If it was someone else, at least a fierce tiger would not eat their young, but normal logic could not be used to deduce Jia Lai Ying Huo. He truly could commit such a thing as using his son's own life to trick the enemy into opening the gate.

At Shen Yi's command, the Black Iron Camp immediately drew up its swords and arrows. The killing intent on the northern ground greatly increased, surrounding the envoys.

The Second Prince trembled on his horse's back, seemingly about to fall off, a team of trained Ziliujin inspectors ran out, opening the chests and checking in front of the Man envoys.

Several carts of Ziliujin, which made people drool, were thus exposed to Shen Yi and others.

The Ziliujin inspector dared not be careless. He inspected the purity of Ziliujin in each cart one by one, and put the characteristic pole into the sealed carriage to check the volume.

Several long poles stained with Ziliujin were presented to Shen Yi. The scale on them was almost full. The inspector quickly reported, "General, purity is of no problem, reaching the proper level for tribute."

Shen Yi made an ‘Mm’ sound, still did not put aside his doubt, then looked up at the Second Prince. On his forehead, there was an angry purple mark, appearing as if it was created by a whip. The prince’s face was wet with tears and snot, opening his mouth as if wanting to cry out but he could not make a sound.

Chen Qing Xu whispered, "General Shen, you see, there is a purple mark on his forehead. I have heard about it in the Eighteen Tribes. It is a witchcraft poison for extinguishing one's ability to speak. His entire body is stiff now, which is equivalent to being fixed on the horse. He will not even be able to let out a cough. In a few moments, when the purple mark darkens, he will fall to the ground and die. Even if doing an autopsy, he will only be found to have been overly frightened and died of fear and palpitations."

Without blushing or shying away, Shen Yi shouted, "Wait, stop them!"

The Eagle in the sky gave a sharp cry: "Stop!"

The horse of the Second Prince stopped suddenly, his whole body leaned forward as if his center of gravity was unstable. His hard boots hit the top corner of the nearby oil tank, making a lingering noise of an echo.

One corner of the tank was empty!

Shen Yi's pupils suddenly shrank: "Fall back!"

As he finished, a man in the group of envoys rushed to an oil tanker and was shot dead by an Eagle with quick eyes. The whole Black Iron Camp silently fell back at the fastest speed. Shen Yi pulled Chen Qing Xu's horse rein, urging it to move back.

A cluster of sparks erupted into the sky.
