Standing in front of the huge Demon Tower Gate, looking at the huge fifteen-story tower, Qin Tianyu's face brought a hint of admiration.

The catastrophe that struck this world 115 years ago, the catastrophe appeared, and mankind ushered in a terrible crisis of life and death.

Humans rely on the Demon Tower to survive the cataclysm, improve their strength, and rely on the Demon Tower to open a new chapter, known as the New Era.

It is now the 115th year of the new era, and there are many amazing masters in the human race, who are constantly exploring the worlds in the demon tower and improving their strength.

But for so many years, they have only explored the second world of the Demon Tower, which is equivalent to reaching the second layer of the Demon Tower, and the thirteen floors behind it are still in an unknown state.

Shaking his head, he didn't think about the unknown, but walked towards the demon tower.

The huge teleportation array on the first layer has the function of leading to the first world of the Demon Tower, as long as you awaken and become a professional, people can choose to enter that world, explore, and upgrade.

Striding into the colorful magic array, Qin Tianyu looked at the whispers around him, ignoring the students who were pointing at him, and instead chose to teleport into the first world.

The brilliance flickered, and the scene in front of Qin Tianyu changed rapidly, as if he was in a whirlpool, and in just a moment, Qin Tianyu was already in a small stone house.

This stone house is quite spacious, about fifty square meters in size, there is a large bed in the stone house, a set of wooden tables and chairs, and some living utensils, in the corner of the stone house is a white magic array, that is the passage in and out of the stone house, this stone house has no windows, but it is very bright, and there is no stuffiness, it is very magical.

"Is this my home in the Demon Tower World?" Qin Tianyu muttered.

When they were in school, they had already learned, and when any professional entered the world, they were automatically assigned a stone house, which was so strong that even the most powerful professional could not break it.

And this stone house can only be entered by its owner, and others who want to enter can only enter with the permission of the owner of the stone house.

Putting down the backpack, Qin Tianyu did not leave the stone house immediately, but began to experiment with his ability to change masters, that is, change white cats.

According to the feeling in the dark, Qin Tianyu activated the ability to transform into a white cat, and in an instant, the clothes on his body fell off, his body shrunk, and finally turned into a white cat the size of an ordinary domestic cat.

"Oh my God? Is this the transformation into a white cat? That's too bad, isn't it? Qin Tianyu's changing white cat made a sound from his mouth, and this voice was exactly the same as his own voice, but there was a hint of depression in his voice.

He thought about it for a while, and began to test the strength of this white cat after transforming into a white cat, and after ten minutes, Qin Tianyu returned to his human form and got dressed, and sat on the bed speechlessly.

"Except that it's faster, more sensitive, and has more stamina, it's basically the same as my physical strength, and I even like to sleep lazy." Qin Tianyu said depressedly.

This change of the white cat, completely based on his physique to determine his own strength, and the increase in strength is not large, Qin Tianyu feels that it is about 10% at most, fortunately, the increase in movement speed and shooting speed is a little more, there may be about double the increase, as for the other Qin Tianyu has not been calculated for the time being.

He now somewhat understood why the outside world would say that the Master of Change was an embarrassing profession, and he was a not very powerful transformation white cat, and he couldn't use it in the real world, which was really embarrassing.

Shaking his head, Qin Tianyu took out the mask in his backpack and put it on his face, and threw the extra things in the stone house, only carrying paper and paintbrushes, some food and water, and preparing to leave his stone house.

Walking to the corner of the stone house, Qin Tianyu stood in the white magic array, and in an instant, the scene in front of him changed, and when he reappeared, he had already come to a huge and incomparably luxurious city.

"My God, is this what the main city is called? It's really magnificent. Qin Tianyu looked at this huge and lively main city with some curiosity.

I saw that there were countless shops in all directions of him, selling all kinds of weapons and equipment, or medicines, clothing, and of course, a lot of food and groceries.

However, most of the things in these shops are brought in from the outside world.

The shops are now very lively, with a constant stream of people coming and going, all armed professionals, and they are not from a city, they have come to the main city at random.

Of course, the kind of main city that Qin Tianyu is in now, there are many in this world, and this main city is not the only one.

"It's a pity that in the Demon Tower World, a person will stay here for ten days at most, and if he has enough time, he will be kicked out of this world, and at least rest in the outside world for an hour before he can enter again, it's a pity." Qin Tianyu shook his head and said.

Putting away his thoughts, Qin Tianyu strode towards the outside of the main city, he had already made a plan, and now his level was only level 1, and the upgrade naturally had to start with the level 1 big rooster.

Normally, levels 1-5 belong to the novice reserve, so these areas will be protected by wandering NPCs, and there will be few troubles here, because they cannot be revived by NPCs.

Walking out of the main city of the First World with a mask, Qin Tianyu glanced at the guards at the gate of the main city who were like puppets, and stepped to the level 1 monster area in the east of the main city.

"Giggles!" The big rooster with all the bells and whistles clucked and roamed the meadow, running around from time to time, leisurely.

In this area, there are many professionals similar to Qin Tianyu who are working hard to kill monsters, some of them are holding big swords, some are holding long swords, some are holding bows and arrows, some are holding daggers, and they are wearing thick armor to fight around with these big roosters and kill monsters.

"Huh? Look at the masked guy over there, who came here without any weapons and equipment, isn't this looking for death? This big is very ferocious, and it can be said that it is very difficult. ”

After killing a big rooster, a professional saw Qin Tianyu standing there in ordinary clothes, and looked at it with some amusement.

"yes, yes, do you still wear a mask and think you're amazing? I'm obviously a rookie, haha. Several professionals who considered themselves veterans said mockingly.

Qin Tianyu ignored them, but took out a stack of paper and the paintbrush from the backpack behind him, he glanced at the big rooster running on the grass, and quietly used the paintbrush to lightly touch the paper with the velociraptor drawing.

"Bang!"

The purple mist kept tumbling, like a cloud, and a hideous head loomed in the mist.

"What's that?" A veteran with a big sword shouted in shock.

You must know that because of the world of the Demon Tower, the information exchange between various cities is very timely, so now the information of all professionals is available in each city, and people know all the occupations when they go to school, but the profession that has never appeared in front of them is very incredible.

"How can there be purple smoke? Could it be that this person has been given some kind of new rare profession? A professional with a large knife said in equal shock.
