However, Ziyan fell in love with No. 402's spirit sword, and immediately took it back honestly and unceremoniously, making 402 want to cry without tears. As a senior earth immortal, he was bullied to this extent by two young people from the Ning Dan Realm, and there was no one left. But he just felt distressed for a while and then thought about it, even he himself became a slave, what is the pity of a sword?

It is said that Tian Xu summoned the Shennong hoe, which had already recovered his physical strength, again, this time he further increased the size of the Shennong hoe, and began to dig at a speed of two to three shovels per second, each shovel of three or four tons, and the soil that he continuously threw was almost connected in the air, forming a thick earth dragon, transporting the soil and stones at the bottom of the lake to the shore, and the newly expanded land extended into the distance at a speed visible to the naked eye.

At the end of the day, the area he excavated was only twice as large as the last time he excavated the scallop pond, but the depth was much deeper, with an average depth of 60 meters. Now this huge pit has not been filled with water, and it looks like it is on a grand scale.

The audience of the Three Immortals saw Tian Xu's process of condensing Dan by the lake two days ago, and they were all amazed by the earth-shattering momentum of his condensing Dan. Today, seeing Tian Xu's crazy digging process, they were even more shocked, they didn't feel the fluctuation of aura from Tian Xu, who was working frantically, obviously he completely relied on his physical body to complete this work. It is estimated that only such a powerful ability can allow Tian Xu to be able to compete with the earth immortals and win the battle only with the high-level realm of Ning Dan.

After digging non-stop for a day, Tian Xu stopped. His stamina was close to the limit and he needed a break. The Shennong hoe in his hand is worse than him, after all, he has only recovered a small part of his strength, and it is already his limit to work with Tian Xu for such a day of high-intensity work. One person and one hoe were successively thrown into the freshwater lake, Shennong's hoe sank quietly to the bottom of the lake, motionless, but Tian Xu swam quickly in the lake for a while, and his physical strength recovered three or four percent before stopping. When he completed the ninth Ning Dan, he had vaguely thought of the shadow of an important issue, and at that time, because he wanted to cultivate the Sun Chasing Technique, this matter was temporarily put aside by him. Now that he had time, he had to figure it out.

He carefully recalled the scene at that time, at that time he had just completed the Ning Dan, and felt that this ninth order was still not the limit of his Ning Dan, at least he had to perform the tenth Ning Dan again. This thought came to him when he felt that others were going to start looking for the opportunity to cross the tribulation and ascend after nine condensations.

"What the hell is the problem?" Tian Xu muttered to himself, but he couldn't remember anything. He thought back to his recent cultivation process, "Is it related to bioelectric fields or electromagnetic waves, and if so, what is it?" He felt like he was on the edge of the problem, but he still couldn't remember. It's no wonder that he just let this thought slip through his mind at that time, and didn't think much about it at all, and now that a few days have passed, where can he still find the clue?

However, he firmly believes that the problem should be related to the electric field and electromagnetic waves that he has been studying a few days ago. Also, since it was thought of when I thought of the ninth order of Ning Dan, it is likely that it is also related to Ning Dan or the Tribulation.

"What does bioelectric field and electromagnetic waves have to do with Ning Dan or the Tribulation?" Tian Xu changed his mind, and things suddenly became clear, "That's right!

When the Thunderstorm comes, the violent Thunderstorm will produce extremely high voltages, accompanied by a huge amount of electricity and extremely high temperature plasma, producing extremely powerful destructive effects. Tian Xu had seen people cross the robbery three times before, and he still remembered the power of the terrifying thunder, but he never understood the specific means of the raiders to resist the thunderstorm. At that time, his idea was very simple, if he figured out how to resist the tribulation thunder, wouldn't he be able to achieve the tribulation? This was not something that he could touch at all as a low-level cultivator who had just condensed the pill, so he didn't even have a brain to go over there.

Now that I think about it, the effect of the thunderstorm on cultivators is mainly concentrated in two aspects: high-voltage electricity and high-temperature plasma attack.

The effects of high-temperature plasma are similar to common high-temperature flame attacks, except that the temperature is higher and can be resisted by conventional methods.

The most terrifying thing is the high voltage of more than one million volts. Compared to the bioelectricity in the human body, which was less than one volt, this voltage was too high, high enough to easily destroy a cultivator's bioelectric system. And bioelectricity is the conduction mode of nerves, and the powerful high-voltage electricity can directly destroy the consciousness of the cultivator, without consciousness, there will be no life, and the powerful power of thunder should mainly lie in this.

In previous research, Tian Xu has confirmed that the bioelectric field is caused by neural activity, and most importantly, his mental field, mental communication, and mental attack that he has just been able to do a little are all realized by the bioelectric field brought about by strong neural activity.

Then the question arises: How can he face the attack of the thunderstorm with these spiritual abilities of his own? If he is completely destroyed during the tribulation, even if he can barely succeed in the tribulation, his strength will be greatly reduced. And how can soul cultivators like Aunt Xu and her own mother, or cultivators who mainly rely on spiritual abilities, survive the tribulation? Could it be that the bioelectric field created by their spiritual power can already compete with the powerful tribulation thunder? This is obviously not right, and there should be other solutions to the problem.

Then he thought of another question, that is, the spiritual imprint left by the cultivator on his aura, and he also suspected that it was the effect of the bioelectric field. If this is the case, then this spiritual imprint should not be able to continue to exist after the powerful tribulation. However, judging from the scene of the Great Elder's tribulation that he saw at the beginning, even if the spiritual imprint on the aura was weak, it would still be able to avoid the high-voltage electric attack of the tribulation thunder, otherwise a person like the Great Elder would not be able to successfully cross the tribulation no matter what.

He suddenly remembered that the golden blood of 402 that he had collected a few days ago, as well as the piece of aura body that he had forcibly torn off, were still in his spiritual realm. At that time, because the aura in the Medicine King Bucket was enough, he forgot about it after putting it away. He hurriedly took these things out, and found that the aura that made up these blood and bodies really still had the will of No. 402 remaining, and if he didn't use the Heart Purification Spell to forcibly erase it, these spiritual imprints should have existed for a long time.

After careful study, Tian Xu found that every aura molecule in this part of the aura body of No. 402 has the spiritual imprint left by No. 402, and these spiritual imprints of the aura seem to have their own thoughts, although this kind of thinking is quite simple, but when a certain number of such molecules are combined, they can produce a strong enough will. This is simply a replica of the collective will of the plateau jade bee or Shizhi!

In addition, the spiritual imprint on this aura was indeed the same as he imagined, a faint electric field. As for how the electric field inside a single Reiki molecule is generated, it is not something he can analyze.

Tian Xu has always thought that his understanding of aura is quite clear, and he started with his understanding of aura at the beginning, but now he has doubts about himself.

His Dan Spirit is like a doppelganger of his pure aura, and the Dan Spirit has its own separate mind and shares consciousness with his Buddha-figure. Other than that, the form of existence of the Dan Spirit was almost no different from that of an ordinary Saint Realm Immortal. However, at this time, Tian Xu was also puzzled about this point, is the Dan Ling, who has not experienced the thunder tribulation, really the same as the Earth Immortal? He put away the flesh and blood of 402, summoned the Dan Ling, and took a small part of the spiritual energy from the Dan Ling to study it, and he found that the spiritual energy taken from the Dan Ling was basically the same as the spiritual qi and body on the body of No. 402, and they all had spiritual imprints, and these spiritual imprints were perfectly compatible with his own consciousness, so he had never noticed the existence of these spiritual imprints. It's just that Dan Ling doesn't have that kind of golden blood on his body, but he doesn't know why.

In addition, he was quite puzzled, that is, the golden blood of 402 did not seem to be different from the flesh, and he didn't know why it could manifest itself in two completely different states. Judging from the performance of the 402, the Great Elder and the Twin Body Immortal Toad who had been injured by him, they all seemed to cherish this golden blood very much, and the importance of it was far greater than the importance of the body.

Tian Xu's last doubt didn't last long, and Dan Ling helped him give the answer: "What's so strange about this." Didn't you notice that my gold pill and yours were golden, exactly like those golden blood. Because your golden pill is completely made of this golden blood, without that other color component, of course, there is no other golden blood. ”

Tian Xu knew that because Dan Ling was composed of aura, he was more sensitive than his deity in this regard, so he handed the question to Dan Ling: "Then what's the difference between these two kinds of aura?"

Dan Ling said without thinking, "I don't know. I don't have that kind of thing. ”

Tian Xu asked Dan Ling to go to the spiritual realm to study the piece of "meat" torn off 402's shoulder, and he went back to consider the issue of bioelectric field again, and as for the matter of electromagnetic waves, he put it aside for the time being. He had a hunch that as long as he understood the problem of bioelectric fields and aura imprints, the matter of electromagnetic waves might be solved and no longer be a problem.

This time, Tian Xu studied how to use conventional methods to resist the high voltage of thunder.
