After leaving the stone forest, Lin Tian's heart was filled with longing and anticipation for the future. His initial exploration of the Spiritual Realm had allowed him to sense its vastness and mystery. However, he understood that the real challenges had just begun. After walking in the Spiritual Realm for several days, Lin Tian accidentally heard a rumor about the Secret Realm of Tianxuan. The Secret Realm of Tianxuan, a name that was extremely renowned in the Spiritual Realm. It was rumored to be an independent space created by an ancient powerful figure, containing countless rare treasures, ancient spells, and even some said that the way to ascend was hidden here. However, the entrance to the Secret Realm of Tianxuan was extremely hidden and only opened once every hundred years. "The Secret Realm of Tianxuan..." Lin Tian murmured this name, his heart stirring. He knew that such a secret realm was not something that ordinary cultivators could enter. But at the same time, he also felt an uncontrollable desire - a desire to seek more powerful forces in this secret realm. However, Lin Tian quickly calmed down. He understood that although the rumors of the Secret Realm of Tianxuan were attractive, entering it was no easy task. First, he needed to figure out the specific location of the secret realm. Secondly, he also had to find the way to enter. For this, he decided to search for those cultivators in the Spiritual Realm who might know the secrets of the Secret Realm of Tianxuan, attempting to obtain more information from them. After some investigation, Lin Tian learned that there was an ancient cultivation family in the Spiritual Realm - the Xuantian Ancient Clan. This family had been closely related to the Secret Realm of Tianxuan since ancient times. The Xuantian Ancient Clan held a prominent position in the Spiritual Realm, with countless powerful cultivators in the clan. It was rumored that the clan held an ancient map of the Secret Realm of Tianxuan, which could guide cultivators to find the entrance of the secret realm. However, it was not easy to get in touch with the Xuantian Ancient Clan. This family was extremely exclusive, rarely interacting with external cultivators and not easily revealing the secrets of the Secret Realm of Tianxuan. Lin Tian understood in his heart that to obtain that map, he must find a way to infiltrate the Xuantian Ancient Clan. After some thinking, Lin Tian decided to head to Xuantian City where the Xuantian Ancient Clan was located. He hoped that through his efforts, he could win the trust of the Xuantian Ancient Clan and thereby obtain more information about the Secret Realm of Tianxuan. On the way to Xuantian City, Lin Tian encountered some troubles. Although the cultivators and spirit beasts in the Spiritual Realm fought independently, there were often some disputes. Once, he was besieged by several evil cultivators on the road. These cultivators eyed Lin Tian's magical artifacts and storage bag, wanting to rob him of everything. Facing their attacks, Lin Tian was not panicked. He responded calmly, using the spiritual skill "Spiritual Light Transformation Shadow" learned from the stone tablet to instantly evade the siege of the enemies. Then, he sacrificed "Dark Nether True Fire" and directly burned one of the cultivators to ashes. Seeing this, the others were immediately terrified and fled in all directions. After dealing with these evil cultivators, Lin Tian continued on his way to Xuantian City. He knew that in the Spiritual Realm, strength was the fundamental for survival. Without strong strength, it would be impossible to gain a foothold in this dangerous land. Xuantian City, an extremely ancient and prosperous city in the Spiritual Realm, was crowded with cultivators and lined with shops. It was one of the most important trading centers in the Spiritual Realm. After arriving in Xuantian City, Lin Tian found that the cultivation atmosphere here was extremely intense. The spiritual energy in the city was more concentrated than in other places, obviously due to the large number of spirit-gathering arrays set up in the city. Lin Tian inquired around in the city, trying to find clues related to the Xuantian Ancient Clan. He found that although the Xuantian Ancient Clan held a prominent position in the city, they were extremely low-key and rarely showed up in public. Only a very few cultivators could have contact with them. Lin Tian thought secretly in his heart and decided to approach the Xuantian Ancient Clan in a low-key manner. One day, when Lin Tian was looking for some materials needed for cultivation in a Lingbao Pavilion in the city, he accidentally heard several cultivators talking about a recent secret art competition held by the Xuantian Ancient Clan. It was rumored that this competition was set up by the Xuantian Ancient Clan to select outstanding cultivators. The winner would have the opportunity to gain the favor of the Xuantian Ancient Clan and might even be recommended to cultivate in the clan. "This is exactly an opportunity!" Lin Tian secretly rejoiced in his heart. He knew that if he could stand out in this competition, he would have the opportunity to come into contact with the Xuantian Ancient Clan and might even obtain the secrets of the Secret Realm of Tianxuan from it. However, Lin Tian also understood that this competition would surely be filled with experts and the competition would be fierce. Without sufficient strength, it would be very difficult to gain a foothold in it. Therefore, he decided to enhance his cultivation before the competition to ensure that he could achieve good results in the competition. In order to improve his strength, Lin Tian bought some rare spirit grasses and pills in Xuantian City. These resources were extremely scarce in the Mortal Realm but were not difficult to find in the Spiritual Realm. Then, he rented a quiet room and began to Practice. In the quiet room, Lin Tian took out the "Dark Nether True Fire" spiritual skill obtained from the stone tablet and began to study it carefully. He found that this spiritual skill was extremely powerful, but at the same time, it consumed a lot of spiritual energy. If he could not master its essence, it would be difficult to use it flexibly in actual combat. Through continuous cultivation and comprehension, Lin Tian gradually mastered the core skills of "Dark Nether True Fire". He found that the key to this spiritual skill was the precise control of the flame. Only by perfectly combining the temperature of the flame and the flow of spiritual energy could he exert its true power. After several days of hard training, Lin Tian was finally able to control "Dark Nether True Fire" at will and exert its maximum power. At the same time, Lin Tian did not relax the cultivation of other spiritual skills. He continuously practiced "Spiritual Light Transformation Shadow" to make his body movement more agile, almost able to evade the enemy's attacks in an instant. In addition, he further improved his ability to control spiritual energy and combat awareness through in-depth study of Xuan Tian Zhen Jie. With the gradual improvement of his cultivation, Lin Tian felt that he was more and more proficient in the use of spiritual skills. He understood that this secret art competition was not only a test of his own strength, but also a challenge to his mental state and adaptability. Only by remaining calm and making sharp judgments in actual combat could he win in the competition surrounded by powerful enemies. Finally, the day of the secret art competition arrived. Cultivators in Xuantian City gathered outside the competition venue one after another, and the entire city was shrouded in a tense and excited atmosphere. Lin Tian passed through the crowd and came to the registration place of the competition, submitting his name card. The competition venue of the Xuantian Ancient Clan was set in a vast area of concentrated spiritual energy outside the city. This area was filled with ancient restrictions and arrays, obviously set up by the Xuantian Ancient Clan specifically to test the strength of the contestants. As the registered cultivators arrived one after another, the atmosphere in the competition venue became increasingly tense. Lin Tian noticed that all the cultivators participating in the competition were highly skilled. Many of them had even reached the later stage of Foundation Establishment, and there were no shortage of experts at the Core Formation Stage. Such a lineup made Lin Tian feel a bit of pressure, but at the same time, it also aroused his fighting spirit. The bell rang to signal the start of the competition. All the contestants were divided into several groups, and each group would compete in an independent array space. Lin Tian was assigned to the third group. The cultivators in his group all looked solemn, obviously attaching great importance to this competition. With the activation of the array, Lin Tian felt that the surrounding scenes suddenly changed. He was transported to a desolate valley. The spiritual energy here was thin, and everything was dead. Only a few shrill roars could be heard faintly from the valley, as if some vicious existence was hidden. "Is this the competition venue?" Lin Tian looked around, secretly vigilant in his heart. He knew that this competition was not only a contest between cultivators but also might involve dealing with various environments and unexpected situations. He did not act rashly but calmed down, operated his divine sense, and carefully probed the situation around. Soon, he found that there seemed to be an area with more concentrated spiritual energy at the end of the valley, which was most likely the key to the competition. Lin Tian took a deep breath and carefully headed towards the depth of the valley.
