Tobirama Senju had prepaid him with one of his secret techniques: Chakra Sensing.
Kawadera Uchiha crouched on the ground and tapped the earth with his fingers.
Chakra flowed through his fingers in a special rhythm, turning them into something like a tamping machine. Waves of chakra hammered against the ground like mallets.
Very quickly, he used chakra to probe the resonance frequency of the nearby earth.
Once it entered the ground, the chakra rapidly spread outward from his fingers in all directions.
According to Tobirama Senju's memories and insights, chakra traveled through the earth at six hundred meters per second.
Whenever the circular chakra waves encountered any person or object with chakra, they would be depleted.
After reaching the limit of its sensing range, the chakra would return to his fingers in circular waves.
Once mastered, one could determine an enemy's location, distance, and even chakra strength based on the returning chakra.
For moving enemies, one could release chakra sensing several times to calculate their speed.

"One, two, three, four... There are four people running for their lives. Three humans and one dog. Good, no casualties yet."
Kawadera Uchiha hurried after them.

Just as he turned back again, he saw a pair of scarlet eyes flash through the dim forest.
Not good!
I may have fallen under a genjutsu!
He carefully examined everything before him, but nothing seemed unusual.
The Mist ninja squad leader let out a breath. Perhaps that Uchiha was a ninjutsu-type
