A group of people walked into the crape myrtle palace, which was much cleaner than before, and there was a faint smell of pine in the air, presumably some cylindrical wooden doors were newly brushed with a layer of pine, and there were also some more green plants in the courtyard behind, Wang Gang didn't know what these were, but in these August seasons, they can still bloom delicate flowers, and they must not be so easy to cultivate.

Along the small stone road, to the small platform in the middle of the backyard, Xun Shuang's eyes suddenly became solemn. Reaching out and touching the stele, he kept muttering something.

"Sir, this is it, Ziwei Stargazing Terrace"

Xun Shuang didn't talk, he was still staring at the stone tablet there, Wang Gang called two colors, and Xun Shuang came back to his senses.

"Yes, this is the stargazing platform"

"There are still words on the back of this stele, sir, let's see if I can crack it"

Xun Shuang heard Wang Gang say this, and hurriedly came to the back of the stele and saw two columns of small characters of Qin seal.

Heaven is full of water, and the earth is sixty percent of it; The earth is two fires, and the heavens are seventy; Heaven is three trees, and the earth is eighty percent; The earth is four gold, and the sky is ninety; Heaven gives birth to five earth, and the earth is ten percent

Xun Shuang read it out in a low voice, and Wang Gang next to him said as if asking for merit.

"The county lord said that this is the formula of Hetu, but we don't know what it means."

"Yes, this is the mantra of Hetu"

"What does this mean, is there any treasure or anything underneath?" Wang Gang couldn't help but ask.

Dong Wan'er next to her rolled her eyes for a while, this is too beautiful. Hurriedly stretched out his little hand and pulled Wang Gang.

According to legend, when Dayu, Luoyang Xiluo water surfaced a turtle, carrying the "Luo Shu", dedicated to Dayu. Dayu succeeded in controlling the water with this, and then divided the world into Kyushu. According to this, the nine chapters of the Dafa are also formulated, the society is governed, the river is mapped, the book is published, and the sage is the same."

After Xun Shuang finished speaking, he glanced at Wang Gang and Dong Wan'er, and said slowly.

Presumably, the Qin State occupied Luoyang, and once again built a stargazing platform to observe the heavenly phenomena, and watched the Qin seal on the tombstone for the teacher, which was both rigid and soft, round and strong, and must have come from the hand of Li Si, the prime minister of the Qin State. As for this river map, it's not difficult."

After Xun Shuang finished speaking, he kept pacing along the small platform, walking over and over again and silently calculating.

Xun Shuang has a deep study of the I Ching gossip, and is naturally no stranger to Hetuluoshu, he walked around the small platform a few times, and found that there were nine stone slabs on the small platform, arranged in a nine-square grid, and he couldn't see how to crack the mechanism for a while.

Wang Gang and Dong Wan'er looked at Xun Shuang with hope on their faces, but time passed little by little, from the middle of the day to the west, and they still didn't see Xun Shuang find the mechanism to crack it.

"Mister"

Wang Gang screamed softly, Xun Shuang glanced at him, and continued to pace on the small platform.

"This is the crape myrtle stargazing platform, can it only be opened at night," Dong Wan'er said in a low voice.

Xun Shuang was stunned for a moment when he heard Dong Wan'er's words, and then laughed.

"Old Fool"

After speaking, he walked down the stone steps, chose to enter the platform from due north, stepped on his feet, pinched his fingers, and muttered in a low voice.

"Ziwei is now the meridian, Shuanglu is at the wall, the purple is broken in the ugly, and Jiaji is rich and noble......"

When Xun Shuang finished reading, he just finished walking around, came to the front of the stone tablet, took a deep breath, and shouted.

I saw that the stele slowly turned half a circle, and the stone slab in the middle sank downward, revealing a small square, Wang Gang was stunned when he saw the square, he didn't expect that there would be a dark grid like an exchange device here. Suddenly, my heart was excited, and this crape myrtle stargazing platform and exchange can also be installed with an exchange device.

And Xun Shuang saw that the stele had turned half a circle, and he was also relieved, and suddenly a sense of exhaustion came up, and he stumbled, and Wang Gang next to him hurriedly stepped forward to support him.

"Are you alright, sir?"

"It's okay to be a teacher, but I'm a little tired, go back to Zhuyuan first." After speaking, he glanced at the square and staggered outside.

For a while, Xun Shuang seemed to be a few years older, and Wang Gang hurriedly stepped forward to help.

What Wang Gang didn't know was that just now Xun Shuang used his exclusive skills to spend so much effort.

Qimen secret method, Xun Shuang's exclusive skill, can crack the mechanism, see through the camouflage, can not be used again within three months, and is weak for three days after use.

Wang Gang asked Hua Yu in the distance to go to Huguan and take an exchange device over, he can't get out of Luoyang yet, but fortunately, he had prepared before, bought a few exchange devices and put them in Huguan, as long as Hua Yu took one.

Wang Gang sent Xun Shuang back to the bamboo garden, Xun Shuang glanced at Wang Gang meaningfully, and then thought about walking in the garden.

When Wang Gang returned to Ziwei Palace again, Dong Wan'er was still waiting for him next to the stone tablet.

"Is it the thing you're looking for?" asked Dong Wan'er with some uncertainty.

"I don't know yet, I can't confirm it until Hua Yu brings it" After Wang Gang finished speaking, he stretched out his hand to take Dong Wan'er into his arms, now there are only two of them in the entire backyard, he has no scruples, and he is also a person who has tasted the joy between men and women, so he is naturally greedy for the big beauty in front of him.

"You... You"

Dong Wan'er struggled twice, and leaned into Wang Gang's arms, since he knew Wang Gang's secret, this man gave him more peace of mind.

The two of them were enjoying the quiet time, watching the sun gradually set in the west, but a woman coughed in a low voice behind them.

Dong Wan'er hurriedly broke free from Wang Gang's embrace, tidied up her clothes, and her cheeks were a little blushing.

"Can you say hello before you come, and deduct your salary like this next time?"

Wang Gang glanced at Hua Yu behind him, Hua Yu was dressed in red, with a layer of fine beads of sweat on his forehead, holding a crimson sword of Yitian, looking at him angrily.

Hua Yu has been with him for so long, so she naturally knows what salary means.

"When did you pay me, you black-hearted boss"

"Okay, okay, I was wrong, Sister Huayu, do you bring something?"

Wang Gang looked at the appearance of Hua Yu, presumably running back and forth, and went to Huguan to say less than forty miles. In less than two hours, she could walk back and forth, presumably all the way.

"Hmph" Hua Yu snorted coldly and handed the thing to Wang Gang.

Dong Wan'er next to her couldn't help but smile when she saw it, and pulled Hua Yu into the distance.

"Wan'er, don't go"

Originally, Dong Wan'er wanted to avoid here, after all, turn on this thing, in case Wang Gang didn't want her to know, it was somewhat inappropriate for her to stay here, but she didn't expect Wang Gang to take the initiative to stop her.

"I'll teach you how to use this thing now, if there is another place to open it, if it's inconvenient for me, you can let Hua Yu bring it, and you can open it" Wang Gang looked at Dong Wan'er and said seriously.

This is also what he is thinking about, he can't rely on the exchanged characters for everything, and sometimes he has to leave a way out for himself, which also gives Dong Wan'er an extra layer of protection.

"Teach me ......" Dong Wan'er still couldn't believe it.

"General." Hua Yu listened to Wang Gang's words and wanted to open her mouth to stop it, but thinking about the matter of Huguan, Dong Wan'er already knew that the matter here was not so important.

"You are the person I trust the most in this world, and the only one who knows the secret, in case something happens to me, you also have the power to protect yourself"

After Wang Gang finished speaking, he picked up the exchange device and gently put it into the open square in the middle.
