As he returned to the Cai Family mansion, Jia Hao spent his days in leisure. Old Yang brought him some of the sample weapons used by the soldiers.

'' These are simply made from pig iron. So hard and brittle. The grains inside are also very uneven.'' Jia Hao inspected the items.

However, as these weapons were mass produced for the war, quantity is more appreciated than quality.

Besides, the quality of the iron was poor. Because, most of the time, the scrapped weapons and armor collected from the battlefield and melted directly.

After separating the impurities, the remaining material is used to make more weapons.

However, after such tempering in flame, the recycled sword becomes more brittle, impacting its performance.

But when he checked the sword, Old Yang was surprised.

" Old Yang, Why your sword is almost three times better than these ordinary swords?"

" Because it''s made by a renowned blacksmith with Millenium Yin Iron. Meanwhile, these swords are made of simple cold iron." Old Yang explained.

'' Ah, How could I forget? Yunlan continent is filled with magical herbs and treasure ores. I can''t use my modern world logic here."

" Then how does this Millenium Yin Iron is made?"

" It''s condensed from the Cold Iron and can naturally extracted in the deepest parts of old mines. It can be created with ordinary cold iron too, but the process is too lengthy and takes a month to build weapons with it."

" There are various sects and families who build special weapons. However, those weapons range from few tens of thousand taels of gold to a million taels of gold."

" Meanwhile, the ordinary sword can be bought with a hundred taels of gold or less."

" Cai Family forges mostly smaller things, like knives and farming tools. We also produce weapons, but they were sent to the Imperial Army."

" Wait a minute." Jia Hao''s eyes sparkled. " You mean, If the Cold Iron ore refined quickly, we can use its essence to make Millenium Yin Iron?"

" Uhh, Technically, Yes?" Old Yang nodded.

" However, that''s pretty difficult to do. Besides, smelting and tempering the billet also requires a lot of skilled people. A single weapon might take an entire day to be built."

" You don''t need to worry about that, Old Yang." Jia Hao grinned as he thought of an interesting method.

'' If this succeeds, I would be able to manufacture enough weapons for the Cai Family.''

In the evening, good news came from the Fragrant Medicine Pavilion.

Since Jia Hao asked Pharmacist Mo to prepare the antidote days ago, the treatment was very efficient. In the evening, Sang Qian''s body completely expelled all the poison.

He could feel the strength returning to his body as he could now move his internal qi without any pain.

As Jia Hao was enjoying Minmin''s massage while sitting on the chair, Sang Qiuliu arrived before Jia Hao.

" Greeting, Young Lord Jia. I hope I am not disturbing you?"

" Not at all." Jia Hao chuckled. " For beauties, my door is always open. Ouch!"

Minmin glared at Jia Hao when she heard Jia Hao''s cheeky statement. '' How dare he compliment another woman in this household?''

Sang Qiuliu giggled lightly as she looked at Jia Hao. " I never expected Fragrant Medicine Pavilion would be efficient. As part of my deal, I have brought a comprehensive map of Wolves Fountain."

" This map is different from the ones out in public. I have also marked various monster territories and locations of various herbs and natural treasures."

" Thank you for your effort, Miss Sang. I shall be grateful to you." Jia Hao smiled politely.

*PAA! PAA!*

" Ahn!~"

Minmin''s face turned red as she hopped back like a rabbit. Rubbing her aching buttcheeks, she couldn''t help but glare at Jia Hao with a teary gaze.

" Yo-You! Shameless! Pervert!"

Jia Hao laughed loudly, but his slaughter froze as he saw Cai Yixue standing in the distance, looking at everything unfolding before her eyes.

" Uhm, Wife...I can explain..." Jia Hao tried to say something, but Cai Yixue just gave a disappointed shake of the head and walked away.

" Hmph! You deserved it!" Minmin couldn''t help but gloat at Jia Hao''s plight. However, when Jia Hao looked at her again, she walked back several steps.

" It looks like I need to teach the maid some lessons."

" Wahhh! Son in Law is bullying me!"

Later that night, Old Yang appeared before Jia Hao and cupped his fist.

" Young Lord, As you asked, Ten crates full of iron ingots are prepared."

" But, Young Lord, May I know what are you going to do with all this iron?"

Jia Hao laughed when he heard that. " Well, I also wonder. I have a plan my mind. But I need to see if it''s working or not."

" Since you have delivered the items, you can go now."

" But Patriarch wishes to meet you..."

" Nope, Tell him I am tired to today and wish to rest. Besides, I need to go out tomorrow. " Jia Hao made an excuse. He doesn''t want more work dumped on him.

As Old Yang left, Jia Hao stored all the crates in his Pot of Miracle and went to sleep.

'' Let''s see if it''s working or not.''

Jia Hao put various herbs along with the crates, hoping to see the result of the deconstruction.

He stayed here for over three days in Yunlan Continent. So more than half a day passed in Azure Sea World.

Opening his eyes, he realized 300 Chaos Points were completely spent.

The original pile of ten crates worth of iron ingots were reduced by sixty percent, leaving a lustrous pile of dark iron.
