"No, I'm asking you to watch for me, and if you find out I'm going to fall asleep, stab me with a knife, but this time, I think I should be able to hold on." Xu Lin looked at Chu Jun with some concern, "Remember, I can't support it anymore and stab me again, and don't prick my ass." ”

Even if the prince is really "big-chested and brainless", he knows that this kind of thing must not be sloppy, not to mention that the prince himself is not only not stupid, maybe he is also a genius of cultivation, at this time, the prince also put away his playful expression and listened carefully to Xu Lin's advice.

"Brother Xu Lin, will you hurt yourself or Xiao Hei by doing this ritual?" The prince asked with concern. She always thought that Xu Lin's promotion of Xiao Hei was similar to some kind of sacrificial ritual.

Regarding this point, Xu Lin didn't know how to explain it in detail, so he could only wait for the right time in the future, and Xu Lin would tell the prince.

"I'm not in danger of my own life, but if I can't succeed, Xiao Hei will be in danger." Xu Lin looked at Xiao Hei on the side, he couldn't let Xiao Hei have an accident, "Xiao Hei, don't worry, I'm very confident this time, and I have Agarwood and Chujun to protect it, double insurance." ”

Xiao Hei sat obediently in front of Xu Lin, no matter what decision he made to Xu Lin, it would not object.

Chu Jun touched Xiao Hei's head, "Brother Xu Lin, for Xiao Hei's sake, you must succeed." ”

Xu Lin nodded, he must succeed.

Xu Lin opened the small wooden box of agarwood and put it beside him, after learning the spiritual power combat method, he adopted the five-hearted cross-sitting posture this time, sitting cross-legged opposite Xiao Hei.

"Xiao Hei, Prince, I'll start."

The prince nodded heavily, staring at Xu Lin intently.

Summoning the mark of the Ten Thousand Worlds Summoner in his mind, Xu Lin quickly opened the upgrade ball and gave the order to "upgrade Xiao Hei".

The feeling of exhaustion instantly rushed to his brain, and Xu Lin's consciousness was fully prepared, and when he was about to accept the baptism of the storm, he found that the feeling of exhaustion did not seem to be as strong as expected, and it was not even as obvious as the feeling when he first created Xiao Hei.

A burst of refreshing light fragrance came, which was the smell of agarwood.

Xu Lin felt a clear mind in his mind, as if he was in the whole agarwood forest, the air here was fresh, there was no stench on the zombies that could be smelled everywhere, the environment here was beautiful and full of life, and there was no dilapidated depression everywhere in reality.

Xu Lin frowned slightly, how could this upgrade be so easy. Could it be that his mental strength has far exceeded four times that of the past?

However, as the fatigue continued to accumulate, Xu Lin's peaceful state of mind gradually became less relaxed.

Half an hour later, a drop of sweat oozed from Xu Lin's forehead, and the prince looked at Xu Lin without any change, at most, he frowned occasionally, and remained motionless most of the time, which made her a little depressed, and couldn't help but suspect that Xu Lin would not fall asleep while sitting.

Nearly an hour later, Xu Lin opened his eyes.

"This upgrade turned out to be much easier than I expected." Xu Lin sighed with emotion, it seems that his spiritual power should be more than four times that of the original.

"Brother Xu Lin, you can be regarded as awake, you haven't moved, I'm about to stab you down." When Chu Jun saw Xu Lin wake up, he finally breathed a sigh of relief.

"Prince, it's hard work, you rest first." Xu Lin didn't stand up, he looked at Xiao Hei in front of him, who was staring at him with round eyes. "Blackie, how do you feel?"

"Wow!"

"Strong again? I'll take a look at your attributes. Xu Lin immediately called up Xiao Hei's new data in his mind.

Under Black's image, two rows of data are displayed.

"Guardian of this Seal: Sky Shaker."

"The current rating, Labrador retriever dog three stars. Strength: 1.5, Speed: 1.5, Agility: 1, Recovery, 1, Defense, 1. ”

"Status, upgradable, requires 8 units of energy."

Xu Lin was the first to notice that in this upgrade, Xiao Hei had another attribute "Defense", and the value was also 1.

"Defense? This is Blackie's weakness. Xu Lin looked at the final result and was very excited, it was precisely because of Xiao Hei's physical fitness that Xu Lin had been worried that Xiao Hei would be injured when he fought with zombies, and now with this new attribute, Xiao Hei's strength has once again been qualitatively improved.

"The speed increases by 1 attribute, plus the defense of the new attribute is also 1, it seems that every time you upgrade, Xiao Hei's attribute points will increase by 2 points." Xu Lin had played a lot of games before, and he was still very sensitive to attributes. It quickly analyzed the pattern of each upgrade.

An upgrade increases 2 attributes, which doesn't seem like much, but when Xiao Hei's strength is 1, it's greater than that of zombies. It can be seen that this attribute has a very high gold content.

"Brother Xu Lin, has Xiao Hei become stronger? Why can't I see it? The prince squatted down and looked at Xiao Hei carefully. But it's really a little taller. ”

Xiao Hei was upgraded to one star, and when he was three stars, his body grew taller, and these two upgrades had one thing in common, his strength and speed were improved.

"Yes, it's strong." Xu Lin touched Xiao Hei's head vigorously.

"Oh, Xiao Hei, I won't be able to catch up with you when digging in the future." Chu Jun was also very happy when he heard Xu Lin say this. "By the way, Brother Xu Lin, why don't you look tired at all this time, it's completely different from last time. To be honest, I've been wondering if I'll be able to do it if you're still like last time. ”

Xu Lin and Chu Jun were not familiar with each other before, so when Chu Jun started, he was more worried, but now the two have also experienced a lot together, and it is really not easy for people to stab so many knives in their relatives.

"I can't do it, I just get hurt, but if I fail, Xiao Hei's life is in danger." Xu Lin looked at Chu Jun with a smile, "It's still early, why don't you help me again." ”

"One more time?" The nerves that the prince had just relaxed tightened again, "You won't still ......"

Xu Lin looked directly into Chu Jun's eyes and nodded.

When upgrading before, Xu Lin had already felt that he was fully capable of resisting the consumption of spiritual power by himself, and upgrading Xiao Hei again would cost twice the mental power, Xu Lin roughly estimated that he should be able to bear it, even if there was some danger in the end, there was also the prince as the final guarantee, it can be said that it is very safe to upgrade Xiao Hei again.

"I believe you Brother Xu Lin, I feel that I shouldn't need to pierce it, but just in case, you can help me watch it." Xu Lin slightly dispelled some of the prince's concerns.

The second upgrade soon began.

This time, Xu Lin obviously felt that the feeling of exhaustion was much stronger than before, and he took a deep breath of the air with the agarwood fragrance in his mouth, concentrating on fighting the fatigue.

An hour later, Xu Lin opened his eyes again, only this time, his expression was not so relaxed, and his body almost fell to the ground, but fortunately, Chu Jun's eyes were quick and he helped Xu Lin.

"Brother Xu Lin, it's okay."

Xu Lin struggled to sit up, "I'm fine." ”

Xiao Hei's eyes looked at Xu Lin intently, and his black tail swept around on the ground.

It seems that Xiao Hei is fine, Xu Lin can't wait to open Xiao Hei's attributes.

"Guardian of this Seal: Sky Shaker."

"The current level, the Labrador Retriever is four stars."

The upgrade was successful!

Xu Lin continued to look down.

"Strength: 2, Speed: 2, Agility: 2, Recovery, 1, Defense, 1."

"Status, upgradable, requires 16 units of energy."

"Awaken the talent skill, Claw Storm."

Awakened Talent Skill Talon Storm? Xu Lin's eyes widened.
