This enemy disposed of, Hoangti had another with whom to deal. At his court resided Prince Tan, heir of the ruler of Yen. Whether out of settled policy or from whim, the emperor insulted this visitor so flagrantly that he fled the court, burning for revenge. As the most direct way of obtaining this, he hired an assassin to murder Hoangti, inducing him to accept the task by promising him the title of "Liberator of the Empire." The plot was nearly successful. Finding it very difficult to obtain an audience with the emperor, Kinkou, the assassin, succeeded in an extraordinary way, by inducing Fanyuki, a proscribed rebel, to commit suicide. In some unexplained way Kinkou made use of this desperate act to obtain the desired audience. Only the alertness of the emperor now saved him from death. His quick eye caught the attempt of the assassin to draw his poniard, and at once, with a sweeping blow of his sabre, he severed his leg from his body, hurling him bleeding and helpless to the floor.
Hoangti's retribution did not end with the death of the assassin. Learning that Prince Tan was the real culprit, he gave orders for the instant invasion of Yen,—a purpose which perhaps he had in view in his insult to the prince. The ruler of that state, to avert the emperor's wrath, sent him the head of Tan, whom he had ordered to execution. But as the army continued to advance, he fled into the wilds of Lea-vu-tung, abandoning his territory to the invader. In the same year the kingdom of Wei was invaded, its capital taken, and its ruler sent to the Chinese capital for execution.
Only one of the great principalities now remained, that of Choo, but it was more formidable than any of those yet assailed. Great preparations and a large army were needed for this enterprise, and the emperor asked his generals how many men would be required for the task of conquest.
"Two hundred thousand will be abundant," said Lisin; "I will promise you the best results with that number of men."
"What have you to say?" asked the emperor of Wang Tsein, his oldest and most experienced commander.
"Six hundred thousand will be needed," said the cautious old general.
These figures, given in history, may safely be credited with an allowance for the exaggeration of the writers.
The emperor approved of Lisin's estimate, and gave him the command, dismissing the older warrior as an over-cautious dotard. The event told a different tale. Lisin was surprised during his march and driven back in utter defeat, losing forty thousand men, as the records say, in the battle and the pursuit. What became of the defeated braggart history fails to state. If he survived the battle, he could hardly have dared to present himself again before his furious master.
Hoangti now sent for the veteran whom he had dismissed as a dotard, and asked him to take command of the troops.
"Six hundred thousand: no less will serve," repeated the old man.
