Shopkeeper Cao laughed, "These seven insects and seven flowers and plants, it's not a strange thing, the sea outside the city, if you are willing to dive into the deep sea area, you can find one or two with some effort, this thing is not expensive, one is worth a spirit stone, only some fishermen in the city are willing to work hard for it." Pen, fun, pavilion www. biquge。 info”

"The reason why this thing is called Seven Insects and Seven Flowers is because this grass has different forms, it turns into insects every winter, and the rest of the time is grass, and after seven years of reincarnation, it is a fixed comfrey, which is considered to be adult. This grass has a wide range of functions, can be used for dishes, the strength of food is greatly increased, and the children of rich families use this thing to replace the blood of fierce beasts, increase strength, and the effect is excellent. ”

"It can also be used as medicine, and occasionally into Dan, of course, some sea beasts are also very fond of this thing and feed on it. However, these functions can be replaced by herbs next to them, but I don't know why these seven insects and seven flowers are the only ones that are favored recently, and the stocks of the major shops in the city are almost sold out. ”

Xu Yi frowned slightly, "Thank you Shopkeeper Cao for seeing me." ”

So he went into the refining room.

Entering the refining room, Xu Yi checked the privacy according to the process, and after confirming the safety, he released the Divine Hidden Bead, completely blocking this space.

Immediately, he took out the fourth-order Bailing battle suit, but saw that the battle suit was covered with lines, dilapidated like a spider web, and was greatly damaged.

At that moment, Xu Yi hurriedly threw a medium-grade spirit stone into the groove on the chest of the battle suit, but when he saw a faint halo around the battle suit, it entered a state of self-repair.

However, with half a pillar of incense, the medium-grade spirit stone was consumed, and most of the cracks around the suit were eliminated.

Xu Yi once again invested in a medium-grade spirit stone......

If it was repeated, it took a full four medium-grade spirit stones to consume, and the entire Bailing suit finally returned to normal.

And there are only seven medium-grade spirit stones left in Xu Yi's bag.

If there is another terrifying battle with Yun San Gongzi, it is obvious that this little inventory is not enough to support it.

Putting away the Bailing suit, Xu Yi took out the newly purchased time hourglass, placed it aside, and began to replenish water and cook meat.

After everything was ready to stop, Xu Yi got up and walked towards the staircase that extended down in the right corner.

After crossing dozens of stairs and reaching the underground, it was a refining workshop.

In the middle is a tall bronze tripod, and under the bronze tripod, is a fire trough closed by a wide iron plate.

Far away, there was a compelling scorching heat.

This refining room was specially selected by Xu Yi, and the reason why he was chosen here was because he took a fancy to the pure leyline fire in this refining room.

His retreat this time was to impact the fire talisman.

The reason why he came to this pass to Chongcheng was because he knew that there would be a disaster, and he also ventured here to protect the safety of Lord Yinqiu.

For the lord of Yinqiu, he really felt guilty in his heart, and he only hoped that she could marry into Guide Road safely and not be in danger on the way.

Speaking of which, this kind of expectation is a bit bad, and he even knows that the prince of the Yun family does not take this Yinqiu County Lord seriously, and maybe he will suspect that he has a personal relationship with the Yinqiu County Lord.

Even so, what could he do?

He understood the painstaking intention of the Yinqiu County Lord to let him go, it was nothing more than that he didn't want him to get involved in the turmoil, but he couldn't do anything for the Yinqiu County Lord at all, because of the difference in strength, he was destined to do something wrong.

He came here only to escort him secretly, hoping that the Lord of Yinqiu would get out of this pass and Chongcheng safe and sound.

To escort, strength is naturally needed.

After a battle with Yun San Gongzi, he knew very well that with his current strength, in front of a real powerhouse, it was nothing at all.

The only ones that can quickly improve their strength are the Talisman Technique, the Wind Talisman and the Swift Body Talisman, which are obviously not in this category.

What he wants to impact is the fire talisman with the number one attack power, and he still has nearly a month to calculate the time to send the family team into the city.

A month is enough time for him to make an impact.

Xu Yi expanded according to the motive and put it into the ground fire, and a large area of dark blue flames rose to the ground.

Xu Yi took out a Sumeru ring, dripped blood, thoughts invaded, and several array flags were moved out.

This set of array flags was rented by him here, and the deposit alone cost 10,000 spirit stones, and the rent was as high as 100 a day.

This is exactly a set of Spirit Gathering Array Banners.

In terms of efficacy, it is obviously not as good as the Spirit Gathering Array in Leng Yang Peak, but it is better than being able to carry it with you.

Right now, if he wants to impact the fire talisman sacrifice and study the permutations and combinations of several sets of fire talismans, he will have to consume a huge amount of fire-based spirit stones.

With this Spirit Gathering Array, it can greatly reduce the ineffective waste of fire-based spirit stones.

According to the method of arranging the formation in the formation book, Xu Yi quickly arranged a suggested spirit gathering array.

Sitting cross-legged in the array, he took out a fire spirit stone and landed in the dry position, and a fire rune paper fell in front of him, urging the spirit to be introduced, and at that moment, a faint purple light came out of nowhere, and it spread towards the fire talisman, and soon on the fire talisman, it pulled out a rune that could only be perceived and could not be observed with the naked eye.

Xu Yi is now familiar with the runes needed for sacrifice.

The flame explosion talisman he wanted to refine required was no more than thirty runes in total.

And the thirty runes, which eventually formed more than a hundred structures, formed the Flame Explosion Talisman.

And these more than 100 structures, after careful calculation, are actually composed of 12 basic structures, arranged and combined.

And because of this flame burst talisman, there are defects, and according to his incomplete deeds, he has completed 28 of the more than 30 defects, and only three cannot be completed.

After his calculations, it only took more than ten times of trial and error to completely complete those three places.

The entire Flame Burst Talisman can be fully restored.

Xu Yi's current job is not to complete this flame explosion talisman, but to use runes to build twelve basic structures.

Once these twelve basic structures are successfully built, it is possible to complete the runes through trial and error.

In other words, as long as these twelve basic structures are successfully built, the entire Flame Burst Talisman will be more than half successful.

The rest is basically water grinding, constantly running-in, skillful, and naturally formed.

However, building a structure is a painstaking and complicated project, and Xu Yi has tried it before, which is extremely difficult.

Now, however, he is particularly confident in building it.

First, the fire spirit stones were well prepared, and thousands of fire spirit stones were enough to support the entire complex and huge experiment.

In addition, his current fire-based rune paper is also very well prepared, compared to the trial rune, the fire-based rune paper is more pure, and it can increase the success rate of fire-based rune construction.

The three are also the most crucial point.

Now that he has cultivated the True Spirit Circle, he has cultivated his Divine Thoughts, and the strength of the True Soul is by no means comparable to that of the Yin Soul.
