Cao Yunfei has always been polite in front of her, and she has never seen such a murderous side of it.

She thought silently, her expression was also a little trance, and she suddenly felt a chill towards Cao Yunfei.

"Yu'er, do you feel a little disappointed in Cao Yunfei? He was already famous in the Tianyuan Kingdom, but it was only after he became your retinue that he deliberately restrained his murderous nature. Nangong Tian seemed to see through his daughter's thoughts, and suddenly smiled slightly.

Princess Nangong nodded slightly and did not speak.

"Yu'er, if you could choose Cao Feihu and Zhao Yu, who would you choose? Cao Yunfei has Cao Feihu behind him, and although Zhao Yu can cast the Death Immortal Technique, I can already see that he is the same as the rumored peerless powerhouse。。。。。。 After a moment, Nangong Tian asked again.

"Father, I don't know. When Princess Nangong heard this, she immediately pondered for a long time, and then smiled and said.

"Hahaha! If they can fight each other in the proving ground, maybe only one of them will survive, and then you won't have to choose. Nangong Tian suddenly laughed.

。。。。。。

A few days later, Zhao Yu met a terrifying and mysterious powerhouse. He can transform into a cloud of shadows, blending with the surrounding vegetation, mountains and rocks, and it is extremely difficult to detect. Even after urging the Trial Token with all its might, it was impossible to detect a trace of it.

When he noticed that the mysterious powerhouse seemed to be extremely familiar with the Trial Token, he no longer relied on the exploration of the Trial Token, but secretly cast the Void Realm.

Suddenly, Zhao Yu noticed that the surrounding scene seemed to have undergone a slight change, and all the plants and trees became very strange, as if they were alive.

But Zhao Yu didn't have a sense of comfort, he was faintly aware that an invisible danger was quietly approaching him, and he might launch a ferocious attack on him at any time.

Whoa!

Suddenly, all the surrounding plants and trees turned into immortal soldiers, flying towards Zhao Yu from all directions.

Their might was terrifying, causing the void to tremble violently.

But Zhao Yu's imaginary artistic conception quickly saw through them, and everything was an illusion.

Those plants and trees were cast by the mysterious old man with some kind of strange immortal tricks, which is why they are so weird.

Rumble!

Suddenly, one of the small trees transformed into a mysterious old man, and he bombarded Zhao Yu with a palm.

That palm was very terrifying, and wherever the palm wind went, it was like a vast torrent, and they were condensed by surging immortal energy, and they slammed towards Zhao Yu.

Zhao Yu immediately urged a chaotic immortal power in his body with all his might, and in an instant, the immortal power in his body skyrocketed, as terrifying as a half-immortal king realm powerhouse.

That terrifying palm wind was immediately destroyed by the immortal power gushing out of Zhao Yu's body.

In an instant, the immortal power gushing out of Zhao Yu's body swept around, and almost all the illusions disappeared at the same time.

Shout!

The mysterious old man immediately turned into a streamer of light and fled into the distance, he didn't want the immortal power gushing out of Zhao Yu's body to spread.

Thundered!

Within a radius of 100 miles, it was as if swept away by a terrifying tornado, the grass and trees turned into flying ash, and the mountains turned into powder.

"Boy, what kind of immortal trick have you cultivated, and you are so powerful?" the mysterious old man said after flying hundreds of miles.

"Who are you, why did you attack me?" Zhao Yu said coldly.

"This is the Heavenly Abyss Proving Ground, there are bloody slaughters everywhere, I was originally a prisoner, so I naturally wanted to kill you and seize a trial token. The mysterious old man quickly spoke.

"It's a pity you can't kill me!" Zhao Yu's face was gloomy, and he said again.

"Boy, you are very powerful, why don't we join forces, I will give you a great benefit. The mysterious old man spoke again.

"Old man, you are even more powerful, even the trial token can't detect your traces, I don't dare to join forces with you. Zhao Yu pondered for a moment, and then said.

At this time, Zhao Yu's heart was in a trance, and in an instant, many familiar faces appeared around him.

But all of a sudden, they all came towards Zhao Yu with gloomy faces, and they all exuded terrifying immortal power fluctuations, and their strength seemed to have skyrocketed many times.

"Illusory Immortal Formula!" Zhao Yu suddenly came to his senses, and his heart was shocked.

Rumble!

Zhao Yu immediately urged the immortal power in his body, and in an instant, a terrifying force swept around, destroying all those figures.

In an instant, all the illusions disappeared, and he was fully awake.

"Boy, you can even break my illusory immortal formula, it seems that I must cooperate with you this time!" the mysterious old man looked shocked and said immediately.

"Old man, you are so hateful, I will kill you. Zhao Yu looked angry and roared.

"Boy, don't be angry, have you heard of the Chaos Immortal Source?" the mysterious old man hurriedly said.

"Chaos Immortal Origin, that's a legendary strange thing. Zhao Yu pondered for a long time, and then said.

"Boy, I know there is a place where there is a Chaos Immortal Source, and if you can join forces with me, you may be able to find it. The mysterious old man spoke again.

The mysterious old man communicated with Zhao Yu for a long time through divine consciousness transmission, and finally Zhao Yu decided to take the risk and join forces with him.

Immediately, Zhao Yu followed the old man into a mysterious valley, where a cloud of immortal mist was shrouded, and outsiders could not use the trial token to probe the slightest bit inside.

"Old man, you seem to be very familiar with this place?" Zhao Yu suddenly asked.

"Yes, I'm very familiar with this place, and I've been able to survive several trial battles in the Abyss Proving Ground, all of which depend on this place. The old man smiled slightly and said.

Although Zhao Yu's face was very calm, he was still secretly wary of him.

"Boy, I gave you this strange stone, and you can isolate the detection of the trial token with you. The old man seemed to sense that Zhao Yu was wary of him, so he took out a strange piece of jade and said.

The piece of jade was the size of a child's palm, and there were natural runes on the surface, like natural fairy runes, and it exuded a wonderful light.

Zhao Yu pondered for a moment, then took the jade, and then urged the trial token with all his strength to test it, and found that it could indeed isolate the detection of the trial token.

"Boy, don't worry. Now that you and I have become allies, I will never assassinate you. The old man suddenly grinned and said.

Zhao Yu glanced at the old man and nodded slightly.

"Senior, where did you get this piece of jade?" Zhao Yu asked after a moment.

After getting the jade, Zhao Yu was much more polite to the old man, calling him an old man before, but now calling him a senior.

"Boy, you are a big secret, I can't tell you for the time being, but there are several pieces of such jade, in addition to the two I got it, there are several people who have one each. However, this secret must be strictly guarded by everyone, and even the king of the Heavenly Abyss Kingdom does not know about it. The old man pondered for a moment and said slowly.
