Huang Yongjue and the nine-tailed fox were stunned when they saw the stone gate rumbling open.

Especially the nine-tailed fox, it has been a long time since it found the tomb of the Nine Heavens Xuannu, and it has figured out the secret of the boiling water river by itself, but how many times has it been discouraged in front of this stone gate, not that it does not want to go in, but it has exhausted all means, but there is still no way to take this stone door.

When it saw Tang Ding click a few times in front of the stone gate, and the stone gate opened with a bang, the surprise in its heart was incomparable.

Huang Yongjue and the nine-tailed fox were surprised, and Tang Ding himself was extremely shocked.

Although Tang Ding unlocked the combination lock of the Nine Palaces Bagua, he did not expect that the combination lock of the Nine Palaces Bagua was still so sensitive after thousands of years, which shows that the manufacturing process of the stone door combination lock at that time was so high that it was proud of the past and the present.

However, it can be seen that this Nine Heavens Xuannu's mastery of Qimen Dunjia has reached an unbelievable level.

The stone door opened, and the two of them looked into the stone gate together.

Inside the stone gate, which was originally pitch black, a little fire suddenly appeared, and then the fire became larger and became a lamp. It turns out that this place, like the stone wall passage outside, is a permanent lamp.

Legend has it that the lantern is fueled by the grease extracted from mermaids. A mermaid is not a legend, but a mermaid who lives in the sea, with a tail like a fish and a body like a human. Sharks have been found all over the world, and they are real. The grease burns very slowly, and an oil lamp can burn for hundreds or thousands of years.

Huang Yongjue and the nine-tailed fox followed Tang Ding and entered the stone gate together.

Inside the stone gate is a passage, and a person and a fox follow behind Tang Ding, following in unison. Just now, Tang Ding's performance of opening the stone gate has completely conquered the nine-tailed fox, and when Huang Yongjue was defeated by Tang Ding with one move and was played by Tang Ding, Huang Yongjue had already surrendered from his heart, otherwise he would not be willing to follow Tang Ding and test whether Tang Ding had the ability to protect him.

"Be careful, don't get too close to me, five steps away from me, and remember to follow my steps, and don't make a mistake. ”

Although Tang Ding is not sure if there are any traps here, the ground here is paved with bricks, and if there are traps, such bricks are the best trigger point.

However, Tang Ding doesn't want to have a mechanism, in this kind of confined place, if there is a strong bow and crossbow, even if he has a Daomen Xuangong stepping on the fight, even if he is already a master of extreme strength, to avoid this strong bow and crossbow, it depends entirely on luck.

In most cases, a master of transformation like Tang Ding can control his life and death, but once life and death are due to luck, it means that it is extremely dangerous.

Tang Ding walked on this brick, not in a straight line, but two steps forward, one step back, and sometimes a diagonal step.

Huang Yongjue and the nine-tailed fox, who followed Tang Ding, were not worried that they would make a mistake if they couldn't remember, because this place had been empty for thousands of years, and thick dust had fallen on the bricks, so every step Tang Ding took left footprints on the dust.

Although ordinary people see that there is no law to speak of the bricks here, Tang Ding is not blindly walking, but according to the law of wearing nine shoes and one, three on the left and seven on the right, two or four for the shoulder, and six or eight for the foot.

Wearing nine shoes one, three on the left and seven on the right, two or four for the shoulder, and six or eight for the foot is the trick in the "Luo Shu", which contains great wisdom.

And it is said that this river Tuluo book is Fu Xi saw the tortoise shell in Luoshui and came to his senses, but according to Tang Ding's familiar reading of history books, according to his research, this river Tuluo book is from the Yellow Emperor.

According to the following: "Historical Records Yinyi" cloud: "The Yellow Emperor toured the river to the east and crossed Luo, repaired the altar and sank the bi, received the dragon map in the river, and the turtle book in Luo. ”

"Notes on the Book of Water?Luoshuitiao" quotes the "Diji" and says: "Luoshui enters the Zhongti Mountains in the east, and flows east to Yishiye." In the time of the Yellow Emperor in the past, the sky was foggy for three days, the emperor traveled above the Luoshui, saw the big fish, and the five animals were drunk with Jiao; the sky was very rainy, seven days and seven nights, and the fish flow began to get books. ”

Shen Yue, a Liang writer in the Southern Dynasty, said in the Book of Song: "The Yellow Emperor sits on Xuanhu and Luoshui, and there is a phoenix title in front of the emperor. ”

Luo Ping's note "Hetu Jade Edition" cloud: "Cangjie is the emperor's southern tour, climbing the mountain of Yangxu, facing the water of Xuanhu Luo, the spirit turtle bears the book, and the Danjia Qingwen is given to it." ”

On the contrary, the legendary Luo Shu of Fuxi Shenwu only has legends, but no clear historical records.

Therefore, Tang Ding still thinks that it is more appropriate that this Luo Shu is written by the Yellow Emperor.

The Nine Heavens Xuannu is the teacher of the Yellow Emperor, so whether this Luo Shu was passed on to the Yellow Emperor by the Nine Heavens Xuannu is not clear, and there is no way to verify.

But Tang Ding could see from the "password lock" of the gossip of the Nine Palaces on the stone gate just now that the Nine Heavens Xuannu was proficient in this.

Therefore, when Tang Ding crossed this road brick, he unconsciously walked according to the "Luo Shu", and this road was really thrilling and passed smoothly.

Huang Yongjue and the nine-tailed fox also felt that it seemed too easy to pass through this passage of fifty meters, after passing through the passage, Huang Yongjue breathed a sigh of relief, and did not take Tang Ding's previous warning seriously, he saw Tang Ding in front of him stop, looking ahead and not moving, Huang Yongjue moved a step to the left, wanting to be side by side with Tang Ding to see what Tang Ding was looking at.

Unexpectedly, Huang Yongjue just moved his steps and stood on a square brick that Tang Ding had never stepped on, when he felt that his body was suddenly empty, and then his body suddenly sank, and he immediately fell down.

The square bricks under Huang Yongjue's feet suddenly emptied, and they fell downward, and the falling square bricks were not one, but a large area around, except for the square bricks that Tang Ding had just stepped on, the rest of the bricks disappeared at the same time, Huang Yongjue wanted to grab the square bricks and stabilize his body, but it was difficult to do it at all, because he had no bricks to grasp at all.

Just when Huang Yongjue thought he was finished, he suddenly felt his falling figure pause and stopped in mid-air. It turned out that Tang Ding grabbed him.

Tang Ding lifted Huang Yongjue up, Huang Yongjue's eyes unconsciously looked down, under the illumination of the ever-bright lights on both sides, the bricks were still black, and they couldn't see the bottom at all, and no one knew how deep it was.

If you fall, the consequences can be imagined.

In this bottomless place, only a few lone stone pillars stand upright, and the top of the stone pillars is still topped with square bricks, and there are some slightly messy footprints on each square brick.

It turned out that Tang Ding took him and the nine-tailed fox to step on the bricks and did not fall, Huang Yongjue's heart only felt that his heart was beating straight, and after a while, it did not calm down. Huang Yongjue wiped the sweat on his forehead with the back of his hand, and his heart was almost frightened.

The danger here was beyond Huang Yongjue's expectations.

He peeked at Tang Ding, Tang Ding's expression was as usual, and he didn't hope that he would be grateful to Dade because he saved himself, on the contrary, he hated calm, and even looked ahead with a somewhat solemn face.

Following Tang Ding's gaze, Huang Yongjue saw the scene in front of him, and also knew why Tang Ding looked solemn.
