According to rumors, collecting twelve sky stones can make people advance to level 13 immediately. No one has confirmed this rumor.

However, Xiao Yu wants to try it. If it can succeed, it will be a huge opportunity for Xiao Yu's followers.

For other Shadow Killers, these sky stones are useless. Because the level of themselves and their followers has long exceeded the thirteenth level, and they cannot use this sky stone at all.

But for Xiao Yu and his followers, these sky stones are simply life-saving existences.

If successful, Xiao Yu and his followers will all be upgraded to one level. In this way, their team of No. 0 will have a huge improvement in overall strength.

If the facts prove that the sky stone can really make people become a level thirteen abilities, then at that time, in addition to taking out twelve sky stones to complete the goal, the rest can also be used to enhance the strength of Xiao Yu and his followers.

Xiao Yu had already discovered that this trip to the top of the Tower of Tongtian was not only going through a series of difficulties, but actually it was an extremely beneficial exercise for everyone.

If you can seize the opportunity, everyone's strength can be improved at a faster speed than usual.

For example, after Xiao Yu's followers advanced to level 12 through various means, their cultivation speed gradually slowed down due to lack of external objects, and many people even stagnated.

However, after entering the Tower of Heaven, Xiao Yu was surprised to find that their strength was growing rapidly through repeated battles.

This growth rate even exceeded Xiao Yu's perception.

For example, fighting a giant dragon in the third level of space. Although Xiao Yu's followers did not fight directly, they just kept killing the seriously injured giant dragon. When they were exhausted, they absorbed the level 14 energy beads to recover.

During this process, Xiao Yu found that after each exhaustion, he absorbed the energy beads and recovered, everyone's attack power and endurance power were slightly improved.

Although this improvement is subtle, it is enough to surprise you if you have such an improvement in the day.

If you continue to improve at this speed, even if there is no Tianshi, Xiao Yu believes that he and his followers can quickly enter level 13.

However, the growth rate of strength will never be too fast. It is possible to use the Sky Stone to upgrade everyone to level 13. Xiao Yu will never give up such an opportunity.

Xiao Yu did not waste the twenty star warriors. After all, they were level 14 warriors and were all subdued by Xiao Yu and included in the Dragon Roar Bracelet.

Then Xiao Yu was waiting for news about the twelve demon lords in the hall of Sky City.

I have to say that the twelve demon lords were still very fast. Not long after, they began to send news that the twelve attributes of the sky stones were collected, and they were still collecting them.

Xiao Yu nodded and asked the demon lord to send all the sky stones he had collected.

The twelve sky stones were placed together and presented in different boxes.

After instructing three level 15 giant dragons and twelve demon lords to take care of them in the Sky City, Xiao Yu brought a box containing the sky stone into the interior of the Dragon Roar Bracelet.

Here, Xiao Yu gathered all his followers together.

"It is said that collecting twelve heavenly stones can make people become level 13 abilities as soon as possible. This advancement time is a lot, even for only one minute. However, this rumor has not been confirmed yet..." Xiao Yu said, "In the past, because no one has collected twelve heavenly stones, it cannot be confirmed.

Now, we have really collected twelve sky stones, so now we need to verify it..."

Verification, needless to say, has certain risks.

If you succeed, you will naturally be happy. If you fail, you may make a mistake.

Therefore, it is a very serious question to verify the first one.

"I think I can try it!" Xiao Yu smiled, "I have always been lucky, and now I have received extra points in luck, maybe I can succeed!"

"No!"

"Absolutely not!" Others objected!

"Xiao Yu, you can't do it." Wu Qi also said, "If it were us, if it failed, it would fail, and if there was a problem, it would be nothing to worry about. As long as you are still alive, everything will have hope.

But if you have a problem, then everything is over, and even if we are alive, there is no meaning. Therefore, this matter must not be done by you!"

Others were also scrambling to experiment on their own.

In the end, this matter fell on Xiang Xiaomo. She persuaded Xiao Yu and obtained twelve heavenly stones.

Now, what Xiang Xiaomo needs to do is to place the twelve heaven stones together in a certain order, and then drip his own blood on it.

Seeing Xiang Xiaomo, who was like a porcelain doll, put the twelve sky stones into a circle, Xiao Yu couldn't help but become nervous.

Needless to say, the others were nervously watching Xiang Xiaomo's every move. Her current actions involved the overall strength of these people and the hearts of everyone.

After Xiang Xiaomo put the sky stone together, he turned his head and looked at Xiao Yu deeply, and said in a clear voice: "Brother, I'm going to start!"

Then, Xiang Xiaomo took out a silver dagger and stroked his little white little tail finger. A drop of crystal-like blood as red jade slipped down and fell on the Virgin Sky Stone corresponding to her attributes.

Everyone's eyes were looking at the blood beads on the sky stone without blinking.

The blood beads turned red and fell on the sky stone. The color gradually turned green and crystal clear, just like a dewdrop on a clear lotus leaf trembling slightly.

The color changed from red to green, and the blood beads quietly disappeared and merged into the sky stone. Then, a colorful light bloomed from the Virgin Sky Stone and extended towards the rest of the sky stones...

Twelve sky stones then burst out with beautiful light, and then all the sky stones were suspended in the air and rotated around Xiang Xiaomo's body...

The rotation speed was so fast that it could be recognized by the human eye. In an instant, everyone was in front of their eyes, and all the images became blurred. Only a colorful light was seen in a hazy way, but the specific details were not very clear.

Xiao Yu had already opened his golden eyes, and at this time two golden lights shot out from his pupils, piercing through the hazy colorful light as if it were physically solid, clearly reflecting what happened inside the colorful light in Xiao Yu's mind.

In the center of the colored light, twelve sky stones were rotating at high speeds that were difficult to recognize with the naked eye. During the rotation, all the sky stones began to separate and turned into clusters of light, blending with each other...
