"It's actually..."

Li Lanzhen opened the bundle and saw six round, dark lumps the size of apples. "These are the latest hand grenades you've developed. Good! Very good!"

Xuan Shen raised her eyebrows triumphantly.

Li Lanzhen taught Xuan Shen the material ratio formula for making hand grenades and explosives. In recent years, they have been continuously researching and developing the size of hand grenades.

The first few batches of hand grenades were too large and inconvenient to carry. Later developments either resulted in grenades that were too small but lacked power, or too powerful but were too small…

I've finally finished making one that I'm quite satisfied with.

Seeing that Li Lanzhen's mood had improved considerably while holding the hand grenade, Xuan Shen quickly said, "These should all be given to Han Yisong's Shenji Battalion for use. We only need to focus on developing firearms."

"Are Song'er and the others going on a special mission? Like an assassination? Infiltrating an enemy country to carry out an assassination?"

Xuan Shen did not answer, but lowered her head and pursed her lips.

Li Lanzhen understood his expression immediately, and she was also conflicted. Her children and grandchildren lived and were educated in this dynasty, receiving the emperor's salary and sharing his burdens, which they considered to be their due.

For Li Lanzhen, who is a mother and grandmother, she only cares about their own safety.

"Auntie, keep this. It can protect you if you encounter danger." Seeing that Li Lanzhen's mind was wandering again, Xuan Shen quickly said.

Li Lanzhen put the bundle into her spatial storage. "Thank you for your thoughtfulness." Although she had her own means and abilities to protect herself in case of danger, Li Lanzhen was still happy that Xuan Shen cared about her bodyguard.

Looking at Xuan Shen, who usually appears as a handsome and gentle young master, yet turns ruthless and fierce when facing danger and enemies, his swords sweeping away fallen leaves like autumn wind, Li Lanzhen watched this child grow up before her eyes, her eyes filled with loving affection as if she were looking at her own grandchildren.

“Xuan Shen, it’s time for you to find a good girl and settle down.”

Xuan Shen lowered her head and smiled bitterly. He was urging her to get married again. Why couldn't he say something else? "No rush. We'll settle down when we meet the right person."

Li Lanzhen knew how bitter this child was. After his parents passed away, his older sister took on the responsibility of caring for him and raising him. Before he could grow up and protect his sister, he watched as his sister perished in a fire.

This kind of pain is hard to understand without experiencing it yourself!

Li Lanzhen stopped trying to persuade her, saying, "Let's go take a look at your medicinal herb field."

The two stood in the space. Li Lanzhen walked straight to the storeroom in the courtyard, and even turned back to call Xuan Shen to follow, "Follow me."

Upon arriving at the warehouse, Xuan Shen saw many supplies, some familiar and some unfamiliar.

In fact, by this time, the warehouse's inventory had already reached one-fifth of its original size, as it had been gradually used up over the past few years.

All that remained were books, some jade jewelry, and other items unsuitable for use, as well as mostly grains, fruits, and vegetables.

This caused Xuan Shen's pupils to shrink slightly, and his heart was filled with shock. This was too arrogant! He hadn't expected it, and of course, he couldn't have imagined it.

Aunt Lanzhen's secret place is so big! So... big!

Forgive me, I'm at a loss for words!

Li Lanzhen appeared calm and collected on the surface, but she knew the young man was terrified.

Hehehe, let me show you something.

"Take the Scrophularia ningpoensis yourself, turn it around and see what you want. Just take it out and keep it safe."

Li Lanzhen also checked what else was in her space, while glancing out of the corner of her eye to see what Xuan Shen was interested in.

Unexpectedly, yet also as expected, Xuan Shen headed straight for the Tang sword that was suspended two meters in the air.

Li Lanzhen and Ji Anxuan were curious about the Tang sword, which was not surprising, so they stopped and looked at him.

Xuan Shen reached out and covered the Tang sword. The sword remained still in his hand. Li Lanzhen was puzzled. She wondered which shop had given her the Tang sword in exchange for grain.

Li Lanzhen knew that the Tang sword had its own will, even though it could be used whenever she wanted.

Therefore, in critical moments, Li Lanzhen dared not use the Tang sword at any time, fearing that not being able to get the sword in a life-or-death situation would endanger her own life.

Xuan Shen looked at the Tang sword in his hand with great joy, gripped the hilt, and slowly drew the blade, with a hissing sound.

A flash of white light, and Xuan Shen and the Tang sword in his hand vanished from the spot...
