"There's really nothing you can do, then arrange a simplified version of the Four Elephants Heavenly Array," Zhang Yu couldn't help it, and Mochen could only reluctantly agree.

"The Four Elephants Tongtian Array, after the successful layout of the original version, can conjure up the Four Elephant Divine Beasts - Green Dragon, White Tiger, Vermilion Bird, Xuanwu, infinite power, it is said that the complete version of the Four Elephants Tongtian Array can even be suppressed by the Martial Saint! ”

"Now, according to my instructions, you first arrange the four things of Jiaolong Scales, Phaseless Stone, Sky Spark, and Red Flame Mink Demon Crystal around this valley, and then place the spirit stones according to the instructions on this drawing to make a formation base. I'll start carving the pattern later, remember, wait a minute. In each formation, you have to infuse me with soul power, only in this way can they be activated and exert the power that the great array should have. ”

"However, our formation is too rudimentary, and at most it can withstand a few attacks from the Heavenly Tribulation, and after that, the formation should be completely shattered. In this way, it is really worth the loss, and it is better to use the materials of the array to buy some elixir for him to recover. Mo Chen explained to Zhang Yu.

"That's better than nothing, we can't predict the power of the Tribulation, we can only do our best to reduce the damage of the Tribulation to Xiao Hei, as long as we can let him survive the Tribulation safely, even if it costs more, I am willing. Zhang Yu said without thinking.

In contrast, money is something outside the body, and naturally Xiao Hei's life is more important, as long as he can protect Xiao Hei well, Zhang Yu will never spare these expenses.

"Lin Yan, you are optimistic about Xiao Hei here, I will go to the valley over there to set up the formation now, and I will come back to you later. In order not to leak the existence of ink dust, Zhang Yu could only arrange Lin Yan here temporarily.

"Brother Yu, don't worry, with me, Xiao Hei will definitely not be hurt in the slightest. Lin Yan said with a package ticket.

"I'm leaving. ”

After Zhang Yu said hello again, he left the hillside and headed towards the ravine.

In order to maximize the effect of the formation, Zhang Yu limited the Four Elephant Heavenly Array, which had been reduced countless times, to within ten zhang.

Not to mention the value of the four main materials of the array, just the medium-grade spirit stones, Zhang Yu spent as much as five or six million, laying a thick layer in the ground to supply the operation of the large array.

In the arrangement of the formation, Zhang Yu played more of an auxiliary role, Rao was so, after filling all the soul power in the formation, he was as tired as a dog.

"Master, is that okay?" Zhang Yu asked weakly.

"Well, after Xiao Hei enters the center of the big array, he can open the formation by standing on the formation eye. Mo Chen said a little weakly.

The portrayal of the formation is a laborious thing, and the soul power consumed is also extremely terrifying, and there can be no mistake in the depiction, otherwise, if you are not careful, it may lead to a loss of the whole game.

"Then you can take a break, thank you. Zhang Yu thanked him from the bottom of his heart.

"With Xiao Hei's strength, since you dare to come to cross the Heavenly Tribulation, you must have a certain degree of certainty, and you don't have to worry too much. After a while, I will continue to sleep to restore the soul power I have consumed, and for a while, I will no longer be distracted by the outside world. After Mo Chen finished speaking, he once again submerged into Zhang Yu's sea of knowledge and fell into a deep sleep.

And Zhang Yu returned to another hillside and began to wake up Xiao Hei and prepare for the catastrophe!

"Big brother, take it easy, I don't know, I thought it was you who crossed the catastrophe. If you put a hundred hearts in it, I still have confidence in surviving a thunderstorm. Xiao Hei smiled slightly.

"By the way, if you refine this defensive armor, it can also resist some damage. Zhang Yu took out a treasure-level defensive armor from the storage ring and handed it to Xiao Heidao.

Mysterious weapon-level weapons are already rare, and mystery-level defensive armor is even rarer, so far, Zhang Yu has never seen anyone have it. This low-level treasure-level armor was obtained by Zhang Yu last time he killed Feng Wenbin, because he was also refining his body, he had always been sealed in his storage ring, and it finally came in handy today.

"Thank you, big brother. Xiao Hei knew that these were all Zhang Yu's intentions, so he didn't shirk it, and after accepting it, he began to refine, and soon put it on his scale armor.

"Be careful!" After admonishing him again, in order not to let the Heavenly Tribulation be mapped to him, Zhang Yu and Lin Yan also retreated rapidly towards the distant hillside, and Xiao Hei stepped into the simplified version of the Four Elephants Heavenly Array, and after the entire formation was fully opened, the terrifying power of the monarch-level demon beast also burst out with all its might.

After no longer hiding his breath, the clear sky was suddenly filled with many dark clouds, covering the sky and the sun, the sky suddenly darkened, and an extremely depressed feeling quickly spread, above Xiao Hei's head, a huge black vortex was condensed, and it could be seen in the roar that the endless power of thunder and lightning was slowly condensing.

Zhang Yu and Lin Yan in the distance were watching with some apprehension, and they also knew that the catastrophe could only rely on Xiao Hei himself, and they couldn't help at all.

"Come on, let me see how powerful you really are!" Xiao Hei raised his head and looked at the rapidly condensing thunder, and said with some expectation.

"Boom!"

A deafening thunderclap sounded, and silver lightning drilled out of the black whirlpool, like a silver dragon, dancing wildly, condensing into a sea of thunder above Xiao Hei's head.

The coercion emanating from the sea of thunder made people feel a tingling feeling even if they looked at it, Zhang Yu felt that if this terrifying and outrageous thunder power was poured into Black Tiger City in an instant, Black Tiger City would definitely turn into nothingness in an instant, and even a peak powerhouse like Jian Wangui would definitely not be able to escape.

However, during the tribulation, the thunder will land one by one, which will give the robber a buffer period, otherwise, any demon beast that dares to cross the tribulation will have been annihilated by this terrifying thunder tribulation.

"The power of the Heavenly Dao is really terrifying!" Lin Yan couldn't help but be shocked.

"God, you must let Xiao Hei be safe. Zhang Yu prayed silently in his heart.

"Boom!"

There was a sound as if the heavens and the earth were collapsing, and the silver sea of thunder suddenly expanded more than doubled, and the pervasive coercion pressed the ground down to a thick layer.

"Click!"

Suddenly, a thunderbolt fell from the sky without warning, slashing at Xiao Hei's head, and in an instant, sand and rocks flew around the valley, the wind blew fiercely, and countless vegetation were destroyed in one fell swoop. The terrifying energy burst out, and the four elephants through the sky array were all trembling violently, and you could clearly see the energy ripples on it spreading out intently.

Although the Four Elephants Heavenly Array trembled violently, as if it was about to shatter in the next moment, it finally succeeded in resisting this first thunderstorm. With the protection of this formation, Xiao Hei survived the first thunderstorm unharmed.

"It's not bad, this formation didn't make my efforts in vain. Zhang Yu said happily.

"Under normal circumstances, the tribulation will be based on the talent of the tribulator, and the next six to nine tribulation thunders will not stop, looking at Xiao Hei's performance, at least he has to endure seven thunder tribulations to succeed in the tribulation, and this tribulation thunder is stronger than the other, and the following is the main event. Lin Yan said with a solemn expression.

After successfully surviving the first tribulation, Xiao Hei also had a moment of rest, raised his head, and always paid attention to the changes in the tribulation.

"Click!"

There was another loud bang, and the second thunderbolt also fell from the sky, slashing fiercely at Xiao Hei, only three minutes in between.

"How could it be so fast, in my inheritance memory, the interval between the two tribulation thunderbolts is basically five minutes. While Xiao Hei was shocked, he was also ready to break the formation at any time and resist with his body.

This time, the Four Elephants Heavenly Array shook even more violently, the silver light flickered, and after a while, cracks spread over it, and the surrounding formation bases all made a loud explosion, but it finally held on.

"The third thunderstorm, this big array is absolutely finished, but it can be regarded as overfulfilled the task. Zhang Yu, who was nervous, took a breath and said.

After about three minutes or so, the third thunderstorm also arrived as scheduled, and the power of this thunderstorm was almost thirty percent stronger than the first, and the power was even more terrifying.

At the moment when he first came into contact with the Four Elephants Heavenly Array, the formation could no longer resist it, and the four formation bases completely shattered almost at the same time, and between breaths, they disappeared.

Seeing the collapse of the formation, Xiao Hei did not have the slightest fear, and with a roar, he greeted him, and the power of qi and blood in his body rushed out, fighting against the author of the thunder with his body.

"Bang!"

With a soft sound, the treasure armor that Xiao Hei had refined was also turned into countless fragments and scattered all over the ground under the bombardment of the thunderstorm, but the third thunderstorm was finally exhausted, and it did not cause any substantial damage to Xiao Hei.

"The third way, Xiao Hei is still in peak condition, if nothing happens, he should be able to get through it safely, but he will inevitably turn around and be seriously injured in the end. Zhang Yu silently analyzed in his heart.

After experiencing three more tribulation thunders, Xiao Hei's face really became solemn, because he found that the power of the fourth tribulation thunder that had been conceived had soared to twice that of the first tribulation thunder all at once!

"It's unreasonable, it's unreasonable!" Xiao Hei muttered to himself with some confusion.

As far as he knew, this fourth thunderstorm should be sixty percent stronger than the first one, and so on, and so on, and continue to increase, so that the irregular increase was once again greatly beyond his expectations.
