The load and distance of the command line are between the combat department and the reconnaissance department, and the road conditions are also the best. After all, being a commander does not require the best physical fitness and the ability to survive alone in the wilderness, but it will test their observation ability, and in the state of rapid marching, they can keenly observe the terrain and landforms on the road they are traveling, and make judgments about whether they are suitable for battle.

With the passage of time, the gap between the people is slowly reflected, and some candidates with better physical fitness and family history are gradually running ahead. Although Zhang Tianqi can still keep up, he is not in a leading position.

After running for another hour, Zhang Tianqi's breathing became heavier, although this slowly rising terrain does not seem obvious, but the uphill journey will consume more physical energy. I was in a hurry, and I unconsciously used the "Yijin Jing" exercises that I had been practicing hard for more than ten days. After a week of exercise, I only felt that my mind was much clearer, my breathing was no longer heavy, and my pace was much faster.

I was happy in my heart, and continued to run the "Yijin Sutra", and after a few weeks, although it still had an effect, it was not as obvious as it was at the beginning. While running the exercises, I continued to speed up my pace and rushed forward, thinking about countermeasures in my heart. Suddenly, my heart moved, and I remembered that my grandfather often reminded him that only when his body reached its limit could it be easier to improve himself. With an idea, Zhang Tianqi immediately took action to increase his speed to the fastest, ran all the way to squeeze his limit as much as possible, and gave full play to his potential. Until you can no longer run, you can run the exercises, and then continue to run wildly, and so on, gradually leaving most of the people behind.

On the other side, Liu Yu was still working hard for his 20,000 catties of bronze ingots. The cart was too small to hold much ore at all, and the Bokan Military Academy covered a wide area, and it was a long distance from the small courtyard to the warehouse, and most of the time was wasted on the way back and forth. Thinking about it, this is not a solution, I am afraid that when the assessment is over, the freshmen will not be able to smelt the 20,000 catties of copper ingots. I've got to figure out a way.

What should I do? Liu Yu pondered bitterly. It is impossible for ore and firewood to come over automatically, and I have to take care of the smelting furnace alone, and I can't wait to split myself into several pieces. Look at the small iron ring on the tail finger of the left hand, it's a pity that your space is too small, so the little space is not much bigger than the car, and it doesn't play a big role at all.

I had no choice but to borrow the power from the cave. You can't waste your time on this pointless transport, right? It's still early in the morning, and there's no one around the warehouse. Liu Yu vigilantly circled around, then walked into the warehouse and came to the place where the ore and firewood were stored. Then he took out an object from the small iron ring carried by the tail finger of his left hand, pressed it a few times, and then swept it at the ore and firewood with this thing, and a magical scene appeared, and all the ore and firewood piled up in the warehouse disappeared. Looking at the empty warehouse with satisfaction, Liu Yu put the thing that could make the item disappear back into the iron ring, and then left the warehouse and returned to the small courtyard.

Seeing that the open space in front of the yard was already full of ore and firewood that had disappeared from the warehouse, Liu Yu returned to the yard and took out the trolley, and began to transport the ore into the smelting furnace one by one, and began his smelting journey.

After entering the jungle, the speed of the reconnaissance department that set out from the West City Gate dropped significantly. Each of them had a map in their hand indicating where each person should go. In the jungle, tall trees and shrubs block the sun, and the poisonous insects and beasts that infest the jungle, as well as the examiner who is responsible for creating obstacles, all test these candidates. Most of the candidates were working hard to move forward, clearing the bushes and weeds that stood in front of them with the daggers they were given, and opening up the way forward.

I saw a person, behind everyone, slowly moving forward. I didn't see how fast he moved, so he passed through the bushes and weeds, bypassed the giant trees, and followed behind the candidates unhurriedly. While still muttering, "One, two, three, four・・・・・・"

The command candidates who set off from the East City Gate were advancing at full speed towards their destination, Kanha City, while carefully observing everything along the way, not letting go of any suspicious places. In the group at the front of the line, there was a candidate who kept gesturing as he went, and from time to time he left the road, climbed the nearby hills, checked the pond and river, went to the village to chat with the villagers for a while, and then got back on the road. He wasn't very strong, but he often didn't do his job properly and didn't see him left behind, and he still ran at the front of the line.

Zhang Tianqi was still running at a rapid pace, and when his physical strength reached the limit, he would practice the exercises. Now his running speed is gradually getting faster, and the operation of the exercises is becoming more and more proficient, and the running time is also getting shorter. I feel that my breathing has become much longer than before, my physical strength is more abundant, and the distance I run with all my strength is much longer. It went on like this for more than two hours, and it was not far from Canno City.

Zhang Tianqi also gradually rushed to the front of the team, and there were more candidates, in order not to attract attention, Zhang Tianqi also slowed down and ran forward with everyone. After repeated cultivation along the way, Zhang Tianqi's understanding of the exercises has deepened. While running towards this Kanno City, he ran the "Yi Jin Jing" exercises, reducing the fatigue on his body.

Liu Yu's first furnace of copper ingots has been refined, because he is not very familiar with the condition of the smelting furnace, the heat has not been mastered, and only about 200 catties of qualified copper ingots have been refined in two hours. Liu Yu felt that his results were not very ideal, and his speed was much slower than when he was in the mountains. At this rate, it would take nearly twenty days to refine 20,000 catties of copper ingots. What is the problem? Liu Yu was thinking bitterly.

To refine copper ingots from ore, the ore must first be melted, and after melting, it must be heated to remove the impurities contained in the ore, and when the impurities are removed, pure copper ingots can be solidified. The melting point of copper is 1083 degrees, and a higher temperature is required to remove impurities. Looking at the gradually darkening furnace fire in the smelting furnace, Liu Yu suddenly remembered that the temperature of the furnace fire was not enough, and when the firewood was burning, the air circulation was not enough, and the heat generated was too small, and the heating speed became much slower.

Thinking back to his experience in the mountains, this smelting furnace was still lacking a blast equipment. Yes, the fire is not fierce enough, how can it not delay time! Thinking of this, Liu Yu decided to solve this problem first. Seeing that it was almost noon, Liu Yu inquired about Liang Yu's residence. went straight to Liang Yu, hoping to provide him with a set of wind blowing devices.

came to the door of the room where Liang Yu lived and knocked on the door: "Is Sister Liang Yu here? I'm Liu Yu." "Liu Yu, is there anything wrong with coming to me so soon? How is the copper ingot refining? I will not show favoritism. The door opened, and Liang Yu's voice was heard. "That's right, can Sister Liang Yu do me a favor? I need a blower, I hope Sister Liang Yu can provide one, so that I can better learn smelting skills." Liu Yu looked at Liang Yu expectantly.
