So, Ōnoki created the rock shield he had already prepared.
He infused more Chakra into the rock shield, making it larger and sturdier.
The Wind Ball collided with the rock shield and exploded.
The fierce wind eroded the surface of the shield but couldn't penetrate it.
When Feng Zheng saw the rock shield emerge from the ground, he had already prepared two larger Wind Balls and Body Flicker Technique to a better shooting position.
Before the rock shield was even fully erected, he was already close to the Shadow Clone, only about ten meters away.
Due to the rock shield, the Shadow Clone didn't see Feng Zheng Body Flicker Technique next to him.
But when he saw Feng Zheng so close, he launched several Shuriken at Feng Zheng.
Feng Zheng saw two Shuriken flying towards him and thought.
"Tch... I don't want to take them head-on."
So he launched a Wind Ball to neutralize the Shuriken and fired a second Wind Ball at the Shadow Clone.
However, the Shadow Clone Body Flicker Technique away, and Feng Zheng pursued him.
For the next minute, they Body Flicker Technique at extremely high speeds, trying to attack each other with Wind Blast Technique, Shuriken, or kunai.
However, neither side succeeded.
Soon, the Shadow Clone found an opportunity, surrounded Feng Zheng with six Shuriken, and launched several Wind Blast Technique in the only direction he could escape. Feng Zheng thought.
"It's over, a normal escape would be dangerous. I'll go underground then."
Then he used Earth Army Movement Technique to go underground.
However, recalling the Shadow Clone's previous predicament, he didn't close the distance. Instead, he constantly sensed the Shadow Clone and the Wind Ball in the opposite direction.
He thought.
"Hmm, I need to distract him now to get out of the ground."
He prepared the Great Breakthrough Technique.
As soon as his head emerged from the ground, he saw the Shadow Clone launch two Wind Balls at him, while also manipulating six Shuriken.
However, Feng Zheng used the Great Breakthrough Technique to nullify all these attacks.
The Shadow Clone himself was within the impact range and escaped underground.
Feng Zheng tracked his Shadow Clone, thinking.
"I guess he'll do something similar to what I did. I wonder if I can interfere with his movement underground."
Then, he arrived directly above where the Shadow Clone was and punched the ground hard with his Chakra-infused fist.
The ground cracked slightly, and the Shadow Clone underground felt the tremor from the punch, but it caused no damage.
Feng Zheng thought.
"Damn it, this is useless! Sigh, it seems I'm still far from Tsunade's level."
Then he Body Flicker Technique to a nearby tree, prepared two Wind Blast Technique, and also got ready to Body Flicker Technique.
As he waited for his Shadow Clone to surface, he thought.
"I really need to learn a way to force people out of the ground. I can think of the Ninjutsu Ōnoki's son used, and maybe flooding the ground with water to restrict air circulation."
On the other hand, the Shadow Clone was also planning, thinking.
"That was too close! If my main body were stronger, that punch just now would have dispersed me. What should I do now? I can feel that my main body has prepared the Wind Blast Technique and is waiting for me to emerge. I don't think the rock shield will work very well this time."
While he was still observing, he felt something and thought in confusion.
"Wait, I can breathe? So that's it, the ground cracks caused by that punch allowed some air to seep in. This is very disadvantageous for the main body."
"Also, I never thought that Shadow Clones would also need to breathe, which is quite surprising. I wonder if Tobirama could create a Shadow Clone Technique that doesn't require breathing, or if he added this ability to Shadow Clones just to increase his efficiency in infiltration missions."
"If it's the latter, then I need to find a way to eliminate the Shadow Clone's breathing requirement. That way, the Shadow Clone can stay underground for hours!"
"Anyway, I don't have time pressure now, so I'll just wait here until I can come up with a good idea. After all, I don't have any good ways to deal with the main body for someone hiding underground."
Meanwhile, Feng Zheng kept waiting on the tree branch for the Shadow Clone to surface. After waiting for five minutes, he thought.
"Does the Shadow Clone not need to breathe? Surely these cracks can provide air all the way down, right? Sigh, I really can't do anything. Only Mud Swamp Technique has a chance, but its range is too small to be effective. I wonder if my Shadow Clone has some strategy, or if he's just wasting time."
He continued to sense the Shadow Clone for another five minutes, finally couldn't stand it anymore, and dispersed the Shadow Clone.
After receiving the Shadow Clone's memories, he exclaimed about the Shadow Clone's patient waiting underground.
"Sigh, this is my Shadow Clone. I remember playing a game called 'Counter-Strike' in my previous life. My team and the enemy attacked each other, and within 5 minutes, all my teammates died, leaving 2 enemies alive. They thought they had won, but then realized they still had one more to kill. The poor guys tried to find me for five straight minutes! Finally, when they entered the cave where I was hiding, I successfully killed them!"
Feng Zheng began to analyze his sparring situation, thinking.
"Hmm, disregarding the ending, this sparring went quite well. However, it was mainly a mid-range battle. Offense used Great Breakthrough Technique and Wind Blast Technique, battlefield control used Projectile Control Technique, defense used Rock Shield Technique, and evasion used Body Flicker Technique and Earth Army Movement Technique."
"Wind Clone is another Ninjutsu that could have been used, but we didn't, as it would have caused confusion. Other Ninjutsu also didn't play a role in this battle."
In fact, Feng Zheng really wanted to close the distance, but his Shadow Clone's strategy was not to fight at close range, because he would be dispersed if he was hit.
So Feng Zheng couldn't use Taijutsu or Kenjutsu, nor did he have a chance to use Wind Push Technique.
With his current technique, it was impossible to cast Genjutsu in such a high-speed battle.
The more concerning aspect was definitely the underground battle.
Against underground enemies, Feng Zheng had no better way than to go underground himself.
But fundamentally, Feng Zheng was not good at underground combat, so this was very disadvantageous for him.
And punching the ground to open it was very foolish, as it would give underground enemies better access to air!
Besides that, Feng Zheng also needed to strengthen his offense.
Feng Zheng thought he could have penetrated the rock shield with a kunai, but he couldn't do it with a wooden kunai. Anyway, his current Ninjutsu couldn't break it.
Additionally, Feng Zheng needed to use Body Flicker Technique more appropriately. Both he and his Shadow Clone sometimes Body Flicker Technique too far. This reset the battle rhythm.
He needed to be able to estimate the correct Body Flicker Technique distance so that he could immediately continue his offense.
Feng Zheng thought this would require a lot of sparring training to master.
