The two families of Modu Lin Xu are in-laws, so they naturally act together. Lin family, Lin Shiwu (Lin Shiyun's eldest brother, Lin Weihua's eldest son, Xu Yanshan's uncle), Lin Shixiong (Lin Shiwu's cousin), Lin Shiyun (Xu Yanshan's mother), Lin Shiyu (Lin Shiyun's sister, Xu Yanshan's aunt), Lin Zicong (Lin Shiwu's eldest son), Lin Ziqi (Lin Shixiong's only son), Xu family, Xu Hua (Xu Yanshan's father, Lin family's head, Yan Group Demon Capital Patriarch), Xu Jie (Xu Hua's second uncle Xu Mingde's eldest son, Xu Hua's cousin), Xu Ji (Xu Hua's second uncle Xu Mingde's second son, Xu Hua's cousin), Xu Qing (Xu Hua's third uncle Xu Mingfa's eldest son), Xu Yanjie (Xu Jie's only son), Xu Yanyu (Xu Ji's only daughter), Xu Yanbing (Xu Qing's only son), a total of thirteen people. Originally, there were thirteen dead soldiers in the family, but they had long since died in the dangerous ancient ruins, and there were no bones left.

The two families, mainly Lin Shiwu and Xu Hua, chose a passage and rushed in, and not long after entering, they encountered many forks in the road, and they ran for a long time and returned to the original point, making everyone's faces difficult to see.

"We've been here before, and it looks like we're stuck." Lin Shiwu looked at the marks he left on the wall of the labyrinth, and his face was very unsightly.

This labyrinth is very large, there are many forks, and the top and bottom are sealed, and there is no other way out except forward and backward.

"There are too many forks in the road, and the supplies on our bodies can last for a day and a half at most, and it is impossible to try them one by one." Xu Hua thought about the supplies carried by everyone in his heart, and they would be exhausted in a day and a half, and the paths of this fork in the road wanted to be tried one by one for more than ten days, and it was impossible to try them one by one, and his heart sank.

"......" After listening to Xu Hua's words, everyone was silent for a while, and their faces were not very good-looking.

"Husband, look at the reliefs on this wall, don't you look familiar!?" Suddenly, inadvertently glancing at the reliefs on the wall, Lin Shiyun pointed to the reliefs on the wall of the labyrinth and shouted at Xu Hua, waking up the silent people, and immediately shining the lights in their hands on the wall one by one, and the familiar reliefs appeared in front of everyone.

"Isn't this the temple we've come across before! You see, even the statues inside are exactly the same. Lin Shiyun's sister Lin Shiyu suddenly pointed to one of them and shouted, and everyone looked at it, and it was exactly the same as an ancient temple they had encountered before.

"Yes, it's the temple! Take a look at the others, there are no familiar ones! Xu Hua's eyes lit up suddenly, and he shouted at the others, and looked at it carefully.

The reliefs are one after the other, different on both sides, in a cycle. Some of these reliefs were places they had experienced in this ancient ruin, and some of them had never seen before, and of the thirty-two reliefs, they had only seen five of them, and each place was extremely dangerous, and if they were not careful, they would have died.

"I see! I get it! Dad, uncle, come and see. After watching it repeatedly for a long time, Lin Zicong suddenly shouted excitedly, which shocked everyone's hearts, and they all showed joy and gathered around Lin Zicong.

"Zicong, what did you find?" Lin Shiwu asked expectantly.

"Hmm." Lin Zicong nodded, pointed to a relief and said: "You look carefully, this relief is a little different from what we have seen before, each one is in the lower right corner, there is a very inconspicuous pattern, you can't see it if you don't look carefully, I took a look, each different relief corresponds to a different pattern, but at the fork in the road, one of the same reliefs on the walls on both sides of the road is the same pattern, and the other is different from the previous pattern." ”

Saying that, Lin Zicong picked the relief of the temple, walked to the next fork in the road, first turned right, and found that the pattern of the corresponding position of the temple relief on this road was different. I came to the left again, and sure enough, the pattern here is the same as before.

Confirming this, everyone's eyes flashed with a gleam, and they quickly checked each relief, and found something that made them ponder, that is, the corresponding position of this relief was the same on the left, and the adjacent relief was the opposite of it.

There are sixteen reliefs on each side of each passage, facing the forward direction, with the first one on the left hand side being the same on the right, and the first one on the right hand side being the same on the left, changing in turn, until the last one at the fork in the road is exactly the opposite of the first.

"Dad, you said it would be like this." After pondering for a moment, Lin Zicong said: "Let's start here, if we choose to go left, then left and then right, and if we choose right first, then right and then left." ”

"Reasonable, worth a try." After Lin Zicong finished speaking, Lin Shiwu nodded after a moment's silence, and then said to everyone: "Let's try according to Zicong's method, go to the right first." ”

After speaking, Lin Shiwu and Xu Hua took the lead in turning right, then left, then right, then left, and so on, right, left, right, left, right, left, right,

But it didn't take long for him to encounter a turn with no fork in the road, breaking the order of moving right, left and right, and turning two left in a row. Stopped and looked at the reliefs on both sides again, the order was exactly the same as the first passage, and the order of right, left, right and left was chosen, and continued to move forward, running for more than an hour, and everyone came to a straight passage twice as long as the previous passage. After another hour of walking along the passage, the group returned to the original point. But this time they were not discouraged, because they finally figured out the key to getting out, which was the extended passage connecting the two roads.

With the hope of getting out, they went full speed this time, and it took less than half an hour to return to this long passage. After careful inspection, it was found that there was a unique relief on one wall in the center of the passage, on which was a nine-square grid, and in each large grid was a small nine-square grid, a nine-nine-eighty-one grid, some of which had different characters written on it, and some of which were empty.

Lin Zicong stepped forward and touched it lightly, darkening the relief, the relief on the wall lit up with a white light, and a light curtain appeared next to it that was very similar to the modern computer operation interface, the content on it was exactly the same as the relief, but there were nine more options next to the pattern on the light curtain.

"It seems that as long as we can solve the problem of an ancient civilization, we will be able to get through this first hurdle." Lin Shiwu looked at the light curtain and breathed a sigh of relief, but his face was solemn, and he asked Lin Shiyun on the side, "Shiyun, has this text been cracked?" ”

"Cracked partly, this should be the number of ancient civilizations, corresponding to our current one to nine, the problem on this light curtain should be a Sudoku problem, but this Sudoku is more difficult than we have ever encountered, even if I don't have the help of a computer to solve it will take a few days."
