With the defeat of the evil alien forces, the vast universe ushered in a precious dawn of peace. Su Yao and the Allied Fleet returned to Earth in triumph, their return met with a warm welcome and the admiration of all humankind.

Earth, a planet that once struggled in a post-apocalyptic world of extreme heat, has been completely transformed. Cities now boast buildings that blend Earth's technology with that of extraterrestrials. These structures are not only aesthetically pleasing but also possess powerful functionalities. They can automatically regulate their internal environment, utilize quantum energy for stable power, and are equipped with advanced defense and purification systems, ensuring that residents live in safe, comfortable, and environmentally friendly spaces.

Those with supernatural abilities have become guardians and role models of the new era. Under the tutelage of the Global Supernatural Ability Alliance Academy, their abilities have been more finely categorized and studied in greater depth. The academy offers specialized courses on supernatural abilities culture, tracing their origins and development, and exploring their mysterious connection to cosmic energy. Based on their own strengths and interests, those with supernatural abilities choose different development paths, such as combat, support, and exploration, contributing to various fields of human society.

In the realm of science and technology, cooperation between Earth and friendly extraterrestrial civilizations continues to deepen. Joint research teams have achieved significant breakthroughs in multiple fields, including quantum physics, genetic engineering, and interstellar communication. New theories in quantum physics provide a more solid foundation for faster-than-light travel, making interstellar travel no longer a distant dream; advancements in genetic engineering enable humans to better adapt to the cosmic environment and even endow humans with some special abilities previously possessed only by extraterrestrial life; and innovations in interstellar communication technology have enabled real-time information exchange between Earth and distant planets, building a more convenient bridge for cross-civilizational cooperation.

Su Yao did not linger in the joy of victory for long. She knew that peace needed to be maintained and the development of civilization needed guidance. Therefore, she advocated for the establishment of the Universal Peace Alliance, inviting friendly civilizations to join. This alliance aimed to maintain universal peace and stability and promote the common progress of civilizations through diplomatic consultation, resource sharing, and cultural exchange.

Within the framework of the Cosmic Peace Alliance, Earth has welcomed waves of extraterrestrial visitors. These visitors bring with them distinctive products, artistic performances, and technological achievements from their respective civilizations. Museums on Earth host various exhibitions on extraterrestrial civilizations, allowing humanity to experience the diversity of cosmic cultures up close; theaters stage spectacular performances that blend Earth and extraterrestrial elements, with music, dance, and drama finding new vitality in the collision of civilizations; and at science and technology exhibitions, displays of extraterrestrial technology inspire innovative thinking among Earth scientists, propelling Earth's technology forward.

Meanwhile, Earth also sent its own envoys to other civilized planets. These envoys bore the important responsibility of spreading Earth's culture, sharing Earth's experiences, and establishing friendly relations. They brought Earth's music, paintings, and literary works, allowing extraterrestrial civilizations to understand the emotions and wisdom of humankind; they shared Earth's experiences and lessons learned in coping with the high-temperature apocalypse, providing other civilizations with reference models for dealing with crises; and they established trade cooperation relationships with extraterrestrial civilizations, promoting the optimal allocation of resources and common economic prosperity.

However, peaceful development is not without its challenges. Unknown dangers and challenges still exist in the universe. Some mysterious cosmic phenomena, such as spacetime turbulence and dark matter storms, threaten the safety of interstellar travel; and some civilizations have encountered internal conflicts and external pressures during their development, requiring the mediation and assistance of the alliance.

Su Yao once again stepped forward, leading the elite team of the Cosmic Peace Alliance in advanced exploration spaceships on a new journey to explore the mysteries of the universe and resolve the crisis facing civilization. Utilizing Earth's supernatural technology and the wisdom of extraterrestrial civilizations, they bravely faced one unknown challenge after another, writing a new chapter for cosmic peace and the development of civilization. In this new era of the universe, full of hope and challenges, Earth's civilization, under the guidance of heroes like Su Yao, will continue to work hand in hand with many friendly civilizations, striving towards a brighter and more glorious future.
