1.2) Chinese
Iron Weapons and Armors:
Chinese must has already employed iron weapons and even steel weapons as their conventional weapons if they were to face the army of Alex. Iron had already been widely used in the agricultural sector and was produced industrially during the Spring and Autumn era. By the time of early Warring States Period, iron casting has been widely used according to the archeological discoveries at Jiang Su Liu He Province. The Chinese of the Warring States had also developed the quench-hardened steel.
Percentage 1: Chinese would employ majority of their army with steel. – 5% (Maybe yes for the general and officers, but mass production of steel for military purpose was still impossible at that time).
Percentage 2: Iron weaponry and armors are employed widely among the Chinese army.—75%( Bronze weapon still have its place in Chinese arsenal especially during the warring states period whereby the development of bronze technology is at the apex)

Conclusion:
By all means, this would be a battle between Bronzemen and Mixmen.
Long-ranged Weapons:

Besides catapults, crossbowmen and bowmen were the standard long-ranged units in every decisive combat during warring state period. However, most westerners often underestimated the technologies and firepower of Chinese long-ranged weapons. This is mostly due to the deficient of English sources regarding this topic. Therefore, I had made references to several Chinese websites which have more detailed and pertinent descriptions regarding these lethal weapons.
Crossbow:
There are varieties of types of crossbows used in Chinese army, differences exist between nations. Crossbow has a slower firing rate compared to ordinary bow, but in turn it has greater damage and range depends on size and weight of crossbow, a heavy-weight Chinese crossbow actually shoot out spears instead of bolts.
During Warring State Period, Most of the crossbows were made with bronze. There are three parts that constitute a Chinese crossbow, Bi (Body), Xuan(String), and Wang Shan (aimer). Chinese crossbow has a greater accuracy compared to bow due to the specialized aimer Wang Shan 望山and the separated movement of string stretching and aiming. A even larger crossbow would require a basement frame(弩床

.
In general, there are three types of Crossbow during warring states according to their string stretching :
(a) Bi Zhang Nu(臂张弩

:literally arm-stretched crossbow. It was the earliest type of Chinese crossbow, shorter range but easier to maneuver. The earliest account of this type of crossbow mechanism was “Sun Bin’s Art of War”( Not Sun Tzu, it was written by a great Qi’s strategist named Sun Bin who lived at the midst of Warring State Period and died at 316 BC), with a shooting range of 100 “Bu”(步

or about 138.6 meter.
(b) Jue Zhang Nu(蹶张弩

: literally stamp-stretched crossbow. The crossbowmen employing this weapon use leg to stretch out the string instead of arm, in order to overcome the heavy resistance force of the bow. But once it shoots out the bolt, it has been proved to be a terrifying weapon. The Jue Zhang crossbow of Han faction has an effective range of 600 “Bu” or around 800 meter.
(c) Repeating Crossbow: Chinese had many inventions, and Chokonu is inevitably the most favorite Chinese military invention among many video games( AOE, CIV 4 etc) besides gunpowder and rocket. However, I have to make it clear that Chokonu was just an alternative to Chinese arsenal, and it actually wasn’t mentioned much in most of the Chinese ancient text. The reason that Chokonu has this special position may be due to its uniqueness and it was the only ancient chinese weaponry that didn’t imported to and hasn’t been exploited by the western and Arab. Basically Chokonu is a Bi Zhang Nu, it has to sacrifice the accuracy( with the aimer or Wang Shan being replaced by the bolts box) and firepower in order to get a faster shooting rate. Therefore it is only suitable to counter a large mass of army in close-ranged battle.
Bow:
The first Chinese Composite Bow was the Qin Bow and Chu Bow dated from Spring and Autumn Period, they are built using bamboo and horn. Although it has a lower accuracy and damage than the mechanical crossbow, its flexibility and maneuverability grant it a greater strategic value than the cumbersome crossbow. Inevitably, composite bow was still the main long-ranged weapons of Chinese army due to its simplicity and mass production.
Percentage 1

ercentage of Cho-Ko-Nu being employed in the first encounter.—60-80%.
Percentage 2: Percentage of mechanical crossbow to percentage of composite bowmen in Chinese long ranged units.—30%:40%
Conclusion: Enjoy the rain fall!
Firearms:
Yup, not gunpowder, but the usage of fire as a tactic to repel enemy. “Sun Tzu Art of War” used a whole chapter to depict the strategy of using fire weapon. As early as the Spring and Autumn Period, Saltpeter and sulfur has been widely known by the Chinese, along with oil and rosin, they were used to make the flaming arrows or flaming ball which would be thrown by a catapult, causing devastating effect.
Percentage 1: Firearms employed by Chinese army—30% depending on the strategy
Percentage 2: Alex’s soldiers have magical resistance to fire damage—0%.
Conclusion: After the shower, it’s time to have a sauna.
Poison:
Poison has been another strategic weapon to be used in Chinese army. They mostly used Aconitum as the source of their poison. The poison is then applied to the arrow head, even a single scratch from the arrow would cause the enemy to die within minutes. Besides, as early as 400 BC , poison gas had been used to counterattack the enemy trying to sneak into a city using underground tunnel.
Percentage 1: The first barrage of Chinese archers and crossbowmen are poisoned.—5%(There is no evidence that poison arrows have been adopted as the main weaponry during warring state period albeit the widely usage of poison as tool of assassination)
Percentage 2: Alex is invited to a Chinese banquet and is poisoned to death.—5%( ridiculous but not impossible)
Conclusion: Poison was the most humane execution in ancient world.
