The genius who counterattacked the mainland

After successfully defeating the Shadow Alliance, the Cosmic Alliance ushered in a period of relative peace. Xu Tiancai and his companions were able to rest for a while, but they knew that the mysteries of the universe were endless and new adventures could come at any time.

Sure enough, during a routine interstellar exploration mission, the Alliance's probe detected a mysterious signal. This signal, originating from a distant galaxy, had a frequency and pattern completely different from any previously encountered signal. Xu Tiancai and his colleagues immediately became intrigued and volunteered to lead an expedition to investigate.

After a lengthy interstellar voyage, they finally reached their target galaxy. This galaxy was filled with a variety of bizarre celestial bodies and energy phenomena, leaving the team members marveling at the wonders of the universe. Following a signal, they arrived at a desolate planet.

The planet's surface, covered in craters and ancient mountains, appeared lifeless. However, as they explored deeper, they discovered a massive structure hidden in a valley. Constructed of an unknown metal, its surface was engraved with intricate runes and patterns, exuding a mysterious aura.

"What is this place? It looks like an ancient relic." Su Yao asked curiously.

Xu Tiancai walked forward and carefully observed the runes on the building. "These runes seem to contain powerful energy, and I feel that they are familiar, as if I have seen them somewhere."

Alice closed her eyes and used her magical perception. "I can sense a powerful magical fluctuation here, but it's different from the magic we're familiar with, more ancient and mysterious."

Lin took out her equipment and scanned and analyzed the building. "According to the instruments, this building is extremely ancient, at least millions of years old. Furthermore, its structure is extremely complex, and it may contain many unknown dangers and secrets."

Xu Tiancai nodded. "No matter what, now that we're here, we have to find out the secrets of this ruin. Everyone, be careful, let's go in and take a look."

They cautiously entered the ruins. Upon entering, an air of antiquity washed over them. Glowing crystals inlaid on the walls illuminated the dimly lit passage. Strange statues lined the passage. These statues varied in form, some resembling humans, others resembling alien creatures, yet all possessed a mysterious beauty.

As they advanced along the passage, they encountered forks in the road and traps. Xu Tiancai, with his wisdom and experience, led his team through peril time and again. While passing through a narrow passage, a barrage of laser beams suddenly erupted from the walls on either side. Xu Tiancai reacted quickly, casting a defensive spell to block the lasers. At the same time, he observed the flickering of distinctive runes on the walls, seemingly related to the activation of traps.

"Lin, look at these runes. Can you find a way to shut down the mechanism?" Xu Tiancai shouted.

Lin immediately stepped forward and carefully studied the runes. After some effort, she finally found the pattern and successfully shut down the mechanism.

"Okay, let's keep moving forward," said Xu Tiancai.

They continued to explore the ruins until they arrived at a vast hall. In the center of the hall sat a circular platform, upon which rested a crystal ball emitting a blue glow. Surrounding the crystal ball was a complex circle of runes, giving it a mysterious appearance.

"This crystal ball must be the key to this relic." Xu Tiancai said.

He walked forward, wanting to examine the crystal ball more closely. But as he approached, the crystal ball suddenly emitted a powerful light, illuminating the entire hall. Simultaneously, a powerful energy surged from the crystal ball, impacting Xu Tiancai and the others.

Xu Tiancai quickly cast a spell to resist the energy shockwave. "Everyone, be careful! This crystal ball seems to contain enormous energy. We must not act rashly."

Alice also felt the powerful force of the crystal ball. "I think this crystal ball might be an energy storage device, or some kind of communication tool. We need to find the right way to activate it, and perhaps we can learn the secrets of this relic."

They began to study the crystal ball. Lin tried to scan the crystal ball with an instrument, but the instrument was strongly interfered with and could not work properly. Su Yao searched around the hall for clues to see if there were any clues about the crystal ball.

After some effort, they finally found some patterns and words related to the crystal ball on the wall of the hall. These patterns and words seemed to be an operating guide, but due to the long time, many contents have been blurred.

Xu Tiancai and Alice worked together to decipher the patterns and text. After many attempts and speculations, they finally understood some key information. It turned out that to activate the crystal ball, one needed to touch the runes around it in a specific order.

Xu Tiancai took a deep breath, then carefully touched the runes in the order he had deciphered them. When he touched the last rune, the crystal ball emitted a strong light again. But this time, the light did not strike them, but instead formed a three-dimensional image above the crystal ball.

The image showed an ancient galaxy map, with some unique locations and symbols marked on it. Xu Tiancai and his companions carefully observed the map and discovered that one of the marked locations was exactly their planet.

"This galaxy map must have important significance. Perhaps it is telling us some secrets about this relic or the universe," said Xu Tiancai.

They decided to record the galaxy map and take it back for further research. Just as they were about to leave the hall, they felt the ground shake. Then, cracks began to appear in the hall's walls, and some rocks fell from the ceiling.

"Oh no, this ruin may collapse! Let's get out of here quickly!" Xu Tiancai shouted.

They quickly ran back along the path they had come from. As they fled, rocks and dust continued to fall, making the path extremely dangerous. However, Xu Tiancai and his companions, with their tenacious will and agility, eventually managed to escape the ruins.

When they returned to the spaceship, they all breathed a sigh of relief. Although this expedition was full of dangers, they also gained an important clue - the mysterious galaxy map.

After returning to the Cosmic Alliance headquarters, Xu Tiancai and his colleagues immediately began studying the galaxy map. They joined forces with scientists and historians within the alliance, hoping to uncover the secrets behind the galaxy map.

After a period of effort, they finally made some progress. By analyzing the locations and symbols marked on the galaxy map, they deduced that this might be a distribution map of the legacy of an ancient civilization. This ancient civilization once possessed highly advanced technology and magic in the universe, and their legacy may contain immense power and knowledge.

"If we can find these legacies, it will be of great significance to the development of the Cosmic Alliance," a scientist said excitedly.

Xu Tiancai nodded. "But we also have to be careful. This galaxy map might have attracted the attention of other forces. We can't let this heritage fall into the wrong hands, or the consequences will be disastrous."

To ensure safety, the Alliance decided to send Xu Tiancai to lead the expedition again, following the guidance of the galaxy map, to search for the heritage of these ancient civilizations. This time, they were equipped with more advanced equipment and more powerful firepower to deal with various dangers they might encounter.

The expedition team set out again. Following the markings on the galaxy map, they explored planet by planet. Along the way, they encountered numerous difficulties and challenges. Some planets were extremely harsh, filled with high temperatures, high pressures, and highly toxic gases; others were inhabited by powerful alien creatures, who launched a fierce attack.

But Xu Tiancai and his companions didn't back down. Using their wisdom and courage, they overcame difficulties time and again. On a planet covered in ocean, they discovered a city hidden beneath the sea. Constructed of a transparent material, the city looked magnificent. However, a powerful energy shield surrounded the city, preventing them from entering.

Xu Tiancai and Alice worked together to research the energy shield's structure and principles. After considerable effort, they finally discovered its weakness and successfully cracked it. Upon entering the city, they discovered a treasure trove of ancient technological equipment and documents. Deciphering these documents revealed that this ancient civilization had achieved significant breakthroughs in energy technology and bioengineering.

"If these technologies can be applied to our world, they will greatly improve people's lives," Lin said excitedly.

They organized and documented these technological equipment and documents, preparing to bring them back to the Alliance's scientists for study. As they left the planet, Xu Tiancai felt a surge of emotion. He realized that there were still many unknown civilizations and wisdom in the universe waiting to be explored and discovered. Each adventure gave him a deeper understanding of the mysteries of the universe.

As their expedition continued, they discovered other relics of ancient civilizations. These relics included powerful weapons, advanced magic items, and precious treasures of knowledge. Each discovery brought them great excitement, but also a great sense of responsibility.

However, their actions did not escape the eyes of other forces. An organization called the "Interstellar Predators" learned of their expedition and began to track and attack them. This organization is composed of a group of greedy alien criminals who specialize in robbing various precious resources and artifacts, using any means necessary.

On their way to a planet, Xu Tiancai and his crew were ambushed by interstellar raiders. The enemy ships were numerous and their weapons and equipment were highly advanced. Xu Tiancai immediately commanded his crew to counterattack.

"Su Yao, you lead a team to control the spacecraft's weapon system and suppress the enemy with firepower. Lin, you are responsible for repairing the damaged parts of the spacecraft and ensuring that our spacecraft can operate normally. Alice, you and I will use magic together to resist the enemy's attacks." Xu Tiancai quickly gave the order.

The battle was fierce, with the ships of both sides engaged in a fierce chase and exchange of fire across the starry sky. The blasts of laser cannons and missiles illuminated the entire universe. Xu Tiancai unleashed a variety of powerful spells, repelling the enemy ships again and again. But the interstellar predators refused to accept defeat, launching relentless attacks in an attempt to break through Xu Tiancai and his men's defenses.

At a critical moment, Alice discovered a flaw in the enemy fleet. She immediately informed Xu Tiancai. Xu Tiancai seized the opportunity and unleashed a powerful magical attack, directly hitting the enemy flagship. The flagship was severely damaged, losing its command capability, and the enemy fleet was immediately thrown into chaos.

Xu Tiancai and his companions seized the opportunity to launch a counterattack, completely repelling the interstellar predators. After this battle, they became even more vigilant. They knew they would encounter more dangers and challenges on their quest for the remains of ancient civilizations.

But they were undeterred by the difficulties. They pressed on, driven by a thirst for the unknown and a commitment to cosmic peace, toward their next goal. They believed that with perseverance, they would unlock the secrets of this ancient civilization and make even greater contributions to the development of the universe. And their adventures would leave behind one fascinating chapter after another in the history of the universe...
