Chapter 280

When Elder Sun had obtained both those black zirconiums, he had returned to his immortal cave to research them, finding that it was really incomparably profound.
But when he tried to circulate his spiritual qi in accordance to those diagrams, he found that he was unable to undergo a full circulation.
After testing it several times without succeeding, he had finally undergone one test where his meridians had almost exploded from the forceful circulation.
Feeling that something was wrong, he had studied the diagrams for two full days, finally coming to the conclusion that he was still missing a portion!
That infuriated him so much that he almost coughed up blood. Naturally, he had come to find Long Chen.
Long Chen took out a black zirconium, the exact same as the previous two he had given Elder Sun. Seeing that stone, Elder Sun was filled with rage.
"Old fellow, you can choose. Do you want to do this shady deal once, or twice?" snorted Long Chen.
Since he had already revealed his feelings for him, Long Chen was too lazy to act polite. Long Chen's meaning was clear: if you want the complete technique, you'll need to risk being cheated again.
But Long Chen had obtained a huge number of precious medicinal ingredients. Those were treasures that had their own value.
And so Elder Sun really didn't have much of a choice. He looked from that black stone to the list.
"Fine, I agree. But you have to swear that once I obtain those things, you have to hand over what's in your hand right now." Elder Sun gritted his teeth.
This time the quantity of medicinal ingredients on the list was a bit lower than before. However, their quality was also of a level higher. He knew that the price this time wouldn't be much lower than the last time. In fact, it might even be a bit higher.
And so if he did agree, then all his lifetime savings would be gone. But if he refused, then half of his savings would have disappeared for nothing. He was unwilling for that to happen.
"Fine, I, Long Chen, swear that if Elder Sun can gather everything on this list without one missing, I will definitely hand over what is in my hand to Elder Sun. If I violate this oath, let me be struck by heavenly lightning," swore Long Chen.
The heavenly lightning oath was an extremely poisonous oath amongst people. If you broke it, your soul would scatter and you would never reincarnate.
