"Qingping, the righteous militia will hand over the arrangements to you, and bring Qin Zixin to me." Xue Lingjing looked at the black and oppressive enemy outside the city, and his heart felt heavy.

"Purple Heart, do you really have the courage to face the enemy in front of you with me? Even in it, there is your dustless brother. ”

Xue Lingjing brought Qin Zixin to the highest part of the city wall, and the army under the city was in full view.

"Xue Lingjing, I'm just guarding the place that my father is desperately guarding. As for Brother Wuchen, I can't tell you. ”

Qin Zixin looked at the military array in front of him, the neat and uniform team, with stones, bows, crossbows, and chariots all available, it seemed that he had been prepared for a long time.

"I'm glad you brought those people together, but in the end, they just died in vain."

Xue Lingjing sighed softly, but the serious ruthlessness was not reduced by half, if he wanted to level the land of Xue Guo, he had to step over his Xue Lingjing's body first.

"I don't think so, isn't there no news about the general Xue Lingqi yet? In my opinion, he must be trying to sneak up on the enemy's rear, and all we have to do is see the right time to flank him back and forth. ”

Qin Zixin walked in front of Xue Lingjing, she knew that Xue Lingjing knew this, and it was only by her that she could prepare for the next step.

"It's about how we can hold on until the time comes."

Xue Lingjing was really shocked by Qin Zixin's analytical ability when he heard this, but he thought of what the Taoist he met before the Royal Hunting Conference said: "This woman's life is Qingqi, if she comes back from the dead, she will give birth to Zi Weixing's life, the Lord King's Dao." And it calmed down.

"Under the palace of Xue Guo is an underground palace, and there are all the things in it, which is more than enough to supplement the recent war consumption. In addition, in order to persist in this battle, it is necessary to gather the craftsmen of the whole city, and send more than 1,000 people to the moat to fish out the fish inside and make fish oil. ”

As long as you let go and look for it, you will definitely find the entrance to the dungeon again, Qin Zixin said while looking at the map.

"The dungeon? Okay, I'll send someone to do it. Only, what do you want these things for? ”

Xue Lingjing looked at the person in front of him, smart mechanism, but his thoughts were very weird.

"You'll know that tomorrow. I also want 800 men to go with me to the Black Tiger Mountain in the Imperial City. I don't understand this transfer of troops, all I can do is try my best to help the soldiers who are fighting. ”

Qin Zixin put away her smiling face, and said with a serious face, from today onwards, I, Qin Zixin, may be a sinner.

Qin Zixin took the group to Black Tiger Mountain, remembering that Yue Wuchen had brought a piece of sulfur soil back to the Prime Minister's Mansion before, and he seemed to have said that it was from Black Tiger Mountain in the Imperial City. Qin Zixin rummaged and picked up halfway up the mountainside, digging different places.

"Found it!" Qin Zixin put the sulfur soil in the palm of his hand and looked at it carefully, it was the weapon of Zuihou who turned defeat into victory in Xue Guo.

"Ladies and gentlemen, I'll show you the clods in my hand, and then we're going to dig them up and transport them back to the city down the mountain, understand?"

Qin Zixin raised the sulfur soil high in his hand to signal. As a result, baskets of sulphur soil were excavated and sent to the imperial city.

With the help of Qingping, Qin Zixin collected basketball-sized earthen pots containing oil, salt, sauce and vinegar from people in the city, and even took out the wine jar ceramics of some rich and noble families.

Qin Zixin led everyone to put the refined fish oil on the bottom third of the jar, separated it with kraft paper in the middle, put one-third of the separated sulfur and charcoal mixture of the jar on the kraft paper, and then sealed it with a cloth, and coated a layer of fish oil on the cloth.

The confrontation outside was stalemate for three days and three nights, and Qin Zixin also accompanied the craftsmen to make fish oil bombs for three days and three nights.

"Purple Heart, are you sure these things are useful?"

Xue Lingjing looked at the various strangely shaped jars piled up on the side of the streets in the city with a crying and laughing eye, did he want to use these to confront the 700,000 enemy troops outside the city?

"Qingping."

Qin Zixin looked at Xue Lingjing's questioning expression, and called Qingping confidently. Qingping walked over to a small jar, lit the sealed altar coated with fish oil, and threw it at the distant city wall, and with a bang, a pit suddenly burst out of the city wall, and a large fire ignited around the pit.

"Good! Pass the order down, continue to produce, and don't slack off for a moment! Xue Lingjing held the hilt of the sword tightly, it seemed that it was the endless Xue Kingdom.

"As long as you combine this with a trebuchet, you can hold on for a while." Qin Zixin looked at Xue Lingjing.

"Purple Heart, how did you come up with this?"

Xue Lingjing's brows that had been entangled together for a long time also stretched, what made him care was this Qin Zixin, who was not amazing, how did she know this, such a weapon had never appeared so far, if there were these, it would not be impossible to unify the world.
