Chen Feng had never had the authority to modify his ninjutsu. However, he had already seen the effect of the Ninjutsu Modification Authority. It could increase the power of the most ordinary C-grade Ninjutsu to a terrifying state.
Now that things had come to this, Chen Feng decided to use his ninjutsu to modify his authority.
Uchiha Tenmu was a Jounin after all, and he knew how to teleport. Even Chidori would find it difficult to kill him in close combat. Chen Feng was confident that he could kill him if he continued to drag this out. However, if he dragged this out for too long, things would change.
"System, I want to exchange for the right to modify ninjutsu!”Chen Feng did not hesitate.
The female voice of the system rang in Chen Feng's ears,""The host can modify any C-grade ninjutsu. After modification, its power will be upgraded to S-grade, and its power will be greatly increased.”
That's right, the system's ability to modify ninjutsu was to directly increase the power of a C-grade ninjutsu to an S-grade ninjutsu!
This was Chen Feng's trump card.
"Grand Fireball Technique!" Chen Feng had already thought about it.
"Congratulations, host. The modification has been completed and the power of the Grand Fireball Art has been increased.”
Chen Feng only used an instant to modify his ninjutsu.
Immediately after, Uchiha Tenmu released three Fire Escape Ninjutsu in a row. The flames surged and rose ferociously, roaring and roaring, and waves of heat.
Chen Feng calmly formed a seal and said,""Fire Escape, Grand Fireball Technique!"
Uchiha Tenmu was stunned for a moment. He was on guard against Chen Feng's powerful ninjutsu, but when he heard Chen Feng's words, he almost burst into tears."Hahaha, you actually used the Grand Fireball Technique. Are you kidding me?”
In all fairness, the Grand Fireball Technique was very useful in C-grade ninjutsu, and its power was also quite good. However, it was clearly far from enough.
But soon, Uchiha Tenmu's laughter suddenly stopped.
His eyes suddenly widened as if he had seen a ghost. He was so scared that his soul almost left his body. A bead of cold sweat the size of a soybean dripped down from his forehead, but he still did not notice it.
Flames soared into the sky!
Chen Feng opened his mouth and spat out a huge fireball. The flames rose, causing the surrounding temperature to double!
This fireball was also ridiculously large, at least ten times larger than an ordinary Grand Fireball!
The huge fireball was much stronger than the combined power of Uchiha Tenmu's three ninjutsu. It made Uchiha Tenmu want to turn around and run, but it was too late.
Boundless fear enveloped Uchiha's Heavenly Eye. His eyes were filled with panic and despair. How was this a powerful fireball technique? This was simply the summoning of the Grim Reaper!
In the next second, the flames devoured everything.
Burn the land.
It turned out that when the flames reached a certain level, there was nothing that could not be burned.
At this moment, the flames seemed to burn everything.
The sky disappeared.
The earth disappeared.
The three Fire Escape Ninjutsu were instantly destroyed.
The Uchiha's Heavenly Eye was also burned to ashes in an instant, not even leaving a corpse behind.
Not a single corpse was left behind as they turned into ashes.
Chen Feng's chakra was also consumed rapidly. Fortunately, he had the body of an immortal, so his chakra capacity was different from ordinary people. That was why he could withstand it.
The [S] class Fire Escape Ninjutsu was indeed very exhausting.
However, it was all worth it. Chen Feng had used this spell to kill a Jounin.
"As expected of a Modifier. The power of this Grand Fireball has actually been raised to such a terrifying level. However, the consumption is also shocking. Fortunately, I have the body of an immortal. Otherwise, whose chakra could withstand such consumption?”Chen Feng shook his head and sighed.
"That's good too. I've completely destroyed the corpse. No matter how the Uchiha family looks for me, it'll be very difficult to trace it back to me. Even if they find out, my strength will not be what they imagined…"
When Chen Feng thought of this, he heaved a sigh of relief.
Uchiha Tenmu was a Jounin after all. His death would definitely attract the attention of the Uchiha clan, and they would definitely track down his whereabouts. However, Uchiha Tenmu had been burned to ashes by the flames, so even the Uchiha clan would have a hard time finding any clues.
Uchiha Tenmu was completely dead. Even his katana had disappeared safely after the high temperature of the flames. The scene was charred black, and the smell was pungent. It was beyond recognition.
Chen Feng was very satisfied with the effect of the ninjutsu.
"Ding! Congratulations to the host for killing Jounin for the first time. You have received a silver treasure chest.”The system's clear voice echoed in his ears.
Chen Feng smiled when he heard the voice.
Very good, I finally got another reward!
However, Chen Feng didn't check the rewards immediately. Instead, he chose to return home first. After all, this place was really not safe, so he didn't want to cause any more trouble.
Chen Feng was even more cautious after this. It seemed that he could not use Sharunaka casually. Once he used it, the enemy would die!
After all, only the dead could keep secrets.
Of course, as long as Chen Feng became stronger and could ignore Uchiha's threat, he would be able to use Shurunyan at will. He was looking forward to that day.
Chen Feng carefully checked the surroundings. After confirming that there were no traces left behind, Chen Feng quickly left.
They hurried back home.
Chen Feng returned home and drank a mouthful of water to calm himself down. Then, he entered the Modifier Space!
In the space of the Modifier, a treasure chest with silver patterns appeared.
The patterns on this treasure chest were exquisite. The patterns on it were complicated and gorgeous. The material seemed to be gold but not gold. It was not ordinary.
"It really is a Silver Treasure Chest, a treasure chest of a higher grade than a Bronze Treasure Chest!”Chen Feng became excited.
"Host, do you wish to open the treasure chest?”
Of course, it was opened. Chen Feng still wanted to see what good things there were!
