Just when Jiang Fei had been living in the training ground for two and a half months, Domingo suddenly appeared in front of him.

"Ah Fei, the boss is here to pick you up. "Domingo has really hurt to death these days, he has suffered heavy losses in the Gemini Galaxy, and after coming back, Jiang Fei has used the training ground endlessly, the consumption is quite amazing, if it weren't for Jiang Fei's identity as a relation, Domingo would have been driven out long ago.

Today, Oduka finally came to pick up Jiang Fei, which made Domingo breathe a sigh of relief, if Jiang Fei was allowed to stay here permanently, the cost of the training ground alone would be enough for him to bear.

"Oh!oh!" Jiang Fei nodded, and although he was reluctant, he followed Domingo out of the training ground.

Originally, in Jiang Fei's plan, he planned to stay in the training ground, delaying time by slowing down the time flow, so that 0541 could study the use of the black hole heart.

As long as the heart of the black hole can be used, then Jiang Fei's will core can be restored in minutes, and his domain can naturally be restored.

But now that Oduka has come to pick him up, Jiang Fei naturally can't continue to stay in the training ground.

"Master Instructor!" Jiang Fei saluted Oduka very respectfully.

"Well, that's good!" Oduka looked at Jiang Fei, and then nodded with satisfaction, he was very satisfied with Jiang Fei's progress, after all, Jiang Fei's previous basic combat strength was only 65,000, but now it is as high as 120,000, which is equivalent to doubling!

It's just that Oduka couldn't notice that Jiang Fei's domain was temporarily abolished, so he didn't know that Jiang Fei's strength was falling instead of rising at this time.

"Let's go, Domingo, I've made a note of this favor!" Oduka nodded at Domingo.

"Boss, this is what I should be. Domingo smiled, and waited for Jiang Fei to leave the relation, his heart was a lot happier, although this operation made him suffer heavy losses, but Jiang Fei was at least a comrade-in-arms who shared weal and pain, with this feeling, he would naturally be able to make friends with the big man behind him in the future, which was more important than anything else.

Following Oduka onto his ship, Jiang Fei left the planet Ipssaurus, and soon the ship entered phase space and returned to Redstone a day later.

"Master Instructor, what are we going to do next?" Jiang Fei asked curiously.

"It's graduation in five days, and you have to attend it too!" said Oduka lightly.

"Graduation ceremony?" Jiang Fei was stunned, you must know that he has only been enrolled for a few days, why did he stop working?

"You're my student now, and I'm only teaching the graduating class!" Oduka said with a glance at Jiang Fei.

"Huh?" Jiang Fei was a little dumbfounded.

"In the last five days, I will open the training ground for you, if you have any requirements, you can mention it, but you have to give me a good performance at the graduation ceremony!" Oduka said lightly, he was very relieved of Jiang Fei's strength, after all, Jiang Fei could reach one and a half million combat power with the support of the realm, and this value was enough for him to kill the other graduating students in seconds, so Oduka was very confident in this graduation competition.

However, what Odukawan didn't expect was that Jiang Fei, who was his killer weapon, lost his domain, and now he only has 120,000 combat power, which is definitely the bottom of the graduating class!

"Thirty times the speed of time, it doesn't matter if anything else!" Jiang Fei immediately replied, the danger of the graduation ceremony was very high, and the mortality rate reached twenty percent, which means that one-fifth of the graduation life would not be completed until the ceremony, with Jiang Fei's current strength, he was almost certain to die.

Therefore, Jiang Fei can only hope for the Heart of the Black Hole, he hopes to enlarge the time of these five days in the training ground into five months, so that 0541 has enough time to crack the Heart of the Black Hole, as long as he can use the energy in the Heart of the Black Hole, Jiang Fei will immediately return to his peak state.

"Yes!" Oduka agreed very happily, this time in the graduating class, there were also many masters in other classes, which made Oduka not very confident in this championship, until he found Jiang Fei!

So in order to win the championship, as long as Jiang Fei is willing to help him, Oduka doesn't mind Jiang Fei making some small requests.

As soon as he came out of the airport, Jiang Fei went straight to the training ground, and then he immediately started the thirty-fold time acceleration.

In the training ground, Jiang Fei was honing his swordsmanship while waiting for the news of 0541, time passed quickly, three months passed in a blink of an eye, and three days were spent in reality.

"It's been two months, and I don't know what's going on with 0541!" Jiang Fei muttered to himself, but he didn't dare to disturb 0541, for fear of delaying the testing process again.

Time passed day by day, and it was not until less than a month before Jiang Fei left the training ground that the voice of 0541 sounded from Jiang Fei's heart again.

"Congratulations to the captain! I made it!" 0541's first words were good news!

"Oh, great! Tell me more about it!" Jiang Fei was also very excited in his heart.

"I've done tens of billions of simulations and nearly 100,000 actual experiments on this black hole heart, and I've finally determined two effective ways to use it!" 0541 said.

"Which two?" Jiang Fei asked.

"The first is to use the instrument to excite and guide it, so that it can steadily output energy to the outside world. "The first plan of 0541 is very conventional, but it is also very safe, and there is almost zero risk of obtaining a permanent and stable energy source.

"What about the second one?" Jiang Fei asked curiously.

"The second one is a little risky, but the returns are higher!" 0541 said.

"Tell me about it!" Jiang Fei asked with interest.

"The second is the fusion of living organisms, just like fusing the core of energy, integrating the heart of the black hole into the body, in the words of a martial artist, is to open up a second dantian!" 0541 said.

"What about the risk?" Jiang Fei asked.

"You have to carefully control the energy output when using it, if the energy output gets out of control, there will be danger!" replied 0541.

"What danger?" Jiang Fei asked.

"There are two possibilities, the first is a strong explosion, fused with the heart of the black hole of the creature incarnation of the white hole, frantically radiating energy outward, until even he is consumed with himself. Another possibility is to incarnate a black hole and annihilate everything, including the creature itself that fuses the heart of the black hole. 0541 replied.

"To put it bluntly, once you get out of control, you're dead, right?" Jiang Fei asked.

"That's right!" 0541 nodded in confirmation.
