Naruto: They Have Systems: Chapter 105

After the crowd observing Training Ground No. 6 behind Konoha dispersed, Hiruzen Sarutobi went there himself.

The site of Training Ground No. 6 was unrecognizable. All that remained was a small basin where not a blade of grass grew.

Kushina and Mikoto waved, bidding each other a "reluctant"
