As the heavy footsteps drew nearer, the air in the cave seemed to freeze. Lin Yu and Su Yao stared tensely at the depths of the cave, tightly gripping their weapons. A huge black shadow gradually emerged. It was a stone monster as massive as a mountain, exuding an ancient and thick aura. Each step it took made the cave tremble slightly.
The stone monster's eyes glowed with a faint green light. It stared at Lin Yu and Su Yao, emitting a low growl as if warning them for intruding into its territory. Lin Yu whispered to Su Yao, "Be careful. This stone monster seems tough to deal with. Try not to anger it." However, the stone monster didn't seem to want to let them go. It raised its huge stone arm and smashed it down fiercely towards Lin Yu and Su Yao.
Lin Yu and Su Yao quickly dodged to the sides. The stone arm hit the ground, instantly sending countless rocks flying. Su Yao cast a water - based spell, and a water dragon rushed towards the stone monster. But when the water dragon hit the stone monster, only some water splashed, and it seemed to have little effect on it. Lin Yu circulated his spiritual power, attaching flames to his sword, and flew towards the stone monster's leg, slashing at it. The sword left only a shallow mark on the stone monster's leg.
The stone monster was enraged. It opened its big mouth, and a powerful suction force came out from it, trying to suck Lin Yu and Su Yao in. Lin Yu and Su Yao held onto the rocks on the cave wall tightly to avoid being sucked in. Just when the situation was critical, Lin Yu suddenly remembered the patterns on the stone wall. One of them seemed to depict how to soothe the stone monster. He quickly looked at the stone monster and noticed a depression on its forehead, which was extremely similar in shape to the fire - attribute spiritual pearl.
An idea flashed through Lin Yu's mind. He took out the fire - attribute spiritual pearl and shouted at the stone monster, "Look what this is!" The stone monster seemed to be attracted by the spiritual pearl. It stopped attacking and stared intently at the spiritual pearl. Lin Yu approached the stone monster cautiously and placed the spiritual pearl in the depression on its forehead. As soon as the spiritual pearl touched the stone monster's forehead, it emitted a soft light, and the aura around the stone monster gradually became calm. It slowly crouched down, no longer posing a threat to Lin Yu and Su Yao.
Lin Yu and Su Yao heaved a sigh of relief. They looked at the words on the stone wall again. After careful study, they found that it was recorded that this mountain range was once the battlefield of an ancient war. The five spiritual pearls were originally the key to sealing a certain powerful and evil force. Now that the spiritual pearls were scattered, the evil force showed signs of revival, which was the reason why various forces were vying for the spiritual pearls. And to completely seal that evil force, apart from gathering the five spiritual pearls, an ancient sword hidden in a mysterious place was also needed.
Lin Yu and Su Yao realized the seriousness of the matter. They decided to leave the cave as soon as possible and continue to search for the other spiritual pearls and the ancient sword. Just as they were about to leave, the stone monster suddenly stood up and blocked their way. Lin Yu and Su Yao were startled, thinking that the stone monster had changed its mind. However, the stone monster turned around and walked towards the depths of the cave, and from time to time, it looked back, motioning for Lin Yu and Su Yao to follow.
Lin Yu and Su Yao hesitated for a moment and finally decided to follow the stone monster. The stone monster led them to a hidden cave. Inside the cave, there were some ancient artifacts and an ancient book emitting a faint glow. Lin Yu walked forward and picked up the ancient book. He found that it recorded the specific location of the earth - attribute spiritual pearl, which was in the depths of the earth's core of Wantu Peak, and it also described in detail the method of entering the earth's core.
Just as Lin Yu and Su Yao were delighted by this significant discovery, a commotion suddenly came from outside the cave. Lin Yu quietly walked to the entrance of the cave to check and found that it was Zhao Ling and Liu Yan leading a group of people searching everywhere for them. Liu Yan said angrily, "Those two must still be around here. If we can't find the spiritual pearl, none of us can go back and report." Zhao Ling said with a gloomy face, "Search carefully. Don't miss any corner!"
Lin Yu returned to the cave and told Su Yao what was going on outside. Su Yao frowned and said, "They keep pestering us. What should we do?" Lin Yu thought for a moment and said, "We should still follow the original plan to go to Wantu Peak to find the earth - attribute spiritual pearl. They are in the open, and we are in the dark. As long as we act carefully, we should be able to avoid them."
So, with the help of the stone monster, Lin Yu and Su Yao left the cave through another hidden passage. They headed towards Wantu Peak, being cautious all the way and constantly on guard against the pursuit of Zhao Ling, Liu Yan, and the others. After several days of traveling, they finally arrived at the foot of Wantu Peak.
Wantu Peak towered into the clouds. The mountain body presented a colorful appearance, and each layer of soil exuded a different aura. Lin Yu and Su Yao found a hidden entrance on the halfway up the mountain according to the method in the ancient book. The entrance was sealed by a thick layer of soil and stones. Lin Yu circulated his spiritual power and, together with Su Yao, pushed aside the soil and stones with their combined strength.
After entering the entrance, there was a narrow passage. The passage was filled with a strong earth - attribute spiritual energy. They walked down the passage, and the deeper they went, the stronger the spiritual energy became. Suddenly, a huge stone chamber appeared in front of the passage. In the center of the stone chamber, there was a stone platform, and on the stone platform, there was a spiritual pearl emitting a yellow light, which was the earth - attribute spiritual pearl.
Just as Lin Yu and Su Yao were about to step forward to take the spiritual pearl, a group of earth puppets suddenly emerged from all around the stone chamber. These earth puppets were tall and held stone axes, charging towards Lin Yu and Su Yao. Lin Yu and Su Yao immediately got into a fighting stance and engaged in a battle with the earth puppets. The earth puppets were powerful, but their movements were relatively slow. Lin Yu used his flexible body skills to constantly dodge the attacks of the earth puppets while looking for opportunities to counter - attack. Su Yao cast spells to create obstacles among the earth puppets to assist Lin Yu.
After a hard battle, Lin Yu and Su Yao finally defeated all the earth puppets. They walked up to the stone platform, and Lin Yu reached out to pick up the earth - attribute spiritual pearl. The moment his hand touched the spiritual pearl, the spiritual pearl suddenly glowed brightly, and a powerful force sent Lin Yu flying. Lin Yu spat out a mouthful of blood, and Su Yao quickly ran over to help him up.
At this time, some words appeared on the wall of the stone chamber: "Those who take the spiritual pearl without permission must undergo a test to prove that they have the ability to protect the spiritual pearl." Lin Yu and Su Yao looked at these words and understood that if they wanted to obtain the earth - attribute spiritual pearl, they had to pass the test.
