Andrew Grant was truly a remarkable figure, a rare bright spot in the otherwise dim history of the Yuan Dynasty!

He was a native of Hebei, coming from a scholarly family, and was intelligent and eager to learn from a young age. Andrew Grant's studies were not limited to Confucian classics; he was proficient in astronomy, mathematics, and even understood hydraulic engineering.

At the age of twenty, he personally directed the dredging of his hometown’s river channels and repaired a stone bridge that had been submerged for years. From then on, he was unstoppable... building canals and dams everywhere, irrigating farmland.

Later, Andrew Grant joined the Ministry of Works and participated in revising the new calendar.

Andrew Grant thrived in this environment. He invented and improved more than a dozen astronomical instruments, such as the simplified armillary sphere, gnomon, polar sighting instrument, celestial globe, quadrant, equatorial armillary sphere, shadow scale, and sighting tube. He also established twenty-seven observation stations across the country, conducting large-scale “Four Seas Measurements.”

He completed fourteen astronomical and calendrical works, including “Tuibu,” “Licheng,” “Liyi Draft,” “Yixiang Fashi,” “Upper, Middle, and Lower Calendar Annotations,” and “Xiuli Yuanliu,” totaling 105 volumes—truly a prolific author!

But his most acclaimed achievement was the “Shoushi Calendar,” whose accuracy was astonishing, differing little from the Gregorian calendar used in later generations!

Without a doubt, Andrew Grant was an outstanding astronomer, hydraulic engineer, practical expert, and scientist! His accomplishments could be compared to those of Shen Kuo, far surpassing those poets and officials who only dabbled in literary pursuits.

Although Andrew Grant served the declining Yuan Dynasty, he was very fortunate—not only did he rise to the position of prime minister, but he also lived to the age of 86, enjoying both longevity and prosperity.

However, just over thirty years after Andrew Grant's death, peasant uprisings erupted everywhere, eventually overthrowing the Yuan Dynasty to which he had devoted his life.

Andrew Grant's descendants also disappeared amidst the chaos of war, and most of his works were lost. The few surviving manuscripts were so advanced that no one could understand them.

After seeing the canal built by Andrew Grant, Theodore Roosevelt was deeply moved. How could such a genius have been born in the Yuan Dynasty? If only he had been born a hundred years later to serve the Ming Dynasty—how wonderful that would have been!

But wishful thinking aside, the chaos at the end of the Yuan had already destroyed everything, and Theodore Roosevelt no longer dared to hope.

Who could have imagined that, out of nowhere, a descendant of Andrew Grant would suddenly appear!

Theodore Roosevelt's excitement was understandable!

No wonder he knew the art of body refinement—Andrew Grant lived to 86, strong and healthy; how could he not have some special skills? As for astronomy and mathematics, those were the Guo family’s specialties!

“Master Arthur King, do you think this young man can be trusted?”

The old monk laughed heartily, “Your Highness, whether he can be trusted or not, what does it matter? I spoke with him all afternoon and gained much. For someone so young to be so proficient in mathematics—other than being a descendant of the Guo family, I really can’t think of any other possibility!”

Arthur King was very pleased as he smiled. He was well-versed in Confucianism, Buddhism, and Daoism, and also understood astronomy, but he was no match for Andrew Grant. The old monk cared about the “Shoushi Calendar” and astronomy, but he had a deeper motive... The emperor is revered as the Son of Heaven; who can become emperor depends on the Mandate of Heaven, and after becoming emperor, one must remain in awe of celestial omens!

It could be said that the sanctity of imperial power was always tied to the mysterious will of Heaven.

For a hundred years, the one who best understood the “Heavenly Mandate” was Andrew Grant!

If one could master the Guo family’s knowledge, one could manipulate the Mandate of Heaven at will! After all, according to the “Shoushi Calendar,” it was possible to predict solar eclipses!

Arthur King's interest in the Guo family’s descendant was far greater than Theodore Roosevelt's!

If Brian Clark were here, he would surely spit in the old monk’s face!

Damn it, Andrew Grant's astronomy was about exploring the truth, but this old monk was using it to promote superstitions about the Mandate of Heaven—completely missing the point and insulting astronomy itself. It would be enough to make Andrew Grant roll over in his grave!

Arthur King didn’t care about that. After arriving in Beiping, he focused on one thing—constantly urging Theodore Roosevelt to seize the throne!

“Your Highness, now that Heaven has sent a genius to assist you, it proves you are the destined one. This humble monk dares to suggest...”

“Shut up!”

Theodore Roosevelt's eyes were bloodshot, looking terrifying!

“Master Arthur King, do you think my sword cannot kill?” Theodore Roosevelt leaned forward, unconsciously gripping his sword hilt, as if he might draw it and kill at any moment, blood splattering in all directions!

But the old monk just smiled calmly, “If Your Highness wishes to take this old monk’s worthless life, just do it. Even if I die, I will remind you in your dreams!”

Damn, is this the legendary ghost that won’t leave you alone?

Theodore Roosevelt was truly speechless.

Stuck with such a stubborn and persistent character, he had no better solution.

“Master, I, Theodore Roosevelt, have no grudge against you. Why do you insist on harming me?”

Arthur King replied solemnly, “The throne should be held by the virtuous. Your Highness is the son of a sage—why shouldn’t you seize it?”

Theodore Roosevelt smiled bitterly in his heart, “Master, I beg you, please never mention this again. What my father has decided, no one can change. If you insist on such nonsense, I will have no choice but to be rude!”

Originally, after meeting the Guo family’s descendant, Theodore Roosevelt was in a good mood, but Arthur King’s meddling immediately dampened his spirits... To be honest, what prince hasn’t dreamed of becoming emperor?

The problem is, George Washington is a stubborn old farmer. He treats the empire as his own farmland, punishing corrupt officials as naturally as pulling weeds.
