Chapter 4: Awakening Sharingan.

Fugaku was in his own world but seeing the Iwa shinobi coming toward himself he immediately fires off Fire style: Fireball at the Iwa shinobi and sees that the other shinobi is headed toward his son, he activates his Sharingan and puts the Iwa shinobi with burn marks into genjustu, but the genjustu was not strong enough as it was cast in hurry just to slow down the shinobi, the jounin with the burn marks was easily able to distinguish that he is fallen for genjustu and he distrubs his chakra to get out of genjustu, Itachi just needed a small slip of time to deal with the jounin, seeing the chance Itachi immediately arrives in front of jounin with burn marks by taking big and strong leaps, as soon as Itachi arrives in front of the Iwa shinobi, he had broken himself out of the genjustu and he sees that in front of him his prey has just walked over itself to get fed by the Wolf and he grins, he immediately takes out kunai from his holster of kunai and shuriken, he plunges the kunai directly to forehead of Itachi, but Itachi side steps and avoids the kunai by single hair distance and gets even closer to the shinobi as with his 4 years old body his reach is very short compared to the adult so to land a proper blow, Itachi gets closer to the shinobi by risking his life on the edge of kunai by barely dodging it by single hair distance so that he does not have to waste more energy as his 4-year-old body is not suitable for combat having less reach and low stamina, so he immediately moves front whenever he gets the chance but the jounin knew what Itachi is trying to achieve, even then he allowed Itachi to come closely inside his attacking range because he was confident that he can easily kill the child in front of him in less than 2 minutes, so he wanted to know what is going to happen even if he lands a punch, a single punch from childd would only amount to tickle so there is need to cautious of it but instead the moment he punches it will give the juonin perfect chance to counter attack Itachi and kill him, just as Itachi and juonin wanted Itachi came really close to the jounin to the range of attacking and Itachi punches, with nothing special in it, it seems just like a normal punch to all the observers but in that punch Itachi had put 10% If his total power, as Itachi had gotten the wish of Saitama's power but he had not gotten all the power at once the power is getting adjusted to his growing body just like how he grows more on time the power is also acclumating inside his body, by now he has acquired around 40% of the Saitamai's power the remaining power would eventually come with the onflow of time.
