After walking for a while, they came to a secret room. In the center of the room was an altar, on which was placed a crystal that was shining with blue light. The crystal emitted strong energy fluctuations, as if it contained endless power.

"This is the source of the energy we're looking for," Strange said, approaching the altar and examining the crystal closely.

Su Chen felt the powerful energy and had a familiar feeling in his heart, "This crystal... seems to have some connection with the energy in my body."

Strange nodded, "It's very possible. Perhaps through this crystal, we can find out the real reason why you traveled through time."

Just as they were about to study the crystal further, the door of the secret room was suddenly pushed open by a powerful force. A group of creatures of various shapes rushed in, with fierce light flashing in their eyes, obviously with ill intentions.

"We have to be careful," Strange whispered, and quickly cast a protective barrier to protect himself and Su Chen.

Those creatures rammed the barrier frantically, making piercing screams. Su Chen held the shield tightly, ready to fight at any time.

"We can't stay here for long," Strange said, "We must find a way to leave as soon as possible."

Su Chen nodded, and scanned the secret room, and soon found a hidden exit. They quickly rushed to the exit, and Strange cast a magic to set up an obstacle behind them, temporarily blocking the pursuit of those creatures.

They ran along the exit and finally came to an open area. It seemed to be an ancient ruin, surrounded by towering stone pillars, which looked extremely spectacular and mysterious.

"We should have gotten rid of them," Su Chen said breathlessly, stopping and looking around.

Strange nodded, his eyes still alert, "But we can't let our guard down. This world hides too many unknown dangers."

The two continued to explore the ruins and finally found a portal in a hidden corner. Strange stretched out his hand, felt the energy fluctuations of the portal, and then turned to Su Chen and said, "This door leads to another universe. We may be able to find more clues there."

Su Chen nodded without hesitation, "Then let's go."

They stepped into the portal and traveled through endless time and space again. When they returned to reality, they found themselves standing in a bustling city with tall buildings and busy traffic, which was in sharp contrast to the previous doomsday world.

"Where are we now?" Su Chen asked, looking around.

Strange carefully sensed the energy fluctuations around him and said, "This seems to be a technologically advanced place.

The two chatted about the mysterious witchcraft that the villain Su Chen cast on the children when he committed a crime last time.

Su Chen and Strange walked through the bustling city and came to a quiet cafe. The environment of the cafe was elegant, and under the soft lights, there was a strong aroma of coffee. The two sat by the window and could see the people walking hurriedly on the street through the window.

Strange ordered a strong latte, while Su Chen chose a light green tea. They sipped their drinks quietly, immersed in their own thoughts.

"The doomsday world you just mentioned is really terrifying," Strange broke the silence, "that crystal seems to be the core of that world."

Su Chen nodded and said thoughtfully: "I can feel the powerful energy contained in that crystal. It seems to have some connection with the energy in my body."

Strange frowned slightly, "This reminds me of the mysterious sorcery you used when you fought the villain before. Where did you learn those abilities?"

Su Chen's eyes were a little confused. He quietly looked at the street scene outside the window. "That was a memory from a long time ago. Before I became an Avenger, I was a lonely wanderer, looking for my place everywhere."

Strange showed a slightly curious expression, "You mean, you learned those witchcrafts by self-study?"

Su Chen nodded, "Yes. I once met a mysterious old man who taught me some knowledge about magic. Although I am not a real wizard, those witchcrafts did help me a lot."

Strange took a sip of coffee and pondered over Su Chen's words, "What is the identity and origin of that old man? Why did he teach you those witchcrafts?"

Su Chen sighed, "That's a mystery, just like the reason why I have traveled to a different world now. I have been looking for the answer, but I still can't find it."

The two fell into silence, thinking about each other's words. Suddenly, Su Chen's eyes fell on a newspaper on a table, which published a headline: "Mysterious energy fluctuations appeared in the center of the city, attracting widespread attention."

"Thank you, if it weren't for your warning, we might have died under the volcano." A young pedestrian said gratefully.

"No need to thank me, we are just doing our duty." Su Chen said with a smile.

Long Guo also nodded, "We just did what we could."

As the pedestrians left, the desert gradually returned to peace. Su Chen and Long Guo stood there, still feeling the tension and thrill they had just experienced. Although they successfully rescued the pedestrians from the disaster, they were not in a relaxed mood.

"Su Chen, your action is too risky!" Long Guo couldn't help but blame.

Su Chen smiled bitterly and shook his head, "Sorry, I just want to rescue them from the threat of the volcano as soon as possible."

"But your actions may seriously affect the timeline and lead to unpredictable consequences!" Long Guo said nervously. He could feel his own heartbeat.

Su Chen took a deep breath. He knew that Long Guo was right. Any changes made in time and space could have a profound impact on the entire timeline and bring unpredictable consequences. He realized that his actions might have been too impulsive and he did not fully consider the consequences.

"I'm sorry, I didn't consider the consequences." Su Chen said in a deep voice, "But I can't just watch those people die under the volcano."

Long Guo looked at Su Chen deeply, and he knew that Su Chen's original intention was good. Although his actions might bring some uncertainty, his kindness and courage were also worthy of respect.

"Okay, it's over." Long Guo patted Su Chen's shoulder gently, "We should now consider what to do next."

Su Chen nodded. He knew that he needed to act more cautiously and not interfere with the development of the timeline easily.
