Ultimately, Uchiha Gen chose the third exchange route.
That is, to strengthen himself by using bloodlines from outside the Naruto World, while balancing immediate combat power and future growth potential.
"The main weakness of Ninja in the early stages is that they are too fragile; they are squishy until they reach Six Paths level. Therefore, the exchange must focus on improving survivability and concurrently enhancing combat power."
Uchiha Gen pondered in his mind.
Although Ninja possess defensive capabilities that allow them to crash through trees and walls without dying, which is much stronger than ordinary people, this defense is negligible compared to the attack power of similarly ranked strong individuals.
They can easily be overwhelmed by a wave of control and damage, leading to instant death, making their fault tolerance too poor.
If Uchiha Gen only had one or two B-rank side quests, he would have unhesitatingly exchanged for the Troll Bloodline.
A pure Troll Bloodline isn't particularly strong, but as long as a Troll has half its body remaining, it won't die even if its brain or heart are destroyed, and its recovery ability is incredibly astonishing.
For Ninja, stamina is Chakra, and Chakra is stamina.
The two can be converted into each other.
The Troll Bloodline could compensate for Uchiha Gen's current lack of durability. Its formidable recovery power would also allow him to ruthlessly push his body to extract more Chakra, enabling him to unleash stronger combat power in a short period while also fighting more enduringly.
Although Trolls have no subsequent advancement routes, Uchiha Gen could exchange for an S-rank divine bloodline as a superior alternative, which would not only provide powerful combat strength but also accelerate his Gene Lock activation speed.
However, Uchiha Gen currently possesses one A-rank side quest.
Following the principle of not unnecessarily splitting side quest exchanges, Uchiha Gen began to filter through the A-rank one-time bloodlines and A-rank starting enhancement bloodlines on the Main God list.
"A-rank Persona user exchange can significantly increase mental power and activate the nascent form of the Persona ability, which overlaps with the Mangekyo Sharingan's ability to trigger a nascent form of the Soul Light. Excluded."
"B-rank one-time exchanges, Academy City esper development and Stand user activation, are both one-time exchanges that prematurely trigger the Soul Light. The Mangekyo Sharingan's special ocular jutsu also belongs to the nascent Soul Light. I can obtain it by finding a way to activate the Sharingan later, so there's no need to waste reward points specifically on it."
"A-rank demi-human: survival ability is maxed out, can revive even after being killed, but otherwise has no other advantages. Combat power bonus is too weak, almost non-existent."
"A-rank Perfect Blood, from the Underworld world, can perfectly integrate multiple bloodlines. With this, I can return to the Naruto World and upgrade my Uchiha bloodline to an Ōtsutsuki bloodline, and obtain various other Bloodline Limits to enhance my combat power."
"However, this is also a type of growth-trap item. Moreover, divine bloodlines, Saiyan bloodlines, and Superman bloodlines all have similar abilities to integrate lower-tier bloodlines."
"If I exchange for this and return to the Naruto World with my current Chunin-level combat power, it will be very difficult to obtain the materials needed for fusion. And if I don't return to boost my combat power, in the upcoming horror movie worlds, the Main God will teach me a lesson."
"Considering both practicality and immediate combat power, it's a bit useless."
Upon seeing the last option, Uchiha Gen realized that only one A-rank bloodline was most suitable for him.
The Saiyan bloodline.
'Saiyan Gene Mutation Bloodline, rating 111 points, suitable for close-combat oriented horror films. Skill: Giant Ape Transformation, can increase combat power tenfold by transforming into a Giant Ape. Each time severe injury is sustained and recovered from, potential can be stimulated to become stronger.
Because it is a mutated bloodline, the exchanger has no tail weakness and will not lose rationality after transformation. Requires one A-rank horror film side quest and fifteen thousand reward points.'
The Saiyan bloodline here in Main God was the most excellent of its kind in the infinite multiverse.
Although it doesn't provide energy circulation, and the 'Ki' from the Dragon Ball world requires additional exchange, for Uchiha Gen, this was also a benefit as it wouldn't conflict with his existing Chakra.
Secondly, the Saiyan bloodline has strong compatibility and can integrate all lower-tier bloodlines, so it won't conflict with Uchiha Gen's Uchiha bloodline.
Furthermore, the Saiyan bloodline can significantly enhance Uchiha Gen's physical attributes, which will also cause his Chakra to surge, greatly boosting his combat power.
Moreover, after exchanging for the Saiyan bloodline, Uchiha Gen can transform into a Giant Ape when in danger, increasing his combat power tenfold to fight for his life. Coupled with the Sharingan and Gene Lock he expects to activate, it can be said his burst potential is maxed out.
Although the Saiyan bloodline isn't particularly durable, if combat power is strong enough to eliminate the enemy first, then there's no need to consider whether survival ability is strong.
Finally, considering future development prospects, Saiyans also possess the characteristic of gaining increased combat power after recovering from near-death experiences, and subsequently, they can exchange for the S-rank Super Saiyan to further enhance their combat power.
Such an excellent exchange, apart from being a bit expensive, has no other drawbacks.
Of course, this wasn't a flaw of the Saiyan bloodline, but a flaw of Uchiha Gen himself.
He wasn't rich enough yet.
"Enhance Saiyan bloodline."
At this moment, Uchiha Gen presented his request to Main God.
"Enhancing this bloodline requires deducting one A-rank side quest and fifteen thousand reward points from the Reincarnator. It is detected that the Reincarnator already possesses the Uchiha bloodline; enhancing the Saiyan bloodline will have a high probability of producing a beneficial mutation. Proceed with enhancement?"
Main God's voice echoed in Uchiha Gen's mind.
"You said 'beneficial mutation' and you're still asking me?"
Uchiha Gen was speechless.
As he confirmed, the reward points were deducted, and a pillar of light enveloped his body, lifting him into mid-air.
At this moment, a large number of golden light particles danced in the air, continuously merging into Uchiha Gen's body, modifying his bloodline.
A comfortable sensation resonated in Uchiha Gen's mind, causing him to involuntarily fall asleep.
After an unknown period, a voice startled Uchiha Gen awake.
"Wife, come out and look at God!"
At this moment, Zhang Jie roared in astonishment, his excited voice echoing across the Main God Space plaza.
"Is this Main God's bloodline enhancement?"
Zheng Zha, who had just found his Gekko Luo Li, arrived at the Main God Space plaza, intending to ask Main God to confirm if his Gekko Luo Li was truly real.
At this moment, he too stared wide-eyed at Uchiha Gen, who was currently undergoing Main God's enhancement in the sky.
"This is too exaggerated. Will we be like this when we get enhanced?"
Zhan Lan also gaped, gazing at Uchiha Gen undergoing enhancement in the sky, muttering incredulously.
"I wasn't this exaggerated when I enhanced my physical attributes before. It seems A Xian enhanced something incredible."
Zhang Jie explained.
Subsequently, the three saw that the light emitted by Main God had begun to dim, and Uchiha Gen's body slowly descended to the ground.
