Stinky tofu, Gui Jianxin, Young Master Yue and the Ouyang father, along with Ouyang Feiying, should have already succeeded in their plans.

The traces of the formation above the Four Corners City faded away. Li Dao's eyes were eager to try. He did not know how much luck the old man had painstakingly prepared for this battle.

With a flick of his finger, the cyan sword aura broke the center of Gui Jianxue's eyebrows. Only then did Li Blade feel at ease.

Otherwise, with Gui Jianxue's current state, he might be able to do something crazy.

"Xing'er, protect the little bean sprout. I have something very important to do right now." Li Dao walked up to Xing'er, gave her a few instructions, and then disappeared.

Shangguan Yan was still comforting Gu Mutian. This was all Li Dao could do for Gu Mutian.

Xing'er looked in the direction where Li Dao had disappeared, whispering a few words to the bean sprout before resolutely chasing after him.

On a dry peak on the west side of the city, Li Dao sneered, "Fringe Old Man, you have been working hard to achieve this, but can this formation stop me?"

Li Dao stood in the open space as if he was talking to himself, but in reality, he wasn't.

The long sword was drawn, and a towering green lotus bloomed, stretching the heavens and earth.

The magnetic field between the heaven and earth was disturbed by the soaring sword energy. The surrounding scenery started to change, and a cliff appeared in front of them.

"This illusion array is really marvelous, but you are still wrong." Li Dao chuckled and stepped into the cave.

Li Dao could not help but click his tongue as he stepped into the cave. There were clearly marks carved into the cave walls. The entire dried up mountain had been hollowed out by someone. The old man at the border must have really put in a lot of effort.

The cave could only allow two people to pass through, meandering down to the underground. In order to avoid traps and arrays, Li Dao carefully groped his way through. It took him a full four hours before he found the old man at the border.

At the same time Li Dao found the old man at the border, Xing'er chased after him to the entrance of the cave.

The air was scorched, without a trace of moisture. In front of him was a sea of molten lava, and above the sea of fire floated an ancient copper cauldron.

The old man had one hand wrapped around the black and white airflow like a little snake, while the other was controlling the copper cauldron, preventing it from falling into the sea of fire.

Needless to say, Li Dao also knew that the black-white Qi in the old man's hand was the yin and yang energy of life and death. However, he did not know what was inside the copper cauldron.

Seeing Li Dao appear, the old man's face became extremely ugly. However, he did not say anything as if they had reached a critical moment.

Clap, clap, clap. The crisp sound of clapping echoed in the underground space. Li Dao's smile became even more brilliant.

"Great fortune, this is great fortune!"

"Borrowing the power of the Core Fire to refine medicine, and not even sparing to arrange such a huge game to refine Yin Qi and Yang Qi … Old Border Elder, just what kind of divine medicine are you refining?"

"I know, you can't be distracted right now. You don't have to answer me, you just have to nod or shake your head." But it was hard not to be happy about it.

The old man's face darkened and beads of sweat appeared on his forehead. It was obvious that he was not in a relaxed state.

"Comrade Frontier, thank you for your hard work. It's just that I don't know if you've ever heard of a saying, 'Hatred compresses gold every year, so you can help others get married, hahahaha!' Li Dao laughed out loud. This feeling was wonderful. It was no wonder that the great villains were like chatterers. They really were joyous and needed to be shared.

The ancient bronze cauldron floated and sank above the sea of fire, and the old man's body emitted a strong killing intent.

Under the sea of fire, the boiling lava bubbled and bubbled.

Li Dao excitedly sized up the old man at the border. He did not know how long this old monster had lived. Martial arts, astrology, medical techniques, formations, divination, pill refining, it was as though there was nothing he did not know.

However, regardless of how scheming the old man was, being forced to the point of exploding was still a huge advantage for him. Thinking of this, Li Dao couldn't help but admire himself.

The lava boiled even faster. In the dark underground, Li Dao and the old man's expression were completely different.
