The second basement floor is a classical circular Colosseum, which is only one-fifth the size of the "Century Arena" of Apocalypse City, but it is also a great feat to complete such a building underground.

"Mr. Austin, long time no see! I'm glad you agreed to my invitation to come to my proud secret base!" Just as Austin looked around, a beam of light fell from the sky, ingeniously using a golden sun-like hue, projected not far from the elevator, the figure reflected was like a hero in the epic story who finally defeated the demon and received the blessing of the gods, listening to the high-pitched but faintly lacking tone, it was the lord of the city of Beiwang - Sauron!

Austin and the others stepped down from the elevator and stood beside Zoro, while the bird quietly disappeared into the darkness.

Sauron was surrounded by only a beautiful young woman holding his arm, a woman of no more than thirty years old, who was as well-maintained as a young girl in her prime, but who inadvertently revealed a charm that was not possessed by a girl who had not experienced the years.

She wore the same uniform as the patrol above, but it was clearly cut, with a lower neckline, a shorter skirt, and a tighter waist, revealing proud curves and beautiful skin in this cold season.

There was no heating on this floor, and the unknown material of the dome insulated the scorching heat of the previous floor, which was already below minus twenty degrees. Zoro gasped for breath as he exuded a trace of source power to maintain the warm environment around the young woman, ensuring that even if she was dressed so coolly, she would not get frostbitten.

"This is my ...... Forget it, one of my ladies, named Kelly, is also my assistant here, and is a good boy to be trusted. Seeing that Austin didn't mean to speak, Sauron raised the topic again.

Austin smiled, and although he felt a little unexpected in his heart about such a scene, he still maintained the necessary humility, after all, he was not ready for a showdown with the other party.

"Miss Kelly is a shrewd and capable person, and she is a blessing to be a good match in life. ”

"yes. If it weren't for her, how could my experiments here have been completed so smoothly? ”

Austin grinned a little awkwardly, he obviously didn't mean it that way, but the rather stubborn old man in front of him still responded to his politeness according to his own understanding.

Fortunately, the woman named Kelly seemed to be used to such situations, and only rolled her eyes secretly, showing a bit of smart playfulness, and did not take such a conversation to heart.

"Lord Zoro, I don't know what you want me to visit? Is this the Colosseum, or are you domesticating some powerful beast that can change the tide of battle?"

"Beast, heh-" Zoro spat disdainfully, "What beast can withstand the war beasts of the Northern Barbarians? If that kind of powerful creature were to charge collectively, even if all the heavy artillery in Beiwang City opened fire collectively, it might not be able to wipe them all out. And this city wall, in the eyes of the war beast, is probably like a papier-mâché. It's a pity...... The War Behemoth hadn't been seen en masse on the battlefield for many years, and at most five had been seen at a time, resulting in heavy losses to one legion. ”

"That's the fortune of the dynasty. You seem to ...... A bit too far?" Austin reminded after a perfunctory remark.

Zoro patted his head, turned his head and said with a smile: "Haha, I'm sorry, I'm a little verbose when I'm old, not as hot as you young people, and now I don't have anyone to talk to, and I can't stop when I see outsiders." In fact, you may not understand this thing based on my introduction alone, so why not go down and experience it yourself?"

Austin looked in the direction of Zoro's finger, and it was the Colosseum below.

"Sir—" Brunei grabbed Austin and shook his head cautiously.

Austin's appearance was a little relaxed, and without a trace, he slapped Brunei's palm that grabbed his sleeve and said, "Since Lord Sauron has been kind to him, then I will be disrespectful." If you refuse, I'm afraid it will be a little ignorant. ”

With that, Austin didn't wait for Sauron's answer, and jumped down to the Colosseum below. To his surprise, his feet were a little dim because there was no light, but the smooth touch gave him the feeling of walking on the ice!

The depth of this secret base is so deep that he would not be surprised if there was a dark river or underground magma underneath, but such smooth ground is extremely rare.

Austin regained his balance and quickly adapted to the environment.

This may be some kind of special material, which was used by Sauron to build this Colosseum, and the dignitaries can always find something that they can't name, and use it in some seemingly absurd places, Austin didn't think much about it, and quickly prepared for battle.
