The tail extended from the end of his spine. The upper end was thick and round, the lower end was thin and pointed, and the top was covered with thick dragon scales. In comparison, the scales on the bottom appeared fine and smooth.

“What’s wrong?”

Mu Heng noticed Shi An’s restlessness and asked with a frown.

Shi An’s tail flicked under the quilt uncontrollably. He was slightly startled and quickly pressed it with his hands:

“No…nothing.”

His sensitive tail rubbed against the sheets, causing him to shiver subconsciously.

Mu Heng looked at Shi An.

The teenager buried his head, and from this angle, he could only see a small part of his face. The tips of his ears turned red.

“…”

Mu Heng pursed his lips, looked back very quickly, then turned around and walked out, “Pack up, I’ll pick you up.”

Before leaving, Mu Heng paused slightly, turning his head to glance at Shi An’s bedside table.

The door closed again.

The steady and even footsteps of the man gradually faded away and finally disappeared.

Shi An let out a long sigh of relief. His tense back slowly relaxed, and he slid under the covers.

It was alright, he didn’t expose himself.

Shi An lifted the quilt, reached out and grabbed the extra dragon’s tail behind him, and began to worry.

“How can you shrink back?”

Even in human form, his tail would peek out, and it would even wag itself according to his mood…

It was an extraordinary hindrance!

While thinking about it, Shi An moved his hand up along his tail until he reached the point where the scales and the skin meet.

A jolt of electricity ran through his spine.

Shi An shivered, and his waist immediately sagged.

What, what was going on?

Very strange!

Shi An’s ears were burning hot and red, and he hurriedly released his hands, staring at his tail in disbelief.

This had never happened before!

The black fog quietly stuck its head out, its expression conflicted and hesitant.

As a monster that has been locked in a small box for tens of thousands of years, the only thing it could use to kill time was the codex of the Mu family. It pretty much memorized the entire book. There might be no one in this world that was more familiar with dragons than it.

Although the black fog knew the reason, but… it didn’t dare to say.

Although the number of molting periods of each dragon was different, no matter what kind of dragon it was, the last molting was the most critical.

——Because after the last molt, the dragon would be in heat.

The rarer the race and the more powerful the dragon, the more ferocious the heat would be.

In many legends, dragons were portrayed as lustful, and this was not without basis.

However, due to the peculiarity and rareness of abyss dragons, when the black fog saw Shi An for the first time, it really did not expect that the other party had not passed the fourth molting period and could not be regarded as an adult dragon.

The Mu family’s handwritten codex recorded information about almost all the dragons. The only dragon they didn’t have information on was the abyss dragon.

So the black fog could not be completely sure.

However, it was certain that Shi An was not completely done with the mold.

What he was experiencing now was just a foreshadowing.

After all the energy from the previous dragon molt had been digested and the strength before molting was generally restored, the molting period was officially over.

And by that time, the real heat would come.

Looking at the panic-stricken, dazed young man not far away, the black fog couldn’t help but fall into contemplation.

Although Shi An had been lived for a very long time, but in the previous tens of thousands of years, the other party had no experience in these matters…

More importantly, he was now the last dragon in the world.

How could he find a partner?

——The black fog really didn’t expect that it would worry about a dragon’s marriage one day.

Could this be the power of the civil contract?

The demon insect had no idea how many complicated thoughts had passed through its heart in the short few seconds just now.

It flapped its wings, flew to the bed, and asked suspiciously, “Sir, what’s wrong? Is there something wrong?”

Shi An glanced at his tail with a lingering fear and stuffed it under the sheet.

That strange feeling finally subsided.

Shi An sighed in relief.

But one thing was resolved, and another, more pressing thing was brought back to the front of his mind.

Shi An frowned worriedly and said, “Mu Heng is waiting for me downstairs, but my tail won’t go back…”

Only then did the black fog pull himself back from its thoughts.

It floated out of its little box and said, “My lord, I have an idea!”

The black fog dragged the thick book out again, flipped to one of the pages skillfully, and then poked out a wisp of translucent smoke, pointing to a line of magic spells in it,

“Look at this, I think it should work!”

Fifteen minutes later.

Mu Heng turned his head and looked in the direction of the stairs.

The boy was neatly dressed and walked down, looking much better than before, but for some reason, it seemed that the others’ limbs were stiff and eyes were wandering.

Shi An’s tail still didn’t change back, so he had to wear a pair of low-waisted trousers. His long tail drooped down.

Based on the ancient magic spell recorded in that book, he cast  some blindfolding spells. Based on the current level of human understanding of profound ancient magic, there should be no flaws.
