All he needed now was the actual space cannon, which was built according to the energy channels in the human body. It should be mostly finished by now.
Building the space cannon was a major project, and the country had already started working on it over a week ago. Viclan, Branco, and several other scientists were in charge. Himmel Soan only needed to work on the core structure.
The most vital part was the spiritual essence. After that was the compression structure that mimicked the function of the dantian.
These two parts were essential to the space cannon. Once Himmel Soan figured out how to build them, the space cannon would almost be finished.
Now that he had succeeded in reproducing the spiritual essence, mimicking the function of dantian wouldn't be too difficult.
He also had a backup plan. If nothing worked, he would use himself as the energy source, although it would have some detrimental effect on his health.
