Wei Wuxian ignored the little monkey and strolled towards one of the stone houses.

This stone house is supposed to be the main house, which is larger than the other four, and there are many remnants of furnishings inside. He unfolded his consciousness in the hope of finding something valuable from within. However, the owner who originally lived here cleaned up when he left, only some broken daily necessities. He didn't give up, and continued to search for a few other stone houses, but after a while, he still found nothing.

Wei Wuxian walked out of the courtyard only to find that there was a cliff outside, and according to the sunlight, he could judge that it was located on the other side of Lingtian, which made him a little confused, the Heavenly Rift Valley was a hundred zhang deep, and it was impossible to come to the higher mountainside, unless he deviated from the direction from the beginning and kept going upward.

Now it seems that only this explanation is reasonable, and it is not impossible to calculate that after walking seven miles forward from the Heavenly Rift Valley Passage, and adding the secret passage that crosses dozens of zhang, if it has been slowly upward, it is not impossible.

Wei Wuxian was relieved to figure this out, and when he saw that the pear trees in the yard were also still fresh, he picked one to satisfy his hunger. One bite down, sweet and crisp, the pear was unexpectedly delicious, so I ate two more. This pear tree must have been some years old, and its branches were luxuriant, ten feet high, covering most of the yard underneath.

Wei Wuxian was full, so he planned to drive the flying sword away, but as soon as he took out the sword weapon, he froze in place, as if he had forgotten something, but he couldn't remember anything.

He came to the courtyard again, thinking about it as he went, and recalled his trip, starting from the mouth of the Heavenly Rift, and replaying it in his mind little by little. Suddenly, my eyes lit up and I knew what the problem was.

He always felt a little awkward after coming out of the secret passage, he thought he had forgotten something, but now he remembered that the dried corpse had behaved a little erratically before he died. There is no problem for Hong Tian to leave a message on the stone slab to vent his anger, the problem is that he made the location of the 'Black Water True Scripture' too clear.

Also, where did the soil he excavated go to the tunnel, such a long tunnel could not be dug out overnight, and the amount of soil dug out was by no means a small amount, this well could not hold so much soil, someone must have helped him cover and dispose of the soil.

Wei Wuxian thought that he swept his gaze to the bones in the weeds, if he was not wrong, these people should be the palace maids of the Black Water Palace who were taking care of Hong Tianfang at that time, the Black Water Palace Lord killed people after obtaining the true scriptures, and some of them may have secretly helped Hong Tianfang cover up and dispose of the dirt that was dug up.

Wei Wuxian carefully examined the seven corpses, and the results really made him find something unusual: one of the skeletons had only four fingers on its left hand, and no thumb. Wei Wuxian immediately recalled the appearance of the dead corpse, his left hand stretched out, his thumb clasped inward, and his four fingers inserted into the cave wall. This shouldn't be a coincidence, if he wasn't mistaken, it was the code that Hong Tianfang had agreed with the four-fingered palace maid. The meaning of this is unknown.

Thinking of this, Wei Wuxian returned to the well again, and climbed back to the position where Hong Tian had been killed at that time, along the secret passage.

He first dug for a while at the place where Hong Tianfang inserted his four fingers, but found nothing.

How could it not be? Wei Wuxian was a little frustrated, could it be that he had misjudged! No, Hong Tianfang should not have made such an obvious hint, the palace master of the Black Water Palace was at least a cultivator above the Jin Dan, and the information left from the stone slab showed that this was an extremely delicate person, and he would not miss such an obvious abnormal move, and the reason why she ignored it was because her divine sense had already detected that there was nothing hidden in the cave wall, and she had obtained the true scripture as she wished.

What information did Hong Tianfang want to tell the palace maid with the four fingers? Wei Wuxian fell into deep thought. He recalled the appearance of Hong Tianfang when he died, the posture of the dried corpse was very strange, one thumb was buckled up into the cave wall, and the other hand was holding a piece of broken porcelain downwards. Maybe there's something hidden that you don't know. So where did his digging tools go?

Wei Wuxian had a flash of inspiration, lifted the stone slab below, and immersed his divine sense in the soil below, and with his current cultivation, he was able to probe his divine sense to a depth of one foot, but he didn't find anything. Wei Wuxian thought for a while, and changed his way, using the 'Earth Spirit Technique' to hook the earth qi below, and in an instant, the earth qi three zhang deep underground rose upward, so that he could judge whether there was something hidden below by the slight difference in the earth qi rising.

After a while, the corners of Wei Wuxian's mouth hooked up a smile, and there was really something abnormal below, and when the earth qi rose, it was obviously blocked by something, overflowing from both sides.

The passage was too narrow to dig, so he simply slipped out of it, went into the passage again, took out his spear, and dug it from the side according to the direction he sensed.

As the layers of dirt were peeled away, a short hoe first appeared in front of his eyes, which should be the tool used by Hong Tianfang to dig the secret passage, and then a palm-sized dark green jade plaque appeared less than a foot below it. Wei Wuxian took it out, and the tentacles were cold and piercing, and he didn't know what material it was made of.

The surface of the jade plaque is dark green, and runes are inscribed on both sides, one of which is engraved with the word 'black water', and the middle of the other side is engraved with the word 'order', it is not difficult to see that this is a token called 'black water order'.

He looked at it carefully, but found no other written record on it, so he put it on his forehead, trying to use his divine sense to find out what was inside.

But the accident happened, as soon as his divine sense touched the jade plate, the jade card turned into a cloud of black water and dipped directly into his forehead.

Wei Wuxian was horrified in his heart, and wanted to use Yuan Force to force him out of his body at the first time, but the black water was not controlled at all, and went directly towards his dantian. It seemed to be attracted by the drop of 'Tianyi Heavy Water' in the dantian, and it was firmly wrapped in it. Tianyi Heavy Water was where Wei Wuxian's Dao foundation was located, and he immediately felt as if he was being pressed down by a thousand zhang glaciers, and his soul seemed to be frozen. Almost at the same time, a large passage of scripture inexplicably appeared in my mind, and its beginning was the four ancient words of the 'Black Water True Scripture'.

Wei Wuxian was surprised and delighted, but now he didn't have the energy to take a closer look, and at this time, the black water made him feel like life was worse than death, and his whole body stiffened and froze in place, which lasted for a full hour before he got better.

Wei Wuxian breathed a sigh of relief, and once again looked inside, and found that the drop of Tianyi Heavy Water was larger than before, and there were faint runes circulating on it, which seemed to have changed a little.

He checked the rest of his body again, and everything was as usual, nothing had changed, and then he let out a long breath and focused his attention on the 'Black Water Sutra'.
