Heavenly Thunder Son, a one-time treasure refined by the Heavenly Tribulation, this kind of treasure refining is extremely difficult, it must be refined by the person when he crosses the tribulation, and it must be refined in a short time during the tribulation.

In this way, the heavenly thunder has become a rare one-time treasure, and it has also become one of the life-saving treasures refined by the major forces.

This is very difficult, if someone else crosses the tribulation, if you go to refine the heavenly thunder, you may cause a series of heavenly tribulations if you are not careful, so you generally will not refine the heavenly thunder when others are crossing the tribulation.

In this way, refining the Heavenly Thunder Seed can only be refined by the Tribulation Person, and this makes it more difficult to refine the Heavenly Thunder Seed, after all, when the Heavenly Thunder Seed is crossed, it is already very hard to deal with the Heavenly Tribulation, who still has the kung fu to refine the Heavenly Thunder Child.

This makes it impossible for most people to refine the Heavenly Thunder Seed during the Tribulation, only the strong people of the big force can have the energy to refine the Heavenly Thunder Seed during the Tribulation, and if you want to refine the Heavenly Thunder Seed during the Tribulation, you must also be proficient in refining weapons, which increases the difficulty of refining the Heavenly Thunder Child.

In a word, various reasons make it difficult to refine the Heavenly Thunder Seed.

The general Tianleizi is divided into four levels, the lower grade, the middle grade, the upper grade, and the best four grades, of which the lower grade Tianleizi is refined by the monk Yuanying Tianjiao, and the power can be compared to a cost-effective master.

The middle-grade Heavenly Thunder Seed is refined by a monk during the Tribulation Period, and its power can be compared to a blow from the Heavenly Immortals, and the high-grade Heavenly Thunder Seed is refined by the Holy Heavenly Tribulation, and its power can be compared to a blow from the Dominator.

As for the higher Superb Heavenly Thunder Son, it was refined by the powerful cultivators of the Endless Void with a special method to lead down the Thunder Tribulation, and its power was large and small, the small power could be compared to the powerful blow of Chaos, and the great power could be compared to the powerful blow of the Pseudo-Eternal Dao Monarch.

Although the best Heavenly Thunder Son is not refined by the Heavenly Thunder of the Tribulation, but specially introduced by the monk, it does not mean that it is easy, first, this kind of thunder guidance secret method is very rare and dangerous, and second, the difficulty of refining.

The higher the level, the higher the difficulty of refining the Heavenly Thunder Seed, and it is not difficult to refine the best Heavenly Thunder Seed that is comparable to the first blow of a Chaos-level master, but the difficulty of refining is very difficult compared to the Heavenly Thunder Seed that can be compared to the first blow of a pseudo-eternal level master.

Generally, big forces, this level of Tianleizi will not refine a lot, at most a few as a killer weapon, or as a talisman for younger generations, there will definitely not be many, which is why Li Yuanfang guessed that many forces were involved in this assassination.

"It's not going to die!"

Li Yuanfang was assassinated, and he was noticed by the powerhouses who paid attention to the endless void here for the first time, and felt the strength and madness of the assassin, they all sweated for Li Yuanfang, originally they thought that under this kind of assassination, Li Yuanfang would definitely not be spared.

But they didn't expect that such an assassination would not be able to do anything to Li Yuanfang, and they once again felt Li Yuanfang's power, and a strong pressure came, but under the comparison of Li Yuanfang's unfathomable cultivation, they all felt the pressure.

However, although Li Yuanfang was not injured, he was a little embarrassed, which was nothing for Li Yuanfang, but it was different in the eyes of those who cared.

Li Yuanfang was embarrassed, what does this mean, it shows that Li Yuanfang is not invincible, he can be defeated, this gives the other powerhouses of the Endless Void a chance, a hope, a chance and hope to defeat Li Yuanfang.

At the same time, this assassination was just a prelude, the real assassination had just begun, just when Li Yuanfang was scolding in his heart and embarrassed, in an instant, four powerful attacks came towards him.

"Come back!"

Looking at the four assassins who attacked him from all sides, Li Yuanfang was a little stunned, wouldn't it be another suicide attack, this time I have to be careful, Li Yuanfang thought in his heart, but he didn't dare to be careless.

Even at this time, Li Yuanfang was ready to flee at any time, and once these four people blew themselves up, Li Yuanfang was ready to escape.

The attacks of these four assassins could no longer be regarded as sneak attacks for Li Yuanfang, but these four assassins were not prepared to kill Li Yuanfang by surrendering, and the attacks of the four assassins blocked Li Yuanfang's various retreats.

At this time, Li Yuanfang can be said to be attacked from all sides, no matter how he dodges, he will inevitably receive a lot of attacks, and even Li Yuanfang knows that if he dodges, he will definitely be injured, you must know that the attacks of these four assassins are even stronger than the attacks of the assassins just now, Li Yuanfang feels a little threatened.

Although it was only a little threat, Li Yuanfang did not dare to be careless at all.

"Howling ......"

With a loud roar, Li Yuanfang saw this situation and was ready to resist without hesitation.

"A bunch of rats, sent to death!"

Li Yuanfang scolded, and the sword in his hand began to swing, and in an instant, Li Yuanfang's sword began to spin.

"Sword Qi Storm!"

In an instant, Li Yuanfang's sword quickly formed a storm of sword qi under his dance, and countless sword qi spread out in all directions, and each of the four assassins was attacked by countless sword qi.

"Awesome!"

In the midst of the exclamations all around, countless sword qi attacked towards the four assassins, and the assassins on all sides had to dodge or defeat these sword qi at this time, otherwise they would be killed by Li Yuanfang's sword qi before they really attacked Li Yuanfang.

It's just that Li Yuanfang's sword qi is so simple, the reason why the assassin is an assassin can only show that the assassin's attack and advance are strong, but it does not mean that his defense and frontal combat are strong.

Therefore, in the face of Li Yuanfang's sword qi, the four assassins were immediately in a hurry, and even two assassins were attacked by the sword qi without paying attention, and then caused a chain reaction, causing the two assassins to be hit by Li Yuanfang's countless sword qi and hung up after letting out a miserable scream.

The remaining two assassins lost the long-gestation surprise attack, and where was Li Yuanfang's opponent, they were quickly killed by Li Yuanfang, who had his free hand.

This time, the four assassins did not carry the Heavenly Thunder Son, but the last two assassins also wanted to blow themselves up, but before they could do so, they were killed by Li Yuanfang, who had already noticed the situation.

"Kill!"

Just when Li Yuanfang killed these four assassins, before he could breathe a sigh of relief, another wave of assassins came to attack, and this wave of attacking assassins was eight people, twice as many as just now, and the powerful attack, even Li Yuanfang had to concentrate on it.

However, although these assassins are powerful, they have lost their ability to advance How are they Li Yuanfang's opponents, they were killed by Li Yuanfang just by looking at each other, seeing this situation, the powerhouses of the Endless Void saw Li Yuanfang's strong combat power for the first time.

In the frontal battle, these assassins were completely crushed by Li Yuanfang, and there was no room to fight back.
