After three or four circles in a row on this grassland, Zhou Ran tightened the reins and made them stop, and after stopping, Zhou Ran unloaded a large bag from the back of the main board of the chariot, which was full of beans and sour fruits, he went to put this bag in front of the two bighorn birds, and then patted their heads and let them eat as they pleased.

And he himself began to move his body, the chariot was only driven for a short while, but for Zhou Ran was very tired, in addition to controlling the two bighorn birds, trying to communicate with them, but also to feel other problems on the chariot, and consider how to solve these problems, for Zhou Ran is a two-way labor of physical and mental power.

Not to mention anything else, it seems that the main body of the chariot is still a little smaller, and now it can barely stand three people, and then it can't put any supplies, but only two of these three people can attack, and one of them must drive the reins wholeheartedly. ’

This is a problem that Zhou Ran didn't expect at first, he originally thought that the one who drove the reins could at least have a little bit of mind to attack the surroundings and the like, but the wildness of the two bighorn birds was very serious, and when they ran, they were a little careless, thinking that the stone spearmen who were driving the rope and were responsible for controlling the movement of the chariot had to pay full attention.

And the remaining two warriors are simply not enough to attack, and the two warriors are guarding one side by one, and at the same time dividing their minds and paying attention to the front and back, they have already spent too much energy.

The two main abilities of the chariot, in addition to charging, the other ability is strong mobility, which not only means that they can quickly enter the battlefield, but also means that they can quickly leave the battlefield.

Therefore, it is best to equip the chariot with 1~2 warriors with long-range attack power, and the production method of the bow and arrow is not difficult for Zhou Ran now, he has not made it, just because the material of the bowstring is not so easy to choose.

If he was willing to spend some effort, he could easily make a dozen or even dozens of barren wooden bows when all the two skills of carpentry and handicraft were up to standard, but Zhou Ran had not yet decided whether to use bows and arrows or throw stones.

You must know that the slinger can be evaluated as one of the three top classes in the primordial era, but there is a reason for him, and the class of the stone spearman can only be regarded as a strong class in the primordial era, and it cannot be rated as a top class at all.

Slingers don't have any extra abilities or special talents, but they can be rated on the same level as totem warriors, mainly because of their ability to fight at range.

Not only are stones easy to find, but they can also be exchanged for other types of weapons when throwing stones, which is much more convenient to use than bows and arrows, and even in a sense, the attack strength that throwing stones can exert is stronger than the bows and arrows of these primitive elites.

This matter is put aside for the time being, anyway, the main board of the chariot has not yet been expanded, so it is still too far to think about the problem of bows and arrows and stone throws.

There is another reason why Zhou Ran didn't make bows and arrows, that is, because he doesn't have a troop class illustrated book for archers and arrows now, and if he wants to let primitive people or stone spearmen train and master weapons like bows and arrows, it will take more than a dozen cycles to say the least, and he doesn't have so much time to waste.

In addition to the expansion of the main board, another problem is the fence, there are too many bone spurs and wooden spurs in that circle, which is indeed a good means of defense, but in the process of moving just now, Zhou Ran subconsciously reached out to grab the guardrail several times, and almost poked his hand out, after thinking about it carefully, he decided to add a few handrails to the top of the guardrail, or simply remove the defense measures of the upper circle.

As for the last problem is the balance of the chariot, when it comes to this problem, it is mainly related to the bearing structure between the chariot tires and the main board, which are all hand-made by Zhou Ran, and there is no way to compare with the equipment made by the machine assembly line.

His handicraft skills are only mastery, and he can't make 100 precision parts in a row, and he also ensures that the specifications between each part are exactly the same.

Raising his hand and patting the chariot, Zhou Ran fell into contemplation, it seems that it is really not wrong to name this chariot a trial version, for a while this chariot will definitely not be able to be put into practical use, at least it will take a month to strengthen and study.

Stretched out his hand and patted the two bighorn birds, the two bighorn birds were also tired in the run just now, and after a few laps of running, Zhou Ran also found the problem of the bighorn birds.

Their controllability is quite strong, which has little to do with Zhou Ran's wildlife affinity, he just shook the reins a few times, when the speed of these bighorn birds is not right, or the meaning of comprehension, he will tighten it a little, just a few attempts, these bighorn birds all understand, so in terms of control.

But in terms of endurance, it is not good, their speed is indeed not slow, even if they are dragged on such a chariot, the speed of running with full force can basically reach 60 miles, but the endurance is more than a star and a half, compared to the cheetah and the like, it must be a lot stronger, but they are only a short run for more than 20 minutes, and their physical consumption is very serious.

At this time, the two bighorned birds who were eating this thing were still trembling slightly in their legs, but Zhou Ran also knew that endurance or physical strength could be trained.

After all, the death game is a semi-digital thing, and these semi-digital things not only refer to players and NPCs, but also include these wild animals, who can also improve their basic attributes and abilities through later training, food and even equipment.

After the two bighorned birds rested for a while, Zhou Ran turned over and sat on the chariot again, and after coming up, he remembered that in addition to the main body of the chariot to be expanded, the weapons and equipment carried also need to be strengthened, and some additional facilities can be erected behind the chariot, and the length of these bronze spears produced must also be lengthened.

But the main body used in these spears, the hardness of the wood itself is not very sufficient, so he has to replace it with ironwood, otherwise if he blindly lengthens the length, it will not only increase the weight and is likely to make the main body fragile, but also break directly from the middle after a few battles, but if it is replaced with ironwood, there should be no problem in this regard, after all, the hardness of ironwood can be compared to metal.
