The bow was made, and the next was the arrow.

Li Changfeng has a lot of brains for this arrow, and the shaft of the arrow is made of iron ploughshare, needless to say.

Although iron ploughwood is a rare and precious tree in the mortal world, he is in the inaccessible mountains, and there are not many others, and all kinds of wood can be used casually without money.

One person hugged such a thick iron plough wood tree, and directly cut down two roots and dragged them home.

Li Changfeng used a kind of white big bird feathers, and for these feathers, he grabbed big birds all over the world and plucked them. After these big birds went back, they were frightened, and the meeting unanimously agreed that from now on, the valley where Li Changfeng lived would be classified as a forbidden area!

The bow and arrows are not very powerful, but they are all pointed at the arrows. He decided to use the method of grenades, making a crash-and-blow type.

As for the raw materials, Li Changfeng reluctantly dismantled the three grenades, and used the fiery stone powder and dark iron flakes inside to process them into arrowheads.

The arrow is divided into two sections, conical in shape, hollow, and filled with powder. The back half is made of ordinary fine iron, but the front is made of a little dark iron to increase the penetration.

The bow and arrow were formed, and the effect was not bad, and the big snake tendon was strong in elasticity, and it could penetrate the tree body by shooting 200 meters. After the explosion, the tree was blown into a bowl-sized hole. It is more than enough to deal with ordinary people, and it is more than enough to deal with monks...... I guess it's no fun.

Archery is a technical job, even if you are a cultivator, you have to practice to get good results.

As a monk, there are also benefits, strength, stamina, stability of the hands, clarity of the eyes......

These are the foundations. On such a basis, if you still have to practice a good archery, it is really - go home and wash and sleep. Remember, sleep on the floor, too stupid people only deserve to sleep there!

Li Changfeng can sleep in a bed.

He made some ordinary arrows for practice, and in five days, he could shoot the target red heart at a distance of 150 meters.

With more exercise, it is estimated that it is very possible to pierce the birds in the sky. It's a pity that those big birds regard this place as a forbidden area, and there is not even a single bird feather in the sky, so it is impossible to try your hand at it!

......

Runes.

The matter of weapons came to an end for the time being, and Li Changfeng's eyes turned to the runes again.

There are too few spells, no attack spells. This is a thorn in his heart, which makes him uncomfortable all over his body - what is strong, it is not as strong as himself. Even children know this.

The problem is, I don't have to learn! I have to study on my own.

It's not blind research. He asked the system, and according to the system's analysis, spells have a deep relationship with runes. After the system has been upgraded to another level, it has been able to parse simple runes according to some conditions.

Like now, Li Changfeng was staring at the skin of the pig-faced demon beast. The pig-faced demon beast's head remained relatively intact when it died, and what impressed him deeply was the scene of the demon beast unleashing the fireball spell.

The part where the spell was released was the position on the head and in front of the nose, and Li Changfeng was staring at this position, he wanted to find out if there were any runes here.

If you can research some results, you might be able to learn a fireball spell.

Speaking of this fireball technique, Li Changfeng was quite resentful: looking at the condensation of elements in front of the pig-faced demon beast's mouth, in the blink of an eye, a fireball was shot, which exploded the enemy, and the person turned over on his back, holding his head and running away. What a chic and crisp way to be!

Looking at himself again, he finally condensed a flame between his fingers, threw it out, and dissipated directly into the wind. What a miserable and desolate it is!

It's all fire, why is the gap so big?!

The system is rapidly computing, and this situation requires the consumption of vitality, and there is still a lot of vitality consumed. Li Changqing had to stop and meditate every few hours to recover his vitality.

Whenever there is a little progress in the system, it is also necessary to stare at the pigskin's mouth for a while from time to time, which is to carry out physical comparison and in-depth analysis.

Five days later.

"The incomplete analysis of the pig's mouth demon beast fireball rune has been completed, and the results are as follows......"

The sound of the system finally sounded, and Li Changfeng was like a heavenly sound. This scientific research work is really not easy!

According to the results of the system's analysis, he understood why there was a huge gap between the two fires:

Pyrotechnique is a simple spell, and there is only one type of rune used, which plays the role of gathering fire elements.

The Fireball Technique, on the other hand, is a more complex spell that consists of three types of runes:

One is the rune that gathers the fire element, and the role is needless to say, Li Changqing named it "Gathering Fire Rune".

The second is the "Compression Rune", which requires a large amount of compressed fire elements to reach a certain concentration in order for this flame to become a fireball.

The third is "release runes", after the fireball is formed, it is not simply thrown out, it is too slow, and it is not safe, there is a special set of launching methods, which is to release runes.

This is also the only rune in the system that has not yet been fully resolved. Li Changfeng asked it to quickly analyze, and the system replied that the runes were too complex and lacked ability, and they needed to be upgraded again to complete the analysis.

Li Changfeng heard it with itchy teeth, and in the end he couldn't help it, so he pinched his nose and agreed to let half of the vitality come out to let it upgrade.

It takes a long time for the system to upgrade, and Li Changqing doesn't dare to try this fireball technique - the release rune doesn't come out, and the compression rune doesn't dare to try, if the fireball is compressed in his hand, but he can't release it, then he won't try his life!

After thinking about it, he thought of the refining weapon again, with this compression rune, could it be possible to press out fireballs to be used as bullets, if this was done, it would not be infinite bullets!

It's just that how do you launch it? You'll have to wait for the runes to be released. Come on, let's wait honestly.

Slowly and little by little, he had to advance, and the system had to be upgraded, which took too long, so he hit the idea to Juyuan Stone again.

The speed of Juyuan Stone's assisted cultivation is still very fast, as long as the problem of overflow is solved, it will not cause such a big waste.

Li Changfeng decided to use the method of wrapping to see if it would work.

The remaining materials in his hand were experimented one by one, and finally found that the green barium could wrap the Yuan Stone so that it would not overflow, the problem was that it was useless for cultivation, and the waste of Yuan Qi during cultivation was caused by the speed of absorption not keeping up with the speed of overflow.

Wrapped, only open a hole to let it release the vitality, the vitality is released along the opening, the problem is that the palm can't hold the yuan stone in all directions, and it can't absorb the vitality at all.

The experiment failed completely, and the people were honest.

......

Autumn is coming, and the trees in the mountains are beginning to show a depressed color. When the wind blows, the yellow leaves fall off, adding another layer to the old leaves that have accumulated under the tree.

The fruits of the various fruit trees began to ripen, and the branches hung heavily, filling the air in the forest with a rich fragrance of fruit.

Animals that need to hibernate begin the busiest part of the year – accumulating energy to survive the winter.

Herbivores stuff all kinds of grasses, leaves, twigs, and fruits into the stomach as much as possible. And the carnivores have also changed from the laziness of not hunting after they have eaten enough, and desperately turn all kinds of meat that they can see and eat into fat on their bodies.

When it rains, it is a lingering drizzle, endlessly scattered, taking away the heat in the air little by little. The coolness is getting deeper and deeper.

Li Changfeng is sweating now, it is a big sweat.

The sulphur-smelling air around him was dazzling, and despite the constant use of water mist, in the belly of this hot volcano full of fire elements, the effect of the spell was very limited, and before he could take a few more breaths to moisten his throat, the mist almost dissipated.

Extremely effective and versatile, it is currently the material that he values the most, and there is no one. In order to get a few more pieces of this thing, he hit the idea into the belly of the crater, the only place where fire stones are abundant.

"Just climb a little bit and hold on a little longer and you'll find it!"

Desperately cheering himself up, but his psychology is on the verge of despair. Climbing on the rock wall of the volcano, he could already see the red glow of the magma in the distance.

"You can't climb any further, you have to leave the physical strength to return!"

Unwilling to take one last look, Li Changfeng was about to admit defeat and go home, but as far as his eyes could see, he was suddenly stunned:

"Ubo?!"

He had been thinking about the fire stone, so he only paid attention to the red thing, but he almost revealed the silver-gray black platinum.

"Ubo and the fire stone are accompanied, it has appeared, will the fire stone be far away?"

Spirited, he returned to the top of the mountain to rest for a while, and then went down to the belly of the mountain with confidence. This time, you don't have to climb and look for it, just descend along the rope to the place where you found the Ubo.

On this day, he searched up and down here five times, and finally the emperor lived up to his painstaking efforts, allowing him to find five fiery stones and a black platinum.

Only then did Li Changfeng discover that black platinum is a more rare mineral than fire stone.
