Chapter 251: The Cross-Border Trader

Based on experiments conducted on death row prisoners, Meng Yifan deduced that a Third Grade Expert should be able to successfully absorb the energy within a Second Grade Demon Core, while a Fourth-Grade Powerhouse should be able to absorb the energy within a Third Grade Demon Core.

Zhang Sanfeng was originally a Fifth-grade Cultivator; although his cultivation has now regressed to the Fourth Grade, his strength is still far more formidable than an ordinary Fourth-Grade Powerhouse, so for him, there must be a way to absorb the energy within a Third Grade Demon Core.

As for the potential physical mutations that might occur after absorbing a large amount of Demon Cores, that will have to be left to Zhang Sanfeng to decide whether or not to absorb them.

However, Zhang Sanfeng is already nearing the exhaustion of his Spirit Power and could face death and the dissipation of his Dao at any moment; having the energy of Demon Cores to replenish himself is quite good, so he shouldn't be picky about the energy in the Demon Cores not being as pure as the energy in Spirit Stones, right?

This is like a person dying of thirst in a dry desert; at such a time, let alone being given a cup of dirty water, even if they were given a cup of urine, they would gulp it down.

"I'll take all the Demon Cores harvested this time, but what other valuable things should I bring back to Earth?" Meng Yifan muttered.

After experiencing this battle, the AK47 ammunition is almost completely exhausted, the M67 Grenades are nearly used up, and even the Gustav Rockets have been fired.

These modern weapons have immense power, but they are consumed very quickly; one battle has emptied out Meng Yifan's entire stock, and he has no choice but to return to Earth to replenish a batch.

However, back on Earth, the AK47 ammunition, M67 Grenades, and Gustav Rockets in Meng Yifan's base have already been cleared out.

If he wants more, he can only purchase them from the outside; this time, Meng Yifan is also preparing to buy high-power generators, transformers, and other supplies, all of which require a large amount of money.

In modern society, money isn't everything, but without money, you can't do anything.

Before returning to Earth, Meng Yifan must decide what to bring that can be exchanged for a large sum of money on Earth, not only to purchase sufficient supplies but also to maintain the normal operation of the base.

"What is there in Luolong County that would be extremely valuable after being brought back to Earth?" Meng Yifan pondered deeply.

Crossing over once consumes a massive amount of Yin Soul Energy; if not for the fact that he had just experienced a great battle against a Demon Beast siege, Meng Yifan wouldn't have been able to gather enough energy to return to Earth.

The cost of crossing back once is very high, and coupled with the limited space inside the Space Ring, Meng Yifan must utilize the space rationally and bring back the items with the highest cost-effectiveness to Earth.

The first thing Meng Yifan thought of was the Pill; soldiers need both Condensing Qi Pills and Qi Replenishing Pills to practice martial arts, and he doesn't even have enough for his own use, so he certainly won't sell them.

When Meng Yifan was auditing the Warehouse, he also found a batch of Six Yang Pills for nourishing yin and tonifying yang, as well as some Whitening Pills and Scar Removal Pills.

To Meng Yifan, these pills are completely useless, but if brought to Earth, they would be priceless treasures.

Meng Yifan had used his Spiritual Power to examine the Six Yang Pills and discovered that they used several precious medicinal herbs; the medicinal efficacy is certainly much better than the Blue Small Pill, and because the Great Martial Heavenly Dynasty World has rich Spirit Qi, the herbs used to make the Six Yang Pills grew in such an environment and also contain some Spirit Qi.

This bit of Spirit Qi, if provided to an Immortal Cultivator for practice, would be a drop in the bucket and appear insignificant, but for ordinary people, it can fundamentally strengthen the kidneys and cultivate the essence, nourishing the body.

Potent drugs like the Blue Small Pill cause more harm to the body the more they are taken, but the Six Yang Pills are different; after taking them, not only can a man's vigor be greatly boosted, but they can also nourish the body, making one feel refreshed and increasingly healthy.

The Six Yang Pills are prepared for men, while the Whitening Pills and Scar Removal Pills are prepared for women; their medicinal effects are also astonishing, and those top-tier cosmetics on Earth are just industrial waste compared to the Whitening Pills and Scar Removal Pills.

"As long as these three types of pills are handled well, they will definitely sell for a good price. Besides these, what else should I bring? How about silver?" Meng Yifan thought for a moment and then rejected silver.

Because silver is not valuable on Earth, selling for only five yuan per gram, the profit from bringing silver back is too low.

One must know that Meng Yifan is now a cross-border trader between two worlds; if he brought silver back, those cross-border smugglers would laugh their heads off if they found out.

"I can bring back some Monster Beast Meat; these Monster Cured Meats contain energy, and even if ordinary people eat them, they can strengthen their bodies and increase their strength."

Meng Yifan's eyes lit up, thinking that bringing back sausages and cured meat made from Monster Beast Meat was a good idea.

However, it might be somewhat difficult to sell the sausages and cured meat for a sky-high price.

He must make those wealthy people aware of the benefits of the Monster Sausage and Monster Cured Meat so that they would be willing to pay a high price.

Meng Yifan continued to ponder, and suddenly his heart stirred, and he muttered: "If there is something on the Great Martial Heavenly Dynasty World that doesn't exist on Earth, it must be the Heaven and Earth Spiritual Qi. If I bring back some air from the Great Martial Heavenly Dynasty that contains Spirit Qi to sell, it would surely sell for a sky-high price, right?"

On Earth, there are people selling fresh air from Mount Fuji, claiming it contains rich negative oxygen ions, which can make people feel refreshed and happy after breathing it, and can even lower blood pressure, reduce the incidence of cardiovascular and cerebrovascular diseases, and so on; in any case, the advertisements blow it out of proportion.

Meng Yifan used to just watch it as a joke; those palm-sized Air Cans actually sold for three or four hundred yuan—who would be foolish enough to spend so much money just to buy a can of air?

As it turned out, it was beyond Meng Yifan's expectations; there really were people, and quite a lot of them.

Meng Yifan specifically checked the news and found that there really were people who relied on selling air, selling 47 cans of air in one year for a value of over 4 million.

This is even more than what Meng Yifan earned as a mercenary; one can only say that poverty limited his imagination.

"The air in the Great Martial Heavenly Dynasty contains Heaven and Earth Spiritual Qi. If it were provided to an Immortal Cultivator like Zhang Sanfeng for practice, it would certainly not be enough, but if ordinary people were to absorb it, it could truly make them feel refreshed and invigorated. If absorbed over a long period, it could truly prolong their lives and slowly improve their constitutions."

"Those Air Cans from Mount Fuji and the Hulunbuir Grassland on Earth are not even worth mentioning compared to the air of the Great Martial Heavenly Dynasty."

Thinking of this, Meng Yifan had already decided: this time upon returning, he would bring the Six Yang Pills, Whitening Pills, Scar Removal Pills, sausages and cured meat made from Monster Beast Meat, and the fresh air of the Great Martial Heavenly Dynasty.

Meng Yifan began to make preparations; the pills didn't take up much space, the sausages and cured meat took up half the space in the Space Ring, and the remaining space would be used to store the air.

Without containers like oxygen tanks, Meng Yifan could only use Demon Beast skin to make some air bags, and then cast a spell to guide the surrounding air into the air bags.
