With Lin Yuan's current strength, facing the black panther in the middle stage of foundation building, it was very difficult, and he had to use the power of the Fu Seal to kill him.

It is conceivable that if he is facing the Tiger King in the late stage of foundation building, he will naturally be even less of an opponent.

But fortunately, the Tiger King should not have advanced to the late stage of foundation building now.

Moreover, the spiritual mountain where Lin Yuan is located is located in the middle of the territory of the demon race and the human race, and it is a very dangerous area, usually neither humans nor demon beasts dare to approach easily, and only Lin Yuan and the monkey king did not know about it before, so they dared to settle down here.

In other words, the demon beasts of the Ten Thousand Demon Valley may not be able to find this place for a while.

And before that, Lin Yuan still had some time to prepare.

After asking about the strength of the Ten Thousand Demon Valley, Lin Yuan asked some more questions, and then stuffed the black panther's divine soul into the white vial.

The soul of the demon beast in the middle stage of foundation building is a very precious treasure, Lin Yuan is reluctant to destroy it at will, and must be well collected.

After that, he began to check the space ring of the wildebeest and the panther.

In the space ring of the wildebeest, Lin Yuan found a few more talisman seals, as well as a batch of valuable cultivation resources.

But the most important thing is not these, but a book of talisman making!

According to the records in the classics, the runes are also divided into high and low levels, from low to high, in order, first-level runes, second-class runes, etc.

If you want to subdivide, then each level of rune seals can be divided into beginner, intermediate, high-level and other grades.

Like the Vajra rune and blood spear rune used by the wildebeest before, as well as the stealth rune used by the black panther, they are all second-level runes, but the Vajra rune can only be regarded as a second-level intermediate rune, while the blood spear rune and the invisibility rune are both second-level high-level runes, and as for the Shenxing rune that can increase speed, it is only a second-level beginner rune seal.

In addition, it should be noted that the same kind of rune seal, because of the level of production, as well as the quality of the materials used, the final grade of the rune seal is also different.

For example, if the second-level beginner-level magic talisman is made better, it may also become a second-level intermediate, second-level high-level, or even a third-level rune.

It's just that the higher the grade of the sigil, the higher the level of crafting and crafting materials required.

The book that Lin Yuan obtained only recorded the production methods of the first-level and second-level rune seals, as well as some of the unfinished third-level rune seal production methods.

But even so, Lin Yuan was very happy.

Because, the first-level rune seal corresponds to the existence of the qi refining period, while the second-level rune seal corresponds to the existence of the foundation building period.

In other words, if he can make some more second-level high-level talismans, then even in the face of the existence of the late stage of foundation building, he may be able to have some self-preservation ability.

Now, he already has a way to make a talisman seal.

And he also has the raw materials such as animal skins and blood sand needed to make the talisman.

Therefore, in the future, he can completely make a large number of runes.

After looking at the wildebeest's space ring, Lin Yuan began to check the black panther's space ring again.

In the black panther's space ring, there are also many precious cultivation resources, and the value is much higher than the things in the wildebeest space ring.

It's just that there is nothing strange in his spatial ring, so Lin Yuan only took a cursory look at it and put it away, leaving only a black vial.

In this black vial, there were some red pills, which were the healing pills that the black panther had taken before.

Lin Yuan was caught by the black panther in the previous battle, although the injury was not serious, but it also needed to be treated, otherwise it would be very uncomfortable, so he swallowed a red pill, and then directly lay down in the white pool to rest, the power of this mysterious pool of water also has a healing effect, which can speed up the repair of his injuries.

While resting, Lin Yuan also roasted some wildebeest meat and gnawed it in a big gulp.

The flesh of this wildebeest is a great tonic, which can not only strengthen his physical strength, but also replenish the essence and blood that he has lost before.

......

Time flies.

In the blink of an eye, it was the early morning of the next day.

At this time, in the Valley of Ten Thousand Demons.

In a grand palace, the male lion of the Lord of the Second Valley, dressed in golden armor, was frowning, pacing back and forth, looking very anxious.

His third brother, Black Panther, has been out for a day, and has not yet returned, and there is no news of him, how can he be more than hearted?

"The third child won't have an accident, right? No, the bull demon he went to track only had the cultivation in the early stage of foundation building, how could it threaten him? Or did he meet a human powerhouse? Or did he meet a strong man from the Heavenly Demon Peak and the Demon Beast Forest?"

"Second child, why are you so anxious?" At this moment, a majestic voice suddenly came from the depths of the palace.

"Big brother, third brother, I'm afraid something has happened!" the male lion trembled and hurriedly said.

He knew that it was the voice of his eldest brother, the Tiger King.

"What can happen to the third brother?In this Ten Thousand Beasts Mountain Range, who else can threaten him besides you and me?" the Tiger King's voice sounded again.

"Big brother, the third brother went out yesterday, and he should have come back a long time ago, but until now, I haven't seen his figure, I'm afraid he won't be able to come back!" said the male lion with a frown.

"Don't panic, maybe he has encountered something else, send someone out to find it first, now I am breaking through to the critical juncture of the late stage of foundation building, no matter what it is, don't bother me anymore, everything will wait until I get out of the customs, let's get out!"

"Yes, big brother!" the lion was slightly startled, and hurriedly replied respectfully.

Unexpectedly, the eldest brother Tiger King has already begun to try to break through to the late stage of foundation building, perhaps, soon, in the Valley of Ten Thousand Demons, there will be a powerful existence in the late stage of foundation building.

When the time comes, the demon clans of the Heavenly Demon Peak and the Demon Beast Forest will not dare to provoke them easily.

It's just that in this way, for a long time in the future, the boss of the Valley of Ten Thousand Demons may still be the Tiger King, and if he wants to surpass the Tiger King and regain the glory of the grassland king, he doesn't know that he will have to wait until the Year of the Monkey and the Horse Moon.

Then, the lion withdrew from the main hall, closed the door of the palace, and sent the little demons of the Valley of Ten Thousand Demons to search the mountain.

......

At the same time, after Lin Yuan rested for a night, he had almost recovered, and the injuries on his body had basically healed, and then, he only needed to slowly recuperate.

Early the next morning, he left the Spirit Mountain, went to a volcano not far away, repaired the spirit weapons damaged in the previous battle one by one, and added a special ore obtained from the wildebeest and the black panther, and once again strengthened and improved the power of various spirit weapons!
