Fang Jian looked back, only to see that Dangfeng Mountain God and the others had retreated several feet away, looking at him with innocent eyes.

"You..." Fang Jian paused and said, "Who of you will come with me?"

The faces of the Dangfeng Mountain God, the Patrol General, the Division General, the Guardian General, and the demon cultivators changed drastically upon hearing this. Then, the Dangfeng Mountain God said, "Master Hongqing, your cultivation is high, you can just go down..."

Fang Jian was a little surprised and asked, "What's wrong? Are you scared? Is there something underneath?"

Several people shook their heads and said, "No, there is only one entrance to the underground cave below the tiankeng. Inside the cave is the rare treasure, nothing else."

"Then what are you afraid of?" Fang Jian was a little confused.

Dangfeng Mountain God turned his head and said to a demon cultivator beside him, "Fellow Daoist Shi, go and demonstrate this to Master Hongqing."

"Ah? It's me again." The demon cultivator said helplessly, then walked forward and came to Fang Jian and said, "Master Hongqing, please watch carefully."

Then Fang Jian saw the demon cultivator walk to the edge of the sinkhole and suddenly jumped down. Immediately, he heard a strange cry from the bottom of the sinkhole, followed by a flash of water light, and the demon cultivator flew straight out of the sinkhole.

With a loud 'bang', the demon cultivator's body fell hard to the ground. Only ten breaths later, his body was completely frozen and his whole body was quickly wrapped in a layer of solid ice.

"Hurry, hurry, hurry." Dangfeng Mountain God and others hurried forward, picked up the demon cultivator who was frozen into an ice stick, retreated dozens of feet, and quickly used magic power to ignite a pile of elixir fire on the ground, and then roasted the demon cultivator on the fire.

"..." Fang Jian was speechless when he saw this scene.

The Dangfeng Mountain God said to Fang Jian, "Master Hongqing, you can see that the cold air below is not something that those of us who have not yet achieved immortality can withstand."

Fang Jian nodded and said, "I understand. You wait here for me. I'll go down and find out what's going on."

The mountain god Dangfeng quickly stood up and said, "The cold air is very strong down there, Master Hongqing, you must be extra careful."

However, before he could finish his words, Fang Jian had already transformed into a beam of fairy light and flew into the bottom of the tiankeng.

...

As they continued to descend, the cold air around them became more and more intense, and Fang Jian also felt waves of bone-chilling cold.

He immediately used his magical powers to protect his body, but found that the coldness ignored his protective magical light and seeped into his bones.

But Fang Jian didn't care. What can a mere cold air do to me?

"Hiss!" Suddenly, Fang Jian took a deep breath and shuddered again. Then with a "pop", Fang Jian fell to the ground.

But the moment he landed, his legs were trembling from the cold. His knees bent as he landed, and he knelt on the ground with a thump.

Fang Jian's face darkened, and he felt a little embarrassed, but fortunately no one saw him. He quickly reached out and pounded his legs with his fists, then stood up slightly and sat down again.

After sitting down cross-legged, Fang Jian immediately activated the "Xiantian Zhengfa Hunlei Baojuan" and urged the Zichen Leiling Baoshu to release the power of heavenly thunder.

After a loud thunder sounded in Fang Jian's Niwan Palace, a ball of true fire from heavenly thunder instantly burned in Fang Jian's Niwan Palace.

As the Heavenly Thunder True Fire ignited in the Niwan Palace, the cold air in Fang Jian's body was instantly expelled, and the Heavenly Thunder True Fire also built a thunder and fire barrier around Fang Jian, instantly evaporating all the cold air approaching Fang Jian.

Fang Jian stood up, slowly exhaled a breath of cold air, and felt much more comfortable.

He looked around and saw that the sinkhole was dark, damp, and freezing, with very few living creatures.

There is only a cave entrance with a faint glow on the north side of the tiankeng, which must be the entrance to the underground cave.

A fairy light flashed under Fang Jian's feet, and the next moment he had landed at the cave entrance. In an instant, an extremely cold breath rushed out from the cave entrance, extinguishing the lightning and fire barriers around Fang Jian.

Fortunately, the Zichen Thunder Spirit Tree in the Niwan Palace reacted immediately and once again formed a barrier of thunder and fire around Fang Jian, resisting the invasion of the cold air in the cave.

Fang Jian summoned the Taiyi Golden Light Sword and held it in his hand, then stepped into the underground cave.

As soon as he entered the underground cave, Fang Jian felt that it was completely different from the outside. The cave was very vast and there were towering stalactites everywhere.

Moreover, the stalactites were shining with jade-like light and brilliant brilliance, illuminating the entire underground cave.

Fang Jian held the Taiyi Golden Light Sword and gradually entered the depths of the cave. Soon, the "exotic treasure" appeared in Fang Jian's eyes with its dazzling brilliance.
