Of course, the seven major runes: Invisibility Rune, Body-Stabilizing Rune, Sealing Rune, Wind Stabilizing Rune, Fire Extinguishing Rune, Water Stabilizing Rune, Hard Earth Talisman, do not require many Points.

However, the Nine Bends Yellow River Array, which is now a second-tier talisman array, can cover an area of three hundred and sixty meters. If upgraded, it can cover three thousand six hundred meters, equivalent to enveloping a small mountain. If outsiders wish to destroy the Nine Bends Yellow River Array, it won't be that easy.

However, now the Nine Bends Yellow River Talisman Array is second-tier, and upgrading it to third-tier requires a full one million Points. Zhang Chen needs to think about it carefully.

After Zhang Chen calculated for a while, he suddenly realized that his Skill Points were somewhat insufficient.

Zhang Chen's gaze shifted to the Qi Cultivation Technique. To him, the most important was the Qi Cultivation Technique, which is the foundation of cultivation. The Qi Cultivation Technique should be upgraded first.

At this time, Zhang Chen's Qi Cultivation Technique was at the Sixth Heaven, requiring thirty-two thousand Points.

[Skill 7 (Entry-level): Qi Cultivation Sixth Heaven (0/32000)]

"Upgrade!" Without thinking, Zhang Chen clicked to upgrade. He now had five million Points, feeling quite proud.

[Skill 7 (Entry-level): Qi Cultivation Seventh Heaven (0/64000)]

In Zhang Chen's body, a petal of the lotus flower condensed from illusion to reality.

[Skill 7 (Entry-level): Qi Cultivation Eighth Heaven (0/128000)]

A section of the flower stem solidified.

...

[Skill 7 (Entry-level): Qi Cultivation Eleventh Heaven (0/1024000)]

The flower bud solidified into reality.

...

[Skill 7 (Entry-level): Qi Cultivation Twelfth Heaven (Perfection)]

[Points: 3112000]

At this time, half of Zhang Chen's five million Points vanished almost instantly, leaving only three million one hundred twelve thousand Points.

"Not nearly enough."

Zhang Chen's eyes turned to the Golden Finger Interface. The Qi Cultivation Technique was now at the Twelfth Heaven, in a state of perfection, and could not be further upgraded.

Meanwhile, in Zhang Chen's Forehead Ancestral Acupoint, the Cyan Lotus's leaves had fully solidified into reality, appearing as a real lotus, quietly perched in the Forehead Ancestral Acupoint. The lotus looked real, like pure jade, surrounded by a hazy Qi of Chaos, constantly flowing. Within the bud, the Golden Scissors continuously flipped and soared.

"Once the Qi Cultivation Technique reaches perfection, can it not be upgraded any further? I thought all skills could be upgraded indefinitely." Zhang Chen's gaze fell on the Qi Cultivation skill, a thoughtful look in his eyes: "I previously thought perhaps I could take a shortcut, ignore the manual and directly upgrade the Qi Cultivation Technique to a higher level using Points, but my plan failed. To reach a higher level, I still need to find the manual."

Zhang Chen pondered constantly: "I really don't know what the cultivation mantra of the higher levels of the Qi Cultivation Technique is. It probably isn't just continuing the Qi Cultivation. If it were, I should be able to upgrade directly using Points without needing the manual."

Zhang Chen judged that the next stage of cultivation would definitely be a different realm.

The Qi Cultivation Technique in Great Perfection, Zhang Chen's magical power surged mightily, multiplying many times over.

Zhang Chen's gaze scanned all his skills. With over three million Points remaining, he must use the remaining Skill Points wisely, without any wastage.

Zhang Chen's gaze fell onto the second skill, Blood Control Technique, a skill he had long wanted to upgrade, but previously the Points had always been insufficient. Now having enough Points, he naturally chose to upgrade it this time, as it was crucial to his survival ability.

[Skill 3 (First-tier): Transformed Blood Bat (0/1000000)]

Zhang Chen saw that the third skill required a full one million Points, and without hesitation, he clicked to upgrade.

As the one million Points were deducted, the Blood Control Technique twisted and transformed on the Golden Finger Interface:

[Skill 3 (Second-tier): Limb Regeneration (0/10000000)]

[Note 1: Severed limbs can grow back.]

[Note 2: Excludes the head]

Zhang Chen looked at his own Blood Control Technique, his gaze falling on Limb Regeneration. Disappointment flickered in his eyes: "Unfortunately, it wasn't the Blood Rebirth I wanted. But Limb Regeneration is already quite remarkable; at least in my future travels, it greatly enhances my survival rate."

At this moment, Zhang Chen's Crystal Core vibrated. Zhang Chen felt that a mysterious light flashed from his Crystal Core, sprouting blood-red runes that linked together to form Order Chains etched inside the Crystal Core. Subsequently, an inexplicable notion arose within him: wherever his body was injured, except for the head, it would rapidly regenerate.

Zhang Chen scanned his Golden Finger Interface, finally settling on the Nine Bends Yellow River Talisman Array. After pondering for a moment, he abandoned it, as even if upgraded, it wouldn't greatly enhance his combat power.

What would be the difference between three hundred sixty meters and three thousand six hundred meters?

Those capable of being entrapped by the Nine Bends Yellow River Array wouldn't find much difference between the range. And for those ancient beings controlling Heaven and Earth Energy, a three thousand six hundred meters Nine Bends Yellow River Array would still be too fragile.

Zhang Chen's eyes scanned the recently acquired runes, feeling that the Invisibility Rune, Body-Stabilizing Rune, and others were his best tools to turn the tables at critical moments in a confrontation.

The fifth-tier Invisibility Rune required eight hundred thousand Points. Without a second thought, Zhang Chen allocated Points to upgrade it.
