All the demons are soldiers, and the low-level demons can be said to be endless, and they suffer a lot from the upper immortal cultivators, but the number makes up for everything.

Demons are similar to physical cultivation, with strong physiques and sharp reflexes, even if ordinary demons are only beaten on the ground, it is not so easy to kill them.

And after the number is too large, even a demon throwing a stone can also pose a threat to the immortal cultivators in the air.

The cultivation realm is equivalent to the high-level demons of the Yudan period can fly, and their combat power is very strong, and they can completely resist the powerful monks of the corresponding realm in the human race.

Therefore, although the immortal cultivators killed and injured many demons, they could not stop the spread of demons on the ground.

After a hundred years of hard fighting, close to the Fallen Demon Abyss, most of the Xingyuan Mountain Range was occupied by the demons.

Wherever the demons passed, both mortals and birds and beasts were devoured, and there were a large number of demons infiltrating into the hinterland of the Terrans, and any ordinary demons running into the towns of the Terrans would cause great damage, and these infiltrated demons would involve half of the Yuchen Realm in the flames of war.

Immortal cultivators come from ordinary people, without ordinary people, immortal cultivators will lose their foundation, if the situation continues to develop like this, the human race in the Yuchen realm will slowly lose blood and perish.

At this time, "Lianshan" and "Guanyun", the two great powers who were later revered as demon ancestors, thought of a way.

They were born in the Stargazing Sect of the Three Sects of Xingyuan, the Stargazing Sect is good at formations, and most of the mountain protection arrays of the various factions of the Xingyuan Mountain Range were established with the participation of the Stargazing Sect, and the two ancestors learned the way of the formation, and they were very familiar with these large arrays.

They infiltrated the Xingyuan Mountain Range, which had been occupied by the demons, and found the remnants of the three Xingyuan Sects' mountain protection arrays, which had been arranged over tens of thousands of years and had already penetrated into the spiritual veins of the Xingyuan Mountain Range.

The two great powers used the remnant array to detonate the main spiritual vein of the entire Xingyuan Mountain Range, and the Xingyuan Mountain Range collapsed, burying countless demons in one fell swoop, which turned the tide of the battle.

Seeing this, Chen Jingcai understood how the Shattered Star Hill was formed, and he had always been a little puzzled when he had seen the collapse of the Xingyuan Mountain Range in the Jade Jane that the Immortal and Demon War had fought.

Because it is not surprising that the great powers collapsed a few peaks in the battle, but it feels a bit exaggerated to collapse the entire Star Source Mountain Range and turn it into the current Shattered Star Hill.

It turned out that the two great powers of Lianshan and Guanyun used the mountain protection array of the three sects of Xingyuan to detonate the spiritual veins, causing the collapse of the Xingyuan Mountain Range.

Knowing this, Chen Jing suddenly felt that if the demon clan invaded again in the future, the Yuchen Realm would be a little worried.

After all, for tens of thousands of years, the strength of the immortal cultivators in the Yuchen Realm has not increased significantly, and now there is no means to induce the collapse of the Xingyuan Mountain Range that can determine the outcome of the victory.

But maybe, Chen Jing thought to himself, what he could think of, the powerhouses of the Yuchen Realm must have thought of it a long time ago, maybe they had already found an effective way to deal with the demon clan, but Chen Jing didn't know.

"Bell"

Outside the mountain protection array, the melodious jade bell in the welcome pavilion rang, and a visitor arrived outside the mountain.

Chen Jing put down the jade slip and thought to himself, it has been almost a month since the master broke through the middle stage of the Yuan Infant, and it is estimated that Tianchi Mountain, Motian Cliff and Huanglongling have all received the news, calculating the time, they should also come to hear the news, but I don't know who will come this time.

With a thought in his mind, his figure disappeared in place, and when he reappeared, he was already on the edge of the upside-down Five Elements Array closest to the welcome pavilion.

I saw a huge white eagle parked on the stone platform of the welcome pavilion, and the familiar Ah Bai came again, and there was a heroic young man standing in the welcome pavilion, it was Sun Lu of Tianchi Mountain, it seemed that he came to run errands and deliver letters this time.

"Senior Brother Sun, why are you here?" Chen Jing said with a smile.

Sun Lu was looking at the path stretching from the welcome pavilion to the mountain, but he didn't expect Chen Jing to suddenly appear from another direction, he turned his head and said with a smile:

"Senior Brother Chen, Master sent me to run errands."

"Hello Bai!" Chen Jing said hello to the giant eagle.

The huge white eagle chirped and nodded.

"Ah Bai has not been so polite to me." Sun Lu was a little surprised.

"Ah Bai and I are acquaintances, Senior Brother Sun, please come in!"

Chen Jing smiled, opened the big array to welcome Sun Lu closer, and asked, "Why didn't Senior Sister Fan Shuilan come?" ”

"Senior Sister Fan is cultivating on the mountain, and if she wants to go down the mountain now, Master will not agree."

Sun Lu didn't hide anything from Chen Jing, Zhuo Qingyun failed to marry the Dan and went to the Fallen Demon Abyss, such as the most promising disciple of Chishan today is Fan Shuilan, and he won't let her go down the mountain when he is idle.

Chen Jing took Sun Lu to the newly built guest house, and halfway through, he saw the little beasts running down the mountain to see Ah Bai.

The giant eagle Ah Bai has come many times, and he is familiar with the little beasts, except for Ah Bai, they rarely see other spirit beasts.

Sun Lu saw the little Qinglin beast he saw last time, a huge kitten, a fluffy and round chick, and a white fox following behind, running down the mountain all the way, to the edge of the mountain protection array, and greeted Ah Bai.

He is not very old, he is still very playful, and he is very interested in a few little beasts, but Sun Lu still held back, this time when the master sent him, he specially advised, or talk about business first, and then hurry back to the mountain to deliver the letter.

Chen Jing took Sun Lu through the lotus pond, walked up a few steps along the stone steps, turned onto a fork in the road, and came to the newly built State Guest House.

Although Chen Jing and Sun Lu have only met once, they are very close to each other and get along more comfortably, and the two sit down casually in the hall on the first floor of the welcome building.

"Senior Brother Sun, you came this time to ask me about Master's breakthrough in the middle of the Yuan Infant Period, right?" Chen Jing asked.

"Of course it's this matter, Senior Brother Chen, has Ling Shi really broken through to the middle stage of the Yuan Infant?"

Sun Lu stared at Chen Jing with blazing eyes, his master Pingbo Zhenjun sensed the abnormal movement of the spiritual energy between heaven and earth, and concluded that the Heavenly Wind Venerable had broken through the middle stage of the Yuan Infant, but Sun Lu was lowly and did not realize anything thousands of miles away, so it was inevitable that some people would be suspicious.

"Haha, my master has broken through the middle stage of the Yuan Infant."

Chen Jing's face was full of spring breeze.

“…… Admire! ”

Sun Lu's face showed a look of yearning, the higher the cultivation realm, the more difficult it was to break through, and the three factions of Tianchi Mountain, Motian Cliff and Huanglongling did not have a master in the middle of the Yuan Infant Period.

"The Venerable Master of the Heavenly Wind is out of the customs, I don't know if I can meet the little brother?"

Sun Lu asked, the disciples of the three sects have only heard of the Heavenly Wind Master and have not seen him, and when he came this time, Pingbo Zhenjun instructed him to meet the Heavenly Wind Master if possible, so that he could have a little understanding of the temperament of this master.

"Yes, now my master doesn't know where he went, and tomorrow morning, I will take you to see him."

Chen Jing agreed.

"That's great! Thank you, Senior Brother Chen! ”

Sun Lu was overjoyed, he also very much wanted to see this master who killed the Black Wind Old Monster as soon as he returned to Lingyan Mountain, and then retreated for twenty or thirty years, and broke through the middle stage of the Yuan Infant when he came out.
