After Gu Xiaowu returned to his attic, he began to use the collected elixir to continue to accumulate mana, and at the same time used suitable cultivation materials to strengthen his 'imitation spirit acupoint', hoping to break through to Chengdan as soon as possible.

After ten days, the deacon of the sect found him and brought him to Ouyang Hong of the Stone Castle, and the matter of the resource vein finally came to fruition. Ouyang Hong didn't explain much, and directly handed over a token and a golden deed paper to Gu Xiaowu, on which a phoenix was drawn on one side and the word 'sound' was engraved on the other, and on the other deed paper was written 30 million in the Nine Sound Valley Transmission Palace. Although Xiao Wu had never seen these two things, he had learned about them from the information sent by Kou Yuhuan, which were the forbidden token for entering the cave of a secret realm phantom sound cave mastered by Jiuyin Valley and a sect spirit stone exchange deed paper. Xiao Wu was very surprised, he didn't expect the rewards of this sect to be so rich, especially the Phantom Sound Cave Secret Realm, I heard that although it is not a large resource and a single resource, it has the effect of honing the Dao Heart of the Condensing Soul disciple to get rid of the demons in the heart, and there is also a special kind of Phantom Sound Yuan Crystal is a cherished advanced Cheng Dan material, but those who can enter it must be a disciple who has a certain identity and has contributed to the sect.

Ouyang Hong saw the surprise on Gu Xiaowu's face, waved his hand and motioned for several deacons around him to leave the main hall, and said to Gu Xiaowu: "Have you seen Kou Yuhuan? Today, I warn you again that before Kou Yuhuan becomes a Dan and enters the Dao, if you contact her again, I will destroy you directly. Leave me your Phantom Cave Token, and you must make amends for your mistakes. ”

Gu Xiaowu was dumbfounded, this Ouyang Hong still knew about his encounter with Kou Yuhuan in the Five Spirits Realm, he promised not to meet at that time, since he was discovered, he could only bear the consequences. And listening to this Kou Yuhuan's master, Kou Yuhuan should have committed some taboos, I really hope that it will be fine, he really has to pay attention to it in the future, don't bring disaster to his companions without knowing it, and immediately Gu Xiaowu honestly returned the token in his hand to Ouyang Hong, and at the same time repeatedly promised that he would never meet Kou Yuhuan again in the next thousand years. With thousands of years of cultivation, it is estimated that Kou Yuhuan has already become a Dan, and he should also become a Dan, so he is not afraid of Ouyang Hong's opposition at that time.

Xiao Wu walked out of the main hall in a gloomy mood and left the stone castle and returned to his attic, but within a few days, he received an order from the sect, ordering him to follow a group of disciples back to Santuoling. Of course Xiao Wu will not object, he originally had a plan to return to the sect, and it will not take long to be arranged to return to the sect when he returns to the Santuoling Fortress, and he already has the sect deed paper of 30 million spirit stones in his hand, and there will be no shortage of spirit stones and cultivation resources in his future cultivation.

It's a pity that the dream is a beautiful reality but it is very cruel, he actually returned to Santuoling and was taken to another huge black city not long after, the Black Wind Mountain Fortress of the Iron Sword Gate that was rumored to have been destroyed!

Gu Xiaowu thought that this matter must have something to do with Ouyang Hong, because at this time, Ouyang Hong also appeared in the Black Wind Mountain Fortress Black Wind City. Gu Xiaowu stood on the Nine Sound Valley Battle Boat that was still floating in the air and looked around, this time there were really a lot of Nine Sound Valley disciples who were arranged here with him, there were more than five thousand people, and he was a little skeptical that Jiuyin Valley had given up Santuo Mountain and chosen Black Wind City. In the end, the disciples who arrived in Black Wind City in the Nine Sound Valley were all scattered and arranged to rest in the black stone buildings in various places in the city, waiting for the dispatch and assignment of the following sect tasks.

Gu Xiaowu honestly stayed in an attic for a long time before someone came to visit, it turned out to be two fellow disciples who were assigned to the same attic, and the three of them quickly got to know each other and exchanged information, and finally exchanged information in their hands. Only then did Gu Xiaowu know that more than 4,000 of the 5,000 condensing spirit disciples who came to Black Wind City had just arrived in the wilderness not long ago, and this time Jiuyin Valley was ordered by the Tianyin Academy to directly mobilize 10,000 condensing spirit disciples from the sect to support the fortress, of which more than 5,000 were used to replace the disciples on the other side of the Santuo Mountain fortress, and the remaining more than 4,000 were brought to this Black Wind City with people who were transferred from various small strongholds and fortresses.

He generously gave each of them a copy of the intelligence information he had collected about the wilderness and the nearby area, and with this information, the two of them would feel more relaxed, just like when he first bought a piece of information. The two Ning Ling are not young, one is three hundred years old and the other is five hundred years old, they are all disciples who have no plans to retreat and do penance, they didn't expect to receive an order from the sect three years ago, and at that time it would be disobedient to the sect if they wanted to retreat, but fortunately, it was already stated that as long as they completed the thirty-year guard task, they could go back, and the people who were disrupted had to prepare for a while and then came to the wilderness.

Gu Xiaowu was also very surprised, this Iron Sword Gate was hit hard and went back to recuperate, shouldn't Jiuyin Valley send people to the top, no other sect can come over? Taking over this fortress will also take over the nearby resources, and the benefits are not small, besides, the Iron Sword Gate has only lost more than 10,000 people, so it won't even be reluctant to ask for the fortress, right? And the number of condensing disciples that can be mobilized in the Nine Sound Valley is also limited, and there should not be many people guarding the mountain gate now, after all, there are forty condensing disciples who are in retreat and penance, otherwise where can one Cheng Dan be produced a year to provide to the Tianyin Academy.

The question in Xiao Wu's heart was quickly answered, it turned out that the Iron Sword Sect suffered heavy losses this time, although five elders and 10,000 disciples were sent, but it was not enough to carry out the task smoothly, so he thought of borrowing people from the Nine Sound Valley, so he proposed it to the Tianyin Academy and the Nine Sound Valley. Tianyin Academy is naturally willing to deal with this kind of matter involving the distribution of interests of the sect easily, and then asking other forces to intervene in the Blood Sand Mountain Range will cause a lot of entanglements, so it agreed to the Iron Sword Gate's request and ordered the Nine Sound Valley. The elders of the Nine Sound Valley agreed as soon as they agreed, so they increased the quota of five thousand reinforcements to the wilderness three years ago, and deliberately forcibly recruited hundreds of disciples who had not yet retreated in order to make up enough numbers.

The seconded disciples of the Nine Sound Valley were quickly divided into three units, one thousand people were responsible for the reconstruction and defense of Black Wind City, two thousand people were responsible for guarding and collecting resources for a stronghold thousands of miles northwest of Black Wind Mountain, and the other two thousand disciples were responsible for the construction and expansion of a stronghold thousands of miles away in the southeast. At this time, Gu Xiaowu was standing on a sect warboat and rushed to the small stronghold to go this time, and next to it there were three or four people sighing for their bad luck, not long ago, the two elders of Jiuyin Valley asked their five thousand disciples to draw lots to decide where to go to the guard, and finally the disciples on this battleboat were drawn to rebuild the small stronghold in the southeast and collect exploration resources.

The easiest of these three tasks is the construction and protection of the fortress, which has been rebuilt in a large area by the Tenyin Temple. In addition, the stronghold in the northwest is also a very safe location, it is the only stronghold of the Iron Sword Gate that has not been destroyed by the attack, and it has been managed by the Nine Sound Valley at this time. And Gu Xiaowu is going to a more dangerous stronghold, no wonder many people complain about the abnormality, but Gu Xiaowu doesn't care about this, what he cares about is why Ouyang Hong is still on this battleship, she is actually the elder who led the team to establish a stronghold in Jiuyin Valley this time, this is too coincidental, right?
