As soon as the Blood Soul Knife was thrown into the purple gold bowl, Zhang Nan's mind immediately had some more information, which made him almost faint.

"Blood Soul Knife, the best treasure, the first upgrade, requires 19,990,000 spirit stones, and the success rate is 100%. Please put in the spirit stones!"

This information is too amazing, the first upgrade actually requires 19.99 million, if the success rate is not 100%, Zhang Nan will definitely feel even more distressed about this money, he has just become rich and handsome, and the things have not been warmed yet, which will be spent.

Zhang Nan's flesh hurt incomparably, he frowned and closed his eyes and put the spirit stone into it, and immediately received the information of whether he was sure of the upgrade.

"Sure!"

As soon as his eyes were closed, Zhang Nan immediately sent out a thought, and as soon as this thought was transmitted, he saw a burst of light flashing in the purple gold bowl, which was extremely dazzling, so that Zhang Nan couldn't help but close his eyes.

"The upgrade is complete! The Blood Soul Knife is now a low-grade holy weapon, with the performance of increasing attack power by five percent, whether to upgrade for the second time, the second upgrade requires 200 million low-grade spirit stones, and the success rate is ninety percent!"

The information from the purple gold bowl made Zhang Nan happy and painful, the upgrade was really successful, it became a holy weapon, and it also had the performance of increasing the attack by five percent, but what made him speechless was that the next upgrade not only reduced the success rate, but the spirit stones needed actually became 200 million low-grade spirit stones, that is to say, even if it is replaced with a medium-grade one, it will cost two million, and if it is replaced with a high-grade one, it will cost twenty thousand.

"Your sister, this thing is a loser!"

Sighing helplessly, Zhang Nan could only smile bitterly and take the Blood Soul Knife from the purple gold bowl.

As soon as his mind moved, the blood soul knife flew out of the purple gold bowl in an instant, and the whole body was glowing with blood-red light, and a blood-red pillar of light rushed straight out, if it wasn't for the blockage of the cave roof, that kind of brilliance would definitely pierce the sky, a kind of king's domineering spirit appeared from the knife body, and the fluctuations around the knife body were also several points stronger than before.

"Buzz!"

Suddenly, the Blood Soul Knife emitted a slash sound, as if it was also very excited to enter the ranks of holy weapons, and the entire blade also trembled slightly.

It was only a slight tremble, but it was a vision, and the entire mountain peak couldn't help but tremble, and a kind of arrogant fluctuation made the aura between heaven and earth become a little irritable, and this extremely arrogant fluctuation instantly spread like the mountain.

"Poof!"

In Nangong City, there were many cultivators who were disturbed at this moment, and the sudden riot and disorder of the aura caused them to spurt out a mouthful of blood, and they almost went mad.

"What's going on?"

"This... What's going on? Who did it? ”

Many people ran out, and some even had some anger, as soon as they flew out, they looked at the place where the fluctuations came from, and when they found out that it was the peak where the Six Dao Ancestors were located, they all shook their heads and smiled bitterly, thinking that only the most powerful Six Dao Ancestors here could make such a big movement.

"What's going on? Such a strong fluctuation came from the place where the master was. ”

Nangong Mu was naturally awakened, looking at the peak where Zhang Nan was, frowning, not knowing whether to go and see if he should go to see it, he was afraid that Zhang Nan would have something he didn't want him to see, but he was afraid that something would happen to Zhang Nan when he was cultivating.

Looking at Nangong Mu, who was frowning, Li Lu also understood what his son was worried about.

"Mu'er, let me go and take a look, I believe that your master will not have anything to do. ”

After thinking about it, Li Lu said, seeing his son nodding, Li Lu threw out a fairy sword with a movement, and immediately flew towards the peak.

Zhang Nan was also slightly stunned, he didn't expect that this Blood Soul Knife would be able to show such a vision when it was upgraded, it seemed that he was careless. So with a movement in his mind, he directly put the Blood Soul Knife into the space ring, and all fluctuations were eliminated at once, and everything was flat.

He walked out of the cave very leisurely, and at this time Li Lu had already come to the cave not far away.

"Are you alright?"

Seeing that Zhang Nan was intact, Li Lu couldn't help but ask with concern.

"Hehe, it's okay... I was thinking about a martial art just now, and then I tried it a little. ”

Zhang Nan showed a sunny smile and said very plainly.

"That's good... I'm afraid that something happened to your cultivation... You're fine... I'll go back first. ”

Although Zhang Nan's explanation was very pale, the kind of fluctuation just now was the fluctuation of martial arts, and that kind of fluctuation seemed to be invisible, just like the forcible interference of spiritual power on heaven and earth, which was obviously not caused by martial arts, but she would not ask, after all, her purpose was to see if Zhang Nan was okay, as long as Zhang Nan was fine, then she would be relieved.

After Li Lu finished speaking, he turned around and prepared to fly up and down.

"Ahem, you're not going to accompany me today?"

A sentence came from behind him, causing Li Lu's slender body to stop there in an instant, and Zhang Nan twice, once because the situation was forced, and once because he took the initiative, and this time, it was finally Zhang Nan who made such a request, which made Li Lu's heart finally have some comfort, and the real meaning is not to regret it, even if it is worth paying for him.

Turning around, Li Lu showed a sweet smile: "At night, Mu'er is still waiting for me to go back and tell him about you at the bottom of the mountain, and he is also worried about you... ”

After speaking, the beauty smiled sweetly again, her figure moved, and flew down the mountain.

"Hey... It seems that the remaining months are only a few months to study the drunken fist of the old drunkard, and maybe there will be a lot of gains!"

Zhang Nan thought about it, and he couldn't indulge in all the rest of his time to be obsessed with women, and felt that the drunkard's boxing method was quite interesting, so he was ready to study and study, so that time might pass a little faster.

Three months passed quickly, except for the occasional mess with Li Lu, Zhang Nan was obsessed with studying the drunkard's boxing method, in order to study this boxing method and obtain some of the mystical essence, Zhang Nan drank a lot of wine, and often drank himself to the point of dizziness.

Three months later, it was less than a month before the opening of the Ten Thousand Ghost Abyss, and Zhang Nan was ready to go.

This time with Zhang Nan, there were four protectors of the Nangong family, among which there happened to be Lao Jin, Cuihuaer, an old drunkard and a middle-aged man who Zhang Nan was familiar with, who looked a little honest, Zhang Nan remembered that he had also drunk with this person, called Gao Yang.

"Let's go!"

Zhang Nan waved his hand, his heart was full of excitement, he had been rubbing his hands for so long, this time... Finally about to break out, he raised his combat power to an extreme, and from a rich man to a poor man in an instant, just to obtain the Great Dao Fruit and the Soul Shell, he was determined to obtain, with these two things, that is to buy the Dan Spirit Realm, and it is also the most difficult difficulty to complete the cultivation of the Six Dao Decisions.
