After saying goodbye to the black warriors in "Heiwu City", Su Yu gave the Qin family a golden seed. With the Qin family's potential and the "777" seed power that he originally had, obtaining this golden seed will definitely stimulate extremely powerful power. After that, he bid farewell to everyone again and left alone.

It has only been more than seven months since the end of the fifth century of December in the legendary period. Everyone felt the urgency, and Wang Heng and others could understand Su Yu's current urgency.

Leaving the "Heiwu City", Su Yu went deep into the "Million Mountains" and returned to the crater again. Looking around, there was no trace of people quietly around him.

Su Yu did not enter it immediately, but sat cross-legged and began to sense the skull he placed in the "Black Iron World".

This time, after Su Yu was about to enter the lost world again, he would devote himself to practicing. Until the end of the fifth century, he would no longer appear. Before entering, he would first contact Zhang Zhongmou and others from the "Black Iron World" to find out their news.

As the realm improves, Su Yu now can easily see the hall in the "Black Iron City" with the skull he relies on. When he saw Su Yu, Zhang Zhongmou, Jin Fuhua, Jiang Hai, Zhao Shichang and others again, Su Yu felt relieved as everyone was safe.

After a brief question, I learned that there is basically nothing big happening in the "Black Iron World" now. No one came to find trouble for the "Black Iron City". Only the wooden man no longer stayed in the "Black Iron City", but searched everywhere for a few sarcophagus sealing his other bodies in the "Black Iron World".

"I probably won't contact you again in the next seven months." Su Yu briefly said about what he was preparing to practice and could not be distracted.

"Su Yu, then when will you come back to see us?" Su Yu asked anxiously.

"Well, seven months later, seven months later, I will come back no matter what." Su Yu said affirmatively. Seven months later, on the end of the Fifth Age in the legend, it is said that all humans in the world will fall into this world. Su Yu will rush back no matter what, because those humans include his parents and his relatives.

After contacting Su Yu, Zhang Zhongmou and others for a while, they learned that everything is safe in the "Black Iron World" now, and that the Eski Demons did not have any special changes, and the top ten giant cities did not come to harass or deal with them. After letting go of all their worries, they took a long breath, then restrained all other thoughts, lowered their eyebrows slightly, jumped, unbuttoned the "exclusion seal" seal, and entered the "lost world" under the volcano.

Su Yu's current realm is the second level of the Golden Warrior, which is the level of "high-level demigod". The power of lightning is 600 million volts. In the next seven months, his main focus of cultivation is still to improve his thunder and lightning power. The energy contained in the chaotic core is extremely huge. In these five months of absorption, the chaotic core has almost not reduced the chaotic core. The remaining energy in the chaotic core is enough for him to increase the power of lightning to a terrifying realm beyond imagination.

According to Tezketlipoca's estimate, the power of 600 million volts of lightning can match the level of "top demigods". 700 million volts can compare to the peak demigods. If the power of thunder and lightning can threaten the realm of the gods, Su Yu still needs to go a long distance.

In the following month of practice, Su Yu still spent ten hours to transform the energy of the "Crystal Core" as before, increasing the power of the body's thunder and lightning. At the same time, he absorbed a new golden seed. Then half of the time he practiced the world power of absorbing water attributes in the sea water, and half of the time he sat cross-legged on the island, absorbing the world power of the earth, and inside his body, he was digesting the world power of the gold seed belonging to the world power of the gold.

The remaining five hours are spent resting and learning various techniques.

In addition, there is also an additional practical training, that is, Su Yu summoned the Qing Giant God and ordered the Qing Giant God to attack him.

Without using lightning, the current Blue Giant God is slightly higher than Su Yu's strength. Faced with this pressure and tempering, it can be said that Su Yu's strength has reached a terrible level of improvement.

As Su Yu's strength continues to improve, the summoned Green Giant God is becoming more and more powerful. It can be said that the Green Giant God is definitely the best opponent for practical training.

Although the Green Giant God is stronger than Su Yu, even if he does not use thunder power, Su Yu wins more than loses less. Every time he fails, he will summarize the reasons for his failure. In the next battle, his skills will be greatly improved.

Su Yu absorbed the first golden seed and digested it for three months before turning the power of the golden seed into his own use. However, Su Yu only took one month to completely absorb it into his own use. In the second month, Su Yu swallowed the third and fourth golden seeds. It only took Su Yu half a month to absorb it into his own use. At the same time, he also increased the power of absorbing the "wood" in the towering green trees.

At this moment, Su Yu finally broke through the second-level realm of the golden warrior and reached the third-level gold realm. His golden blood began to penetrate and merge into his internal organs, and ordinary blood was constantly forced to slowly seep out from Su Yu's brows and fingers.

However, as he entered the third level of gold realm, his cultivation speed suddenly slowed down. The gap between each level of the golden realm was extremely obvious. Similarly, it was difficult to break through the first level. Just looking at the black warriors who could not break through for thousands of years, you can know that although Su Yu had such generous conditions, after entering the third level of realm, his cultivation speed still slowed down with a large radiation. If you want to break through again, it seems that it is far away.

As Su Yu entered the third level of gold, the golden blood began to penetrate the internal organs, gradually, his golden blood and the power of lightning began to repel.

Now Su Yu's extraordinary power in his body is becoming more and more powerful, while the power of lightning is even more terrifying. It has now reached 700 million volts, and it is even faintly breaking towards 800 million volts. With the terrifying power of lightning, it has gradually lost balance with the extraordinary power in his body.

You should know that in terms of the mutation level of the body, Su Yu now has only a third-level golden realm, at most a super demigod, equivalent to Wang Heng's realm among the black warriors. The power of thunder and lightning, 700 million volts of thunder and lightning, can be completely matched by the level of a peak demigod. Now, Su Yu's thunder and lightning power is gradually reaching 800 million volts. It can be said that its power has gradually begun to surpass the realm of a peak demigod, and has lost balance with the extraordinary power in his body.

Faced with this situation, Tezketlipoca seemed to have considerable experience. According to his instructions, Su Yu began to try to guide the lightning power in his body, gather it on his back, and then form the form he wanted.

Tezketlipoka's experience is very simple, that is, since the increasingly powerful lightning power suppresses the progress of the extraordinary power in the body, it will guide the power of lightning out of the body and create the extension of the body outside the body. Now Su Yu's thunder and lightning power can be easily completed and completely solidified. After considering it, Su Yu used this terrifying lightning power to form a new pair of lightning-like golden wings behind him.

With the pair of silver wings that he originally had, Su Yu now has another pair of golden wings solidified by lightning.

At the beginning, these were just two very rigid and simple golden wings. As the power of lightning became stronger and stronger, gradually, the pair of golden wings became larger and larger, and the patterns on them, and even the golden feathers, gradually appeared.

Compared with this pair of golden thunder wings that are becoming more and more beautiful, the original pair of silver wings looks extremely ugly, small and simple.

After solving the problem of losing balance by suppressing the power of lightning and the power in the body, the power in Su Yu's body evolved and quickly became popular again.

When the fifth month was the tenth month of his cultivation in this lost world, Su Yu finally felt the signs of an upcoming breakthrough again.

Now Su Yu can absorb five world powers of the ocean, island, green trees and fire clouds in the sky at the same time and gold seeds. Now, a gold seed can only support Su Yu for a few days, and later, even a gold seed needs a day.

Tezketlipoca looked at the fewer and fewer golden seeds on the green tree and murmured: "Finally, the power of the world in this lost world has become less and less effective on Su Yu. Soon, it will no longer help him here."

Tezketlipoka, who had only practiced here for a year, had reached a realm that had made the power of the world invalid for him. Now Su Yu has gradually reached such a realm, and the power of the world here has become smaller and smaller in effect on Tara.

The golden seeds were almost exhausted by Su Yu. If you want to produce such a tree of golden seeds, you are afraid that it will take thousands of years again.

Ada only took one and did not use the second one, just because the second golden seed was invalid for her.

Ada was constantly calculating the day, and it was getting closer and closer to December 21, the end of the fifth century in the legend.
