After a dozen or so breaths, Lin Yun broke through to the mid-stage of the ninth level.
That's incredibly fast.
Under normal circumstances, Lin Yun estimated that it would take several months to achieve this progress, but now, he has achieved it in just a dozen breaths.
"No wonder this blood sword could play such a significant role in battle..."
The moment he broke through, Lin Yun gasped in shock.
"Buzz—"
A breakthrough wave emanated from Lin Yun, causing an anomaly in the world, but it was quickly suppressed by Lin Yun.
He didn't want Mingdu, who was not far away, to discover that his martial arts level had increased.
"However, the blood sword absorbs blood, and the resulting killing intent is too strong. Fortunately, my strength is not that of an ordinary ninth-level cultivator, otherwise, I would probably have suffered a qi deviation..." Lin Yun paused and said in a low voice.
"I'm improving, and the Blood Sword is improving too. Moreover, the Blood Sword's improvement seems to be even greater. Under such circumstances, I'm afraid I won't be able to improve much..." Lin Yun pondered.
Now, it's not a matter of how much blood he has, but rather that if he loses control, he might end up like that old man in black.
Only then did he realize why the Heaven-Shattering Blood Sword didn't use it to infinitely enhance its strength, and why it handed the Blood Sword to the old man in black during that battle.
Because, no matter how strong the Blood Sword is, it probably can't control the Heaven-Shattering Blood Sword.
"It's a pity I didn't obtain that Heavenly Evolution Flower. Otherwise, my martial arts realm could have advanced three levels without any side effects. At that time, my strength in all aspects would have increased, and I could have used the power of the Blood Sword to advance to an even higher level..."
Lin Yun felt a pang of regret.
This is similar to the principle of geometric progression; one plus one does not equal two, but rather three, or even four or five.
The blood continues to be absorbed.
After about twenty breaths.
Lin Yun's body trembled again.
His martial arts realm has already broken through to the late stage of level nine.
This breakthrough speed is truly extremely fast.
whoosh—whoosh—whoosh—
He sat cross-legged in a closed training room, surrounded by countless energy crystals that had formed a powerful energy vortex that rapidly surged into Lin Yun's body.
Although the power of the Blood Sword can greatly increase his strength and allow him to break through his martial arts realm, he still needs to absorb a large amount of the power of heaven and earth to stabilize his realm when he breaks through.
When one breaks through, one can trigger a reaction from the power of heaven and earth. It is also a natural reaction that occurs when one's cultivation realm breaks through and resonates with heaven and earth.
However, not wanting to alert Mingdu not far away, he could only use these energy crystals to replenish his energy.
Fortunately, the power of the Blood Sword could provide a large amount of energy, and in addition, Sheng Er controlled the surrounding power of heaven and earth, so the sound of his breakthrough did not spread.
"Kill! Kill! Kill!"
"Slaughter all living beings under heaven!"
"When I become stronger, you will become even stronger. Together we will reach the pinnacle and sweep across the world!"
At the center of the vortex, the Blood Sword continuously transmitted this information to Lin Yun, making Lin Yun's blood boil and increasingly difficult to suppress.
"If you keep sending messages like this, I'll destroy you..."
Lin Yun's eyes reddened as he spoke in a low voice.
He knew that this blood sword possessed a high degree of spirituality and could understand his words.
At the late stage of the ninth level, his current strength is estimated to be only enough to fight against cultivators at the peak of the tenth level.
He wanted to fight Mingdu and his group, so his strength needed to be at least at the tenth level.
Even reaching the initial stage of level ten might not be enough.
Right now, there's still a long way to go.
However, perhaps due to absorbing a large amount of blood, the Blood Sword was too excited and only emitted a series of excited chirps, without restraining itself at all.
"It seems we have no choice but to give up..."
Lin Yun let the blood sword in his hand absorb blood for a while longer, then sighed softly.
At this rate, he will never be able to advance to level ten.
Needless to say, that's a higher level.
"elder brother!"
"elder brother!"
Just then, two childish voices rang out, and two figures appeared in the room.
Lin Yun opened his eyes.
I saw two adorable little children, about five or six years old, wearing red bibs and looking very delicate. One was a boy, and the other was a girl.
It was when Lin Yun left Earth that the Holy Mother entrusted him with taking away the two spirits, Xiao Lan and Xiao Bai.
After leaving Earth, Lin Yun arranged for the two little guys to merge into a good object and gave them a large amount of spiritual crystals so that they could cultivate properly.
Occasionally, he would also purchase some resources that were beneficial to spiritual cultivation from the cosmic trading system and give them to the two little ones.
He remembered that some time ago, the two little guys had already reached the seventh level.
Spiritual beings are difficult to cultivate, which is quite remarkable.
As the Holy Mother said, these two little ones are exceptionally talented.
Both being born with yin-yang spiritual bodies, the two little ones cultivating together are like divine assistance.
"Why did you all come out?" Lin Yun asked.
"Little Blue and I sensed the aura of a powerful spirit, brother, isn't it listening to you?" Little White looked at the blood sword in Lin Yun's hand and asked in a childish voice.
"Is it the spiritual object you're talking about?" Lin Yun was taken aback.
"Mmm." Little White nodded repeatedly.
“Brother, do you need to use this sword? Xiao Lan and I sensed that the spirit inside this sword is not as powerful as us. Grandma told us how to deal with other spirits, so we can help you deal with it!” Xiao Bai then said.
"You can handle it?" Lin Yun suppressed the murderous intent in his mind, his tone was very calm, but a hint of surprise flashed across his face.
"Mmm, brother, is it not listening to you? Little Blue and I will help you teach it a lesson!" Little White nodded vigorously and said in a very cute way.
"Won't this affect its effectiveness?" Lin Yun asked hesitantly.
He wanted to use the Blood Sword to improve his martial arts level, but if the Blood Sword's power disappeared or was suppressed, he probably wouldn't be able to do so.
"It should have some impact, but not a big one..." Xiaobai bit her little finger, thought for a moment, and said, "However, Xiaolan and I can make it listen to its brother and help him as much as it can..."
"Okay, you guys do it!" Lin Yun nodded.
Anyway, without Xiaobai and Xiaolan's help, he probably wouldn't be able to use the Blood Sword to the end, so he might as well let Xiaobai and Xiaolan give it a try, even if it's a last resort.
"Okay, brother, you wait here," Xiaobai said with a smile.
"Buzz—"
The next moment, the two transformed into a streak of light and swiftly pierced towards the blood sword in Lin Yun's hand.
At this moment, Lin Yun realized that Xiao Bai and Xiao Lan had reached the peak of the seventh level of spirit body, and were only a little bit away from breaking through to the eighth level of spirit body.
Spirits only have levels, not specific tiers. Spirits of the same level have similar strengths and weaknesses. Their specific strength depends mainly on the magical artifacts they refine. If the artifacts are powerful, they are powerful; if the artifacts are weak, they are weak.
If a spirit refines a powerful magic weapon, it can easily defeat enemies of a higher level.
Just like the Holy Mother, the Mountain-Moving Whip she refined was a very powerful magic weapon.
Generally, the strength of a spirit is rarely greater than that of a cultivator of the same level, even the lowest level cultivator.
However, that Holy Mother could handle many level ten cultivators. According to her, she had not yet fully refined the Mountain-Driving Whip; otherwise, her strength would be even greater.
For a spirit to refine a magical artifact, a certain degree of compatibility is required. If the compatibility is high, it is easy to refine the artifact. If the compatibility is low, it is difficult to refine the artifact. In fact, once the artifact is refined to a certain extent, it cannot be refined any further and will never be able to unleash the full power of the artifact.
"I wonder what level the spirit within this blood sword is, and whether Xiaobai and Xiaolan can handle it..."
Lin Yun looked at the blood-stained sword in his hand and thought to himself.
He had known for a long time that there was a spirit within the blood sword. However, the materials of this blood sword were not simple and of an extremely high grade, so he was unable to detect the specific level of the spirit within it.
However, the power level of the Blood Sword was at the peak of level ten when he used it, and now he feels it breaking through to level eleven more. He estimates that even if the spirituality within the Blood Sword is weak, it won't be that weak.
