Unlike Guo Zhongjun, most of the young Yuzi disciples entered the Ziyang Guannei Pharmacy and studied medicine with Xuan Yue, Xuan Ji and Xuan Tao.

At present, 29 disciples have entered the Ziyang Academy to teach, and the 16 young disciples who are solid in martial arts and hard-working jointly selected by the Daoist of the Ziyang Guanxuanzi generation have successively entered the Ziyang Martial Arts Hall to teach martial arts, learn the new martial arts brought back by Zhu Daolin from the overseas Tianshu Pavilion, and fully assist Zhu Daolin, a jade-character junjie who brought infinite hope to the Shangqing faction in Maoshan.

Guo Zhongjun quickly displayed his integrity, superb martial arts skills and steady character, and was deeply trusted and respected by Zhu Daolin, and it didn't take long for him to be promoted to the deputy chief instructor of martial arts.

The Taoist elders of the Ziyang Guan Xuanzi generation all clearly knew that Zhu Daolin's requirements for Guo Zhongjun, who was rich in experience and mature and diligent, were far higher than those for Yulong, Yulong, and Yang Dading, whose legal name was Yujian.

The ambitious Guo Zhongjun cherishes the hard-won opportunity.

During the three months he served as a teacher at the Ziyang Martial Arts Museum, Guo Zhongjun undertook heavy training tasks during the day and studied basic military theories eagerly at night, thoroughly understanding the working principles of muskets, artillery, compasses, and telescopes, and mastering the observation methods and complex calculations of sextants.

At present, Guo Zhongjun is studying the "Military Surveying, Mapping and Cartography" given to him by Zhu Daolin, and when he encounters something he doesn't understand, he can get Zhu Daolin's personal guidance.

However, Guo Zhongjun, who has always been meticulous, made a big mistake this time.

Guo Zhongjun thought that the detachment of Baoshan Port would go north to Tianjin with Zhu Daolin, so he did not bring the charts and sextants that Zhu Daolin handed over to him before leaving Jinling, who knew that the fleet did not come back when he arrived at Baoshanwei, and although the two 300-ton warships brought by Guo Zhongjun from Longtan were improved two-masted warships, the equipment was much better than the three battleships taken by Xu Hongji, the Duke of Wei, but most of the ships were recruits who had been in the army for less than two months.

Two captains over 30 years old. It was Zhu Daolin who was transferred from Xu Hongji to the water war veteran of Shangyuan Qianhu, but neither of them was illiterate, and after setting sail, Zhu Daolin ordered to take out the sea chart, so Guo Zhongjun was dumbfounded like everyone.

Although Zhu Daolin was unhappy, he did not blame Guo Zhongjun, and immediately issued an order to "sail along the coast". He instructed the captain Chen Xuan to bring a piece of white cloth, and then asked Zhao Huaizhong, the eunuch on the same ship, to take out a brush and an inkstone from the rattan box he carried, and asked the nervous signal soldier to bring the low square table hanging outside the ship building and place it on the deck.

Based on his somewhat vague memories, Zhu Daolin slowly drew the coastlines of the Yellow Sea and the Bohai Sea on the rickety boat, and then marked the coastal prefectures, ports, routes, and approximate voyage figures in detail.

The onlookers were stunned, Guo Zhongjun admired it after watching it carefully, and felt a lot less guilt in his heart.

After Zhao Huaizhong finished praising it, he pointed to the place between Lingshanwei on the coast of Shandong and Aoshanwei on the east of Jimo and asked, "Daolin, are you wrong about this place?" We remember it clearly. There is only a floating mountain front office on the seaside in the south of Laoshan Mountain, which seems to be a thousand households directly under the jurisdiction of Shandong Bingbei Road, and there is no name of Qingdao Thousand Households! ”

When everyone heard this, they all turned their heads to look at Zhu Daolin, who was sitting cross-legged.

Zhu Daolin pondered for a while, and soon understood that he was confused by preconceived ideas, Qingdao was just a small fishing port at this time, and no one in the world of the Ming Dynasty realized Qingdao's important strategic position and excellent port conditions, so he humbly accepted the opinion: "Oops." I'm afraid I was mistaken, I'm sorry...... Little Robb—"

"Here!"

The chief flag officer with a red and yellow signal flag on his waist ran quickly.

Zhu Daolin asked, "Which of our two brothers has been to Tianjin Port with the fleet?" ”

The young flag officer Luo Bowen was full of embarrassment: "Not a single one...... Almost all the veterans were transferred to the freshwater fleet. Last time, several general banners and hundreds of households who followed the fleet to deliver goods to Tianjin also went to the Nanda Camp under the Lion Rock for special training a few days ago......"

"Alas, except for the captain and the five general flags, our two ships are all newcomers who have been in the army for two months, and everyone is crazy when they hear that they went north to Tianjin. A few of us who led the troops died of sorrow. ”

Xu Wenjue and Zhang Dezhong laughed when they saw it funny, and Zhu Daolin couldn't help laughing: "It's okay, it's the first time I've taken this route, you pass on a word to the brothers on my behalf, it's the south wind and the southeast wind blowing these days." The sea is calm and smooth, as long as you take out the skills of your usual training, you can successfully arrive at Tianjin Port. ”

"When we come back, the north wind should also rise, and it will be smooth sailing...... You don't have to worry and do it! ”

"Understood!"

The young flag-chief officer walked to the aft deck with a fluttering eyebrow.

Chang Yanjun pointed to Jing Haiwei in the southeast corner of the Jiaodong Peninsula and asked curiously, "Brother, when will we arrive at this place?" ”

Zhu Daolin stood up and looked around, and found that the two warships had come to the sea area about 5 kilometers outside the mouth of the river, and under the strong south wind, the speed of the warships with full sails gradually accelerated.

He roughly estimated the mileage, and replied to the people who were deeply concerned: "The voyage from the mouth of the Yangtze River to Jinghaiwei is about 650 kilometers, and it will take four days at our current speed, but we need to sail along the coast, first to Qingdao, and then to the east to bypass this corner of the southeast of the Jiaodong Peninsula, that is, where Jinghaiwei is located, and then go north along the coast to Weihaiwei in the northeast corner, so that it is safe." ”

"Due to the strong wind near the sea, the sailing time is relatively long, and we will arrive at the Fushan front site at the foot of Laoshan Mountain in the morning after about 3 days, rest for a day and continue to hurry, and strive to reach Weihaiwei in 3 days."

"When you get to Weihaiwei, you can enter the calm Bohai Bay 150 kilometers west, and you can walk all the way to Tianjin Port, as long as you don't encounter bad weather, the whole voyage is about 13 days."

Zhao Huaizhong laughed: "Okay, as long as you can arrive at Tianjin Port smoothly in 13 days, everything will be in time." ”

Everyone is very optimistic, in order to adapt to the Yangtze River water battle and rapid patrol, the two 300-ton warships have two masts with high and low matching, and two new semi-hard sails are installed respectively, which are much faster than the 500-ton warship, and the operation is also very convenient.

If the wind is smooth, according to the mileage calculation, you can enter the Haihe River in 11 days to reach Tianjin Port, and even directly enter the canal to Tongzhou.

However, Zhu Daolin had never walked this route, and he felt that his own sailing experience was very lacking, and it was difficult to predict whether he would encounter strong winds and waves after entering the Yellow Sea.

Despite this, Zhu Daolin still didn't want to affect everyone's mood, let alone affect the morale that was still quite high. In his opinion, as long as you are cautious and do not sail far from the coast, nothing serious will happen, and if it is a big deal, you should stop moving forward, and rest for a whole day and a half before leaving.
