A real magic weapon not only needs the skills of a supreme casting master, nor does it only need the best casting materials, but also needs to be recognized by heaven and earth.

This is what Railway Joe wants to tell Chen Feng.

"Therefore, you must now carry the sword to face the test of the heavens, and only you, the owner of the sword, are qualified to carry it. and go through this test with it. ”

Railway Qiao smiled and handed the sword back to Chen Feng.

"The test of the thunder? I'm looking forward to it. ”

Chen Feng thought about it, and took the sword with his hand, and as soon as the sword was in his hand, it had a completely different change from just now.

Originally, after sucking Chen Feng's blood, Chen Mingjie was dark reddish-brown, but as soon as Chen Feng held the hilt of the sword, the whole sword immediately emitted a brilliant light, dazzling red light, and dazzling golden light, which reflected the magma under him, and also bloomed with blazing heat.

Carrying the sword, he walked out of the cave, and sure enough, the whole world outside had changed greatly.

Above Chen Feng's head, in the past three days, the dark clouds that were like ink smudged slowly gathered together and closed in one place, among which there were lightning and thunder, and there were thunder dragons rolling.

The vast coercion of heaven and earth, when Chen Feng appeared, he pressed towards him completely, to be precise, towards the sword in his hand, and launched a coercion.

The sword has a spirit, and when he felt the opposition from the sky, he trembled without showing weakness, and the light on the sword body was even more dazzling, and it seemed that he wanted to compare with the heavens.

Bang!

Good fellow, God seems to be angry, the dark clouds above him are darker, the thunder and lightning are stronger, and the speed of gathering is faster.

And in its center, a bright light that could not be avoided, with countless thunderbolts began to surround it.

"Are you going to start?"

Facing the power of the sky, the thunder and lightning were as vast as the sea, Chen Feng felt the momentum in the sky, and muttered to himself, but there was no fear at all, on the contrary, he was a little looking forward to what would happen next.

It's really exciting...... Chen Feng thought in his heart, and his eyes suddenly lit up, but it was the thunderstorm that fell the first thunderbolt.

This thunder and lightning is only the first reason, so it is not so terrible, but it is still the thickness of a child's arm, and if ordinary people are hit, at least it will be a serious injury.

However, with Chen Feng's current cultivation, he didn't need to care too much, he just waved the sword in his hand lightly, and the sword body slashed through the air, just hitting the thunderbolt that was splitting down, and without delay, the thunderbolt was completely split in two.

The first thunderbolt is perfectly resolved!

"If this thunder tribulation is at this level, it is inevitably a little too weak, or is this sword in my hand not enough for you to pay attention to?"

Chen Feng looked at the sky with more expectant eyes, where a more intense thunder and lightning were converging at this time.

Bang!

The second thunderbolt slashed down, which was twice as thick as before, but Chen Feng still split it easily, and the sword in his hand was unscathed, and even conveyed bursts of joy and anticipation to Chen Feng.

"In that case, then you can go."

Chen Feng felt the expectation in the sword, smiled, stretched out his hand and threw the sword in his hand into the sky, and used the sword technique, controlling the sword to fly in the sky, directly towards the third thunder that had not yet fallen, as if it was going to smash the yellow dragon.

The thunder and lightning also sensed this, and no longer stayed, perhaps for the sake of the majesty of the heavens, and went straight down.

The thunderbolt and the sword clashed in the air, and just like the first and second thunderbolts before, the third thunderbolt was easily resisted.

This provocative act seemed to infuriate the thunderstorm even more, and the thunder and lightning in the sky became even more intense, as if something was brewing, a great terror.

After that, the fourth, fifth, and sixth thunderbolts, Chen Feng felt very relaxed, he only needed to control the sword in the air and split these thunderbolts.

However, when it comes to the seventh thunderbolt, it is completely different.

The seventh thunderbolt alone, not to mention the degree of condensation, its width alone is already equivalent to the sum of the previous six thunderbolts, and at this moment, even Chen Feng had to be cautious.

"Hurry!"

With a light snort in his mouth, Chen Feng held the sword technique in his hand, and it was actually the first time that he used a sword technique other than the sword technique.

The sword was in the air, and it immediately showed a different power from before, and it exuded a red glow, as if a black and red flame was burning in the air, and it was like a meteor that slipped from the sky, colliding with thunder and lightning. In the end, it was the meteor that was better and fell smoothly into Chen Feng's hands.

Chen Feng looked at the sword in his hand and observed it carefully, but found that the sword was slightly different from the beginning.

If you say before, when you first got it, although the sword showed a different power, but, in Chen Feng's opinion, there were still some artificial traces, which were not very perfect.

However, after a few Heavenly Thunder Tempering, this sword became even more perfect.

To put it simply, it looks more natural, as if there was a sword between heaven and earth, and not forged by someone.

At this time, the eighth thunderbolt slashed down, and the power was already twice that of the seventh thunderbolt, and it was even more heavy and majestic.

In the face of such momentum, ordinary people are afraid that they can't even stand on their feet at this moment.

However, Chen Feng was not in a hurry, a smile appeared on the corner of his mouth, as if he was quite satisfied with the current sword, and said to himself: "Okay, let me see your other abilities." ”

As he spoke, he swung a sword at the eighth thunder tribulation through the air far away.

A magical scene appeared, the sword that was originally only three feet long, but at this time, it turned into thousands of small flying swords like fragments, and began to crack down along the patterns of the sword's body, one after another, towards the eighth thunderbolt.

And Chen Feng said softly in his mouth at this time:

"Ten Thousand Swords!"

With the frenzied surge of true qi in his body, thousands of small flying swords, like an order, began to send out the most courageous charge towards the eighth thunderbolt.

Each sword could easily kill an Innate Realm cultivator, and the power of tens of thousands of small flying swords of this power gathered together was already quite terrifying.

At this time, in the sky, under the dark clouds, there were countless flying swords that emitted a tiny red light, and like moths to a fire, they began to attack towards the thick thunder and lightning.

Chen Feng was trying his best to control these thousands of small flying swords, striving to make each flying sword come into contact with thunder and lightning, so that its whole body was fully tempered by thunder and lightning.

His intention in doing this was naturally not just to simply resist this eighth thunderbolt, but to let the power of this thunder and lightning fully "nourish" the sword.

After the tempering of the previous seven thunderbolts, the sword was naturally the same on the outside, but the inside of the sword was still a little less meaningful in Chen Feng's opinion.

That's why he suddenly used the Ten Thousand Sword Technique to activate the special effect of the sword, turning it into thousands of sword blades and resisting the eighth thunderbolt at the same time.

The purpose of this is nothing more than to allow the entire sword to fully receive the nourishment of thunder and lightning.

Of course, you should also be careful in this process, in case because of your own lack of caution, if any of the small flying swords suffered from unbearable thunder and lightning power and shattered, then Chen Feng could only hide in the toilet and cry bitterly.

But luckily, everything went well.

The hardness and tenacity of the sword were also beyond Chen Feng's imagination, it actually really resisted the eighth thunderbolt, and now, only the last thunderbolt remained, and this was also the most important step in the entire thunder tribulation.

According to Railroad Joe, in their foundry industry, it is called a godsend!
