In the shop of the "Dali Blacksmith Shop", five sets of blacksmith shops were lined up. Five young men of fifteen or sixteen were shirtless, wearing tights made of cowhide, holding hammers in both hands, and smashing the red steel ingots burned on the anvil.

The sledgehammer was heavy, and it made a "clang" sound when hitting the steel ingot. Countless sparks were squirting out. The impurities in the steel ingot were bombarded out by a huge force, and the steel ingot was gradually becoming pure.

More than a dozen younger teenagers were helping the five teenagers. They were so hot that they were sweating all over, but they did not dare to carelessly carry the heavy iron pliers and constantly flip the steel ingots on the anvil.

The boys who had made a black hair blow were sweating like slurry. They were panting in a low voice, and the hammer in their hands kept hitting down at a strange frequency. Their breathing was heavy and long. With one breath and one breath, their chest and abdomen were rising and falling rapidly.

Beside the young men, five burning stoves emitted a rush of high temperatures. In each stove, Chu Tian buried a soybean-sized fire-attribute spirit crystal. Under the stimulation of the high temperature, tiny but pure spiritual marrow of heaven and earth constantly leaked out in the spirit crystal.

Chu Tian's soul thoughts enveloped the entire blacksmith shop. These spiritual corpses of heaven and earth were divided into more than twenty strands and slowly penetrated into the bodies of these apprentices.

The apprentices themselves used the "Nine-Turning Heavenly Furnace Method" taught by Chu Tian. The high temperature emitted by the burning charcoal in the furnace, and the spiritual marrow of heaven and earth emitted from the small spiritual crystal were constantly sucked into their bodies.

Their skin was red, just like charcoal.

The heat in their bodies was rolling, and the hot heat was training their internal organs, flesh and meridians. As they moved, there was a faint trace of gray impurities in their shiny sweat.

Slowly, but very firmly, the impurities in these apprentices' bodies were tempered by the Nine-Turn Heavenly Furnace Technique, and their flesh, muscles and bones became purer and pure, and their strength was increasing little by little.

In the yard behind the Dali Blacksmith shop, more than twenty stoves were burning, and there was a pair of iron-smashing tools next to each stove. More than twenty children, young, from seven or eight to eleven or eleven, were carrying small iron hammers and gritting their teeth and smashing them hard at the small iron block on the anvil.

These children are young, have little strength, have never practiced before, and have never taken any pills to assist in cultivation. Compared with the five teenagers who filled their shops in the blacksmith shop, these children have a much worse foundation.

If the foundation is poor, there are teaching methods with poor foundation.

The boys outside can already forge fine steel ingots and refine better steel. The children in the backyard cannot do anything else, but according to the ratio given by Chu Tian, ​​it is quite competent to use a small crucible to refine certain special alloys.

The children smashed a bunch of iron and sat on the door hole between the shop and the backyard in front. Chu Tian, ​​who was drinking with his legs crossed his head, looked up at the sky and shouted lightly: "The heat is here, take the mold, be careful, and inject the melted iron into the mold!"

A group of children dropped the hammer in their hands, gasped for a few heavy noises, picked up the iron tongs beside the anvil without saying a word, and carefully clamped out a crucible with high temperatures and radiant heat from the red-burning stove.

The mold was prepared next to the stove. The children gritted their teeth and lifted out the crucible weighing dozens of kilograms and the alloy juice inside, and carefully injected the alloy juice into the mold.

Mars splashed everywhere, splashing more than two feet high.

The children were wearing tights made of animal skin, and sparks splashed on their legs, which only made them sweat a little more and did not cause any harm to them.

After a short while, all the alloy juice was injected into the mold. Chu Tian waved his hand and said in a deep voice: "Okay, sit on the ground immediately, practice the martial arts taught by my master. Hey, this is related to your future achievements. Don't be lazy!"

Chu Tian stood up, carried a whip with thin iron wire wrapped around the surface, and walked slowly to the children.

The children did not dare to neglect them. They hurriedly sat cross-legged next to the mold that kept emitting terrible high temperatures, pressed their left hand on their chest and their right hand on their lower abdomen, and began to practice the Nine-Turn Heavenly Furnace Method according to the breathing method taught by Chu Tian.

Widths of hot air continued to seep into the bodies of these children. Seeing the white air coming out of their heads, many of the children's breathing became extremely heavy, and the breath erupted from their mouths was extremely hot. If a thin piece of white paper was placed in front of them, the white paper would probably burn out of thin air.

Chu Tian nodded with satisfaction.

The children introduced by several shopkeepers around are all simple and kind-hearted children.

No one is lazy or scheming, and no one is tempted. It has been seven or eight days since I accepted them. No matter what Chu Tian asked them to do, these children can do it well.

"Not bad!" Chu Tian nodded with satisfaction.

Looking at these children who are working wholeheartedly, Chu Tian flicked his finger and a red top-quality spiritual crystal appeared in his hand. With the thumb and index finger on his right hand, the spiritual crystal was crushed. Chu Tian picked up more than twenty of the smallest pieces and threw them into the furnaces one by one.

A powerful voice came from the blacksmith shop: "Master Dali? Master Dali? Let's bring a few good brothers here. Hey, can you build a strong bow? At least you must have a strong bow that can withstand 300,000 kilograms of strength. If it can, it can be as high as possible!"

Chu Tian narrowed his eyes.

A strong bow with a strength of 300,000 kilograms?

The weights and measures of the heaven here are also consistent with the world of Tianlu. It seems that there is a mysterious force that unifies the weights and measures of the two worlds that are extremely far apart. The force of 300,000 kilograms is just the level of ordinary three dragons!

A bow that withstands this strength can also be considered a strong bow?

With a smile, Chu Tian walked into the blacksmith shop in front slowly and smiled at the man who came to build the three pavilion machete last time, saying, "How can you, why can't it? However, the strong bow that can withstand 300,000 kilograms of strength, my materials are not good. If several good men can find some good materials..."

Several men with tall bodies with arms that were more than ordinary people had a fraction of that of ordinary people and nodded quickly and untied several huge packages from behind.

In a short while, several beast horns that emitted powerful aura were placed in front of Chu Tian, ​​several python main tendons, and a pile of dark metal ore.

Chu Tian grabbed the beast's horn and broke it by, picked up another main tendon and pulled it hard.

With a buzzing sound, the main tendon was beating violently. Chu Tian used millions of kilograms of strength but failed to pull the main tendon.

"Good materials are just used to forge a bow of 300,000 kilograms, which is a waste! If you do it, I will forge a good bow of 600,000 kilograms for you, how about?" Chu Tian looked at the handsome men with a smile.
Chapter completed!
