The purpose of Tang Yu coming here is to collect fire-attribute energy stones. You can’t stop collecting fire-attribute energy stones because of some things!

The most important thing is that there is no longer any material on him that can arrange the spirit gathering array. Now he can only count on these arrays to help him collect enough materials.

Even if you don’t wait until you return to the heavenly realm and then refine Xuanyue Killing’s magic weapon, in the world where the Fire Mi Castle is located, Tang Yu has to use fire-attribute materials to arrange a large array.

Even though he already has the experience of Xiaohuo, to be honest, Xiaohuo's experience cannot be used in the magic weapon that Tang Yu refines for Xuan Yue.

Because Xiaohuo has his own consciousness and knows how to fight against the thunder tribulation. If it is a magic weapon refined for Xuan Yue Killing, even if the weapon spirit appears inside, it will be a ignorant weapon spirit. It is absolutely impossible to make it resist by itself.

Therefore, Tang Yu could only try his best to help this magical artifact that was about to be refined to fight against the thunder tribulation.

Of course, Xiaohuo's experience is also helpful, at least let Tang Yu know that the artifact he refined and the thunder tribulation he wanted to fight against may be very terrifying.

This also made Tang Yu rather go more routes and collect more fire-attribute energy stones now, so as not to waste so many good materials in vain, so that the successfully refined artifacts will be directly blown up under the thunder tribulation.

After spending a whole day, Tang Yu and Xiaohuo plundered all the spirit gathering arrays that had been arranged before.

Perhaps because time has passed for a long time, the number of fire attribute elements around these spirit-gathering arrays has increased again.

Tang Yu collected fire-attribute energy stones from various formations, which reached 50 million.

Although it is still much worse than the efficiency of the energy condensation stones of the previous formation, it is still much worse to have 50 million fire-attribute energy stones, which gives Tang Yu a little confidence.

More importantly, Tang Yu was surprised to find that some thunder attribute elements appeared in the fire attribute energy stones collected this time.

Tang Yu knew that these thunder attribute elements must have come from the thunder tribulation of Xiaohuo.

But the problem is that the location of the Xiaohuo Tribulation is still a distance away from these large arrays, but at such a long distance, it is an extremely surprising thing to allow the spirit gathering array to collect the thunder attribute elements inside.

Of course, this also means that the elements here flow very quickly in the world where the Fire Miscellaneous Castle is located. It may not take long before these large arrays arranged by Tang Yu can collect a lot of energy crystals again.

However, it must have to wait until Tang Yu returns from the Huomi Castle.

"The 50 million fire-attribute energy crystal is pretty good. But it's still a little bit short of the target!" Tang Yu said in surprise and helplessly.

"Master, why don't we wait for a while?" Xiaohuo couldn't help but say when he heard Tang Yu's words.

"If you don't wait, these big arrays will not be destroyed by others. You haven't seen that the collection efficiency of these big arrays is slower now? If you want to collect 50 million fire-attribute energy crystals, it may take more than a week. In one week, it will be enough for us to come back from the Fire Mi Castle." Tang Yu said confidently.

Tang Yu's confidence comes entirely from Xiaohuo.

The strength of the little fire blood-colored silk thread made him feel confident that they would definitely gain something when they went to the Huomi Castle this time.

"It depends entirely on the master." Xiaohuo certainly would not object to Tang Yu's orders. After hearing Tang Yu's words, he said with a smile.

"Then let's go!" Tang Yu took the lead and flew towards the Huomi Castle.

Although the world where the Firemied Castle is located is like a desolate moon, and at first glance, there is a desolate area everywhere, as if it is difficult to distinguish the direction, for Tang Yu, there is still no problem in distinguishing the direction like this.

If he even forgot the direction of the Huomi Castle, he would be laughed at by someone.

Before we knew it, time passed quickly, and Tang Yu and Xiaohuo had already flew through countless areas. Finally, traces of the Fire Miscellaneous Castle appeared in our eyes.

The Huomi Castle is the only building that Tang Yu and his group have seen so far in this desolate world.

Just like the feeling of walking through the deserted desert and suddenly seeing people, it is full of surprises.

"Master, don't go there first!" Xiaohuo said immediately.

"What's wrong?" Tang Yu, who was about to speed up and flew to the Huomi Castle, was stunned when he heard Xiaohuo's words and asked in confusion.

"You forgot the elemental snakes at the door!" Xiaohuo reminded.

"We can easily solve those elemental snakes before you have overcome the tribulation. Now that you have overcome the tribulation, your strength has improved so much, can you still be afraid of them?" Tang Yu said in a swelling manner.

"No, master, I mean, we can try this and see if it is useful." Xiaohuo suddenly took out a token, which was the Fire Secret Token snatched from the Fire Demon Snake.

"This is the fire secret token taken from the fire demon snake, right?" Tang Yu asked in surprise after seeing the token.

"Yes, this is the Fire Secret Token. Since this thing can allow those practitioners of the seventh realm of the True God to come out of the Fire Secret Castle, it means that this thing is very important to the entire Fire Secret Castle. Maybe those elemental snakes will think that we are our own people with this token." Xiaohuo said with a wicked smile on his face.

"But if this happens, will it lead to you being trapped in the Fire Mi Castle and unable to come out!" Tang Yu realized this problem and said nervously.

"It shouldn't be possible?" Xiaohuo was stunned when he heard Tang Yu's words, his expression became nervous, and he said awkwardly.

"Or, you should enter the Shangji space first and strive to avoid contact with the large array outside the Huomi Castle. I guess those people in the Huomi Castle should only be affected by the large array and cannot leave." Tang Yu pondered for a moment and said.

"Okay!" Xiaohuo nodded and agreed to enter the Shangji space. However, before entering the Shangji space, he still reminded him: "Master, after entering the Huomi Castle, you must release me, otherwise I am worried that you will be in danger."

"I think I pay more attention to my own safety." Tang Yu said with a lot of laughter.

After sending the little fire into the energy space, Tang Yu took the token and flew towards the Huomi Castle carelessly.

Although Tang Yu's face looked very indifferent, in fact, he was completely alert in secret. He always paid attention to the fluctuations of the fire-attribute elements in the void. As long as they had abnormal movements, they would immediately launch an attack and smash them directly.

However, until the energy protective cover outside the Fire Mi Castle, Tang Yu did not feel any energy fluctuations in the void.

I don’t know if the token really has a great effect, or because the Fire Life Ghost already knew about Tang Yu’s arrival, he specifically notified these Fire Elemental Snakes to prevent them from appearing, thus making Tang Yu relax his vigilance.

Of course, Tang Yu would not relax his vigilance. The moment he passed through the protective cover, he put the Fire Secret Token into the ring, and then walked into the Fire Secret Castle.

"That guy didn't come out?" Tang Yu glanced at the three-story building where the Ghost of Fire Life was located, muttered in surprise, and immediately released the small fire from the Shangji space.

"Master, have you encountered the attacks of those fire elemental snakes?" Xiaohuo asked impatiently as soon as he appeared.
