In the castle hall, the skin above the red dragon's eyelids gathered slightly in the middle. He found that the four-dimensional attribute did not increase after he became a dragon, but a dragon breath skill changed from gray to usable.

"If the dragon is so weak, why should the other party become a dragon and fight with me? According to the theory that the Dragon slaughtering warrior will eventually become a dragon, if he is also a warrior, it will be more convenient to recover his body and fight with me!" Gray wondered.

In fact, becoming a dragon has attribute bonus, but gray has just absorbed dragon blood and has not fully absorbed it, so there is no attribute bonus for the time being.

Moreover, after becoming a dragon, ordinary people will be affected by evil thoughts and prefer to exist in the form of a dragon. Most of the time, they will not become human. Even if they become human, they will not last long. They will soon be affected by evil thoughts and become a dragon.

These are the information gray didn't get from the dragon's spiritual body, so he doesn't know yet.

"Dragon breath!" Gray read in his heart, opened his mouth and breathed out.

"Fortunately, it's much better than that little turkey. If I become a dragon, no brave man can brush me!" Gray smiled proudly.

After determining that he could become a dragon, gray did not continue to experiment, but changed back to a human body, took out a suit from his backpack and put it on.

The previous clothes broke when they became dragons. Fortunately, the system brought a one cubic meter space backpack, otherwise he would run naked now.

After making sure there was nothing wrong with him, gray rushed to the tallest room in the castle. The room was locked. He could feel the slight breath coming from it.

There will be no second person in the castle, so it must be the princess.

Having determined this, gray split the iron lock on the door with a sword, pushed the door open and went in.

"Who are you?" A timid voice sounded. Gray saw that the princess was hiding in the corner with a trace of fear in her eyes.

"Princess, don't be afraid. My name is gray. I'm the captain of the Royal Guard. I'm here to save you!" Gray walked over with a gentle smile. "The dragon has been killed by me. Princess, you're all right. I'll take you back to your majesty!"

"OK, thank you. I'll let my father reward you when I go back!" A smile appeared on the princess's face when she heard the speech, but a trace of fear in her eyes could not escape Gray's eyes.

He knew that after his spiritual strength reached 20 points, he not only improved his control over himself, but also became more sensitive to many things.

He could vaguely perceive the emotional changes of the princess. The other party was afraid when he came in. Even if he explained his identity and purpose, he didn't improve much.

Although confused, gray didn't ask. As long as the princess followed her back, as long as she got the reward she deserved, it wouldn't matter if she didn't want the princess.

And knowing that the dragon can change into an adult, he doesn't think much about the princess. Think about it. If it can't become a human, what can the Dragon do to catch the princess for appreciation?

Hum, I'll do such a boring thing!

"Princess, let's go. The king and queen have been worried about you for years. They will be very happy if you can go back!"

Gray's gentleman stretched out his hand and asked her royal highness to leave the castle.

As far as he knows, the princess was caught by the Dragon at the age of 12. Now it has been ten years. Countless brave people set out, and only one of them succeeded.

"OK, please go ahead and lead the way!" Said the princess.

Gray nodded and took the lead out of the room. "Let's go back now. We can return to the capital at noon tomorrow, but don't worry, princess. I'll protect you."

But before going out, gray looked at the princess's room. There were two windows in it. One could see the scenery outside the castle, and the other looked where?

"Of course, you are a great warrior. You can kill even the dragon. What enemy will be your opponent!" The princess complimented in the rear.

They walked a distance down the stairs. Gray suddenly stopped, his nose stirred a few times, and his eyes brightened. "The smell of treasure!"

In both eastern and Western legends, dragons love treasures. The Dragon Palace in the East has many treasures, and the Western dragons also like to move the treasures back to their nests.

After gray found that he could become a dragon, he became more sensitive to the treasures around him.

"Princess, wait a minute. I'll be back in a minute!" Gray's eyes turned and asked the princess to wait and walk to the end of the corridor.

What he didn't find was that when he left, the fear in the princess's eyes was almost turned into reality.

After looking back and finding that he couldn't see the princess, gray kicked open the door of a room and sniffed at the door. Gray went straight to the two big boxes in the room.

The box is not locked. It seems that Mr. dragon often comes here to play with his treasures and is quite confident in his strength.

One box is full of gold coins, and the other is some treasures such as gold, precious stones and pearls.

"Rich!"

Gray got excited, took out twelve gold coins from his backpack, threw them into the box, and couldn't wait to put them into his backpack.

Although he also had an impulse to play with these treasures, it was not too strong, and he could restrain it without this time.

However, he packed a lot of things in the backpack space and couldn't fit the two boxes. He had to take out some unused things and throw them away.

"If I had known, I would have left some achievements and upgraded my backpack!"

Yes, achievement points can also be used to upgrade backpacks. One achievement point is equal to one cubic space, and two cubes are enough to hold these things.

But let's think about it. In such an emergency before, how can we leave attribute points? It's a joke about his life. He won't do such a stupid thing.

"Ha ha, killing monsters and losing treasure is really the right way!" A wave of fat gray sighed and hurried back to his original position.

If anything happens to the princess, she will lose a bigger treasure.

Back to the stairs, Gray was relieved to find the princess still there.

"Did you find anything?" The princess disguised her emotions and asked with a smile.

"Nothing, let's leave now!" Gray didn't mean to say the treasure. It's second to take a share. It's mainly because the space backpack is hard to explain.

The princess nodded slightly, did not continue to ask, and silently followed gray away.

After passing the castle hall, Gray's eyes were cold. The original dragon body was gone, leaving only a pair of human bones.

"Is the power of the Dragon sucked away by me, or will it return to its original shape after death?"

Gray was puzzled, but did not show it. He just went to the location of the original dragon head and picked up a dragon tooth.

In this castle, this dragon tooth is still an object on the dragon, and most of the others have changed back to human appearance.

"What is this?" The princess wondered.

"It's estimated that it's the warrior who came to save the princess before. It seems that he hasn't hit the dragon and died here. It's a pity!" Gray shook his head.

"Then let's go. I always feel a little scared looking at this!"

After a moment of silence, Gray said, "don't worry. He died to save the princess. No matter what the result is, he once had a heart to save the princess. Let's bury him. Don't let him die and have no home!"

"All right!" The princess nodded reluctantly.

Gray picked up his torn clothes, wrapped the bones, took them outside the castle, dug a hole and buried them.

The princess looked at gray and said nothing. She looked inexplicable.
