Without the water pattern shield, Lin Chen was a little uneasy. The shield card defended against common dangers. Physical attacks and magic attacks hot and cold viruses, but some special intrusions, such as spiritual consciousness, could not be blocked. From this point of view, Xiao Black Turtle's water pattern shield is much more useful than the shield card. Who knew there was any danger inside? Lin Chen looked around and saw the little black turtle crawling in, its head already stuck into the fog. Nothing happened. Lin Chen breathed a sigh of relief, the little black turtle had no tendency to die. The next moment, Lin Chen was stunned and looked at the little black turtle with wide eyes. He saw the little black turtle trying hard to open its big and small mouths, like a snake's long neck, swelling bigger and bigger, and suddenly contracted violently. Lin Chen only saw all the mist inside moving, gathering towards the little black turtle like a whirlpool. The little black turtle was like a vacuum funnel, sucking the mist into the body continuously. Does the little black turtle still have this skill? Lin Chen was stunned and couldn't help but think of the "holy beast" Meng Xueqing told him. Could it be that the little black turtle was really a very advanced beast? Or is it simply the child of that giant turtle in space? But Lin Chen clearly saw turtle eggs as big as space capsules. No matter what secret this little black turtle has, Lin Chen thinks that as long as he raises it, he should be able to know it. But what troubles Lin Chen is that compared with the little black turtle when he was born, except that the back shell is a little harder, it is almost Nothing changes. Recently, I have been feeding it spiritual grass. The large amount of spiritual grass I exchanged and the spiritual grass collected in the wild, except for making cards, basically gave it to eat. Even a pig can be slaughtered, but The little black turtle didn't grow any flesh at all. I don’t know how long it will take to raise this child. Just when Lin Chen was thinking wildly, suddenly a pattern flashed out on the back of the little black turtle, glowing green in the haze. The black dots were divided into nine piles, neatly arranged on the back of the little black turtle. Hide and appear. "Luo Shu?" Lin Chen said two words in surprise. The pattern on the little black turtle's back was exactly the same as the ancient Luo Shu on Earth. Five was in the center, two and four were shoulders, six and eight were feet, and nine shoes were worn. Three on the left, seven on the right. Lin Chen remembered that in ancient legends, Luoshu was carried out of Luoshui by a turtle. Is this little black turtle related to Luoshu? Why does Lua Shu appear after absorbing these mists? After half a stick of incense, all the mist of the underground palace was sucked in by the little black turtle. Lin Chen's consciousness showed no sign of being suppressed anymore. The little black turtle crawled back into Lin Chen's arms, absorbing so much mist that the little black turtle's size was no longer If there is any change, the pattern on the back will disappear. Just when Lin Chen was a little confused, a special message came from the contract with the little black turtle, and patterns were generated in Lin Chen's mind. It was very vague, but it felt extremely mysterious. The forty-five black dots that make up Luo Shu were constantly changing in the dark void. Lin Chen tried hard to understand, but his head hurt more and more, especially the back of his head, which felt like needles. The forbidden area is this underground palace. Lin Chen suddenly felt a sense of enlightenment. A pattern clearly appeared in his mind. Many cards with different functions were arranged to form a powerful formation. The hiding part, the trapping and killing part, and the fog-inducing part were all arranged. Part, the formation self-study part, all were clearly passed into Lin Chen's mind. Lin Chen has never learned formations, but at this moment Lin Chen felt that even without Meng Xueqing telling him, he could find this hidden formation and enter this underground palace. But now Lin Chen just saw that there was a formation here, and the functions of each formation base, which could not be broken at all. Lin Chen felt that as long as he persisted, persisted for a while, and watched the transformation of those black spots, he would definitely be able to defeat it. Break this formation while it is intact. But the pain on the back of his head became more and more painful. Lin Chen shouted and spit out a mouthful of blood, and all the impressions in his mind disappeared completely. Lin Chen hurriedly took out a healing card, crossed his legs and performed exercises, and it took a while to repair his body. Thinking of the scene just now, he felt it was extremely mysterious, and Lin Chen was surprised to find that the formation he had described in the previous cultivation scrolls, I have a very shallow understanding. The formation of this underground palace can also be easily seen with spiritual consciousness. In other words, he has already mastered the formation technique, which surprised Lin Chen. Like the alchemist and the weapon refiner, the formation master is also an extremely precious existence in the world of cultivation. Although it is not as high as the card maker, it cannot be ignored. . And an excellent card maker must be an array mage. The most powerful power of cards is to form a card array with many cards to strangle the opponent, or to arrange a flexible card array. If you don't know the array, even if you can control it, you can't control it. Even if there are too many cards, qualitative changes will not lead to quantitative changes, and the reputation of the senior card maker will be wasted. Now that I am getting started with formations, I have one more pass to the realm of real advanced card makers. If I get the "Jitian Card Codex" and get rid of the constraints of cultivation like Zhan Hailan, even if I am incompetent, my strength will still be Can rival other cultivators?. It is said that "Luo Shu" is the ancestor of formations. Could it be that the Luo Shu pattern on the back of the little black turtle flashed just now when I started to use the formations? If so, could I let the little black turtle replenish energy like mist, and then I could do it? Gain more knowledge about formations from the little black turtle? Lin Chen decided to try it out in the fog after going out, but now he should see if he could get out of this forbidden area. The formations here have been almost destroyed by Meng Xueqing. Otherwise, even if Lin Chen is a beginner in formations, he would not be able to break such a high-level formation. However, once he is familiar with the formations here and does not need to resist the fog, Lin Chen's speed Much faster. Lin Chen quickly arrived at the end of the underground palace, and a stone gate appeared in front of him. Looking at the lines on it, Lin Chen knew that it was another void gate. Lin Chen was already used to it, and carefully felt the energy fluctuations above, frowning slightly. Logically speaking, since Meng Xueqing came in from the outside, the formation here should be broken, but why did Lin Chen sense that five Hou-level cards still need to be sacrificed at the same time to get out? Lin Chen did not have five Hou-level cards, nor could he use five Hou-level cards at the same time, but to Lin Chen's joy, the energy of this card gate was rapidly weakening. Lin Chen quickly thought of a possibility. Perhaps it was because he and Meng Xueqing destroyed the mirror array, directly destroyed the seventh gate, and also took away the Amaterasu card. The destruction of the mirror array and the Yin-Yang Two Symbols Array were synchronized. , the seventh door of the mirror formation was broken open, and the formation here was also weakening. Although there are currently five Hou-level cards, Lin Chen feels that if he uses five Bo-level pinnacle cards, he might be able to open them. The energy here is lost too fast. Maybe after a while, it will become the equivalent of five cards. The energy of the Bo level card. What Lin Chen couldn't figure out was why it was so easy for Meng Xueqing to get in without his own help. The two of them almost couldn't get into the mirror formation together. Lin Chen never believed that Zhan Hailan's level of formation formation was low, and how could he have such a big flaw if he could create the Yin-Yang two-image formation by himself. The only possibility is that Zhan Hailan wants outsiders to come in, or to be precise, he wants outside experts to come in. "And after Meng Xueqing came in, the stone door jamming here was intact, but she still couldn't get out. Could it be that Zhan Hailan didn't want the people inside to get out? Wanting the masters from outside to come in, but not wanting the people inside to go out, he arranged a Yin-Yang two-symbol array Lin Chen now increasingly doubts that Zhan Hailan used a Yin-Yang two-symbol array to hide Jitian Kadian and his own tomb. It should be Don't worry, maybe Zhan Hailan didn't die of old age at all.
