On Crescent Island, as Ye Tao's work gradually unfolded, Lu Dan and Liu Qing basically became secretary in charge of Ye Tao's different affairs.

After working with Ye Tao for so long, Lu Dan has become an indispensable and important figure in Ye's series of businesses. He is very clear about the progress of the things that Ye Tao has launched, and knows what aspects of work are being carried out in Tiecheng, Danyang New District and Bell Tower, Yizhan Tower, Tissot Watch House, Danyang and Yicheng workshops are doing, how much manpower and material resources are occupied, and how progress is. When Ye Tao has something to find someone to be responsible for the production, or to take on a project, he can always choose the right person who appears from the complex human resources system of Ye's workshop who has no important work and can shoulder the responsibility. Although he still doesn't understand various technical problems, this does not prevent him from becoming an excellent management talent.

On Crescent Island, before Ye Tao gave instructions, he had already integrated the apprentices, students and temporary technicians, transferred tools and equipment from the workshop headquarters in Yicheng, transported materials, and transferred some personnel to establish another branch of the Ye Family Workshop on Crescent Island. This branch gathered all veterans in the ordnance production of the Yicheng branch of the Ye Family Workshop. Although the cost may be increased, it is more conducive to the confidentiality of ordnance technology. After receiving the strong support of the Ye Family Workshop, the work efficiency of the shipyard on Crescent Island has been improved step by step.

Liu Qing is responsible for another matter. After Ye Tao arranged the planning of Crescent Island through him, Liu Qing would naturally discuss the allocation of funds and manpower with the deacons of Qihai Trading Company, and would not let these chores hinder Ye Tao's thinking. At the same time, he was also responsible for summarizing the requirements of various members of Qihai Trading Company, from the improvement of the production process of some products, the construction and design of the store, the garden planning and design, the development of new products, and so on, to small matters such as the need for furniture repair at some members' homes, he would directly discuss with Lu Dan about those things that did not bother Ye Tao. Those problems that the existing technical reserves of Ye's workshop can solve. If they are already in the promotion and application stage, they will formulate solutions with Lu Dan, and some of them are temporarily shelved due to various problems, and then report them to Ye Tao for instructions on whether to decrypt it.

Liu Qing, who is not yet familiar with Ye's Workshop, was repeatedly hit by Lu Dan in the first few days of these working places. Only then did he know how strong the technical reserves of Ye's Workshop are - at least, Ye's Workshop has never been operated at full capacity. He maintains the Ye's Workshop, which is parallel to learning and production. If necessary, the production capacity of various items can be tripled in a short period of time.

However, the efficient work of these two people did not make Ye Tao's temper improve too much. Ye Tao, who was not originally planning to stay on Crescent Island for a long time, was troubled by various affairs and could not get out.

The most important thing is the training of the crossbow gunners. After seeing the power of the crossbow guns, the two Cangshui ships traveled back and forth to Yicheng once, bringing orders for two hundred crossbow guns, and also bringing 400 soldiers who used to operate the Divine Arm Bow and the Cast Stone Car to learn to use the crossbow guns. The accuracy of the crossbow guns made Min Yue and Peng Detian extremely moved, and they were even very interested in the peculiar nature of the Mars bombs. Now, Min Yue is very busy for a year, but he still said that he would come to Crescent Island to see the crossbow guns and Mars bombs in ten days.

This kind of training is not simply to teach everyone how to throw stone bombs or turbulent bombs and Mars bombs. In this training, Ye Tao systematically taught the Qihai Trading Corps, how the Yicheng Navy and Sergeants and the Yicheng City Guards how to use a series of ranging and observation instruments developed by the Ye Family Workshop. How to calculate the shooting elements... This involves basic mathematics and physics, which is exactly what everyone lacks. However, it is not a gain. During the entire training, there were so many accurately calibrated ground crossbows and so many people who could be demolished. Ye Tao took the lead in writing a quick-tracking manual for shooting data of two types of crossbows. Although all Dongping sergeants, including Ou Zhen, understood that this manual was an absolute military secret, they could not control the spread of this manual.

Another extremely important thing is the occasional thing Assad mentioned, which reminded him of another weapon of fire attack that occupying and its important historical position - the Greek Fire. In addition to ordering ten crossbows on behalf of the Samir family, Assad was also very interested in the Mars bombs that the Qihai Trading Company could supply to the outside world. Assad had land and money, but he ordered 800 Mars bombs without considering it. You should know that in the previous battle against Ice Shark Island, only less than 300 were consumed. And Assad said half sincerely and half praise that the power of the Mars bomb could be comparable to the legendary Greek fire. It once again activated Ye Tao's imagination.

Greek fire is a liquid burning agent used by the Byzantine Empire that can burn on water. It is mainly used in naval warfare. "Greek fire" or "Roman fire" is just the name of this terrifying weapon by the Arabs. The Byzantines themselves called it "wildfire", "ocean fire", "flowing fire", "liquid flame", "artificial fire" and "preventive fire", etc. According to literature records, Greek fire has been Byzantine many times.

The empire's military victory made great contributions. Some scholars and historians believe it was one of the reasons why the Byzantine Empire lasted for thousands of years. The recipe for Greek fire has been lost and the ingredients are still a mystery. According to the Crusaders who were injured by Greek fire at that time, "Whenever the enemy attacks us with Greek fire, all they do is kneel down and pray for the salvation of God." That quote is enough to illustrate the power of Greek fire.

Little known about the recipes and methods of Greek fire. Later generations were noted because of the strict confidentiality measures of the Byzantine royal family. The development and production of Greek fires by Byzantine were carried out deep in the palace, and the Galinicos family, who were granted imperial orders and were firmly controlled by the Galinicos family. Modern chemists and historians have made the following speculations about the components of Greek fires: naphtha, saltpeter, sulfur, crude oil, quicklime, sulfur, phosphorus and saltpeter.

The components of Greek fire are heated in a large pot and then sprayed out by a siphon on the ship. It can also be loaded in pottery and thrown out by human hands, like modern grenades. The principle is to place different components of Greek fire in a pot, and when the pot is broken, the ingredients inside are mixed together, which will have the effect of a general spray Greek fire.

In Ye Tao's view, if the components of Greek fire that modern scientists speculate are relatively reliable, then the current technical conditions can actually be effectively produced and applied such terrifying weapons. Ye Tao has done some research on sulphur bombs, and his speculation is that sulphur bombs are made by oil through the original fractionation process and mixed with some other combustible materials. The reason why the Gao family can always preserve the uniqueness of sulphur bombs is certainly because the fractionation process of oil in this era is indeed considered to be a happy technology, and on the other hand, they control some oil wells that are easier to exploit. As long as there is oil in this era, as long as there is still the possibility of mining, since others can do it, Ye Tao feels that he has no reason not to do it.

Greek fire is like a modern flamethrower. The core of the launching mechanism is a pump. Low-pressure steam boilers can be used, but before rubber is found and sealing problems are solved, the pressure provided by this thing is too limited. Instead, using mechanical principles and using large cowhide airbags is relatively more reliable and safer. Although the range is likely to be less than one hundred meters, which is about three hundred feet, the range is almost enough for naval combat or city defense.

Ye Tao wrote to Tan Weixin, asking Tan Weixin to mobilize members of Jiuzhou Trading Company with huge power on the ground to find oil. It is easy to talk about these topics with Tan Weixin. He doesn't even have to explain what oil is or what its characteristics are. As an excellent economic analyst, Tan Weixin must have a good understanding of the power source and war source of this modern society. As for Qihai Trading Company, let's forget about this issue. Even if the sea merchants have the energy, they cannot let Ye Tao create a very despicable thing like an oil drilling platform.

Ye Tao doesn't have enough time every day. Each process requires detailed drawings to guide the work. When Sophie is not around and there is no one who can turn his sketch into drawings that meet the specifications, he spends most of his time every day drawing the drawings. This situation naturally makes him very angry while tired. His anger must be reflected in his mood and attitude that he cannot notice anytime and anywhere.

Lu Dan understood that once Ye Tao entered this kind of workaholic state, if he didn't arrange anything in place, he would definitely be scolded. Ye Tao would not take into account his identity as the young master of the Lu family at this time. However, Liu Qing did not have such an experience, but he suddenly realized that Ye Tao would never make any requests under normal circumstances, but it vaguely showed that Ye Tao was used to working in an extremely powerful team. The report on the project progress, the project budget estimate, the consumption, transportation and reserve of materials, the progress of partial migration from the Ye family workshop in Yicheng, and even the seventh
