[Fire bomb (d): Consume 100 magic points and attach a fire bomb to the target. The fire bomb will cause the target to suffer continuous fire damage. After the target receives five fire damage, the fire bomb will be destroyed.

Detonate, causing a range explosion. The current continuous fire damage is 10 points per second, and the range explosion damage is about 103 points. The spell damage will increase to a certain extent as the caster's intelligence and spiritual attributes increase]

...

The description of Fire Bomb is longer than the previous skills, but it is a solid D-level skill.

When this skill was developed, Yi Shen was actually a little confused.

Although in the display of spell research, you can obtain skills and attributes through specialization, he was really just preparing to break down some garbage to clean up the battlefield, and unexpectedly, he was given a big gift directly.

"Or AOE skills?"

Seeing the description of the skill, Yi Shen couldn't help but raise the corner of his mouth. Although he was already using the fireball skill very smoothly, if he could have a range of skills, it would definitely be a powerful tool for clearing out monsters!

The price of D-level skills in the market, even the most rubbish ones, starts with a few thousand contribution points.

And if it's an offensive range skill, if it's put up for auction, it wouldn't be surprising if it fetched tens of thousands.

Such a skill was actually obtained by Yi Shen for nothing at level 3. This made Yi Shen become more and more fond of spells and specialize in this lottery machine skill.

...

With the fire bomb, Yi Shen has more confidence in cleaning up this monster group.

He slowly approached the edge, then found a lone sand dune bug, and directly attached a fire bomb to the target.

After testing, the release range of the fire bomb is about 20 meters, which is much closer than the fireball technique.

But after Yi Shen released it, the magic power gathered directly without any trajectory, adding flames to the target!

The dune worm was still a little confused when it was attacked, and it hurriedly explored the underground of the dune.

But in Yi Shen's field of vision, the Dune Worm was losing blood every second!

"-10..."

"-14..."

"-13..."

"-13..."

"-11..."

"boom!"

After five damage jumps, there was a roar in the area where the sand dune bug was located!

"-156!"

"-93!"

The last explosion, in addition to causing a critical hit, also caused another monster to lose more than 90 points of blood!

A small crater appeared in the central area of ​​the explosion. Yi Shen saw that the body of a certain sand dune bug had glowed, and it was obvious that it had been killed by himself.

Level 3 and 4 sand dune bugs themselves only had over 200 HP points. Yi Shen only used a fire bomb skill to kill them completely instantly, and it didn't understand what happened until it died.

There was another Sand Dune Worm that was also blown up next to it. Yi Shen once again attached a fire bomb to this one. The mana cost of the fire bomb was actually not small, but for Yi Shen who could use skills without any consumption.

To be honest, this is a completely unlimited range skill!

"boom!"

There was another roar, and another sand dune bug was also blown to the ground.

The only pity is that their bodies were completely damaged and had basically no value for reuse.

Yi Shen did not collect the loot immediately.

Because after the two roars, other monsters were already approaching here.

Even though Yi Shen was confident enough in his output ability, he still didn't want to be surrounded by these monsters without any defensive equipment.

Finding a suitable area, Yi Shen began to fire bombs on the dune bugs and snow snakes one by one.

Some monsters have discovered Yi Shen's whereabouts and want to rush over and attack him.

But with the sound of explosions, they could only leave this world peacefully one by one.

...

[Ding, your level has been upgraded to lv4, and your attributes have been enhanced to a certain extent]

[Strength 2, Agility 2, Intelligence 4, Endurance 2, Spirit 3]

.....

This upgrade is much faster than before, but it does not have the enhancement effect of the Spell Heart, it is just an ordinary level upgrade.

Moreover, after cleaning up the battlefield, all spells were studied. Apart from a slight increase in intelligence, no other skills appeared.

A little disappointed.

But it's understandable.

After all, today's harvest is enough. If a powerful skill comes every few minutes, the system will probably treat it as a bug and deal with it.

After cleaning up the monsters outside the cave, Yi Shen decomposed most of the materials, leaving only a level 4 wristband to wear on his body.

The attributes of the wrist guards are not very good, only 2 points of physical bonus, but it is still better than nothing.

Generally speaking, there are two ways to wear equipment that can be put into the inventory.

After one meets the wearing conditions, it can be directly embodied on your body.

The other is that the wearing conditions have not been met and can be worn manually on the body, but it will not have the effect of increasing attributes.

The wrist guard belongs to the former, and when it is embodied on the hand, it actually has a bit of a sci-fi feel.

These caves are not big and can only be said to be the nests of sand dune bugs and snow snakes.

After cleaning everything in the den, he only found about twenty scattered monsters.

Fortunately, Yi Shen had already penetrated deep into the bone pile, and there should be many dens like this. He released an acceleration skill for himself and continued on the journey of spawning monsters.

...

Pile of sand bones.

In addition to Yi Shen who is tirelessly hunting monsters, there are actually other explorers.

Some explorers are here to gain experience, some are here to practice combat, but some are actually here for the materials.

After all, the number of slots in the inventory is limited. Even after killing a large monster like a snow rabbit, it is difficult to move the body and materials.

And small monsters like sand dune bugs and snow snakes can transport a lot on each trip.

There are many such piles of sand bones in the snowy desert. Those close to the strongholds even have organized teams to hunt them.

Therefore, at a place not far from Yi Shen, two figures appeared at this time.

The two figures were both carrying a large bag and were moving slowly along the wall of the bone pile. They were not cleaning up the monsters, but were also looking for something.

"Sister Qing, are you sure you can make more than 500 contribution points a day in this place?"

Among the two figures, the girl with short hair at the back expressed her doubts.

"Um."

"Now is the egg-laying period for sand dune bugs. If we are more efficient, five hundred contribution points a day will definitely not be much."

"The skins of sand dune bugs and the venom sacs of snow snakes can be sold at a good price, and their bodies are small in size. We can put dozens of them in a bag and sell them. We can earn at least more than 100 contribution points in one trip.
