The three of them just made a simple agreement, but it made the atmosphere of the whole room extremely warm, and Mu Tian's face became much ruddy, as if he had opened the depression in his heart for many years.

After a while, the three of them withdrew their hands one after another, while Mu Tian put the ring directly in the black box, together with the spirit core, staring intently, for fear of missing a moment.

The three of them waited while looking at the black box.

I saw that a trace of black gas appeared on the surface of the spirit core in the box, and then floated into the ring, and with the inhalation of the black gas, the surface of the ring flashed with a slight silver light.

Seeing this, Mu Tian's face was happy, and after a while, the black gas on the black box slowly dissipated, and then, there was no reaction.

As the light on the surface of the ring dissipated, the joy on Mu Tian's face also dissipated.

"It seems that the dark attribute spirit core of the third-order nine-star can't unlock the seal!" Then, Mu Tian sighed and closed the black box directly.

Mu Tian pondered for a moment, thoughtfully, as if he had made some kind of decision, turned his wheelchair, got closer to Mu Xiyun, and handed the black box to Mu Xiyun.

Mu Xiyun was slightly stunned, a little unclear.

Seeing that Mu Xiyun didn't take it, Mu Tian explained: "For the current Mu family, there is no way to take out the fourth-order spirit core, and the only one who can get the fourth-order spirit core is you, although I don't know what the origin of your master is, but with his ability, it shouldn't be difficult to get one!"

"I don't care about what's in this ring, so you take it and break the seal when you have the chance. Mu Tian looked at the two, smiled gently, and said, "As for the things inside, just take it for the two of you." ”

Mu Xiyun took the box, and suddenly, as if he remembered something, his eyes lit up suddenly, and he looked at Mu Tian: "I know where there is a fourth-order dark attribute spirit core!"

Mu Tian: "??"

Mu Xin'er: "??"

Hearing this, Mu Xin'er and Mu Tian were both stunned, and looked at Mu Xiyun with a puzzled expression.

"There is a hunting operation in the Thousand Machine Pavilion, and the target they hunt should be the fourth-order dark attribute Geocentric Black Jiao. Looking at the two of them with a smile, Mu Xiyun explained.

"How do you know that they are hunting fourth-order geocentric vinyl?" Mu Xin'er leaned slightly, looked at Mu Xiyun and asked suspiciously.

"Hey...... I heard from the master that in a few days, the Thousand Machine Pavilion will issue a summoning order, summoning many powerhouses from Xiaoyao City to go to Heiyun Mountain and kill the Black Jiao in the center of the earth!" Mu Xiyun grinned.

Then, Mu Xiyun stroked his chin with his hand, pretended to be pensive, pondered for a moment, and continued: "If it is just the geocentric vinyl of the True Spirit Mirror, there is no need to launch any summoning order at all, any of the three major families can directly take it down, obviously, it is at least the geocentric vinyl of the geocentric of the geospiritual mirror, and it may also be the geocentric vinyl of the mid-stage realm." ”

Hearing Mu Xiyun's explanation, Mu Tian nodded slightly, quite agreeing with this analysis, and then said with a slight helplessness: "Although their target is the fourth-order Earth Center Black Jiao, but the Thousand Machine Pavilion has taken such a lot of pains, I'm afraid they won't give it to us!"

"Hey...... Father doesn't have to be so pessimistic!" Mu Xiyun grinned at the corners of his mouth, and the smile became even stronger.

Hearing Mu Xiyun's words, Mu Tian was puzzled for a while, and then his face showed a little abruptness, and said, "Yun'er, could it be your master......

Although Mu Tian didn't finish speaking, Mu Xiyun of course knew what Mu Tian wanted to say, and then nodded at Mu Tian and said, "Exactly, master, he just wants to participate in this hunting operation!"

"Although I don't know your master's cultivation, for a person who can ask for 400,000 spirit stones at will and can awaken the dark spirit vein, his cultivation must be extremely profound, and there shouldn't be much of a problem with this hunt. ”

Mu Tian raised his head slightly, and when he spoke, he unconsciously gave birth to a kind of awe for the strong: "You can have such a powerful master, I am very pleased for my father, now, you are his disciple, and you are still valued by him, and you are more proud of your father!"

Hearing this, Mu Xiyun, who was as thick-skinned as Mu Xiyun, couldn't help blushing, and was a little embarrassed!

Mu Xin'er on the side couldn't help but smile when she saw this scene.

"Hahaha!" Seeing Mu Xiyun so embarrassed, Mu Tian smiled heartily.

"Hmm... It's not too early, so go back and rest first! Mu Tian glanced at the sky outside the door, turned to look at the two, and smiled gently.

"Wait, there's one more thing!"

Mu Tian: "??"

"This time, there is one more important thing. Mu Xiyun took a few steps forward, came to Mu Tian's side, smiled, and the excitement on his face was not false in the slightest: "That is to treat my father's injuries!"

"Yun'er, you said you would help me heal my injuries?"

"Well, although I have only been practicing with my master for more than a month, I am no longer the Mu Xiyun I used to be. Mu Xiyun grinned again, and said proudly: "I'm also a little miracle doctor now!"

After speaking, he glanced at Mu Xin'er, who saw this, immediately understood, and then said very cooperatively: "Yes, my brother is now a little miracle doctor, I have seen it with my own eyes." ”

"Huh?" Mu Tian looked confused, when did Mu Xiyun become a miracle doctor, and he, a father, didn't even know it.

"As long as you use the right method and the right medicine, you can do it. Mu Xiyun walked behind Mu Tian, put a hand on his right shoulder, and a trace of prison black qi quietly entered Mu Tian's body, carefully feeling Mu Tian's physical condition.

If it was someone else standing in front of Mu Tian at this time, even if he was a True Spirit Mirror powerhouse, he wouldn't want to inject the aura into his body, although Mu Tian was crippled, but the most basic resistance was still there.

However, for Mu Xiyun, Mu Tian would not be on guard at all, so Mu Xiyun could easily probe Mu Tian's body.

In just a moment, Mu Xiyun withdrew his hand, his face was happy, and he was secretly glad in his heart: "Fortunately, the injury has not deteriorated, otherwise I would have started to heal after getting this spirit jade, which is really worth the loss!"

"Ahem!" Suddenly, a new row of silver needles suddenly appeared in Mu Xiyun's hand, and then he looked at Mu Xin'er and coughed dryly.

Seeing this, Mu Xin'er seemed to understand what Mu Xiyun meant, her pink lips were slightly upturned, her hands were on her waist, and she looked a little unhappy when she looked at Mu Xiyun's eyes, and finally walked out of the room helplessly, but when she went out, the unhappiness on her face was already full of joy, and she was a little relieved.

"Father, I'll help you to the bed first. Mu Xiyun hugged Mu Tian's arm and helped him walk to the bed step by step.

Although Mu Tian is disabled, he can barely walk around if someone supports him.

"Father, eat this elixir!" Mu Xiyun took out a Gathering Spirit Pill from the space ring and handed it to Mu Tian.
