Xiao Tianyang could be certain of that answer because of a pattern.
The overall strength of figures summoned by the system depended specifically on three aspects.
First, the system itself.
Simply put, the system would grant them additional opportunities, giving them greater room for future growth.
Take Yue Fei and Bai Qi, for example. They had no need for the system to strengthen them; they could hold up a world on their own.
Then there were people like Nong Yu, Tian Kaijiang, and Jubao, fortunate individuals favored by the system.
Whether it was their current strength or future potential, they had reached the standards of top-tier Outstanding Persons.
Of the three aspects, this was the most critical determining factor.
Second, it depended on their achievements in history.
For example, Yue Fei, Bai Qi, Wang Jian, Li Mu, Han Xin, and Li Jing all possessed exceptionally high War Talent.
The source of their talents lay in their historical accomplishments.
For instance, the Jin people once said of Yue Fei, "Shaking a mountain is easy; shaking the Yue Family Army is hard."
When converted into a War Talent, those words became a talent called Immovable as a Mountain.
Its effect was that when one's own side was being invaded, the overall combat strength of the troops under command increased by 30%, while their morale would never decline.
Or there was Yue Fei's second War Talent, Yue Wumu, whose effect was to rapidly form an army and enhance soldiers' attack power.
Bai Qi's Kill to Stop Killing, Lord Wu'an, and Blood Sea Surging were all exceptionally terrifying War Talents.
