Qin Hai followed suit and jumped down from the hole. The brown bear landed on the ground, creating a hole in the ground. It lay there motionlessly, looking like it had suffered a heavy fall.

In the natural world, brown bears were more powerful than tigers. Their most powerful weapons were their thick paws and sharp teeth. If they attacked with their full strength, they would be able to bite off more than 800 kilograms. Therefore, if an ordinary person were to be hit by their powerful bear paws, it would be normal for them to have a few broken bones. However, if they were to be bitten by their teeth, there was absolutely no chance of survival.

This brown bear was clearly no ordinary beast. Not only was it more muscular than any brown bear Qin Hai had ever seen, it was also very agile. More importantly, this beast was very smart. It even knew how to lure enemies by feigning death.

At this critical moment, Qin Hai instinctively tilted his head to the side, and the brown bear's sharp fangs tore a big hole in the ground.

Bang! Bang! Bang!

The brown bear was known for its coa.r.s.e skin and thick flesh. It was much stronger than the average brown bear. Its fur was tougher and thicker, and its fur was thicker and harder as well.

The brown bear, weighing more than a ton, flew backward and crashed into the wall like a knocked tank. The wall that had already rotted away a long time ago fell as the brown bear hit it, creating a huge hole. Countless pieces of debris fell to the ground and formed a small hill, burying the brown bear inside.

Not long after that, the brown bear howled from beneath the pile of rubble, and the mountain-like pile of rubble was suddenly lifted. Amidst the dust, the brown bear shook off the fat on its body. Countless rocks flew in all directions. It stared at the sea of Qin, blood continuously dripping from its mouth.

Although the brown bear was injured, it had become even more dangerous because it had been thoroughly enraged.

Suddenly, the brown bear leaped out of the rubble and rushed toward Qin Hai with nimble steps that didn't match its huge, fat body.

The moment it landed, the entire castle seemed to shake.

Qin Hai did not move as he slowly clenched his fists. Just as the brown bear was about to reach him, Qin Hai suddenly ran towards it.

He was much faster than the brown bear. In the blink of an eye, Qin Hai appeared in front of it and punched it in the forehead.

This punch was different from the three punches earlier. Qin Hai had already used his primeval essence, and other than the nose bone shattering on the spot, all the internal organs of the brown bear were instantly disintegrated by the true essence that penetrated its body.

The brown bear's fat body fell down heavily. Its eyes were still fixed on Qin Hai, but it soon lost its spirit. Blood flowed out from its big mouth …

The castle was silent. Except for the echo, there was no other movement.

Qin Hai shouted a few times, but there was still no sound from his surroundings. Qin Hai frowned.

He studied the brown bear on the ground. If he was not mistaken, it was exactly the same as the one the photographer had inadvertently photographed.

However, when he released the Mortal King Realm, he did not discover anyone. Even Amy and the others had disappeared.

"You're not coming out? I'll tear down this castle and see if you can come out!"

After Qin Hai finished speaking, he immediately took out the Ice Soul Sword. A few sword Qis shot out and the ancient castle quickly turned into a mess.

Not long after, the first floor of the castle was riddled with holes. However, the mysterious person hidden in the dark had yet to appear.

At this time, Qin Hai also realized something strange. No matter how much strength he used, the external wall of the castle remained unharmed. Even if he used his greatest strength to attack the outermost layer of the wall, he could not shake it. In other words, no matter how much he tried to tear down the castle it was still indestructible.

When Qin Hai got closer and observed more carefully, he found that the outermost walls of the castle had many diagrams, many of which were even carved into the walls of the castle in the form of hollow carvings.

These patterns looked like ordinary decorations, but Qin Hai acutely discovered that these patterns seemed to form a large defensive formation. No matter how hard he tried to hit any part of the wall, this formation was able to evenly disperse all of the power, to the point that no matter how hard he tried to hit the wall, he couldn't break through it.

When Qin Hai opened his eyes again, he found that the castle that had been reduced to ruins had changed back to how it looked when he came in. He was also still standing on the stairs of the third floor, as if everything that had just happened was just a dream.

Qin Hai chuckled as a black box suddenly appeared in his hand. This was a C4 bomb with incredible power. It was prepared before he entered the Green Luan World. He originally thought that he would be able to use it within the Green Luan World, but in the end, he never did.

Qin Hai returned to the first floor of the castle. The place had returned to its original state. Even the brown bear had disappeared. He went straight to the inner wall of the castle and found that the wall was smooth and flat, and all the diagrams he had seen earlier had disappeared.

"Since you want to play, then I'll play to your heart's content!"

With a loud boom, the entire first floor of the castle was instantly razed to the ground.

However, at this moment, the walls of the castle once again flashed with white light, and the gate of the castle suddenly opened. A powerful force pushed Qin Hai out along with the smoke and fire.
