The night is gradually deepening, and every house is closed to see the lights, only the orange street lamps emit a faint light, which is a little drowsy on the ground, giving people a sense of tranquility and depression.

Tengchong's main tourism and gambling stones, the two major industries are the economic pillars of Tengchong, there is no pollution of heavy industry, Tengchong's air is not polluted, so the air is fresh and the sky is blue.

Even in the middle of the night, you can see the moonlit clouds and shining stars, giving you a feeling of relaxation.

Such a beautiful scenery cannot be seen in Pengcheng.

Liu Chengfeng stood alone in the moonlight, frowning and thinking as he looked at the misty hot spring. There were two books at his feet, the top of which was the wood-based spell Turf Thorn, and the bottom was a copy of the Ice Chill.

Among them, the Turquoise Thorn has already turned two pages, indicating that Liu Chengfeng has studied it and seems to have encountered a problem.

"What went wrong? I have mastered all the tricks?" Liu Chengfeng muttered to himself, not to mention how depressed he was at this time, while everyone was sleeping, he sneaked out to learn spells, but he had been stuck here for more than an hour, but there was no progress.

His mental method, exercise route, and fingertips were obviously right, but unfortunately there was no reaction.

After removing the spikes, Liu Chengfeng patiently began to study the ice cone. Ice Cone is a water-based spell, and it's not very deep.

There has been a prototype of an ice cone in martial arts novels, yes, you guessed right, in Jin Yong's martial arts novels, there is a vulture palace, and the vulture palace has a unique secret weapon called life and death charm.

The principle of the life and death charm is very simple, that is, the palm of the palm takes the water and the true qi is retrograde, so that the true qi is several times colder than the ice, so that the life and death charm will be made, and then excited out with internal force, which can be fought alone or in groups, making people unable to prevent it.

The nature of the ice charm is similar, strictly speaking, it is more advanced than the life and death charm, the life and death charm is the palm of the water into ice, while the ice is the air water into ice, its technique is more superb, the changes are more unpredictable, people are simply defenseless.

It's hard to imagine how mortals can resist this spell when they are successfully cultivated.

After knowing the principle, Liu Chengfeng's aura reversed, took water in the air, and made ice picks. At this moment, Liu Chengfeng was a little nervous, he was afraid that the ice cube cone would be the same as the Turbulent Wood Thorn, and he would not react at all when casting the spell.

However, his worries were unnecessary, and not long after he cast the spell, there was a wave in the air, and this fluctuation gave people a soft feeling, like water.

The next moment, the temperature in the air dropped suddenly, almost to freezing, but Liu Chengfeng, who was casting the spell, didn't feel it, he just felt cool.

Immediately afterwards, several ice spikes appeared out of thin air in the air, the ice spikes were about the thickness of a finger, the front section was sharp and the tail end was thick, and Liu Chengfeng could even see the sharp part bubbling with a trace of cold.

The ice spikes stayed in the air in a disorderly manner, which obviously violated common sense, but Liu Chengfeng himself was a cultivator, and he could still be shocked by this kind of thing?

Now it's just a matter of waiting for him to give the order, order the icicle to point where to hit.

Thinking of this, Liu Chengfeng was excited but still pretended to be serious, and spit out lightly in his mouth: "Go to ......"

As if pulled by the qi engine, the chaotic ice picks shot away in the same direction, and the speed was so fast that the naked eye had no time to catch it, and Liu Chengfeng was dumbfounded.

With such a fast speed, if it hits a person, it will not be able to resist the attack of the ice Lingqi at all.

It's a pity that no one will experiment on Liu Chengfeng, and the ice spike shoots into the hard stone wall in the blink of an eye, and then makes a few muffled snorts before disappearing.

Liu Chengfeng hurriedly walked over and squatted down to check, he found that in addition to a little water stains on the surface of the stone wall, there were obvious punctures, which showed that the striking strength of the ice spikes was not bad, and if it was used against people, it was even better than a gun.

This time Liu Chengfeng was very excited, this is much more windy than the fire bomb technique, and it is much more powerful than the fire bomb technique, this is the spell he hopes to have!

Because he was too excited, Liu Chengfeng couldn't help but use the fire bomb technique, wanting to compare it with the ice ling.

As soon as the fire bombing technique was cast, five vigorous small flames appeared from the fingers, and the small flames were blue and yellow, swaying on the fingertips, like dancing.

Liu Chengfeng was stunned for a moment, is this a fire bomb technique?

Since I learned the art of fire bombing, it seems that the power has never surpassed that of today, what is going on?

"Go to ......" Liu Chengfeng waved his palm, and the five vigorous flames immediately detached from his fingers, and then shot towards the ground.

During this period, the flames were not affected by the speed, let alone extinguished, and when they fell to the ground, they seemed to want to get into it.

However, the flames did not penetrate into the ground, but only left five blackened black spots on the ground, and then extinguished.

Liu Chengfeng squatted in place and thought for a while, then turned his head suddenly, staring at the hot spring with bright eyes, and after a long time he muttered to himself: "I understand, no wonder Tumu Thorn didn't react......"

Undoubtedly, it is not that the fire bomb technique is powerless, but that there are limitations in the field.

When I first learned the art of fireball, I could barely emit a small flame and when it was launched, it seemed that even a gust of wind could easily extinguish it.

And now, what is the place at the foot of Liu Chengfeng? It is an active volcano, so the fire element power is abundant, and the fire bomb excites five at once, and it is extremely vigorous, powerful and powerful.

In addition, the ice sauce originally contained moisture in the air, but now it is next to the hot spring, so it is naturally a matter of course.

In the Geopark, although there is artificially cultivated vegetation, it is not vigorous, especially around the active volcano, and there is no grass, and it is strange to be able to cultivate successfully.

In short, no matter which system of exercises you practice, you have to find the right material to get twice the result with half the effort.

For example, the fire bomb technique is to find a place with abundant fire power, let's not talk about finding an active volcano, this kind of place is hard to find, do you have to lead people to the volcano when fighting?

It's a bit impractical!

From beginning to end, when Liu Chengfeng practiced the fire bullet technique, it was always at night.

And in the middle of the day, the time when the fire element power is most abundant is naturally during the day, especially at noon.

The sun is the essence of fire, and during the day, especially at noon, it can naturally achieve twice the result with half the effort, and it is more powerful.

Ice cones, you must look for a place with a lot of water, preferably a place like a river or lake.

As for the stinger, it is natural to find a place with a lot of plants, and in general, in the city, there is a place with greenery that can meet this requirement, and only in a place like an active volcano where there is no grass, can not use the thorn.

Thinking about the joints, Liu Chengfeng was relieved in his heart, but fortunately it was not his own problem, and he adapted measures to local conditions!
