As soon as he returned home, Zhao Yao sat cross-legged and sat on his bed thinking about the upgrade.

For the next upgrade strategy, Zhao Yao has already considered it many times.

First of all, compared to upgrading matcha, Elizabeth, briquettes or Ares, Zhao Yao is more inclined to upgrade BOOK.

After all, he didn't know what new features would be added to the next layer of the super cats' skill tree, but he signed up with the super cats, and he knew what new abilities he would get.

So Zhao Yao thought about it a little and chose to upgrade the BOOK.

So Zhao Yao directly chose to upgrade, and the next moment he felt a strong force falling from the top of his head, all the way to the foot force, every bone, every muscle seemed to melt under the urging of this force.

At this moment, Zhao Yao felt soreness, pain, and heat all over his body, as if every nerve had been ravaged.

He was sweating and lying on the bed, and it took five minutes for the whole person to slowly recover.

At this time, Zhao Yao had already fused the power of Ares and reached the power of the four cats.

He exhaled deeply, and the first thing he felt different was his own perception.

With a flick of his eyes, he could see the dust in the corners of the room in the dim light.

With a slight twitch of his ears, he could perceive the presence of all life in his home.

With a sniff of his nose, he could smell all kinds of people, cats, and garbage in the air.

Zhao Yao suddenly pulled open the mattress and smiled slightly at the pack of catnip hidden under the mattress.

"Hehe, are the briquettes hidden? Think the most dangerous place is the safest place?"

Zhao Yao's five senses and insight at this moment almost reached an inhuman realm, and he could feel that even if he closed his eyes, his perception of the room did not seem to have much impact.

He even felt that his mind was clearer than ever, and it seemed that there was an indescribable spiritual sense.

"Cat's intuition?" Zhao Yao shook his head with a smile, waved his arm, and felt an indescribable ease all over his body, as if he had unloaded a burden of dozens of kilograms.

"The physical fitness of the four cats has been added. Zhao Yao jumped on the spot, turned his head directly on the spot, and then walked upside down with a slight force with both hands, still flexible like an ordinary walking human.

He felt that his strength, speed, and explosiveness had increased by several points, and his physical fitness was almost the same as that of top athletes, and his agility, agility, reflexes, and flexibility were far beyond the limits of human beings.

"Hehe, if I go to the Olympics now, I'm afraid I will win gold medals in gymnastics, track and field, and swimming casually. ”

After upgrading the BOOK, you can sign a super cat to complete the main quest.

However, Zhao Yao was a little hesitant about which super cat to sign.

In fact, Zhao Yao's first target was naturally the Pharaoh Cat.

Pharaoh's exercise ability is to improve physical fitness in an all-round way, and even because the essence of ability is exercise, even if the ability is switched, it will not affect the physical fitness that has been obtained through exercise.

Having this ability is equivalent to permanently solidifying a superpower of physical fitness, and when Zhao Yao switches other abilities, it is equivalent to always having two abilities.

However, although Pharaoh's ability is good, there is a huge problem, that is, his hostility towards Zhao Yao is still too deep, and if he signs a contract now, it is likely that his loyalty is extremely low, resulting in the inability to activate his ability even if he signs a contract.

In this case, it is equivalent to wasting a signing slot.

So Zhao Yao has a second choice, that is, to sign Lucifer and obtain the ability to regenerate super quickly.

For this god-level life-saving ability, Zhao Yao has been coveting it for a long time.

He Haocang, who has obtained the ability of ultra-rapid regeneration, can survive even a zero-distance explosion, once Zhao Yao obtains this ability, it is almost equivalent to getting half an immortal body, it is estimated that as long as it is not a situation of being wiped out and buried in the deep sea, he will not be able to die.

Although matcha's distortion in time and space has the effect of rebirth, it can only be used once a day.

If you are injured in battle, such as a broken hand or foot, or a broken tendon, then it is not used or not.

At this time, ultra-rapid regeneration is a very good choice, which can allow Zhao Yao to quickly recover from various injuries.

"Ultra-fast regeneration combined with space-time distortion can also switch between the self-devouring of briquettes and the repulsion field protection of Ares. Zhao Yao felt excited just thinking about it, after having super fast regeneration, his survivability had risen several levels.

What's more, you can still use BOOK to upgrade your ability when the time comes, and now the super-fast regeneration is already so terrifying, I don't know how powerful it will be after upgrading.

Thinking of this, his eyes suddenly flashed: "By the way, although I can't use the Pharaoh Cat's ability, I can let the Pharaoh Cat lend the ability to Bai Quan." ”

Zhao Yao had already tried it when he caught Yuanyuan, he didn't know if it was because of the BOOK relationship, or because he wasn't an apostle in the first place, anyway, he couldn't borrow the power of the super cat like the apostle.

But he's not an apostle, his younger brother is.

"Hey, hey. As long as Bai Quan borrows the ability of the pharaoh cat to exercise every day, he will be a pharaoh cat again in a few months. When the time comes, stealth and a physical quality like the Pharaoh's cat, isn't it a fighter among assassins?

As soon as he thought of this, Zhao Yao became excited.

Although he usually asks Yuanyuan to lend his stealth ability to Bai Quan every day, the simple stealth ability is still very powerful, but once it is discovered, it is likely to be a heavy hit.

Therefore, Zhao Yao only let Bai Quan get used to using his abilities, and never intended to let him take the initiative to fight.

But now, if the stealth is combined with the super physical fitness of the Pharaoh Cat Duan, it will be terrifying just thinking about it.

"Hehe, it's not just Bai Quan, pull Zhao Xue up. Just send the two of them directly when you see the enemy, and I can hide next to me and output. ”

As soon as he thought of two men and women who could knock down a wall with one punch, and they were still walking silently and difficult to distinguish with the naked eye, Zhao Yao couldn't help but mourn in silence for his opponent.

Zhao Yao thought in his heart: "Well, even if they are injured, I can spit out Lucifer anytime and anywhere and borrow their abilities to heal them, no, as long as they are willing, I can directly let them into the dimensional stomach bag, and then let Lucifer heal their injuries."

Well, or super fast regeneration with super physical fitness, this berserker combo is also great. ”

"But if I sign Lucifer, I need to control my loyalty, after all, I can't lend my power to others when I reach 100 loyalty points. ”

However, in Zhao Yao's opinion, this is a trivial matter, after all, it is not easy to reduce loyalty.

"Well, no matter which one you sign, you can lend the Pharaoh Cat's abilities to Bai Quan and Zhao Xue, but which one to sign will have to be discussed with the Pharaoh Cat. ”

"Well, let's let him lend his ability to Bai Quan first, and test this guy's attitude. ”

Thinking of this, Zhao Yao walked out of the door to find Bai Quan.
