This also makes it much more difficult to improve the level of the Netherworld Whip than ordinary weapons. However, after using the Netherworld Whip, its attack power is very considerable. Especially the six times the group attack skill hurricane array, under the wielding of the eighth-level warrior Shari, the wolf warrior of the werewolf village chief level could not hold on for more than ten seconds and was hanged alive!

Although the unexpectedly obtained medium-grade Xuan copper and bloodstones were not enough to raise the Netherworld Whip to the seventh grade, after Lin Zhou confirmed with the ridicule system, he found that the medium-grade Xuan copper and bloodstones in his hand were enough to raise the sixth-grade Dragon-Slaying Soul-Breaking Treasure Kitchen Knife to the seventh grade!

This is a real surprise!

Of course, these medium-grade Xuan copper and bloodstones can also upgrade the sixth-grade Netherworld Bow to the seventh-grade. Unfortunately, the mockery system can only use mockery experience value to increase the grade of its own kitchen knife, and cannot help these non-system-produced weapons. Lin Zhou did not know any weapon refiner, so the right way was to upgrade the Dragon-Slaying and Soul-Breaking Treasure Kidney to Level.

After Lin Zhou collected the other captured Qiankun bags, he actually collected all the other auxiliary materials for upgrading the sixth-grade kitchen knife to the seventh-grade kitchen knife, but there was only one raw material.

This means that if Lin Zhou fails to upgrade, there will be no chance for a second time.

Therefore, the lucky charm I got when I was promoted before is about to take action.

"Are you sure you want to sacrifice and refine the sixth-grade Dragon Slaying and Soul-Breaking Sword?"

"Sure."

"Now start the sacrifice..."

“Materials: Complete…”

"Experience value: no blessing of experience talisman..."

"The mysterious energy in the body: all..."

"Blessings of Lucky Talisman..."

"In the sacrifice..."

Lin Zhou looked extremely serious and waited for the verdict of the ridicule system. The Dragon-Slaying Soul-Breaking Sword is his main weapon!

Although the lucky charm was used, according to the previous experience, it is still impossible to guarantee that the sacrifice and refining can be 100% successful. For example, when the Netherworld Arrow was comprehended, although it was successful for the first time, after washing it off, it only took three times before successfully comprehending the Demon-Devouring Cone again.

About ten minutes later...

"Congratulations! Successful sacrifice! The sixth-grade dragon-slaying soul-breaking sword is promoted to the seventh-grade dragon-slaying soul-breaking sword!"

After hearing this prompt, Yin Linzhou breathed a sigh of relief, and then he looked at the Dragon-Slaying Soul-Breaking Sword that had reached the seventh grade with joy.

After the Dragon Slaying and Soul-Breaking Sword was promoted to the seventh grade, the bronze color on the surface became crystal clear, and the appearance of the sword body changed a little again, increasing by three centimeters and the back of the knife became thicker. The weight in his hand increased a little more, giving him the feeling that if he advanced again, the kitchen knife would sooner or later become a real dragon-slaying sword that looked crazy and cool!

On Shali's body, Lin Zhou also found a special Qiankun bag.

It is the Qiankun bag containing the Jiuyou Tian Sword Formation.

When Lin Zhou found bundles of third-grade Netherworld Swords inside, he thought it was a standard weapon brought by Shali to those disciples. Later, after seeing the nine-barrel flag and a booklet for setting up the array, he realized... This was actually the kind of protective formation that only the big sects could sacrifice and refine!

This surprised Lin Zhou. You must know that it is not easy to build such a protective array, and it is even worthless. Even the big family in the imperial capital cannot afford one. Even if the financial resources are enough, there may not be a large sect in Zhongtian Continent willing to help refine this protective array.

After all, these protective arrays contain some secrets of the sect's martial arts. If you beat them to give them to others, it means that someone may study the method of breaking the array, which will eventually affect the safety of the sect. Therefore, this thing is completely priceless.

According to the instructions of the booklet, this protective array is a reduced version of the mountain protection array of the Demon Moon branch of the Netherworld Sect. It can protect a small hill at least, and the maximum can protect the entire mountain! Of course, the larger the protection range, the smaller the power of the protective array. According to the above description, Lin Zhou estimated that if he used it to protect the entire Zhenlong Mansion, the power would almost not decrease, but if he protected the entire Linjiabao, the power would drop to one-third of the original.

Zhenlong Mansion is located in the center of Linjiabao, covering an area of ​​one-fifth of the entire Linjiabao. If the Lin family really has a disaster in the future, Zhenlong Mansion will be enough to accommodate all the Lin family members. So after Lin Zhou studied the Nine Nether Heavenly Sword Formation, he immediately had the plan to use it to protect Zhenlong Mansion.

In this way, in the future, the Lin family had already established an invincible position as long as the Jiuyou Tianjian Formation was present in the battle with other families in the town.

There are some detailed operation instructions for this formation in the booklet. The higher the cultivation level and the stronger the soul, the more powerful the warriors will sit in the formation and hold the main formation flag and control the formation, the greater the power of the formation.

Lin Zhou didn't know at this time that the Jiuyoutian Sword Formation was actually a flawed sword formation.

After putting down the sword formation, Lin Zhou began to think carefully about how to use existing resources to improve his strength again.

He still has two lucky charms in his hand.

Lin Zhou wanted to wash away these two lucky charms five times, so that the power of the kitchen knife could be increased upward...it would be more than seven times.

Then, Lin Zhou also wanted to wash off the wooden armor. If he could comprehend four times the Stone Kaede or five times the Vajra Armor, his defense would be able to compete with the eighth-level warrior who had not comprehended the level five mysterious armor technique!

And Liu Kun also wants to have a throat-sealing cut!

You should know that you have learned a powerful body technique like Nijidao. Liu Kun's throat sealing and cutting almost opened his throat with the Netherworld dagger! The key book I found in Liu Kun's Qiankun bag is a book of the experience of a powerful man from the Netherworld Sect who has been skilled in using the Netherworld Sect for decades of experience!

Lin Zhou estimated that once he successfully understood the throat sealing and learned the key points, he would probably have an extra powerful comprehension technique like the Demon Eater Cone, which can implement one-hit kill on his opponent! Now that he has so many more ridiculous experience points, why not use a lucky talisman to wash away the Thousand Blade strike and re-understand it?

"Xiaofeng, if I wash off the Thousand Blades and use a lucky talisman to comprehend the Blood Blade Technique, will I understand the Throat Seal?" Lin Zhou consulted Xiaofeng. If the probability is too low, he would not consider trying.

"There is a certain possibility. Since you have a special liking for this comprehension skill, when you comprehend this comprehension skill, you will greatly increase the chance of understanding this comprehension skill when you comprehend it." Xiao Feng said to Lin Zhou.

"Just like the hurricane array I understood just now?" Lin Zhou's eyes lit up. When he was comprehensive about the Netherworld Whip Technique, he was indeed constantly muttering the hurricane array in his heart, but it really made him understand the hurricane array.

This throat cut will have the same effect, right?

Lin Zhou, who was not very determined to wash away the Qianbian Hit, suddenly couldn't help it.

After thinking for a while, Lin Zhou resolutely made a decision to wash off the Thousand Blades and strive to understand the Throat Seal!

Some low-level martial arts will not be very powerful even if they understand them, and they are not even as powerful as the ordinary attack of the seventh-grade kitchen knife. However, powerful martial arts like sealing the throat are worth paying a certain price on them.

After upgrading and comprehending the hurricane array of the Netherworld Whip Technique, Lin Zhou still had more than 18,000 taunt experience points, which was enough to comprehend. However, there were only two lucky charms. Lin Zhou decided to use one to use it to wash it off and re-encrypt it, and the other to use it to wash off the Qinglong Slash or the Wooden Dao Armor depending on the situation.

As for whether to wash away the Qinglong Slash or the Wooden Dao Armor, Lin Zhou decided to re-understand the throat seal before making a decision.

Wash it off at 2000 points, and realize it again at 2000 points, and the lucky charm also blessed it...

"Now start to understand the Bloodblade Technique..."

"Intellect..."

Lin Zhou began to silently recite the three words "Crossing the throat".

"Congratulations on your successful understanding!"

Lin Zhou's heart was raised to his throat... It was successful! At least he did not understand it failed... But don't use any other comprehension skills! It must be a throat-sealing cut! Otherwise, it will be in vain!
Chapter completed!
