Zhao Ling stayed in Zhu Zhuyun's sleeping quarters for three days. On the fourth day, he embraced Gu Yuena and flew through the air, returning to his mansion. It had to be said, Gu Yuena was truly worthy of being the Silver Dragon King, possessing the body of a dragon. In terms of physical constitution, she was far superior to his other wives.
Looking at Gu Yuena, who was deeply asleep in his arms, Zhao Ling gently kissed her on the head. He then carefully placed her on the bed and tucked her in. This girl was someone he had worked hard to win over, so he had to dote on her like a treasure. Afterward, Zhao Ling turned and left Gu Yuena's room. Feeling the somewhat dazzling sunlight, he estimated it was around two o'clock in the afternoon.
He planned to visit the alternate compound. He hadn't been there for over five years. He wondered if Lou Gao and Tai Tan had managed to create the Guan Yin's Tears there. He also wondered if they had managed to create the imitation version of the Cloud Piercing Shuttle that they had been trying to produce.
Previously, before Zhao Ling comprehended spatial laws, the Cloud Piercing Shuttle was his primary mode of travel. But ever since he comprehended spatial laws, he had given the Cloud Piercing Shuttle directly to Lou Gao and Tai Tan for research. After so many years, they should have achieved some results, right?
Upon arriving at the alternate compound, Zhao Ling found that it had changed significantly, but the one constant was the busy people. He also saw six or seven smaller Cloud Piercing Shuttles placed next to his own enormous Cloud Piercing Shuttle. It was fortunate that the compound's area was large enough; otherwise, these Cloud Piercing Shuttles would take up an extreme amount of space.
Zhao Ling's arrival was quickly noticed by the busy Lou Gao and Tai Tan. Both of them put down their work and walked towards him.
"Brother Zhao, you're here! I have good news for you. We've produced the Guan Yin's Tears you mentioned. Unfortunately, the raw materials are extremely hard to find, so we only made one set."
Zhao Ling saw Lou Gao approach, holding a transparent, teardrop-shaped hidden weapon that didn't look very large. He took the Guan Yin's Tears and examined it carefully before nodding.
"Hmm, this is indeed Guan Yin's Tears. Don't let its seemingly harmless appearance fool you; this item can ignore defenses. In the hands of a Titled Douluo, it can even harm deities whose foundations are not yet stable. We should keep this item within our own ranks and not let it spread, otherwise, it could easily cause harm to our own people."
"I agree..." Lou Gao nodded in deep understanding. "However, to be honest, after manufacturing this, we haven't even tested its power. On one hand, none of us can activate it, and on the other hand, we haven't found a suitable target for testing."
"Lord, can you activate this item and show us?" Tai Tan looked at Zhao Ling with some curiosity. He was still somewhat incredulous about the power of Guan Yin's Tears. Could this thing really injure a deity after activation? It seemed very unbelievable to him.
"Activating this item is no problem for me, but this item also can't harm me." Zhao Ling said, then directly activated the Guan Yin's Tears towards an empty space in front of him. In an instant, the Guan Yin's Tears flew out with a piercing sound. It flew incredibly fast, so much so that Lou Gao and Tai Tan couldn't see it with their naked eyes. But in the next moment, Zhao Ling's figure disappeared from his original spot, and at the same time, he appeared in front of that empty space. He extended two fingers and gently caught the Guan Yin's Tears that was flying through the air.
This scene made Lou Gao and Tai Tan exchange glances. Although they had long known that Zhao Ling's strength was definitely beyond that of a Limit Doulou, to disappear from one's spot and instantly reappear hundreds of meters away, effortlessly catching the Guan Yin's Tears—an item capable of harming deities—with two fingers... they felt that even the gods might not be able to do that.
Zhao Ling then put the Guan Yin's Tears into his storage space and looked at the imitation Cloud Piercing Shuttles in the distance. "Have you started mass-producing those Cloud Piercing Shuttles? How fast can the fastest one fly? How far can it fly?"
"It's not exactly mass production; we've only produced less than ten in total. As for the speed, if there are enough spirit stones, the fastest one can fly about 5,000 li a day." Tai Tan pointed to one of the Cloud Piercing Shuttles and introduced it to Zhao Ling. "Although it's far inferior to yours, it's basically sufficient."
5,000 li is 2,500 kilometers. Calculating it, it's not bad. However, compared to the flying machines of his previous life, it was still far inferior. But the Cloud Piercing Shuttle's power source wasn't fossil fuels; it used a modified formation to absorb the elemental power of heaven and earth as energy. In a sense, using the elemental power of heaven and earth or spirit stones as energy was far superior to the technological world of his previous life in terms of environmental protection.
Moreover, according to the historical development in the original work, after the third and fourth parts, the forest area of the entire Douluo Planet became smaller and smaller, and spirit beasts also became fewer and fewer. Many reasons were due to the development of technology, leading to severe environmental pollution in the third and fourth parts of the original work, following in the footsteps of his previous life's Blue Star. If this Cloud Piercing Shuttle, which used a modified formation as energy, could be widely promoted, it might be able to prevent severe environmental damage in future generations.
The only shortcoming was the lack of spirit stone mines on the Douluo Continent, and Zhao Ling himself had few spirit stone reserves. Simply relying on the modified formation to absorb the elemental power of heaven and earth was still insufficient. This made Zhao Ling want to try if he could scale up the production of spirit stone veins in his Eighteen Realms Sky Domain. Now, within the new God Realm, the elemental power of heaven and earth and the immortal spiritual energy were becoming more and more intense, and it even possessed primordial energy. If he could create spirit stone veins, then he could completely prevent environmental pollution in future generations of Douluo.
Zhao Ling took Lou Gao and Tai Tan aboard an imitation Cloud Piercing Shuttle and observed it carefully. He found that although the formation carving on this imitation Cloud Piercing Shuttle was not yet meticulous, it was generally usable. However, Zhao Ling still tentatively tried to modify the formation. With his current understanding of various rules, after he modified the formation, its absorption of the elemental power of heaven and earth was strengthened by about three times.
This made Lou Gao and Tai Tan exchange even more bewildered glances. They had spent a great deal of time researching this formation improvement. Initially, they could only replicate the formation on the original Cloud Piercing Shuttle 1:1. But they found that the formation on the original Cloud Piercing Shuttle couldn't activate this imitation Cloud Piercing Shuttle at all. Later, they spent a lot of time improving the formation to gradually make it operational. But for Zhao Ling to just casually tinker with it and strengthen the formation's absorption of the elemental power of heaven and earth by three times... With this threefold effect, the Cloud Piercing Shuttle might be able to completely break free from its reliance on spirit stones.
