im not sure if im allowed to post now but i rounded the 100km/s
since im new to this ill jsut have to explain wat i mean
zet refers to the move that creater of this thread makes.

he says that the rocks will move 98 km/s which is basically 100 km/s but a yea im pretty sure u cant see a rock moving 100 km/s either
100miles/hour is a diff story were talking 100km/s

Yeah that's the main problem with this idea, 98km/s = 98000m/s.
The speed of sound is normally 340m/s.
So, 98000/340 is approximately 29
A speed of mach 28 is insane.
It would exceed the speed of anything that have ever traveled near the surface of the Earth.

And then there's the little problem of the grotesquely huge sonic boom that would be created, which I assume would destroy the user.

This is obviously impossible effect occurs because the math behind this jutsu is wrong:

Ishiuchi no jutsu (rock shooting techniuqe) - relys on theories from tree climbing and water walking. In tree climbing, the user concentrates chakra to their feet, and it flows into the tree. The chakra has a naturally compelling nature to itself, resulting in a situation where the chakra in the tree and in your foot is pulling each other together. This is from the fact that when Sasuke used too much chakra, the bark in the trees were pulling at each other with too much force, and fell out. Water walking relies on exerting chakra from your feet into the water, such that it is by nature, pushing away from each other. This results in the user being pushed up from the water, and if done with an equal force to gravity, the user will refrain from sinking into the water, or being thrown into the air. Now, taking these two theories, say a shinobi collects rocks at around 5 gram weight. For using the jutsu, he simply puts a rock on a finger, and exels charka from that finger so that the rock is drawn in. Next the shinobi raises his finger and aims. Lastly, shinobi uses chakra similar to water training to shoot the rock away. Since the feet are the hardest part to concentrate chakra, it should be easy to concentrate at least as much on the finger as in water walking.
Now, lets find how useful this jutsu is. Assuming the shinobi is 50kg, (bit underweight for 15 - naruto's age-), the shinobi is 10,000 times as heavy as the rock. Now, every second, the shinobi must put out as much chakra, as is needed to lift him 9.8 meters, if gravity is lost, since gravity pulls at 9.8m/sec. So, if the shinobi puts out as much chakra in this technique as he uses in the water training per second, he could lauch a stone his weight at 9.8m/sec. Since the stone is 1/10,000 of his weight, we can multiply the speed by 10,000. We have a uses so little chakra, Academy Students could do it, except for the chakra control, and sends a rock flying at 98km/sec. This could probably cut through almost any "ultimate defense". Now, this rock would fly straight through the enemy. Just put some poison on it, such as the near instant kill Kankurou uses, and kill before enemy knows what happened. Sharingan won't help you dodging, since as Lee said, "if you can read the movements, your body doesn't have the speed". So, no matter how good the sharingan, there is no way someone could dodge this at close range.
Several things about this is wrong, the smallest mistake would be the weight of the rock, 5g is almost nothing something that weighs that much would normally not be considered a rock.

But the primary problem with this idea is the 9.8m/s.
What gravity does is cause an acceleration of 9.8m/(s*s) or meters per second squared.
This means that for a 98km/s movement to occur on a 5g rock the rock must be in contact with the user's finger for exactly 1 second.
This doesn't seem like a long period of time but in execution it would be impossible, because the finger would already be accelerating the rock (causing the rock to lose contact with the finger) meaning no further acceleration can occur unless the user moves his or her finger to keep in contact with the rock. There's a exponential increase in the speed that the finger (and the rock) must move in 1 second but by the end of the 1 second the user must also be moving at 98km/s (causing obvious difficulties in the execution of this jutsu).

I don't think Genjutsu is Useless at all. You stated that only Itachi's Tsukiyomi is a good Genjutsu. What about itachi's regular Genjutsu that he cast on Naruto with only his fingers, he had Sasuke coming out naruto's head and Naruto was screaming and crying like a little b****, CHiyo and Sakura had to come and touch for him to get out of it, he couldn't get out of it even while knowing how to dispel a genjutsu. that's how strong Itachi's regular genjutsu(no Tsukiyomi) was.

Also, a jutsu's strength is based solely on its rank. The flashiest jutsu could be the weakest and the ugliest jutsus could be the strongest.

No I mean where are you getting the per second from? If your talking about zets post he didnt say per second.

If you mean the starting post I didnt read it, it was too boreing, since who cares if the jutsus dont make sense or arent worth using, its a shonen manga, they always do stuff like that.

You know i would actually try to follow your math , if u hadnt said that 98 km = 980000..

everything beyond this becomes useless cause a k is 1000 , three 0s not 4. u dont deserve to explain sth with math ... srry

The speed of sound is normally 340m/s.
So, 980000/340 is approximately 288
A speed of mach 288 is insane.
It would exceed the speed of anything that have ever traveled near the surface of the Earth.

Mach 29 is still impossible.

Thanks by the way, I'll edit it. (I started with the 100km/s but changed it to 98 and forgot to remove a 0).

As far as lees speed is concerned , i thought when kakashi taught sauske the chidori , he said it was the fastest speed human body can achieve without side effects, so , whats with faster speeds comming thru , lee can only get faster than that. i.e faster then sound bu opening gates. now we hear all this bs about sauske gaining new speed !

edit: btw ok i can read it now that its been edited !~

You cant use the manga as a point of referance, since nothing is constant in the manga.
