Lu Yu opened his mouth, took a big breath, and absorbed all the metallic aura in the air into his body.
After absorbing all the metallic aura, a faint golden light suddenly appeared around Lu Yu's body. From a distance, it looks like he is wearing a battle armor.
"These metallic auras are enough to save me half a month of hard work."
For this result, Lu Yu was also a little surprised.
Lu Yu practiced the skills of the ancient immortals, and it was much more difficult than other immortals to make progress in the energy of the five elements.
"It seems that the previous auctioneer was right. This is the best gift for the disciple."
Lu Yu noticed that there was another formation beside him.
Although these metallic tigers are powerful, they cannot leave the range of the cave.
If it is really the later disciple of that Taoist monarch who broke into here and finds that he is invincible, he can also leave temporarily to avoid the edge.
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 continued to walk towards the passage behind the door without any hesitation.
Walking through the passage, one or two tigers still appeared, but they were not Lu Yu's opponents, and they were killed one after another.
Suddenly, the front of him suddenly opened up, and an independent space appeared in front of him.
There is a little more light here, but it is not produced by candles, but the cold light and stars gathered on the long sword.
Fantie will reflect light only where the sun shines. But for some fairy artifacts, even in places where there is no light, it can still release dazzling light.
These long swords gathered to form a tall long sword platform, on which sat an old man.
The figure of the old man was a little illusory, and he didn't look like a real person. When he saw Lu Yu walking in, he suddenly opened his eyes.
"Play chess." The old man said only two words.
Lu Yu frowned, and he glanced around.
The formation here is more complicated than before.
Even if it is him, it will take a certain amount of time to crack this formation.
However, the sudden appearance of the old man aroused Lu Yu's interest.
"Are you the spirit of this formation?" Lu Yu asked.
The old man still had no expression on his face, just repeating the same sentence: "Play chess!"
"Want to play chess with me? That's fine." Lu Yu walked up to the old man without further ado.
In front of the old man, there is an iron plate with a chessboard drawn on it.
However, there are no chess pieces.
The old man remained silent, as if he was waiting for Lu Yu to settle down first.
"This chessboard is a bit interesting." Lu Yu just took a look at it, and he noticed the traces of countless formations.
Even, there is a small world inside.
This is the same as his Beidou Tianzong storage bag, there is another universe inside.
Lu Yu put his consciousness into the chessboard, and everything in front of him suddenly became clear.
This is a boundless land of yellow sand, and the chess pieces that Lu Yu has mastered are all soldiers in black armor.
On the opposite side, there were roughly the same number of soldiers standing upright, also holding sharp swords.
Lu Yu's position is on the platform of the black-armored soldiers, with several black-armored generals on both sides.
These soldiers are alive and well, but they are dead silent.
"I understand. If you want to win this set of flags, you must eat the opponent on this battlefield!" Lu Yu glanced at the surrounding formations, and a flash of understanding suddenly flashed in his eyes. (Remember the site URL: www.hlnovel.com
