Lu Yan glanced up at the demon bear, and then said with a smile: "You have a share of the credit this time, and I will get you barbecue meat to eat when I go up."

As soon as he heard the barbecue, the excitement on the demon bear's face became stronger, and he roared again, "Roar.. Roar. ”

Looking at the demon bear's excitement, Lu Yan smiled and shook his head, and then leaned down to continue picking up the dirt. Soon, Lu Yan cleaned up all the dirt next to the spar, revealing its full face. Lu Yan carefully took out the spirit stone.

Feeling the rich energy fluctuations emanating from this spirit stone in his hand, Lu Yan was extremely excited in his heart. Judging from the energy fluctuations, the grade of this spirit stone does not seem to be low, almost as rich as a medium-grade spirit stone, but it seems to be a little bit worse.

"Hey, it's a big deal" Lu Yan sighed in his heart, just the most superficial spirit stone is already of such a good grade, I really can't imagine what kind of grade the spirit stone hidden deep below has not been excavated, it is estimated that there should be a top grade, he boldly guessed.

Carefully putting this spirit stone into the space ring, Lu Yan took the long sword and continued to dig down, he wanted to see what sample-level spirit stone he could find in the end this excavation.

Soon, along the place where the first spirit stone was found, Lu Yan dug out more than a dozen spirit stones of different grades one after another, and several of them were medium-grade spirit stones, which made Lu Yan more and more excited.

After about half an hour or so, Lu Yan suddenly found that there was no single whole spirit stone, but a large piece of it that was connected together, and a thick aura emanated from it.

Whew, Lu Yan, who was already sweating at this time, wiped the sweat on his face with his hands, exhaled a breath of turbid air in his mouth, and looked at the spirit stone mines connected in front of him, his eyes flashed with excitement.

Although he had already seen that it was a city connection, and Lu Yan was already convinced in his heart that this should be the spirit stone mine, Lu Yan sighed in his heart, because the depth at this time was about five meters above the ground.

But at this time, Lu Yan, who had already been filled with the excitement of discovering the spirit stone, rolled up his sleeves, and then continued to dig up. However, this time he did not dig down, but continued to clean the dirt from the huge pieces of spirit stones connected to the surface. The dirt that had been dug up was constantly collected by him into the spatial ring.

Fortunately, he now has a space ring, otherwise he really wouldn't dare to imagine how he could dig these spirit stones if he was alone, it would be very troublesome to deal with these excavated soils alone.

After about half an hour, the mud pit that was originally only one zhang in diameter became larger to the size of a radius of three zhang at this time, and many spirit flowers and spiritual grasses that had just reached maturity were also included in the space ring by Lu Yan. Fortunately, these spirit flowers and spiritual grasses have not been picked for a long time, so they have basically reached the maturity stage, otherwise Lu Yan must be distressed when they are suddenly picked like this.

At this time, Lu Yan's feet were all yellow and misty, all of them were spirit stones, and before he could see the edge, a stream of rich spiritual energy gushed out, and the spiritual energy in the space within a radius of three zhang was dense, like a fairyland.

Those spiritual qi did not need to be actively absorbed to drill into the body through the pores around the body, and the Tianyan Jue in Lu Yan's body also worked silently, constantly refining and absorbing these spiritual qi. After a while, Lu Yan felt a feeling of swelling in the dantian, and his heart was overjoyed.

Putting down the long sword in his hand, Lu Yan stopped digging and stood there straight, his eyes closed, and the whole person was immersed in the refreshing feeling of aura entering his body. While refining these spiritual qi that entered the body independently, Lu Yan thought about how to make good use of this treasure.

Ever since he met the powerful mysterious uncle in Longyan Cave and the seemingly weak but powerful elder in the Martial Pavilion, Lu Yan has been constantly analyzing the mystery of his father's disappearance back then, which has made him discover a lot of things.

The first time he was in Longyan Cave, Lu Yan didn't know that there was such a strong person in the Lu family, according to Lu Yan's estimation at that time, it was at least the innate realm, and it was still a very strong kind. Because his father is in the innate realm, but the kind of momentum exuded by his father is not as strong as that of this uncle.

and then the elder in the Martial Pavilion behind him, which made his inner guess even stronger. Although the aura on that elder's body was only a flash, Lu Yan was sure that that aura was not much worse than that uncle in the Longyan Cave. This shows that there are at least two great masters of the Innate Realm in the Lu family, and this powerful strength is completely enough to dominate the entire Longzhou Mansion. But the actual situation is that although the Lu family claims to be the number one force in Longzhou Mansion, it is excluded by other families everywhere, and even the Li family, the last of the four major families, dares to oppose the Lu family everywhere on the bright side.

"Could it be that there is also an innate realm among these families?" Lu Yan guessed in his heart.

"No, they shouldn't have the existence of the Innate Realm, otherwise the Li family's domineering style would have been exposed long ago!" Lu Yan shook his head and quickly denied this judgment.

"But why does the Lu family have such a master but does not show his ambition to dominate the entire Longzhou Mansion? With Lu Yan's understanding of his grandfather, who is bent on restoring the peak of the Lu family back then, he must hope that the Lu family can dominate the entire Longzhou Mansion!"

"With such strength but not using it, is it hiding something, or is it to hide something?" Lu Yan kept guessing in his heart.

"Could it be because of him?" Lu Yan suddenly thought of a possibility in his heart, especially when he thought of his father's disappearance and his attack in Longyan Cave, which made him feel that there was such a possibility.

"Yes, it's that mysterious person, and only that mysterious person can make the family hide their strength like this1" Lu Yan affirmed in his heart.

Otherwise, Lu Yan couldn't understand why after his father was attacked and disappeared by several mysterious congenital realms, he actually dealt with the news that Lu Yi's father desperately ran back to report, and specially told Lu Yi to be careful. At that time, they must have known that there was a mysterious enemy hidden in the family. And it must have been because the whereabouts of his father and others were suspected of being leaked from the inside, which made them suspicious.

But it's been more than three years, almost four years, and there are still no results. Even the uncle in the Longyan Cave and the elder of the Martial Pavilion were deliberately hiding their strength, which also proved that they must have discovered something, and it must have something to do with this mysterious person. Being able to dispatch seven or eight innate realm martial artists to carry out a sneak attack on his father and others shows that there must be a force behind this mysterious person, and this force makes the Lu family feel a deep crisis.

Comprehensive analysis, the reason why the Lu family hides the news of the martial artist of the innate realm must be that they are afraid of being known by this mysterious force, which will bring an unpredictable crisis to the Lu family.

Thinking about it carefully, Lu Yan felt that he had fallen into a deep whirlpool. But what Lu Yan couldn't understand the most was why that mysterious person would attack him in Longyan Cave, after all, he was just a weak person who couldn't even practice qi mirrors at that time.

Lu Yan felt that the biggest possibility was that this mysterious person or this mysterious force had been hiding for so many years after his father's disappearance, and the reason why there were no more mysterious movements must be that he was looking for something. I searched for my father before, but I didn't find it, so I transferred it to my own place.

Because according to normal thinking, if what they want is not in their father, then it is only in themselves. Because everyone knows that Lu Tao only has two sons, the eldest son has followed the strong man out to train many years ago, and the rest is himself, and there must be something left for the youngest son. This would also explain why the mysterious man would sneak up on him at the critical moment of his breakthrough.

And as for what the mysterious man was looking for, Lu Yan already had the answer in his heart.

"That's the Evergreen Formula, because the only thing my father left to him is the Evergreen Recipe, which can be said to be precious," Lu Yan analyzed in his mind little by little.
