Immortal cultivation starts with copying.

In Linghu Valley, in the secret room of the Linghu clan, there were only Chen Yunhao and Linghu Yuan.

"Fellow Daoist Chen, I just need you to swear an oath in your heart. The Soul-Appraising Technique can only be used by you and must not be passed on to outsiders..."

The art of judging spirits is of great importance. Not to mention that almost no one in the human and demon worlds knows about it, even in the spirit fox clan it is only known by a few elders. However, only Linghu Yuan can cast the spell, which shows how mysterious it is.

However, considering the miraculous effectiveness of the Spirit Appraisal Technique, it is not excessive to keep it secret.

Linghu Yuan's request was not excessive, so Chen Yunhao nodded and agreed without thinking.

Chen Yunhao stretched out his hand and drew in the air, and a mysterious rune appeared in the air.

"I promise that the Spirit Fox Family's spirit-appraising technique will not be passed on to outsiders...!"

As soon as Chen Yunhao finished speaking, the rune flashed in the air and disappeared into Chen Yunhao's forehead.

This is the oath in the heart. The oath made by the cultivator is not made casually. Once violated, the consequences may be death, or at least the cultivator will lose the chance to cultivate immortality in this life.

Seeing that Chen Yunhao had made his vow, Linghu Yuan nodded in satisfaction, then reached out and touched Chen Yunhao's brow.

The art of spirit appraisal has been passed down orally for thousands of years, and there is no written record or jade slip record at all.

Therefore, apart from word of mouth, it is impossible to obtain it from other channels. If Linghu Yuan is unwilling to teach, even soul searching will be useless.

A piece of information was directly imprinted in Chen Yunhao's mind. It was neither a textual existence, nor a rune, nor an image.

Instead, it was like a memory, directly imprinted deep in his mind, like a long-forgotten memory that was revealed today.

So Chen Yunhao immediately understood how to perform the Soul Appraisal Technique, and of course also knew the necessary conditions for its use. He couldn't help but secretly curse Linghu Yuan in his heart for being such an old fox.

The spirit-judging technique had such a huge drawback, yet he was not told about it in advance. However, when he thought about it carefully, how could such a heaven-defying magical power be performed so easily?

Although it comes at the cost of lifespan, it is acceptable in certain emergencies.

Of course, the benefits must be collected in advance. No one can tell whether the Fox Tribe will regret it afterwards.

So Chen Yunhao just mentioned it, and Linghu Yuan agreed very readily. This is a typical case of not giving up until you see the rabbit!

"Fellow Daoist Chen, be prepared. That Crab Monster has merged with his former self..."

After teaching the art of spirit appraisal, Linghu Yuan should get down to business. He had invited back the noble person he had calculated and given him the benefits in advance. He should know whether he could be sure of what would happen next, so as not to end up with nothing.

"I understand. Fellow Daoist Linghu is worried, so I'm here to show you what I'm capable of..."

After a cup of tea, Linghu Yuan left with satisfaction. He immediately summoned his disciples and rushed to Blue Moon Lake overnight to resolve the troubles in his heart as soon as possible.

The Linghu family acted very quickly. They only prepared for one day and set off at night.

The Spirit Fox family is a rare and very intelligent race among the demon race. They are particularly good at learning, and especially love to learn from humans.

Just like the mountain protection formation of Linghu Valley, it was learned from the human race, and even the means of transportation this time were the flying boats commonly used by humans.

However, Xuanbing Province lacked materials for refining weapons, and the Spirit Fox Clan did not learn how to refine the techniques, so the flying boats they refined were too crude and barely reached the level of low-grade magic weapons.

But even so, the skills of the Spirit Fox Clan are unique in Xuanbing Province, and many demon tribes are willing to trade with them.

The flying boat is too crudely made, so its flying speed will naturally be much slower, so we have to set off early. After all, the journey is tens of thousands of miles.

It is more than 20,000 miles from Linghu Valley to the Blue Moon Lake, but their destination is on a large island in the lake, and it is another 20,000 to 30,000 miles to go deep into the lake.

So the total distance is about 40,000 to 50,000 miles. At the speed of the flying boat, it will take at least one night to fly.

The Spirit Fox Clan can be said to have gone out in full force on this trip. Except for the five elders, all those above level three were dispatched, with the attitude that if they didn't succeed, they would die.

Even if all of them were mobilized, there would only be more than a thousand of them, big and small, which was already a big force in this bitter and cold land.

More than a thousand Spirit Fox tribe members boarded five medium-sized flying boats, while five Spirit Fox tribe elders and Chen Yunhao shared one flying boat.

Moreover, this flying boat was Chen Yunhao's Aurora Boat, which really allowed several elders of the Spirit Fox Clan to experience what a spiritual weapon was.

The one who was staring at him greedily was almost drooling, looking like he had never seen anything good before.

Although the Spirit Fox Clan is considered a large family in Xuanbing Province, they can only be said to be local rich people in a remote area, and are not on the same level as the wealthy people in the Immortal City.

Besides, Linghu Valley is at least 50 million miles away from the human territory. Perhaps the ancestors of the Linghu tribe had contact with humans and learned formations and refining equipment.

However, the current fox clan has never seen the human race, so of course they have no chance to come into contact with treasures above spiritual weapons.

"Like it?"

Chen Yunhao smiled.

“It’s really good stuff…!”

Linghu Yuan reached out and touched the flying boat. What he said was true. Humans were still the smartest people in this world.

"I'll give you one...!"

As Chen Yunhao was speaking, he flipped his hand and in his palm appeared an Aurora Boat the size of a palm.

Although Chen Yunhao only has this kind of flying boat, he has an unlimited number of them.

Now that he had obtained what he considered to be a great opportunity from the Spirit Fox Clan, giving them a flying boat was nothing.

"this……!"

Linghu Yuan hesitated for a moment. After all, he was the elder of the clan and had to refuse for the sake of face.

But think about it, face is worth a lot of money, don’t miss it.

So Linghu Yuan figured it out in an instant and reached out to take the Aurora Boat. This item could definitely be used as a future inheritance for their family.

Everyone did not rest completely along the way, but communicated with each other.

Chen Yunhao had a better understanding of Blue Moon Lake, which made him feel more at ease and no longer had to worry about any subsequent troubles caused by this incident.

After this matter is over, Linghu Yuan will bring a large amount of property to shut up the old monster Qingyu, so even if it knows that some humans are involved in this matter, it will not pursue it anymore.

The Spirit Fox Clan had considered everything carefully, so Chen Yunhao felt relieved.

He also learned that the Blue Crab Clan in Blue Moon Lake, in addition to the Crab Monster, also had three elders who were at the level of Lianxu and tens of thousands of disciples, which made them quite powerful.

Before the Crab Monster merged, the Blue Crab Clan could at most tie with the Spirit Fox Clan, but this time it was different.

The Spirit Fox Clan decided to take down the Blue Crab Clan in one fell swoop and kill them all, so that they could dominate the Blue Moon Lake for a long time. This was a very rare opportunity.
