Snake Road in particular disk array with the snake ring, that is, first came here the other maze using random, first spent a day run the whole way to understand and then use a random fly, snake ring array can also fly, so to be tied with eight random consumption mainly in the Snake Road site, snake ring that strange multi-burst, N is also more than the middle of the White Snake is a snake of five Hall, there are three White Snake Brush loafers, but there is also fierce private Qing Dynasty, the general or other练级then into the bar, the White Snake to kill more than the total return or, if it is with the Master Taoist group, then, the 33 best to find a good training or a hammer and then with the Road do not turn to anything, they may take a random healing with a row of a row of red, or Fu Road plus a bunch of people, with the two drugs package is enough, do not consume all the basic blue baby in the act, such as a hammer to go back 67 to take into account re-bills, following the easy to frequent high-level rebellion, or go back and re-recruit a good point, in short time would be to group the words that a law to go with the baby, then it is difficult to kill one would have to go back to tonic, and secondly a lot of bored people will come to steal the baby, even if you win PK drug consumption is now unavoidable, so the best fighters mixed with the Road , but here a man, if more than more than 9 in this练级individuals, then you do not intend to add on, and find it somewhere else, the least strange is the lack of Babel, against the devil, and not off-limits练级is to blame the other side of the same difficulty, but the experience is not how high.

尤其是盘蛇道跟蛇环阵，就是迷宫这里刚来的别用随机，先耗个两天跑跑路全搞清，然后才用随机飞，蛇环阵也可以飞的，所以要带八捆随机主要是耗在盘蛇道，蛇环这怪爆多，白蛇也N多中间是五蛇殿，刷白蛇还有三头蛇王，不过这里包场清人也比较凶，一般练级的话还是别进了吧，白蛇杀多了总还是有回报的，如果是法师跟道士组的话，法最好过33级找好锤子练升一级然后跟道去什么都不要背，就带随机跟一排疗伤一排红，道的符还是一捆加身上，毒带两大包足够了，蓝基本不耗都宝宝在做事，等锤子六七级时考虑回去重招，级高之后容易频繁叛变，还是回去重招好点，总之想待长时间的话一定要组道，一个法跟宝宝去的话是很难的，一来杀会就得回去补药，二来很多无聊的人会来偷宝宝，就算你PK赢了耗药是免不了的吧，所以还是战士跟道最好混了，不过这里得看人，要是超过九个人以上在这练级的话，那么你再加入就没意思了，找别的地方吧，怪最不缺的就是通天，逆魔了，不去禁地练级，是为了那边的怪一样难，但经验却不见得怎么高。

Has invested nearly billion highway completed Dayun cable, Central Rural road widening, cement every village access road circuit, the Industrial Park road network, tourist routes, such as more than 130 km road circuit construction, the realization of the "cross-border road level, and a ring of rural roads and village roads pass standardized "so that the traffic Houma advantage was further enhanced.
