The dense thunder and lightning came like a violent wave, constantly bombarding Zheng Zhi's body.
The power of this thunder and lightning is very terrifying, and each lightning arc is like a sharp blade, capable of cutting iron like mud.
However, at this moment, Zheng Zhi was protected by two strange fires. Although these thunder and lightning were powerful, they could not hurt Zheng Zhi at all.
Before those dense thunder and lightning could get close to Zheng Zhi, they were defeated by the strange fire emanating from Zheng Zhi's body.
Under the Lei River, there is a cave.
Zheng Zhi lowered his head and could not see the end of his sight.
The depth of this thunder river is probably beyond his imagination.
Zheng Zhi continued to dive deeper and deeper.
And as he gradually went deeper, the power of thunder around him became more and more powerful.
Zheng Zhi stretched out his hand to grab it, and saw a ball of thunder water with "sizzling" thunder light, which stung his palm.
He looked at the thunder water in his palm and said thoughtfully: "The power of thunder and lightning here is very strong, and it can be used to temper the physical body."
His physical body needs stimulation from external objects too much.
Just do it, Zheng Zhi did not hesitate at all, and directly removed the strange fire that protected his body.
Not only did the strange fire disappear, but all the body-protecting profound energy was put away by Zheng Zhi.
"Zizzi!"
The thunder water had no obstruction and hit Zheng Zhi's body unimpeded.
"Tear!"
In just an instant, Zheng Zhi's clothes were torn to pieces by the sharp lightning.
Only a naked body is left!
The terrifying light of lightning struck his body, causing Zheng Zhi to gasp in pain.
The lightning strikes the physical body, and the physical body resists it. The pain is not something ordinary people can endure.
Moreover, when you are in the thunder river, the force of thunder and lightning that strikes you is not just one or two.
It’s a thousand ways!
Zheng grinned in pain, and even his expression became distorted.
His physical body is certainly not weak.
But it can’t withstand the bombardment of so many thunders!
Soon, scars appeared on Zheng Zhi's fair and tender skin, which turned into a bloody mess.
But he still gritted his teeth and persisted!
Not only did he not give up, but Zheng Zhi continued to dive deeper into the Thunder River, where the power of thunder and lightning was even more terrifying.
Because Zheng Zhi's body has extremely strong recovery ability, this also caused his body to heal quickly even though he was constantly struck by thunder and calamity, and so on...
But it was during this period of continuous injury and healing that the flesh, flesh and bones were tempered and began to become stronger.
Zheng Zhi took out Tianyang Ginseng and Fire Dragon Stone.
It’s time for the Immortal Sun to take a further step.
Without a moment's hesitation, Zheng Zhi began to refine Tianyang Ginseng and Fire Dragon Stone while tempering his body with the power of thunder and lightning.
Eight Tianyang ginseng and eight fire dragon stones.
Eight materials in total!
Zheng Zhi's refining speed has long been different from what it used to be.
In just a few minutes, he had completely refined all the Yang Ginseng and Fire Dragon Stone that day.
He did not continue diving.
Instead, he stopped and began to concentrate on sprinting to the fourth acupuncture point.
The power of the medicine turned into a strong Nine Yang Qi and began to attack the four acupoints.
After practicing the "Immortal Body of the Great Sun" for so long, Zheng Zhi already knows all his acupoints and key acupuncture points well.
The process went smoothly without any deviation.
Coupled with the continuous brutal thunder and lightning that stimulated the physical body, Zheng Zhi made rapid progress.
"Break it for me!"
After a cup of tea, Zheng Zhi opened his eyes.
The whole body was shaken, and the Nine Yang Qi broke through the body like a strong wind and exploded.
The fourth acupuncture point is then opened.
The rich Nine Yang Qi in Zheng Zhi's body suddenly surged.
"The realm of the four acupuncture points is comfortable!"
Zheng Zhi breathed a long sigh of relief.
An indescribable feeling of comfort spread throughout every corner of the body.
The physical body has been strengthened again!
And Zheng Zhi's cultivation did not stop there.
He continued to dive and began to try to contact stronger lightning.
The powerful power of thunder and lightning stimulates its physical body, and every part of its flesh, meridians, and cells undergoes transformation under this stimulation.
And as we get closer to the bottom of the river, the thunder and lightning there become more terrifying.
Until the end, the thunder that Zheng Zhi came into contact with could not only destroy the body, but also the soul.
Of course, for Zheng Zhi, this is also an opportunity to temper his soul!
An hour later.
Zheng Zhi finally saw the bottom of the Thunder River.
The first thing you see is a huge crack at the bottom of the river.
And in that crack, the terrifying cold air overflowed.
With just a trace of contamination, Zheng Zhi's body surface was covered with a layer of frost.
This kind of cold air is not the pure severe cold air, but the cold air.
The coldness that does not belong to the human world!
Here, there is no longer any power of thunder and lightning.
There is only a shuddering chill.
Because of this cold air, those terrifying thunder powers cannot get close at all.
"What a strong yin energy!"
Zheng Zhi took a deep breath.
His eyes were full of surprise.
The Yinshiyouquan was born in this place with excellent Yin energy.
The environment in front of us is just suitable for the formation of Youquan.
"Sure enough, we came to the right place."
Zheng Zhi chuckled.
At this moment, Zheng Zhi no longer had the idea of continuing to temper his body.
After changing into a pair of neat clothes and wearing a bright and mysterious armor, I was ready to go to the crack to explore what was going on.
To be honest, he is no stranger to the underworld spring.
But I have only seen it in ancient books.
He had never seen it with his own eyes as to what it really looked like.
Therefore, at this moment, Zheng Zhi was still a little curious.
Just as Zheng Zhi was about to go, he suddenly sensed something approaching behind him and subconsciously turned around.
When I turned around, I was shocked.
An extremely huge head, as big as a meteorite, appeared behind him.
Those huge eyes like lanterns were staring straight at him.
However, although the eyes are huge and terrifying, they don't have much killing intent.
"Why are you here too?"
Zheng Zhi calmed down his fright and asked.
This huge figure is none other than the Thunder Tribulation Demon Crocodile.
"I'm a little curious and want to come and have a look."
The Way of the Thunder Tribulation Demon Crocodile.
"So you are curious too!"
As if he had discovered a new world, Zheng Zhi smiled and joked: "I thought you really had no interest."
"Let's take a look together?"
Zheng Zhi tentatively invited.
"never mind."
The Thunder Tribulation Demon Crocodile stared at the huge crack not far away and shook his head: "I feel a very dangerous aura. You'd better be careful."
"Then just wait here!"
Zheng Zhi rolled his eyes.
Why didn't he see that this big guy was so precious about his life...
Of course, he was complaining in his heart, but he didn't dare not take the warning from the Thunder Tribulation Crocodile to heart.
There was a sense of wariness in my heart.
Then, Zheng Zhi didn't waste any time, and stepped into the dark crack.
"Hoola!"
As soon as we entered, the biting cold wind hit us hard.
In addition to the melancholy sound of the wind, there was also the harsh whine of the innocent souls.
A biting chill rushed straight to the Tianling Cap.
Zheng Zhi was shocked to find that under the blowing of the cold wind, cracks appeared in the mysterious armor on his body...
