In the ice cave, the fire flickered, and Mark and Carl cast long shadows on the ice wall. Mark's breathing gradually calmed down, and his eyes wandered around the ice cave, and finally fixed on a corner of the ice cave. There, some ancient murals looked particularly mysterious under the light of the fire.
Carl noticed Mark's strangeness, walked to Mark and followed his gaze. "Those murals may be a bit old, have you found anything?"
Mark did not answer, he walked to the murals, stretched out his hand and gently touched the lines. The murals depicted some strange creatures and some symbols he had never seen before. They seemed to tell an ancient story, a story about power and control.
"These murals may hide the secret of controlling power." There was a hint of excitement in Mark's voice, "We need to solve these secrets so that I can become stronger."
Carl nodded, and his eyes revealed a hint of seriousness. "These murals may be left by ancient human ancestors, and they may have mastered the method of controlling this power."
Mark and Carl began to observe the murals carefully, and they tried to find some clues from them. Although the lines on the murals are simple, they reveal an ancient and mysterious power. A strong curiosity surged in Mark's heart, and he felt that he was approaching a huge secret.
They found that the symbols on the murals seemed to be an ancient text, and they were arranged in an orderly manner, as if telling some ancient spell. Mark and Carl began to try to interpret these words. They knew that this might be their only chance.
Time passed by minute by minute, and Mark and Carl were immersed in the interpretation of the murals. They forgot about time and hunger. They had only one goal in their hearts, which was to unlock the secrets of the murals.
Mark noticed that the symbols on the murals seemed to be related to celestial bodies, some like the sun, some like the moon, and some like stars. He realized that these symbols might represent some ancient astronomical knowledge.
"Carl, look at these symbols, they seem to be related to celestial bodies." Mark pointed to a sun symbol on the mural, "This symbol may represent the power of the sun."
Carl walked to Mark's side and his eyes swept over the murals. "You're right, these symbols are indeed related to celestial bodies. We need to find the patterns of these symbols so that we can interpret their meaning."
They began to try to connect the symbols on the murals with astronomical phenomena. They found that whenever they touched the symbols related to the sun, the power in Mark's body would become warm and strong; while when they touched the symbols related to the moon, the power became calm and gentle.
Mark and Carl continued to interpret the murals. They found that the symbols on the murals were not only related to celestial bodies, but also to the change of seasons. They realized that these symbols might represent the power of nature, which they controlled and balanced through the change of seasons.
As they interpreted, Mark gradually mastered how to control the power in his body. He found that by touching different symbols, he could guide the power in his body to flow as he wished.
"Carl, I did it." There was a hint of excitement in Mark's voice, "I can control this power."
Carl nodded, and his eyes revealed a hint of relief. "Good, Mark. Now, we need to find a way to transform this power into our weapons."
Mark and Carl began to look for possible weapons in the ice cave. They found some ice blocks in the ice cave, and Mark tried to inject power into the ice blocks. As he injected power, the ice blocks began to glow, and finally formed a sharp ice sword.
"This is our weapon." Mark's voice was firm, "We can use this power to fight against the Rebirth Organization."
