忍术包罗万象，但是最基本的就是隐匿之术和逃遁之术，而这两类都有一个极为重要的方面，那就是改变容貌，甚至改变自的气息。

带着内力和气去诵唱的歌曲，又隐佛意，这对任何一个修行者，当喝的作用都是很大的。

许半生随后离开，二人已经不想再盯着许半生了，而是跟上了龙潜坤和秦开元。

而封之也直到许半生一曲终了才发现，自己和邹南芳竟然也在不知不觉之中随着包间里那些女人的放形骸而产生了念，只是他们并不自知，却被这一首《难念的经》彻底警醒。

也正因为他们受到了这样的影响，许半生才能在封之的忍术之下，依旧察觉到他们俩的存在。

们找到那个曾经的天才。

这也是许半生所并不知，封之学过忍术，而日本则是单纯的佛国，他们的忍术很大程度上本就依托于佛法。封之是在不经意之中受到了佛法的熏陶，追究的密一些，甚至可以认为封之是佛双修的修行者。

曾文的梦境让封之的计划完全泡汤，他只能睁睁的看着许半生离开了初见会所，去了蓝蛙，再睁睁的看着龙潜坤和秦开元现在包间里，左拥右抱好不快活。

在看到龙潜坤和秦开元几乎已经彻底沦陷在女人的攻势之下，封之很是得意。可许半生突然唱的那首《难念的经》，却一下让封之觉到了莫大的威胁。

包间里又恢复了声犬的场面，已经知自己念被勾起的封之和邹南芳，就再也抵挡不住这灯红酒绿的诱惑了，哪怕他们极力摆脱，心中却也已经留下了极为重的********的痕迹。

和龙潜坤、秦开元两人一样，在封之的脑中，同样也现了佛音梵唱，钟鼓齐鸣，而且，他所受到的这些甚至更于龙秦二人。

只可惜，他们却没能等到那个封之认为的最合适的机会，或者说，连不好的机会都已经没有了。

是以，他脑中那被藏得很的分，就被许半生的这首歌彻底的勾动。

封之和邹南芳认为他们可以凭借自己的力量摆脱，人世间的七情六，对于修行者而言简直就是笑话，他们本不认为这会对他们成为任何的阻碍。

其结果是两人凭借厚的修为行压制住了念，他们以为念全消，可却并不知这念只是被埋藏在了心的更，一旦爆发，就会惨不忍睹。

一开始的时候，封之还觉到隐隐的喜悦，龙潜坤和秦开元越是荒唐，这对于他的篡位大计就越有好。

所以，在忍术的保证前提下，封之很自信不但可以藏许半生附近而不被发现，而且还可以在对其动手之后，令其误会那是龙潜坤以及秦开元动的手。
