader. Since we delayed the investigation, not many people remember whoever that was involved, this guy was the only one that left a tad bit deeper impression on some stay survivors of the incident."

With that, the attendant took out Sam's portrait.

The young master took the portrait and was stunned for a second. He felt like he saw the portrait somewhere and started thinking and soon, he seemed to have remembered something and instantly took out a bunch of scrolls from the storage and checked one after the other.

Finally, he managed to find the scroll, and inside there is a portrait of Sam and some details regarding him.

When the attendant saw the portrait he was shocked.

"Young master, do you know of him?"

"Do you remember the incident regarding the realm of the undead? The guy who almost destroyed the whole undead realm and succeeded in doing so for the vampire race is the same guy. Father went to the realm of Undead at that time to take a look and got this portrait.

At that time, he wanted me to investigate it before going to sect, but he doesn't belong to any high-level organization and there was no trace of him, even in the subordinate realms that we have under our control.

It is as if he vanished into thin air. And we still don't know how he entered the realm of the undead. Now it seems like we would find out if we catch him.

I will come back to the family by tomorrow.

Tell uncle not to worry about it and I would be getting some help from my friends."

With that, the attendant left and the young master went to the nearest town.

He entered the most luxurious inn in the town and met with four others who are sitting in the room leisurely.

"Brothers, I need some help."

"Help, is there any problem with construction? Or you just want to take advantage of something and skip your turn in supervision duty?"

"No, the trouble is actually from my family."

This time a guy who is munching on some food looked at him and said.

"Again? Just what kind of a pain in the ass is your family? You need to clear their mess this many times?"

"Well, this time, the mess is a bit complex. The enemy is unknown and there are three possible enemies. We don't know how to proceed with this. I am sure this would be interesting."

"Oh really? What is so interesting about it? Your rival family must have done something shady to get on your nerves."

"Except they are not in the list of suspicious targets."

Then, the young master went on to explain the details.

"Now are you interested?"

"To suspect a young man who you came across more than a decade ago as your suspect, that too a human? What do you think his cultivation level is now?" One of the young men asked and he is a dark elf.

"Who knows? How about we go and take a look. At least it is better than sitting in this boring shit hole looking at the construction all day with nothing better to do."

"But one of us should stay here to make sure the construction goes on properly."

"I will stay."

A young man who is dressed in a cloak and also the person who didn't show any interest in the conversation spoke.

"Well, if you are staying here, it wouldn't be a problem, junior brother. If you make sure there are no mistakes in the construction, then we would make sure to leave a good assessment score for you."

"Thank you, senior brothers."

The young man spoke calmly.

The remaining four people including the Night Demon young master left the realm the next day at dawn.

By the time they reached the Night Demon realm, the family head, and some elders are eagerly waiting for their arrival.

When the group of four entered the hall, all the elders and even the family head bowed their heads a little and said.

"Greetings for the disciples of five great sects."

"Greetings to the Night Demon family head and the Elders." The youngsters didn't bow but only replied in a polite tone.

The family head walked to the eldest young master and hugged him before saying.

"Sorry, Davon. I knew that you are busy with your assignment, but I cannot help but ask for your assistance in this matter.

This time the attacks reached our home ground, but we still don't know about our enemies."

"Don't worry uncle. I will make sure we find the culprit. But before that, give me the information regarding the incidents. The undead energy contamination incident, the blood demon family incident, and the city guard post-explosion.

I want to see if we can find any similarities. Make sure to add every single detail to it, no matter how minute.

I also want the details of the investigators of the blood demon family incident.

My friends will go and check the situation at the explosion area. So, let the guards know."

The family head nodded constantly with every one of Davon's requests.

After that Davon and his friends started their own investigation.

Meanwhile, Kiran got a bit anxious and contacted Sam.

"Someone named Davon came out of nowhere. He brought some friends from the five great sects."

"Five great sects?"

Sam frowned and immediately looked through the list of the organizations in the Wrist screen.

The five great sects are the fourth phase organizations. All five of them form a joint organization, but they are still considered separate organizations.

Sam felt like this would be tricky.

At first, he wanted to directly reveal his identity when it came to deal with the final blow on the Night Demon family, but with the five great sects' disciples involved, things would be a bit problematic.

There are two ways to ensure their safety. One is to find a way to make sure these five people wouldn't be stuck in the crossfires and the other way is to make that there are no traces of Sam and his team left here.
