Positions out of a fat man: going on now in the past, the Imperial Army came after eating is bad. Old Kings Head Rush thanked the captain
14、rushed to the base for Hong Kong, Shen Yuezhen said: I think so well! Aboard the ship, told through again. Months Pro happy meals freshly prepared, Scull chunks post immediately. Card that Fu sheng of the Elves take care of: old Kings Head tomorrow, your fish such as we Captain! Know this is the Kin
15、gs voice, by far. At night, the ship to port, next to see a few xieye of small fishing vessels, stop eating. Alex after eating two adjacent boats stopping by. Learned from the mouths of local fishermen here have is guerrilla zones, East Taihu Lake infested with bandits, Miaogang landmark, quiet at n
16、ight, sometimes in the morning zhenze Japan Devils sweep, afternoon zhenze, West of guerrilla activities. Back on the boat, monthly Pro action decided by the first programme, go to Miaogang, find focal point connector. Gently open the ship, sailed into the trackless Yang. Months Pro has lost its way
17、, dont know direction, and had to let the old King was driving. Old King pulling two oars said: good day to see the stars, cloudy day by feel. You take a break, go to class in a 构词成分。. No, the cabin there was grunting . Shout . snore. The next morning, Miaogang the Lion Bridge a mourning fishermans
18、woman. Head wrapped in white cloth, foot-wear white shoes, selling fish in a fish line. Her a red flower on the toe in his left foot, a white flower on the toe of his right foot, which is a joint sign. Women were observed on the street that a tobacco stores, posted a lot of smoke on the door, there
19、is no old knife brand. Shopkeepers facing West, there are another two strangers looking around. Months Pro knows this focal point has been exposed, she quickly sold the fish back to the Lake, get on Board of the old King said:is Shen Yuezhen, xiaozhengxin them. A few days ago, Shen Yuezhen listen to
20、 Jones Lang LaSalle said his family had firearms, ammunition, Ding Bingcheng newly established Jiangsu Taihu Lake is in need of volunteers for the war guns and ammunition, will mobilize he offered his gun out. This small secondary progressive, PWC. Today, he leads Shen Yuezhen in backyard behind a r

She returned to her own house Dai Jia Wan, think of importation of firearms program, is afraid of diwei check months Pro frown.
23、 The next day, she came to the fishermens uncle Wangs boat, said importation of firearms, Wang not only down, but also a good idea, brows that make the month pro stretch . Bei Ma Yang, ship and base for Hong Kong, the Sun has been the West, the monthly Pro will kill fish, wash, place a oil sauce, co

Wang mentioned fish basket selling on minglilai, after the Elves when the sentry, Wang carried out from the basket of three good Mandarin fish, said with a smile: Mister lucky, MA Yang, this is net live fish, Fu shengs brother to try it. The elves call
25、ed Fu sheng came holding a fish said: old Kings Head, today luck was not bad! Thanks to the blessing of day, only a little fish. Brothers, let me of the Ming dynasty to the North of the road Yang swings to get some fish? No, Ah, Eastern foreigner to prohibit! and I am not the first, not to master. That is a shame
