Lu Yu opened his mouth and sucked it in a big mouth, absorbing all the metallic spiritual energy in the air into his body.

After absorbing all the metallic spiritual energy, a faint golden light suddenly appeared around Lu Yu's body. From a distance, it seemed like he was wearing a piece of armor.

"These metallic auras are enough to save me half a month of hard work."

Lu Yu was also surprised by this result.

Lu Yu practiced the martial arts of ancient immortals. It was much more difficult for other immortals to make progress in the five elements.

"It seems that the auctioneer said it well before. This is the best gift to his disciples."

Lu Yu noticed that there was a formation next to him.

Although these metallic tigers are powerful, they cannot leave the scope of the cave.

If it is really the disciple of the Taoist king who broke into here and found that he was defeated, he could leave and avoid the edge for the time being.

Of course, if you don’t even have the ability to escape, then there is nothing to say about dying here.

Thinking of this, Lu Yu did not hesitate at all and continued to walk towards the passage behind the door.

After walking through the passage, one or two tigers appeared, but they were not Lu Yu's opponents and were killed one after another.

Suddenly, the moment of enlightenment suddenly appeared in front of me, and an independent space appeared in front of me.

There is some more light here, but it is not produced by the fire candle, but the cold light stars gathered on the long swords.

The iron can only reflect light when the sun shines. However, for some immortal weapons, even in places without light, it can still emit dazzling light.

These long swords gathered into a tall long sword platform, and an old man sat upright.

The old man's figure was a little illusory, and it looked like he was not a real person. When he saw Lu Yu walking in, he suddenly opened his eyes.

"Trial game." The old man spoke, only saying two words.

Lu Yu frowned and he glanced around.

The formation here is more cumbersome than before.

Even if he wants to break this formation, it will take a certain amount of time.

However, the sudden appearance of the old man aroused Lu Yu's interest.

"Are you the formation spirit of this formation?" Lu Yu asked.

The old man still had no expression on his face, just repeating the same sentence: "Trick-up!"

"Want to play chess with me? It's okay." Lu Yu walked straight to the old man without saying anything.

In front of the old man, there was a chessboard drawn on it on an iron plate.

However, there are no pawns.

The old man remained silent, as if waiting for Lu Yu to make a move first.

"This chessboard is interesting." Lu Yu just took a look and noticed countless traces of the formation.

There is even a small world inside.

This is just like his Beidou Tianzong storage bag, with another universe inside.

Lu Yu fell into the chessboard and everything in front of him suddenly became clear.

This is a boundless land of yellow sand. The chess pieces Lu Yu controlled were all soldiers wearing black armor.

On the opposite side, there were also soldiers with approximately the same number of soldiers standing straight, holding sharp swords.

Lu Yu's location is located on the commander of the black-armored soldiers, and there are several black-armored generals on both sides.

These soldiers appeared vividly, but they were dead silent again.

"I understand. If you want to win this flag, you must eat the other party on this battlefield!" Lu Yu glanced at the formation around him, and a trace of enlightenment suddenly flashed in his eyes.
