A pound of Yin Yan stone powder was enough for Tang Yu to break the runes on this huge coffin, so he began to get busy.

Ten minutes later, a pound of Yinyan stone powder was almost consumed by Tang Yu, and the evil demon crystals also changed. Because it was not enough, Tang Yu even made a few more evil demon crystals and carved patterns on it, which exhausted all the Yinyan stone powder.

As for the remaining Yin Yanshi, Tang Yu was naturally plundered into the ring, and he might be able to use it in the future.

"Xiao Qi, you can retreat a little, or go back to the energy space first!" Tang Yu stood up and said with a serious look on his face.

"Master, Xiao Qi should go back to the energy space!" Xiao Qi thought for a while and said.

"Then I'll send you back!"

With a "swoosh", Xiaoqi disappeared.

The reason why Xiaoqi chose to return to the energy space was not because she felt that if an accident occurred, she could immediately come out of the energy space to help Tang Yu, but if she stayed outside and appeared in that vortex-like place, she would probably have no way to find Tang Yu again.

"go!"

Tang Yu used the energy of true qi to control nearly ten evil demon crystals and slowly approached the huge coffin.

Tang Yu also noticed that the runes on the observation were all portrayed at a height of less than three meters, which was exactly in line with what Xiao Qi said, if the height exceeds three meters, it would be shot back to the ground by an inexplicable energy.

So Tang Yu guessed that this was probably set at the beginning, otherwise why was the height just three meters!

Tang Yu did not try. If he used the evil demon crystal to use the energy of the true energy, he could send it to a height of more than three meters. What he wanted to do now is to destroy the runes on the coffin, or erase them directly. As for the others, they were not what he wanted to care about now.

In fact, since Tang Yu was able to understand this rune, it would be too easy to break it.

The evil magic crystals that he had touched were now in his hands, just like a blackboard eraser, and the runes engraved on the coffin were written in chalk on the blackboard. After a slight eraser, they disappeared.

The situation is so simple, but some of the things contained in it are definitely not that simple.

One of the evil demon crystals wiped off some runes engraved on the coffin, and with a "bang", it suddenly exploded and shot out a ball of gold powder.

Tang Yu smiled and immediately used the energy of true energy to collect the ball of gold powder that exploded in the air, which looked like it was about less than a few dozen grams.

After putting it in the ring, Tang Yu continued to take out a new passive evil crystal and began to wipe the runes on the coffin.

"Bang!"

Another explosion, and the evil demon crystal exploded out a ball of gold powder again, and Tang Yu continued to collect it happily.

In this way, after all the evil demon crystals in Tang Yu's hands that had moved and exploded, Tang Yu also erased all the runes printed on the coffin.

As for the golden powder, Tang Yu also collected nearly 200 grams, but in fact there was not much, just a small handful.

"Jin Ye stone powder, I didn't expect it to be able to collect it back. Hehe, I'm very lucky! I'll use it in the future!" Tang Yu said excitedly.

The purpose of Tang Yu using the evil demon crystal is actually to collect Jinye stone powder. Otherwise, there would be no need for such trouble. Just use Yinyou Stone to crack this rune.

It's like a person who has never learned that one plus one is equal to a few, and he has no idea the answer at all, but after knowing it, he will definitely know that two minus one is equal to one.

Although the runes that Tang Yu comprehended are not that simple, they are almost the same, especially for Tang Yu, who has learned a lot of rune knowledge, it is actually even simpler.

He carefully put the collected Jin Ye stone powder into a jade box and then put it into the ring. Tang Yu raised his head and looked at the coffin in front of him.

The coffin without runes seemed to have no other strange feeling except big. The feeling of depression that came from the coffin itself gave Tang Yu was also gone because he had been by his side for so long.

"Can't it be said that the first level of test is not just about comprehension runes?" Tang Yu muttered.

"Master, Xiaoqi told me that the image of the thoughts left by the mistress did not seem to say how many tests are!" The voice of Lotus Lotus Rouge sounded in Tang Yu's sea of ​​consciousness.

"Uh! I'll let Xiaoqi out!" When Tang Yu heard the sound of lotus flowers and lotus bamboo, he felt strange and always felt like he was being monitored. So he entered the energy space and brought Xiaoqi out again.

"Xiao Qi, look at the current situation, how is it?" Tang Yu said, pointing to the coffin in front of him.

"Master, what's going on!" Xiaoqi looked at Tang Yu in confusion, not understanding what Tang Yu was saying.

"that is……"

"Bang!"

The coffin suddenly exploded, and the huge explosion directly shook the entire coffin into pieces.

I don’t know what wood this coffin was made of. Such a terrifying explosion just shook it into pieces and did not shake it into powder.

"Nothing!"

When Tang Yu saw the explosion of the coffin, he originally wanted to ask something, but now there is no need to ask anything else. He smiled helplessly at Xiaoqi, and then applied to look at the smoke and dust formed after the explosion of the coffin.

"Swoosh!"

"Crack!"

Suddenly, an iron chain burst out from the smoke and dust, and slashed at Tang Yu very domineeringly.

"It seems that this is the real test!" Tang Yu's eyes flashed with a cold light, and he flashed out in an instant, then placed Xiaoqi on the ground, took out the scimitar made by Tang Tang, and met him.

"Bang!"

Tang Yu's scimitar was fiercely seen on the iron chain. Although this thing looked like an iron chain, the material it refined was obviously not steel, and it was very hard. Tang Yu's scimitar hit it, and it only made a violent metal clash and a harsh spark sound.

"Bang!"

In an instant, Tang Yu felt a huge force on the iron chain, and rushed towards him, following the scimitar in his hand and rushing into his arms, trying to destroy his arms.

"snort!"

Tang Yu snorted coldly, pinched the scimitar's arm, and made a sudden move. A huge force instantly exploded from his body and rushed towards his arm. In an instant, it broke through the powerful force that rushed into his body, and at the same time it also shook his own sleeves into powder.

"cut!"

Tang Yu used a scimitar and slashed at the void and slashed at the chain.

A sword light rushed out of the curve and continued to expand. After approaching the chain, it became more than a hundred meters long.

"Clang!"

A terrifying roar suddenly rang in this space.

But unfortunately, the sword light did not have any impact on the chain. Instead, it broke into two instantly, looking very miserable.

"What is this iron chain?" Tang Yu frowned tightly, and was quite annoyed. The sword light shot out of the scimitar could at least kill ordinary magic weapons directly into scrap metal. Why did it get on this iron chain without any harm? Instead, it was broken into two halves by itself. This is too speechless!

"Boom!"

The knife light that broke into two halves continued to bombard it, half slashing towards the ground, and instantly tearing out a terrible abyss gully on the ground.

The other half was bombarded into the dust that appeared on the iron chain.

"Bang!"

After flying into the dust, the half of the sword light hit something, and it exploded instantly, making a roar of fear.

For a moment, the dust formed was blown away by the explosion.
Chapter completed!
