The flying wild boar continued to surround Zhang Xiao's side, and no matter how hard he tried, there was no way to get rid of this difficult guy.

The boar was like a part of the void, untouchable, and had no way to inflict real damage on it.

But what is even more strange about Zhang Xiao is that although this guy has been haunting him, he has not posed any threat to him, as if he is just an eye-catching ornament, and it seems that he can also boost his energy.

"When the timer is up, the total principal and interest will be increased to 4034 pounds!" The flying boar made another sound.

Why? Why did you increase the value again? And it has improved so much all at once?

Zhang Xiao looked at the phantom boar beside him that had swelled to about the same size as himself, and found that the appearance of this wild boar was no longer as cute as before, but became a little hideous and terrifying, staring at him fiercely.

Forget it, leave it alone!

Zhang Xiao simply ignored this wonderful boar of the Nirvana Demon Emperor, and prepared to attack the Nirvana Emperor directly, anyway, this wild boar has no threat for the time being, even if it is really a trap, he has no way to eliminate this wild boar, and can only let it exist. What's even more interesting for Zhang Xiao is that every time the value on the wild boar is improved, his strength seems to become more abundant.

It's as if it's really as the Nirvana Emperor said, he lent his power to himself.

"Don't bluff there, no matter what the use of this wild boar is, Lao Tzu's next attack will definitely be able to kill you!"

After Zhang Xiao finished speaking, his arms gathered strength at the same time, and began to undergo strange changes, a little like he was constantly twitching, and a little like he had been drilled into an insect, shaking uneasily.

Immediately afterwards, Zhang Xiao suddenly exerted force under his feet, and the whole person flew into the air, aiming at the Nirvana Emperor in the air.

The Nirvana Emperor was not in a hurry, and before dodging Zhang Xiao's attack, he attacked again.

"Dark thunder."

The black lightning smashed into Zhang Xiao, Zhang Xiao blocked it casually, and the lightning still did not cause any damage, but the wild boar next to Zhang Xiao swelled again, this time becoming taller than Zhang Xiao, and at the same time issued a warning again:

"Under attack, the interest was recalculated, and the total principal and interest were raised to 6,650 pounds."

"Cut, die!"

Zhang Xiao had already rushed to the front of the Nirvana Demon Emperor, and suddenly launched an attack, his arms turned into chaotic flesh masses at the same time, and the blood, muscles and protruding bones were intertwined and crisscrossed, like a huge flesh and blood vortex, and the Nirvana Demon Emperor was enveloped in it in an instant.

"Demon Hide!"

The Demon Emperor turned into a ghost fire and disappeared again.

But this time, as soon as he reappeared in another position, Zhang Xiao's attacks followed, and one of the muscles had already tied up the Nirvana Demon Emperor, and the Nirvana Demon Emperor ignited the ghost fire in that position in time before destroying the muscles and escaping again.

The Nirvana Demon Emperor kept fleeing, and while using the Demon Concealment to escape, he also used the Dark Thunder to constantly attack Zhang Xiao.

Zhang Xiao's speed became faster and faster, glaring at the Nirvana Emperor viciously, and roared:

"You're running? Running as much as you want? Do you think you'll be able to beat me like that? Thank you for lending me this power, stupid garbage, your power will be exhausted sooner or later, and these lightning bolts you release are not as good as when a fly touches me, hahahaha...... But don't say anything, I really feel very comfortable after these attacks of yours hit me! ”

The Nirvana Emperor ignored Zhang Xiao's provocation, and still kept flickering, dodging Zhang Xiao's attack, and at the same time he did not stop fighting back.

Although neither side seemed to have suffered any damage, the speed of the Nervana Emperor had slowed down significantly, and it seemed that his own strength had been greatly consumed. On the other hand, every time the Nirvana Demon Emperor attacked, the wild boar that followed Zhang Xiao like a shadow would increase his value, and every ten seconds or so, it would increase again.

The boar phantom soon became more than five meters tall, and at the same time it sounded again:

"When the time for calculating interest is up, the total amount of principal and interest has increased to 28,567 pounds, and it has reached the peak of the power that the target can bear, do you want to launch the debt collector mode?"

Zhang Xiao didn't care about the change in what the wild boar said, and still attacked frantically, in his opinion, the Nirvana Emperor was already at the end of the crossbow, while constantly fleeing, and at the same time flying a kite to attack himself. This kind of boot-tickling attack couldn't hurt him at all, but the Nirvana Demon Emperor himself was already about to reach his limit, and his speed was getting slower and slower.

"Hahahaha...... See the gap, I've just finished warming up, but look at you, you're almost running out of strength to escape, right? Little trash! Zhang Xiao said excitedly, and at the same time accelerated the speed of the attack.

The two chaotic flesh giant arms were like the stirring sticks of a blender, dancing wildly in the Netherworld Void, covering almost the entire body of the Dome Bag, and the space that the Nirvana Demon Emperor could dodge suddenly became very limited, as long as he slowed down a little, he might be swallowed by this huge mass of flesh.

Sure enough, just as the wild boar phantom made a sound again, the Nervana Demon Emperor was suddenly trapped by two flesh and blood giant arms at the same time, firmly imprisoned in it, and the blood vessels penetrated deep into every crevice of the Nervana Emperor's body in a very delicate way, and those protruding chaotic bones also stuck his joints, such a way of imprisonment was even more difficult to break free from than being trapped in cement.

And the boar had turned crimson, its wings glowing with a treacherous light, and its voice had become very thick:

"When the time for calculating interest is up, the total amount of principal and interest has increased to 42,850 pounds, which has seriously exceeded the peak of the power that the target can bear, do you want to launch the debt collector mode?"

"Hahahaha...... I know you can't escape, how about it? Do you want to be pinched to death by me, or poked to death by bones? Little trash! Zhang Xiao pinched the Nirvana Emperor and shouted wildly.

Although the Nirvana Emperor looked very tired, his face was still indifferent, his eyes became more fierce, and he said in a deep voice:

"I originally wanted to take a good look at the picture of you kneeling down and begging for mercy, but now that it has gone so far, I'm afraid I shouldn't be able to see it."

It turned out that the evil technique used by the Nirvana Emperor, called "Hell Usury", was invented by Zen Master Otomi, one of the five great khenpos of the Ice Domain. After absorbing the power of the five Khenpos, the Nirvana Emperor himself learned their killer skills. "Hell Usury" is also one of them, the conditions for the activation of this evil art are more harsh, and it will not directly cause huge damage to the target in a short time, but its power is very terrifying, "Hell Usury" needs to meet two conditions before it can be activated, the first is that the chosen target must always be higher in strength than the user. Second, you have to touch the target's back to activate it. When the magic is successfully activated, it will summon the Hell Beast - Debt Collector Pig, and lend the target about 200 pounds of energy, and then each attack, will lend the target 200 pounds of energy, and the extra energy caused by the attack will be turned into interest and included in the principal and interest. In addition, every ten seconds, the debt collector pig will recalculate the principal and interest, and the interest is 0.5 times, that is, the principal and interest in the first ten seconds will directly rise to 1.5 times.

To put it simply, as long as you keep attacking the target, the target will exponentially increase the amount of borrowed energy. Even if the target is not attacked, the principal and interest that need to be repaid will continue to increase due to the passage of time, and during this period, the target will not suffer any substantial damage, and all damage from the outside world will also be offset by the protection of the debt collector pig.

However, when the value of the Debt Collector Pig adds up to more than the maximum force that the target can withstand, a warning will be issued, asking the user if they want to activate the Debt Collection Mode. If the user says no, the Debt Collector Pig will disappear, which means that the user has used this magic to protect the target, increasing its strength and protecting it from damage. However, in the same way, the power that the user has lent to the target cannot be restored by the effect of the hexical arts.

However, if the user initiates debt collection, then the debt collector pig will manifest and turn the total power of principal and interest into a substantial attack, recovering from the target, inflicting fatal damage on the target. At the same time, all the energy values will be converted into real energy and absorbed by the user.

At this time, the Nirvana Emperor looked at Zhang Xiao, showed a terrible smile, and said in a deep voice:

"Debt collection."

The Nirvana Demon Emperor gave an order, and at the same time exhausted the evil power in his body, the power exploded instantly, and the black ghost fire that rose around him suddenly devoured the flesh and blood that Zhang Xiao used to trap him, turning them into black smoke and devouring them all, and he also turned into ghost fire and fled to the top of Zhang Xiao's head.

The debt collector pig flew to the top of Zhang Xiao's head, Zhang Xiao's eyes widened, and he felt the signs of death for the first time, and he couldn't even speak.

The terrifying beast had turned fiery red, as if it had just been reborn from hell, and it aimed its sharp fangs at Zhang Xiao below, and the rolling waves of air sent the entire space vibrating.

"Debt collection begins!"

The Debt Collector Pig roared and slammed down.

Zhang Xiao heard this terrible sound in a trance, and ran wildly almost reflexively, in his impression, although the fierce beast that followed him closely looked fierce and vicious, it had not been able to cause any substantial damage to himself. But when it roared and rushed towards him, Zhang Xiao still chose to run away as soon as possible, and this reaction was completely instinctive.

However, even if Zhang Xiao strengthened his legs, he still couldn't get rid of the amazing speed of the debt collection demon pig, and the huge shadow finally completely enveloped Zhang Xiao, and in the space close to the vacuum, a roar broke out in an instant, and the surging energy flow formed countless waves that continued to spread, although the Nirvana Demon Emperor created a magic crystal shield in time to block it in front of him, the whole person was still shocked and fell back dozens of meters.

Zhang Xiao was crushed by the huge energy in an instant, and only a few relatively solid bones remained, which had already melted into the flesh and blood.

When the arrogance gradually subsided, the fluctuations in the void gradually dissipated, and a flickering light suddenly rose and merged into the body of the Nirvana Emperor, and the tired body of the Nirvana Emperor was immediately rejuvenated, and the ghost fire burned vigorously outside his body.

Zhang Xiao, who was invincible just now, turned into a pitiful fragment almost instantly.

The Demon Emperor shook his neck, looked up at the corpse bag, and said evilly:

"How? Can you give your answer now? ”
