accidentally got the song of spiritual energy, which made Lu Chengfeng's good mood last for a day.

However, after feeling the activity of the fighting spirit in his body, Lu Chengfeng had to face a fact. That is, after filming the Song of Psionic Energy, the money left on him was no longer enough to buy an energy storage gem. This means that the route to obtain gems through the trading house is blocked, and Lu Chengfeng can only consider doing it himself.

This requires him to find a target first.

The mercenary tasks that can be given to the storage gems are either too difficult or completely unsuitable for him to complete alone. Lu Chengfeng's best choice right now is to kill the right demonic beasts and obtain their magic cores. Considering that the quality of the Magic Core is generally inferior to that of the Storage Gem, this goal must be carefully chosen.

For two days, Lu Chengfeng never found a suitable target.

But at this time, a new D-class mission from the mercenary guild caught his attention.

In the Thunder Heights town on the edge of the endless forest, the weather has changed very strangely in the past month, and there are frequent thunderstorms. As a result, the town of Thundering Heights issued a commission to the mercenary union in Kaiyang.

The reward for this quest is very mediocre, and the small town that is not rich only scrapes together 500 gold coins.

A mission with unknown information and a reward of only five hundred gold coins is obviously not enough to impress those masters. And the weaker low-level martial artists were worried about whether they could deal with a fourth-order demonic beast. So, in their hesitation, Lu Chengfeng snatched the task.

It doesn't matter what the mission reward is, the key is that after taking the mission, Lu Chengfeng can get the assistance of the Thundering Highlands Town, as well as more detailed information.

Undoubtedly, Lu Chengfeng had his eyes on the magic core of this fourth-order thunder beast.

Compared to the acceleration of the wind crystal, the magic core with the lightning attribute can add the lightning attribute to the lightsaber, paralyzing the enemy's movements to a certain extent. One is to speed up your own team, and the other is to slow down the enemy, both of which actually work in the same way. According to a few pieces of information he had gathered briefly, thunderstorms were frequent in the vicinity of the Thundering Heights themselves. The magic core of the nearby thunder-type demonic beast should be quite pure in quality, and it is a spare sword-forging material worthy of his consideration.

So, half a day later, Lu Chengfeng appeared in the town on the thundering heights.

It's a small town, but it's not much bigger than an ordinary farmstead. Since most of the young and middle-aged people went to Kaiyang City to beg for a living, the garrison strength of the town was really limited. There are only seven or eight people in the garrison, and the average strength is only second-order. To put it mildly, Lu Chengfeng could knock them all down with one hand.

"Who are you?"

Probably thinking that Lu Chengfeng was very young, he had no equipment on his body, his weapons were very average, and the only ring was even more gray (re-disguised), and the faces of several guards in charge of greeting him were full of suspicion. They made it clear in their mission requirements that the opponent was likely to be a fourth-order thunder beast. In the face of such an enemy, why do you need a mercenary team, or a fifth-order master?

An ordinary third-order swordsman came alone, didn't he really come to send him to death?

Lu Chengfeng naturally saw the suspicion in their hearts, but it was useless to distinguish it, so he could only pout. After all, if it weren't for the rebirth, his appearance would not be convincing at all.

After a brief rest and understanding the situation, Lu Chengfeng quickly set off and appointed a person to lead the way. However, the guard who was named was full of reluctance, feeling that this trip was unlucky, but he couldn't help but go, so he had to prepare for a while, and slowly hung behind Lu Chengfeng and set off.

At this moment, on a sunny summer day, which was supposed to be hot and dry, a thunderbolt suddenly appeared.

With the rumbling thunder, clouds gathered in the sky, and then a sudden heavy rain fell. The young guard assigned to Lu Chengfeng to lead the way was probably commonplace, and he said to Lu Chengfeng: "Look, it's such strange weather, it's been like this for the past month. ”

"It's a strange ...... indeed"

From the thunder and lightning in the clear sky to the sudden heavy rain, it only takes two or three minutes before and after. The vicinity of Kaiyang can be said to be like spring all year round, and even if there is heavy rain in summer, it will never be so abrupt. This extremely abnormal climate allowed Lu Chengfeng to determine the identity of the monster. Only powerful thunder-type demonic beasts, when they uncontrollably release their magic power in their bodies, will interfere with the nearby climate and form such a sudden thunderstorm - of course, this also has a lot to do with the special climate of the Thunder Heights town itself.

Anyway, judging from the strength of the lightning, the strength of this thunder beast is quite not weak!

Although he had a little doubt about whether he could kill that monster, Lu Chengfeng was more undoubtedly excited. In this way, the demon core bred by the demonic beast will definitely be able to forge an excellent thunder attribute lightsaber.

The heavy rain did not stop until two o'clock in the afternoon, and seeing that the weather was clear, at the urging of Lu Chengfeng, the guard led him into the mountains and forests near the thundering heights. According to the guard, the monster suspected to be a fourth-order thunder beast was at the top of the mountain forest, less than ten kilometers away from them.

It was precisely because it was not far away that the people in the village would be so worried, for fear that the fourth-order demonic beast would suddenly rush out and hurt people. Because with the guards in the village, it is impossible to stop the wreaking havoc of that demonic beast.

All the way to the silence of the deep.

After the heavy rain, the mountains and forests were wet, and the leaves of the superba and birch trees more than ten meters high were dripping from time to time. At this time, entering the mountains and forests is obviously not the best choice. For this reason, the guard chattered all the way. There is no shortage of complaining. But Lu Chengfeng had his own ideas, so he didn't pay attention to this young man at all, and just followed him all the way to the destination area.

Here, Lu Chengfeng saw some familiar traces.

"Kobold?"

In addition to the fourth-order thunder beast on the top of the mountain, there should be a group of kobolds nearby. These dwarf monsters are common in the Endless Forest, and there's nothing unusual about them here. In order to prevent being interfered with by these kobolds when dealing with fourth-order thunder beasts, Lu Chengfeng decided to deal with them first.

It's just that before Lu Chengfeng took the initiative to find the door, several kobold warriors had already found him in trouble.

Since the initial rank was too low, his strength had improved significantly, and now Lu Chengfeng could see obvious progress every day he passed. When he entered the Endless Forest before, these most ordinary kobolds couldn't help him. Now, with the help of the song of spiritual energy, these kobolds are even more dishes delivered to the door.

A few sword lights went down, and another Earth Crack Wave Sword was added, and Lu Chengfeng easily solved them.

This speed made the guard who led the way a little impressed. However, he still didn't believe that a third-order swordsman could defeat a fourth-order thunder beast. Even in the next battle, Lu Chengfeng killed several kobold spellcasters who had initially mastered the elemental power one after another, his attitude never changed.

He can also kill kobolds, which doesn't mean much.

"It should be right up ahead. ”

Seeing that he was about to reach the top of the mountain, the guard who led the way stopped and refused to continue on his way.

"Okay, then you wait here for now. ”

Lu Chengfeng knew that he couldn't trust himself, and he didn't force it, he just asked him to wait here, and walked up alone.

Five minutes later, he saw the fourth-order thunder beast on the stone platform on the top of the mountain. It was an upright gray-white dwarf-like beast with a single horn on its head and powerful thunder and lightning energy all over its body. Maybe there had already been mercenaries who had already defeated it before, and Lu Chengfeng saw a short sword with dried blood stains on the top of the pile of tattered pieces collected behind it.

Since it was included in the Heavenly Wind Empire's Mutant Warcraft Atlas, after seeing it with his own eyes, Lu Chengfeng immediately confirmed its identity.

This powerful fourth-order demonic beast has spell damage beyond imagination!

Fortunately, he was prepared.

Ordinary warriors like to wear heavy metal armor and hold a giant sword, which is quite amazing in both defense and destruction. However, this kind of equipment is very useful when dealing with other magical beasts, and it is self-defeating to use it against thunder beasts. The metal's excellent electrical conductivity will make its lightning spells exert one hundred and twenty percent of their power.

It's the same with the Iron Sword.

If he used a lightsaber at this moment, Lu Chengfeng would not have any scruples. Unfortunately, he used an ordinary steel longsword, which required him to handle the longsword to a certain extent. Before starting the battle, Lu Chengfeng took out the salamander potion prepared in advance from his backpack. This potion briefly adds energy to the weapon, turning it into a fire-based magic weapon.

After being covered by a layer of fire attribute energy, this sword will no longer easily provoke thunder and lightning.

The salamander potion is red all over and is a little warm to the touch. Other than that, it doesn't look like anything special. However, when Lu Chengfeng carefully applied the salamander potion evenly all over the back of the sword, and after it came into contact with the air, the originally ordinary stainless steel long sword suddenly became hot, and the whole body burned with crimson flames.

Lu Chengfeng waved it in satisfaction, and then killed the thunder beast that had already noticed the abnormal movement here.
