I Think I Am Overpowered

I can use all dragon-related skills and all sword skills without expending any mana. It's awesome. But then, what will I do with my 500 mana? "Wait a second." I don't have 500 mana but 500k mana. "Whhhaaaattttt!!", I exclaimed with shock. Again, someone from outside shouted, "Sir, I think his brain is damaged; we have to give him a shock to cure him."

Why is my mana that high? Then, a notification popped up, "Your heart has been replaced by a dragon's heart." "As your veins were not suitable for a dragon heart, your veins were also replaced by dragon veins." "Since you now have a dragon heart, your heart can store more mana than a normal person."

After reading this notification, various thoughts are running through my mind. That slowly my entire body will be replaced by a dragon, and I will become a dragon.

The dragon I killed was also a person like me, and his body parts were replaced by dragon parts. As I killed him, he put his curse on me. Let's see if my original heart is in my item pocket.

There was no heart in my pocket, but a new black sword and a red mana stone were present. I first checked the black sword. It was a shadow sword, and I got it as a reward for defeating the chimera. I acquired the red mana stone by killing a dragon.

Again, my mind is telling me that when someone slays me after I turn into a full-fledged dragon, they will also receive the same rewards. "RIP, dragon kid."

Then some people entered my room. Among them, two were doctors, one was a nurse, and the other two were in coats. The doctor asked me, "Do you remember your name?"

I replied, "Yes, doctor. It is Tarun." The doctor replied, "Then we don't have to give you a shock treatment." I was like, 'what!' The people in coats requested the doctor to leave the room for some time. The doctor bowed his head, saying 'understood, sir,' and left the room.

One person came forward and said, "Hello, my name is Victor. I am from the government. As you are on bed rest for 2 days, many things have happened in the world."

"The monsters we saw, and you fought against, came from dungeon breaches. I think you received a notification saying 'you defeated the boss, and the dungeon is cleared.' So you can understand what I am going to say."

"The American government has discovered that holes, which are dungeons, are emerging all around the Earth. If someone doesn't enter them within a certain time, dungeon outbreaks will occur, and it depends on the level of the dungeon."

"The American government has also recognized the levels of the dungeons, grading from 'E to SSS,' and a device to detect the grade of dungeons. Currently, only E-rank dungeons have emerged, but as the level increases, it will become more difficult to defeat the monsters."

"In Japan, the government had made a breakthrough in predicting dungeon locations prior to their emergence, thanks to a newly developed device." Victor painted a vivid picture of the world's response to this crisis.

"Now, I will come to the point. In different countries, various adventurers who fought against the monsters have formed groups, and some have formed guilds."

"They are announcing that they will clear the dungeons if they receive rewards from the government by signing contracts."

"So, our government wants to employ you as an adventurer who will clear dungeons for the government, and the government will pay you on a monthly basis."

"If you want to serve your country, we can discuss the remaining details. What do you say?"

I replied, "I need some time to digest all the things happening now." He replied, "I can understand what you are feeling now. But we have to move forward, and don't worry about your parents; they are safe. Make a quick decision because our country needs you."

Saying this, he left, and the other person who came along with him offered me a phone and said, "If you've made up your mind, then contact me through this phone. Our number is saved in this phone. Thank you for your help."
