Looking at it, Xia Mu's whole mind was completely immersed in it, and a new world of laws was displayed in front of Xia Mu, although he only saw the tip of the iceberg of this world at present, but it was the tip of the iceberg that also brought an indescribable impact to Xia Mu, that is, a kind of ideological impact that was subverted by a new concept of fixed thinking in the past.

It...... It deeply shook Xia Mu's heart.

In the past, Xia Mu thought that the law was part of the Great Dao. Of course, Xia Mu's previous thoughts were not wrong, the law is indeed a part of the Great Dao, but apart from this, what is the law? What does it contain? For these questions, Xia Mu can't answer them before reading the secret book of "Law".

Therefore, when Xia Mu saw the definition of the law in the "Law", he had a feeling that it was okay to do so.

In an instant, Xia Mu seemed to see that the door of a new world called the law was slowly opening to him, and invisibly, his understanding of the law deepened a point, and he understood the existence of the law more thoroughly.

Airplanes!

Around Xia Mu's body, red lines of law slowly emerged, surrounding him, and it was the line of law that represented the law of flame.

Compared with the law line summoned by Xia Mu in the past, the flame law line that now surrounds Xia Mu's body seems to be a little more agile and ethereal, and it is no longer at Xia Mu's control like a dead thing.

At this time, Xia Mu's mind was still immersed in the "Law", and he didn't realize that when his mind was immersed in the "Law", he unconsciously condensed the line of the law.

And these condensed threads of law are still constantly winding and combining, trying again and again......

Every time these condensed lines of laws will change differently, good or bad, but no matter what, it is constantly changing and trying, as if it wants to confirm something with Xia Mu's consciousness.

I have to say that the secret book of "Law" can be included in the treasure house of the border battlefield by the high-level of the human race, and there is still a reason for setting the exchange conditions for 10,000 combat exploits, and the content of the law expounded in it can lead others to deepen their understanding of the law unconsciously, as for the extent to which it can be perceived, it depends on personal understanding and chance.

If you have a good understanding opportunity, you may be able to comprehend the origin of the Great Dao by relying on this "Law" alone, and if you have a poor understanding of the opportunity, even if you gain less, you can at least deepen your understanding of the law.

"Ding!"

At this moment, the Battle Medal on Xia Mu's body suddenly made a crisp prompt, and then an unfamiliar man's voice came out of it: "Yi Daoyou, come out, the things you exchanged have been delivered." ”

After repeating it three times, the voice disappeared, and Xia Mu instantly sobered up.

"It's a pity!" After coming to his senses, Xia Mu shook his head, but he didn't dare to slack off, hurriedly opened the door of the cave, and after lifting the ban, he flew out.

"You are Yi Daoyou?" As soon as Xia Mu flew out of the cave, a middle-aged man fell from the sky, holding a Qiankun bag in his hand.

"Yes, I don't know what the seniors call it?" Through the Battle Meritorious Service Medal, Xia Mu immediately confirmed that the middle-aged man in front of him was a Terran powerhouse who specially delivered goods to him.

"My surname is Li, just call me Senior Li. The middle-aged man said simply, and then said, "Just in case, I have to verify your identity." ”

Saying that, the middle-aged man surnamed Li didn't wait for Xia Mu to answer, and pinched the trick with one hand, and immediately the battle medal on Xia Mu's chest began to flicker, and soon showed a "Yi" word, there is also a blood line attached to this "Yi" word, and the end of the blood line is connected to Xia Mu's body, which seems to be a lifeline-like thing, if Xia Mu falls, then this blood line will also be broken invisibly.

"Identity confirmed, this is what you redeemed, you confirm it. The middle-aged man surnamed Li threw the Qiankun bag in his hand to Xia Mu.

Taking the Qiankun bag, Xia Mu's mind quickly swept away, and then raised his head and smiled: "The juniors confirm that they are correct, all the things are there, and the number is not wrong, thank you seniors for your hard work escorting you all the way." ”

"It doesn't matter. The middle-aged man waved his hand and said, "Since the things have been handed over to you, then my task is also completed, and I will leave." ”

After speaking, the middle-aged man's figure gradually dissipated, and it is not an exaggeration to say that it comes and goes like the wind.

Shaking his head, Xia Mu reopened the prohibition of the cave mansion, and then walked into the cave mansion.

Sitting cross-legged on the stone bed, he opened the Qiankun bag and directly took out the contents one by one, which were a jade jar printed with the water of the Thunder Tribulation, a bottle of Vajra Quenching Pill, a bottle of Ten Thousand Years of Earth Heart Milk, a bottle of Divine Healing Pill, and a jade bottle containing five drops of fire marrow.

Xia Mu put everything else into the Qiankun Ring, leaving the vat of Thunder Tribulation Water alone.

And the reason for this is also because this water of thunder tribulation must be used as soon as possible, because as time goes by, the power of the water of thunder tribulation will continue to weaken, and even in the end, it will become an ordinary liquid medicine, so generally speaking, as long as you exchange this water of thunder tribulation, you must use it immediately.

"Huh?"

After unlocking the seal of the jade jar, Xia Mu's eyes lit up.

I saw that the jade jar was filled with a pool of purple liquid, but this purple was very light, making the liquid look very clear and transparent, and if you carefully observed, it was not difficult to find that in this purple liquid, from time to time there would be nine different colors of thunder and lightning appearing, but soon they would disappear again, as if integrated into the liquid medicine.

"This is the Nine Heavens Divine Thunder, and there is more than one. Xia Mu was a little surprised.

In the legend, there are nine heavens, and the nine heavenly divine thunder refers to the divine thunder that was bred in these nine heavens, so it is named the nine heavenly divine thunder.

Xia Mu originally thought that this Thunder Tribulation Water only contained a kind of Nine Heavens Divine Thunder, but it didn't seem to contain nine kinds, no wonder the commentary would warn those with ordinary bodies not to use it.

You must know that a single Nine Heavens Divine Thunder, even after being refined by an immortal realm powerhouse, is not something that ordinary Five Elements Realm cultivators can withstand, let alone nine Nine Heavens Divine Thunder?

In Xia Mu's memory, the real Nine Heavens Divine Thunder is completely capable of threatening the powerhouses of the Undead Realm, and probably only those who are proficient in the Thunder Dao and are extremely powerful in the Undead Realm can subdue the Nine Heavens Divine Thunder.

Removing the jade slip that was attached to the outside of the jade jar, Xia Mu directly released a trace of divine thought and read it.

What is recorded in the jade slip is the method of using the water of thunder tribulation and some relevant information, but there are few key points, but the words of warning occupy a large space.

"With my physique, I shouldn't be electrocuted directly. Xia Mu cautiously approached the jade jar, wanting to feel how domineering this water of thunder tribulation was up close, but what disappointed him was that the jade jar, or the medicinal liquid's isolation effect on the Nine Heavens Divine Thunder, was too good, even if he relied on it again, Xia Mu couldn't feel the slightest feeling of electric shock.

Even if he put his palm on the water of the Thunder Tribulation, he still didn't feel it, it seemed that the Nine Heavens Divine Thunder was really perfectly sealed in the medicinal liquid, and he couldn't feel anything if he didn't soak it.

Xia Mu sighed, it seemed that the idea of wanting to feel the power of the Nine Heavens Divine Thunder before soaking was in vain.

"Well, I still have the Immortal Spirit Tree, and the worst case scenario is to use up another chance to resurrect. In the end, Xia Mu gritted his teeth, comforted himself, and jumped directly into the jade jar.

"Hey, it's so cold, this water of thunder tribulation is really magical. ”

Xia Mu gasped and found that the situation was completely different from what he thought, except for the cold at the beginning, there was no expected feeling of electric shock.

"Do you mean...... It can't be an expiration date, right?" Xia Mu's heart moved.

But soon Xia Mu felt that this idea was ridiculous, and after a short time, he felt a trace of abnormality, his skin felt as if he had been pricked by a needle, and the pain quickly penetrated through the skin into the flesh and bone marrow.

"Here we go. Xia Mu's heart sank, knowing that this water of thunder tribulation was beginning to exert its might.

In just an instant, his body really seemed to have been struck by lightning, and it was not an ordinary lightning strike, but a lightning strike that was dozens or hundreds of times more powerful than the lightning that appeared during an ordinary thunderstorm.

Burst!

Xia Mu directly spewed out a mouthful of old blood, and his whole body was scorched black in an instant, but before he could come back to his senses, wisps of lightning of different colors rose from the medicinal liquid in the entire jade jar.

And this is just the appearance of the Thunder Tribulation Water, what is really terrifying is the Nine Heavens Divine Thunder that is constantly infiltrating his body.

These Nine Heavens Divine Thunder were extremely domineering, directly impacting his limbs and hundreds of remains, and even the power of the divine soul in the Mud Pill Palace was implicated.

Burst!

Xia Mu coughed up a mouthful of blood again, and the sound of a fracture in his body seemed to come out, just a breath of time, and the Nine Heavens Divine Thunder that invaded his body caused him great harm before he could react.

Xia Mu's color changed at the first time, this water of thunder tribulation is really terrifying, for people with a slightly weaker physique, the violent impact just now is enough to kill them, such domineering does not seem to be weaker than the real thunder tribulation at all.

If it were someone else to bear it, it would probably not be as simple as Xia Mu coughing up blood, but it would explode directly on the spot and turn into a blood mist.

Of course, this is just the beginning, and no one knows what kind of situation will happen next, anyway, Xia Mu is ready to resurrect again.

At this moment, Xia Mu found that the Yin and Yang Life and Death Divine Spring he had absorbed at the beginning began to play a role, and the powerful self-healing ability allowed Xia Mu's physical body to be quickly repaired, and the ribs in his body that were broken by the Nine Heavens Divine Thunder were also connected, which made Xia Mu add a lot of confidence.

"Boom!"

At this moment, there was a thunderous sound in Xia Mu's body, as if a thunderbolt exploded directly in his body, immediately causing his mouth and nose to bleed, and his body almost cracked.
