According to Xia Yongxin's recollection, one day, she met an old enemy unexpectedly. Maybe the other party has been tracking her premeditated. Xia Yongxin had just suffered the triple blow of losing her lover, relatives and children, and she shot desperately, but instead burst out with combat power beyond her cultivation. After a fierce fight, the other party only narrowly outplayed her, and she escaped injured.

But she later discovered that the other party had placed a kind of prohibition in her body, and her cultivation seemed to be slowly draining. What made her even more creepy was that a mysterious intruder appeared in her realm, a giant black coffin! Her spiritual power would be swallowed up by the black coffin.

On several occasions she had spotted the enemy haunting her neighborhood, seemingly manipulating the black coffin in her realm. She attacked the black coffin several times, but to no avail.

The last time, she fought to the death and lost both. The black coffin had a huge crack in it, but it was so black that it was impossible to see what was inside. And under the impact of the black coffin, her mind fell into a state of unconsciousness, so she strayed into the demon realm.

The demonic realm was in turmoil, isolated from the outside world, and the black coffin that had invaded her realm of consciousness lost control after being far away from her enemy. The black coffin also occasionally fell into madness, rampage through her consciousness, and under this impact, Xia Yongxin's mind would also not be sober.

Xia Yongxin later found this small valley in the Blood Wolf Valley, and captured a group of skilled craftsmen to build a small building here.

She also discovered that this small valley was the place where a dragon vein passed, and it was full of spiritual energy, so she set up a spirit gathering array here. Whenever she practiced, a large amount of spiritual energy was inhaled into her body, and before those spiritual energy could be refined into spiritual power, some of them were swallowed up by the black coffin. With a large supply of aura, the black coffin no longer consumed her spiritual power frequently.

Wu Wu asked, "When do you get sick, when is it? daytime or night?"

"Evening!" Xia Yongxin replied with certainty, because she started to get sick at night every time.

"Think about it again, before the onset of the disease, that is, before the black coffin went on a rampage in the realm, what was its different behavior?" asked Sanssoucian.

"Let me think about it...... By the way, the lid of the black coffin will open partially. Xia Yongxin recalled.

"Evening ...... Opening the lid of the coffin...... "Sanssouci fell into deep thought."

"Is there a regular cycle of onset, such as how many times a month?"

Xia Yongxin made a rough estimate before replying: "Almost all of them are concentrated in the period around the fifteenth of each month. Fifteen, full moon, I remember!"

Carefree asked eagerly, "Does it have something to do with the moon?"

Xia Yongxin nodded and said: "In the first seven days of the fifteenth day of each month, and the last seven days, for a total of fifteen days, the lid of the black coffin will be opened. And the closer to the fifteenth, that is, the fuller the moon, the lid of the coffin will open wider, and on the night of the fifteenth it will open all open. ”

Xia Yongxin continued: "Since that black coffin invaded my realm, it seems to have a kind of magic that makes me always have some hallucinations related to the moon, as if it is tempting me to like the moon. I could clearly feel the temptation, and slowly I couldn't help but like the moon. Since then, I have had the habit of cultivating under the moon at night. ”

Xia Yongxin slowly discovered that whenever the lid of the black coffin was opened, under the illumination of the moonlight, her spiritual power would accelerate to the black coffin! At first, it was still imperceptible, but the further back she went, the more obvious the signs of spiritual power flowing to that black coffin. Fortunately, a large amount of spiritual energy from the Spirit Gathering Array was replenished later, and the black coffin turned to devour those spiritual qi, but it didn't seem to be so interested in her spiritual power.

Finally, she realized that the black coffin was actually cultivating under the moonlight, first devouring her spiritual power, and later using her to devour her spiritual energy. She also discovered that the black coffin was also trying to control her divine sense, that is, trying to take it away!

Therefore, she will resist the temptation of the black coffin to let her go to the moon to play the piano. And if the black coffin didn't see the moon for many nights in a row, it might go crazy and run rampant in her realm!

Wu Wu nodded and said, "That black coffin must be used to devour spiritual energy for cultivation, and there should be a formation in it to absorb the light of the moon, and even through the moon, try to transmit some information to its owner." The master in the temple said before that there are some feng shui masters who have the ability to communicate with heaven and earth with the help of feng shui bureaus. However, in the Demon Domain, the qi is disordered and isolated from the outside world, and the black coffin will definitely not be able to communicate successfully with its owner. ”

Xia Yongxin was a little surprised by Wu Wu's opinion, and she asked suspiciously, "Is your master also a feng shui master?"

Wu Wu nodded and said, "Yes, I also learned some feng shui techniques from him. ”

Xia Yongxin's eyes flashed with a strange color.

Carefree asked again, "What is that black coffin most afraid of?"

Xia Yong was stunned: "Are you trying to find a way to restrain it?"

Carefree nodded, to help her relieve this pain, she had to find a way to restrain the black coffin.

"For example, it likes to cultivate at night, is it because it is afraid of the daytime sun?"

Xia Yongxin shook his head and said, "It hasn't opened the lid during the day, so I'm not sure if it's afraid of the sun." Even if it was afraid of the sun, when he opened the lid at night, he couldn't find sunlight to restrain it. ”

Wu Wu said: "Each kind of light, its aura and attributes are different, for example, sunlight is pure yang light, sex is fire, moonlight is feminine, sex is water, and lightning is fierce, sex is golden. ”

Xia Yongxin suddenly said: "Lightning! Yes, why didn't I think of it before! That black coffin has never opened the lid as long as there is a lightning night." Another time, as soon as it opened the lid, a small lightning bolt flashed in the sky, and it immediately closed the lid. On a bad night, it never opens the lid. ”

"The moonlight is water, the coffin is wood, and the aquatic wood. Lightning belongs to gold, and gold can overcome wood. That black coffin must be cultivating the wood technique, so it must be attacked with lightning to be effective. Worry-free said. He had heard his master talk a lot about the common knowledge of the exercises in the cultivation realm, and the attributes of the exercises would be divided according to the five elements, just like the spiritual root, for example, the wood-based exercises were not suitable for the cultivation of those with weak spiritual roots or those who lacked wood.

"What is your plan?" Xia Yong asked expectantly.
