The key to Sun Ji's discussion is still on Danmu and the Falling Moon Bow, a bow that can shoot at 700 paces and is comparable to a bed crossbow, with a Condor hand who can kill two birds with one stone, is a great threat to them, and they can't even give a perfect plan, more maybe, in their hearts, they still expect the other party to catch up. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Danmu may have a business trip, even if it was for Zhao Xinlai, they successfully avoided Danmu at that time, there were thousands of boats on the canal, it was really so easy to find their boat?

Seeing Sun Ji and their discussion of how to take precautions, Zhao Xin was a little depressed, or the level was not enough, if he was now a third-level card, he directly showed the falling moon bow, even if there was more money, it would be worth it, if there was only one, Sun Ji would use enough to suppress Danmu, if there were two, Sun Ji and Xue Yu were both elite marksmen, and two moonfalling bows were enough for Danmu to be completely suppressed, and there would be no ripples at all.

Embodying the moon bow is the best solution, but it's a pity that level 3 can be, level 2 may work hard, for example, find a chance to get money, use the money to rise, level 3, with the current card system to improve the ratio, maybe within a few years, don't even think, this is still a prediction in the current state, God knows what kind of order of magnitude the card system will give, if the order of magnitude increases, level 3 may take longer.

Zhao Xin ventured into Nanle, more to light up military equipment, in terms of increasing strength, ordinary cards are just a number of accumulation, before the upgrade, he is a quantitative change, no qualitative change, only military equipment can, in Zhao Xin's view, military equipment is only a part of the strength, when there is no way to light up the level 2 card, the role that military equipment can play is not big, what can really play a role is actually the second and third level cards, a moon bow, It already made the people with the imperial equipment a little jealous, in Sun Ji's words, Danmu is a bow and arrow, very powerful, and the others are not.

Sometimes, if you are not afraid of comprehensiveness, you are afraid of specialization, just like the special forces of later generations, they may be each or two, not as good as specialized fighting masters, or marksmanship masters, but the strength gathered together is quite powerful. The current Danmu is like this, a long-range archer, using a level 3 moon bow, the combination of the two, to get the effect of one plus one greater than two, maybe a one-on-one duel, or a small-scale duel, Sun Ji will not be afraid, but with Zhao Xin, under the mouse taboo, they can not do much, once Danmu contains the strongest masters, the rest are really a rabble, what are they going to do?

The existing weapons, not to mention level 1, even level 2 can't solve many problems, under the premise of not being able to show the level 3 moon bow, if you have time, get out a batch of level 2 strong bows, and then make changes, some designs of eccentric wheels and labor-saving devices, these basic concepts are known, it is still feasible to try it, this is not something that can be done now, what is needed is a fixed base, and there must be a set of experimental facilities to continue.

Just accept fate, this has never been Zhao Xin's doing, to be able to go from an orphan in a poor mountain village to a student of Peking University, this is not just talent, no persistent efforts, no 20 years of study, it is impossible to do this step, you know, it is a poor mountain village, not Beijing, not Shanghai, the admission ratio is amazing, at least to do the top 100 in the province, it is possible to be admitted, Zhao Xin at that time, not the provincial champion, but also the second in the city, the province's 25th results, Admitted to Peking University, under the premise of nearly one million candidates in the entire province, entering the top 30 is not as simple as one in a hundred, and there are many in a million.

If you change to the Song Dynasty, without the premise of a suitable weapon, you can only choose to escape, let Sun Ji escape here with him, with Sun Ji's strength, plus if there is a horse, there must be no problem to get out of track, the goal of the ship is huge, and there is a direction, there is a purpose, as long as you don't get off the boat, invest a certain amount of manpower and material resources, there are some difficulties, but it is not impossible, but two people and three horses, not only the goal is much smaller, but the speed is also several times faster, this is the best solution at present.

In fact, Wang Song also proposed, but Sun Ji was still hesitating, taking Zhao Xin to move forward alone, there was a great possibility of being missed, and there was a huge chance to escape, but the fault tolerance rate was even lower, and under the premise that he was alone, he could not completely solve the problem of security, once he fell into the encirclement of the other party, there was no room for resistance.

The discussion next to it has been completely messed up, after listening for a while, and there is nothing to gain, Zhao Xin will no longer listen, Wang Song They can't give a suitable solution in a short time, then they can only start from the card system, compared to a super weapon like the Falling Moon Bow, Zhao Xin can't show it, but some basic raw materials are still okay, the first thing he thought of was gunpowder.

In the county, there are fireworks and firecrackers shops, there are also gunpowder, from the middle also lit up belongs to the four major invention cards of gunpowder, these gunpowder impurities are too much, used to make firecrackers, you can, but you can't do weapons, in the 21st century, the consultation is developed, the ratio of black powder is already rotten street, on the ship, it is still not the best way, it needs to be steamed, calcined, which requires a lot of space, and the movement is too big.

Black powder is not good, Zhao Xin was not much disappointed, weapons of mass destruction, and not only gunpowder, considering the convenience and lethality, there is only chemical agents, in fact, there is one of the easiest weapons of mass destruction in later generations, Molotov cocktail, it's just that the two raw materials gasoline and sugar, are not available to Zhao Xin at present, but chemical agents are more convenient.

Chemistry is a very dangerous science, in the field of studying chemistry, countless sages have used their lives to complete the study of one or more concentrated chemicals, many chemical agents have great dangers, especially strong acids and alkalis, which seem to be just colorless and transparent, the same thing as water, but it is extremely terrible to use, which is probably the easiest weapon to obtain.

Zhao Xin carefully recalled today's harvest, after having miscanthus salt, it is not a difficult thing to make a strong alkali, compared to alkali, the acid seems to be stronger, and it is better to synthesize. Acid, it seems that in ancient China, there existed, which is also the basic material of three acids and two alkalis, the easiest to obtain, is sulfuric acid, which is also the foundation of all acids and alkalis, the starting point of chemical ability, knowing, sulfuric acid can be used as a raw material for other acids and alkalis, and the owner has a huge role.

Zhao Xin recalled carefully, he was not sure if he had seen it in it, but he seemed to have seen this kind of thing in the pharmacy, with alum, there was sulfuric acid, which was an ancient method of refining sulfuric acid, and the green alum oil finally obtained by calcining the alum was the earliest dilute sulfuric acid.

Green alum seems to be a kind of medicinal material, Zhao Xin naturally went to the Chinese medicine store, where there are hundreds of different minerals lit up, especially dozens of inorganic salt minerals, in the middle found miscanthus nitrate and realgar, this is already a big discovery, now may be able to find green alum from the middle, this in ancient times, should be more common, sure enough, in the medicine, found green alum.

Zhao Xin is about to embody the green alum, although it is not too convenient to make green alum oil from the green alum, but it is much smaller than the movement of gunpowder, just cook and condense, Zhao Xin just needs a little bit, used to light up the card, if there is alum, at most an hour or two, before he can manifest it, in the introduction behind the card, there is a related card above, which is lit, this associated card is not anything else, it is actually green alum oil (dilute sulfuric acid).

I don't know when, the alum oil has been lit, this is a great thing, on the ship, it is not difficult to get a set of cooking equipment, there are iron pots and stoves for cooking on the ship, but to condense the device, it is a little difficult, maybe, he has to show a large number of them, the crisis is in front, some can not take care of it, now it is saved.

Such a discovery, so that Zhao Xin was very surprised, carefully searched, and look at the ins and outs, sure enough, in a grocery store, I saw alum oil, this is a cleaning agent, used to clean some stains that are difficult to clean off, or copper cleaning, this is the use of dilute sulfuric acid as an oxidant and solvent, Zhao Xin is not a chemist, but he can be regarded as having common sense, alum oil is ancient sulfuric acid, which is obtained by calcining green alum and steam condensation, which is a good thing, with this, there is hope for weapons.
