The reason why Cai Pinghou did this was to maintain the purity of the Cai people, and at the same time, it was extremely effective in preventing the infiltration of spies from other countries. But for those who have suffered from unjustified disasters, it is an inescapable tragedy.

Wu Ye sneaked into Shangcai City, and in a high-rise building inside the city, he observed the city that was preparing for war. Uniformly lined streets, bands of heavily armed soldiers ran back and forth through the streets, and in the distance the blacksmith shop was blazing with thick black flames, and newly produced swords were constantly being rolled out on wooden carts. This is a city that is always ready for war.

Those dense swords and bows did not make Wu Ye feel anything, but it was those busy Cai people, their expressionless faces, empty and numb eyes, unconditional obedience to orders, and the heartfelt desire for war that really alerted Wu Ye.

What a terrible country!

But what made Wu Ye feel even more chilling was that in a few days, he went back and forth to Shangcai City, Zhumacheng, Pingyu, and Xincai City, and saw the same scene, Cai Guo has become a high-speed war machine, and every Cai person has lost the right to live freely, becoming a vassal of this giant war machine, working tirelessly like an ant colony, and following Cai Guo to an unknown but certainly bloody future.

Especially in Shangcai City, Wu Ye saw four giant chariots, he had never seen such a chariot, the whole body was dark, all closed, only at the top there was a small warehouse door for people to enter and exit, no horse traction, you can start on your own, after starting, there are four thick chimneys at the back of the chariot emitting thick black smoke, roaring, under the chariot is a track wrapped in wheels, the ground is pressed out of a deep ravine by it, Wu Ye saw the depth of the ravine, it is estimated that this chariot has at least six or seven thousand catties of weight, is it all solid structure? This behemoth is almost invincible when put on the frontal battlefield, an ordinary sword is simply a joke in front of it, and the chariot doesn't care about anything, just push it flat.

Judging from the way the chariot moves, it is very similar to the chariot from overseas, it is said that this kind of podage caused a sensation after it was transmitted to the mainland, but it was soon left out in the cold, the specific reason is not clear, Wu Ye had seen Mozi's improved chariot in the Zhili Hall in Linzi, Qi State, it can directly use the hedron that has stored energy to drive, abandoning the original bulky furnace design of burning coal, smaller in size and stronger in power, but due to the scarcity of spars, this high-grade chapel can not be promoted, and can only be tried as an experimental sample. But even the most basic primordial pilot, in Wu Ye's opinion, is also very valuable for promotion. It has strong power, simple structure, and a wide range of applications, but it is not valued by all countries, and it is inexplicably drowned in the tide of history.

If this is really the case, then what are the countries that have the technology of the actuator, and to what extent has it developed now, thinking of this, Wu Ye couldn't help but add a little awe to the strength of superpowers like Qin, Jin, Qi, Chu, and Yan hidden beneath the surface.

Little Cai Guo, how could he have such a weapon?

Obviously, with the strength of Cai Guo is not to monopolize this technology, the only way to obtain this technology is that one of the five major vassal states gave it support, you must know to build a chariot of this level, the driving force is the most critical core part, but the vehicle architecture design, material selection, casting, is also essential, the material of these four chariots is excellent steel, this is the smelting technology brought by the wise man to the world, which greatly promoted the scientific and technological level of the war of the countries, and also widened the gap between the war strength of the countries.

Cai Guo can't monopolize the technology of the driver, and he can't produce this kind of high-quality section steel, so where did the four chariots come from, and who is the force behind Cai Guo?

Wu Ye sat in a hidden corner of Xincai, although there was a steady stream of Cai soldiers passing by, but this kind of cannon fodder-level Cai Bing couldn't find Wu Ye who was deliberately hidden. When the big war starts, these cannon fodder must be at the forefront and use numbers to make up for the gap in combat power.

Wu Ye really couldn't figure out why Cai Guoguo chose such a way with no way out, Cai Guoguo was overloaded, and if he didn't go to war within a year, he would be dragged down first.

If there is a war, who will Cai Guo choose as an opponent?

Cai's neighbors were Zheng, Chen, and Chu. The behemoth of Chu State, the land area is the first among all countries, compared with Cai State, it is simply the gap between ants and elephants, Cai State will not be stupid enough to stage a farce of greed and lack of snake swallowing elephants. Then the rest is Zheng Guo and Chen Guo.

Last year, Cai Guo invaded Yanling, but when Wu Ye quelled Zheng's civil strife, Cai Guo was very interested in giving up control of Yanling, judging from the current situation, Cai Guo's "knowledge" at that time seemed too interesting, and the deliberate traces were obvious, as if he intended to show that he was just fishing in troubled waters, taking advantage of the chaos and leaving, intending to let Wu Ye relax his vigilance against Cai Guo.

Wu Ye patted his head at high speed and said with a wry smile: "Time, it's really a bit tight." ”

Xinzheng, inside the royal palace.

A chamberlain hurried to the study, knelt down at the table full of official documents, and said breathlessly: "Acting king, the king is awake." ”

Zeng Jing opened the official document in front of him, saw the chamberlain in front of him, and asked, "How long have you been awake this time?" ”

The chamberlain replied: "I have been awake, and the painting saint Wu Daoxuan has returned to the palace, taking care of the king by his side, and using his energy to maintain the state of the king." ”

Zeng Jing immediately got up and ran out of the study like the wind, and the official documents full of cases were blown in the air by the wind he brought up, scattered all over the ground.

Wu Yong's situation at the moment is very strange, his blood is vigorous, full of vitality, and the whole person is so good that it is not good, but he is always sleepy, and he has been groggy since he came back from Weiguo, and the time he is awake every day is less than two quarters of an hour, Zheng Guo's doctor can't find the reason, and he is helpless. Fortunately, except for drowsiness, Wu Yong's body did not have any other abnormalities, and his thinking was very clear when he was awake, and there was no problem talking to Zeng Jing.

Wu Yong said that he felt that there were always a lot of people talking in his ears, he didn't know these people, and he didn't want to listen to their voices, but even if he covered his ears, he couldn't escape these sounds, because the sound did not come from the outside world, but from his body, from morning to night, the voices of these people have never stopped, the voices are either flat or high-pitched, there are male voices, female voices, old and young, as if Wu Yong lives in a world in his body, and the sounds of all creatures in this world are transmitted to Wu Yong at all times.
