Chapter 340

Why did it fail on the first try?

This way he can only improve it normally, but it's meaningless for Zhao Chi.

Forget it, no point burning this improvement book — he can sell it later, it's worth about 2 gold coins.

Once more!

He took out a new improvement book.

After a series of operations.

〖Data Transfer Successful〗

Zhao Chi let out a breath of relief, putting all the improvement points into brightness.

【Your improvements are as follows】:

【1. Brightness 100%】×10

【Confirm?】

He clicked confirm.

A strange, indescribable something dispersed.

The system sent a prompt:

【Congratulations, your territory has already mastered the "Ultra-Bright" Fire Oil improved technology】

【Item】 Ultra-Bright Fire Oil

【Effect】 Flame Brightness +1000%

【Description】 Through extreme brightness improvement, the fire oil achieves an extremely bright effect, far brighter than Gao Liang fire oil.

Not bad.

A normal improvement only adds 100% brightness.

Zhao Chi's territory directly became 10 times that — 1000% brightness.

This way, the increased brightness outside can also bring extra light into the room.

Even without lighting an oil lamp inside, it won't be too dark.

Unless the doors and windows are shut.

The description says it can turn night into day — that's a bit exaggerated, but it gives a sense of how effective this Ultra-Bright Fire Oil is.

Once the oil refinery is built tomorrow, he can transfer some workers to start producing it.

Zhao Chi continued to take out the last "Fire Oil Improvement Book."

He still activated Borrow Flowers, Graft Jade.

And transferred the 2 improvement points from cleanliness to brightness. Then transferred the 1 improvement point from safety to cleanliness.

This became:

【1. Brightness 100%】 2 points

【4. Cleanliness 25%】 1 point

〖Current data compatibility — transfer success rate is 44%. Confirm? 〗

The probability is even lower.

Just now, transferring one item had a 66% success rate.

This time transferring two items, the lower probability was expected.

It's already like this anyway — confirm!

〖Data Transfer Successful〗

Hmph!

Zhao Chi immediately made his selection.

【Your improvements are as follows】:

【1. Brightness 100%】×2

【4. Cleanliness 25%】×6

【Confirm?】

Confirm.

Likewise, a strange, indescribable something evaporated.

This meant another new technology had been mastered.

The system sent a prompt:

【Congratulations, your territory has already mastered the "Clean" Fire Oil improved technology】

【Item】 Clean Fire Oil

【Effect】 Flame Brightness +200%, Cleanliness +150%

【Description】 By changing the ratio, the fire oil achieves cleanliness, and incidentally gains some brightness, making this fire oil very suitable for indoor use.

This fire oil's brightness increased by 200%, already quite bright — more than enough for indoor lighting.

But most importantly, cleanliness increased by 150% — very clean.

After all, according to the original improvement data, even putting all points into cleanliness would only add 125% cleanliness.

Now it's 150% cleanliness.

Once lit, there's almost no smell.

In this case, a few more oil lamps can be lit indoors.

But there's no real need — after all, this fire oil also adds 200% brightness, which is enough.

A perfectly flawless technology.
