Seimei finished his routine patrol and found an opportunity to enter the cave space.
Seeing Seimei approaching, the shadow clone stationed here spoke.
Seimei nodded, casually responding, and then let the shadow clone dispel itself.
The next moment, a surge of chakra flowed into his body along the ethereal connection.
Along with it came the memories of the shadow clone from this period.
Seimei quickly read through the memories and, finding no problems, once again performed the Shadow Clone Technique, creating a new shadow clone.
Without his command, this shadow clone left the cave space and headed directly to the team's base.
From now on, it would replace him and stay there.
With everything ready, Seimei didn't waste any time and turned to enter the depths of the cave to complete his first harvest.
But after taking just two steps, he seemed to remember something and suddenly muttered, "Panel!"
The next moment, the familiar light blue screen appeared.

Skipping the previous sections, Seimei focused his attention on the 'Chakra Absorption Technique'.
As he remembered, after nearly ten days of practice, its proficiency had reached lv2 (435/500), only sixty-five points away from lv3.
Considering the massive amount of chakra he would be harvesting next, every increase in conversion rate could yield a significant amount of extra chakra.
Therefore, Seimei decided to invest some chakra first to upgrade this technique to lv3.
Thinking this, Seimei didn't waste any time and turned to return to the room his shadow clone had prepared for him, starting to cultivate on his own.
An hour passed in the blink of an eye.
After completing the 'Chakra Absorption Technique' once again, a new insight suddenly dawned on Seimei.
A moment later, Seimei opened his eyes, a flash of understanding in them.
He glanced at the panel, and as expected, his 'Chakra Absorption Technique' had been upgraded from lv2 (435/500) to lv3 (1/1000)!
"I wonder how effective it is?"
Mumbling to himself, Seimei stood up and left the room, heading to the depths of the cave.
At this time, it was no longer just Chiya alone.
Besides him, there were six others: Safo and his three Chunin subordinates, as well as two unlucky individuals who had been left behind when Suna retreated.
Facing these gazes filled with hatred, fear, or curiosity, Seimei walked directly to Chiya's side.
Then, under the cannibalistic gaze of Safo's puppeteer subordinate, he completed the hand seals for the 'Chakra Absorption Technique' and placed his hand on Chiya's head.
A suction force emanated from his palm, rapidly extracting the chakra from Chiya's body.
After carefully sensing for a moment, Seimei had estimated the effect of the lv3 'Chakra Absorption Technique'.
It could absorb approximately three hundred chakra points per second, an improvement compared to the two hundred points of lv2, but not a qualitative leap.
However, the conversion rate had once again increased by ten percentage points, from the previous 60% to the current 70%.
Not to mention anything else, just this 10% increase alone made the consumption of his nearly fifteen hundred chakra points worthwhile.
Seimei even had an urge to upgrade this technique by another level to further enhance its effects.
However, when he saw the one thousand proficiency points required, he calmed down.
Based on the previous calculation of needing fifteen hundred chakra points to increase proficiency by sixty-five points, one thousand proficiency points would require twenty-three thousand chakra points.
This was indeed not a small number.
But at the same time, it wasn't an unattainable goal either.
In fact, it could be said to be very easy to achieve.
Thinking this, Seimei turned his gaze to the other six Suna shinobi, three tomoe slowly rotating in his crimson pupils.
A moment later, he withdrew his gaze.
According to his estimation, the chakra of these people combined was about twenty-eight thousand points, plus Chiya's five thousand, that was thirty-three thousand points.
So, with a 70% conversion rate, that was twenty-three thousand one hundred points, just enough for him to upgrade the 'Chakra Absorption Technique' from lv3 to lv4.
Of course, there would definitely be some errors in this.
However, with his current chakra reserves, he had enough to compensate for any slight errors.
The only thing to consider was that doing so would delay the evolution of his Sharingan and his mastery of the Fire Release's Shape and Nature Transformations.
After all, he had originally planned to use this chakra for practicing the 'Mind Reflection Technique' and the 'Fire Release: Phoenix Sage Fire Technique'.
If he diverted it, it would inevitably slow down their progress.
However, as the saying goes, sharpening the axe won't delay the chopping of firewood. Nᴇw ɴovel chaptᴇrs are published on novel·fiɾe·net
If he could upgrade the 'Chakra Absorption Technique' from lv3 to lv4, based on previous experience, its chakra conversion rate was very likely to improve further.
In that case, the chakra he harvested in the future would definitely increase, more than making up for today's losses.
Moreover, if he only diverted twenty-three thousand chakra points, it wouldn't cause much delay.
With this thought, Seimei no longer hesitated and immediately went to Safo's side.
He once again performed the 'Chakra Absorption Technique', absorbing all the chakra that Safo had managed to recover into his own body.
Instantly, the chakra within Seimei surged to over eleven thousand points, almost reaching the limit his chakra pathways could handle.
Enduring the discomfort in his body, Seimei tore off the tape covering Chiya's and Safo's faces.
Before they could speak, he stuffed a few soldier pills into their mouths and quickly reapplied the tape.
After doing this, he immediately returned to the room his shadow clone had prepared and once again started grinding the proficiency of the 'Chakra Absorption Technique'.
Two hours later, his 'Chakra Absorption Technique' reached lv3 (350/1000), and the chakra within his body decreased to the warning line of four thousand points.
After a short rest, Seimei reappeared in the depths of the cave.
This time, without anywaste, he captured the three Suna Chunin and drained their chakra.
Consequently, his chakra once again recovered to a near-full state.
After routinely feeding them a few soldier pills, Seimei returned to the room and continued to grind the proficiency of the 'Chakra Absorption Technique'.
In this way, after spending a total of six hours and draining the chakra of all seven Suna shinobi, he finally reached lv4 (1/2000) for the 'Chakra Absorption Technique' in the late hours of the night!
Ignoring testing its effects, Seimei practically collapsed into sleep.
Repeating the same action a thousand times, even with strong positive feedback, Seimei couldn't hold on any longer.
Soon, snoring sounds filled the room.
