When the old man said this, Su Yun understood a lot of things, such as why he was able to complete the Legend of the Four Rings task in the first world, it was because he didn't have any 'cause and effect' in his body, and the plane consciousness was not so sensitive to him, so he could complete the Four Rings task under the nose of the plane consciousness.

On the other hand, Yu Xiao has already reached the peak of the second order, and he doesn't know how many worlds he has experienced, and he should have much more 'cause and effect' than Su Yun, so the old man said that accumulation is worthless.

"To measure which of the two of you is more suitable to be an executor, it is natural to look at your strength and the ratio of cause and effect, the higher the ratio, the more suitable you are to be an executor, do you understand what I mean?" The old man said what he meant in the end.

Yu Xiao chuckled, glanced at Su Yun, and said disdainfully: "What a coincidence, I have only had a total of fifteen worlds from the first world of the first order to now!" If you want to compare strength to karma, hmph, I'm afraid it's impossible for me to lose. ”

Of course he has this self-confidence, fifteen worlds have rushed to the peak of the second order, which is already considered a god speed among ordinary people, he has relied on high-level assistance along the way, as well as Meka's personal gifts, and his strength has been rising like a rocket, which is also the fundamental reason why he is willing to help Meka do so many dirty things.

On the other hand, Su Yun, as a hunter, has never received high-level assistance, and relies on one person to work hard, and he is definitely not comparable to him in terms of strength and the ratio of cause and effect.

Yu Xiao stood up confidently and said: "Since this is the case, it is better to compare strength and cause and effect, and whoever is higher will be the executor." ”

The old man's eyes lit up slightly, looked at Yu Xiao, and said, "Are you sure?" The choice is yours. ”

"Of course."

The old man nodded, and then said to the two of them: "Your causal ratio is about one to three, so I plan to take this way: you fight in the illusion I built, in which the weaker side can get three chances to resurrect in place. ”

"What? One to three?! Yu Xiao's face was full of disbelief, he stretched out his somewhat rough fingers, and pointed at Su Yun with a slight tremble: "This, has this guy only experienced five worlds?" ”

Su Yun said lightly: "That's right, this is the sixth plot world I have experienced, if you don't count the judgment war that the ghost king did his hands and feet." ”

Su Yun said as he realized one point, that is, the trial war itself did not bring him the burden of cause and effect, but when calculating the qualifications for the final battle, it was calculated

The boss's eyes narrowed slightly.

He suddenly realized a fact.

This time the battle must be won!

If this Su Yun is allowed to live, then if five more worlds pass, the strength of this guy on the other side will not be able to be contained!

We must get rid of him before he grows up!

The boss was very confident in his own strength, and in his conception, Su Yun must have encountered some ordinary opponents in the "Local Illusion Realm".

Naturally, he didn't take a master like Wu Lie into account, because the Ghost King hired Wu Lie to hunt down Su Yun with a lot of money, and he didn't tell Yu Xiao about it at all. Even if he said it, Yu Xiao would not believe that Wu Lie would die at the hands of Su Yun.

"I agree" Su Yun certainly had no reason to refuse.

"I agree too! But I need space to witness, no one is allowed to interfere in our battles in the middle of the battle, and I need a completely fair battlefield! Yu Xiao took out a dueling scroll and said, "I hope to use this to ensure the fairness of our battle." ”

Duel scrolls are space-released scrolls that guarantee that two people can fight fairly on a certain condition.

The silver-haired old man nodded and said, "No problem, I will definitely act fairly in this battle." ”

Yu Xiao opened the duel scroll, and two rays of light fell on Su Yun and Yu Xiao respectively.

"Ding, the contractor 15556 used the duel scroll on you, do you confirm the signing of the duel contract, this contract is a completely fair contract, to ensure that others will not interfere in the middle of the battle."

Su Yun checked the scroll, and after making sure that there was no problem, he clicked OK.

He didn't think that Yu Xiao would do anything about this kind of contract, if he dared to do it, then the judgment thunder above the world would give him a taste of what is called real harm!

The Judgment Thunder is not only effective for the people of the Troubled Country, but also for anyone who tries to break the rules by any means!

When Yu Xiao saw Su Yun accept the contract, he immediately looked at him as if he was looking at a dead man.

The old man's quill shook slightly in the air a few times, and then a halo spread out from the barrel of his pen, and Su Yun and Yu Xiao's eyes lit up, and they appeared on a flat ground.

It's a very simple scene, with an ordinary gray ground, a normal blue sky, no clouds, no sun, no obstacles around, no borders, no wind, normal gravity, nothing superfluous.

Yu Xiao looked at Su Yun who was standing not far away, and the corners of his mouth hooked up a cruel smile.

Su Yun just looked at the enemy in the distance lightly and was unmoved.

Yu Xiao attacked first, and a red flying dragon rolled up on the spear in his hand, and shot down at Su Yun.

Su Yun calmly stretched out his finger towards Yu Xiao, and a blue light fell on Yu Xiao's body.

"Ding, you stole 20% of the agility attribute of the target panel, and you stole 44 agility attributes."

Su Yun instantly deduced that Yu Xiao's agility attribute had reached a high of 220 points!

However, this value, in front of Su Yun today, has no effect at all!

Yu Xiao recovered from the exile and continued to charge towards Su Yun, they didn't even know that they had been banished.

The spear stabbed at Su Yun like a swimming dragon, but Su Yun easily dodged it, Yu Xiao was shocked in his heart, only to find that his agility had been deducted by as much as 44 points in vain, and he now only had 176 points of agility left!

And Su Yun dodged his attacks with ease, and seemed to be more agile than himself!

He had seen the holographic video of Su Yun killing the Dark Gemini Star and the Three Phantom Gods in seconds before, and he suddenly had a hint of realization in his heart, it seemed that this Su Yun had explosive and agile means, and he could instantly increase his speed to the level of the fourth order!

He didn't expect that Su Yun had stacked his attributes to the current level with the Star Spell Banishment, and at this moment, his panel agility had reached a terrifying value of 194 points!

This is still the dark shadow that he has not opened the palace guarding ring, and he is already more than a dozen points more agile than Yu Xiao, an agile contractor!

Su Yun grabbed the barrel of the spear, picked up the pan with his right hand and knocked on the door of Yu Xiao's head.

Of course, Yu Xiao would not let Su Yun hit him, the soles of his feet slipped for a while, and he dodged from Su Yun's blow, and the spear in his hand was flexibly rolled up, and he broke free from Su Yun's hand.

In the first encounter, Yu Xiao had a slight disadvantage.

Of course, there must be more than that.

Yu Xiao jumped a few times and distanced himself from Su Yun, and fine scales appeared on the surface of his body, a pair of blood-colored fleshy wings spread out behind his back, and a scarlet tail grew out behind him!

There was an aura of calamity around him, as if he were a demon from hell.

This should be Yu Xiao's bloodline transformation skill, Su Yun thought to himself.

However, the next moment, something happened that made his brow furrow.

Yu Xiao's figure in mid-air suddenly blurred, and then thirteen Yu Xiao suddenly appeared in mid-air at the same time!

The art of clone!

This is exactly one of Su Yun's most headache skills, his star spell banishment and the desolation of the world are all aimed at monomers, and the last thing he is good at is fighting with a bunch of people.

Thirteen Yu Xiao waved their wings at the same time, and flew towards Su Yun at a rapid pace, Su Yun had to spread the light wings of the rune battle armor, and also flew up, dodging the pursuit of the thirteen Yu Xiao!

This boss who can catch and win from the thirty-one pursuers really still has something.

After Yu Xiao's transformation, it seems that his agility has also improved a lot, a little higher than Su Yun, Su Yun had to open the dark shadow of the palace guarding ring, adding an additional 20 points of agility, and distancing himself from Yu Xiao.

He doesn't know which doppelganger is real, so there is no way to use the light of the broken soul, if he wants to use the immortal power of time, and he doesn't know which doppelganger is the right thing to apply to the time lag, if he only turns on the speed of time, to open the equivalent speed gap, the consumption is a little too great.

He still has three chances to resurrect in situ and full state, and it's not worth using all the immortal power now.

As everyone knows, Yu Xiao's heart is also extremely depressed, he didn't expect Su Yun to have such a high movement speed, and the duration of his transformation and clone is limited, if he can't kill Su Yun in the state of transformation, I'm afraid that he will be crushed by Su Yun with speed later.
