"It's alright, Uncle. Don't be afraid. We'll deal with whatever comes our way!"

Hearing Shen Chuan's father's worries, Lin Feng smiled calmly and said without any fear.

He believed that the floating island would definitely not send a high-level grandmaster to seek revenge.

As long as the other side doesn't send out high-level grandmasters, he has nothing to fear.

After all, with his current cultivation level of Grandmaster Level 6, coupled with his extremely terrifying domain power, dealing with people below Grandmaster Level 7 is still not a problem.

He could even fight against a seventh-level grandmaster.

If the people on the floating island really want to continue sending people to retaliate against him, they will most likely become experience points for him to continue leveling up!

Therefore, he was not worried about the floating island's retaliation at all; in fact, he was even looking forward to them sending people to their deaths!

Seeing Lin Feng's confidence, Shen Chuan and his son exchanged a glance and breathed a sigh of relief.

Although they didn't know why Lin Feng had such inexplicable confidence.

But Lin Feng's previous performance filled them with confidence in him!

Since this guy isn't afraid of retaliation from the floating islands, he must have some kind of confidence.

"Uncle, Brother Shen, I'll leave the aftermath here to you. I'll go back and make some preparations in case the people from the floating island attack again!"

Lin Feng said with a smile.

"Alright, young friend, you can go ahead and get busy. We'll take care of cleaning up this battlefield!"

Shen Chuan's father immediately nodded.

Afterwards, Lin Feng returned to the Lin residence.

After returning, he carefully examined the storage rings of Jin Ao and the others.

Besides the spirit stones and cultivation techniques, he also found many good things in these people's storage rings.

Among them are precious materials for alchemy and weapon crafting, as well as some mid-level Earth-grade martial arts techniques and mid-grade Earth-grade artifacts!

"A mid-level, Earth-grade, Metal-attribute sword technique?"

As Lin Feng flipped through the mid-level Earth-rank martial arts manual, a look of anticipation appeared in his eyes.

It should be noted that his current martial arts skills are all at the initial stage of the Earth level.

After learning this mid-level Earth-rank martial art, his martial arts skills will be upgraded to the mid-level Earth-rank.

Moreover, based on previous experience, he only needs to learn one mid-level Earth-grade martial skill to simultaneously raise the level of all other martial skills to mid-level Earth-grade!

Once he upgrades his martial arts to the middle level of Earth rank, the level of his mastered domain will also be upgraded from the initial level of Earth rank to the middle level of Earth rank!

In this way, his strength will increase dramatically once again!

At that time, it might not be impossible for them to kill someone at the seventh level of the Grandmaster realm.

"bite!"

"Congratulations, host, for acquiring a mid-level Earth-grade martial skill. Would you like to spend 500,000 gold stones to learn it?"

As soon as Lin Feng opened the manual on sword techniques, a system notification sounded in his mind.

"Five hundred thousand? Not bad! Let's learn it right away!"

Lin Feng frowned slightly, hesitated for a moment, and then spent 500,000 yuan stones to learn this mid-level Earth-grade martial skill.

Five hundred thousand shi was nothing to Lin Feng before.

But after the upgrade, he only had a little over one million gold coins left.

Five hundred thousand shi (a unit of dry measure) is almost half of his current wealth, which is why he hesitated for a moment.

As soon as he learned this martial art, his understanding of the metal attribute domain was directly upgraded from the initial stage to the intermediate stage!

Moreover, because he was upgraded through the system, the power of his intermediate-level domain is comparable to that of others' advanced-level domains!

After his domain level was upgraded, Lin Feng's strength also increased dramatically.

"The intermediate level is indeed different!"

With a thought, Lin Feng released a mid-level metal attribute domain. A golden sphere of light immediately appeared around him, radiating a terrifying metal attribute power. Its power far exceeded that of the metal attribute domain that Ba Jin Ao had released before, and was even much stronger than the lightning attribute domain that he had used before.

If Lin Feng were to face Jin Ao now, with just this mid-level metal attribute domain, he could directly imprison Jin Ao in the air, unable to move an inch. Or even, he could directly use the powerful force of this mid-level metal attribute domain to crush Jin Ao's body!

"To upgrade other attribute martial arts techniques to the mid-Earth rank, each technique requires 500,000 Yuan Stones? Besides the Gold attribute martial arts techniques, I have eight other martial arts techniques. To upgrade them all to the mid-Earth rank would require a full 4 million Yuan Stones? That's damn expensive..."

Looking at the cost of upgrading martial arts skills on the system panel, Lin Feng couldn't help but frown. "What's worse is that as the martial arts skills are upgraded and the domain level is raised to the middle level of the Earth rank, the fusion level is still the same as the initial level domain. And if I want to fuse these nine middle level Earth rank domains together, I will have to pay Xu Village a full four million yuan stones!"

"These two expenses combined amount to another eight million shi (a unit of dry measure), this is truly spending money like water!"

Lin Feng originally thought that he was already rolling in money compared to his peers, but now he felt like he didn't have enough money at all.

After thinking for a moment, Lin Feng spent another 500,000 yuan stones to upgrade the level of his lightning-attribute sword technique to the mid-level Earth rank!

At the same time, his understanding of the lightning attribute domain also improved from the initial stage to the intermediate stage!

As a result, his strength increased dramatically once again!

After that, he only had two or three hundred thousand spirit stones left, which was not enough to make any upgrades.

"Spirit stones really don't last long. It seems I need to hurry up and find new customers for spending money and getting rebates. Also, I need to keep selling pills, weapons, and equipment!"

Lin Feng pondered, "Furthermore, to continue upgrading, money alone is not enough; we also need to find more advanced cultivation techniques and martial arts skills!"

"We can't count on Flying Dragon City anymore; our greatest hope lies on that floating island!"

"Hopefully they'll send someone to retaliate soon..."

"But if they don't come... then I'll have to go to bigger places to look for opportunities!"

"The capital of the Great Jin Kingdom would be a good choice..."

After making his plans, Lin Feng immediately began using the materials he obtained from Jin Ao and the others to refine pills and weapons, which he then sold.

Thanks to the reputation he had built up from selling pills and equipment, Lin Feng's business was even more booming this time.

Almost as soon as he refined a pill or a piece of equipment, it was immediately bought by someone at a high price!

Later, in order to compete for the pills and equipment he refined, buyers in the city even took the initiative to start a high-price pre-order mode, which caused the price of Lin Feng's items to soar several times!

...

While Lin Feng was busy with his business, on a floating island thousands of miles away...

The withered old man who sent Jin Ao and the others to seek revenge also learned of their demise through the life-bound soul tablets left by Jin Ao and the others in the sect.
