The difficulty of this old man was beyond Wang Rui's imagination.

Originally, no one in front of him could block this sword, but the old man blocked it with sixteen strikes!

Its powerful defensive capabilities and that terrifying iron shield made Wang Rui feel powerless.

As a disciple of the Sword Sect, the sword in his hand is his only weapon.

He did not have any other magical assistance, nor did he know any formations or talismans.

The only thing Wang Rui relied on was the three-foot green sword in his hand.

However, when this sword that had once been invincible was blocked by the iron shield, he felt helpless.

The old man has eight such iron shields in his hands.

And because of these eight iron shields, Wang Rui suffered a lot.

At this moment, most of his armor was covered in gray.

And in the gray covered area, his body began to become gradually paralyzed.

This old man not only has strong defense, but he is also an expert in using poison.

As soon as he blocked the sword, the other seven iron shields behind Wang Rui advanced several feet forward again.

At the same time, the surface of the iron shield will continuously spray out gray gas that corrodes into the air.

Even though Wang Rui had held his breath and used his spiritual power to isolate the gray mist, the gray mist was still eroding his body bit by bit.

The next moment, the old man stepped forward and punched the iron shield in front of him.

It was as if a huge bell was struck.

A loud bell sound suddenly burst out from the iron shield, and the other seven iron shields continued to reflect the sound waves, making all the sounds gather on Wang Rui who was in the center of the formation.

Wang Rui's face was pale as he guarded his spiritual platform carefully, with his spiritual power protecting his body, and at the same time he jumped up.

However, just as he jumped up, an iron shield suddenly fell from mid-air, hit him hard, and knocked him back to the ground.

This iron shield has not just eight sides, but nine!

Wang Rui spat out a mouthful of blood and became extremely angry.

Originally, he should have killed the immortal in the City Lord's Mansion at this time.

As a result, he was now stopped by an unknown old man and was unable to move forward or backward.

Even he felt that the sword in his hand was not worth it.

If an unknown old man is so powerful, how powerful should the immortal species be?
