The prince kissed her seven times in one night, and the abandoned woman was scared!

Just as he was distracted, a fawning and handsome face appeared in his sight. The Fifth Column assured Yun Suyue with a playful smile, "Thank you, Princess, for taking me in. I will definitely work hard and study hard. I am not afraid of hardship or death. You can let me go into the frying pan, but I will never go into the mountain of swords..."

He may be emotional and his speech may be a little slurred.

"Straighten your tongue before talking to me." Yun Suyue slapped his handsome face, signaling the other two to start work.

The fifth column: “······”

"Hahaha~" He was not angry and followed Yun Suyue happily.

Yun Suyue handed Diwu Xiao three small porcelain bottles filled with healing potions, pointed at the three people in the Fifth Column and said, "When you have a good shot, blow one up and save the other."

Diwu Xiao: “…”

He instantly felt the herbal water in his palm was very heavy. This was no longer just herbal water, it was the lives of three people, including his own brother. "Okay, leave it to me."

Diwu Xiao nodded heavily. He was a security guard and didn't know anything about gunpowder research. He jumped onto the towering tree and protected the four people below from above.

Half an hour later.

The first batch of new iron eggs were produced. The four of them were covered in dust and dirt, and one could only tell who was who by their figures. The clothes they wore were all the same black.

Yun Suyue and Diwu Zong each held an iron egg in their hands. The four of them stood side by side, looking at the pile of ruins in front of them. They smiled so hard that their facial features could not be seen, only their white teeth were exposed.

Suddenly: "Bang!"

Yun Suyue threw the iron egg in her hand onto the pile of rubble, and immediately there was a loud noise like a landslide. But, "Huh? How could the sound come from underground? The iron egg didn't explode?"

"I'll go take a look." Diwu Zong handed the iron egg in his hand to Yun Suyue and ran over.

As a result, before the Fifth Column reached the ruins, there was a loud "bang", the ground flew upside down, and the surrounding earth collapsed. The Fifth Column was blown away with screams, rolling in the air with the debris.

"A Zong?" Diwu Xiao swooped down, caught Diwu Zong, took him away from the area and quickly fed him medicine.

Yun Suyue shouted across the bamboo forest, "How's the Fifth Column?"

Diwu Xiao: "He's still alive and conscious, just superficial injuries."

Yun Suyue was relieved. Pointing at the ruins of the test field, she said to the two people beside her, "This is far from enough to kill. The red saltpeter needs to be doubled. Do you two still dare?"

The two looked at the horrible looking Fifth Column, who was being helped back and limping, and gritted their teeth: "Dare!"

"You're so brave. Let's get started." Yun Suyue put her hands on their shoulders, giving them brotherly encouragement, and the three of them started tinkering again.

Diwu Zong didn't dare to miss any details, so he was supported by his brother Diwu Xiao and sat on a big rock to watch carefully.

This time it took a shorter time. After an incense stick of time, the improved version of the iron egg was born. Amid the joy of the four people, Yun Suyue threw an iron egg: "Bang!"

Ten meters away, the bamboo forest was not blown down, but a big hole was blown out in the ground, and it seemed that something else was blown out.

Yun Suyue frowned, "The killing power is still not enough, add more red saltpeter."

The two men happily picked up the explosives and said, "Princess, look what this is?"

"Hmm?" Yun Suyue took a look at what the two of them were holding. "Oh my god, beads? These are of quite good quality. Hurry up, go find them. There must be more. We're going to make a fortune!

Although Teng Yan is not a good person, he has a lot of good things. I said that when I searched his room before, I didn’t find anything valuable. It turns out that they were all buried underground, hahaha~"

Yun Suyue was laughing so hard that she completely forgot what she was doing there. The four of them covered their faces and could only help her pick up the things.

After a quick search, Yun Suyue picked up a lot of good things, all of which were wrapped in a cloth bag.

But the only thing missing is the mother corpse worm. It doesn’t matter. All the corpse worms of the Holy Emperor have been forced out. If I can’t find it, I won’t study it anymore.

After that, it failed again and again, and the lethality did not meet Yun Suyue's requirements. He tried again and again, and finally, after failing dozens of times, even Yun Suyue himself was injured by the explosion.

If she didn't have the space in her hands, where she could hide in time and drink the spiritual spring water to repair her injuries at any time, she would probably be disabled if not dead.

Not to mention the three people. Even though they had potions to repair themselves, they were still badly injured by the frequent explosions.

In this way, two satisfactory iron eggs were finally made. One has just been tested and destroyed a large bamboo forest. The other one was taken back to report.

It just so happens that all the red saltpeter has been used up, and we are just waiting for the five pounds from Tai Youqian. Once it arrives, we can produce it in batches and send it to the border urgently.

Yun Suyue did not rush back immediately, but asked each of the three of them to record all the steps clearly, not with notes, but with their brains.

Then he repeated it to her again and again, making sure that everyone had understood it without any mistakes, and then let them go back to recuperate.

Diwu Xiao saw that Yun Suyue had no intention of leaving, so he asked her, "Does the princess have anything else to say?"

Yun Suyue looked at the collapsed bamboo house and said, "I feel like there might be treasures under the foundation."

Diwu Xiao: “…”

The princess was really crazy about the treasure and would not let go of even a single valuable hair. He had no choice but to blow up the collapsed bamboo house with a palm, letting Yun Suyue search for the treasure herself.

But this time, there was nothing inside except a heavyweight dark purple wooden box. "What is this?"

She circled the purple wooden box twice, it was closed, unlocked, and when she shook it, she knew there was something inside.

Diwu Xiao drew his sword, "I'll try to chop it from the side."

"Okay, try using one level of your skill." Yun Suyue stepped back.

Diwu Xiao controlled his strength and slashed down with his sword. "Snap!" Not only did the wooden box not break, but his sword and the box rubbed against each other, sparks flew and were blocked back. Even though he had seen such a big scene, he was shocked.

"What kind of wood is this? It can actually block my sword and even discharge electricity. Let me try it with 30% of my strength."

"no need."

Yun Suyue waved her hand. She was now more interested in the box. "I think I know what kind of wood this is. It must be the Ten Thousand Years Purple Thunderwood. It grows in the shade deep in the mountains. It never sees sunlight all year round, but it can absorb lightning. It takes hundreds of years for its annual rings to grow one circle. The wood is extremely fine and dense, making it a very rare treasure tree.

It is not afraid of water, fire, thunder or lightning and is extremely precious. It is the main wood used by emperors of all dynasties to build purple gold coffins. It seems that the emperor is lying in the purple gold coffin made of this wood.

Looking at the wood grain, it's not the core of the tree, just scraps. It's already extremely valuable and can't be split."

Yun Suyue quickly picked up the box and examined it. She realized that it had no lock, but was equipped with a mechanism. "I don't know how to unlock it either. Let's take it back first."

She dared to guarantee that anything that could be put in such a box must be a rare treasure. Teng Yan, a man who was driven out of Baiyao Valley, definitely did not have such a good thing. This thing must have been stolen from Baiyao Valley and buried underground by him.

She just didn't know what was inside, she hoped it was a female corpse worm.

After returning to the palace, Yun Suyue asked the Holy Emperor to call a master of mechanisms, who took a long time to open the box.
