You...... Who are you? ”

Hearing this, Tang Ye and the others suddenly turned around and saw that a woman on the bed had woken up.

Tang Ye's body moved violently, and he suddenly came to the woman, and without waiting for her to say another word, he hit the opponent's neck at once, knocking him unconscious, and then gently put it down.

Such a small episode did not affect Tang Ye and them, and at this time, Yang Ke suddenly found a book from the drawer and handed it to Tang Ye.

Tang Ye saw that there were four big characters written on the cover of the book: "Green Pine Swordsmanship"!

Without looking too much, Tang Ye directly threw it into the system, and then they found some pearls and jadeite and other items under the bed, and Tang Ye threw them all into the system.

Of course, one of the tokens made of special metal aroused Tang Ye's interest. However, they didn't study or linger too much, and left the city lord's residence directly.

I have to say that having an invisibility cloak can indeed enable Tang Ye, a fifth-level powerhouse, to do many things that he couldn't do before. Infiltration and assassination couldn't be easier.

Of course, it will certainly be easier at first, but then the assassination will not be so easy if the enemy is prepared.

After that, the three of them left the City Lord's Mansion and began to move towards the peak of the mountain not far away.

It was a mountain hundreds of meters high, and at the foot of the mountain was surrounded by a high wall, which was about the same height as the wall of the city lord's mansion, but it was guarded by a soldier almost five meters away, and the guards were even stricter than the guards on the city walls.

This made Tang Ye more and more curious about the secrets hidden in it.

The high wall was about five meters high, and when Tang Ye and the three of them came to the wall incognito, Tang Ye was about to climb when he was suddenly pulled by Guan Li behind him.

"Slowly, as far as I know, these walls are not ordinary walls. If you make hasty contact, you are afraid that you will be attacked! Guan Li said with a serious expression.

Hearing this, Tang Ye silently retracted his hand and began to carefully look at the wall in front of him, and indeed found something wrong.

The wall in front of him actually emitted a strange streamer in the night. Tang Ye was extremely surprised in his heart, and then he said that the wall extended to both sides, only to find that there was a lightning rod-like needle at the top of the wall not far away.

"Could it be that the guiding thunder is all over the walls?" Tang Ye asked in a low voice in surprise.

Guan Li nodded in admiration: "The lord is really knowledgeable!" You're right, this is indeed a thunderbolt wall, but it's not a thunderbolt, they don't have that ability, but the thunder element in the air to achieve an approximate effect.

"Only by going through the special door or turning off the switch can you avoid the attack of the lightning element, otherwise even if the insulator touches the wall, I am afraid that it will be burned to ashes in an instant."

Tang Ye nodded, revealing a look of understanding, and then he sighed lightly and said, "

I didn't expect that the machine technique had advanced to this level. This is a great technology that can rule Yunzhou! If it weren't for me, I'm afraid that even Liu Pei's guy would have been defeated by Zheng Jin's men sooner or later. ”

After sighing, Tang Ye began to think about how to cross the wall.

"If I destroy those needles, will I be able to invalidate the walls, even if only for a moment?" Tang Ye asked Guan Lidao.

But Guan Li shook his head: "No." ”
