Bridges and tunnels each have their own advantages and disadvantages, and for a while Zhao Ming couldn't figure out which one was more suitable.

However, he is not a bridge expert and cannot design a bridge on site. All he can do now is add an extra tunnel under the canal.

After thinking about it, Zhao Ming got out of the RV, put on his steel suit, put the RV away, and continued to build the canal alone.

Somewhere near the seaside, after digging the river channel, Zhao Ming dug a large cross-cut ditch under the river channel.

The ditch is 100 meters wide, enough for cars and trains to use together, and a load-bearing wall is added to separate it.

A special transparent prefabricated panel is used as the ceiling of the tunnel above the trench, so that some light from above can penetrate through the 30-meter-deep seawater.

If the passengers in the tunnel are lucky and look up when passing the intersection, they may be able to see the bottom of the passing ship.

If people on the ship lower their heads, they can also see the interior of the brightly lit tunnel, and they may also see passing vehicles, or even trains.

After working for a few more hours, when the sun rose again from the east, a straight channel 30 meters deep, more than 300 meters wide (the trapezoidal channel was wider at the top than below), and 200 kilometers long had appeared on the ground.

Of course, there is still some distance between the two ends that is not connected, so the canal is still dry.

"Well, what it looked like before the canal was built... This is rare. I have to take a photo of it. I will build a museum here in the future. Then I can put the large photos on display in the hall. It will be interesting."

After Zhao Ming finished speaking, he took out his SLR camera from his pocket, pointed it downwards and took pictures.

After taking the photos, the only thing left to do is to connect the entire canal. This workload is negligible compared to the entire canal.

Zhao Ming yawned, and once again released his mental power to wrap the remaining dozens of meters of sand and soil, and immediately collected them into the system space as raw materials for the building materials factory.

The seawater from the Mediterranean rushed into the canal along the river. Fortunately, the AB glue can be bonded normally under water and does not affect the laying of the remaining canals at all.

After finishing this end, Zhao Ming didn't bother to expend mental energy to open the portal, and turned on the automatic driving function of the steel suit to fly to the other end.

With a pop, a cone-shaped cloud appeared around Zhao Ming's waist. This was a sign that the steel suit had broken through the speed of sound.

Flying at several times the speed of sound, the 200-kilometer journey arrived almost in an instant. At this time, the water coming from the Mediterranean was still far away.

Zhao Ming, who was familiar with the road, also followed the same method on this side of the Red Sea. In less than two minutes, he opened the opening here and completed the laying of the canal.

"The meeting of the sea water on both sides must be very beautiful. This is a rare scene."

After Zhao Ming finished speaking, he started the thrusters under his feet again, and at the same time turned on the video recording function of the steel suit, turned around and flew back along the river.

Soon, he came to the midpoint between the two seawaters, suspended in mid-air by the river, waiting for the seawater to come over.

After a while, the sound of rumbling water came from both ends at the same time, and the waves of the sea water were dyed with a layer of red light under the sunlight.

Closer, closer, closer.

Finally, the water from the Red Sea and the water from the Mediterranean collided head-on for the first time.

boom--

A huge wave rose into the sky.

It jumped high over the river bank, splashing water everywhere.

Under the action of inertia, the sea water on both sides could not completely stop for a while, and the water level at the intersection was temporarily raised beyond the height of the river embankment, overflowing to both sides.

But there was nothing but sand here. The sea water quickly seeped into the sand and disappeared, and the water level in the canal slowly dropped back.

At this point, a Grand Canal with a length of 200 kilometers, enough for multiple large aircraft carriers to pass through in parallel, was officially completed.

Total construction period - 1 day.

Design, construction, supervision, and acceptance—all by Zhao Ming.

"I didn't expect that building a canal would be quite fun." Zhao Ming returned to the ground and released the RV again. "Let's take a rest first. There is a canal to be dug later."

The Panama Canal is only over 60 kilometers long and is the narrowest place between North and South America.

The original choice to build the canal here was because it was more trouble-free, because there is a large area of ​​water in the middle of these dozens of kilometers that can be directly used. In fact, the length that needs to be excavated is much less than 60 kilometers.

However, Zhao Ming is not very satisfied with this place, because in the future, the main shipping may start from the northern Gulf of Mexico, go west into the Pacific, and then cross the entire Pacific to reach the Ming Dynasty.

If the Panama Canal is built like in the main world, ships will have to go from the Gulf of Mexico to the Caribbean Sea before passing through the Panama Canal.

The entire voyage is three to four thousand kilometers longer.

How can the obsessive-compulsive disorder patient Zhao endure this?

So Zhao Ming decided to work harder on his own. This time, he started directly from the Gulf of Mexico and went straight to the Pacific Ocean. The length was the same as the Suez Canal, which was about 200 kilometers.

After the previous training, Zhao Ming felt that his mental strength had become more refined. It was estimated that after he had a good rest, he would be able to finish the canal in one go.

Since it's not in Panama, let's call it the "Mexico Canal".

After setting up the navigation point, Zhao Ming let the AI ​​inside the steel suit take charge of automatic driving while he closed his eyes and slept inside the suit.

After flying to the predetermined location, his mental strength was fully restored, and a brand new "Mexican Canal" appeared in the world soon.

"Zhang Yan, are you there?" Zhao Ming called through the system.

"Yes, boss, what are your orders?"

"I have good news for you. I have just dug two canals, one is the Suez Canal and the other is the Mexico Canal."

"Eh? Boss, when did you send the robot to do the construction? I don't even know."

Zhao Ming laughed, "What kind of robot? I did it myself. Your boss, I personally dug a large canal in one day. Isn't it amazing?"

"What? Boss, you dug it alone? It only took one day?"

"That's to tell you, with mental power and system space, you can do a lot of things, such as digging canals and tunnels. You should also practice more in the future, so that you can improve your superpowers."

"Okay, boss, I will work hard."

"Yeah. By the way, I just updated the navigation data. Please help me inform everyone of the existence of these two canals to avoid misunderstandings."

"OK."

"Then I'll leave first. I have to go test-fly my new plane."

"Boss, have you bought a new plane again?"

"Yes, this time it is a high-altitude and high-speed electric jet aircraft. The cruising speed can reach Mach 5, which is five times the speed of sound. Isn't it amazing?

If there is no problem, I will equip you with one, otherwise you will have to fly for more than ten hours to Base 10, which is a waste of time."
