They reached the end of the tunnel surrounded by trees.
Ahead of them was a unique hophornbeam statue. The sculpture was of an old farmer resting while he happily watched his saplings grow stronger.
Even though the statue was dark and not shocking, Meng Chao knew that it portrayed Jin Zhenglin, the old chancellor of Agricultural University.
Jin Zhenglin was an experienced agronomist and genomist, He had created more than one hundred ways to combine Earth's products with the creatures of the Other World, and he also took part in designing the 3D farms, which helped the production of food in a single unit to surpass Earth's production rate by fifty times. The facilities in the farm could even transform spirit energy into light for photosynthesis so that the 3D farms could be buried underground. It created a brand new man-made ecosystem.
