Lu Yao leaned out his sense to examine the killer whale and found that it was seriously injured and unconscious. If you don't save it, it's likely to die.

And once you choose to take action, you may delay the time to rescue your brother-in-law, because the killer whale is so seriously injured, it is unrealistic to rescue in the East China Sea, the natural conditions here are too bad, at least you have to move to the sea of Fanghu Xiandao.

Thinking about it, Lu Yao still couldn't bear to see the killer whale die like this, not to mention that he didn't have the specific whereabouts of his brother-in-law for a while, even if he wanted to search, it would take a while, it would be better to wait to save the killer whale, whether he could let it help search and rescue together, maybe it could be faster.

Thinking of this, Lu Yao manipulated the Xuanyuan Water Control Flag to roll up the fishing boats and killer whales, and transferred from the East China Sea to Fanghu Immortal Island.

As soon as he landed on the sea surface of Fanghu Immortal Island, Lu Yao suddenly felt that his head was splitting, and his head was about to explode, as if there was a red-hot iron rod constantly stirring in his brain, and he wanted to die in pain.

Lu Yao knew that he was careless this time, his mental power was overspent, and he used the Xuanyuan Water Control Flag several times to suppress the wind and waves along the way, but he didn't know whether he was alive or dead this time, and at the same time communicated with a big ship of more than 30 meters, and also attached a killer whale three or four meters long, what is this not looking for death?

But fortunately, at this critical moment, the automatic head of the Xuanyuan Water Control Banner continued to extract the aura on the sea surface of Fanghu Immortal Island and converge towards Lu Yao.

Even the Xuanyuan Water Control Banner also communicated with the island protection array, extracting spiritual energy from the open sea to make up for the huge consumption of spiritual energy in the inland sea.

At a certain moment, the island protection array, which had been running for an unknown number of years, paused inexplicably for a moment, and a wisp of ancient and barbaric breath slipped into the inland sea of Fanghu Immortal Island without knowing how many years it had been running, and swooped down on the dying killer whale.

As that wisp of ancient and barbaric aura entered the killer whale's body, the killer whale actually began to unconsciously absorb the incomparably rich aura from Lu Yao's side, quickly recovering from the internal injuries in the body.

The Xuanyuan Water Control Flag seemed to sense that the killer whale was absorbing the aura, and the flag that had previously covered Lu Yao's body instantly expanded, enveloping the killer whale in the encirclement.

Immediately afterwards, a wisp of innate Hongmeng purple qi that could not be checked seeped out from inside the Xuanyuan Water Control Flag, continuously nourishing the bodies of Lu Yao and the killer whale.

As the wisp of innate Hongmeng purple qi was inhaled from Lu Yao's nose, it was spit out by Lu Yao after running according to the Xuanyuan Water Control Technique for a long time, and soon entered the killer whale's body, and the wisp of innate Hongmeng purple Qi actually swam around the killer whale's body according to the Xuanyuan Water Control Technique's practice route, and finally returned to the Xuanyuan Water Control Flag.

Unconsciously, Lu Yao didn't notice that the killer whale's body faintly exuded a trace of his own similar aura.

Lu Yao seemed to feel that he had turned into a silkworm cocoon, surrounded by a thick aura shield woven by the aura, and he was like a person who had been thirsty for three days without water to drink, greedily absorbing the aura in the aura cocoon.

I don't know how long it took, Lu Yao heard a crisp "click" sound in his body, and something in his body seemed to break that had been bothering him, and the aura surged into his whole body at a faster speed.

"Bang!"

The aura cocoon cracked, and Lu Yao, who had been in a coma because of the pain, woke up, he twisted his neck and arms slightly, and found that his head didn't hurt at all, just like a person who woke up from a beautiful sleep, eliminating fatigue and recovering all his energy.

Lu Yao turned his head and saw that the killer whales on the deck of the fishing boat were breathing gently, and they seemed to have come back to life from the brink of death.

He poked out his divine sense and wanted to sense the current state of the killer whale, but suddenly found one thing, his divine consciousness that could only cover a range of thirty meters had actually doubled, reaching a range of sixty meters.

"Have you stepped into the fourth layer of Qi cultivation and entered the middle stage of Qi training?"

Lu Yao used his divine sense to look inside his body, and found that unconsciously, he had broken through from the third layer of qi training to the fourth layer of qi training because of misfortune, and he couldn't help but be overjoyed.

Don't look at the difference between the third layer of Qi training and the fourth layer of Qi training, in fact, it has already crossed a small realm, and there is a huge difference in the strength of the two.

If the third layer of Qi training can only use some simple auxiliary spells, then the fourth layer of Qi training can already start using most of the attack spells, and it can be said that it has increased more than ten times in terms of combat effectiveness.

And his mental power has also doubled, and it will be more handy to use the Xuanyuan Water Control Flag again, even if he is teleporting such a large fishing boat and killer whale today, at most his head will twitch for a while, and there will be no headache and coma.

Just when Lu Yao was happy about his promotion, a voice of "um~uh~" came from the side, which made Lu Yao come back to his senses.

Lu Yao glanced sideways, and it was the call of the killer whale beside him.

This didn't matter, but it made Lu Yao show a look of surprise, and he hurriedly used his divine sense to sense it, and finally confirmed that his guess was correct, this killer whale didn't know what great opportunity it get, and evolved into a low-level demon beast, although it is still the lowest-level first-order demon beast, but as long as he continues to work hard to cultivate, he may not be able to evolve into a high-level demon beast in the future.

In fact, what Lu Yao didn't know was that this killer whale could evolve into a demon beast, which had a lot to do with him.

First of all, the Xuanyuan Water Control Flag extracted the aura of the sea outside Fanghu Immortal Island, so that the island protection array stopped running for a short moment, and a wisp of ancient barbarian breath in the open sea was able to possess the killer whale, but if it was just like this, at most, it would allow the killer whale to recover from internal injuries in the body, and it might not be able to evolve into a demon beast, after all, that breath was too weak, otherwise it would not be able to escape the blockade of the island protection array.

But then the wisp of Xuanyuan Water Flag innate Hongmeng purple qi entered Lu Yao's body, and when he repaired his injuries, he took out all the dragon ball qi that had not been completely digested in Lu Yao's body and entered the killer whale's body, which was the key factor that prompted the killer whale to evolve from an ordinary beast to a demon beast.

The ancient barbaric aura plus the innate Hongmeng purple qi and the dragon ball qi, coupled with the huge aura here, provide a guarantee for its evolution, if one of these four is missing, the killer whale will not be able to evolve into a demon beast.

Lu Yao sensed the faint but incomparably pure demonic aura in the killer whale's body, and he suddenly smiled: "I didn't expect that you, a big guy, would have such an opportunity, no matter what, I will help you again, and it will be up to you to achieve it in the future." ”

Although the killer whale has evolved into a demon beast, if it doesn't know how to cultivate, it still can't continue to advance, and can only stay in the first-order demon beast realm. Maybe it can evolve slowly over time, but that speed is too slow, and there has to be an environment suitable for it to evolve.

Obviously, although the Inland Sea of Fanghu Immortal Island was full of spiritual energy, it was impossible for Lu Yao to keep it here, because there was not enough food for it to eat.

If it returns to the East China Sea, with the thin aura of the earth, it is unknown whether it will be able to continue to evolve.
