Wei Feng was a little flattered and took the talisman handed over by Shi Yi.

For the people, the method of capturing the fire spirit is really not a secret.

On the contrary, the casual cultivators who have been mixed in the Fan country have been more or less exposed to this kind of work.

Even if Wei Feng doesn't teach them this skill, he can always try some ways if he tries a few more times.

His people are nothing more than helping Shi Yi and Lin Ao, saving the process of trying.

In this way, while the three of them were flying, Wei Feng told Shi Yi and Lin Ao.

How to preliminarily judge where there will be fire spirits.

After all, there are so many lava pools here.

It is impossible for every pool to have fire spirits.

Picking a location where prey exists is one of the most important skills to master.

Otherwise, even if you learn the ability to capture the fire spirit, if you can't find it, it will only be in vain.

"Actually, it's not that difficult to find the fire spirit.

This kind of Five Elements spirit is born with the power of the Five Elements, and where the power of the Five Elements is strong, there is a place where they like to stay.

Reflecting on the body of fire spirits like fire spirits, where the temperature is high, they like to stay there.

And if I want to judge the temperature of these magma pools, I usually judge by the color of the magma in the magma pools.

The darker the color of the magma, the lower the temperature of the magma pool, and the less likely it is to have fire spirits in it. Wei Feng explained for Shi Yi and Lin Ao.

With that, Wei Feng scanned the surrounding magma pools in mid-air, and immediately locked on to a target.

"Hehe, this time the luck is really good.

Look, if there is a bright white color in the magma like this, it is almost certain that there must be a fire spirit in it.

Because of this bright white magma, its temperature can almost be said to be the highest.

Again, the first-class golden yellow, although there is no guarantee of the absolute existence of fire spirits, but there is a relatively high chance of existence.

At the next temperature, the magma will appear orange.

The possibility of fire spirits in this magma pool is much smaller.

As for the dark red magma with the lowest temperature, that kind of magma pool can basically be skipped directly, and the fire spirits usually don't stay there.

Of course, if it is chased by monks.

Thus escaping into this magma pool is a different matter. Wei Feng pointed to a magma pool not far away, and introduced Shi Yi and Lin Ao.

Then, Shi Yi and Lin Ao came to the magma pool that they were referring to, together with Wei Feng.

I saw that the magma in this magma pool was the lightest in color, and in some places it was almost bright white.

However, Shi Yi knew very well in his heart that what Wei Feng said was right.

The temperature in this magma pool is indeed much higher than that of the surrounding lava pools, which are slightly darker in color.

After all, Shi Yi is an Ice Dao monk.

In addition to the fire tunnel, the ice tunnel is the most sensitive to temperature.

After determining the magma pool to attack, Wei Feng began to prepare to capture the fire spirit.

I saw that he casually took out two things from the storage pocket, which were a fishing rod and a fiery red stone.

"The next step is to lure the fire spirit out of the magma pool.

And these two things in my hand are prepared for this step.

The main body of this rod is made of adamum, which is extremely tough.

The silk part of the fishing rod is made up of filaments spit out by a strange beast called a fire spider.

In addition to the unusual toughness, this kind of silk thread is also characterized by not being afraid of high temperatures.

A fishing rod made of these two materials is ideal for fishing for fire spirits.

And since it is to lure the fire spirit to take the bait, it naturally needs bait.

And this fire core in my hand is the best bait. Wei Feng pointed to the tools in his hand and introduced.

Hearing this, Shi Yi couldn't help but nodded.

As Wei Feng said, this fire core is indeed the most suitable thing to use as bait.

Just like when Shi Yi was looking for a thunderbolt monk everywhere in order to make a lightning rod, he wanted to get the thunder core made by the thunderbolt monk.

This fire core was also made by a fire monk.

The principle of production is somewhat similar to the formation of metacrystals, which are the result of energy compression to the limit.

It's just that the Yuan Crystals can't be artificially made, they are the condensation formed by the Heaven and Earth Yuan Qi after thousands of years of squeezing in the depths of the stratum.

It is also the reason for the specific formation of the Yuanjing vein.

Because this formation process is often done at the very deep underground.

Coupled with the monk's detection magic weapon, it could not penetrate too deep into the stratum to discover this phenomenon of gathering the vitality of heaven and earth.

Therefore, the initial discovery process of the Yuanjing vein is often very difficult.

If you want to discover the metacrystalline veins, in addition to passively waiting for the stratigraphic changes, these metacrystalline veins are turned over the shallow soil.

All that remains is for the schools that have the relevant detection capabilities in the Way of the Spleen and Earth to carry out deep exploration.

However, this also requires a huge amount of manpower and material resources.

When Shi Yi was in Liuguo, there was a rumor in Liuguo.

It is said that the Yuanjing vein in Maruyama back then.

The reason why it can be discovered is that the Liutu land attribute monk occupies a lot of credit.

After the exploration was completed, the Yan Kingdom was only willing to pay a little compensation, and wanted to send away the monks of the Liu Kingdom who had discovered the ore veins at the beginning.

Maruyama is in the territory of the wild goose country, and people have to bow their heads under the eaves.

Monk Liu Guo was sent away, and he could only be helpless.

However, after returning to Yanagi.

The more these monks thought about it, the more angry they became, and they began to spread the word about how the forces of the Yan Kingdom did not speak of faith.

This matter soon reached the ears of the Guangling faction, and those who had a heart summoned those monks who had entered Marushan to explore the Yuanjing vein to inquire a little.

Through these people, after knowing that the Yuanjing vein has an amazing reserve.

As a result, the Guangling faction used this as an excuse to launch a scramble for the Maruyama vein.

The war between the Yan Kingdom and the Liu Kingdom also came from this.

For the resource-poor Liuguo, foreign expansion and plunder are the only ways to alleviate the shortage of resources.

In particular, Yuan Jing is widely used, it is not only the universal currency of the cultivation realm, but also the most widely used consumable.

Internal use can replenish the heaven and earth vitality in the monk's body, and external use can be used as energy for puppets, magic circles, and other devices.

Yuan Jing can be said to be a completely indispensable part of the cultivation realm.

If there is no existence of Yuan Jing in the cultivation realm, it will be no different from the human beings in the mortal world, returning to a primitive society that does not know how to use fire.

The reason why Yuan Jing is so widely used is because the nature of Heaven and Earth Yuan Qi is very stable and mild.

And the artificially created thunder core and fire core, although their means are similar to Yuan Jing.

And the energies of fire and thunder are essentially the changes of the Heaven and Earth Yuan Qi.

However, once the nature of the Heaven and Earth Yuan Qi has changed.

Then, the stable and gentle nature that it had in the beginning will be lost.

Artificial crystal nuclei such as fire cores and lightning cores are extremely energetic and abnormal.

Even if this kind of crystal nucleus is a monk of the corresponding school, he does not dare to pick it up directly as if absorbing the Yuan Crystal, absorbing the violent energy stored in it.

In addition, it is very rare to find a device that uses such an artificial crystal nucleus as an energy source.

I want to use the power of fire and lightning as an energy source.

That needs to be prepared for serious wear and tear of the device.

A golem or magic circle that supplies energy through the fire core or lightning core may be on the verge of damage if it is used slightly.

This level of attrition is unacceptable to most monks.

At the beginning, Shi Yi used the lightning core to make the lightning rod, and it was not for the purpose of using the lightning core as the energy source for the lightning rod.

It is simply to use the violent energy in the thunder core to attract and divert the attack target of the thunder tribulation, so as to share the pressure of the tribulation.

Aside from the fact that the energy in the artificial crystal nucleus is manic, they cannot replace the metacrystal.

There is also one of the most important reasons, that is, artificial crystal nuclei such as lightning cores and fire cores.

The price of one of them is much higher than the price of one yuan crystal.

After all, there was only a Fetal Breath Realm cultivator with a void fetal framework.

Only when you have the realm of the means of large-scale storage of heaven and earth vitality can you have the means to use compression.

The ability to create artificial crystal nuclei is a big manufacturing threshold in itself.

In this compression process, a huge amount of energy needs to be output to solidify the energy to form crystal nuclei.

Counting the energy that escaped in the process, it was far from enough to use the reserves of the Heaven and Earth Yuan Qi of the Fetal Breath Realm cultivator himself.

And this process of compression must not be stopped until the crystal nuclei are completely condensed and formed.

Once stopped, the energy will completely dissipate, which means that all previous efforts are lost.

And the only way to quickly replenish the Heaven and Earth Yuan Qi is to absorb the Yuan Crystal.

And the fetal breath realm level, because it is the initial stage of the intermediate level.

Whether it is the characteristics of the genre or the understanding of the vitality of heaven and earth, it is relatively superficial.

This makes waste inevitable in the process of condensing crystal nuclei.

Fetal Breath Realm cultivators often consume three to five Yuan Crystals to obtain an artificial crystal nucleus.

Because the versatility of artificial crystal nuclei is narrow, it can be said that it is a completely loss-making transaction in the early stage.

Therefore, under normal circumstances, there are few monks who will make artificial crystal nuclei by themselves.

It is precisely because of the small number that it was originally in the land of the soul of the talented country.

The vendor sold the thunder core and asked for three broken mirrors, and Shi Yi bought them almost without a counteroffer.

Considering the special environment at that time, the value of a broken mirror was more than half of a yuan crystal.

Converted, isn't that thunder core equal to about five yuan crystals?

Taking Shi Yi himself as an example, as an ice path monk, Shi Yi naturally also has the ability to condense the ice core.

As a Fetal Light Realm monk, his perception of the genre is much higher than that of the Fetal Breath Realm monk.

However, even if Shi Yi condensed the ice core, it would require at least one Yuan Crystal......
