"Alright then!" Nangong Zhao'an pursed his lips, once again took out the appearance of a little daughter-in-law, got up aggrievedly and walked out lightly.

After walking out of the door, a certain master burst into tears, infinitely sad......

Yun Bing looked at a certain master and couldn't help but shake his head, his expression changed too quickly, right?

After being helpless, Yun Bing once again mysteriously slipped into the medicine room of Xuanying Pavilion, and took out a full amount of cherished medicine, and the guards who were guarding it on the side did not dare to say a word, this is the master's mother, the princess, and the person on the tip of the master's heart, who dares to provoke?

That's absolute death.

Yun Bing picked up the medicine that came out of the medicine room, returned to Nangong Zhao'an's room by himself, lit a red candle, and took out an iron thing, there was also a film on top of the iron thing, and a black and purple powder was placed in it, and it was ground on the fire for a long time, and finally two black and purple solids were separated, and there was a gas that smelled very clearly.

Yun Bing used his holy power to collect almost pure oxygen, and these will definitely be useful!

Yun Bing looked at the manganese dioxide and potassium manganate separated from the iron lid, and smiled, with manganese dioxide, oxygen can be better produced, and then you can make bombs!

Yun Bing used manganese dioxide to isolate more oxygen again, and after collecting it, he went out to buy some gunpowder, Xiao bamboo, saltpeter, and then bought a few pill boxes for refining pills, with pill-shaped boxes on them, which could just be shaped!

Condense the holy power into a thin film and attach it to the box, and add about two-thirds of the saltpeter, four dollars, and gunpowder of six dollars, and then add about two-thirds of the oxygen to make a slight bomb.

Yun Bing then made a few more and put them in the storage ring, and then made almost five more, preparing them for Nangong Zhao'an.

Being in the royal family, you may have to suffer some persecution every day, so it's good to bring a few to defend yourself.

*************************

At night, when Nangong Zhaoan finished dealing with the affairs of Xuanying Pavilion, he found that Yun Bing, a naughty little girl, had already fallen asleep on the side, and there were a bunch of things on the table, what bowls, boxes, candles, iron spoon-like things, all over the table.

Nangong Zhaoan touched Yun Bing's hair helplessly, with a wave of his sleeves, all the things on the table disappeared, and he fell asleep with Yun Bing in his clothes.

The wind guarding the door outside is speechless, master, do you have to pack up your things and hit me on the head?

At this time, Feng Ling was covered in wax oil, and there were still two iron spoon-like things hanging in the bun on his head, and a few boxes were scattered on the ground, but the things in the boxes were obediently lying in Nangong Zhao'an's storage ring.
