Chapter 146 Black Hole at the Bottom of the Lake

Lu Xiuyuan took a deep breath, as if to concentrate all his strength on it. He carefully placed the precious gunpowder into the water, his eyes as sharp as an eagle, closely watching the gunpowder's every move.

As soon as the gunpowder touched the water, it burned rapidly like a ignited fuse. The flame seemed so weak surrounded by water that it seemed like it could go out at any time. However, surprisingly, the burning speed of this weak flame was extremely stable, like a strange flower blooming at the bottom of the lake.

Then, a deep and shocking explosion suddenly sounded at the bottom of the lake, like thunder, deafening. The huge power of the explosion caused the surrounding water to tremble violently, forming a series of turbulent whirlpools. Lu Xiuyuan finally showed a satisfied smile on his face, and his eyes flashed with excitement. He knew very well what the success of this experiment meant.

He carefully observed the results of the experiment, and was filled with joy. After careful consideration, he suddenly realized: it turned out that this batch of gunpowder actually had its own oxidizer! This amazing discovery completely overturned previous cognition. With this unique property, gunpowder no longer needs to rely on external oxygen to support combustion in an underwater environment. As long as the gunpowder is kept dry, it can successfully burn underwater and cause an explosion.

This unexpected reward gave Lu Xiuyuan unprecedented confidence in the upcoming adventure. He seemed to see a bright road ahead, and all the difficulties and challenges would be solved. With such a powerful force in his hands, he believed that he would be able to overcome all obstacles and achieve his goal.

However, Lu Xiuyuan did not relax at all because of the temporary calm. He knew that the black hole at the bottom of the lake was like a sleeping beast that could wake up at any time and bring unpredictable dangers. Therefore, he had to be fully prepared to deal with any possible emergencies.

Lu Xiuyuan tapped the storage bag on his waist, which was filled with various grenades. These were the precious spoils he had won in previous expeditions. They were extremely powerful and could easily deal with various complex and changing situations. In addition, he also put on the precious Phoenix Red Gold Armor. This armor was not only indestructible, but also had unparalleled defensive capabilities, which could provide him with reliable protection in life-and-death situations.

Meanwhile, Lu Xiuyuan had already started a meticulous investigation and in-depth research. He immersed himself in ancient books, searching for clues about the black hole at the bottom of the lake. After some effort, he finally found some important clues from an incomplete ancient book. According to records, this mysterious black hole seems to be closely related to a shocking war in ancient times. In that extremely tragic battle, countless lives were destroyed, and their resentment and evil spirits entangled and merged with each other, eventually forming this bottomless black hole in front of them. In the depths of this endless darkness, it is said that there is a huge treasure that makes people salivate, but it is also accompanied by endless crises.

After making all the preparations, Lu Xiuyuan embarked on a journey to find Princess Nishang with a resolute and courageous heart. Princess Nishang is the guardian of this vast sea. She is not only beautiful, but also intelligent, wise and brave, and is respected and loved by the tribesmen.

When Lu Xiuyuan told the princess about his great discovery and his careful plan, the princess was overjoyed. She firmly believed that this was undoubtedly a once-in-a-lifetime opportunity, and perhaps she could solve the mystery that had troubled the tribe for a long time. The princess made a prompt decision and decided to take the risk herself and go deep into the black hole at the bottom of the lake to find out what was going on. She knew in her heart that this journey would be full of difficulties and dangers, but as a guardian with a heavy responsibility, she had no choice but to move forward bravely to pursue the truth.

Then, she carefully selected four or five outstanding monks from the mermaid tribe as her companions. These monks were all outstanding in the tribe, all of them were sturdy, muscular, and powerful, and they were obviously experienced experts. Their cultivation had at least reached the foundation-building stage, and they were able to calmly deal with the many dangers in the black hole.

Led by Princess Nishang, the group carefully shuttled through the layers of checkpoints and blockades, and every step was full of tension and expectation. After a long and arduous journey, they finally arrived at the mysterious crack at the bottom of the lake. The water here was surging like a wild horse, and the waves were turbulent, as if they wanted to swallow up all the creatures that dared to approach.

Faced with such a dangerous environment, Princess Nishang and her companions did not retreat. Instead, they relied on each other, and with their rock-hard willpower and unparalleled strength, they approached the crack step by step. When they finally stood on the edge of the crack, a terrifying bottomless abyss appeared before their eyes.

This abyss is like a passage leading to another unknown world. It is bottomless and emits a demonic aura that covers the sky and the sun. This demonic aura is filled with all kinds of negative emotions and resentment, corroding people's hearts like a plague, making people feel cold and terrified.

Before entering the black hole, Princess Nishang took out a bunch of amulets from her bosom with a solemn look, and handed them to everyone one by one, telling them to keep them close to their bodies, so that they could save their lives when they encountered danger. These amulets were carefully made by her with special materials, which could resist the erosion of most evil spirits, but they could only resist for a while and could not be used for a long time. Afterwards, she repeatedly reminded everyone to be extremely alert and not to take it lightly, because what awaited them next would be endless dangers and challenges. Everyone nodded, indicating that they would follow the princess's words.

After making all preparations, the group began to dive slowly and carefully along the edge of the crack. The deeper they went, the denser the evil spirit became, like a giant beast that was ready to devour people, making people shudder. However, they were not frightened by the scene before them. Instead, they held the amulet tightly in their hands, and with strong willpower and unwavering faith, they moved step by step into the depths of darkness.

Finally, after a long and difficult journey, they arrived at the bottom of the black hole. Here, they found an extremely huge stone door. This stone door was dozens of feet high and about three feet wide. It was engraved with many ancient and mysterious runes and patterns, emitting a faint light. Princess Nishang and Lu Xiuyuan smiled at each other when they saw this scene. They knew that they were getting closer and closer to the truth, and this stone door was the entrance to the truth.
