Yin Yang magic thunder, this is definitely a terrible lightning.


    Even to what extent?


    In the tens of millions of years since the ninth world, there are few people recorded in the history books who have subdued the yin-yang magic thunder. The only one is the Lei Zu in the thunder sea.


    The original Lei Zu was a real legend.


    Even Gu Zhun has to respect such a person.


    After all, rezu''s life is too legendary.


    Moreover, Lei Zu, who founded Lei Hai in those years, reached a terrible height at the peak of his life.


    It is said that the original Lei Zu accepted such a yin-yang magic thunder. From then on, there were records about yin-yang magic thunder in the nine realms.


    How terrible is yin-yang magic thunder?


    Some people have seen it with their own eyes. When Lei Zugang had just accepted and completed the yin-yang magic thunder, Tiandao dropped several Zixiao God thunder because of jealousy, and wanted to eradicate Lei Zu and his yin-yang God thunder, because Tiandao had perceived that the yin-yang magic thunder on Lei Zu was a great threat to himself.


    But even so, after Tiandao dropped Zixiao divine thunder, Lei Zu was still intact, and even the power of Yin-Yang magic thunder directly defeated Tiandao''s Zixiao divine thunder, but severely slapped Tiandao in the face.


    And since then, even the way of heaven did not dare to intervene in Lei Zu at his peak.


    It was not until many years later, because the energy of Yin-Yang magic thunder was too strong, and there were some mistakes in Lei Zu''s cultivation in his later years, that his control over yin-yang magic thunder was out of control, resulting in the internal lightning phagocytosis, which led to the fall of Lei Zu.


    But to sum up, Lei Zu''s life, even the way of heaven, can be hard. I''m afraid many emperors dare not do this.


    That''s why the horror of Lei Zu and yin-yang demon Lei is so deeply rooted in the hearts of the people.


    At this time, Zhang Zhen said yin-yang magic thunder, and Gu Zhun''s face also changed.


    No wonder.


    No wonder he felt something wrong in Leiyang Valley before.


    And when I grabbed the mine core, I also felt some other powerful and incomparable forces in the mine core.


    It turned out that there was a trace of Yin-Yang magic thunder here.


    It seems that this matter has become more interesting.


    This can also explain why those old people of Lei Hai are willing to let a core disciple like Zhang Zhen come out and hide in Shenxia sect for so many years in order to capture this thunder core.


    It is certainly illogical to say that it is only for a mine core.


    But if it''s for yin-yang magic thunder, it makes sense.


    "Yin Yang magic thunder! So it is!"


    Gu Zhun looked at the thunder core in his hand and said slowly.


    Even Gu Zhun has to re measure things like yin-yang magic thunder.


    After all, this is the ghost thing that ate Leizu back at the beginning.


    Lei Zu is such a figure, but Gu Zhun doesn''t dare to despise it at will.


    Gu Zhun certainly attaches importance to this treasure at the bottom of the box.


    But just at this time, Zhang Zhen on one side spoke. He rubbed his hands and said to Gu Zhun: "well, sir, we agreed before. I said everything you want to know. You see, should I..."


    Zhang Zhen also asked Gu Zhun with some expectations.


    After all, Lei nuclear is definitely good for Zhang Zhen.


    Not to mention the unique treasure of Yin-Yang magic thunder.


    So Zhang Zhen is naturally looking forward to it at this time.


    However, Zhang Zhen was also worried when he asked.


    What if the elder really repents at this time?


    This is not impossible.


    After all, this is yin-yang magic thunder.


    It''s not ordinary lightning. No matter who it is, they will be moved by such treasures.


    However, although Zhang Zhen thought so, what surprised him was that Gu Zhun was abnormal at this time, with the almost no intention of the going back, so he directly handed this thunder core to Zhang Zhen.


    There are two reasons.


    First, Gu Zhun is not the kind of person who doesn''t keep his word.


    Even if there is yin-yang magic thunder in this thunder core, it doesn''t mean anything. After all, although yin-yang magic thunder is powerful, it''s not the kind of thing that Gu Zhun really grabs with red eyes.


    Moreover, as an old guy who has lived for tens of millions of years, he can be said to be older than anyone, not to mention a small Zhang Zhen. Zhang Zhen is now the youngest of Lei Hai''s younger generation in Gu Zhun''s eyes.


    And at the beginning, both the old guy Leizu and the boy yuantianshen had a good relationship with Gu Zhun. Even one step away, Gu Zhun married them at Lei Hai. The relationship between the two has always been good.


    In this case, Gu Zhun, as an elder, can''t break his promise to Lei Hai''s people.


    This is not Gu Zhun''s style. After all, since he promised Zhang Zhen, Gu Zhun disdained to violate anything.


    The second reason is that, in fact, even if there are yin-yang magic thunder in the thunder core, it is not easy, or even impossible, to extract the yin-yang magic thunder from a thunder core with the realm and means of Zhang Zhen kid.


    Unless he can bring the thunder core back to his clan and hand it over to the old guys of Lei Hai, they may really be able to bring forward the yin-yang magic thunder based on their research on thunder core and thunder method.


    But the key is that it is impossible for Zhang Zhen to send the mine core back.


    After all, Gu Zhun is here watching him. Zhang Zhen can''t do anything under Gu Zhun''s eyes.


    If the boy can send the mine core back to the mine sea under such circumstances, Gu Zhun won''t have to mix up.


    So now Gu Zhun doesn''t have to worry about yin-yang magic thunder at all. What about lending it to you?


    At this time, Zhang Zhen also took over the thunder core with a surprised face. Originally, Zhang Zhen was still surprised. The elder didn''t mean to repent, but Zhang Zhen was also a smart man.


    The stakes can be figured out after a little thought.


    After Zhang Zhen figured out these things, he naturally understood what the elder meant, so his face was bitter at this time, but there was no way.


    So at this time, Zhang Zhen can only put away the thunder core first.


    Now, being in Leiyang Valley, it is naturally impossible to absorb this thunder core now.


    In case it is discovered by some monster or Shenxia sect, it will not be a good thing, so Zhang Zhen is ready to take it back for absorption.


    Gu Zhun naturally has no opinion on this.
