Sky Fox's fox eyes showed a hesitant look.

"I know that if I want you to surrender to Ling'er as her spiritual pet, you will feel that it is not worth it." Chi Yu smiled, "So it's better to protect Ling'er until she reaches the realm of a land immortal, find your physical body and help you restore to its original form, and then you will be free, how about it?" ”

Sky Fox narrowed the fox's eyes and glanced at Gu Linger, "Let her swear a blood oath." ”

Gu Linger was stunned when she heard this, looked at Chi Yu, saw Chi Yu nodded, and didn't think much about it, she raised her palm, swore to the sky with three fingers and a sword, "I, Gu Linger, swore a blood oath today, and ...... with me."

She didn't know what the name of the sky fox was, so she said here and glanced at the sky fox.

Tianhu said leisurely, "Tianling! ”

"After the Heavenly Fox Demon King Tianling made a contract, if he cultivates to reach the realm of a land immortal and helps it recover his physical body, I will immediately restore its freedom, if I violate this oath, I Gu Ling'er will definitely die with five thunderbolts that day!"

After taking the oath, Gu Linger felt that there seemed to be something more in her body and even in her soul, and she estimated that it was the blood oath she had made.

"It's your turn!" Chi Yu looked at the sky fox and said, "You must swear too!" ”

The eyes of the fox narrowed in danger, but he still swore a blood oath according to Chi Yu's request, "I swear by the Sky Fox Clan, and after the deity Fox King Tianling and this female Gu Linger make the oath of the lord's favor, no matter whether the body is restored or not, you must protect her to reach the realm of land immortals, otherwise she will die after the catastrophe and her soul will be destroyed!" ”

"Good!" Chi Yu said, "Then I'll help you make a contract now!" ”

As soon as the words fell, Chi Yu took out some magic weapons and array flags and set up a formation on the spot.

Gu Ling'er stood in the position of the master of the formation, and let the Heavenly Fox Demon King Tianling stand in the center of the formation.

Chi Yu said, "Now I'll read a sentence, you read a sentence!" ”

Gu Ling'er nodded, and Chi Yu began to recite the incantation.

Gu Linger learned from him to read it.

Then, an incredible scene appeared.

Suddenly, a red light appeared in the formation, surrounding Gu Ling'er and Tianling, and there seemed to be some kind of connection between their master and servant.

"Blood!" Chi Yu said.

"You actually know this forbidden technique!" Tianling exclaimed.

"You are not an ordinary spirit pet, don't use this, I don't worry!" Chi Yu said.

This formation, combined with blood, can make Tianling unable to escape from the contract made with Gu Ling'er, and he is not afraid that it will back, once it backspawns, it will immediately dissipate!

Gu Ling'er bit her finger, and the blood beads shone brightly in the formation, flying straight into Tianling's head, leaving a red mark in the center of its head.

The curse seal also flew into the primordial spirit of the Heavenly Tomb layer by layer, binding and suppressing it.

Tianling didn't know what was going on, so he didn't move for a long time.

Chi Yu shouted, "If you break your oath, you will be destroyed!" He knew that this demon king would not surrender so lightly, fortunately, he added a mark to the blood in advance, otherwise he would have to be rebounded by it, Gu Ling'er's cultivation is still shallow, if he doesn't completely suppress this spirit pet, I'm afraid that he will be robbed of his body by it, and he will regret it when the time comes, "Surrender quickly!" ”

The aura around Tianling's body was shocked, and then it slowly weakened, and the imprint was engraved into the depths of its Yuan Spirit.
