The soft and cute voice of the meat ball is resolute and very serious.

"Hiss~"

The one-horned giant snake can understand the communication between them, and it does not allow Mu Yuyun to take risks, if there is really an accident, the little prince may also lose his life.

Mu Yuyun glanced at the listless one-horned giant snake, and then at the meat ball that was staring at her from the side.

Anyway, Xiao Hei must be saved, he has always defended himself so much, what about a drop of blood!

"Meat ball, what's next?"

Mu Yuyun swung his sword and stabbed it into his chest without hesitation, and instantly blood gushed out and dripped towards the one-horned giant snake.

“…… Master, you drop the blood of your heart on Xiao Hei's horn, recite a spell, and then you can make a contract......"

Seeing that Mu Yuyun stabbed the sword at him without hesitation, the meat ball was heartbroken, but it couldn't let the master's blood go to waste.

After Xiao Hei realized Mu Yuyun's movements, it no longer hesitated, and raised its head with difficulty to receive the blood dripping from Mu Yuyun with its own horn.

No one noticed that a drop of Mu Yuyun's heart blood slipped into the space ring in her hand, and a trace of red light flashed on the space ring, and then it returned to its normal appearance.

Seeing that Mu Yuyun's face had appeared pale, the meat ball immediately licked Mu Yuyun's wound with his tongue, and his saliva had the function of healing.

After accepting Mu Yuyun's heart's blood, a golden ancient contract formation suddenly appeared under the feet of one person and one snake, and the light emitted by the ancient formation tightly wrapped the two of them inside, and then the golden light flashed.

The face of the meat ball was rarely seen staring at the scene in front of him very seriously, in case Mu Yuyun had an accident.

After the golden light, Mu Yuyun and the one-horned giant snake appeared.

"Master, are you alright?" The meat ball asked in a milky voice, and the panda's face was worried.

Mu Yuyun shook her head, she glanced at the one-horned giant snake on the ground and said, "Why hasn't Xiao Hei woken up yet?" ”

"Master, let's move aside first, Xiao Hei seems to be about to be promoted!"

Not long after the meat ball finished speaking, when the two of them had just walked three or four meters away, the one-horned giant snake lying on the ground suddenly floated into the air.

It was surrounded by bits of golden light, vaguely conscious.

"Hiss——! ～”

The one-horned giant snake suddenly roared in pain, and Mu Yuyun was very worried.

"Blackie won't be anything, right?"

"Master, don't worry, it's like this when the Warcraft is promoted, Xiao Hei should be fine, but Xiao Hei's promotion seems to be different from other ordinary Warcraft?"

"Could it be because it's the Serpent King?"

"No, it won't."

The meat ball shook his little head, even the snake king would not be treated so differently, and the promotion of the one-horned giant snake seemed to be a little more dangerous.

"Hiss ——!"

As the two of them were communicating, the unicorn suddenly let out a more intense roar, and its massive body burst into the sky.

"Is it really going to happen?"

"Don't worry, master, it's definitely going to be fine!"

The meat ball didn't have a score in his heart, after all, a situation like the one-horned giant snake was too rare, and for now, it could only comfort Mu Yuyun not to worry too much.

"I'm afraid of the little black it ......"

Mu Yuyun was worried that the unicorn giant snake had just gone through the battle and didn't have the energy to upgrade.

"Look, master!"

The meat ball suddenly hugged Mu Yuyun's leg with his claws, and then stretched out his hand and pointed at something flying in the sky in the distance.
