This time, it wasn’t as easy as the first time, nor did it spark like the second time. Instead, it stayed on the surface of the giant bone, the flying sword kept trembling, and upon closer inspection, the tip of the flying sword was penetrating the giant bone at an extremely slow speed.

Xu Ran used his fingers to form techniques, white airflow kept pouring out from his fingertips as Innate Qi was continuously injected into the pocket-sized flying sword.

Like this, a whole hour passed, and the extremely hard white jade giant bone barely allowed a thread of marrow to flow out.

"It’s out, it’s out!!"

Xu Binghu, who had been watching from the side, exclaimed at this scene.

That one hour was truly torturous for him as he couldn’t do anything but hold the bucket to collect the marrow. Watching intently, he became increasingly anxious.

Turning to Xu Ran, he saw sweat pouring down Xu Ran’s forehead, fingers trembling nonstop, and the Innate Qi around him had significantly diminished, indicating how much effort this bone cutting took.

"Hu!!"

Suddenly, Xu Ran pointed his fingers sharply to the sky, stirring a gust of fierce wind. The pocket-sized flying sword, halfway embedded in the giant bone, suddenly broke free, soared into the sky, then returned to hover above Xu Ran’s head. The flying sword’s surface emitted a faint golden glow.

"Xiao Ran, are you alright?" Lian Ji hurriedly approached, concerned as she saw Xu Ran drenched in sweat.

Xu Ran heard her, slowly raised his head, and a slight smile appeared on his face, seeming to have received a pleasant surprise.

He wiped the sweat off his forehead and replied, "I’m fine, on the contrary, I’m in a very good state!!"

That said, he looked at the white jade giant bone with bright eyes, full of anticipation.

It’s because he discovered that using the pocket-sized flying sword to cut the giant bone could swiftly enhance his Immortal Sword Skill, much faster than nurturing the Immortal Sword with Innate Qi. The speed was like a rocket, indescribable.

Although cutting the giant bone took an hour this time, the improvement in the Immortal Sword Skill was even better than a month’s hard cultivation. If it continues like this, it won’t be long before the Immortal Sword Skill reaches Great Success!!

With the Immortal Sword Skill at Great Success, the mysterious legacy can be unlocked, bringing unimaginable benefits, which is extremely important for Xu Ran who deeply needs time.

Xu Ran felt extremely excited in his heart, quickly sitting to meditate, restoring his breath, preparing for the next bone-cutting.

...

Three days passed just like that.

The scorching sun shone through the clouds into the Xu Family courtyard, stretching the shadows of several pieces of white jade bones on the ground long, as if they had never been cut.

At this moment, Xu Ran, drenched in sweat, with fingertips shimmering in white light under his control, trembled continuously with the pocket-sized flying sword, while Innate Qi kept bursting out, trying to push it a bit further onto the white jade giant bone.

"Buzz---"

"Buzz---"

"Buzz---"

The sound of the trembling pocket-sized flying sword kept echoing in the air, Xu Ran’s hands also trembling in response to the flying sword.

Finally.

Half a day passed again, and night fell.

"Boom----"

With a loud bang in the Xu Family courtyard, Xu Ran’s pocket-sized flying sword stabbed straight into the dirt, and the white jade giant bone was cut in two again, with marrow continuously flowing out.

Xu Binghu, who had been standing by, hurriedly took the prepared big bucket and collected every drop of flowing marrow.

Seeing this, Xu Ran slowly exhaled a breath.

"The sixth cut is finally completed!!"

Over three days, Xu Ran had performed six cuts in total, with each cut taking longer, and this time, it took him a whole day.

A whole day, continuously using the pocket-sized flying sword to cut the giant bone, was completed with significant effort.

Subsequently, Xu Ran smiled, "But it’s all worth it, the training of the first flying sword is already at a masterful level, and its power is nearly ten times stronger than at the start, consuming less and less Innate Qi and Spiritual Qi, all achieved during bone cutting through hard cultivation!!"

Although these three days had been very arduous, they were nothing compared to the gains.

Xu Binghu continued collecting bone marrow on the side while listening to Xu Ran’s words, only pausing slightly, with no other reaction.

After all, such surprises had become commonplace. In those three days, every successful cut of the giant bone would enhance Xu Ran’s pocket-sized flying sword’s power by one level, consistently.

Lian Ji had tried several times to persuade Xu Ran to rest well, seeing him working so hard, but to no avail!!

However, seeing his son achieve such progress in three days, he, as a father, was equally excited.

Still, what was the origin of this white jade giant bone? A white bone left after death still had such a defensive mechanism?

"Xiao Ran, what kind of existence was this white bone giant bone before its death, to have such a defensive mechanism?" Xu Binghu asked, puzzled.

In fact, Xu Ran was also very interested and curious about this matter, but without any information, he could only guess.

"As they say, whosoever has fate shall obtain it. To encounter various adventures, one needs some luck and strength!"

"The bone’s miraculous defensive mechanism exists to prevent those who are not ordinary from wasting the marrow’s medicinal power!"

"That’s my guess!" Xu Ran added.

Xu Binghu nodded, "That’s probably the case!!"

After the conversation, all the marrow was collected. Standing up, he said, "I’ll put away the marrow first, Xiao Ran, you rest well!"

He then left the courtyard with the marrow and Lian Ji.

...

A month passed.

Daytime.

Xu Ran sat cross-legged in the yard, sweat dripping down, eyes tightly closed, brows furrowed, finger trembling as he continuously formed hand techniques. Innate Qi inside him overflowed ceaselessly, converging at the nearby pocket-sized flying sword.

Lian Ji sat beside, looking worriedly at Xu Ran, asking, "Husband, do you think Xiao Ran can succeed this time?!"

Xu Binghu reassured, "Don’t worry, what’s there that Xiao Ran can’t do? The past month, working tirelessly day and night cutting the white jade giant bone, his aura has been continuously climbing. Although the cutting time is getting longer, this ninth cut has taken seven days, but Xiao Ran succeeded every time, so just watch with peace of mind."

Xu Binghu held Lian Ji’s hands while his mouth spoke calmly, however his hands were trembling continuously.

It’s now been a month since Xu Ran started cutting the giant bone, originally three meters long, it’s now reduced to just thirty centimeters. Over the month, Xu Ran finally cut it to the last section.

In a corner of Xu Family’s courtyard, there were eighteen large barrels, each filled with white marrow. Adding the last section’s marrow, it would make a total of twenty barrels.

Next to these eighteen barrels, there was also a two-meter-high tank filled with crystal-clear water, so clear that even at the two meters depth, the bottom was visible.

This tank contained dew collected by the entire Great Wilderness Border Village for Xu Ran, which took a whole month. Now, everything was ready, only waiting for Xu Ran to cut open the last giant bone.

"Bang----"

With a burst of sound, only to see the white air flow on Xu Ran’s body burst out fiercely, sweeping around, stirring Huang Sha, a streak of white light tinged with gold slowly appeared above Xu Ran’s head, spreading an aura of destruction.

Immediately, Xu Ran’s eyes suddenly opened wide, and he spoke.

"Succeeded!!"
