"Thirty-six. More than 700 years ago, it was necessary to pick up twenty-four pieces in twelve times; More than 300 years ago, 12 pieces needed to be picked up in six times. When the time comes, you can just follow the prompts. But please be careful, every time the gravel appears in front of you, two pieces will appear at the same time, you must pick up one piece per person and then put it together, you must not pick up two pieces by one person, otherwise all the work will be wasted! He Taichu said with a serious expression.

"Oh? Can only pick up one piece per person? Yan Moying thought it was very interesting.

"Yes, remember! This one...... I might as well tell you directly, the gravel you need to pick up is the broken Heavenly Spirit Destiny Stone, which is originally a heavenly thing, and it is related to the fate between two individuals, including family, friendship, romance and other kinds of emotional fate. Therefore, the two pieces of gravel that appear at the same time each time must be contaminated with the unique breath of the two individuals who are destined to be put together. The reason for this heavenly fate is that a love affair interferes with the fate of other feelings, so it needs to be repaired by lovers. The stones you put together each time are still not independent and complete, and after you travel back to this world, you will need the next round of combinations. In order to prevent mistakes, He Taichu said bluntly to Yan Moying.

"So that's the case, the younger generation understands. The younger generation itself must not make mistakes, and the younger generation's lover is also a serious and reliable person, the younger generation will tell her everything that should be told her, and I believe she will be very cautious. Yan Moying said this, so that He Taichu could rest assured.

"Hmm. It should also be noted that you will need to go through four crossings to go back and forth. First travel to the first life more than 700 years ago, and after walking through a lifetime, travel back to this life. At this time, you will see fireworks that have not been set off, and after dark, you must remember to light them and let them fly into the sky, and after dawn, the door to the second life more than 300 years ago will be opened for you. Fireworks must be lit on the same day and cannot be delayed. When the door to the Second Life is opened, you need to enter as soon as possible, and not for long. He Taichu once again explained to Yan Moying in detail.

"The younger generation will not forget. Just now, the predecessors said that after we travel back to this world, those gravel that have been put together in pairs still need to be combined again, what is this for? Yan Moying continued to ask carefully.

"Good question, even if you don't ask, I will make this matter clear to you. When you finally travel back to this world, you will see the eighteen stones that were previously made up of thirty-six broken stones in twos and twos, and after combining these eighteen stones again, they will be restored to a complete flat boulder, and from one side of this boulder, you will see a map, which will show you the location of the Gangfeng Town Evil Sword and the Gangfeng Town Evil Sword Technique that need to be used to save you, and on the other side of the boulder, there will be the cultivation method of Xuanqi Crystal, and you need to copy the map and cultivation method immediately. Two copies of the map need to be made, one for each person. He Taichu replied.

"It turns out that gravel has such a purpose!" Yan Moying sighed.

"The day you travel back from the second life will be the day of the ancient moon, and from the day of the new moon, you must start the retreat and cultivation of the Xuan Qi Crystal next to the big stone in the same place until the day of the wax moon. From the moment you start cultivating the Xuanqi Crystal in retreat, the maps and cultivation methods on the front and back of the big stone will disappear, which is what makes you copy it in advance. He Taichu said.
