The characteristics of Ji Ju Jiu Jian (Accumulated Rectangle Nine Swords) are its high attack frequency. Therefore, when paired with some simple stacking effects, the output is very powerful. Of course, this also requires combinations with other skills. Below, the editor will bring you a guide on how to play the Yan Yun Sixteen Sounds Ji Ju Jiu Jian build. If you still don't know how to play the Ji Ju Jiu Jian build, then you must follow the editor's steps closely. The following will provide a relatively detailed gameplay tutorial and skill acquisition guide.

I. Guide for playing the Ji Ju Jiu Jian build:
1. Martial Arts Combination: First, the martial arts include Ji Ju Jiu Jian and Nine Curves Spirit Lance.
2. Heart Methods: Carry Si Shi Wu Chang (Four Seasons Unpredictable), Yi Shui Ge (Yi Water Song), Jian Qi Zong Heng (Sword Qi纵横), Suo Hen Nian Nian (Hate Every Year).
3. Special Techniques: Use Ling Yun Ta (Soaring Cloud Step) and Dog Mouth Snatch Food; others can be chosen at your discretion.
4. Equipment: Use Output Fly and Defense Eagle equipment.
5. Build Gameplay: First, Nine Curves Spirit Lance is a martial arts skill, while Chou Wu Jiu (Wineless Sorrow) stacks to increase blood damage by 15%, which is easier to trigger with six consecutive hits. Suo Hen Nian Nian can stack debuff effects on bosses, reducing target defense—a team-shared skill, but only one person in the team needs to carry it. If the team already has Suo Hen Nian Nian, you can change this to Ji Le Xue Qi (Extreme Bliss Blood Qi), avoiding stacking blood Qi and focusing on blood settlement damage. After carrying Jian Qi Zong Heng, Ji Ju Jiu Jian can unleash a sword pursuit during the perfect timing phase of the finishing move. If the target is under five layers of bleeding, all bleeding will be cleared and immediate significant bleeding damage will occur. Both martial arts skills and special skills can be easily triggered by continuous pressing after release. For charged skills, do not immediately press after sheathing the weapon, as this can easily fail; more practice is required.

6. Operation Method: After starting the dungeon, click Ling Yun Ta, then use Dog Team Snatch Food to consume essence, followed by Nine Curves Spirit Lance martial arts skill. Switch to Ji Ju Jiu Jian using Yi Wu Skill, use martial arts skill and special agent, then use charged skill but do not charge too long or cause bleeding. Continue cycling attacks, repeat Dog Mouth Snatch Food, press Yi Wu Skill and Nine Curves Spirit Lance martial arts skill, switch back to Ji Ju Jiu Jian using Yi Wu Skill, then continue the cycle with Dog Mouth Snatch Food. This set focuses on bleeding and settlement, so quickly stack bleeding and settle. When fighting solo bosses or exploring normally without needing much output, you can replace Nine Curves Spirit Lance with an umbrella for healing and attacking.

II. Skill Acquisition:
1. Location: Players need to go to Qing He Yin Yue Mountain to obtain the secret manual. The editor will mark the specific location on the map for everyone.
2. Stealth Learning: After arriving at this place, there will be a mechanism that players need to use the You Long Key. You Long Keys can be obtained through stealth learning tasks, level breakthroughs, or stronghold treasure chests. After entering the mechanism, first defeat the first enemy, then go up the stairs. Players can stand in a corner and wait patiently. When he is about to discover the player, jump down immediately, then ascend the stairs and directly kill this person to stealth learn Ji Ju Jiu Jian. Of course, don’t forget to equip it after learning.

Above is the guide on how to play the Yan Yun Sixteen Sounds Ji Ju Jiu Jian build provided by the editor. The stealth learning of this skill is relatively simple, but remember to prepare a You Long Key before going to learn it, otherwise it cannot be done. Additionally, utilize speed stacking bleeding for output.
