After returning to the main area, Lin Tian didn't immediately rest but sorted out his thoughts. The powerful restriction he encountered in front of the stone door earlier made him realize that the secrets hidden in the cave dwelling were far more profound than he imagined. The hidden cave dwelling mentioned by Situ Qian was clearly no ordinary place. Lin Tian sat cross-legged, closed his eyes to adjust his breath, and adjusted his state to the best. He knew that to uncover the mystery behind the stone door, he must meet the upcoming challenges in the best condition. The spiritual energy in the cave dwelling was rich, and his spiritual power recovered quickly, and his divine sense also became clearer. "This cave dwelling seems to be not just a place for cultivation but more like a huge maze." Lin Tian thought secretly in his heart. He recalled the content in the jade slip again. Although the jade slip mentioned the origin and some information of the cave dwelling, it didn't describe the specific layout in detail. When he stood up again, his gaze was firm, and he decided to continue exploring other areas of the cave dwelling to see if he could find clues to break the restriction of the stone door. Lin Tian followed the main path and inspected each fork one by one. After some time of exploration, he came to a secret room hidden in the shadows. The entrance of the secret room was extremely concealed. If he didn't look carefully, it would be almost impossible to discover. "There might be important clues here." Lin Tian thought to himself and then pushed open the stone door of the secret room. The secret room wasn't spacious. Several spirit stones emitting weak light were embedded on the surrounding walls, barely illuminating the entire space. In the center of the secret room was a stone platform on which several ancient items were placed. The most prominent one was a jade slip emitting a faint glow. Lin Tian stepped forward and his gaze swept over the other items on the stone platform. These items seemed to be from ancient times. Some had been washed by years and appeared somewhat damaged, but one could still feel their once powerful force. The jade slip was well-preserved and emitted a faint fluctuation of spiritual energy. He carefully picked up the jade slip, felt the fluctuation of spiritual energy on it, and confirmed that there was no danger before extending his divine sense into it. Suddenly, a huge stream of information rushed into his mind. "This is detailed information about the layout of the cave dwelling!" Lin Tian was overjoyed. He found that this jade slip recorded the detailed layout of the cave dwelling, as well as the functions and uses of each area. More importantly, it also mentioned the methods of breaking various restrictions in the cave dwelling. "This information is too important." Lin Tian sighed secretly and then began to study the content in the jade slip carefully. He knew that this knowledge could not only help him break the stone door restriction he encountered earlier but also allow him to understand the entire cave dwelling more deeply and thus make better use of the resources and power within. After carefully sorting out the content in the jade slip, Lin Tian returned to the ancient stone door again. His expression was more focused, and he held a talisman found from the secret room in his hand. This talisman was one of the key items mentioned in the jade slip for breaking the restriction. The runes on the stone door still flickered with a weak light, emitting an invisible oppressive feeling. Lin Tian took a deep breath and gently pasted the talisman on a rune node in the center of the stone door. As the talisman was pasted, the rune immediately shone with a dazzling light. "It really works!" Lin Tian was delighted and then urged his spiritual power to inject into the talisman. With the injection of spiritual power, the talisman began to release a soft light, resonating with the runes on the stone door. The runes on the stone door gradually began to loosen, and the power of the restriction also weakened. Lin Tian continued to maintain a stable output of spiritual power, and his divine sense closely locked onto the changes on the stone door, fearing that the slightest mistake would lead to the counterattack of the restriction. However, this cracking process was surprisingly smooth. It seemed that with the guidance in the jade slip, the restriction on the stone door was no longer so difficult to deal with. As the last rune's light dissipated, the stone door finally slowly opened. Lin Tian let out a sigh of relief but still remained highly vigilant in his heart. He knew that there might be greater challenges hidden behind the stone door and must always be ready to deal with sudden situations. The stone door slowly moved aside, revealing a deep and secluded space behind. It was a secret passage leading to the unknown. The passage was filled with a thick spiritual energy, as if leading to some extremely important place. "This secret passage must be extraordinary." Lin Tian was secretly vigilant and then stepped into the passage. The secret passage was tortuous and winding. The surrounding walls were covered with ancient runes. These runes seemed to be constantly absorbing the surrounding spiritual energy, forming a special barrier that isolated all exploration from the outside. Lin Tian walked carefully, and his divine sense constantly detected the movements around. As he delved deeper, the spiritual energy in the secret passage became more intense and at the same time carried a hint of oppression, as if reminding Lin Tian that he would encounter greater challenges ahead. At the end of the secret passage, there was a huge stone chamber. The stone chamber was spacious and deep. In the center stood a tall stone platform, and on the platform was an item emitting a soft light. Lin Tian fixed his eyes and saw that it was a crystal-clear jade tablet engraved with ancient and complex runes, seemingly containing extremely powerful power. "This jade tablet must be extraordinary." Lin Tian's heart stirred and he slowly walked towards the stone platform. However, just as he was about to approach the stone platform, a strong fluctuation of spiritual power surged from all around, instantly surrounding him. "Not good, there's an ambush!" Lin Tian was startled and immediately retreated while sacrificing his magical artifact, ready to deal with any possible danger. However, the changes in the stone chamber were beyond his expectation. The surrounding walls suddenly cracked, and several dazzling light pillars shot out from them, directly towards the jade tablet on the stone platform. The light pillars interwove into a light curtain, firmly wrapping the jade tablet and at the same time forming an extremely powerful protective barrier. Lin Tian stood in front of the light curtain, feeling the powerful force contained within and couldn't help but be secretly startled. "The power of this light curtain is so strong. I'm afraid with my cultivation level, it's difficult to break it forcibly." He didn't act rashly but carefully observed every detail of the light curtain, attempting to find the flaw. The runes in the light curtain flowed ceaselessly, as if constantly absorbing the spiritual energy around to enhance its defense. Lin Tian knew that forcibly breaking through was not the best strategy. He had to find a more ingenious way to crack the protection of the light curtain. Just as he was deep in thought, a passage suddenly flashed in his mind that was mentioned in the jade slip: "The light curtain is the protective mechanism of the ancient array. Only by entering the array with divine sense can one find the way to crack it." "Enter the array with divine sense?" Lin Tian looked at the light curtain thoughtfully and then decided to give it a try. He slowly closed his eyes, mobilized the spiritual power within his body, and concentrated his divine sense at a certain point of the light curtain, attempting to penetrate into it through the divine sense. At first, the divine sense was blocked by the power of the light curtain, but Lin Tian didn't give up because of this but continued to deepen the penetration of the divine sense. He felt that the power of the light curtain gradually loosened, as if responding to his attempt. "It works!" Lin Tian was delighted and then fully urged the divine sense, gradually penetrating into the interior of the light curtain. As the divine sense delved deeper, Lin Tian felt an ancient and powerful will, as if guarding the secret of the jade tablet. This will carried a hint of majesty and inviolable power, making him feel a palpitation. "It seems that this light curtain is not just a simple protective array but also contains some ancient will." Lin Tian thought secretly in his heart but didn't retreat because of this. Instead, he continued to steadily advance the divine sense, attempting to communicate with that will. After some difficult attempts, Lin Tian's divine sense finally broke through the protection of the light curtain and entered the core area of the array. He felt a gentle force, which was the fluctuation of spiritual energy from the jade tablet, as if responding to his efforts. "Finally succeeded!" Lin Tian was overjoyed and then concentrated his divine sense on the jade tablet, attempting to break the protection of the light curtain through this force. However, just as he was about to touch the jade tablet, the light curtain around suddenly fluctuated violently, as if sensing an external threat. A strong counterforce surged from the light curtain, instantly repelling Lin Tian's divine sense and causing him a sharp pain. "The defense of this light curtain is so powerful!" Lin Tian endured the pain of the injured divine sense, quickly withdrew the divine sense, and stabilized his mind. He knew that his current cultivation level was not enough to completely crack this light curtain. He had to find another way. Lin Tian stood in front of the stone platform, pondered for a long time, and finally decided to retreat temporarily. He understood that at the moment, he was not capable of contending with this ancient power. He must wait until his cultivation level advanced further or found other auxiliary means to truly unlock the secret of this light curtain. He took a deep look at the jade tablet on the stone platform and then turned and left the stone chamber. Although he failed to successfully crack the light curtain this time, he had gained valuable experience and also strengthened his determination to continue improving his strength. "The way of cultivation lies in being steady and solid." Lin Tian secretly warned himself in his heart and then decided to return to the cultivation area of the cave dwelling to continue improving his cultivation. After returning to the cultivation room of the cave dwelling, Lin Tian sat cross-legged again and began to adjust his breath and recover. He knew that although the injury to the divine sense was not serious, it still needed time to recover. At the same time, he also deeply realized that there was still much room for improvement in his cultivation. Only by constantly tempering himself could he remain invincible in the world of cultivation. In the following days, while recovering the divine sense, Lin Tian continued to study the jade slip obtained from the secret room. He knew that mastering more knowledge and skills would be the key to his victory in the next exploration. As time passed, Lin Tian's divine sense gradually recovered, and his cultivation also improved further.
