I'm invincible since the end of the world

"Why doesn't this archery have a perfect realm?" Lin Xinghai asked immediately.

"Because the sage who created this archery was only a Rule Realm expert. According to the notes he left behind, the perfect realm of the Thunder Demon Breaking Archery requires a Heaven and Earth Realm expert to perform, so he was unable to create it due to the realm limit." The female elf explained immediately.

Lin Xinghai's eyes flickered. It was obvious that the upper limit of this archery was much higher than he imagined.

"Okay, I understand. Please help me exchange the full version of this archery book." Lin Xinghai nodded.

The female elf moved her mouth, but she didn't say anything in the end.

And Lin Xinghai thought about it, picked up another book, and asked: "How many contribution points do I need to exchange this 'Five Elements Linked Arrows'?"

The biggest feature of this Five Elements Linked Arrows is that it is very inclusive and easy to use.

In addition, it has another feature, that is, if there are 5 archers who all learn this skill, they can set up a five-element formation, and through the blessing of the battle formation, the power of archery can be raised to a higher level.

Obviously, Lin Xinghai chose this archery for the human race. It is easy to get started, and it is powerful after triggering the battle formation.

The only disadvantage is that after the battle formation is formed, it cannot be moved at will and can only be used as a turret, but this is not a problem for the human race.

"Uh..." The female elf didn't know why Lin Xinghai chose an extremely difficult one and then an extremely easy one.

But she still quickly replied: "This archery book only needs 100,000 contribution points for the whole book."

"What if it is only exchanged for the first two levels of archery?" Lin Xinghai continued to ask.

The first two levels of archery correspond to the body shaping realm and the god and demon realm respectively.

As for the rule realm, Lin Xinghai will not consider it for the time being.

Now the number of rule realms is limited, not to mention that even if there are really 5 people, it is unlikely to gather them all together, but to disperse the country to guard the abyss passages everywhere.

If you really need it later, you can redeem it again.

"Then it only takes 20,000 contribution points." The female elf replied quickly.

"Okay, then I'll take both of them, you remember them first." Lin Xinghai said, and finally walked to the bookshelf where the perception secrets were stored.

There were much fewer books here, less than 100 books.

This also proved from the side that the perception secrets were precious.

Lin Xinghai immediately checked them one by one.

With his perception strength, he could read books at a glance and remember everything he saw.

So after a while, he read all the introductions of these 100 books.

There are three kinds of secrets that he needs, which can imprint his rule power and pull it back after the battle.

They are the basic version, the complete version and the advanced version, all called the rule imprint secret.

The principles of these three secrets are similar, but the degree of sophistication is different, and the results directly caused are also very different.

The basic version of the rule imprint secret technique is the easiest to practice, but it can only be used after the battle is over, and the traction speed is not fast.

It basically takes 3 days to pull back all the rule power that has left a spiritual imprint, and the distance cannot be too far from the battlefield, at least within 500 kilometers.

As for the complete version of the secret technique, it is much more efficient, and it can pull back the rule power that has been imprinted in about 1 day.

And the distance is much farther, which can reach more than 3,000 kilometers.

As for the advanced version of the secret technique, it is also the most difficult. It is no longer limited to post-war traction. It can recover the rule power while fighting.

And the effect is also much more terrifying. When the rule power is exhausted, it can be completely restored in up to 6 hours. As for the distance, it can reach a terrifying 10,000 kilometers.

Of course, with such a big difference in effect, the difficulty of practice is naturally very different.

The difference in the difficulty of practice between the first and second types is about 50 times.

Even the prerequisites are not something that ordinary people can have. The requirements for the total amount of rule power and the ability to control rule power are extremely high.

So ordinary people can only choose between the first and second secret arts.

After thinking for a while, Lin Xinghai asked about the price.

Soon he got the answer from the female elf, 100,000 contribution points for the basic version, 200,000 contribution points for the complete version, and 500,000 contribution points for the advanced version.

Of course, this means buying the whole book.

There are 4 levels in the rule brand secret art, corresponding to entry, minor success, major success and perfection.

If you only buy the first two levels, the price will be much cheaper.

So Lin Xinghai thought about it and bought the entire advanced version of the rule brand secret art, which he would use for himself.

He only bought the first two levels of the basic version and the complete version.

In this way, he only needs 30% of the total price to buy it, that is, 30,000 and 60,000 contribution points.

If you add the complete Heavenly Thunder Demon Breaking Arrow Technique and the Five Elements Linking Arrow Technique prepared for humans, the total is 1.08 million contribution points.

Among these, 1 million contribution points were spent by Lin Xinghai for himself.

On the human side, only the first two levels of secret techniques were purchased, which did not cost much.

After calculating the price, Lin Xinghai also felt a pain in his flesh. If he hadn't treated the elf leader Dracula today and obtained 1 million contribution points, he would never have been able to come up with this money.

Counting the money for treating the strong men of the dwarves and elves in the past two days, the total was only 1.32 million contribution points.

"Forget it, money is used for spending." Lin Xinghai comforted himself in his heart.

Then he took all the skills and secrets he had selected and handed them to the female staff.

Three minutes later, there were only 280,000 contribution points left in Lin Xinghai's account.

Of course, he also had 5 more books in his hand.

After checking and confirming that there was no problem, Lin Xinghai immediately put these skills and secrets into the storage space.

Then he looked at Lina who was waiting on the side.

"Lina, next I'm going to go to the dwarves and ask them to help make a hard bow. If you have something to do, you can go and do your own things first." Lin Xinghai said.

He already knew the way to the elves, so he didn't need them to lead the way.

"I'm fine." Lina shook her head. In fact, the most important task assigned to her by the Great Elder was to find a way to give Lin Xinghai all kinds of conveniences. How could she leave at this time?

As she said that, she immediately led the way in front and guessed, "Elder Lin, you went to the dwarves to forge a hard bow. Are you planning to practice the Thunder Breaking Demon Arrow Technique?"

When Lin Xinghai exchanged the skills just now, he did it directly in the hall. Of course, she saw it.

"Yes!" Lin Xinghai naturally had nothing to hide about this. In fact, he planned to use the remaining 280,000 contribution points to forge a good spiritual weapon.

"If that's the case, I have a suggestion." Lina said hesitantly.
