Although the origin of this ancient castle in the deep mountains is unknown, and he doesn't know whether it is a human or a monster living inside!, Xiao Yu still decided to try his luck, even if the ancient castle is dangerous, he still has a purple gold gourd and a chaotic space to hide.

Soon, Xiao Yu flew over the castle, around the castle a few times, the castle is unusually quiet, the quiet is terrible, Xiao Yu probed out his sense to explore the inside of the castle, the structure of the castle is very complicated, unlike the magnificent castle built by some other nobles, the interior of this deep mountain castle is composed of many narrow corridors and dark and damp stone chambers. There was not a single figure in the castle of Nuoda.

Xiao Yu landed in front of the gate of the ancient castle, and was about to break in, when he heard an old voice behind him, "Guest officer, do you want to spend the night?"

Xiao Yu's pupils shrank slightly, and he quickly turned his head to look, only to see an old man with gray hair and a serene face walking up from the steps down the mountain with an ebony cane in his hand. The old man looked very slow, and it was difficult to take a step, but in fact, it was extremely fast, but he walked in front of Xiao Yu in just a few steps.

What is the reason for this? Xiao Yu wondered in his heart, obviously looking at the old man even had a hard time walking, but the speed was amazingly fast, not the speed of walking, but the time it took him to walk up the mountain from the bottom of the mountain was very short, as if he had crossed a large space in one step, obviously it took five hundred steps to walk up, but he only used a hundred steps, or even less!

"Do you want to stay overnight?" The old man looked at Xiao Yu with kind eyes and said with a smile, "Only me and the old housekeeper are in our village, and there are many rooms, if the guest officer wants to stay overnight, just stay!"

Xiao Yu secretly strengthened his vigilance, this old man came too suddenly, just now he used his divine sense to sweep the surrounding dozens of miles, and did not find the existence of anyone, but this old man suddenly appeared here, obviously extremely abnormal.

"Butler, butler!" cried out the kind old man as he approached the gate of the castle with a staggering step. The voice is old, but it is very loud, and it can be heard that the old man is very confident, and he is a healthy old man.

"It's the old man who is back!" After a while, another old man slowly opened the gate of the tall castle and walked out with staggering steps, the old man's eyes were dizzy, his body was thin into a bamboo pole, goosebumps, and he looked like he was decrepit with half a foot in the coffin.

"Has the old man come back from his visit?" The old butler tried to open his cloudy eyes, trying to see the person in front of him clearly, but it was too dark outside, although the castle was brightly lit, but it was difficult to hide the night outside, and the old butler's eyes couldn't even see it. So he took a few more steps forward.

"It's me, old butler, I'm back," the kind old man put his hands on the old butler's arm, and smiled kindly.

"It's really the master who is back! It's good to be back! It's good to be back!" the old butler nodded again and again, and his mood became better.

"Old butler! There is a guest in the castle, this young guest officer wants to spend the night, you go and make him a pot of tea, and then prepare some dinner, this has been running here again and again, and this guest officer is also tired of coming here, so arrange for him to rest earlier" The kind old man arranged the old housekeeper, and nodded to Xiao Yu friendly, "Young man, the old man has just come back from going to Xieyue City, and he is too tired to run for days, so go and rest first, you can take care of yourself, just your own home at that time, you don't have to be polite"

"There is an old man!" Xiao Yu thanked him, no matter whether he was true or not, Xiao Yu thanked the old man, even if he waited for the soldiers to meet each other, it could be regarded as a salute before the soldiers. Xiao Yu didn't think that this old man was really a good man who was about to die, and he was able to trek from Shura Mountain thousands of meters down, without panting, without seeing his body weakness, which shows that the other party is also a person with cultivation, and the other party deliberately pretended to be an old man who was going to die, which must have a purpose, perhaps just to paralyze Xiao Yu.

Xiao Yu has repeatedly probed these two old men, and he can't see any mana fluctuations, which explains the problem, either the other party is a mortal who doesn't know how to practice, this possibility can be directly ruled out, and there is another possibility, that is, cultivation is far better than Xiao Yu, this possibility is very high, therefore, Xiao Yu has to cheer up his spirits.

After the kind old man left, Xiao Yu was arranged by the old housekeeper to rest in a side hall of the ancient castle, and then the old housekeeper went to the kitchen to boil tea, Xiao Yu has always left a trace of consciousness on the old housekeeper, silently monitoring the old housekeeper's every move, out of the side hall, walked through a long corridor, entered the kitchen, and then began to boil water meticulously, and did not see the old housekeeper have any abnormal behavior.

Xiao Yu couldn't help but be a little puzzled, it was very good to do it in the tea, but the old housekeeper didn't do it, did he want to do it in the meal?

The old housekeeper's movements and expressions were very serious, as if a craftsman was carving a beloved work of art, adding firewood and water until the water was boiling, and then the old housekeeper went to the next room to get tea leaves and tea sets, and finally walked back to Xiao Yu's room with tea.

There was nothing suspicious from beginning to end, Xiao Yu almost thought that the other party would not do anything in this link, who knows, just when the old housekeeper walked to the door of the side hall, the old housekeeper suddenly lowered his head, and instantly revealed a pair of sharp fierce teeth, like a long beak, the fierce teeth were gently touched in the tea, and a colorless and tasteless liquid flowed into the tea.

The old housekeeper walked into the side hall as usual, brought the tea tray to Xiao Yu, poured a cup of tea for Xiao Yu, and then handed it to Xiao Yu, "There is no good tea in the mountains, only this frozen oolong chat to quench your thirst, little brother, don't blame!"

Xiao Yu raised his head to meet the strange expression of the old butler who seemed to be smiling but not smiling, and suddenly understood in his heart, this is the meaning of watching himself drink poisonous tea? If he does not cooperate, the other party is very likely to come hard.

"The old housekeeper has worked hard! Why don't we sit down and have a drink together" Xiao Yu took the teacup handed over by the old housekeeper, and casually poured a cup for the old housekeeper and handed it over.

The old housekeeper was stunned for a moment, and waved his hand again and again: "The little brother is polite! The old man is a subordinate person, how dare he drink with the objectivity! If the old master sees it, he must drive the old man out, and he must not do it.

"Hmph, are you afraid of being poisoned together?" Xiao Yu forcibly stuffed the teacup in his hand into the old butler's hand and sneered.

"Why did this young man say that?" the old butler's face changed instantly, and he wondered.

"It's not okay to be an idiot!" Xiao Yu sneered, "If you don't want people to know, unless you don't do it, when you entered the door, I already saw you use your bat-like beak to poison Lao Tzu's tea, what else do you have to say?"

"What? do you see?" the old butler's cloudy eyes suddenly rolled, and a fine light flashed, and his rickety body quickly became taller, and he was a sturdy old man, where was half old and weak.

"Hmph, what do you say?" Xiao Yu flipped his palm, quickly held the iron gun in his hand, and pointed coldly at the old butler.

"Haha! Since you can see it, you can only use it" The old butler's tone changed suddenly, and he turned his palm into a knife and slashed at Xiao Yu obliquely. The powerful energy true qi set off a strong wind, causing Xiao Yu's face to ache.

"Then it depends on whether you have the ability to do this!" Xiao Yu's momentum changed suddenly, and the whole person looked at the old butler coldly and indifferently like a killing god, and the spear in his hand was impartial, stabbing the old butler's face door, and the bean-sized point on the head of the gun compressed the earth-destroying energy and locked the old butler tightly.

"Peng!" The old butler slammed his palm on Xiao Yu's spear head, and the big black dot immediately burst open, and the powerful energy shock wave spread out like water ripples, and the nearby room was immediately destroyed. However, the castle was able to open its shield in time and remove most of its strength, so it was not destroyed.

Xiao Yu and the old housekeeper were shocked out at the same time, but they each stabilized their bodies with their strong strength.

"Quack! Good boy, you have some ability! No wonder you dare to enter Shura Mountain alone!" the old butler steadied himself and said with a smirk.

"It's easy to say!" Xiao Yu thought in his heart, judging from the other party's skills, his strength is far better than his own, and his cultivation should be above the merger period, if he fights alone, maybe Xiao Yu will be able to win the other party with endless means, but he is not alone here, and there is an old master with unfathomable strength, which makes Xiao Yu quite jealous.

"Eat me again!" The old butler snorted coldly, his figure suddenly shook, and the afterimage of his body pounced on Xiao Yu, and the powerful force rolled towards Xiao Yu again.

"It's a good time!" Xiao Yu secretly praised, the Yang Divine Technique in his body worked sharply, and the iron gun in his hand quickly swept towards the old butler.

The old housekeeper also sensed the danger from Xiao Yu's sharp marksmanship, and he didn't dare to greet Xiao Yu rashly with his bare hands, especially the black spots that flashed at the head of the gun all the time, the old housekeeper was quite jealous. With his powerful cultivation and speed, he circled with Xiao Yu.

Xiao Yu's body did not move, his eyes were slightly closed, and he quietly felt the movement around him, no matter what fancy movements the old housekeeper made, Xiao Yu was unmoved, only quietly waiting for the other party's flaws, trying to kill the opponent with one shot.

The old housekeeper tentatively made several fake attacks, but they failed to attract Xiao Yu's attention, and he felt very troubled.

The old housekeeper was waiting for Xiao Yu's flaws, Xiao Yu was also waiting for the old housekeeper's flaws, the two sides had been at a stalemate, and in the end, the old housekeeper couldn't help but take the lead in making a move against Xiao Yu.

The old housekeeper flicked his sleeves, his whole body was full of true qi, and he pounced on Xiao Yu like lightning against the body protection method, this was the rhythm that he wanted to directly crush Xiao Yu with his powerful cultivation.

The corners of Xiao Yu's mouth curled up with a cold curve, what he wanted was this opportunity, Xiao Yu's eyes opened, and the iron gun in his hand faced the old butler in an extremely slow posture, it seemed that the speed was extremely slow, but in fact it was as fast as lightning, breaking through the limit of speed in an instant.

"Ahh
