"It's so strange. How can our opponents know in advance every action we take?" Li Yuanfang sighed.

"Nothing strange is because we have spies around us!" Di Renjie said lightly, as if he had been used to such things.

"Spy?" Li Yuanfang said in surprise, "We have only three people in total. Who is the spy? Could it be that Lord Di suspected that I or Brother Hu is a spy?"

"Yuan Fang, don't think too much, you really want to think about it, it will be revealed soon!" Di Renjie smiled in disbelief and reached out and patted Li Yuanfang's shoulder gently.

Lanyuan.

Zhang Lin put all the troubles behind his mind and thought about how to make achievements and get promoted quickly to kill Wang Zhiwen. If he wants to be promoted to a marquis, it is not something that can be achieved by offering a dozen buckets of candy or breaking one or two small cases. He must make great contributions.

If you can get rid of the snake spirit spies in the palace and court, it will definitely be an invincible achievement. However, most of the snake spirit spies have obtained the credit of Wu Zetian, and it is quite difficult to disagree with it, and it is difficult for Wu Zetian to believe it. Before, they were stably assassinated when they were unintentionally touched. If they were intentionally provoked, they would be subjected to their ruthless revenge and cruel killing.

Therefore, to get rid of the snake spirit, you should plan carefully and then attack thunder and make every effort in one battle to succeed, without backing yourself. If you backing yourself, you would rather not provoke them.

The time is not yet ripe, so I can only take it slowly.

Zhang Lin also thought that the Turkic mission was killed in the Great Zhou territory, and the war between the Turkic and Great Zhou was about to break out, and his opportunity to use his skills should be coming soon! He must be prepared in advance so that he can seize the opportunity, make a grand career, make a name for himself, be promoted to a marquis, and kill Wang Zhiwen.

Thinking of this, Zhang Lin was excited and locked himself in a spacious and bright room, and began to study the improved crossbow.

Although he does not have the ability to invent, as an engineering man, he still has some ability to imitate and modify. With his ability and equipment at that time, it is definitely not possible to create fine equipment, but it is still possible to modify rough crossbows.

There were crossbows at that time. What Zhang Lin had to do was add a slug and arrow groove so that he could shoot several arrows in a row and become a crossbow. This could be done by his ability.

Before modification, drawing drawings are of course indispensable, which is Zhang Lin's strength. During his days in Lanyuan, he drew extremely detailed and realistic drawings.

What he drew was not only a sketch of a hand-held crossbow, but also a pattern of a car-mounted crossbow. What he pursued was continuous firing and a longer range!

Continuous shooting represents speed, speed and range are the key to winning, and compared to speed, range is more critical!

Think about the world he traveled through before, the strength of the country depends on the range of the missile.

The range depends on tension, and tension depends on the elasticity and toughness of the string. It is best to use dragon tendons as bow strings. Of course, in reality, the dragon tendons cannot be obtained, and generally the strings are made of animal tendons. Zhang Lin considers using animal tendons and copper wire to wrap them together, which may increase toughness and increase range.

After solving the continuous firing and range, Zhang Lin began to think about carrying flames or gunpowder on the arrows to increase the destructive power of the explosion.

Destruction is a more important key than continuous firing or range. Think about how amazing the power of the atomic bomb is! Of course, it was too illusory to mention atomic bombs in ancient times. However, even ordinary flames can produce great destruction if they can be used well. There were too many examples of fire attacks in ancient wars. In Sun Tzu's Art of War, a single chapter of fire attack is obviously stronger than water power. Water can be eliminated and fire can be seized. In the wars that you may participate in in the future, fire attacks must be used in large quantities.

However, water and fire are ruthless. When fire burns the enemy, it will also burn itself. Therefore, fire attacks must be very cautious. It is very necessary to install the flame on a long-range archery cluster.

With this idea and drawing, Zhang Lin felt that he could succeed in one battle and be named a marquis for thousands of miles!

The crossbow can be made by using the equipment of Shanggong Bureau, while the crossbow on car is a large instrument and may not be made with good gold.

The idea is beautiful and the plan is extremely comprehensive, but he cannot go out of Lanyuan, to Shanggong Bureau, and to Shanjin Bureau. The beautiful plan can only be stranded on the drawings.
