At this point, Shangguan Qianyu understood that first, he was not their only choice, because there was also an emperor Fuhan.

Second, if a master who can't carry the banner himself, no matter how much external force he has, he can't support the wall.

The Marquis of Chiayi sighed: "If you are incompetent, brave, ignorant and powerless, we can only let the first prince avenge his grievances forever, and let the eldest princess and the concubine hate Jiuquan." However, while the abilities you have now shown give us hope, we are still not sure if you are the son of the first prince. ”

Shangguan Qianyu said: "This king's master, is it one of the four secrets?"

Chiayihou nodded and smiled, and said: "Exactly, that one who is both civil and military, after teaching you for three years, has already entered the official career like Benhou." If you are the son of the first prince, we are your help. If you are not, we will not hurt you. ”

Shangguan Qianyu glanced at him, if he wasn't, he knew such a secret, shouldn't he be exterminated?

The Marquis of Chiayi seemed to see through what he was thinking, and sighed: "The first prince is benevolent and gracious, Ze is given to the people, everything is done to the people first, virtuous, filial piety and benevolence." Hundreds of thousands of victims in Fengzhou, all of them are alive because of you, Anyang Hou, although you did not remove it, but also you contributed to it, even if you can't determine your identity, but your behavior also made my generation see the shadow of the first prince, only admiration. ”

If a person hears such a thing at first glance, he will be shocked and inexplicable, but what Shangguan Qianyu found out in the past two years has already sorted out a line, and he has hidden guesses in his heart about these, so he is not so shocked, but seems very calm and calm.

At this moment, he said even more calmly: "If my guess is correct, this picture should be the key to finding the jade seal and the edict, provided that I need to prove who I am." You seem to have a way to confirm my identity?"

Murong Xiao nodded and said, "Naturally." At the beginning of the emperor's determination of the prince, he asked a skilled craftsman to make this short sword, when the sword was not completed, the emperor took the prince to watch, but the prince was greedy to play, but the sword was cut by this sword, the blood stained the sword body, the swordsmith's eyes lit up, the sword melted blood and recast, and the prince's blood melted into the sword body. The swordsmith said at the time, this sword will be fulfilled, and the coincidence will be completed, if the father and son are close to each other, dripping blood on the sword body, and the sword body will suck it, it is for the father and son, and the sword body will abandon it for others. Therefore, the name of this sword is Pulse Yin, which is inherited in the same vein, but it is hidden and not revealed!"

"Then can't brothers and nephews either?" Such a magical thing, even Leng Tengfei couldn't help but ask.

Murong Xiao shook his head and said, "The first emperor also didn't believe it, took his own blood and dripped it on the sword body, and the sword body sucked it. Take the blood of the second prince, the sword body will not suck, the second prince and the prince are the same brothers, not to mention others? Therefore, when the prince was in trouble, the emperor sent away the prince's son-in-law and sent this sword to confirm the identity of the prince's son. ”

If Shangguan Qianyu is the son of the eldest princess Huangfu Ling'er, the sword body will not suck his blood, and if Shangguan Qianyu is the son of the first prince, it will be recognized by Mai Yin.

The three of them looked at Shangguan Qianyu with eager hope, and the meaning was very clear, that is, they hoped that he could take a blood test.

Shangguan Qianyu also had such doubts in his heart, he stretched out his right hand, and the nail scratched the tip of the index finger of his left hand, and suddenly the skin broke and blood flowed, and a drop of red blood dripped down the sword body.
