Jin Tian picked up the old yellow drawings in his hand and slowly unfolded them, and countless institutions appeared in front of him one by one.

These mechanisms are combined, is a fist-sized sphere, this sphere is called the blasting bomb, it is very popular here, often equipped in the army under the command of a certain force, although the combination of this sphere is simple, but the internal mechanism is numerous and small, once thrown out of the power is huge, it can instantly disable a strong person in the heavy realm of the second turn of the qi, and the scope is wide at the same time because it is inexpensive, of course, this is for a certain force, the blasting bomb has become the best choice as a weapon of war, and it is also one of the classic assessment questions of a caster in the qualification certification, the difficulty belongs to the upper middle。

After thinking carefully for a long time, Jin Tian began to inject a trace of Xuan Qi into the furnace, and the flames in the forging furnace rose all of a sudden, Jin Tian did not rush to put in the materials, but felt the flames in the furnace, and with the beating of the flames, Jin Tian's breathing also fluctuated.

Old man Jin looked at Jin Tian, a smile appeared on his face, and he nodded slightly, it seems that this kid really knows a lot, maybe he can really cast this blasting bomb successfully.

Then, after Jin Tian adjusted the Xuan Qi, he began to put in the materials, and at the same time, the sound of "clanging" began to come, and the Xuan Qi slowly flowed into the groove of the Xuan Iron Black Furnace along the corners of Jin Tian's clothes, and a drop of sweat flew up with Jin Tian's waving arm, jumping into the flames that jumped in front of Jin Tian's body, making a "snort" sound and emitting a burst of white smoke.

The casting materials on the table disappeared one after another, and on the other side of the table, all kinds of mechanisms gradually increased, and just as the casting was in full swing, a crisp "click" suddenly came, and I saw a crack the size of a little finger in the center of a piece of purple-gray metal.

Here, Old Man Jin said in his heart. This purple gold is famous for its strong rigidity, but the shortcomings are also obvious, that is, it is too brittle, too rigid is easy to break, the toughness of purple gold is very poor, and it is very difficult to forge, if you are not careful, the heat is slightly greater or the force is too strong, it will be broken, so it is also often called a threshold of a caster, and there are countless casters who are blocked by this threshold. After this pass, it can be said that the door of the first-class caster has already entered more than half of it.

Jin Tian closed his eyes slightly, calmed down, his breath fluctuated with the beating of the flames, after a while, Jin Tian opened his eyes and adjusted the Xuan Qi slightly, the flame in the black Xuan Iron Furnace changed slightly to a degree that was imperceptible to the naked eye, a purple light flashed, and another piece of purple gold was thrown into the flames, and it was instantly wrapped in flames.

An hour later, with a "click", another crack broke on the purple gold, Jin Tian glanced at it and did not stop, and immediately threw the third piece of purple gold into the furnace.

What does this kid want to do, and he doesn't stop? Although he didn't have much hope for Jin Tian, but Jin Tian put in another piece of purple gold without adjusting the flame, what is the difference between doing this and wasting materials, he didn't feel sorry for this material, but he was puzzled by Jin Tian's irrational approach at this time, Old Man Jin was confused, in his mind Jin Tian was not that kind of reckless person.

Jin Tian then fought against Zigangjin again without the slightest stop, and it was about to come another hour, and sure enough, Zigangjin's voice began to gradually change, Jin Tian's heart sank, sure enough!

Jin Tian gritted his teeth, his expression was tense, as if he had made up his mind, and he did not stagnate hammer after hammer.

Old man Jin was disappointed at the moment, it seemed that he was going to fail, forget it, it was not bad to be able to achieve such a result in just two months, and then he could barely pass it. It's just that the Casting Pavilion is more than ······ Alas, forget it.

An hour passed, and the expected sound of metal cracking did not appear, only Jin Tian was still waving the hammer.

Another quarter of an hour passed, Zigang Jin still did not react, and Old Man Jin's eyes widened at the moment, could it be that this kid was going to succeed?

Half an hour later, Jin Tian gently put down the mechanism in his hand and exhaled lightly, and sure enough, it was so.

Just now, when the purple steel gold was about to collapse, Jin Tian suddenly adjusted the flame slightly, and the purple steel gold did not crack in the end, Jin Tian had long suspected this in the first two castings, but it was written in the "Casting Law" that changing the flame at will when forging metal would lead to the failure of the caster, so Jin Tiancai did not make changes to the flame for a long time, and finally in the third casting, Jin Tiancai broke through the original understanding, fought hard, and successfully cast the required mechanism.

It seems that not all of what is said in the book is true. Jin Tian couldn't help but sigh when he thought of the experience just now.

Even the most difficult level of Zigang Gold has passed, and the subsequent casting process is naturally a matter of course, and two hours later, a metallic sphere with the size of a bowl mouth appeared in front of Old Man Jin.

"Master Jin, it's okay to pass the test. Jin Tian looked at Old Man Jin with a worried expression and said.

"Well, barely qualified, you have to continue to work hard" Old man Jin said this, in fact, his heart has already blossomed, my old eyes have not been spent, it seems that this time the bet is right, those old guys, hum.

The old man Jin was proud in his heart, how many years did the Red Jade City Casting Pavilion not raise his eyebrows in the Casting Pavilion Competition, and the decline in popularity led to the gradual decline of the Casting Pavilion in the Red Jade City, and finally the chief pavilion master actually said that this time the big competition could not enter the top ten, so he withdrew the Casting Pavilion in the Red Jade City.

This time, the Forge Pavilion is saved!

Old Man Jin was excited in his heart, but his face was still light and light, as if Jin Tian's achievements in casting techniques had nothing to do with him.

"Yes, Master Jin," Jin Tianying said.

"That, that outfit ······" Jin Tian stared closely at the forging road in front of him.

"I'll send it to you, but you must come back in a year to participate in the Casting Pavilion Competition," said the old man Jin.

"Casting Pavilion Dabi?" Jin Tian looked puzzled.

"A competition between casters, and next year you will represent the Forge Pavilion in Ruby City"

"But you must not fall behind in the cultivation of the casting technique, in the casting pavilion competition, the worst caster is also a second-grade caster!" Without waiting for Jin Tian to speak, Old Man Jin continued.

"Also, this is for you, this is my own cultivation of the casting technique, now I will give it to you, I hope it can help you in the cultivation of the casting machine" Old Man Jin took out a dirty bamboo slip from his arms and handed it to Jin Tian.

"Don't say anything like thanksgiving and praising me for my wisdom and martial arts, get out of here with your stuff, and remember to come back in a year. With that, the old man returned to the "old place", buried his head on the table and fell asleep.

Jin Tian bowed deeply to the old man curled up at the table with gratitude, and then walked out of the small and dilapidated house.

Jin Tian swore that no matter what, he would let the Casting Pavilion of Red Jade City have a place in the Casting Pavilion Competition!
