A quarter of an hour later. The two shadow clones practicing the Rasengan were the first to fail and turned into a ball of chakra, carrying experience and memory, and returned to the original body. Qingming, who was practicing the 'Reflection Heart Technique', frowned, and then separated a part of his mind and began to integrate these experiences and memories. After a moment, he opened his eyes, opened the panel and glanced at it, and saw that the proficiency of the 'Rasengan' had increased by thirty points. And with the same chakra, if the original body was allowed to practice it personally, it could gain about forty-five points of proficiency. In other words, the efficiency of the shadow clone's practice is only two-thirds of that of the original body. And this is still the efficiency in a short period of time. If it continues, and the shadow clone is not refreshed, this efficiency will be further reduced until it encounters a bottleneck and the efficiency drops to zero. However, Qingming will definitely not let this happen. Glancing at the two shadow clones who were still practicing the 'Illusion·Sharingan', Qingming thought about it and took the initiative to cancel the 'Shadow Clone Technique'.
Then, two more experiences and memories returned, and Qingming savored them carefully. After integrating all these experiences and memories, he opened the panel and took a glance. He saw that the proficiency of the 'Genjutsu·Sharingan' on it had increased by 50 points, and the efficiency was about two-thirds of the main body. Qingming nodded with satisfaction, then came to the side of a rock ninja, performed the 'Chakra Absorption Technique', absorbed the opponent's chakra, and replenished the chakra in his body. Then, he performed the 'Shadow Clone Technique' again, split out four shadow clones, and began a new round of training. In this way, every fifteen minutes or so, Qingming would refresh the status of the four shadow clones and replenish chakra by the way, and repeat the cycle. Soon, the time came to an hour and a half later. After Qingming once again integrated the practice experience of the two shadow clones about the 'Rasengan', his 'Rasengan' proficiency directly reached lv1 (197/200)! Considering the possible bottleneck, Qingming simply stopped practicing the "Reflection Heart Technique" and practiced the "Rasengan" three times himself. So, without any surprise, his "Rasengan" directly entered the level 2. As a result, Qingming's understanding of the "Rasengan" also rose to a higher level. At this time, when he cast this technique again, both the speed and the condensed chakra ball were much stronger than before. However, if he wants to reach the point where he can integrate the wind escape chakra and then develop the S-level ninjutsu - Wind escape Rasenshuriken, there is still a long way to go. Qingming is not too anxious about this. Anyway, he has not fully mastered the changes in the form and nature of the wind attribute chakra. Even if he raises the level of the "Rasengan" now, it is difficult to complete the step of integrating the wind escape chakra. So. "Let's do it step by step!" Muttering, Qingming sorted out his mood and cast the "Shadow Clone Technique" again, splitting out four shadow clones and continuing the practice just now. ······
Time passed by minute by minute. In the blink of an eye, more than an hour had passed. As the three-hour deadline was about to arrive, Qingming finally achieved his goal. Of the total 200,000 chakra points, 28,000 points were used by him to practice the ‘Reflection Heart Technique’, gaining 180 points of proficiency. 150,000 points were used on the ‘Rasengan’ and the ‘Genjutsu·Sharingan’, increasing their proficiency by 360 points and 600 points respectively. Another 20,000 chakra points were lost due to the frequent use of the ‘Shadow Clone Technique’. To be honest, Qingming felt really painful when he saw these losses, but there was no other way. He could only do this in order to save time. Qingming stood up, glanced at the bodies of the Rock Ninjas on the ground, then formed a seal and performed the ‘Fire Style·Great Fireball Technique’. Boom~ The red flames spread and covered all the bodies in the blink of an eye. A smell of burnt flesh and blood came, Qingming frowned, covered his nose and took two steps back, and left the place after all the bodies were burnt. Shortly after he left, more than a dozen rock ninjas escorted two medical ninjas here. Obviously, they were the rock ninjas responsible for receiving the wounded. However, what awaited them was only the burnt corpses on the ground. Immediately, all the rock ninjas changed their faces. Some looked around vigilantly, some contacted their superiors to report what happened here, or searched for the enemy's traces. In short, they were busy and happy. When they found some clues, Qingming had already found the second target. This was a team of four people, who were in a hurry at this time, and didn't know where to go? Qingming carefully followed for a distance, and after confirming that there were no other people around and that the four were only Chunin, he decisively took action. Almost without much effort, all four were knocked down by him. Afterwards, Qingming directly used the ‘Genjutsu Sharingan’ to guide the leading Iwagakure Chunin to recall the relevant information of this mission. Soon, he figured out the mission of these four people. It turned out that they were here to pass on a piece of information. As for the content of the information. Qingming ripped open the man’s clothes and took out a scroll from his arms, but after seeing the seal spell on it, he gave up the idea of checking it. For information like this, there must be a corresponding solution to open it, otherwise the scroll will self-destruct. Obviously, these four tools could not know the correct solution.
So, Qingming did not waste this time. After scanning the surrounding environment, Qingming performed the "Shadow Clone Technique", split a shadow clone, and then left the place with two of them and four Iwagakure Chunin. After randomly finding a remote corner, Qingming ordered the shadow clone to be on guard, and he began to prepare for practice. According to previous experience, if he squeezed them with all his strength, these four Iwagakure Chunin could probably provide him with about 30,000 points of chakra. This time he didn't have to rush, he could use all these chakras for the practice of the "Reflection Heart Technique". In this way, he could gain more than 180 points of proficiency. In fact, if he wanted to accumulate proficiency with the highest efficiency, he should find a place to practice by himself, just like a few days ago. Then let the shadow clone go out to capture prisoners, and by the way, use a slow and steady way to harvest their chakra. Only in this way can the value of these prisoners be fully utilized. At the same time, it won't waste too much time. But in the current situation, it is too dangerous to stay in one place, so he can only give up this method temporarily. Fortunately, this time, the Hidden Rock Village mobilized more than 10,000 ninjas to encircle the Third Raikage and the elite Cloud Ninjas led by him. And so many ninjas gathered together, even if they are well-trained, they will inevitably cause some confusion. In this way, he can easily find the target to attack, and will not waste too much time. Shaking his head, putting these miscellaneous thoughts behind his mind, Qingming calmed down and began to seriously comprehend the whole process of the "Reflection of the Heart Technique" taking effect.
