Lin Yu and Su Yao were on high alert, watching the approaching black - armored warriors. They understood each other's thoughts without words. Lin Yu held the ancient sword horizontally in front of him, the sharp sword qi spreading out. Su Yao quickly formed seals with her hands, ready to release a powerful spell.
The black - armored warriors made the first move. The warriors in the front row suddenly accelerated, shooting towards Lin Yu and Su Yao like black arrows. Lin Yu didn't flinch. He held his sword to meet them. The sword shone with light and instantly clashed with the warriors' weapons. The sounds of "clang, clang, clang" rang out continuously, and sparks flew everywhere. Su Yao seized the right moment and launched an Ice Prism Spell from the side. The ice prisms, like sharp blades, penetrated the armor of several black - armored warriors, causing their movements to falter.
However, there were a large number of black - armored warriors, and they were fearless of death. The warriors behind stepped on their comrades' bodies and continued to attack. Lin Yu's swordsmanship was in full play. He fought fast with speed, and for a while, the black - armored warriors found it difficult to break through his defense. But Lin Yu knew that this couldn't last long. As he fought, he searched for flaws in the black - armored warriors' formation.
Su Yao kept casting spells from the rear to support him, but the black - armored warriors seemed endless, wave after wave. Suddenly, Lin Yu noticed that every time the black - armored warriors charged, the left - rear of their formation would loosen slightly. He seized the opportunity and suddenly exerted force, sending a flaming sword qi slashing towards the left - rear of the black - armored warriors. This strike was extremely powerful and directly tore open a gap.
Lin Yu shouted, "Su Yao, follow me closely!" The two rushed out through the gap and ran towards the hidden door. The black - armored warriors reacted quickly, turned around, and gave chase. Their footsteps shook the ground.
Lin Yu and Su Yao reached the door. Lin Yu reached out and pushed hard. The door slowly opened. Behind the door was a narrow passage filled with a soft white light. Without hesitation, the two rushed into the passage and turned back to close the door to block the black - armored warriors. But the black - armored warriors were too fast. A hand had already reached in and got stuck in the crack of the door.
Seeing this, Lin Yu swung his sword at the hand. The sword was extremely sharp and directly cut off the hand. The black - armored warrior groaned in pain. Lin Yu took the opportunity to push the door hard. With a loud "boom", the door finally closed, blocking the black - armored warriors outside.
Leaning against the door, the two gasped for breath. After a while, they regained their senses and began to look around the passage. The walls of the passage were engraved with various strange patterns, seemingly telling an ancient history. Lin Yu and Su Yao walked along the passage and found that the patterns gradually became clearer, telling of a great battle in ancient times. The five spiritual pearls and the ancient sword were originally sacred objects used to seal the source of evil. Later, the power of the source of evil leaked out, and the spiritual pearls and the sword were scattered all over the place. Now, if they want to completely seal the evil, they must gather the five spiritual pearls and the sword and perform a special ritual.
Continuing deeper along the passage, a huge stone platform appeared at the end. On the stone platform, there was a glowing ancient book. Next to the ancient book was a spiritual pearl emitting a cyan light, exactly the wood - attribute spiritual pearl they had been looking for.
Lin Yu and Su Yao walked forward. Lin Yu picked up the ancient book and found that it recorded more details about the sealing ritual and the possible whereabouts of the other spiritual pearls. Just as Lin Yu was about to open the ancient book to study it carefully, suddenly, a violent came from outside the passage. It seemed that the black - armored warriors were trying to break through the door. At this time, Lin Yu and Su Yao hadn't fully understood the secrets in the ancient book. Although they had obtained the wood - attribute spiritual pearl, there was still a long way to go before gathering all five spiritual pearls and completing the sealing ritual. Once the black - armored warriors outside the passage broke through the door, they would be in crisis again...
