Chapter 71 Tianyin Mountains
When Mr. Yun heard this, his hands trembled and he almost dropped it on the ground.

"Grandpa, be careful..." Xin Ruyin shouted.

Old Master Yun hurriedly held the bracelet in his hand firmly and put it into the storage bag.

Only then did the three of them feel a chill on their backs.

Just imagine, if these nine heavenly thunder seeds exploded in this formation at the same time, it is estimated that nothing would be left in the formation.

Only then did Yun Hao complain: "Please go slower!"

Old Master Yun smiled bitterly and said nothing.

Xin Ruyin came to the rescue and said, "It's good that nothing happened! We should go to the appointment! It's time..."

Yun Hao nodded and walked towards his parents' house and said, "Let's go to Qingquan Teahouse to keep our appointment!"

Mother Yan Ying replied: "Be careful..."

"Be more careful when you are out there..." my father also said.

Aunt Yan Yan also said to the three of them: "Father, Xiaohao, Ruyin! Take care of yourselves outside!"

Xin Ruyin nodded and replied, "Don't worry about us! You three elders should take good care of yourselves at home!"

After saying that, the three of them walked out of Yunwu Mountain, one in front and two behind, and flew towards the Qingquan Teahouse in Jinma City on their swords.

The three of them came to Qingquan Teahouse and saw the middle-aged shopkeeper again.

The middle-aged shopkeeper also saw the three people, so he hurriedly came to the three people and bowed: "Greetings, three seniors!"

Yun Hao asked the middle-aged shopkeeper, "Shopkeeper! Has the Taoist friend who met us last time come?"

The middle-aged shopkeeper shook his head upon hearing this: "I have never met any senior before!"

Old Master Yun frowned and said, "Oh! Not here yet!"

"It's okay! It will be here soon!" Xin Ruyin said.

Yun Hao nodded when he heard this, and instructed the middle-aged shopkeeper: "Open the same private room as last time for us. When Fellow Daoist Yin comes, just let them come directly..."

"Okay, senior..." the middle-aged shopkeeper agreed.

Yun Hao and the other two walked into the same private room they had been in last time, sat on the long bench and waited.

The middle-aged shopkeeper observed the man's expression and brought over a pot of spiritual tea, then retreated and closed the door.

The three of them drank tea while waiting for the arrival of the three old men surnamed Yin.

It didn't take long, just over half an hour, for the three Yins to arrive at Qingquan Teahouse. After asking the middle-aged shopkeeper, they learned that Yun Hao and the other two had arrived.

So the three of them walked towards the private room where Yun Hao and the others were without hesitation.

"Dong dong dong" the knock on the door sounded.

When Yun Hao and the other two heard this, they knew that the old man surnamed Yin and his companions had arrived.

Yun Hao opened his mouth and said loudly to the person outside the door: "Fellow Daoist Yin! Please come in!"

After hearing this, the old man named Yin outside the door opened the door and the three of them walked into the room.

In addition to the old man surnamed Yin, there was one person wearing a gray robe, over forty years old, with a square face, a wide nose, and a pair of thick black eyebrows; the other person was a young man in his twenties wearing purple clothes, who looked quite handsome.

As soon as the old man surnamed Yin walked in, he pointed at Yun Chong and introduced him to his son and grandson: "These three are the members of the Yun family, and this is Yun Chong, fellow Daoist Yun..."

The old man surnamed Yin introduced Yun Hao again: "This is Daoist Fellow Yun Hao. Although he is young, he is already the patriarch of the Yun family!"

The old man surnamed Yin pointed at Xin Ruyin and introduced her to his son and grandson: "This is the formation master for this trip, Fellow Daoist Xin Ruyin! Of course, she is also the Taoist partner of Fellow Daoist Yun Hao..."

After the old man surnamed Yin introduced Yun Hao and the other two, he also introduced his own son and grandson to them.

The old man surnamed Yin pointed at his grandson and said with satisfaction: "Three Taoist friends, this is my grandson Yin Jiao. He is now 21 years old and has already advanced to the initial stage of foundation building!"

After introducing his grandson, the old man pointed to the middle-aged man in gray robe and introduced him: "This is my son Yin Lie. He is fifty-three years old now and has reached the middle stage of foundation building. As for me, my name is Yin Xiong!" "Hello, two fellow Daoist Yins! Three fellow Daoist Yins, please sit down..." Yun Hao and the other two clasped their fists and spoke politely.

Yun Hao stood up and made way for a bench to sit next to Xin Ruyin.

The old man surnamed Yin looked at Yun Hao and the other two and said, "I think Fellow Daoist Xin has already refined the formation flags and formation plates!"

"Of course it has been refined! I just wonder where the cave that Brother Yin mentioned is?" Xin Ruyin first replied, then asked.

"Okay, okay! Now that it has been refined and we are ready to go somewhere, it is time to be frank with the three fellow Taoists..." The old man surnamed Yin said to Yun Hao and the other two.

After hearing this, Yun Hao and the other two perked up and listened quietly.

"That place is on the edge of the Tianyin Mountains in Yinzhou, Yuanwu Kingdom! It is about 4,000 miles away from our Tianyin Sect!" The old man surnamed Yin began to speak.

"Tianyin Mountains! It's so close to your Tianyin Sect? When we break the formation, we won't be discovered by you, the Tianyin Sect, right?" Yun Hao said with a frown.

Upon hearing this, the old man surnamed Yin said confidently: "Don't worry, fellow Daoist! This place is located in a large canyon, surrounded by seven large mountains. It is a very secret place! The surrounding area is shrouded in fog all year round, and ordinary people will not find this place! If it weren't for my grandson getting that travel book, we would still know nothing about it until now!"

Yun Hao and the other two felt relieved after hearing this.

"Then when will we set off for the cave?" Old Man Yun Chong said at this time.

The middle-aged man in gray robe, Yin Lie, said without blinking, "Of course the sooner the better! Every minute of delay increases the possibility of being discovered by others..."

Everyone nodded in agreement when they heard this.

The old man surnamed Yin stood up and made a decision, saying, "Let's set off now! Otherwise, there will be chaos..."

The main reason is that he has the highest cultivation among the six people, and he is also the head of the Yin family.

Although Yun Hao and the other two were quite dissatisfied with the direct decision made by the old man surnamed Yin, they did not say much. It is better not to be the first to take action if you can hide your shortcomings.

Several people stood up, and Xin Ruyin also put away the soundproofing ban.

Then he followed the old man surnamed Yin and walked out of the private room.

Yun Hao walked outside and saw the middle-aged shopkeeper. He took out another bottle of Huanglongdan and gave it to the shopkeeper and placed it on the counter.

Without waiting for the middle-aged shopkeeper to express his gratitude, the six people left the Qingquan Teahouse under his respectful gaze.

After leaving Jinma City, the six people flew all the way towards Yinzhou of Yuanwu Kingdom.

Yinzhou, the fourth largest state among the twelve states of Yuanwu Kingdom, got its name because there is a Tianyin Mountain Range in Yinzhou. This mountain range was occupied by the Tianyin Sect, one of the six sects of Yuanwu Kingdom, thousands of years ago.

After flying for five days, the six people finally arrived at the Tianyin Mountains. Then the old man surnamed Yin led the way and stopped only when they reached a place with seven dangerous peaks.

Seven dangerous peaks surround a large canyon in the direction of the Big Dipper.

For unknown reasons, the canyon is surrounded by dark fog all year round.

The old man surnamed Yin led five people and walked towards the canyon.

As soon as Yun Hao and his group came into contact with the dark fog in the canyon, they felt dizzy.

At this time, the old man surnamed Yin said to Yun Hao and the other four, "Everyone, pay attention! This dark fog has the effect of disturbing people's consciousness..."

Upon hearing this, everyone perked up and dared not be careless in the slightest.

After about ten minutes, the six people came to a place covered by a black cover. Nine huge copper pillars stood on the edge of the black cover.

The old man surnamed Yin led the five people and walked along the black cover towards a place where there was a hint of silver light.

When everyone arrived at the place, they saw that there was a fist-sized crack at the junction of the copper pillar and the black cover where the silver light was emitted.

Seeing this, Xin Ruyin used her many years of knowledge of formations to explain to the five people, "This should be one of the nine centers of the Nine Nether Mysterious Dark Formation. Maybe something went wrong and it was damaged."
