"Mr. Yang, what's the matter?" Anne also looked at Yang Fengdao.

"I see that your heaven and earth aura in the western realm is very thin, and it is very difficult to obtain the energy needed for cultivation from the outside world, why does your true qi and your magic elements seem to be inexhaustible, and they are not commensurate with your current cultivation? Also, your thunder and lightning skills don't seem to be high-end skills, why can you easily kill these undead creatures?"

"I'll answer the second question first, it's very simple, the bodies of these undead creatures and the armor on their bodies are good conductors of electricity, so they can be easily killed with the discharge technique!"

"Good conductor?" Yang Feng was stunned again for a while. He didn't know that people in the Western world like to delve into "materialization", so they naturally created some terms on "materialization". These terms are naturally new to Yang Feng, and they can't be understood for a while.

However, after all, Yang Feng was a person who had been a qi refiner, and he still had the ability to draw inferences from one another, and he could only use the Five Elements Method to deduce that these undead creatures might be wind attributes, and the thunder was the one that was the wind receptacle! Next time, he would also use the thunder and lightning technique to overcome these undead creatures. Isn't the Spirit of the Thunder Dragon that Zhao Xueqin lent to him still on the Doumen Divine Sword? Now it's just that he lacks enough True Qi to trigger it.

"What about the first question?" Yang Feng was still eager to know the answer to the first question.

"The answer has already been told to you, this is it!" Anne smiled, pointing to the blue medicine in her hand.

It turned out to be just drinking blue medicine!

Yang Feng was stunned for a moment and suddenly realized: This Western Realm Heaven and Earth Spiritual Qi is so thin, what else can be done except to constantly drink blue medicine to increase the accumulation of true qi in the dantian? But how can this blue medicine be obtained? Could it be that we can only rely on beating these undead creatures? Then how can there be so many undead creatures? Even if the number of undead creatures is large enough, they must all be in the catacombs everywhere, is it possible to dig graves everywhere? Then there is no need to do other things?

Yang Feng still said the question in his heart.

"Let's talk as we go. Anne said.

So the two of them left the underground cave hall and continued to walk forward. Anne answered Yang Feng's question as she walked: "There are many ways to obtain elemental potions, you can generally buy them in the alchemist's shop, you can also get them from monsters, you can also buy raw materials, and process them in the laboratory according to the recipe yourself......"

"I see. Yang Feng nodded.

At this point, the tunnel was already at the end of the tunnel, and there was no door or other exit in sight. When Yang Feng was puzzled as to why there was no way, a little flame escaped from Anne's hand, and with a wave of her fingers, she flicked the flame to a stone candlestick inserted in the wall on the right, and there seemed to be a half-cut candle standing on the candlestick. The flame that popped out was falling on the wick of the half-cut candle, and the half-cut candle suddenly re-ignited the flames-Yang Feng was in a daze, the wall in front of him "suddenly" sounded, and then slowly opened a stone door.

"There will always be mechanisms in these catacombs, don't give up when you get to the end of the road, you can open the door if you find it. However, there are some traps that cannot be opened at will, otherwise they will trigger hidden weapons or traps!" Anne explained.

After going out of this stone gate, I walked a short distance to the bottom of a dry well, and there was a long wooden ladder against the wall, which seemed to be the exit. Yang Feng understood that after going out from here, a fierce battle was inevitable, and he pressed the hilt of the Doumen sword with his hand, and his eyes lit up with war intent!

However, he had a trace of melancholy, after all, the reserve of true qi was not enough, and it was obviously impossible to rely on the power of cultivation to kill happily, so he could only rely on his enthusiasm to fight hard!

"Mr. Yang, you quickly take this potion, its effect can last for fifteen minutes, I hope we can end the battle within fifteen minutes!" At this time, Anne handed a small crimson bottle to Yang Fengdao.

"This is ......," Yang Feng showed an inquiring look in his eyes.

"It's an invisibility potion, and it can temporarily hide your traces - we must hide them when we enter the castle this time, and alert the enemy as little as possible!" Anne said.

"Can this thing really be invisible?" Yang Feng laughed first after asking this sentence, in the world of cultivation and magic, what is impossible?

"Hurry up and prepare, Tolloff should live in the secret room at the top of the castle, let's clear the enemies in the courtyard first, after the enemies in the courtyard are cleared, I will go up from the south tower, you go up from the north tower, and finally meet at the door of the secret room!" Anne said, taking a bottle of invisible medicine, and then the person disappeared from Yang Feng's eyes, and there was a slight noise from the top of the wooden ladder, it seemed that she had gone up first.

Yang Feng also hurriedly took the invisibility medicine, and a faint strange halo suddenly appeared on his body - this should be the effect of the invisibility medicine, but this halo should only be seen by himself, because he did not see this halo on Annie's body.

Yang Feng also climbed up the wooden ladder, and after going up for three or four zhang, he reached the ground. It was already dark outside, and the place where he came out was close to the base of a city wall, and there was a corpse on the ground in front of him, which had been killed by someone who had cut his throat!

There are indeed two towers in the distance, and the two towers are connected by a bridge to the main building in the middle, and the secret room must be at the top of the main building.

When Yang Feng didn't know which way to go, suddenly there was the light of torches nearby, and the sound of people talking. Yang Feng looked at it, and it turned out to be two people wearing black robes, wearing strange headbands, and strange three-foot-long scimitars hanging from their waists! These people were undoubtedly witch hunters!

Although Yang Feng was invisible, they couldn't see Yang Feng, but Yang Feng still cautiously walked behind them, and then swung the Doumen Sword twice in a row, sending the two to see Grandma!

After the attack was successful, Yang Feng discovered a problem. It turns out that the sword body of this Doumen is too long, which is more suitable for inducing sword qi to play its role like a mountain and a sea in a big scene, and it is not conducive to this kind of close-range assassination action, and the weird scimitar on the witch hunter is more suitable!

Yang Feng immediately put the Doumen Sword on his back, and then picked up a witch hunter's scimitar......

Just now, these two people came from the direction of the tower on the right, it seems that they didn't touch Annie, then this must be the North Tower! Yang Feng searched in this direction.

Along the way, he met several more witch hunters, all of whom were wiped by Yang Feng with the scimitar......

In a short time, he had reached the bottom of the tower. However, he circled the tower several times, but could not find the door. And the halo on his body has begun to flicker non-stop, and it seems that the invisibility effect is coming to an end!

At this moment, the slain person may have been discovered, and there were torches lit everywhere, and there were hoarse shouts!

The light also lit up in the tower in front of Yang Feng, and a door opened somewhere, as if someone had come out! Yang Feng immediately swept over there......
