Lu Yi finally agreed to Nangong Yuxin's request, because Nangong Yuxin's words also caused some resonance with Lu Yi, although he didn't stay in the alliance headquarters for a long time, he also witnessed a lot of factional struggles, which is also a point that makes Lu Yi very worried, the big enemy is current, but those people are still fighting infighting, and almost all their energy is focused on fighting for power and profit, how will such a state face the offensive of the demons in the future?

In stark contrast, the approach of the Western Regions Righteous Alliance is just the opposite, the righteous alliance is unprecedentedly united, united from top to bottom, and actively preparing for war, this contrast has touched Lu Yi a lot.

Fortunately, his family and relatives and friends who are closely related to him, such as Yaoshan in the Southern Regions, are not involved in too many disputes like the alliance, and they are also preparing for the second war between humans and demons that may occur in the future, which makes Lu Yi feel a lot relieved.

Therefore, Lu Yi understands Nangong Yuxin's hardships very well, and his impression of the Nangong family in the Eastern Regions has also changed a lot.

Lu Yi told Nangong Yuxin that his relationship with Gao Shan was not good, so he could only do his best, and whether he succeeded or not depended on the performance of Nangong Yuxin and the entire Nangong family.

Nangong Yuxin said that it was enough to have Lu Yi's words, and he would show the greatest sincerity to communicate with the three elders and the forces of the Huadu Plateau.

The two reached an agreement, Lu Yi left Nangong Yuxin's residence, and the two agreed to meet here again in five days, Nangong Yuxin will use these days to make final preparations, and when everything is ready, he will take Lu Yi to a secret place in Nangong's house to restore the mountain arrow.

In the past few days, Lu Yi has also stayed at home, and he is asking Venerable Li Tian for advice on how to repair a magic weapon in good condition.

Venerable Li Tian told Lu Yi that this is a very valuable job, and the magic weapon will inevitably be damaged during use, and it is usually difficult to obtain a new magic weapon, and the cost is often very high, so since ancient times, the monks have been studying how to repair a damaged magic weapon, and after so many years of accumulation, many magic weapon repair methods have been handed down, almost all of which are related to the formation.

The repair of the magic weapon is basically for the purpose of maintaining the original efficacy of the magic weapon, or slightly improving the effectiveness of the magic weapon through repair, such as this kind of repair of the magic weapon is exactly the same as the original thing is actually very rare, and it only happens in the complete set of magic weapons such as the broken cloud bow, the reason is because the complete set of magic weapons is often related to each other through the formation, and if it is not restored as before, the formation will be invalid, so that the effectiveness of the complete set of magic weapons will be greatly reduced, and the broken cloud bow is not because an arrow is broken and the magic circle associated with each other fails, causing the machine spirit to fall into a deep sleep？

In response to this problem, it was not without monks in ancient times to find a solution, the most primitive of which was to reconstruct the formation of the damaged part by referring to the original design of the set of magic weapons.

This is more decent, but because everyone has a different understanding of the magic circle, unless you find the person who cast the magic weapon and let him restore it by hand, there will definitely be a deviation if someone else takes over, and even if the repair is closer, it will be more or less affected, so that the connection of the complete set of magic weapons will sometimes be disjointed and the effect will be weakened.

Later, someone found a more perfect repair method, and recast the whole set of magic arrays on the original basis according to the original ideas, so that the association of the complete set of magic weapons will be smooth, and there will be no disjointed contact in the process of use, but the risk of recasting is also very large, and the whole set of magic weapons will be scrapped if you are not careful.

Later, there were more clever means, in the refining of the complete set of magic weapons, the method of dealing with the damage of the magic weapon was reserved, once the magic weapon was damaged, it could be repaired according to the reserved method, this means mostly appeared in the refining of high-level magic weapons, such as treasure weapons.

A high-level complete set of treasures like the Shattered Cloud Bow is also the kind of fragile attack long-range weapon, and it will definitely reserve a certain repair method, so Venerable Li Tian told Lu Yi that when helping the Nangong family repair the Shattered Cloud Bow, he must pay more attention to learning, such an opportunity is a once-in-a-lifetime opportunity, and it will be of great help to Lu Yi's improvement in the formation path and refining weapons.

Five days passed in a hurry, Lu Yi came to Nangong Yuxin's residence again as promised, and after the two finally confirmed, Nangong Yuxin led Lu Yi to teleport out of Yunhua City to a small valley, where there was a secret place built by the Nangong family dedicated to alchemy refiners.

Yunhua City is too small, and once the alchemy refiner, especially the high-level alchemy refiner, causes a mistake and causes a fryer, the harm caused is not small, and it is not suitable to be carried out in the city, so the Nangong family chose such a small valley outside the city alone to arrange the clansmen to carry out alchemy refining activities.

In order to repair the mountain arrow today, Nangong Yuxin also notified the clansmen here to evacuate a few days in advance, and cleared the place, firstly, to ensure that no one disturbed, and secondly, to be afraid of an accident and hurt the innocent.

There was no one else in the entire valley except Nangong Yuxin and Lu Yi, Nangong Yuxin handed a simple jade slip to Lu Yi, and said earnestly: "This is a detailed explanation of the formation diagram of this Cloud Shattering Bow Treasure, which records a high-level magic circle between the Cloud Shattering Bow and the twelve arrows, you first understand it, and I will reconnect a few pieces of the Mountain Arrow when I turn back, and after I finish, you need to re-engrave the magic circle on the Mountain Arrow so that it can be connected with the Cloud Shattering Bow and other arrows and the arrow pot." Although this formation is only a sixth-order formation, it is still relatively difficult to comprehend, and this formation is very ancient, which is somewhat different from the mainstream formation in the current continent, which is also one of the reasons why the old man wants to find a higher-level formation mage to complete this work. However, since God let your kid appear with the family relics, it seems that there is a providence in the dark, and the old man has an intuition, you will definitely be able to do this!"
