"I see!"

Yang Yun understood that he underestimated the demon seed of the King Continent, and it could suppress the heroes and powerhouses of the human race, and let the human race build the Western Regions defense line and the Great Wall Guards to resist the invading demon seed forces, it could not be so simple.

At present, the soldiers and horses attacking Thousand Cave City are only partial divisions of the demon army. With most of the siege equipment lost, even if Yang Yun was asked to command this army of troops and horses, there was no other way to break through the city wall.

"If that's the case, then Thousand Cave City can still resist for a while!"

However, in the original timeline, Thousand Caves City was finally destroyed at the hands of the demon army, and from this point of view, the demon army must be secretly building siege equipment while attacking the city.

When the siege equipment is successfully built, the Thousand Caves City will no longer be spared.

Knock knock!

In the distance, there was a drum sound in the formation of the demon seed army. With the sound, the demon seed soldiers who were attacking the city began to retreat slowly, and the guards on the city wall suddenly breathed a sigh of relief.

"Finally survived!"

The guard captain beside him sighed. In the past few days, although they have relied on the protection of the city wall to kill many demon soldiers and monsters, they are also tired.

This time, relying on the arrival of Jia Luo and Yang Yun to boost their morale and repel the enemy, but next time, I don't know if they can survive the attack of the demon army.

At this time, the city wall was full of corpses, the blood almost pooled into a stream, and the smell of fish filled the city, and the guards and soldiers who had just been cheering up and shouting to fight sat down on the ground after the enemy retreated. and heedless the filth of the walls.

Dugu Xin, the city lord of Thousand Caves City, strode over, followed by Jia Luo.

Dugu Xin has a white beard and white hair, and looks very old, but his back is straight, his movements are fast and violent, and he can't see a trace of old age at all.

Dugu Xin strode over, laughed, and pulled Yang Yun towards a large hall in the city, ready to invite him to rest in the city, Yang Yun did not object, he was also ready to see the power of the secret demon path of the Thousand Caves City!

The Thousand Caves City is surrounded by mountains on both sides, and the peaks are extremely steep. Like a sharp sword piercing into the sky. Caves of all sizes have been carved out of the mountain walls, each of which holds a different type of book.

The Thousand Caves City also got its name from this.

Among these treasured books, there are the human geography of the King's Continent, the customs and customs, and the manuscripts of poetry collections circulated everywhere. As long as someone sends a book that has not been included in the Thousand Caves City, they can get a lot of rewards.

Over time, there are more and more books stored in the Thousand Caves City, which is all-encompassing. It even includes a lot of cultivation methods and martial arts Xuangong.

It can be said that in addition to the Imperial Taishi Museum of the Tang Empire in the east of the King Continent, Thousand Caves City has the largest collection of books.

Yang Yun followed Jia Luo's father and daughter into the city, at this time, the Thousand Caves City was affected by the flames of war, and it became a little chaotic, but when it was close to the library cave, a group of guards wearing heavy armor appeared to maintain order. Didn't let the chaos spill over to the rear.

"Young Master Chu, this time you helped the little girl, I can't repay it!"

Dugu Xin took Jia Luo and Yang Yun into the main hall, and at this time, the main hall had prepared a banquet, and there was no one else in the hall except for a few maids who served.

After the three of them sat down, Duguxin thanked him again.

"We don't have anything else in the Thousand Caves City, the most precious thing is the collection of tens of thousands of volumes, Master Chu, this is the token to enter the library cave, which allows you to read books in it for three days, this is my reward!

Dugu Xin took out a token from his body and handed it to Yang Yun.

Yang Yun's eyes moved slightly, and he glanced deeply at the Thousand Cave City City Lord in front of him. Although the other party has a smile on his face, his attitude is also very kind, and he looks very grateful.

But Yang Yun could feel that his gratitude and kindness were all disguised expressions.

Deep down, the other party is quite defensive of himself.

"Is this to enter the library cave to repay yourself for protecting Jialuo's favor?"

Yang Yun had such a thought in his heart, but his face was silent, he stretched out his hand to take the token, and said with a smile: "Thank you City Lord, I have always been curious about the collection of thousands of books in Thousand Cave City, and now that I have the opportunity to enter and read books, I am welcome!"

According to Yang Yun's knowledge, the power of the demonic path that Jia Luo cultivated came from the ten thousand volumes of books in the Thousand Cave City. If you look carefully, you may be able to peek into the secret of the power of the demon path from the books.

City Lord Duguxin's decision can be regarded as a great favor to Yang Yun.

After sensing that Dugu Xin was secretly on guard, Yang Yun naturally wouldn't use his hot face to stick to other people's cold butts, he didn't say anything to the other party, and after drinking twice as much wine, he got up and prepared for the guest room in front of him to rest temporarily.

Jia Luo didn't have so much thought, after entering the city together, her attitude became more intimate, and when she saw Yang Yun get up, she personally sent him to the door of the room.

Looking at the figure of Jia Luo turning away, a thought suddenly appeared in Yang Yun's heart.

"Eh, Dugu Xin is secretly guarding against me, such an attitude...... You don't think I'm a suitor of Garo, do you?"

Thinking of this, a trace of strangeness appeared on Yang Yun's face.

According to the normal situation, after he showed his incomparable strength, Dugu Xin, as the city lord, should be very happy to see the arrival of reinforcements, and try his best to win him over.

But the current situation is that the other party is defensive and kind on the outside, but there is not much enthusiasm in his heart.

Well, this attitude should have appeared after seeing Yang Yun flying to the city wall with his left hand holding Jia Luo.

Yang Yun's face twitched slightly. He did have some thoughts about Jia Luo, but what he wanted was to bring her over and act as a powerful subordinate to guard the Westward Journey World, and he didn't have many other ideas.

Of course, Jia Luo's stunning appearance and slender and straight legs are also very in line with Yang Yun's aesthetics......

"Forget it, my target is not this old man, his attitude and thoughts have nothing to do with me! Rest first, and then go to the library cave to find clues before the demon seed army attacks the city!"

Yang Yun closed the door, turned his heart to the sky, closed his eyes slightly, and began to run the exercises, transforming the original Hundred Poisons True Sutra and the Shangqing Heart Method cultivated by Chu Yuan into the all-encompassing Daluo Tiangong.

The second primordial god has not yet grown up, and the primordial god cannot exert the true strength of the earth immortal realm, and now he still needs to use Chu Yuan's physical body to enhance his strength.

In order to increase his strength as much as possible, it is inevitable to sort out the cultivation exercises and magic powers.
