According to Sakura Hiden Page 158. Sakura can focuse her Chakra throught out her body to create a force feild of sorts to withstand a blow, Simular to how Neji's rotation works, but much more focused and powerful. And she doesn't have to spin, and this was in base form, while fitting Kido, in his 9th tailed form.
Branches snapped soundly left and right as Sakura was thrown into the further depths of the forest. Had she not used her own chakra as a shield around her body to soften the blow, surely she would be down and out of this battle by now.
Her back smashed in to the trunk of a gigantic old tree, and her momentum finally stopped. Sakura let herself slide down the incline of the trunk, but immediately switched her stance for the counterattack.
“You’ve got guts!” Kido rapidly jabbed his tails. Sakura ducked out of the way of the purple spears attacking her, dodging them by a hair’s breadth and finally weaved her way to be directly in front of Kido’s solar plexus….
And punched him, hard.
The outer skin was rock solid. Sakura felt as if the recoil of the attack itself was about to break her own body to bits. However, Sakura could also feel it in her fist that she had landed a solid hit herself.
As a proof of that, large cracks had formed at the point of impact upon Kido’s chest. Small fragments began to break off and fall.
“What terrifying power you have, to be able to even damage me after I consumed the tailed beast drug. However-,” Kido smirked disconcertingly “I can just restore it back to how it was.” The cracks rapidly mended themselves right before Sakura’s eyes, and looked just as it did before.
