In the face of the scorching lava, Lei Yu used the "Outline of the Five Elements to Crack the Law", and melted into the fire element, and the scorching heat disappeared, and the thunderstorm approached the magma, and in the magma, the lively fire element beat on its surface, so much, Lei Yu felt a burst of ecstasy in his heart, "I have to collect more of these lively fire elements today!"

While he was collecting the Lively Fire Elemental on a large scale, Little Stone exclaimed in surprise in his divine sense, "Red Flame Beast! Master, quick, quick, follow it." ”

Thunderstorm looked at it and saw a long-billed animal the size of a wild cat, walking leisurely at the bottom of the lava, looking for something in the lava, and from time to time taking something out of the raging magma.

"The Red Flame Beast likes fire crystals the most, there must be a lot of them hidden in its cave, the master can follow it to its lair, and he will definitely find a lot of fire crystals, which is much more convenient than you collect like this. ”

"Okay, then I'll go with it. The thunderstorm floated, and it was less than a few hundred meters away from the red flame beast, and the movement of the thunderstorm may have disturbed it, and as soon as it swung its smooth fur, it turned around and ran towards the bottom of the magma wall.

The thunderstorm that followed it was not in a hurry to catch up with it, but only a few dozen meters away, following its path in the scorching lava.

The red flame beast in front, with a crystal golden fur, is fine at all in this scorching magma, it may have never seen a human being, it is not very afraid, it can't go far, it has to look back at the thunderstorm behind it, and may also be thinking in his heart: "This power is very strange, why is it not afraid of this hot magma at all?"

The distance of more than ten miles below the magma is full of winding roadways, which are close to the center of the lava, and its temperature is not to say, if the thunderstorm cannot use the method of anti-five elements fire element, it may have already turned into a cloud of green smoke. At this time, he didn't even have the slightest damage to his robe, and he didn't even feel a little hot, just because he had merged with the fire element at this time, the fire element was him, and he was the fire element.

Finally came to a large lava cave, and there was no way out of it, the Red Flame Beast turned around, staring stupidly at the thunderstorm that came in with it, a pair of small eyes, constantly turning around, waiting for an opportunity to escape.

Lei Yu hadn't cultivated the secret of communicating with spirit beasts yet, so he could only stop a dozen meters in front of it, standing motionless, smiling, not wanting to disturb it.

"Master, set up a big array at the intersection and collect it in the blood thunder bead lava, it's pretty cute, I can also play with it. ”

"Okay," Lei Yu said, took out the five-in-one sheepskin array plate, quietly integrated into the passage mouth, and after activating the big array, Lei Yu walked towards it, saying as he walked, "Don't be afraid, it's quite haode inside, there are small stones to play with, and there are also lava, no worse than here."

As it approached, the Red Flame Beast sensed the threat, spewed out a scorching flame, turned and ran out, and fell into the large array arranged by the thunderstorm, which easily received it into the blood thunder bead.

Entering the Blood Thunder Bead, the small stone communicated with it, there was no problem at all, and with a smile, he came to the Thunder Burst Pool of the Blood Thunder Bead, where the temperature of the magma was even better than here, and the Red Flame Beast was pleasantly surprised to burrow into the lava.

After collecting the array, Lei Yu looked at the extremely lively fire crystals that were all over the ground and were brought back by the Red Flame Beast, and thought to himself, "Why don't you take advantage of such a rare environment to sacrifice the flames you emitted?"

Thinking of this, Lei Yu kept sacrificing and retracting his black flames, repeatedly doing the same monotonous action, merging with the tens of thousands of fire crystals in front of him.

Three days passed like this, and when Zuihou, the original black flame, now when it was sacrificed, the black had become very light, he stopped.

It is said that the color of the flame above the real sixth grade is completely colorless when it is sacrificed, and that is the real power, and at this time, the flame he sacrificed still has a faint black.

Lei Yu knew that the flame level he sacrificed at this time must be at the fifth grade or above, and it was impossible for him to rise again in this sacrifice, so he stood up calmly, beckoned to take back all the tens of thousands of fire crystals to the blood thunder beads, and let the little stone use these fire crystals to build a nest for the Red Flame Beast again.

"Master, you have gained a lot this time, and the flame grade is already the peak of the fifth grade. Little Stone said excitedly.

"Yes, when I go back, I want to put some effort into refining the elixir. ”

At this time, Lei Yu has collected the extremely lively fire element, gold element, and wood element, and there are still two elements left, so he can use these five elements to refine a powerful instrument according to what Lei Ming's predecessor said, and his heart is also full of expectations.

Don't look at the ubiquity of water, it is an indispensable thing for human survival, but it is really not difficult to find a water element with a lively nature like 'Tianyi True Qi'.

The lively water element required by the thundering predecessors must exist in the 10,000-year-old ice element, called jellyfish ice crystals, which only exists in the deep cold zone.

The earth element is the opposite, to find the least lively, the most calm, the thickest kind of the earth element, it is said that there is a 'Sky Blue Divine Sand' in the cultivation realm, there are only three hundred and sixty grains, but it can transform into trillions, and there is no way to do it. Lei Yu asked Xu Jiaci to pay attention to find out, if there is, no matter how expensive it is, he will get a few grains.

The excellent earth element, as the thundering predecessors said, only exists in places where people are inaccessible and animals are extinct, and there are still no thunderstorms.

The nest chosen by the Red Flame Beast, in this lava, is like a hearth, and the hottest air flow flows into the nest through the channel, in addition to countless fire crystals, Thunderstorm always feels that there should be something special, so when he retracts all these tens of thousands of fire crystals into the blood thunder bead, he is walking around, sensing the difference in temperature.

The hard work paid off, after many comparisons and searches, Lei Yu found a special place, that is, under the ground of its lair, in such a high temperature environment, Lei Yu did not dare to use a sword, but could only urge the true qi to suck out the things hidden under the ground.

A ring as big as a ring appeared in Lei Yu's hand. Xiao Shi exclaimed in surprise: "Superb Fire Crystal Ring!"

"Hehe, picked up a treasure!" said Lei Yu happily. According to the "Treasure Appreciation", "in the lava at extremely high temperatures, over time, a treasure will be produced, and that is this 'superb fire crystal ring'".

This pure yang thing is of great help to the cultivation of cultivators, in addition to being able to absorb the essence of heaven and earth more haode, it is also extremely beneficial to the cultivation of the mind and the cultivation of instruments.

After obtaining the 'Fire Crystal Ring', Thunderstorm had no memory of this place, and the Imperial Qi returned to the ground, leaving the lava peak, and heading towards the set goal.

When Lei Yu walked for most of the day and sat down to rest at a cliff, he took out the 'Fire Crystal Ring' to watch, only to see that as soon as the 'Fire Crystal Ring' came out, the temperature around him suddenly rose, and the thunderstorm confessed to this ring before dripping blood.

Throw the ring into the air, the 'fire crystal ring' flew into the air, the diameter suddenly became two meters in size, the flame on the ring rose, like a ring of fire burning in the air, the strong momentum, the scorching flame, made Lei Yu feel very happy, "If you meet the enemy, this ring will really make the opponent suffer a big loss." ”

At this time, at the foot of the mountain in front of you, there is an endless plain. In his divine sense, comparing the map, Lei Yu breathed a sigh of relief, walked through the grassland, and finally arrived at the "ancient battlefield" marked on the map.

Although the shallow hills and plains in front of it are endless, the green grass is green, and the purple is thousands of reds. Thunderstorm knows that in this seemingly calm, flower-filled grassland, it is not very peaceful inside, maybe there are a large number of spirit beasts waiting for him.

"Even if it's Longtan Tiger's Den, what are you afraid of, life is to survive in competition, grow and grow in competition, my thunderstorm is coming!"

That night, a thunderstorm rushed across the endless grassland. Along the way, there were also murderous spirit beasts such as third- and fourth-order black flame wolves, one-horned tigers, and red-spotted leopards, but whenever the thunderstorm sacrificed the 'fire crystal ring', those spirit beasts, unable to withstand the scorching flames, scattered and fled at once, without the slightest hindrance to the thunderstorm's footsteps.

When the morning came, the thunderstorm was already standing on the edge of the ancient battlefield.

Looking at the ancient battlefield, the square covering an area of thousands of acres is desolate, full of broken walls and broken pillars left after the collapse of huge buildings, dilapidated.

Walking in this barren grass, the ancient battlefield where all the sounds are silent, the heart of the thunderstorm, as if returning to the distant past, seems to sound in the ears of the tragic neighing, the sonorous sound of the golden iron horse, and the rumbling hooves of the galloping horses. The magnificent and splendid buildings, in the tragic and abnormal battle, collapsed one after another, leaving only this ruins and broken walls for future generations to hang.

The ruins of the huge buildings of the ancient battlefield, the ruins and broken walls that can be seen everywhere, the broken and broken stones, the columns, etc., all show the prosperity of the past and the scale of the entire magnificent city to future generations.

In the middle of this city, which was destroyed by the war, there stood a tall tower, between the broken and the complete, the desolate and the majestic, the contrast was so strong, but so harmonious, so perfect.

The intact tower, as if its mission is to exist for those who come after it, describes the strong contrast between before and after the war to the future generations, like a living picture scroll, showing the process of human growth.

Thunderstorm walked in the ruins and weeds of the ancient battlefield, approaching the tower.

Everything seems so mysterious, so sad, so depressing, but fortunately for thunderstorms, I have had the experience of a swamp and don't care about this.

With a sweep of his senses, no one existed within a radius of more than ten miles, and he slowly came to the square around the tower.

The square is indeed too wide, with a radius of dozens of miles, and against the backdrop of the hexagonal tower, Lei Yu feels like an ant, walking on a football field, so small.

Hexagonal tower, the tower is hundreds of meters high, after more than half an hour, walk through the square to the front steps of the tower. On dozens of steps, there is an arched main entrance.

Don't look at these dozens of steps, that's not ordinary, those who can go up, for thousands of years, among the countless practitioners who have come here, few people have climbed this step, of course, there is no chance, can enter the arched main gate, these things, of course, are only known after the thunderstorm.
