Who will not fear when they suddenly appear in a mysterious place? Nevertheless, he suppressed all his fears and asked at the light sparks.

However, there was no reply from the other end.

​​

Nevertheless, Henrick didn't say anything before the light sparks were coming together to form a human silhouette.

Soon, the transparent old man appeared that looked almost similar to the one who tasked him in raising the spirit wolf and spirit fox without fighting each other.

However, there were some minute changes between the two of them.

"Young man, aren't you warned to not enter the sealed cave?"

The old man's face was very serious as he asked Henrick.

"Yes, immortal, but….."

"Idiot."

"Are all the youngsters like this?"

.

.

.

.

Henrick didn't know what to say as he tried to explain something; however, he was brutally interrupted by the curses from the old man.

"Sigh...however, it's not your fault. The fault lies in my little brother's thoughts. I told him to seal the cave properly; however, he only placed a normal boulder."

After scolding Henrick for some time, he started scolding his twin brother.

"A cultivator's curiousness is very difficult to stop. As long as he senses something, unless he finds more about it, he will not leave from that place."

The old man became melancholic as he muttered to himself.

"Okay then….now you have only two options. One, I will kill you and the second option is, you will take the position of the underworld fire dragon to guard the entrance of this world."

"What?"

Henrick was shocked when he heard the old man's words.

He was not shocked because of the first option or the second option, he was shocked when he heard the 'Entrance of this world'.

Entrance of the world, as its name suggests, is the door to enter into their current world, Aecrath.

"That's right! You will become the guardian of this gate and kill anyone that tries to enter through this gate."

While Henrick was shocked by the old man's words, the old man continued and asked him, "Select an option soon."

"I can choose the second option but as you can see I am not strong enough to guard the gate."

Henrick doesn't need to hide his cultivation in front of an immortal cultivator and at the same time, he suggested, "Why don't you pick a strong cultivator to guard the entrance?"

Instead of giving such a huge mission to an energy condensation realm cultivator, it should be given to the cultivators in the grandmaster realm.

"Okay then...I will kill you and pick a strong cultivator,"

Henrick became happy when he heard the old man's starting words; however, he became anxious with his later words.

"I will choose the second option...I will choose the second option."

When he saw the serious expression on the old man's face, Henrick didn't think much as he hurriedly selected the second option.

"That's better."

The old man revealed a satisfied expression on his face after Henrick selected the second option.

'Phew'

Henrick heaved a sigh of relief when the pressure from the old man disappeared.

"Don't worry. The invaders from the other worlds will only send cultivators that have the strength below the immortal world. As for the master and grandmaster realm invaders, I will place a barrier which will stop them from entering this world for at most 6 months; however, I am not sure whether it will last for that long."

"So, you have to guard the gate and at the same time increase your cultivation as soon as possible."

The old man knew that Henrick is still not powerful enough to fight the master realm and above cultivators. So, he decided to use the immortal essence to form a barrier for six months.

"Respected immortal, why don't you form a barrier for everyone? So that, there is no need for anyone to guard this gate,"

Henrick has the confidence to kill some from lower levels of the energy transformation realm; however, for others, he didn't have enough confidence to kill.

Moreover, if he guards the gate, then who will cultivate and become immortal?

"Good idea."

To Henrick's surprise, the old man nodded his head and before Henrick could thank him, the old man said, "So, I really don't need your help then, right? I will kill you then."

While saying that, the old man once again released his immortal pressure that suffocated Henrick.

"No no no...I will become the guardian of this world and protect it from the otherworldly invaders,"

Henrick gritted his teeth as he swore in front of the immortal cultivator.

"Young man, you are interesting. I hope you keep your word; otherwise, I have thousands of ways to torture you and crush your soul ten thousand times."

After saying that, the old man silently thought in his head, 'I have to use my immortal essence to maintain the barrier. So, at most I can help you with a simple barrier that can stop the grandmaster and master realm cultivators.'

It was not the old man's intention to not keep a full barrier for otherworldly invaders to not come into this world. But the consumption of the immortal essence is too much and if he continues to use the immortal essence, his cultivation will diminish with time.

As for why he can't ask the strongest cultivators of the world to guard the gate, only the immortal cultivator knows.

"I will do as you say, respected immortal," Henrick bitterly nodded his head.

"Don't give me that bitter look. You killed the old guardian and now you have to take its place."

Seeing the bitter look on Henrick's face, the old man scoffed and continued to say, "Also, each time you kill the otherworld invaders, you will get their possessions which will help you increase your cultivation and not to mention the mid-level energy crystal. It will continuously absorb the fire elements from outer space and give you pure fire elements. So reaching the master realm in the next six months is not a big problem for you."

"Now, I am going. Try your best to guard the gate."

After finishing his words, the old man disappeared and at the same time, he returned to his body.

"Henrick….Henrick."

"What happened to you."

For the entire time, Henrick has frozen making Nick and Lina worried.

'Ding,

Mission:- 'Explore the cave' is completed.

'Ding,

A special flame crystal has been sent to the master's inventory. Please break it to receive the special flame.

Just as he returned to his body, he heard the anxious voices of Lina and Nick. At the same, he received the system notifications which informed him about the mission completion and the reward.

"I am alright," Henrick replied to Nick and Lina with a bitter smile on his face.

He thought that he is the king in this treasure land; however, he didn't expect that he would become the prison that guards the entrance of the world.

"Thank god, you are okay."

Nick heaved a sigh of relief and suggested, "Since we have collected all treasure and got an energy crystal, shall we leave this place now?"

When he heard those words, Henrick became even more depressed.
