Returning to the battle array, Hua Mulan snorted and said to herself, a fool is only going head-to-head with Xiang Yu, knowing that he is invincible, isn't that sending him to death?

Next, the Qin and Chu armies launched a series of battles.

However, Zhang Liang sat in the Qin army, no matter what tactics Fan Zeng used, sneak attacks, ambushes, bluffs, feints, camps, luring snakes out of the hole, etc., were easily resolved by Zhang Liang, and did not give the Chu army any chance.

Frontal attack, the Chu army tried to attack several times, and each time it was a loss of troops. The battle formation of the Qin army was too tight, and the Moon Tribulation Array swung up, no matter how Chu attacked, it was all bloody.

Although it was a decisive battle in the field, the Qin army brought a large number of heavy weapons and equipment such as catapults, ballistas, ballistae, and chariots. The chariots were linked together and immediately formed a powerful defensive position, followed by pikemen, archers, and shieldmen. No matter how the Chu army attacked, the defensive position was as stable as Mount Tai.

It's not that the Qin army can't defeat Chu, it's that they don't want too many casualties. Otherwise, with the 70,000 soldiers and horses in Mulan's hands and the 50,000 soldiers and horses under Han Xin, they can win no matter how they fight, the problem is that the casualties are uncontrollable. After all, Xiang Yu's personal ability is too strong.

In the decisive battle of Chu and Han in history, after Liu Bang defeated the princes, he led the princes of the world to attack Xiang Yu together, with a force of nearly one million. Han Xin alone has nearly 400,000 troops in his hands, and the other princes are also not weak.

Ye Tong subdued the princes, directly disbanded the soldiers and horses of the princes, and let the soldiers go home to farm, not included in the Qin army system, it must be weak in terms of troops, Ye Tong has been taking the route of elite soldiers, and it is impossible to raise too many soldiers and horses.

There are too many soldiers and horses, one is the high cost, and the other is the weak combat effectiveness of the soldiers and horses, no matter how many there are, it is useless. After all, the Qin Empire has entered the era of steam engines, technology will advance by leaps and bounds, and weapons and equipment will also change qualitatively.

--------------

Ye Tong led 10,000 horsemen to Yang Zhai City, and on the way, he met the plum blossom guards sent by Huang Yueying and sent Ye Tong more than ten new toys.

Ye Tong was directly dumbfounded when he saw it!

The new toy in front of him is a 60mm mortar, this toy Ye Tong just casually said the principle, and did not arrange for Huang Yueying to develop it.

Ye Tong opened the letter sent by Huang Yueying, shook his head and smiled bitterly after reading it. Let Huang Yueying develop real artillery, she is good, saying that the artillery has been developed, the problem is that it is difficult to process and the cost remains high.

Huang Yueying suddenly remembered what Ye Tong said about mortars, so she tried to develop them, and after research, she found that mortars are easy to produce and have simple technology, unlike artillery, which is too demanding and difficult to process.

In fact, mortars are the least technical weapons, with short caliber and easy to process. The same is true for artillery shells, which do not require too advanced technology.

Artillery is different, the barrel is too long, processing is difficult, and the accuracy requirements are high. At present, Dingjun Mountain is a lathe, milling machine, drilling machine, boring machine and other equipment powered by a steam engine.

However, the power of the steam engine is limited, and if you want a high-power steam engine, you have to study it or study it systematically. Only when the steam engine is powerful enough, the performance of lathes, milling machines, drilling machines, and boring machines can be improved.

Besides, when we first entered the era of the steam engine, many technologies were not perfect, and the foundation was too weak, so it could not be made up in a day or two, and we had to adapt to the arrival of the new era from the craftsmen.

Ye Tong asked the artillery to shoot a few rounds to try.

The artillery tested a few rounds, the accuracy was good, and the effective killing range was relatively short. Only between 500 meters and 600 meters, the real hit rate is within 300 meters, and the gunner can do that and that.

Ye Tong nodded, knowing that it was a gunpowder problem. It's good that black powder can have such an effect, and I hope how powerful it is.

At this moment, Sissi asked puzzledly: "Master, why don't you promote the base core car, once the base core car is promoted, you can develop a lot of technology, and you can also exchange for many excellent engineers, the price is quite cheap." ”

Shame!

100 million wealth points, at this time, Ye Tong fought the Second World War, eliminated so many Hun iron horses, the system only rewarded 20 million wealth points, recovered more than 30 counties, and only got more than 30 million wealth points, with a total of 60 million wealth points in his hands, which is enough for the base core car to be promoted!

"Sissi baby, brother has no money! There are only 60 million wealth points, and it takes 100 million wealth points to promote the core car of the base! ”

Hee-hee!

"Master, you're mistaken, hasn't the master been looking at how many wealth points are needed for the promotion of the core car of the base?"

"Sissi, look! It takes 100 million! ”

"Master, that's the original, Huang Yueying's invention of the steam engine has marked the Qin Empire's entry into the steam engine era. If the system is promoted again, the price will be greatly reduced, and only 10 million wealth points will be needed to promote the core car of the base. ”

Burst!

Ye Tong rolled his eyes directly after hearing this!

What's going on! The upgrade of the core car of the base will be forgotten, it is because I take it for granted, thinking that the price will not change, who knows that Huang Yueying invented the steam engine, the system is recognized, and the promotion conditions are greatly reduced.

If he knew that he could be promoted, Ye Tong would definitely be promoted as soon as possible, and as soon as the core car of the base was promoted, not only would the military officials under him be able to instill knowledge again, but the key was that the price of some technologies was dozens of times cheaper when they were exchanged, and the same was true for the exchange of related equipment.

"Sissi! Why don't you remind my brother? ”

Hee-hee!

"Master, Miss Ben thought you already knew, so she didn't remind you."

Shame!

What a mistake!

Ye Tong didn't even think about it, and immediately ordered a promotion.

Sissi got the order and immediately promoted to the base core car, and after more than ten minutes, the base core car was successfully promoted to become the third level, and then promoted to the fourth level, it is to enter the electrical era, I am really looking forward to it!

In Dingjun Mountain, Huang Yueying and Shangguan Wan'er in the core car of the base were talking together, when suddenly the core car of the base buzzed softly.

Next, the core vehicles of the base began to increase in height, and the related projects also increased a lot. All of a sudden, the two of them were scared.

The two ran out of the core car of the base, and after looking at it for a while, Shangguan Wan'er said, "Is it to promote the base?" ”

"Didn't you say that you need 100 million? When did the general have a billion fortune points? ”

"I don't know, wait for the general to come back and ask, and I'll understand."

A few minutes later, the promotion of the core car of the base was completed, and the two of them went in again and saw that the appearance of the core car had changed greatly, whether it was the scale, style, decoration, and project, it had undergone earth-shaking changes.

"Wan'er, take a look, there is something in the base core car that is useful to us."

Hee-hee!

"Indoctrination!"

The two of them went directly into the knowledge indoctrination room for knowledge indoctrination.

After turning over the knowledge indoctrination, Huang Yueying, who came out, opened her mouth wide, with an incredulous look. That knowledge is too mysterious for Huang Yueying!

If it is really like that, not only can its own steam locomotive be developed, but also warships with superior performance, various new materials and new processes.

It was like opening a door, and Huang Yueying's mind fell into it all of a sudden.

Shock!

Absolutely impressive!

Shangguan Wan'er did not inculcate those science knowledge, but only instilled liberal arts, which also benefited Shangguan Wan'er a lot, and her thinking was expanded. Some new methods, theories, and knowledge have made Wan'er fall into it.

Huang Yueying, who was sluggish, was shocked in her heart, it turned out that the artillery was like this, and some aspects of her research were not quite right, and it turned out that the steam engine could still be played like this; By the way, the rifle is like this, I went into a misunderstanding, wasted too much time, and was angry, why didn't I get promoted earlier.

Hum!

After instilling knowledge, Huang Yueying has changed as a person, some knowledge that she didn't know before is fully understood, and some process problems are all answered.

By the way, what kind of oil can the steam engine use, what kind of thing is that? With that oil thing, the power of the steam engine increased dramatically.

Chemical industry, materials industry, chemical industry, machinery manufacturing, electron tubes. Huang Yueying found that her mind was full of some new knowledge, and she had not fully mastered it all of a sudden, so she had to slowly sort out the knowledge in her mind and turn it all into her own knowledge before it was over.

Half an hour later, Shangguan Wan'er and Huang Yueying came back to their senses, glanced at each other, looked at each other and smiled, smiling incomparably brightly.

Shangguan Wan'er said: "Yueying, the base car has opened a door to the future for us, there are many things and phenomena, which could not be explained clearly before, but now they are all understood." ”

"Wan'er, that's right! The base car has opened the door of science for us, and Miss Ben is now looking forward to what kind of knowledge will be instilled in us when the base car is upgraded."

What Shangguan Wan'er and Huang Yueying don't know is that after the two of them instilled knowledge, their intelligence has been greatly developed, Huang Yueju is the most demonic, and his intelligence has increased from the original 112 points to 150 points, an increase of 38 points at once, which is terrifying! It's too wicked!

Shangguan Wan'er also improved, and her intelligence directly increased from the original 101 to 120 points, exceeding the limit of 110 points for a first-level civilization planet.

If Ye Tong wants to be in this city, he will be absolutely stunned and stupid!

The second girl doesn't practice the magic trick, and her intelligence improves so fast, Ye Tong cultivates the magic trick every night, and the improvement is as slow as an old ox pulling a cart, which can't be compared at all.

Hum!

Huang Yueying said: "Miss Ben will be able to complete the task assigned by the general immediately, hehe!" It's so easy! ”

If Huang Yueying knew that because she invented the steam engine to make the core car of the base successfully promoted, it is estimated that Ye Tong would soon have to exchange it for Brother Pig.

Huang Yueying's invention, just from this one, saved Ye Tong 90 million wealth points. Exchange Zhuge Liang for 70 million wealth points.

This kind of thing, Ye Tong will not say it to Huang Yueying, after saying it, there will be constant trouble, not to mention that Huang Yueying has the enthusiasm. This is Ye Tong's usual idea, squeezing the ability and potential of his subordinates.

-------------------------

Ye Tong asked the internal guard: "What about the 20,000 musketeers trained by Qi Xin?" ”

"General, the 20,000 musketeers trained by Qi Xin have already been prepared, 5,000 will be transferred to Yanmen Pass, 5,000 will be transferred to Han Xin, 5,000 will be transferred to Hua Mulan, and the remaining 5,000 will be stationed in Xianyang City. In addition, the muskets that Chen Fei and Lu Ze needed had already been escorted by 5,000 soldiers and horses, and they should be in the hands of the two of them. ”

"Let's go! Let's rush to Yangzhai City as soon as possible and join Mulan. ”

Ye Tong led 10,000 cavalry to the road again, not in a hurry, and still drove at the normal speed of the cavalry. The problem is that the soldiers are too hard, once they are too tired, they can't fight when they get to the battlefield, and in that way, it is better to march normally.
