After Chu Han left the City Lord's Mansion, he went to the streets to find the materials needed for the Pearl Pill, most of these pills were produced on some nearby islands, if it was in the Middle Earth, it would naturally be hard to find, but here, the value was relatively half.

Of course, this is generally only relative to the alchemists of the Yuan Dan Realm, and for ordinary martial artists, each material is also a lot of money, but it is more common than other more precious things.

Soon, he had gathered most of the materials needed for the elixir, and only two materials remained.

One is called turquoise coral, which is a rarer material than blood coral, blood coral is blood-red all over, and it is relatively easy to find in the sea, while turquoise coral is in the sea, the same color as the seawater, plus it has the ability to isolate the divine sense, so it is extremely difficult to find.

In addition to the fact that it is difficult to find, it is often guarded by extremely powerful deep-sea spirit beasts around it, which makes many warriors with slightly lower strength shy away.

It is extremely difficult to find, plus there are few in itself, and there are spirit beasts to protect it, which leads to the fact that the blue coral is extremely difficult to see on the market, and it is priceless and marketable, and it is often monopolized in the hands of big forces such as the city lord's mansion, but the blue coral is not very useful, and refining pearl pills is one of the applications.

In addition to the lack of blue coral in Chu Han's hands, there is also a main material, which is deep-sea pearls.

There are a lot of this kind of material in Pearl City, but Chu Han can think with his toes that the higher the quality of the pearls, the better the effect of the refined Pearl Dan, so these pearls on the market can't enter his magic eyes at all, and even some pearls still have more or less defects in his eyes.

Chu Han originally relied on pills to improve his cultivation, so it was naturally better to maximize the use of pills, and if he could use the best pearls because of the resistance of each pill, he would definitely want to use the best pearls.

In addition to buying this pearl, you can also collect it yourself, and the stronger the warrior, the stronger the mussel sea beast that can be killed, so the higher the quality of the pearl you can get.

Since Chu Han didn't get the blue coral now, he wasn't in a hurry about the pearl, he wondered if he could find an extremely high-quality pearl by himself, which might be much more effective than using a low-grade pearl.

When he returned to the inn, he had a look of surprise on his face.

Because, he felt that the box in the bracelet space was responding again.

After he ascended to the Yuan Dan realm, the box slowly turned purple, and he set the box to produce auxiliary cards, and then after more than a month, the box produced the first card, that is, the purple auxiliary card.

The image on this card is of two souls, which are extremely distorted, as if they are about to be fused together.

"Fusion!"

Chu Han got the information of this card.

"Fusion, you can fuse any two cards of the same level except for the auxiliary card, and the cards that have been fused can not be fused again, and each time you use it according to the level of the fused card, you need to consume different yuan power. ”

After reading this information, Chu Han became excited, with this card, then the power of those cards in his hand will increase by another level.

Before, because his own combat power far exceeded his own cultivation, and those cards were only equivalent to his cultivation's combat power, so for a long time, winning the cards has become a bit chicken for him, but now that there are fusion cards, then after those cards are fused, the combat effectiveness will definitely be greatly improved.

And then he started trying.

If you experiment, then using a white card is obviously more economical.

After several trials, he came to a few conclusions:

The battle card is fused with the battle card, or the battle card, but the strength will be increased to more than the previous two cards combined, and the monster on the card is also a new fusion monster, combining the advantages of the previous two cards, such as a powerful battle card and a fast battle card fusion, then the newly formed card, the power is large and fast.

The battle card is fused with the magic card, and the formation is still a combat card, but the combat card will release this spell, and the restriction on the number of times the green ** magic card can be stored and used is broken, when this kind of combat card is in the bracelet space, it will spontaneously store the number of magic uses, and when the time comes, its own spells and the spells of the magic card can be released together, and the explosive power is extremely high.

The battle card and the equipment card are fused, this Chu Han has already done experiments before, but at that time he only installed the equipment card on the battle card, but now the two are completely fused, becoming a very unified and harmonious card, and the power is similar to the fusion of two battle cards.

The fusion of the magic card and the magic card is similar to Chu Han's own fusion spell, both of which combine the characteristics of the two spells, and the power of the fusion increases exponentially, but correspondingly, the yuan power consumed has also increased, and the time to store the number of uses has also increased, of course, this is nothing to Chu Han at all.

The fusion of magic cards and equipment cards will form a kind of equipment similar to enchantment, such as a knife fused with fire spells, then even if this knife is used by ordinary people, it can use the fire element power stored in it to release and kill, and this knife will also have an amplification effect on the release of spells by martial artists who use fire attribute element power.

The fusion of the equipment card and the equipment card will form an effect similar to a suit, such as a knife fused with a fist glove, then the activation card will get both a fist glove and a knife at the same time, and because the two pieces of equipment have been fused, the fit is very high, so that the warrior is more flexible and comfortable when using it.

Chu Han summed it up, the most useful thing for him here is the fusion of magic cards and magic cards, because this fusion is the most powerful and helps him the most, and the fusion of equipment cards and equipment cards is a bit chicken, but for martial artists who are generally in the same realm as him, it is quite good, and the others are just equivalent to increasing his power, not much to his own strength.

After summing up, he hesitated for a while, chose a blue ice-type magic card and a blue water-based magic card, and fused them to form a fusion magic card.

He then synthesized a few more pieces of blue equipment, but all of them were ice-based.

He was going to break some formation with the city lord this time, so he must not be able to bring Ouyang Mingyue over, and her safety needed to be guaranteed. At present, he doesn't have a purple card on his body, so he can only use the blue card first, these should be enough for Ouyang Mingyue, plus the Azure Jade Toad.

After doing this, he exited the bracelet space.
