After the transaction was completed, the young man surnamed Leng stared blankly at Lin Quan's distant figure and was speechless for a long time.

"Brother Tianhu, what kind of fire spirit mosquito is really so good, why would you be willing to exchange such a precious classic?" The girl who had been standing quietly on the side finally couldn't help but ask the doubts in her heart.

"Sister Yun, when have you seen your brother suffer?" The young man surnamed Leng smiled slightly, looking at the jade box in his hand, with an unfathomable expression on his face.

"However, the number of these fire spirit mosquitoes is so small, I don't know how many years it will take to cultivate them to the point where they are useful. Besides, this mosquito is particularly afraid of ice spells, and such an obvious weakness will also make it very badly targeted by those who have a heart. ”

"Haha, I didn't expect Yun Mei to have such an achievement in the way of insect control. The young man surnamed Leng first stroked his palms and laughed, and then smiled mysteriously: "Do you really think that I will pay two precious tomes for five Fire Spirit Mosquito Eggs?"

"What......? These aren't fire mosquitoes?"

"If I'm not mistaken, these five eggs are supposed to be the rare blood mosquitoes. I don't know where this Jin Daoyou got it, but in the end, it was cheaper for our Leng family. ”

"Blood mosquitoes, is there such a species of mosquito spirit insects?" the girl was confused when she heard this, and no matter how she searched her intestines and scratched her stomach, she couldn't figure out the origin of this mosquito.

"Yes, the Blood Mosquito is a special spirit insect that is basically extinct. I believe that few people can know except for the heirs of big families who are good at the way of insect control. As for the characteristics of this mosquito, you will naturally understand it when you are qualified to practice the secret scriptures of the Leng family. Alright, let's pack up and rush back to the family immediately. I believe that the ancestor will be happy!" The young man surnamed Leng explained lightly and said no more.

"Yes, Brother Tianhu. The girl seemed to understand the rules as well, and after answering obediently, she began to pack up her things quickly.

While the girl was cleaning up the stall, the young man surnamed Leng glanced at the jade box again. sighed silently in his heart: Brother Jin, this time Leng can't stand you. Although the "Heavenly Tiger Record" and the "Blood Pact" that I occasionally obtained are very precious classics, these five blood mosquito eggs are even more valuable. Originally, I didn't want to bully each other, but for that big thing, in order to give my Leng family a chance to rise again, Leng could only go against his heart once.

After a cup of tea, the young man and the girl surnamed Leng disappeared in Tiemufang City.

Of course, Lin Quan didn't know anything about the blood mosquitoes. Thinking that he had gained a lot of bargains, he had already rushed back to the cave and began to study the two newly acquired classics. In fact, he had already noticed the abnormal performance of the young man surnamed Leng, but he didn't take it too seriously. In his opinion, it is only right to exchange five useless eggs for what he wants most at the moment, even if he suffers a little loss, it is nothing. Lin Quan had already thought about it, what good spirit insects would there be if they relied on the kind of non-flowing loose cultivators of the Yin and Yang Sanren, that kind of giant mosquito might still be able to show its majesty among the monks in the condensation period after a certain number, once the monks reached the Great Perfection or the condensation period, they should be useless.

"Records of the Heavenly Tiger" and "Blood Pact" are the names of these two secret arts. In order to save time, Lin Quan went directly to retreat for enlightenment as soon as he returned to the cave.

There is nothing too important in "Tianhu Records", all of them are a transcript written by the young man surnamed Leng himself. It mainly tells the information of hundreds of common demon beasts or demon insects, and also includes the information of more than ten kinds of second-order demon beasts and demon insects around Tiemufang City and Qianyun Mountain. The entire record does not record any methods for cultivating spirit worms, but the information on those demon beasts is clearly described, and it is also accompanied by beautiful drawings. This is a very practical thing for Lin Quan, who has hardly dealt with demon beasts and is about to go hunting in Qianyun Mountain. The only thing that's a bit of a pity is that there is no introduction to his pair of spirit silkworms in this "Heavenly Tiger Record".

As for the other "Blood Pact", it is indeed a contract secret technique used by ancient monks, as promised by the young man surnamed Leng. And after Lin Quan's comparison, it was found that this "Blood Contract Technique" should be a secret technique attached to some kind of clever bloodline exercises. In addition to the "Blood Pact", it also introduces several kinds of blood Dao magic powers or secret methods, but unfortunately, except for the part of "Blood Pact", which is still very complete, the other secret techniques are all incomplete, and they cannot be comprehended and cultivated at all. And the whole article of this blood path supernatural power is described in a kind of rare ancient text, and the content is very obscure. Even Lin Quan, who has a profound foundation in ancient writing, took nearly eight days to finally understand it.

It wasn't until Lin Quan fully comprehended the entire "Blood Pact Technique" that he realized that he had really picked up a treasure unexpectedly this time. According to the introduction of the exercises, this kind of contract secret method was also an extremely superior secret method even during the ancient monk period. Because the blood contract technique is a very domineering secret art, all kinds of spirit beasts or spirit insects cannot be dissolved for life once they sign a master-slave contract with the monk, and if the master falls, then the contracted spirit worm will definitely die. Therefore, any spirit worm or spirit beast that is contracted by such a secret method will not betray or rebel at all. Of course, this secret method also has certain flaws, otherwise even the young man surnamed Leng will not be willing to show such a precious secret method no matter how generous he is.

First of all, the conclusion of this secret method requires the arrangement of a special contract formation, which is still quite difficult for people who have not learned the formation technique, and the materials to be consumed to arrange the magic circle are also very precious.

The second is that no matter how good the potential of the contracted spirit worm is, no matter how noble the bloodline is, its cultivation will never be able to surpass the master in the great realm, so once the master can't advance, even if the contract is a powerful spirit worm, then it will never be able to advance.

Finally, the success rate of this secret method is extremely low, and it is often impossible to succeed in the contract more than ten times in a row. And after each failure, you have to spend a lot of materials to rearrange the contract circle. This huge consumption is a very heavy price for ordinary casual practice.

Lin Quan didn't care too much about these shortcomings, what he valued most was the incomparable compulsion of the Blood Pact Technique.
