When the Wood Release Experiment had just been completed, Shimura Danzō had hesitated over whether to inject himself with Hashirama Senju's Cells.
After all, the Wood Release wielded by those Wood Release Experiment Subjects did not seem particularly strong.
Shimura Danzō wanted Hashirama Senju's Wood Release, not some Dead Last version of it.
But his subordinates assured him that he could start with this weaker version of Wood Release Cells. It would still increase his strength, physical resilience, and Chakra reserves. Once his body had adapted, he could transplant more potent Hashirama Senju's Cells. The more Shimura Danzō thought about it, the more sense it made.
So, without anyone else knowing, Shimura Danzō transplanted a specially prepared version of Hashirama Senju's Cells into himself. The results were excellent. He could clearly feel that his Chakra had at least tripled, his body had grown far more vigorous, and his Ninjutsu had become considerably stronger.
At Shimura Danzō's age and level of strength, making any further progress was already extraordinarily difficult.
If he could inject himself with stronger Hashirama Senju's Cells, he would undoubtedly grow stronger still. The thought of one day reaching Hashirama Senju's level sent excitement surging through him.
All he had to do was deal with Hiruzen Sarutobi and Uchiha Yi, and the Hokage's seat would be his. With the Impure World Reincarnation Jutsu and strength to rival Hashirama Senju's in the future, Shimura Danzō was confident he could bring the entire Shinobi World to heel.

Once he controlled Konoha and became its Fourth Hokage, he would wage war on the other villages. Kirigakure, Sunagakure, Iwagakure, and Kumogakure—all of them would die.
He would surpass Hashirama Senju and become the
