The engineering team used batch-based 24-hour uninterrupted construction. After three days of mining, two-thirds of the trees and plants on the entire island were shoveled, and countless wood was thrown into the garbage ship as waste, and a large area of ​​open space appeared in the center of the island.

During these three days, the freighter was not idle, and more materials were transported to the island. A simple dock was built, and large cranes were lifted and lowered back and forth, and boxes of stamped steel plates passed through the Caribbean Sea and were transported to the beach.

The construction efficiency of the clone engineering team was extremely fast. On the tenth day after the construction of the Star Island began, the foundation of the human freezer was dug out.

The foundation depth is forty meters, and it is still circular, with a base area of ​​50,000 square meters. The deeper the structure, the more it can resist natural disasters such as tsunamis and hurricanes.

In Zhang Heng's plan, the structure of the human body's freezing center is composed of special steel, even the underground structure. Just like building blocks, it only takes construction and welding. With five cranes working at the same time, it took two days to lay a thick layer of steel plate on the base of the foundation, which is 40 meters deep, but there is a circular blank with a diameter of 30 meters in the center of the foundation.

This round blank part was naturally not for placing the moonlight. After the foundation was laid, whether intentionally or unintentionally, the engineering team suddenly stopped building the foundation and covered the foundation with a huge curtain, covering the huge deep pit.

At this moment, in the deep pit of the foundation, Zhang Heng and the person in charge of the cloning engineering team nodded, then suddenly disappeared and headed to the radiation plane again. When he came back for 24 hours, a huge columnar machine with a diameter of ten meters and a length of five meters appeared in front of him!

If anyone who has been dealing with tunnel projects for many years can recognize this machine at a glance - this is a full-section tunnel boring machine!

The full-section tunnel boring machine is a combination of a rotating cutter and a hob. By rotating and extruding the soil and rocks, a special excavation equipment is dug into a tunnel in the mountain rock formation. Foreign countries are generally abbreviated as ‘tbm’. Because the drill bit of this machine is like a round shield, it is called the ‘shield machine’.

Obviously, Zhang Heng was planning to use this tunnel boring machine to dig out a secret base underground.

Compared with the use of drilling and other methods, the excavation speed of the tunnel boring machine is several times that of the conventional drilling speed, and the maximum daily drilling depth can reach 500 meters. It has the advantages of fast, safety, economical, and small interference to rock formations. Moreover, this tunnel boring machine is an advanced machinery obtained from the radiation plane, with faster efficiency and speed and higher safety.

The huge volume of ten meters in diameter means that the diameter of the tunnel it excavated is more than ten meters. Moreover, this boring machine adopts extruded excavation, so there will be no excavated soil. The machine will directly open a channel underground, and all the soil will be squeezed around and become extremely dense.

With the working efficiency of a tunnel boring machine, which is about a hundred years older than reality, a channel that leads to a depth of thousands of meters underground can be drilled on the Star Island at most half a month.

That’s right, this is the third secret base that Zhang Heng has prepared to build in addition to the cloned production center and the hive. This base will be countless times more secret than the hive!

Because in the design, the location of this base will be located inside the undersea rock formation in the Caribbean Sea, at an altitude of two thousand meters. In this case, even if there are irreversible huge disasters in the world, such as the outbreak of sunspots, nuclear war, etc., it will not affect this undersea base that is thousands of meters deep, unless it is destroyed by the earth.

As for the so-called submarine base structure, Zhang Heng designed it as a spherical shape, which is also the most resistant to crust extrusion. Zhang Heng wants the base to achieve the degree that even if the crust movement is encountered, it will not damage the submarine base.

As for the soil excavated underground, Zhang Heng also had a solution. He directly transported the last molecular transmitter of the radiation plane here, then connected the honeycomb and the Star Island, and directly transported the excavated soil there, perfectly solving the efficiency problem and the danger of being discovered.

When the full-section tunnel boring machine drilled into the ground, the human body freezing center on the surface continued to start construction. The surface engineering concealed the huge movements underground. Even if a little curious traveler drove the boat to the edge of the island to observe secretly, he could not notice that the construction site of the island was hidden under the construction site of the island, and there was a secret that was enough to shock the world!

Time passes slowly, the old year passes, Zhang Heng's plane has entered a new year, and the development and transformation of Hengxing Island has also entered a steady period. The surface can be completed in three or four months, but it may take longer to underground.

However, these are not big problems. With the guards of the Cloning Legion, Zhang Heng did not need to continue to stay here. Just at the beginning of January of the new year, he received a call from Yuehua again.

"His Excellency Commander, there is good news that the US FDA has officially announced that the 'anti-frozen nano-agent' has passed clinical trials and new drug applications, meeting the certification standards, and you can already make anti-frozenants."

"Very good. Those consortiums are indeed very fast to use. If it is usually done, it will take at least two to three years for the anti-refrigerant to pass the application, right?" Zhang Heng said with relief.

"Yes, if Williams and several other American consortiums had not put pressure on the authorities, it would have been expected that the anti-refrigerant would take about five years to pass the application. Unlike now, it passed the certification in just half a year, and the time was ten times faster." Yuehua said excitedly.

"It seems that India's human body freezing center can be opened. Yuehua, you will select a public relations team from the company. I need to spread advertisements on a large scale around the world, especially online publicity. You can buy hot search entries such as Google and Baidu to inform them of the existence of the Indian Human Body Freezing Center and the Virgin Islands Human Body Freezing Center!" Zhang Heng ordered.

"clear."

"Also, the company's pharmaceutical factory has been built. Can we start manufacturing anti-refrigerants?"

"Your Excellency Commander, I'm afraid it's not possible yet." Yuehua suddenly felt a little stuttered, "We have obtained the international gmp certification certificate and have passed the provincial drug administration certification. However, because we are injectables, we must pass the national certification to be considered qualified. However, the country has not allowed us to pass the certification for a long time, because our factory has quality problems and refuses to issue us a 'pharmacy manufacturer license'."

Zhang Heng suddenly looked cold when he heard this, "Since this is the case, we don't force it. We will directly acquire a pharmaceutical factory in India. We must start the production of anti-refrigerant before the end of the month!"

"But what about China?" Yuehua felt a little regretful. "If a large pharmaceutical factory with an investment of $300 million cannot start construction, wouldn't it be a pity?"

"This matter will be resolved sooner or later, but not now. What we have to do now is to open the human freezing center as quickly as possible." Zhang Heng said, "The sooner it is opened, the more beneficial it is for us."

"clear."

After giving Yuehua instructions, Zhang Heng quietly hung up the phone, suddenly frowned, and murmured in a low voice, "Sure enough, because the anti-refrigerant is not reviewed in China, is the country dissatisfied with me?"
