There's something wrong with this guy

Chapter 109
Yu Yazi said, "Of course I can allow you to follow me to make high-burning smoke bombs, but you should learn to restrain your desire to explore, focus on a certain field, and think about more when you have achievements."

"Teached."

In the end, Xi Huanyan did not go with Yu Yazi, she went back to the stone room of the Feidu University scholar, and immersed herself in the classics and letters.

After the thunder cannon had been charged and tested, it was confirmed that there was no problem. Yuyazi notified Nanzhang, and Nanzhang sent it to Hongding Mountain.

The imperial army fired a cannon towards Baizhou, but unfortunately the opponent had an eight-star origin master sitting in the town, the power of this artillery was greatly reduced, but the opponent did not dare to act rashly.

Xi Huanyan did not witness this battle with her own eyes. She only heard Nan Zhang and Yu Yazi later describe that when the artillery shells and thunderbolts attacked Baizhou, the opponent's eight-star origin master stepped forward to intercept them. According to the earth master's judgment, the eight-star origin master had Suffering from internal injuries, it is impossible to determine the severity, so the imperial army adopted conservative tactics and did not send troops, and the two sides fell silent again.

On the other side, Xingjin beheaded the president of the Pyrothorn guild and regained Muzhou. Some guild members fled to Fuzhou and Guzhou, and harassed the border of Muzhou with the garrisons of the two states from time to time, and started guerrilla warfare. The garrison cannot shake the result of the war for the time being, but it is annoying.

If the soldiers brought by Xingjin go to guard the cities, they will disperse their forces. If they don't arrange manpower to defend the cities, they will be attacked and seized by the garrisons of the two states, so a new round of recruitment began in Muzhou and Tongzhou.

After half a month, the third No. [-] Thunder Cannon arrived in Muzhou, and the situation stabilized.

The front line was basically victorious, and there were no major turmoil in the day. Xi Huanyan found some spiritual spells that were still under construction from the letters of Feidu University, and felt that she could give it a try, so she reported to Feidu. Feidu was busy building a branch , temporarily neglecting academics, let her decide by herself.

The key words Xi Huanyan set for herself are spirituality, soul, brain, consciousness, weapons, and city defense, so her research and development direction is biased towards these.

Her first research topic is the application of vision and spiritual thoughts in equipment. She wants to reflect the farsightedness of the spiritual minder on the equipment and make an auxiliary tool suitable for tracking, which can also be said to be a telescope. upgrade.

Telescopes appeared more than ten years ago, using the light refraction principle of lenses. At first, they were folk gadgets. Martial arts masters and Genshi had good hearing and eyesight. The distance I saw was getting farther and farther, and finally attracted the attention of the government.

The empire was imposed severe military and cultural sanctions by the Western Regions, unable to obtain new weapons and learn new technologies, suddenly discovered the strategic role of the telescope, and quickly classified it as a military secret, prohibiting private sales.

But just like Ronghua tried his best to open up channels to buy the Western Region Yuanli car, Qian Baoling, Dongshi lottery, etc., the Western Region also pays attention to Ronghua's dynamics all the time. It is not difficult for them to get a telescope, and they may have learned how to make it. Yes, this time in the battle with the Pyrothorn Guild, a telescope was erected on the other side's city wall, and Ronghua's military advantage brought by the telescope was gradually losing.

Having said that, the secrets are also graded, and the top secret will be shared with the secret cabinets of the state capitals and the duke's mansion.

For this reason, Xi Huanyan applied to the Tongzhou Secret Archives Pavilion in the name of Gu Shen for access to the production materials of the telescope.

Reporting Dongjun's name may not be accepted by the Secret File Pavilion, but Gu Shen has been listed as one of Bingshan Scholars, and has certain access rights according to his position.

While waiting for the application to be approved by the Secret File Pavilion, she did not relax her research on the technique of "vision". The conceived technique of the Feidu Grand Master is called Mirage, and the first level of the technique has been fabricated.

Xi Huanyan practiced according to the manuscript, and soon mastered the method of casting the first layer of the mirage.

The mirage is endowed with the function of perspective hyperopia. The predetermined hyperopia distance of the first layer is twice the distance of the caster's own spiritual hyperopia. It can see through ordinary obstacles. She tried it, and it is true.

According to the idea written by Feidu, the distance on the second floor should be expanded to four times, and the perspective needs to be strengthened. It is best to be able to see through obstacles that have been casted or made of special materials.

On the third level, while improving the first two, it is necessary to construct an additional ability of directional investigation.

The calculations involved here are too complicated, and the Grand Master Feidu has stopped at the second level of magical formulas for the time being.

Xi Huanyan took the lead in picking this out from among the many ideas of the technique because she felt that the principle of this technique is similar to the imaging principle of the telescope, and the fusion rate may be high. If the telescope can be improved, it may be able to help soldiers defend the city.

After reading the materials for making telescopes sent by the Secret Pavilion, she set off for the astronomical observatory at the top of the West Peak of the Fenghe Mountains.

The astronomical observatory should have an astrologer who is good at astrology on duty. Unfortunately, Tongzhou has a poor foundation and has not invited an astrologer. This institution is temporarily useless. However, there is a very large telescope with a diameter of more than three meters, which can observe the stars in the sky.

Generally, the imaging of high-power telescopes is inverted, and the field of view is limited, so they can only observe parts. The field of view of the starry sky is wide, and it looks like a point. To consider external environmental factors such as weather, light, and air, it is necessary to install a erecting mirror.

The big guy in front of her can't hold it in her arms. It has the function of observing the landscape, but it has the common problem of a high-powered telescope. It is fixed and hard to move, and the imaging range is limited. In particular, the confusion array is set up near Fenghe, which affects the surrounding force field. , You can't see far away with it.

But it doesn't matter, she mainly wants to experience the mirror system and parts quality inside it.

According to records, this type of telescope can clearly see the landscape 45 kilometers away under good external conditions.

The initial hyperopia distance of the divine sense is similar to that of the human eye, but the divine sense has more perceptions such as "touch" and "smell".

The visual range of the human eye is affected by the field of vision and light. In a place with a wide field of vision and sufficient light, you can see far away. Otherwise, you can only see nearby things clearly. Spiritual thoughts are not affected by the field of vision and light. In the initial state, The farthest distance it can perceive is generally the distance that people can see when standing on open flat ground, but it will be disturbed by various invisible energies, if the surrounding force field is abnormal, it will not be able to pass through.

When she first discovered her divine sense, her perception distance was six kilometers. After she practiced it, it reached eighty-nine kilometers. After practicing the mirage, it was only twenty kilometers. Looking at it this way, the viewing distance of this telescope is very impressive.

If it is based on it, what she needs to do is to separate out the perspective technique in the mirage and combine it with its mirror system, regardless of the distance.

However, looking at the cost of the materials on the back of the file, Xi Huanyan found sadly that she couldn't afford it. Such a high-powered telescope with a spectacular landscape cost tens of millions of gold?
It's impossible for her to succeed once. If she comes dozens of times, Tongzhou may be bankrupted by her.

Taking a chance, she wandered to Jifu, which is in charge of finance, taxation and population cadastre, and made an appointment with the chief bookkeeper, Cao.

This book Cao Yeshi, when she heard her mentioning the experimental funds, her face suddenly tightened, and then she heard that tens of millions of gold would be used for an experiment that was impossible to succeed once, and she immediately cried, "It's not that I don't approve Dongjun, Curry really There is no money, people’s livelihood needs money, recruiting soldiers requires money, raising soldiers requires money, buying food requires money, making weapons requires money, follow-up rewards require money, reorganization of Muzhou requires money, and the books are about to go into the red. A few days ago, Grand Scholar Feidu took a sum of money from me, it was too difficult for me."

Xi Huanyan also wanted to cry, she really felt that she had lost her dream (╥╯^╰╥).

"I know, I know." Xi Huanyan pulled the sleeve out of his hand, "I just asked."

Book Cao wiped away his tears, and said with a shy face, "Dongjun, you are not in a hurry for this experiment, you can take it slowly, and wait until the treasury is full. You see that you have a lot of monthly cases, do you want to donate some?"

"." Are all the officials so willing to show shame now?

　The principles of various techniques in this article are fictitious, and those that involve reality are also very simple. We can only try to make sure that they do not mislead people. Don’t do textual research. Just forget it after reading it.
